<h2> PREFACE </h2>
<p>Ancient Greek philosophy was divided into three sciences: physics, ethics,
and logic. This division is perfectly suitable to the nature of the thing;
and the only improvement that can be made in it is to add the principle on
which it is based, so that we may both satisfy ourselves of its
completeness, and also be able to determine correctly the necessary
subdivisions.</p>
<p>All rational knowledge is either material or formal: the former considers
some object, the latter is concerned only with the form of the
understanding and of the reason itself, and with the universal laws of
thought in general without distinction of its objects. Formal philosophy
is called logic. Material philosophy, however, which has to do with
determinate objects and the laws to which they are subject, is again
twofold; for these laws are either laws of nature or of freedom. The
science of the former is physics, that of the latter, ethics; they are
also called natural philosophy and moral philosophy respectively.</p>
<p>Logic cannot have any empirical part; that is, a part in which the
universal and necessary laws of thought should rest on grounds taken from
experience; otherwise it would not be logic, i.e., a canon for the
understanding or the reason, valid for all thought, and capable of
demonstration. Natural and moral philosophy, on the contrary, can each
have their empirical part, since the former has to determine the laws of
nature as an object of experience; the latter the laws of the human will,
so far as it is affected by nature: the former, however, being laws
according to which everything does happen; the latter, laws according to
which everything ought to happen. Ethics, however, must also consider the
conditions under which what ought to happen frequently does not.</p>
<p>We may call all philosophy empirical, so far as it is based on grounds of
experience: on the other hand, that which delivers its doctrines from a
priori principles alone we may call pure philosophy. When the latter is
merely formal it is logic; if it is restricted to definite objects of the
understanding it is metaphysic.</p>
<p>In this way there arises the idea of a twofold metaphysic—a
metaphysic of nature and a metaphysic of morals. Physics will thus have an
empirical and also a rational part. It is the same with Ethics; but here
the empirical part might have the special name of practical anthropology,
the name morality being appropriated to the rational part.</p>
<p>All trades, arts, and handiworks have gained by division of labour,
namely, when, instead of one man doing everything, each confines himself
to a certain kind of work distinct from others in the treatment it
requires, so as to be able to perform it with greater facility and in the
greatest perfection. Where the different kinds of work are not
distinguished and divided, where everyone is a jack-of-all-trades, there
manufactures remain still in the greatest barbarism. It might deserve to
be considered whether pure philosophy in all its parts does not require a
man specially devoted to it, and whether it would not be better for the
whole business of science if those who, to please the tastes of the
public, are wont to blend the rational and empirical elements together,
mixed in all sorts of proportions unknown to themselves, and who call
themselves independent thinkers, giving the name of minute philosophers to
those who apply themselves to the rational part only- if these, I say,
were warned not to carry on two employments together which differ widely
in the treatment they demand, for each of which perhaps a special talent
is required, and the combination of which in one person only produces
bunglers. But I only ask here whether the nature of science does not
require that we should always carefully separate the empirical from the
rational part, and prefix to Physics proper (or empirical physics) a
metaphysic of nature, and to practical anthropology a metaphysic of
morals, which must be carefully cleared of everything empirical, so that
we may know how much can be accomplished by pure reason in both cases, and
from what sources it draws this its a priori teaching, and that whether
the latter inquiry is conducted by all moralists (whose name is legion),
or only by some who feel a calling thereto.</p>
<p>As my concern here is with moral philosophy, I limit the question
suggested to this: Whether it is not of the utmost necessity to construct
a pure thing which is only empirical and which belongs to anthropology?
for that such a philosophy must be possible is evident from the common
idea of duty and of the moral laws. Everyone must admit that if a law is
to have moral force, i.e., to be the basis of an obligation, it must carry
with it absolute necessity; that, for example, the precept, "Thou shalt
not lie," is not valid for men alone, as if other rational beings had no
need to observe it; and so with all the other moral laws properly so
called; that, therefore, the basis of obligation must not be sought in the
nature of man, or in the circumstances in the world in which he is placed,
but a priori simply in the conception of pure reason; and although any
other precept which is founded on principles of mere experience may be in
certain respects universal, yet in as far as it rests even in the least
degree on an empirical basis, perhaps only as to a motive, such a precept,
while it may be a practical rule, can never be called a moral law.</p>
<p>Thus not only are moral laws with their principles essentially
distinguished from every other kind of practical knowledge in which there
is anything empirical, but all moral philosophy rests wholly on its pure
part. When applied to man, it does not borrow the least thing from the
knowledge of man himself (anthropology), but gives laws a priori to him as
a rational being. No doubt these laws require a judgement sharpened by
experience, in order on the one hand to distinguish in what cases they are
applicable, and on the other to procure for them access to the will of the
man and effectual influence on conduct; since man is acted on by so many
inclinations that, though capable of the idea of a practical pure reason,
he is not so easily able to make it effective in concreto in his life.</p>
<p>A metaphysic of morals is therefore indispensably necessary, not merely
for speculative reasons, in order to investigate the sources of the
practical principles which are to be found a priori in our reason, but
also because morals themselves are liable to all sorts of corruption, as
long as we are without that clue and supreme canon by which to estimate
them correctly. For in order that an action should be morally good, it is
not enough that it conform to the moral law, but it must also be done for
the sake of the law, otherwise that conformity is only very contingent and
uncertain; since a principle which is not moral, although it may now and
then produce actions conformable to the law, will also often produce
actions which contradict it. Now it is only in a pure philosophy that we
can look for the moral law in its purity and genuineness (and, in a
practical matter, this is of the utmost consequence): we must, therefore,
begin with pure philosophy (metaphysic), and without it there cannot be
any moral philosophy at all. That which mingles these pure principles with
the empirical does not deserve the name of philosophy (for what
distinguishes philosophy from common rational knowledge is that it treats
in separate sciences what the latter only comprehends confusedly); much
less does it deserve that of moral philosophy, since by this confusion it
even spoils the purity of morals themselves, and counteracts its own end.</p>
<p>Let it not be thought, however, that what is here demanded is already
extant in the propaedeutic prefixed by the celebrated Wolf to his moral
philosophy, namely, his so-called general practical philosophy, and that,
therefore, we have not to strike into an entirely new field. Just because
it was to be a general practical philosophy, it has not taken into
consideration a will of any particular kind- say one which should be
determined solely from a priori principles without any empirical motives,
and which we might call a pure will, but volition in general, with all the
actions and conditions which belong to it in this general signification.
By this it is distinguished from a metaphysic of morals, just as general
logic, which treats of the acts and canons of thought in general, is
distinguished from transcendental philosophy, which treats of the
particular acts and canons of pure thought, i.e., that whose cognitions
are altogether a priori. For the metaphysic of morals has to examine the
idea and the principles of a possible pure will, and not the acts and
conditions of human volition generally, which for the most part are drawn
from psychology. It is true that moral laws and duty are spoken of in the
general moral philosophy (contrary indeed to all fitness). But this is no
objection, for in this respect also the authors of that science remain
true to their idea of it; they do not distinguish the motives which are
prescribed as such by reason alone altogether a priori, and which are
properly moral, from the empirical motives which the understanding raises
to general conceptions merely by comparison of experiences; but, without
noticing the difference of their sources, and looking on them all as
homogeneous, they consider only their greater or less amount. It is in
this way they frame their notion of obligation, which, though anything but
moral, is all that can be attained in a philosophy which passes no
judgement at all on the origin of all possible practical concepts, whether
they are a priori, or only a posteriori.</p>
<p>Intending to publish hereafter a metaphysic of morals, I issue in the
first instance these fundamental principles. Indeed there is properly no
other foundation for it than the critical examination of a pure practical
reason; just as that of metaphysics is the critical examination of the
pure speculative reason, already published. But in the first place the
former is not so absolutely necessary as the latter, because in moral
concerns human reason can easily be brought to a high degree of
correctness and completeness, even in the commonest understanding, while
on the contrary in its theoretic but pure use it is wholly dialectical;
and in the second place if the critique of a pure practical Reason is to
be complete, it must be possible at the same time to show its identity
with the speculative reason in a common principle, for it can ultimately
be only one and the same reason which has to be distinguished merely in
its application. I could not, however, bring it to such completeness here,
without introducing considerations of a wholly different kind, which would
be perplexing to the reader. On this account I have adopted the title of
Fundamental Principles of the Metaphysic of Morals instead of that of a
Critical Examination of the pure practical reason.</p>
<p>But in the third place, since a metaphysic of morals, in spite of the
discouraging title, is yet capable of being presented in popular form, and
one adapted to the common understanding, I find it useful to separate from
it this preliminary treatise on its fundamental principles, in order that
I may not hereafter have need to introduce these necessarily subtle
discussions into a book of a more simple character.</p>
<p>The present treatise is, however, nothing more than the investigation and
establishment of the supreme principle of morality, and this alone
constitutes a study complete in itself and one which ought to be kept
apart from every other moral investigation. No doubt my conclusions on
this weighty question, which has hitherto been very unsatisfactorily
examined, would receive much light from the application of the same
principle to the whole system, and would be greatly confirmed by the
adequacy which it exhibits throughout; but I must forego this advantage,
which indeed would be after all more gratifying than useful, since the
easy applicability of a principle and its apparent adequacy give no very
certain proof of its soundness, but rather inspire a certain partiality,
which prevents us from examining and estimating it strictly in itself and
without regard to consequences.</p>
<p>I have adopted in this work the method which I think most suitable,
proceeding analytically from common knowledge to the determination of its
ultimate principle, and again descending synthetically from the
examination of this principle and its sources to the common knowledge in
which we find it employed. The division will, therefore, be as follows:</p>
<p>1 FIRST SECTION. Transition from the common rational knowledge of morality
to the philosophical.</p>
<p>2 SECOND SECTION. Transition from popular moral philosophy to the
metaphysic of morals.</p>
<p>3 THIRD SECTION. Final step from the metaphysic of morals to the critique
of the pure practical reason.</p>

<h2> FIRST SECTION—TRANSITION FROM THE COMMON RATIONAL KNOWLEDGE OF MORALITY TO THE PHILOSOPHICAL </h2>
<p>Nothing can possibly be conceived in the world, or even out of it, which
can be called good, without qualification, except a good will.
Intelligence, wit, judgement, and the other talents of the mind, however
they may be named, or courage, resolution, perseverance, as qualities of
temperament, are undoubtedly good and desirable in many respects; but
these gifts of nature may also become extremely bad and mischievous if the
will which is to make use of them, and which, therefore, constitutes what
is called character, is not good. It is the same with the gifts of
fortune. Power, riches, honour, even health, and the general well-being
and contentment with one's condition which is called happiness, inspire
pride, and often presumption, if there is not a good will to correct the
influence of these on the mind, and with this also to rectify the whole
principle of acting and adapt it to its end. The sight of a being who is
not adorned with a single feature of a pure and good will, enjoying
unbroken prosperity, can never give pleasure to an impartial rational
spectator. Thus a good will appears to constitute the indispensable
condition even of being worthy of happiness.</p>
<p>There are even some qualities which are of service to this good will
itself and may facilitate its action, yet which have no intrinsic
unconditional value, but always presuppose a good will, and this qualifies
the esteem that we justly have for them and does not permit us to regard
them as absolutely good. Moderation in the affections and passions,
self-control, and calm deliberation are not only good in many respects,
but even seem to constitute part of the intrinsic worth of the person; but
they are far from deserving to be called good without qualification,
although they have been so unconditionally praised by the ancients. For
without the principles of a good will, they may become extremely bad, and
the coolness of a villain not only makes him far more dangerous, but also
directly makes him more abominable in our eyes than he would have been
without it.</p>
<p>A good will is good not because of what it performs or effects, not by its
aptness for the attainment of some proposed end, but simply by virtue of
the volition; that is, it is good in itself, and considered by itself is
to be esteemed much higher than all that can be brought about by it in
favour of any inclination, nay even of the sum total of all inclinations.
Even if it should happen that, owing to special disfavour of fortune, or
the niggardly provision of a step-motherly nature, this will should wholly
lack power to accomplish its purpose, if with its greatest efforts it
should yet achieve nothing, and there should remain only the good will
(not, to be sure, a mere wish, but the summoning of all means in our
power), then, like a jewel, it would still shine by its own light, as a
thing which has its whole value in itself. Its usefulness or fruitlessness
can neither add nor take away anything from this value. It would be, as it
were, only the setting to enable us to handle it the more conveniently in
common commerce, or to attract to it the attention of those who are not
yet connoisseurs, but not to recommend it to true connoisseurs, or to
determine its value.</p>
<p>There is, however, something so strange in this idea of the absolute value
of the mere will, in which no account is taken of its utility, that
notwithstanding the thorough assent of even common reason to the idea, yet
a suspicion must arise that it may perhaps really be the product of mere
high-flown fancy, and that we may have misunderstood the purpose of nature
in assigning reason as the governor of our will. Therefore we will examine
this idea from this point of view.</p>
<p>In the physical constitution of an organized being, that is, a being
adapted suitably to the purposes of life, we assume it as a fundamental
principle that no organ for any purpose will be found but what is also the
fittest and best adapted for that purpose. Now in a being which has reason
and a will, if the proper object of nature were its conservation, its
welfare, in a word, its happiness, then nature would have hit upon a very
bad arrangement in selecting the reason of the creature to carry out this
purpose. For all the actions which the creature has to perform with a view
to this purpose, and the whole rule of its conduct, would be far more
surely prescribed to it by instinct, and that end would have been attained
thereby much more certainly than it ever can be by reason. Should reason
have been communicated to this favoured creature over and above, it must
only have served it to contemplate the happy constitution of its nature,
to admire it, to congratulate itself thereon, and to feel thankful for it
to the beneficent cause, but not that it should subject its desires to
that weak and delusive guidance and meddle bunglingly with the purpose of
nature. In a word, nature would have taken care that reason should not
break forth into practical exercise, nor have the presumption, with its
weak insight, to think out for itself the plan of happiness, and of the
means of attaining it. Nature would not only have taken on herself the
choice of the ends, but also of the means, and with wise foresight would
have entrusted both to instinct.</p>
<p>And, in fact, we find that the more a cultivated reason applies itself
with deliberate purpose to the enjoyment of life and happiness, so much
the more does the man fail of true satisfaction. And from this
circumstance there arises in many, if they are candid enough to confess
it, a certain degree of misology, that is, hatred of reason, especially in
the case of those who are most experienced in the use of it, because after
calculating all the advantages they derive, I do not say from the
invention of all the arts of common luxury, but even from the sciences
(which seem to them to be after all only a luxury of the understanding),
they find that they have, in fact, only brought more trouble on their
shoulders, rather than gained in happiness; and they end by envying,
rather than despising, the more common stamp of men who keep closer to the
guidance of mere instinct and do not allow their reason much influence on
their conduct. And this we must admit, that the judgement of those who
would very much lower the lofty eulogies of the advantages which reason
gives us in regard to the happiness and satisfaction of life, or who would
even reduce them below zero, is by no means morose or ungrateful to the
goodness with which the world is governed, but that there lies at the root
of these judgements the idea that our existence has a different and far
nobler end, for which, and not for happiness, reason is properly intended,
and which must, therefore, be regarded as the supreme condition to which
the private ends of man must, for the most part, be postponed.</p>
<p>For as reason is not competent to guide the will with certainty in regard
to its objects and the satisfaction of all our wants (which it to some
extent even multiplies), this being an end to which an implanted instinct
would have led with much greater certainty; and since, nevertheless,
reason is imparted to us as a practical faculty, i.e., as one which is to
have influence on the will, therefore, admitting that nature generally in
the distribution of her capacities has adapted the means to the end, its
true destination must be to produce a will, not merely good as a means to
something else, but good in itself, for which reason was absolutely
necessary. This will then, though not indeed the sole and complete good,
must be the supreme good and the condition of every other, even of the
desire of happiness. Under these circumstances, there is nothing
inconsistent with the wisdom of nature in the fact that the cultivation of
the reason, which is requisite for the first and unconditional purpose,
does in many ways interfere, at least in this life, with the attainment of
the second, which is always conditional, namely, happiness. Nay, it may
even reduce it to nothing, without nature thereby failing of her purpose.
For reason recognizes the establishment of a good will as its highest
practical destination, and in attaining this purpose is capable only of a
satisfaction of its own proper kind, namely that from the attainment of an
end, which end again is determined by reason only, notwithstanding that
this may involve many a disappointment to the ends of inclination.</p>
<p>We have then to develop the notion of a will which deserves to be highly
esteemed for itself and is good without a view to anything further, a
notion which exists already in the sound natural understanding, requiring
rather to be cleared up than to be taught, and which in estimating the
value of our actions always takes the first place and constitutes the
condition of all the rest. In order to do this, we will take the notion of
duty, which includes that of a good will, although implying certain
subjective restrictions and hindrances. These, however, far from
concealing it, or rendering it unrecognizable, rather bring it out by
contrast and make it shine forth so much the brighter.</p>
<p>I omit here all actions which are already recognized as inconsistent with
duty, although they may be useful for this or that purpose, for with these
the question whether they are done from duty cannot arise at all, since
they even conflict with it. I also set aside those actions which really
conform to duty, but to which men have no direct inclination, performing
them because they are impelled thereto by some other inclination. For in
this case we can readily distinguish whether the action which agrees with
duty is done from duty, or from a selfish view. It is much harder to make
this distinction when the action accords with duty and the subject has
besides a direct inclination to it. For example, it is always a matter of
duty that a dealer should not over charge an inexperienced purchaser; and
wherever there is much commerce the prudent tradesman does not overcharge,
but keeps a fixed price for everyone, so that a child buys of him as well
as any other. Men are thus honestly served; but this is not enough to make
us believe that the tradesman has so acted from duty and from principles
of honesty: his own advantage required it; it is out of the question in
this case to suppose that he might besides have a direct inclination in
favour of the buyers, so that, as it were, from love he should give no
advantage to one over another. Accordingly the action was done neither
from duty nor from direct inclination, but merely with a selfish view.</p>
<p>On the other hand, it is a duty to maintain one's life; and, in addition,
everyone has also a direct inclination to do so. But on this account the
often anxious care which most men take for it has no intrinsic worth, and
their maxim has no moral import. They preserve their life as duty
requires, no doubt, but not because duty requires. On the other hand, if
adversity and hopeless sorrow have completely taken away the relish for
life; if the unfortunate one, strong in mind, indignant at his fate rather
than desponding or dejected, wishes for death, and yet preserves his life
without loving it- not from inclination or fear, but from duty- then his
maxim has a moral worth.</p>
<p>To be beneficent when we can is a duty; and besides this, there are many
minds so sympathetically constituted that, without any other motive of
vanity or self-interest, they find a pleasure in spreading joy around them
and can take delight in the satisfaction of others so far as it is their
own work. But I maintain that in such a case an action of this kind,
however proper, however amiable it may be, has nevertheless no true moral
worth, but is on a level with other inclinations, e.g., the inclination to
honour, which, if it is happily directed to that which is in fact of
public utility and accordant with duty and consequently honourable,
deserves praise and encouragement, but not esteem. For the maxim lacks the
moral import, namely, that such actions be done from duty, not from
inclination. Put the case that the mind of that philanthropist were
clouded by sorrow of his own, extinguishing all sympathy with the lot of
others, and that, while he still has the power to benefit others in
distress, he is not touched by their trouble because he is absorbed with
his own; and now suppose that he tears himself out of this dead
insensibility, and performs the action without any inclination to it, but
simply from duty, then first has his action its genuine moral worth.
Further still; if nature has put little sympathy in the heart of this or
that man; if he, supposed to be an upright man, is by temperament cold and
indifferent to the sufferings of others, perhaps because in respect of his
own he is provided with the special gift of patience and fortitude and
supposes, or even requires, that others should have the same- and such a
man would certainly not be the meanest product of nature- but if nature
had not specially framed him for a philanthropist, would he not still find
in himself a source from whence to give himself a far higher worth than
that of a good-natured temperament could be? Unquestionably. It is just in
this that the moral worth of the character is brought out which is
incomparably the highest of all, namely, that he is beneficent, not from
inclination, but from duty.</p>
<p>To secure one's own happiness is a duty, at least indirectly; for
discontent with one's condition, under a pressure of many anxieties and
amidst unsatisfied wants, might easily become a great temptation to
transgression of duty. But here again, without looking to duty, all men
have already the strongest and most intimate inclination to happiness,
because it is just in this idea that all inclinations are combined in one
total. But the precept of happiness is often of such a sort that it
greatly interferes with some inclinations, and yet a man cannot form any
definite and certain conception of the sum of satisfaction of all of them
which is called happiness. It is not then to be wondered at that a single
inclination, definite both as to what it promises and as to the time
within which it can be gratified, is often able to overcome such a
fluctuating idea, and that a gouty patient, for instance, can choose to
enjoy what he likes, and to suffer what he may, since, according to his
calculation, on this occasion at least, he has not sacrificed the
enjoyment of the present moment to a possibly mistaken expectation of a
happiness which is supposed to be found in health. But even in this case,
if the general desire for happiness did not influence his will, and
supposing that in his particular case health was not a necessary element
in this calculation, there yet remains in this, as in all other cases,
this law, namely, that he should promote his happiness not from
inclination but from duty, and by this would his conduct first acquire
true moral worth.</p>
<p>It is in this manner, undoubtedly, that we are to understand those
passages of Scripture also in which we are commanded to love our
neighbour, even our enemy. For love, as an affection, cannot be commanded,
but beneficence for duty's sake may; even though we are not impelled to it
by any inclination- nay, are even repelled by a natural and unconquerable
aversion. This is practical love and not pathological- a love which is
seated in the will, and not in the propensions of sense- in principles of
action and not of tender sympathy; and it is this love alone which can be
commanded.</p>
<p>The second proposition is: That an action done from duty derives its moral
worth, not from the purpose which is to be attained by it, but from the
maxim by which it is determined, and therefore does not depend on the
realization of the object of the action, but merely on the principle of
volition by which the action has taken place, without regard to any object
of desire. It is clear from what precedes that the purposes which we may
have in view in our actions, or their effects regarded as ends and springs
of the will, cannot give to actions any unconditional or moral worth. In
what, then, can their worth lie, if it is not to consist in the will and
in reference to its expected effect? It cannot lie anywhere but in the
principle of the will without regard to the ends which can be attained by
the action. For the will stands between its a priori principle, which is
formal, and its a posteriori spring, which is material, as between two
roads, and as it must be determined by something, it follows that it must
be determined by the formal principle of volition when an action is done
from duty, in which case every material principle has been withdrawn from
it.</p>
<p>The third proposition, which is a consequence of the two preceding, I
would express thus: Duty is the necessity of acting from respect for the
law. I may have inclination for an object as the effect of my proposed
action, but I cannot have respect for it, just for this reason, that it is
an effect and not an energy of will. Similarly I cannot have respect for
inclination, whether my own or another's; I can at most, if my own,
approve it; if another's, sometimes even love it; i.e., look on it as
favourable to my own interest. It is only what is connected with my will
as a principle, by no means as an effect- what does not subserve my
inclination, but overpowers it, or at least in case of choice excludes it
from its calculation- in other words, simply the law of itself, which can
be an object of respect, and hence a command. Now an action done from duty
must wholly exclude the influence of inclination and with it every object
of the will, so that nothing remains which can determine the will except
objectively the law, and subjectively pure respect for this practical law,
and consequently the maxim * that I should follow this law even to the
thwarting of all my inclinations.</p>
<p>* A maxim is the subjective principle of volition. The<br/>
objective principle (i.e., that which would also serve<br/>
subjectively as a practical principle to all rational beings<br/>
if reason had full power over the faculty of desire) is the<br/>
practical law.<br/></p>
<p>Thus the moral worth of an action does not lie in the effect expected from
it, nor in any principle of action which requires to borrow its motive
from this expected effect. For all these effects- agreeableness of one's
condition and even the promotion of the happiness of others- could have
been also brought about by other causes, so that for this there would have
been no need of the will of a rational being; whereas it is in this alone
that the supreme and unconditional good can be found. The pre-eminent good
which we call moral can therefore consist in nothing else than the
conception of law in itself, which certainly is only possible in a
rational being, in so far as this conception, and not the expected effect,
determines the will. This is a good which is already present in the person
who acts accordingly, and we have not to wait for it to appear first in
the result. *</p>
<p>* It might be here objected to me that I take refuge behind<br/>
the word respect in an obscure feeling, instead of giving a<br/>
distinct solution of the question by a concept of the<br/>
reason. But although respect is a feeling, it is not a<br/>
feeling received through influence, but is self-wrought by a<br/>
rational concept, and, therefore, is specifically distinct<br/>
from all feelings of the former kind, which may be referred<br/>
either to inclination or fear, What I recognise immediately<br/>
as a law for me, I recognise with respect. This merely<br/>
signifies the consciousness that my will is subordinate to a<br/>
law, without the intervention of other influences on my<br/>
sense. The immediate determination of the will by the law,<br/>
and the consciousness of this, is called respect, so that<br/>
this is regarded as an effect of the law on the subject, and<br/>
not as the cause of it. Respect is properly the conception<br/>
of a worth which thwarts my self-love. Accordingly it is<br/>
something which is considered neither as an object of<br/>
inclination nor of fear, although it has something analogous<br/>
to both. The object of respect is the law only, and that the<br/>
law which we impose on ourselves and yet recognise as<br/>
necessary in itself. As a law, we are subjected too it<br/>
without consulting self-love; as imposed by us on ourselves,<br/>
it is a result of our will. In the former aspect it has an<br/>
analogy to fear, in the latter to inclination. Respect for a<br/>
person is properly only respect for the law (of honesty,<br/>
etc.) of which he gives us an example. Since we also look on<br/>
the improvement of our talents as a duty, we consider that<br/>
we see in a person of talents, as it were, the example of a<br/>
law (viz., to become like him in this by exercise), and this<br/>
constitutes our respect. All so-called moral interest<br/>
consists simply in respect for the law.<br/></p>
<p>But what sort of law can that be, the conception of which must determine
the will, even without paying any regard to the effect expected from it,
in order that this will may be called good absolutely and without
qualification? As I have deprived the will of every impulse which could
arise to it from obedience to any law, there remains nothing but the
universal conformity of its actions to law in general, which alone is to
serve the will as a principle, i.e., I am never to act otherwise than so
that I could also will that my maxim should become a universal law. Here,
now, it is the simple conformity to law in general, without assuming any
particular law applicable to certain actions, that serves the will as its
principle and must so serve it, if duty is not to be a vain delusion and a
chimerical notion. The common reason of men in its practical judgements
perfectly coincides with this and always has in view the principle here
suggested. Let the question be, for example: May I when in distress make a
promise with the intention not to keep it? I readily distinguish here
between the two significations which the question may have: Whether it is
prudent, or whether it is right, to make a false promise? The former may
undoubtedly often be the case. I see clearly indeed that it is not enough
to extricate myself from a present difficulty by means of this subterfuge,
but it must be well considered whether there may not hereafter spring from
this lie much greater inconvenience than that from which I now free
myself, and as, with all my supposed cunning, the consequences cannot be
so easily foreseen but that credit once lost may be much more injurious to
me than any mischief which I seek to avoid at present, it should be
considered whether it would not be more prudent to act herein according to
a universal maxim and to make it a habit to promise nothing except with
the intention of keeping it. But it is soon clear to me that such a maxim
will still only be based on the fear of consequences. Now it is a wholly
different thing to be truthful from duty and to be so from apprehension of
injurious consequences. In the first case, the very notion of the action
already implies a law for me; in the second case, I must first look about
elsewhere to see what results may be combined with it which would affect
myself. For to deviate from the principle of duty is beyond all doubt
wicked; but to be unfaithful to my maxim of prudence may often be very
advantageous to me, although to abide by it is certainly safer. The
shortest way, however, and an unerring one, to discover the answer to this
question whether a lying promise is consistent with duty, is to ask
myself, "Should I be content that my maxim (to extricate myself from
difficulty by a false promise) should hold good as a universal law, for
myself as well as for others?" and should I be able to say to myself,
"Every one may make a deceitful promise when he finds himself in a
difficulty from which he cannot otherwise extricate himself?" Then I
presently become aware that while I can will the lie, I can by no means
will that lying should be a universal law. For with such a law there would
be no promises at all, since it would be in vain to allege my intention in
regard to my future actions to those who would not believe this
allegation, or if they over hastily did so would pay me back in my own
coin. Hence my maxim, as soon as it should be made a universal law, would
necessarily destroy itself.</p>
<p>I do not, therefore, need any far-reaching penetration to discern what I
have to do in order that my will may be morally good. Inexperienced in the
course of the world, incapable of being prepared for all its
contingencies, I only ask myself: Canst thou also will that thy maxim
should be a universal law? If not, then it must be rejected, and that not
because of a disadvantage accruing from it to myself or even to others,
but because it cannot enter as a principle into a possible universal
legislation, and reason extorts from me immediate respect for such
legislation. I do not indeed as yet discern on what this respect is based
(this the philosopher may inquire), but at least I understand this, that
it is an estimation of the worth which far outweighs all worth of what is
recommended by inclination, and that the necessity of acting from pure
respect for the practical law is what constitutes duty, to which every
other motive must give place, because it is the condition of a will being
good in itself, and the worth of such a will is above everything.</p>
<p>Thus, then, without quitting the moral knowledge of common human reason,
we have arrived at its principle. And although, no doubt, common men do
not conceive it in such an abstract and universal form, yet they always
have it really before their eyes and use it as the standard of their
decision. Here it would be easy to show how, with this compass in hand,
men are well able to distinguish, in every case that occurs, what is good,
what bad, conformably to duty or inconsistent with it, if, without in the
least teaching them anything new, we only, like Socrates, direct their
attention to the principle they themselves employ; and that, therefore, we
do not need science and philosophy to know what we should do to be honest
and good, yea, even wise and virtuous. Indeed we might well have
conjectured beforehand that the knowledge of what every man is bound to
do, and therefore also to know, would be within the reach of every man,
even the commonest. Here we cannot forbear admiration when we see how
great an advantage the practical judgement has over the theoretical in the
common understanding of men. In the latter, if common reason ventures to
depart from the laws of experience and from the perceptions of the senses,
it falls into mere inconceivabilities and self-contradictions, at least
into a chaos of uncertainty, obscurity, and instability. But in the
practical sphere it is just when the common understanding excludes all
sensible springs from practical laws that its power of judgement begins to
show itself to advantage. It then becomes even subtle, whether it be that
it chicanes with its own conscience or with other claims respecting what
is to be called right, or whether it desires for its own instruction to
determine honestly the worth of actions; and, in the latter case, it may
even have as good a hope of hitting the mark as any philosopher whatever
can promise himself. Nay, it is almost more sure of doing so, because the
philosopher cannot have any other principle, while he may easily perplex
his judgement by a multitude of considerations foreign to the matter, and
so turn aside from the right way. Would it not therefore be wiser in moral
concerns to acquiesce in the judgement of common reason, or at most only
to call in philosophy for the purpose of rendering the system of morals
more complete and intelligible, and its rules more convenient for use
(especially for disputation), but not so as to draw off the common
understanding from its happy simplicity, or to bring it by means of
philosophy into a new path of inquiry and instruction?</p>
<p>Innocence is indeed a glorious thing; only, on the other hand, it is very
sad that it cannot well maintain itself and is easily seduced. On this
account even wisdom- which otherwise consists more in conduct than in
knowledge- yet has need of science, not in order to learn from it, but to
secure for its precepts admission and permanence. Against all the commands
of duty which reason represents to man as so deserving of respect, he
feels in himself a powerful counterpoise in his wants and inclinations,
the entire satisfaction of which he sums up under the name of happiness.
Now reason issues its commands unyieldingly, without promising anything to
the inclinations, and, as it were, with disregard and contempt for these
claims, which are so impetuous, and at the same time so plausible, and
which will not allow themselves to be suppressed by any command. Hence
there arises a natural dialectic, i.e., a disposition, to argue against
these strict laws of duty and to question their validity, or at least
their purity and strictness; and, if possible, to make them more accordant
with our wishes and inclinations, that is to say, to corrupt them at their
very source, and entirely to destroy their worth- a thing which even
common practical reason cannot ultimately call good.</p>
<p>Thus is the common reason of man compelled to go out of its sphere, and to
take a step into the field of a practical philosophy, not to satisfy any
speculative want (which never occurs to it as long as it is content to be
mere sound reason), but even on practical grounds, in order to attain in
it information and clear instruction respecting the source of its
principle, and the correct determination of it in opposition to the maxims
which are based on wants and inclinations, so that it may escape from the
perplexity of opposite claims and not run the risk of losing all genuine
moral principles through the equivocation into which it easily falls.
Thus, when practical reason cultivates itself, there insensibly arises in
it a dialetic which forces it to seek aid in philosophy, just as happens
to it in its theoretic use; and in this case, therefore, as well as in the
other, it will find rest nowhere but in a thorough critical examination of
our reason.</p>

<br/>
<h2> SECOND SECTION—TRANSITION FROM POPULAR MORAL PHILOSOPHY TO THE METAPHYSIC OF MORALS </h2>
<p>If we have hitherto drawn our notion of duty from the common use of our
practical reason, it is by no means to be inferred that we have treated it
as an empirical notion. On the contrary, if we attend to the experience of
men's conduct, we meet frequent and, as we ourselves allow, just
complaints that one cannot find a single certain example of the
disposition to act from pure duty. Although many things are done in
conformity with what duty prescribes, it is nevertheless always doubtful
whether they are done strictly from duty, so as to have a moral worth.
Hence there have at all times been philosophers who have altogether denied
that this disposition actually exists at all in human actions, and have
ascribed everything to a more or less refined self-love. Not that they
have on that account questioned the soundness of the conception of
morality; on the contrary, they spoke with sincere regret of the frailty
and corruption of human nature, which, though noble enough to take its
rule an idea so worthy of respect, is yet weak to follow it and employs
reason which ought to give it the law only for the purpose of providing
for the interest of the inclinations, whether singly or at the best in the
greatest possible harmony with one another.</p>
<p>In fact, it is absolutely impossible to make out by experience with
complete certainty a single case in which the maxim of an action, however
right in itself, rested simply on moral grounds and on the conception of
duty. Sometimes it happens that with the sharpest self-examination we can
find nothing beside the moral principle of duty which could have been
powerful enough to move us to this or that action and to so great a
sacrifice; yet we cannot from this infer with certainty that it was not
really some secret impulse of self-love, under the false appearance of
duty, that was the actual determining cause of the will. We like them to
flatter ourselves by falsely taking credit for a more noble motive;
whereas in fact we can never, even by the strictest examination, get
completely behind the secret springs of action; since, when the question
is of moral worth, it is not with the actions which we see that we are
concerned, but with those inward principles of them which we do not see.</p>
<p>Moreover, we cannot better serve the wishes of those who ridicule all
morality as a mere chimera of human imagination over stepping itself from
vanity, than by conceding to them that notions of duty must be drawn only
from experience (as from indolence, people are ready to think is also the
case with all other notions); for or is to prepare for them a certain
triumph. I am willing to admit out of love of humanity that even most of
our actions are correct, but if we look closer at them we everywhere come
upon the dear self which is always prominent, and it is this they have in
view and not the strict command of duty which would often require
self-denial. Without being an enemy of virtue, a cool observer, one that
does not mistake the wish for good, however lively, for its reality, may
sometimes doubt whether true virtue is actually found anywhere in the
world, and this especially as years increase and the judgement is partly
made wiser by experience and partly, also, more acute in observation. This
being so, nothing can secure us from falling away altogether from our
ideas of duty, or maintain in the soul a well-grounded respect for its
law, but the clear conviction that although there should never have been
actions which really sprang from such pure sources, yet whether this or
that takes place is not at all the question; but that reason of itself,
independent on all experience, ordains what ought to take place, that
accordingly actions of which perhaps the world has hitherto never given an
example, the feasibility even of which might be very much doubted by one
who founds everything on experience, are nevertheless inflexibly commanded
by reason; that, e.g., even though there might never yet have been a
sincere friend, yet not a whit the less is pure sincerity in friendship
required of every man, because, prior to all experience, this duty is
involved as duty in the idea of a reason determining the will by a priori
principles.</p>
<p>When we add further that, unless we deny that the notion of morality has
any truth or reference to any possible object, we must admit that its law
must be valid, not merely for men but for all rational creatures
generally, not merely under certain contingent conditions or with
exceptions but with absolute necessity, then it is clear that no
experience could enable us to infer even the possibility of such
apodeictic laws. For with what right could we bring into unbounded respect
as a universal precept for every rational nature that which perhaps holds
only under the contingent conditions of humanity? Or how could laws of the
determination of our will be regarded as laws of the determination of the
will of rational beings generally, and for us only as such, if they were
merely empirical and did not take their origin wholly a priori from pure
but practical reason?</p>
<p>Nor could anything be more fatal to morality than that we should wish to
derive it from examples. For every example of it that is set before me
must be first itself tested by principles of morality, whether it is
worthy to serve as an original example, i.e., as a pattern; but by no
means can it authoritatively furnish the conception of morality. Even the
Holy One of the Gospels must first be compared with our ideal of moral
perfection before we can recognise Him as such; and so He says of Himself,
"Why call ye Me (whom you see) good; none is good (the model of good) but
God only (whom ye do not see)?" But whence have we the conception of God
as the supreme good? Simply from the idea of moral perfection, which
reason frames a priori and connects inseparably with the notion of a free
will. Imitation finds no place at all in morality, and examples serve only
for encouragement, i.e., they put beyond doubt the feasibility of what the
law commands, they make visible that which the practical rule expresses
more generally, but they can never authorize us to set aside the true
original which lies in reason and to guide ourselves by examples.</p>
<p>If then there is no genuine supreme principle of morality but what must
rest simply on pure reason, independent of all experience, I think it is
not necessary even to put the question whether it is good to exhibit these
concepts in their generality (in abstracto) as they are established a
priori along with the principles belonging to them, if our knowledge is to
be distinguished from the vulgar and to be called philosophical.</p>
<p>In our times indeed this might perhaps be necessary; for if we collected
votes whether pure rational knowledge separated from everything empirical,
that is to say, metaphysic of morals, or whether popular practical
philosophy is to be preferred, it is easy to guess which side would
preponderate.</p>
<p>This descending to popular notions is certainly very commendable, if the
ascent to the principles of pure reason has first taken place and been
satisfactorily accomplished. This implies that we first found ethics on
metaphysics, and then, when it is firmly established, procure a hearing
for it by giving it a popular character. But it is quite absurd to try to
be popular in the first inquiry, on which the soundness of the principles
depends. It is not only that this proceeding can never lay claim to the
very rare merit of a true philosophical popularity, since there is no art
in being intelligible if one renounces all thoroughness of insight; but
also it produces a disgusting medley of compiled observations and
half-reasoned principles. Shallow pates enjoy this because it can be used
for every-day chat, but the sagacious find in it only confusion, and being
unsatisfied and unable to help themselves, they turn away their eyes,
while philosophers, who see quite well through this delusion, are little
listened to when they call men off for a time from this pretended
popularity, in order that they might be rightfully popular after they have
attained a definite insight.</p>
<p>We need only look at the attempts of moralists in that favourite fashion,
and we shall find at one time the special constitution of human nature
(including, however, the idea of a rational nature generally), at one time
perfection, at another happiness, here moral sense, there fear of God. a
little of this, and a little of that, in marvellous mixture, without its
occurring to them to ask whether the principles of morality are to be
sought in the knowledge of human nature at all (which we can have only
from experience); or, if this is not so, if these principles are to be
found altogether a priori, free from everything empirical, in pure
rational concepts only and nowhere else, not even in the smallest degree;
then rather to adopt the method of making this a separate inquiry, as pure
practical philosophy, or (if one may use a name so decried) as metaphysic
of morals, * to bring it by itself to completeness, and to require the
public, which wishes for popular treatment, to await the issue of this
undertaking.</p>
<p>* Just as pure mathematics are distinguished from applied,<br/>
pure logic from applied, so if we choose we may also<br/>
distinguish pure philosophy of morals (metaphysic) from<br/>
applied (viz., applied to human nature). By this designation<br/>
we are also at once reminded that moral principles are not<br/>
based on properties of human nature, but must subsist a<br/>
priori of themselves, while from such principles practical<br/>
rules must be capable of being deduced for every rational<br/>
nature, and accordingly for that of man.<br/></p>
<p>Such a metaphysic of morals, completely isolated, not mixed with any
anthropology, theology, physics, or hyperphysics, and still less with
occult qualities (which we might call hypophysical), is not only an
indispensable substratum of all sound theoretical knowledge of duties, but
is at the same time a desideratum of the highest importance to the actual
fulfilment of their precepts. For the pure conception of duty, unmixed
with any foreign addition of empirical attractions, and, in a word, the
conception of the moral law, exercises on the human heart, by way of
reason alone (which first becomes aware with this that it can of itself be
practical), an influence so much more powerful than all other springs *
which may be derived from the field of experience, that, in the
consciousness of its worth, it despises the latter, and can by degrees
become their master; whereas a mixed ethics, compounded partly of motives
drawn from feelings and inclinations, and partly also of conceptions of
reason, must make the mind waver between motives which cannot be brought
under any principle, which lead to good only by mere accident and very
often also to evil.</p>
<p>* I have a letter from the late excellent Sulzer, in which<br/>
he asks me what can be the reason that moral instruction,<br/>
although containing much that is convincing for the reason,<br/>
yet accomplishes so little? My answer was postponed in order<br/>
that I might make it complete. But it is simply this: that<br/>
the teachers themselves have not got their own notions<br/>
clear, and when they endeavour to make up for this by raking<br/>
up motives of moral goodness from every quarter, trying to<br/>
make their physic right strong, they spoil it. For the<br/>
commonest understanding shows that if we imagine, on the one<br/>
hand, an act of honesty done with steadfast mind, apart from<br/>
every view to advantage of any kind in this world or<br/>
another, and even under the greatest temptations of<br/>
necessity or allurement, and, on the other hand, a similar<br/>
act which was affected, in however low a degree, by a<br/>
foreign motive, the former leaves far behind and eclipses<br/>
the second; it elevates the soul and inspires the wish to be<br/>
able to act in like manner oneself. Even moderately young<br/>
children feel this impression, ana one should never<br/>
represent duties to them in any other light.<br/></p>
<p>From what has been said, it is clear that all moral conceptions have their
seat and origin completely a priori in the reason, and that, moreover, in
the commonest reason just as truly as in that which is in the highest
degree speculative; that they cannot be obtained by abstraction from any
empirical, and therefore merely contingent, knowledge; that it is just
this purity of their origin that makes them worthy to serve as our supreme
practical principle, and that just in proportion as we add anything
empirical, we detract from their genuine influence and from the absolute
value of actions; that it is not only of the greatest necessity, in a
purely speculative point of view, but is also of the greatest practical
importance, to derive these notions and laws from pure reason, to present
them pure and unmixed, and even to determine the compass of this practical
or pure rational knowledge, i.e., to determine the whole faculty of pure
practical reason; and, in doing so, we must not make its principles
dependent on the particular nature of human reason, though in speculative
philosophy this may be permitted, or may even at times be necessary; but
since moral laws ought to hold good for every rational creature, we must
derive them from the general concept of a rational being. In this way,
although for its application to man morality has need of anthropology,
yet, in the first instance, we must treat it independently as pure
philosophy, i.e., as metaphysic, complete in itself (a thing which in such
distinct branches of science is easily done); knowing well that unless we
are in possession of this, it would not only be vain to determine the
moral element of duty in right actions for purposes of speculative
criticism, but it would be impossible to base morals on their genuine
principles, even for common practical purposes, especially of moral
instruction, so as to produce pure moral dispositions, and to engraft them
on men's minds to the promotion of the greatest possible good in the
world.</p>
<p>But in order that in this study we may not merely advance by the natural
steps from the common moral judgement (in this case very worthy of
respect) to the philosophical, as has been already done, but also from a
popular philosophy, which goes no further than it can reach by groping
with the help of examples, to metaphysic (which does allow itself to be
checked by anything empirical and, as it must measure the whole extent of
this kind of rational knowledge, goes as far as ideal conceptions, where
even examples fail us), we must follow and clearly describe the practical
faculty of reason, from the general rules of its determination to the
point where the notion of duty springs from it.</p>
<p>Everything in nature works according to laws. Rational beings alone have
the faculty of acting according to the conception of laws, that is
according to principles, i.e., have a will. Since the deduction of actions
from principles requires reason, the will is nothing but practical reason.
If reason infallibly determines the will, then the actions of such a being
which are recognised as objectively necessary are subjectively necessary
also, i.e., the will is a faculty to choose that only which reason
independent of inclination recognises as practically necessary, i.e., as
good. But if reason of itself does not sufficiently determine the will, if
the latter is subject also to subjective conditions (particular impulses)
which do not always coincide with the objective conditions; in a word, if
the will does not in itself completely accord with reason (which is
actually the case with men), then the actions which objectively are
recognised as necessary are subjectively contingent, and the determination
of such a will according to objective laws is obligation, that is to say,
the relation of the objective laws to a will that is not thoroughly good
is conceived as the determination of the will of a rational being by
principles of reason, but which the will from its nature does not of
necessity follow.</p>
<p>The conception of an objective principle, in so far as it is obligatory
for a will, is called a command (of reason), and the formula of the
command is called an imperative.</p>
<p>All imperatives are expressed by the word ought [or shall], and thereby
indicate the relation of an objective law of reason to a will, which from
its subjective constitution is not necessarily determined by it (an
obligation). They say that something would be good to do or to forbear,
but they say it to a will which does not always do a thing because it is
conceived to be good to do it. That is practically good, however, which
determines the will by means of the conceptions of reason, and
consequently not from subjective causes, but objectively, that is on
principles which are valid for every rational being as such. It is
distinguished from the pleasant, as that which influences the will only by
means of sensation from merely subjective causes, valid only for the sense
of this or that one, and not as a principle of reason, which holds for
every one. *</p>
<p>* The dependence of the desires on sensations is called<br/>
inclination, and this accordingly always indicates a want.<br/>
The dependence of a contingently determinable will on<br/>
principles of reason is called an interest. This therefore,<br/>
is found only in the case of a dependent will which does not<br/>
always of itself conform to reason; in the Divine will we<br/>
cannot conceive any interest. But the human will can also<br/>
take an interest in a thing without therefore acting from<br/>
interest. The former signifies the practical interest in the<br/>
action, the latter the pathological in the object of the<br/>
action. The former indicates only dependence of the will on<br/>
principles of reason in themselves; the second, dependence<br/>
on principles of reason for the sake of inclination, reason<br/>
supplying only the practical rules how the requirement of<br/>
the inclination may be satisfied. In the first case the<br/>
action interests me; in the second the object of the action<br/>
(because it is pleasant to me). We have seen in the first<br/>
section that in an action done from duty we must look not to<br/>
the interest in the object, but only to that in the action<br/>
itself, and in its rational principle (viz., the law).<br/></p>
<p>A perfectly good will would therefore be equally subject to objective laws
(viz., laws of good), but could not be conceived as obliged thereby to act
lawfully, because of itself from its subjective constitution it can only
be determined by the conception of good. Therefore no imperatives hold for
the Divine will, or in general for a holy will; ought is here out of
place, because the volition is already of itself necessarily in unison
with the law. Therefore imperatives are only formulae to express the
relation of objective laws of all volition to the subjective imperfection
of the will of this or that rational being, e.g., the human will.</p>
<p>Now all imperatives command either hypothetically or categorically. The
former represent the practical necessity of a possible action as means to
something else that is willed (or at least which one might possibly will).
The categorical imperative would be that which represented an action as
necessary of itself without reference to another end, i.e., as objectively
necessary.</p>
<p>Since every practical law represents a possible action as good and, on
this account, for a subject who is practically determinable by reason,
necessary, all imperatives are formulae determining an action which is
necessary according to the principle of a will good in some respects. If
now the action is good only as a means to something else, then the
imperative is hypothetical; if it is conceived as good in itself and
consequently as being necessarily the principle of a will which of itself
conforms to reason, then it is categorical.</p>
<p>Thus the imperative declares what action possible by me would be good and
presents the practical rule in relation to a will which does not forthwith
perform an action simply because it is good, whether because the subject
does not always know that it is good, or because, even if it know this,
yet its maxims might be opposed to the objective principles of practical
reason.</p>
<p>Accordingly the hypothetical imperative only says that the action is good
for some purpose, possible or actual. In the first case it is a
problematical, in the second an assertorial practical principle. The
categorical imperative which declares an action to be objectively
necessary in itself without reference to any purpose, i.e., without any
other end, is valid as an apodeictic (practical) principle.</p>
<p>Whatever is possible only by the power of some rational being may also be
conceived as a possible purpose of some will; and therefore the principles
of action as regards the means necessary to attain some possible purpose
are in fact infinitely numerous. All sciences have a practical part,
consisting of problems expressing that some end is possible for us and of
imperatives directing how it may be attained. These may, therefore, be
called in general imperatives of skill. Here there is no question whether
the end is rational and good, but only what one must do in order to attain
it. The precepts for the physician to make his patient thoroughly healthy,
and for a poisoner to ensure certain death, are of equal value in this
respect, that each serves to effect its purpose perfectly. Since in early
youth it cannot be known what ends are likely to occur to us in the course
of life, parents seek to have their children taught a great many things,
and provide for their skill in the use of means for all sorts of arbitrary
ends, of none of which can they determine whether it may not perhaps
hereafter be an object to their pupil, but which it is at all events
possible that he might aim at; and this anxiety is so great that they
commonly neglect to form and correct their judgement on the value of the
things which may be chosen as ends.</p>
<p>There is one end, however, which may be assumed to be actually such to all
rational beings (so far as imperatives apply to them, viz., as dependent
beings), and, therefore, one purpose which they not merely may have, but
which we may with certainty assume that they all actually have by a
natural necessity, and this is happiness. The hypothetical imperative
which expresses the practical necessity of an action as means to the
advancement of happiness is assertorial. We are not to present it as
necessary for an uncertain and merely possible purpose, but for a purpose
which we may presuppose with certainty and a priori in every man, because
it belongs to his being. Now skill in the choice of means to his own
greatest well-being may be called prudence, * in the narrowest sense. And
thus the imperative which refers to the choice of means to one's own
happiness, i.e., the precept of prudence, is still always hypothetical;
the action is not commanded absolutely, but only as means to another
purpose.</p>
<p>* The word prudence is taken in two senses: in the one it<br/>
may bear the name of knowledge of the world, in the other<br/>
that of private prudence. The former is a man's ability to<br/>
influence others so as to use them for his own purposes. The<br/>
latter is the sagacity to combine all these purposes for his<br/>
own lasting benefit. This latter is properly that to which<br/>
the value even of the former is reduced, and when a man is<br/>
prudent in the former sense, but not in the latter, we might<br/>
better say of him that he is clever and cunning, but, on the<br/>
whole, imprudent.<br/></p>
<p>Finally, there is an imperative which commands a certain conduct
immediately, without having as its condition any other purpose to be
attained by it. This imperative is categorical. It concerns not the matter
of the action, or its intended result, but its form and the principle of
which it is itself a result; and what is essentially good in it consists
in the mental disposition, let the consequence be what it may. This
imperative may be called that of morality.</p>
<p>There is a marked distinction also between the volitions on these three
sorts of principles in the dissimilarity of the obligation of the will. In
order to mark this difference more clearly, I think they would be most
suitably named in their order if we said they are either rules of skill,
or counsels of prudence, or commands (laws) of morality. For it is law
only that involves the conception of an unconditional and objective
necessity, which is consequently universally valid; and commands are laws
which must be obeyed, that is, must be followed, even in opposition to
inclination. Counsels, indeed, involve necessity, but one which can only
hold under a contingent subjective condition, viz., they depend on whether
this or that man reckons this or that as part of his happiness; the
categorical imperative, on the contrary, is not limited by any condition,
and as being absolutely, although practically, necessary, may be quite
properly called a command. We might also call the first kind of
imperatives technical (belonging to art), the second pragmatic * (to
welfare), the third moral (belonging to free conduct generally, that is,
to morals).</p>
<p>* It seems to me that the proper signification of the word<br/>
pragmatic may be most accurately defined in this way. For<br/>
sanctions are called pragmatic which flow properly not from<br/>
the law of the states as necessary enactments, but from<br/>
precaution for the general welfare. A history is composed<br/>
pragmatically when it teaches prudence, i.e., instructs the<br/>
world how it can provide for its interests better, or at<br/>
least as well as, the men of former time.<br/></p>
<p>Now arises the question, how are all these imperatives possible? This
question does not seek to know how we can conceive the accomplishment of
the action which the imperative ordains, but merely how we can conceive
the obligation of the will which the imperative expresses. No special
explanation is needed to show how an imperative of skill is possible.
Whoever wills the end, wills also (so far as reason decides his conduct)
the means in his power which are indispensably necessary thereto. This
proposition is, as regards the volition, analytical; for, in willing an
object as my effect, there is already thought the causality of myself as
an acting cause, that is to say, the use of the means; and the imperative
educes from the conception of volition of an end the conception of actions
necessary to this end. Synthetical propositions must no doubt be employed
in defining the means to a proposed end; but they do not concern the
principle, the act of the will, but the object and its realization. E.g.,
that in order to bisect a line on an unerring principle I must draw from
its extremities two intersecting arcs; this no doubt is taught by
mathematics only in synthetical propositions; but if I know that it is
only by this process that the intended operation can be performed, then to
say that, if I fully will the operation, I also will the action required
for it, is an analytical proposition; for it is one and the same thing to
conceive something as an effect which I can produce in a certain way, and
to conceive myself as acting in this way.</p>
<p>If it were only equally easy to give a definite conception of happiness,
the imperatives of prudence would correspond exactly with those of skill,
and would likewise be analytical. For in this case as in that, it could be
said: "Whoever wills the end, wills also (according to the dictate of
reason necessarily) the indispensable means thereto which are in his
power." But, unfortunately, the notion of happiness is so indefinite that
although every man wishes to attain it, yet he never can say definitely
and consistently what it is that he really wishes and wills. The reason of
this is that all the elements which belong to the notion of happiness are
altogether empirical, i.e., they must be borrowed from experience, and
nevertheless the idea of happiness requires an absolute whole, a maximum
of welfare in my present and all future circumstances. Now it is
impossible that the most clear-sighted and at the same time most powerful
being (supposed finite) should frame to himself a definite conception of
what he really wills in this. Does he will riches, how much anxiety, envy,
and snares might he not thereby draw upon his shoulders? Does he will
knowledge and discernment, perhaps it might prove to be only an eye so
much the sharper to show him so much the more fearfully the evils that are
now concealed from him, and that cannot be avoided, or to impose more
wants on his desires, which already give him concern enough. Would he have
long life? who guarantees to him that it would not be a long misery? would
he at least have health? how often has uneasiness of the body restrained
from excesses into which perfect health would have allowed one to fall?
and so on. In short, he is unable, on any principle, to determine with
certainty what would make him truly happy; because to do so he would need
to be omniscient. We cannot therefore act on any definite principles to
secure happiness, but only on empirical counsels, e.g. of regimen,
frugality, courtesy, reserve, etc., which experience teaches do, on the
average, most promote well-being. Hence it follows that the imperatives of
prudence do not, strictly speaking, command at all, that is, they cannot
present actions objectively as practically necessary; that they are rather
to be regarded as counsels (consilia) than precepts precepts of reason,
that the problem to determine certainly and universally what action would
promote the happiness of a rational being is completely insoluble, and
consequently no imperative respecting it is possible which should, in the
strict sense, command to do what makes happy; because happiness is not an
ideal of reason but of imagination, resting solely on empirical grounds,
and it is vain to expect that these should define an action by which one
could attain the totality of a series of consequences which is really
endless. This imperative of prudence would however be an analytical
proposition if we assume that the means to happiness could be certainly
assigned; for it is distinguished from the imperative of skill only by
this, that in the latter the end is merely possible, in the former it is
given; as however both only ordain the means to that which we suppose to
be willed as an end, it follows that the imperative which ordains the
willing of the means to him who wills the end is in both cases analytical.
Thus there is no difficulty in regard to the possibility of an imperative
of this kind either.</p>
<p>On the other hand, the question how the imperative of morality is
possible, is undoubtedly one, the only one, demanding a solution, as this
is not at all hypothetical, and the objective necessity which it presents
cannot rest on any hypothesis, as is the case with the hypothetical
imperatives. Only here we must never leave out of consideration that we
cannot make out by any example, in other words empirically, whether there
is such an imperative at all, but it is rather to be feared that all those
which seem to be categorical may yet be at bottom hypothetical. For
instance, when the precept is: "Thou shalt not promise deceitfully"; and
it is assumed that the necessity of this is not a mere counsel to avoid
some other evil, so that it should mean: "Thou shalt not make a lying
promise, lest if it become known thou shouldst destroy thy credit," but
that an action of this kind must be regarded as evil in itself, so that
the imperative of the prohibition is categorical; then we cannot show with
certainty in any example that the will was determined merely by the law,
without any other spring of action, although it may appear to be so. For
it is always possible that fear of disgrace, perhaps also obscure dread of
other dangers, may have a secret influence on the will. Who can prove by
experience the non-existence of a cause when all that experience tells us
is that we do not perceive it? But in such a case the so-called moral
imperative, which as such appears to be categorical and unconditional,
would in reality be only a pragmatic precept, drawing our attention to our
own interests and merely teaching us to take these into consideration.</p>
<p>We shall therefore have to investigate a priori the possibility of a
categorical imperative, as we have not in this case the advantage of its
reality being given in experience, so that [the elucidation of] its
possibility should be requisite only for its explanation, not for its
establishment. In the meantime it may be discerned beforehand that the
categorical imperative alone has the purport of a practical law; all the
rest may indeed be called principles of the will but not laws, since
whatever is only necessary for the attainment of some arbitrary purpose
may be considered as in itself contingent, and we can at any time be free
from the precept if we give up the purpose; on the contrary, the
unconditional command leaves the will no liberty to choose the opposite;
consequently it alone carries with it that necessity which we require in a
law.</p>
<p>Secondly, in the case of this categorical imperative or law of morality,
the difficulty (of discerning its possibility) is a very profound one. It
is an a priori synthetical practical proposition; * and as there is so
much difficulty in discerning the possibility of speculative propositions
of this kind, it may readily be supposed that the difficulty will be no
less with the practical.</p>
<p>* I connect the act with the will without presupposing any<br/>
condition resulting from any inclination, but a priori, and<br/>
therefore necessarily (though only objectively, i.e.,<br/>
assuming the idea of a reason possessing full power over all<br/>
subjective motives). This is accordingly a practical<br/>
proposition which does not deduce the willing of an action<br/>
by mere analysis from another already presupposed (for we<br/>
have not such a perfect will), but connects it immediately<br/>
with the conception of the will of a rational being, as<br/>
something not contained in it.<br/></p>
<p>In this problem we will first inquire whether the mere conception of a
categorical imperative may not perhaps supply us also with the formula of
it, containing the proposition which alone can be a categorical
imperative; for even if we know the tenor of such an absolute command, yet
how it is possible will require further special and laborious study, which
we postpone to the last section.</p>
<p>When I conceive a hypothetical imperative, in general I do not know
beforehand what it will contain until I am given the condition. But when I
conceive a categorical imperative, I know at once what it contains. For as
the imperative contains besides the law only the necessity that the maxims
* shall conform to this law, while the law contains no conditions
restricting it, there remains nothing but the general statement that the
maxim of the action should conform to a universal law, and it is this
conformity alone that the imperative properly represents as necessary.</p>
<p>* A maxim is a subjective principle of action, and must be<br/>
distinguished from the objective principle, namely,<br/>
practical law. The former contains the practical rule set by<br/>
reason according to the conditions of the subject (often its<br/>
ignorance or its inclinations), so that it is the principle<br/>
on which the subject acts; but the law is the objective<br/>
principle valid for every rational being, and is the<br/>
principle on which it ought to act that is an imperative.<br/></p>
<p>There is therefore but one categorical imperative, namely, this: Act only
on that maxim whereby thou canst at the same time will that it should
become a universal law.</p>
<p>Now if all imperatives of duty can be deduced from this one imperative as
from their principle, then, although it should remain undecided what is
called duty is not merely a vain notion, yet at least we shall be able to
show what we understand by it and what this notion means.</p>
<p>Since the universality of the law according to which effects are produced
constitutes what is properly called nature in the most general sense (as
to form), that is the existence of things so far as it is determined by
general laws, the imperative of duty may be expressed thus: Act as if the
maxim of thy action were to become by thy will a universal law of nature.</p>
<p>We will now enumerate a few duties, adopting the usual division of them
into duties to ourselves and ourselves and to others, and into perfect and
imperfect duties. *</p>
<p>* It must be noted here that I reserve the division of<br/>
duties for a future metaphysic of morals; so that I give it<br/>
here only as an arbitrary one (in order to arrange my<br/>
examples). For the rest, I understand by a perfect duty one<br/>
that admits no exception in favour of inclination and then I<br/>
have not merely external but also internal perfect duties.<br/>
This is contrary to the use of the word adopted in the<br/>
schools; but I do not intend to justify there, as it is all<br/>
one for my purpose whether it is admitted or not.<br/></p>
<p>1. A man reduced to despair by a series of misfortunes feels wearied of
life, but is still so far in possession of his reason that he can ask
himself whether it would not be contrary to his duty to himself to take
his own life. Now he inquires whether the maxim of his action could become
a universal law of nature. His maxim is: "From self-love I adopt it as a
principle to shorten my life when its longer duration is likely to bring
more evil than satisfaction." It is asked then simply whether this
principle founded on self-love can become a universal law of nature. Now
we see at once that a system of nature of which it should be a law to
destroy life by means of the very feeling whose special nature it is to
impel to the improvement of life would contradict itself and, therefore,
could not exist as a system of nature; hence that maxim cannot possibly
exist as a universal law of nature and, consequently, would be wholly
inconsistent with the supreme principle of all duty.</p>
<p>2. Another finds himself forced by necessity to borrow money. He knows
that he will not be able to repay it, but sees also that nothing will be
lent to him unless he promises stoutly to repay it in a definite time. He
desires to make this promise, but he has still so much conscience as to
ask himself: "Is it not unlawful and inconsistent with duty to get out of
a difficulty in this way?" Suppose however that he resolves to do so: then
the maxim of his action would be expressed thus: "When I think myself in
want of money, I will borrow money and promise to repay it, although I
know that I never can do so." Now this principle of self-love or of one's
own advantage may perhaps be consistent with my whole future welfare; but
the question now is, "Is it right?" I change then the suggestion of
self-love into a universal law, and state the question thus: "How would it
be if my maxim were a universal law?" Then I see at once that it could
never hold as a universal law of nature, but would necessarily contradict
itself. For supposing it to be a universal law that everyone when he
thinks himself in a difficulty should be able to promise whatever he
pleases, with the purpose of not keeping his promise, the promise itself
would become impossible, as well as the end that one might have in view in
it, since no one would consider that anything was promised to him, but
would ridicule all such statements as vain pretences.</p>
<p>3. A third finds in himself a talent which with the help of some culture
might make him a useful man in many respects. But he finds himself in
comfortable circumstances and prefers to indulge in pleasure rather than
to take pains in enlarging and improving his happy natural capacities. He
asks, however, whether his maxim of neglect of his natural gifts, besides
agreeing with his inclination to indulgence, agrees also with what is
called duty. He sees then that a system of nature could indeed subsist
with such a universal law although men (like the South Sea islanders)
should let their talents rest and resolve to devote their lives merely to
idleness, amusement, and propagation of their species- in a word, to
enjoyment; but he cannot possibly will that this should be a universal law
of nature, or be implanted in us as such by a natural instinct. For, as a
rational being, he necessarily wills that his faculties be developed,
since they serve him and have been given him, for all sorts of possible
purposes.</p>
<p>4. A fourth, who is in prosperity, while he sees that others have to
contend with great wretchedness and that he could help them, thinks: "What
concern is it of mine? Let everyone be as happy as Heaven pleases, or as
he can make himself; I will take nothing from him nor even envy him, only
I do not wish to contribute anything to his welfare or to his assistance
in distress!" Now no doubt if such a mode of thinking were a universal
law, the human race might very well subsist and doubtless even better than
in a state in which everyone talks of sympathy and good-will, or even
takes care occasionally to put it into practice, but, on the other side,
also cheats when he can, betrays the rights of men, or otherwise violates
them. But although it is possible that a universal law of nature might
exist in accordance with that maxim, it is impossible to will that such a
principle should have the universal validity of a law of nature. For a
will which resolved this would contradict itself, inasmuch as many cases
might occur in which one would have need of the love and sympathy of
others, and in which, by such a law of nature, sprung from his own will,
he would deprive himself of all hope of the aid he desires.</p>
<p>These are a few of the many actual duties, or at least what we regard as
such, which obviously fall into two classes on the one principle that we
have laid down. We must be able to will that a maxim of our action should
be a universal law. This is the canon of the moral appreciation of the
action generally. Some actions are of such a character that their maxim
cannot without contradiction be even conceived as a universal law of
nature, far from it being possible that we should will that it should be
so. In others this intrinsic impossibility is not found, but still it is
impossible to will that their maxim should be raised to the universality
of a law of nature, since such a will would contradict itself It is easily
seen that the former violate strict or rigorous (inflexible) duty; the
latter only laxer (meritorious) duty. Thus it has been completely shown
how all duties depend as regards the nature of the obligation (not the
object of the action) on the same principle.</p>
<p>If now we attend to ourselves on occasion of any transgression of duty, we
shall find that we in fact do not will that our maxim should be a
universal law, for that is impossible for us; on the contrary, we will
that the opposite should remain a universal law, only we assume the
liberty of making an exception in our own favour or (just for this time
only) in favour of our inclination. Consequently if we considered all
cases from one and the same point of view, namely, that of reason, we
should find a contradiction in our own will, namely, that a certain
principle should be objectively necessary as a universal law, and yet
subjectively should not be universal, but admit of exceptions. As however
we at one moment regard our action from the point of view of a will wholly
conformed to reason, and then again look at the same action from the point
of view of a will affected by inclination, there is not really any
contradiction, but an antagonism of inclination to the precept of reason,
whereby the universality of the principle is changed into a mere
generality, so that the practical principle of reason shall meet the maxim
half way. Now, although this cannot be justified in our own impartial
judgement, yet it proves that we do really recognise the validity of the
categorical imperative and (with all respect for it) only allow ourselves
a few exceptions, which we think unimportant and forced from us.</p>
<p>We have thus established at least this much, that if duty is a conception
which is to have any import and real legislative authority for our
actions, it can only be expressed in categorical and not at all in
hypothetical imperatives. We have also, which is of great importance,
exhibited clearly and definitely for every practical application the
content of the categorical imperative, which must contain the principle of
all duty if there is such a thing at all. We have not yet, however,
advanced so far as to prove a priori that there actually is such an
imperative, that there is a practical law which commands absolutely of
itself and without any other impulse, and that the following of this law
is duty.</p>
<p>With the view of attaining to this, it is of extreme importance to
remember that we must not allow ourselves to think of deducing the reality
of this principle from the particular attributes of human nature. For duty
is to be a practical, unconditional necessity of action; it must therefore
hold for all rational beings (to whom an imperative can apply at all), and
for this reason only be also a law for all human wills. On the contrary,
whatever is deduced from the particular natural characteristics of
humanity, from certain feelings and propensions, nay, even, if possible,
from any particular tendency proper to human reason, and which need not
necessarily hold for the will of every rational being; this may indeed
supply us with a maxim, but not with a law; with a subjective principle on
which we may have a propension and inclination to act, but not with an
objective principle on which we should be enjoined to act, even though all
our propensions, inclinations, and natural dispositions were opposed to
it. In fact, the sublimity and intrinsic dignity of the command in duty
are so much the more evident, the less the subjective impulses favour it
and the more they oppose it, without being able in the slightest degree to
weaken the obligation of the law or to diminish its validity.</p>
<p>Here then we see philosophy brought to a critical position, since it has
to be firmly fixed, notwithstanding that it has nothing to support it in
heaven or earth. Here it must show its purity as absolute director of its
own laws, not the herald of those which are whispered to it by an
implanted sense or who knows what tutelary nature. Although these may be
better than nothing, yet they can never afford principles dictated by
reason, which must have their source wholly a priori and thence their
commanding authority, expecting everything from the supremacy of the law
and the due respect for it, nothing from inclination, or else condemning
the man to self-contempt and inward abhorrence.</p>
<p>Thus every empirical element is not only quite incapable of being an aid
to the principle of morality, but is even highly prejudicial to the purity
of morals, for the proper and inestimable worth of an absolutely good will
consists just in this, that the principle of action is free from all
influence of contingent grounds, which alone experience can furnish. We
cannot too much or too often repeat our warning against this lax and even
mean habit of thought which seeks for its principle amongst empirical
motives and laws; for human reason in its weariness is glad to rest on
this pillow, and in a dream of sweet illusions (in which, instead of Juno,
it embraces a cloud) it substitutes for morality a bastard patched up from
limbs of various derivation, which looks like anything one chooses to see
in it, only not like virtue to one who has once beheld her in her true
form. *</p>
<p>* To behold virtue in her proper form is nothing else but to<br/>
contemplate morality stripped of all admixture of sensible<br/>
things and of every spurious ornament of reward or self-<br/>
love. How much she then eclipses everything else that<br/>
appears charming to the affections, every one may readily<br/>
perceive with the least exertion of his reason, if it be not<br/>
wholly spoiled for abstraction.<br/></p>
<p>The question then is this: "Is it a necessary law for all rational beings
that they should always judge of their actions by maxims of which they can
themselves will that they should serve as universal laws?" If it is so,
then it must be connected (altogether a priori) with the very conception
of the will of a rational being generally. But in order to discover this
connexion we must, however reluctantly, take a step into metaphysic,
although into a domain of it which is distinct from speculative
philosophy, namely, the metaphysic of morals. In a practical philosophy,
where it is not the reasons of what happens that we have to ascertain, but
the laws of what ought to happen, even although it never does, i.e.,
objective practical laws, there it is not necessary to inquire into the
reasons why anything pleases or displeases, how the pleasure of mere
sensation differs from taste, and whether the latter is distinct from a
general satisfaction of reason; on what the feeling of pleasure or pain
rests, and how from it desires and inclinations arise, and from these
again maxims by the co-operation of reason: for all this belongs to an
empirical psychology, which would constitute the second part of physics,
if we regard physics as the philosophy of nature, so far as it is based on
empirical laws. But here we are concerned with objective practical laws
and, consequently, with the relation of the will to itself so far as it is
determined by reason alone, in which case whatever has reference to
anything empirical is necessarily excluded; since if reason of itself
alone determines the conduct (and it is the possibility of this that we
are now investigating), it must necessarily do so a priori.</p>
<p>The will is conceived as a faculty of determining oneself to action in
accordance with the conception of certain laws. And such a faculty can be
found only in rational beings. Now that which serves the will as the
objective ground of its self-determination is the end, and, if this is
assigned by reason alone, it must hold for all rational beings. On the
other hand, that which merely contains the ground of possibility of the
action of which the effect is the end, this is called the means. The
subjective ground of the desire is the spring, the objective ground of the
volition is the motive; hence the distinction between subjective ends
which rest on springs, and objective ends which depend on motives valid
for every rational being. Practical principles are formal when they
abstract from all subjective ends; they are material when they assume
these, and therefore particular springs of action. The ends which a
rational being proposes to himself at pleasure as effects of his actions
(material ends) are all only relative, for it is only their relation to
the particular desires of the subject that gives them their worth, which
therefore cannot furnish principles universal and necessary for all
rational beings and for every volition, that is to say practical laws.
Hence all these relative ends can give rise only to hypothetical
imperatives.</p>
<p>Supposing, however, that there were something whose existence has in
itself an absolute worth, something which, being an end in itself, could
be a source of definite laws; then in this and this alone would lie the
source of a possible categorical imperative, i.e., a practical law.</p>
<p>Now I say: man and generally any rational being exists as an end in
himself, not merely as a means to be arbitrarily used by this or that
will, but in all his actions, whether they concern himself or other
rational beings, must be always regarded at the same time as an end. All
objects of the inclinations have only a conditional worth, for if the
inclinations and the wants founded on them did not exist, then their
object would be without value. But the inclinations, themselves being
sources of want, are so far from having an absolute worth for which they
should be desired that on the contrary it must be the universal wish of
every rational being to be wholly free from them. Thus the worth of any
object which is to be acquired by our action is always conditional. Beings
whose existence depends not on our will but on nature's, have
nevertheless, if they are irrational beings, only a relative value as
means, and are therefore called things; rational beings, on the contrary,
are called persons, because their very nature points them out as ends in
themselves, that is as something which must not be used merely as means,
and so far therefore restricts freedom of action (and is an object of
respect). These, therefore, are not merely subjective ends whose existence
has a worth for us as an effect of our action, but objective ends, that
is, things whose existence is an end in itself; an end moreover for which
no other can be substituted, which they should subserve merely as means,
for otherwise nothing whatever would possess absolute worth; but if all
worth were conditioned and therefore contingent, then there would be no
supreme practical principle of reason whatever.</p>
<p>If then there is a supreme practical principle or, in respect of the human
will, a categorical imperative, it must be one which, being drawn from the
conception of that which is necessarily an end for everyone because it is
an end in itself, constitutes an objective principle of will, and can
therefore serve as a universal practical law. The foundation of this
principle is: rational nature exists as an end in itself. Man necessarily
conceives his own existence as being so; so far then this is a subjective
principle of human actions. But every other rational being regards its
existence similarly, just on the same rational principle that holds for
me: * so that it is at the same time an objective principle, from which as
a supreme practical law all laws of the will must be capable of being
deduced. Accordingly the practical imperative will be as follows: So act
as to treat humanity, whether in thine own person or in that of any other,
in every case as an end withal, never as means only. We will now inquire
whether this can be practically carried out.</p>
<p>* This proposition is here stated as a postulate. The ground<br/>
of it will be found in the concluding section.<br/></p>
<p>To abide by the previous examples:</p>
<p>Firstly, under the head of necessary duty to oneself: He who contemplates
suicide should ask himself whether his action can be consistent with the
idea of humanity as an end in itself. If he destroys himself in order to
escape from painful circumstances, he uses a person merely as a mean to
maintain a tolerable condition up to the end of life. But a man is not a
thing, that is to say, something which can be used merely as means, but
must in all his actions be always considered as an end in himself. I
cannot, therefore, dispose in any way of a man in my own person so as to
mutilate him, to damage or kill him. (It belongs to ethics proper to
define this principle more precisely, so as to avoid all misunderstanding,
e. g., as to the amputation of the limbs in order to preserve myself, as
to exposing my life to danger with a view to preserve it, etc. This
question is therefore omitted here.)</p>
<p>Secondly, as regards necessary duties, or those of strict obligation,
towards others: He who is thinking of making a lying promise to others
will see at once that he would be using another man merely as a mean,
without the latter containing at the same time the end in himself. For he
whom I propose by such a promise to use for my own purposes cannot
possibly assent to my mode of acting towards him and, therefore, cannot
himself contain the end of this action. This violation of the principle of
humanity in other men is more obvious if we take in examples of attacks on
the freedom and property of others. For then it is clear that he who
transgresses the rights of men intends to use the person of others merely
as a means, without considering that as rational beings they ought always
to be esteemed also as ends, that is, as beings who must be capable of
containing in themselves the end of the very same action. *</p>
<p>* Let it not be thought that the common "quod tibi non vis<br/>
fieri, etc." could serve here as the rule or principle. For<br/>
it is only a deduction from the former, though with several<br/>
limitations; it cannot be a universal law, for it does not<br/>
contain the principle of duties to oneself, nor of the<br/>
duties of benevolence to others (for many a one would gladly<br/>
consent that others should not benefit him, provided only<br/>
that he might be excused from showing benevolence to them),<br/>
nor finally that of duties of strict obligation to one<br/>
another, for on this principle the criminal might argue<br/>
against the judge who punishes him, and so on.<br/></p>
<p>Thirdly, as regards contingent (meritorious) duties to oneself: It is not
enough that the action does not violate humanity in our own person as an
end in itself, it must also harmonize with it. Now there are in humanity
capacities of greater perfection, which belong to the end that nature has
in view in regard to humanity in ourselves as the subject: to neglect
these might perhaps be consistent with the maintenance of humanity as an
end in itself, but not with the advancement of this end.</p>
<p>Fourthly, as regards meritorious duties towards others: The natural end
which all men have is their own happiness. Now humanity might indeed
subsist, although no one should contribute anything to the happiness of
others, provided he did not intentionally withdraw anything from it; but
after all this would only harmonize negatively not positively with
humanity as an end in itself, if every one does not also endeavour, as far
as in him lies, to forward the ends of others. For the ends of any subject
which is an end in himself ought as far as possible to be my ends also, if
that conception is to have its full effect with me.</p>
<p>This principle, that humanity and generally every rational nature is an
end in itself (which is the supreme limiting condition of every man's
freedom of action), is not borrowed from experience, firstly, because it
is universal, applying as it does to all rational beings whatever, and
experience is not capable of determining anything about them; secondly,
because it does not present humanity as an end to men (subjectively), that
is as an object which men do of themselves actually adopt as an end; but
as an objective end, which must as a law constitute the supreme limiting
condition of all our subjective ends, let them be what we will; it must
therefore spring from pure reason. In fact the objective principle of all
practical legislation lies (according to the first principle) in the rule
and its form of universality which makes it capable of being a law (say,
e. g., a law of nature); but the subjective principle is in the end; now
by the second principle the subject of all ends is each rational being,
inasmuch as it is an end in itself. Hence follows the third practical
principle of the will, which is the ultimate condition of its harmony with
universal practical reason, viz.: the idea of the will of every rational
being as a universally legislative will.</p>
<p>On this principle all maxims are rejected which are inconsistent with the
will being itself universal legislator. Thus the will is not subject
simply to the law, but so subject that it must be regarded as itself
giving the law and, on this ground only, subject to the law (of which it
can regard itself as the author).</p>
<p>In the previous imperatives, namely, that based on the conception of the
conformity of actions to general laws, as in a physical system of nature,
and that based on the universal prerogative of rational beings as ends in
themselves- these imperatives, just because they were conceived as
categorical, excluded from any share in their authority all admixture of
any interest as a spring of action; they were, however, only assumed to be
categorical, because such an assumption was necessary to explain the
conception of duty. But we could not prove independently that there are
practical propositions which command categorically, nor can it be proved
in this section; one thing, however, could be done, namely, to indicate in
the imperative itself, by some determinate expression, that in the case of
volition from duty all interest is renounced, which is the specific
criterion of categorical as distinguished from hypothetical imperatives.
This is done in the present (third) formula of the principle, namely, in
the idea of the will of every rational being as a universally legislating
will.</p>
<p>For although a will which is subject to laws may be attached to this law
by means of an interest, yet a will which is itself a supreme lawgiver so
far as it is such cannot possibly depend on any interest, since a will so
dependent would itself still need another law restricting the interest of
its self-love by the condition that it should be valid as universal law.</p>
<p>Thus the principle that every human will is a will which in all its maxims
gives universal laws, * provided it be otherwise justified, would be very
well adapted to be the categorical imperative, in this respect, namely,
that just because of the idea of universal legislation it is not based on
interest, and therefore it alone among all possible imperatives can be
unconditional. Or still better, converting the proposition, if there is a
categorical imperative (i.e., a law for the will of every rational being),
it can only command that everything be done from maxims of one's will
regarded as a will which could at the same time will that it should itself
give universal laws, for in that case only the practical principle and the
imperative which it obeys are unconditional, since they cannot be based on
any interest.</p>
<p>* I may be excused from adducing examples to elucidate this<br/>
principle, as those which have already been used to<br/>
elucidate the categorical imperative and its formula would<br/>
all serve for the like purpose here.<br/></p>
<p>Looking back now on all previous attempts to discover the principle of
morality, we need not wonder why they all failed. It was seen that man was
bound to laws by duty, but it was not observed that the laws to which he
is subject are only those of his own giving, though at the same time they
are universal, and that he is only bound to act in conformity with his own
will; a will, however, which is designed by nature to give universal laws.
For when one has conceived man only as subject to a law (no matter what),
then this law required some interest, either by way of attraction or
constraint, since it did not originate as a law from his own will, but
this will was according to a law obliged by something else to act in a
certain manner. Now by this necessary consequence all the labour spent in
finding a supreme principle of duty was irrevocably lost. For men never
elicited duty, but only a necessity of acting from a certain interest.
Whether this interest was private or otherwise, in any case the imperative
must be conditional and could not by any means be capable of being a moral
command. I will therefore call this the principle of autonomy of the will,
in contrast with every other which I accordingly reckon as heteronomy.</p>
<p>The conception of the will of every rational being as one which must
consider itself as giving in all the maxims of its will universal laws, so
as to judge itself and its actions from this point of view- this
conception leads to another which depends on it and is very fruitful,
namely that of a kingdom of ends.</p>
<p>By a kingdom I understand the union of different rational beings in a
system by common laws. Now since it is by laws that ends are determined as
regards their universal validity, hence, if we abstract from the personal
differences of rational beings and likewise from all the content of their
private ends, we shall be able to conceive all ends combined in a
systematic whole (including both rational beings as ends in themselves,
and also the special ends which each may propose to himself), that is to
say, we can conceive a kingdom of ends, which on the preceding principles
is possible.</p>
<p>For all rational beings come under the law that each of them must treat
itself and all others never merely as means, but in every case at the same
time as ends in themselves. Hence results a systematic union of rational
being by common objective laws, i.e., a kingdom which may be called a
kingdom of ends, since what these laws have in view is just the relation
of these beings to one another as ends and means. It is certainly only an
ideal.</p>
<p>A rational being belongs as a member to the kingdom of ends when, although
giving universal laws in it, he is also himself subject to these laws. He
belongs to it as sovereign when, while giving laws, he is not subject to
the will of any other.</p>
<p>A rational being must always regard himself as giving laws either as
member or as sovereign in a kingdom of ends which is rendered possible by
the freedom of will. He cannot, however, maintain the latter position
merely by the maxims of his will, but only in case he is a completely
independent being without wants and with unrestricted power adequate to
his will.</p>
<p>Morality consists then in the reference of all action to the legislation
which alone can render a kingdom of ends possible. This legislation must
be capable of existing in every rational being and of emanating from his
will, so that the principle of this will is never to act on any maxim
which could not without contradiction be also a universal law and,
accordingly, always so to act that the will could at the same time regard
itself as giving in its maxims universal laws. If now the maxims of
rational beings are not by their own nature coincident with this objective
principle, then the necessity of acting on it is called practical
necessitation, i.e., duty. Duty does not apply to the sovereign in the
kingdom of ends, but it does to every member of it and to all in the same
degree.</p>
<p>The practical necessity of acting on this principle, i.e., duty, does not
rest at all on feelings, impulses, or inclinations, but solely on the
relation of rational beings to one another, a relation in which the will
of a rational being must always be regarded as legislative, since
otherwise it could not be conceived as an end in itself. Reason then
refers every maxim of the will, regarding it as legislating universally,
to every other will and also to every action towards oneself; and this not
on account of any other practical motive or any future advantage, but from
the idea of the dignity of a rational being, obeying no law but that which
he himself also gives.</p>
<p>In the kingdom of ends everything has either value or dignity. Whatever
has a value can be replaced by something else which is equivalent;
whatever, on the other hand, is above all value, and therefore admits of
no equivalent, has a dignity.</p>
<p>Whatever has reference to the general inclinations and wants of mankind
has a market value; whatever, without presupposing a want, corresponds to
a certain taste, that is to a satisfaction in the mere purposeless play of
our faculties, has a fancy value; but that which constitutes the condition
under which alone anything can be an end in itself, this has not merely a
relative worth, i.e., value, but an intrinsic worth, that is, dignity.</p>
<p>Now morality is the condition under which alone a rational being can be an
end in himself, since by this alone is it possible that he should be a
legislating member in the kingdom of ends. Thus morality, and humanity as
capable of it, is that which alone has dignity. Skill and diligence in
labour have a market value; wit, lively imagination, and humour, have
fancy value; on the other hand, fidelity to promises, benevolence from
principle (not from instinct), have an intrinsic worth. Neither nature nor
art contains anything which in default of these it could put in their
place, for their worth consists not in the effects which spring from them,
not in the use and advantage which they secure, but in the disposition of
mind, that is, the maxims of the will which are ready to manifest
themselves in such actions, even though they should not have the desired
effect. These actions also need no recommendation from any subjective
taste or sentiment, that they may be looked on with immediate favour and
satisfaction: they need no immediate propension or feeling for them; they
exhibit the will that performs them as an object of an immediate respect,
and nothing but reason is required to impose them on the will; not to
flatter it into them, which, in the case of duties, would be a
contradiction. This estimation therefore shows that the worth of such a
disposition is dignity, and places it infinitely above all value, with
which it cannot for a moment be brought into comparison or competition
without as it were violating its sanctity.</p>
<p>What then is it which justifies virtue or the morally good disposition, in
making such lofty claims? It is nothing less than the privilege it secures
to the rational being of participating in the giving of universal laws, by
which it qualifies him to be a member of a possible kingdom of ends, a
privilege to which he was already destined by his own nature as being an
end in himself and, on that account, legislating in the kingdom of ends;
free as regards all laws of physical nature, and obeying those only which
he himself gives, and by which his maxims can belong to a system of
universal law, to which at the same time he submits himself. For nothing
has any worth except what the law assigns it. Now the legislation itself
which assigns the worth of everything must for that very reason possess
dignity, that is an unconditional incomparable worth; and the word respect
alone supplies a becoming expression for the esteem which a rational being
must have for it. Autonomy then is the basis of the dignity of human and
of every rational nature.</p>
<p>The three modes of presenting the principle of morality that have been
adduced are at bottom only so many formulae of the very same law, and each
of itself involves the other two. There is, however, a difference in them,
but it is rather subjectively than objectively practical, intended namely
to bring an idea of the reason nearer to intuition (by means of a certain
analogy) and thereby nearer to feeling. All maxims, in fact, have:</p>
<p>1. A form, consisting in universality; and in this view the formula of the
moral imperative is expressed thus, that the maxims must be so chosen as
if they were to serve as universal laws of nature.</p>
<p>2. A matter, namely, an end, and here the formula says that the rational
being, as it is an end by its own nature and therefore an end in itself,
must in every maxim serve as the condition limiting all merely relative
and arbitrary ends.</p>
<p>3. A complete characterization of all maxims by means of that formula,
namely, that all maxims ought by their own legislation to harmonize with a
possible kingdom of ends as with a kingdom of nature. * There is a
progress here in the order of the categories of unity of the form of the
will (its universality), plurality of the matter (the objects, i.e., the
ends), and totality of the system of these. In forming our moral judgement
of actions, it is better to proceed always on the strict method and start
from the general formula of the categorical imperative: Act according to a
maxim which can at the same time make itself a universal law. If, however,
we wish to gain an entrance for the moral law, it is very useful to bring
one and the same action under the three specified conceptions, and thereby
as far as possible to bring it nearer to intuition.</p>
<p>* Teleology considers nature as a kingdom of ends; ethics<br/>
regards a possible kingdom of ends as a kingdom nature. In<br/>
the first case, the kingdom of ends is a theoretical idea,<br/>
adopted to explain what actually is. In the latter it is a<br/>
practical idea, adopted to bring about that which is not<br/>
yet, but which can be realized by our conduct, namely, if it<br/>
conforms to this idea.<br/></p>
<p>We can now end where we started at the beginning, namely, with the
conception of a will unconditionally good. That will is absolutely good
which cannot be evil- in other words, whose maxim, if made a universal
law, could never contradict itself. This principle, then, is its supreme
law: "Act always on such a maxim as thou canst at the same time will to be
a universal law"; this is the sole condition under which a will can never
contradict itself; and such an imperative is categorical. Since the
validity of the will as a universal law for possible actions is analogous
to the universal connexion of the existence of things by general laws,
which is the formal notion of nature in general, the categorical
imperative can also be expressed thus: Act on maxims which can at the same
time have for their object themselves as universal laws of nature. Such
then is the formula of an absolutely good will.</p>
<p>Rational nature is distinguished from the rest of nature by this, that it
sets before itself an end. This end would be the matter of every good
will. But since in the idea of a will that is absolutely good without
being limited by any condition (of attaining this or that end) we must
abstract wholly from every end to be effected (since this would make every
will only relatively good), it follows that in this case the end must be
conceived, not as an end to be effected, but as an independently existing
end. Consequently it is conceived only negatively, i.e., as that which we
must never act against and which, therefore, must never be regarded merely
as means, but must in every volition be esteemed as an end likewise. Now
this end can be nothing but the subject of all possible ends, since this
is also the subject of a possible absolutely good will; for such a will
cannot without contradiction be postponed to any other object. The
principle: "So act in regard to every rational being (thyself and others),
that he may always have place in thy maxim as an end in himself," is
accordingly essentially identical with this other: "Act upon a maxim
which, at the same time, involves its own universal validity for every
rational being." For that in using means for every end I should limit my
maxim by the condition of its holding good as a law for every subject,
this comes to the same thing as that the fundamental principle of all
maxims of action must be that the subject of all ends, i.e., the rational
being himself, be never employed merely as means, but as the supreme
condition restricting the use of all means, that is in every case as an
end likewise.</p>
<p>It follows incontestably that, to whatever laws any rational being may be
subject, he being an end in himself must be able to regard himself as also
legislating universally in respect of these same laws, since it is just
this fitness of his maxims for universal legislation that distinguishes
him as an end in himself; also it follows that this implies his dignity
(prerogative) above all mere physical beings, that he must always take his
maxims from the point of view which regards himself and, likewise, every
other rational being as law-giving beings (on which account they are
called persons). In this way a world of rational beings (mundus
intelligibilis) is possible as a kingdom of ends, and this by virtue of
the legislation proper to all persons as members. Therefore every rational
being must so act as if he were by his maxims in every case a legislating
member in the universal kingdom of ends. The formal principle of these
maxims is: "So act as if thy maxim were to serve likewise as the universal
law (of all rational beings)." A kingdom of ends is thus only possible on
the analogy of a kingdom of nature, the former however only by maxims,
that is self-imposed rules, the latter only by the laws of efficient
causes acting under necessitation from without. Nevertheless, although the
system of nature is looked upon as a machine, yet so far as it has
reference to rational beings as its ends, it is given on this account the
name of a kingdom of nature. Now such a kingdom of ends would be actually
realized by means of maxims conforming to the canon which the categorical
imperative prescribes to all rational beings, if they were universally
followed. But although a rational being, even if he punctually follows
this maxim himself, cannot reckon upon all others being therefore true to
the same, nor expect that the kingdom of nature and its orderly
arrangements shall be in harmony with him as a fitting member, so as to
form a kingdom of ends to which he himself contributes, that is to say,
that it shall favour his expectation of happiness, still that law: "Act
according to the maxims of a member of a merely possible kingdom of ends
legislating in it universally," remains in its full force, inasmuch as it
commands categorically. And it is just in this that the paradox lies; that
the mere dignity of man as a rational creature, without any other end or
advantage to be attained thereby, in other words, respect for a mere idea,
should yet serve as an inflexible precept of the will, and that it is
precisely in this independence of the maxim on all such springs of action
that its sublimity consists; and it is this that makes every rational
subject worthy to be a legislative member in the kingdom of ends: for
otherwise he would have to be conceived only as subject to the physical
law of his wants. And although we should suppose the kingdom of nature and
the kingdom of ends to be united under one sovereign, so that the latter
kingdom thereby ceased to be a mere idea and acquired true reality, then
it would no doubt gain the accession of a strong spring, but by no means
any increase of its intrinsic worth. For this sole absolute lawgiver must,
notwithstanding this, be always conceived as estimating the worth of
rational beings only by their disinterested behaviour, as prescribed to
themselves from that idea [the dignity of man] alone. The essence of
things is not altered by their external relations, and that which,
abstracting from these, alone constitutes the absolute worth of man, is
also that by which he must be judged, whoever the judge may be, and even
by the Supreme Being. Morality, then, is the relation of actions to the
relation of actions will, that is, to the autonomy of potential universal
legislation by its maxims. An action that is consistent with the autonomy
of the will is permitted; one that does not agree therewith is forbidden.
A will whose maxims necessarily coincide with the laws of autonomy is a
holy will, good absolutely. The dependence of a will not absolutely good
on the principle of autonomy (moral necessitation) is obligation. This,
then, cannot be applied to a holy being. The objective necessity of
actions from obligation is called duty.</p>
<p>From what has just been said, it is easy to see how it happens that,
although the conception of duty implies subjection to the law, we yet
ascribe a certain dignity and sublimity to the person who fulfils all his
duties. There is not, indeed, any sublimity in him, so far as he is
subject to the moral law; but inasmuch as in regard to that very law he is
likewise a legislator, and on that account alone subject to it, he has
sublimity. We have also shown above that neither fear nor inclination, but
simply respect for the law, is the spring which can give actions a moral
worth. Our own will, so far as we suppose it to act only under the
condition that its maxims are potentially universal laws, this ideal will
which is possible to us is the proper object of respect; and the dignity
of humanity consists just in this capacity of being universally
legislative, though with the condition that it is itself subject to this
same legislation.</p>

<h2> The Autonomy of the Will as the Supreme Principle of Morality </h2>
<p>Autonomy of the will is that property of it by which it is a law to itself
(independently of any property of the objects of volition). The principle
of autonomy then is: "Always so to choose that the same volition shall
comprehend the maxims of our choice as a universal law." We cannot prove
that this practical rule is an imperative, i.e., that the will of every
rational being is necessarily bound to it as a condition, by a mere
analysis of the conceptions which occur in it, since it is a synthetical
proposition; we must advance beyond the cognition of the objects to a
critical examination of the subject, that is, of the pure practical
reason, for this synthetic proposition which commands apodeictically must
be capable of being cognized wholly a priori. This matter, however, does
not belong to the present section. But that the principle of autonomy in
question is the sole principle of morals can be readily shown by mere
analysis of the conceptions of morality. For by this analysis we find that
its principle must be a categorical imperative and that what this commands
is neither more nor less than this very autonomy.</p>

<p><SPAN name="link2H_4_0005" id="link2H_4_0005"> </SPAN></p>
<br/>
<h2> Heteronomy of the Will as the Source of all spurious Principles of Morality </h2>
<p>If the will seeks the law which is to determine it anywhere else than in
the fitness of its maxims to be universal laws of its own dictation,
consequently if it goes out of itself and seeks this law in the character
of any of its objects, there always results heteronomy. The will in that
case does not give itself the law, but it is given by the object through
its relation to the will. This relation, whether it rests on inclination
or on conceptions of reason, only admits of hypothetical imperatives: "I
ought to do something because I wish for something else." On the contrary,
the moral, and therefore categorical, imperative says: "I ought to do so
and so, even though I should not wish for anything else." E.g., the former
says: "I ought not to lie, if I would retain my reputation"; the latter
says: "I ought not to lie, although it should not bring me the least
discredit." The latter therefore must so far abstract from all objects
that they shall have no influence on the will, in order that practical
reason (will) may not be restricted to administering an interest not
belonging to it, but may simply show its own commanding authority as the
supreme legislation. Thus, e.g., I ought to endeavour to promote the
happiness of others, not as if its realization involved any concern of
mine (whether by immediate inclination or by any satisfaction indirectly
gained through reason), but simply because a maxim which excludes it
cannot be comprehended as a universal law in one and the same volition.</p>

<br/>
<h2> Classification of all Principles of Morality which can be founded on the Conception of Heteronomy </h2>
<p>Here as elsewhere human reason in its pure use, so long as it was not
critically examined, has first tried all possible wrong ways before it
succeeded in finding the one true way.</p>
<p>All principles which can be taken from this point of view are either
empirical or rational. The former, drawn from the principle of happiness,
are built on physical or moral feelings; the latter, drawn from the
principle of perfection, are built either on the rational conception of
perfection as a possible effect, or on that of an independent perfection
(the will of God) as the determining cause of our will.</p>
<p>Empirical principles are wholly incapable of serving as a foundation for
moral laws. For the universality with which these should hold for all
rational beings without distinction, the unconditional practical necessity
which is thereby imposed on them, is lost when their foundation is taken
from the particular constitution of human nature, or the accidental
circumstances in which it is placed. The principle of private happiness,
however, is the most objectionable, not merely because it is false, and
experience contradicts the supposition that prosperity is always
proportioned to good conduct, nor yet merely because it contributes
nothing to the establishment of morality- since it is quite a different
thing to make a prosperous man and a good man, or to make one prudent and
sharp-sighted for his own interests and to make him virtuous- but because
the springs it provides for morality are such as rather undermine it and
destroy its sublimity, since they put the motives to virtue and to vice in
the same class and only teach us to make a better calculation, the
specific difference between virtue and vice being entirely extinguished.
On the other hand, as to moral feeling, this supposed special sense, * the
appeal to it is indeed superficial when those who cannot think believe
that feeling will help them out, even in what concerns general laws: and
besides, feelings, which naturally differ infinitely in degree, cannot
furnish a uniform standard of good and evil, nor has anyone a right to
form judgements for others by his own feelings: nevertheless this moral
feeling is nearer to morality and its dignity in this respect, that it
pays virtue the honour of ascribing to her immediately the satisfaction
and esteem we have for her and does not, as it were, tell her to her face
that we are not attached to her by her beauty but by profit.</p>
<p>* I class the principle of moral feeling under that of<br/>
happiness, because every empirical interest promises to<br/>
contribute to our well-being by the agreeableness that a<br/>
thing affords, whether it be immediately and without a view<br/>
to profit, or whether profit be regarded. We must likewise,<br/>
with Hutcheson, class the principle of sympathy with the<br/>
happiness of others under his assumed moral sense.<br/></p>
<p>Amongst the rational principles of morality, the ontological conception of
perfection, notwithstanding its defects, is better than the theological
conception which derives morality from a Divine absolutely perfect will.
The former is, no doubt, empty and indefinite and consequently useless for
finding in the boundless field of possible reality the greatest amount
suitable for us; moreover, in attempting to distinguish specifically the
reality of which we are now speaking from every other, it inevitably tends
to turn in a circle and cannot avoid tacitly presupposing the morality
which it is to explain; it is nevertheless preferable to the theological
view, first, because we have no intuition of the divine perfection and can
only deduce it from our own conceptions, the most important of which is
that of morality, and our explanation would thus be involved in a gross
circle; and, in the next place, if we avoid this, the only notion of the
Divine will remaining to us is a conception made up of the attributes of
desire of glory and dominion, combined with the awful conceptions of might
and vengeance, and any system of morals erected on this foundation would
be directly opposed to morality.</p>
<p>However, if I had to choose between the notion of the moral sense and that
of perfection in general (two systems which at least do not weaken
morality, although they are totally incapable of serving as its
foundation), then I should decide for the latter, because it at least
withdraws the decision of the question from the sensibility and brings it
to the court of pure reason; and although even here it decides nothing, it
at all events preserves the indefinite idea (of a will good in itself free
from corruption, until it shall be more precisely defined.</p>
<p>For the rest I think I may be excused here from a detailed refutation of
all these doctrines; that would only be superfluous labour, since it is so
easy, and is probably so well seen even by those whose office requires
them to decide for one of these theories (because their hearers would not
tolerate suspension of judgement). But what interests us more here is to
know that the prime foundation of morality laid down by all these
principles is nothing but heteronomy of the will, and for this reason they
must necessarily miss their aim.</p>
<p>In every case where an object of the will has to be supposed, in order
that the rule may be prescribed which is to determine the will, there the
rule is simply heteronomy; the imperative is conditional, namely, if or
because one wishes for this object, one should act so and so: hence it can
never command morally, that is, categorically. Whether the object
determines the will by means of inclination, as in the principle of
private happiness, or by means of reason directed to objects of our
possible volition generally, as in the principle of perfection, in either
case the will never determines itself immediately by the conception of the
action, but only by the influence which the foreseen effect of the action
has on the will; I ought to do something, on this account, because I wish
for something else; and here there must be yet another law assumed in me
as its subject, by which I necessarily will this other thing, and this law
again requires an imperative to restrict this maxim. For the influence
which the conception of an object within the reach of our faculties can
exercise on the will of the subject, in consequence of its natural
properties, depends on the nature of the subject, either the sensibility
(inclination and taste), or the understanding and reason, the employment
of which is by the peculiar constitution of their nature attended with
satisfaction. It follows that the law would be, properly speaking, given
by nature, and, as such, it must be known and proved by experience and
would consequently be contingent and therefore incapable of being an
apodeictic practical rule, such as the moral rule must be. Not only so,
but it is inevitably only heteronomy; the will does not give itself the
law, but is given by a foreign impulse by means of a particular natural
constitution of the subject adapted to receive it. An absolutely good
will, then, the principle of which must be a categorical imperative, will
be indeterminate as regards all objects and will contain merely the form
of volition generally, and that as autonomy, that is to say, the
capability of the maxims of every good will to make themselves a universal
law, is itself the only law which the will of every rational being imposes
on itself, without needing to assume any spring or interest as a
foundation.</p>
<p>How such a synthetical practical a priori proposition is possible, and why
it is necessary, is a problem whose solution does not lie within the
bounds of the metaphysic of morals; and we have not here affirmed its
truth, much less professed to have a proof of it in our power. We simply
showed by the development of the universally received notion of morality
that an autonomy of the will is inevitably connected with it, or rather is
its foundation. Whoever then holds morality to be anything real, and not a
chimerical idea without any truth, must likewise admit the principle of it
that is here assigned. This section then, like the first, was merely
analytical. Now to prove that morality is no creation of the brain, which
it cannot be if the categorical imperative and with it the autonomy of the
will is true, and as an a priori principle absolutely necessary, this
supposes the possibility of a synthetic use of pure practical reason,
which however we cannot venture on without first giving a critical
examination of this faculty of reason. In the concluding section we shall
give the principal outlines of this critical examination as far as is
sufficient for our purpose.</p>

<h2> The Concept of Freedom is the Key that explains the Autonomy of the Will </h2>
<p>The will is a kind of causality belonging to living beings in so far as
they are rational, and freedom would be this property of such causality
that it can be efficient, independently of foreign causes determining it;
just as physical necessity is the property that the causality of all
irrational beings has of being determined to activity by the influence of
foreign causes.</p>
<p>The preceding definition of freedom is negative and therefore unfruitful
for the discovery of its essence, but it leads to a positive conception
which is so much the more full and fruitful.</p>
<p>Since the conception of causality involves that of laws, according to
which, by something that we call cause, something else, namely the effect,
must be produced; hence, although freedom is not a property of the will
depending on physical laws, yet it is not for that reason lawless; on the
contrary it must be a causality acting according to immutable laws, but of
a peculiar kind; otherwise a free will would be an absurdity. Physical
necessity is a heteronomy of the efficient causes, for every effect is
possible only according to this law, that something else determines the
efficient cause to exert its causality. What else then can freedom of the
will be but autonomy, that is, the property of the will to be a law to
itself? But the proposition: "The will is in every action a law to
itself," only expresses the principle: "To act on no other maxim than that
which can also have as an object itself as a universal law." Now this is
precisely the formula of the categorical imperative and is the principle
of morality, so that a free will and a will subject to moral laws are one
and the same.</p>
<p>On the hypothesis, then, of freedom of the will, morality together with
its principle follows from it by mere analysis of the conception. However,
the latter is a synthetic proposition; viz., an absolutely good will is
that whose maxim can always include itself regarded as a universal law;
for this property of its maxim can never be discovered by analysing the
conception of an absolutely good will. Now such synthetic propositions are
only possible in this way: that the two cognitions are connected together
by their union with a third in which they are both to be found. The
positive concept of freedom furnishes this third cognition, which cannot,
as with physical causes, be the nature of the sensible world (in the
concept of which we find conjoined the concept of something in relation as
cause to something else as effect). We cannot now at once show what this
third is to which freedom points us and of which we have an idea a priori,
nor can we make intelligible how the concept of freedom is shown to be
legitimate from principles of pure practical reason and with it the
possibility of a categorical imperative; but some further preparation is
required.</p>

<h2> Freedom must be presupposed as a Property of the Will of all Rational Beings </h2>
<p>It is not enough to predicate freedom of our own will, from Whatever
reason, if we have not sufficient grounds for predicating the same of all
rational beings. For as morality serves as a law for us only because we
are rational beings, it must also hold for all rational beings; and as it
must be deduced simply from the property of freedom, it must be shown that
freedom also is a property of all rational beings. It is not enough, then,
to prove it from certain supposed experiences of human nature (which
indeed is quite impossible, and it can only be shown a priori), but we
must show that it belongs to the activity of all rational beings endowed
with a will. Now I say every being that cannot act except under the idea
of freedom is just for that reason in a practical point of view really
free, that is to say, all laws which are inseparably connected with
freedom have the same force for him as if his will had been shown to be
free in itself by a proof theoretically conclusive. * Now I affirm that we
must attribute to every rational being which has a will that it has also
the idea of freedom and acts entirely under this idea. For in such a being
we conceive a reason that is practical, that is, has causality in
reference to its objects. Now we cannot possibly conceive a reason
consciously receiving a bias from any other quarter with respect to its
judgements, for then the subject would ascribe the determination of its
judgement not to its own reason, but to an impulse. It must regard itself
as the author of its principles independent of foreign influences.
Consequently as practical reason or as the will of a rational being it
must regard itself as free, that is to say, the will of such a being
cannot be a will of its own except under the idea of freedom. This idea
must therefore in a practical point of view be ascribed to every rational
being.</p>
<p>* I adopt this method of assuming freedom merely as an idea<br/>
which rational beings suppose in their actions, in order to<br/>
avoid the necessity of proving it in its theoretical aspect<br/>
also. The former is sufficient for my purpose; for even<br/>
though the speculative proof should not be made out, yet a<br/>
being that cannot act except with the idea of freedom is<br/>
bound by the same laws that would oblige a being who was<br/>
actually free. Thus we can escape here from the onus which<br/>
presses on the theory.<br/></p>

<h2> Of the Interest attaching to the Ideas of Morality </h2>
<p>We have finally reduced the definite conception of morality to the idea of
freedom. This latter, however, we could not prove to be actually a
property of ourselves or of human nature; only we saw that it must be
presupposed if we would conceive a being as rational and conscious of its
causality in respect of its actions, i.e., as endowed with a will; and so
we find that on just the same grounds we must ascribe to every being
endowed with reason and will this attribute of determining itself to
action under the idea of its freedom.</p>
<p>Now it resulted also from the presupposition of these ideas that we became
aware of a law that the subjective principles of action, i.e., maxims,
must always be so assumed that they can also hold as objective, that is,
universal principles, and so serve as universal laws of our own dictation.
But why then should I subject myself to this principle and that simply as
a rational being, thus also subjecting to it all other being endowed with
reason? I will allow that no interest urges me to this, for that would not
give a categorical imperative, but I must take an interest in it and
discern how this comes to pass; for this properly an "I ought" is properly
an "I would," valid for every rational being, provided only that reason
determined his actions without any hindrance. But for beings that are in
addition affected as we are by springs of a different kind, namely,
sensibility, and in whose case that is not always done which reason alone
would do, for these that necessity is expressed only as an "ought," and
the subjective necessity is different from the objective.</p>
<p>It seems then as if the moral law, that is, the principle of autonomy of
the will, were properly speaking only presupposed in the idea of freedom,
and as if we could not prove its reality and objective necessity
independently. In that case we should still have gained something
considerable by at least determining the true principle more exactly than
had previously been done; but as regards its validity and the practical
necessity of subjecting oneself to it, we should not have advanced a step.
For if we were asked why the universal validity of our maxim as a law must
be the condition restricting our actions, and on what we ground the worth
which we assign to this manner of acting- a worth so great that there
cannot be any higher interest; and if we were asked further how it happens
that it is by this alone a man believes he feels his own personal worth,
in comparison with which that of an agreeable or disagreeable condition is
to be regarded as nothing, to these questions we could give no
satisfactory answer.</p>
<p>We find indeed sometimes that we can take an interest in a personal
quality which does not involve any interest of external condition,
provided this quality makes us capable of participating in the condition
in case reason were to effect the allotment; that is to say, the mere
being worthy of happiness can interest of itself even without the motive
of participating in this happiness. This judgement, however, is in fact
only the effect of the importance of the moral law which we before
presupposed (when by the idea of freedom we detach ourselves from every
empirical interest); but that we ought to detach ourselves from these
interests, i.e., to consider ourselves as free in action and yet as
subject to certain laws, so as to find a worth simply in our own person
which can compensate us for the loss of everything that gives worth to our
condition; this we are not yet able to discern in this way, nor do we see
how it is possible so to act- in other words, whence the moral law derives
its obligation.</p>
<p>It must be freely admitted that there is a sort of circle here from which
it seems impossible to escape. In the order of efficient causes we assume
ourselves free, in order that in the order of ends we may conceive
ourselves as subject to moral laws: and we afterwards conceive ourselves
as subject to these laws, because we have attributed to ourselves freedom
of will: for freedom and self-legislation of will are both autonomy and,
therefore, are reciprocal conceptions, and for this very reason one must
not be used to explain the other or give the reason of it, but at most
only logical purposes to reduce apparently different notions of the same
object to one single concept (as we reduce different fractions of the same
value to the lowest terms).</p>
<p>One resource remains to us, namely, to inquire whether we do not occupy
different points of view when by means of freedom we think ourselves as
causes efficient a priori, and when we form our conception of ourselves
from our actions as effects which we see before our eyes.</p>
<p>It is a remark which needs no subtle reflection to make, but which we may
assume that even the commonest understanding can make, although it be
after its fashion by an obscure discernment of judgement which it calls
feeling, that all the "ideas" that come to us involuntarily (as those of
the senses) do not enable us to know objects otherwise than as they affect
us; so that what they may be in themselves remains unknown to us, and
consequently that as regards "ideas" of this kind even with the closest
attention and clearness that the understanding can apply to them, we can
by them only attain to the knowledge of appearances, never to that of
things in themselves. As soon as this distinction has once been made
(perhaps merely in consequence of the difference observed between the
ideas given us from without, and in which we are passive, and those that
we produce simply from ourselves, and in which we show our own activity),
then it follows of itself that we must admit and assume behind the
appearance something else that is not an appearance, namely, the things in
themselves; although we must admit that as they can never be known to us
except as they affect us, we can come no nearer to them, nor can we ever
know what they are in themselves. This must furnish a distinction, however
crude, between a world of sense and the world of understanding, of which
the former may be different according to the difference of the sensuous
impressions in various observers, while the second which is its basis
always remains the same, Even as to himself, a man cannot pretend to know
what he is in himself from the knowledge he has by internal sensation. For
as he does not as it were create himself, and does not come by the
conception of himself a priori but empirically, it naturally follows that
he can obtain his knowledge even of himself only by the inner sense and,
consequently, only through the appearances of his nature and the way in
which his consciousness is affected. At the same time beyond these
characteristics of his own subject, made up of mere appearances, he must
necessarily suppose something else as their basis, namely, his ego,
whatever its characteristics in itself may be. Thus in respect to mere
perception and receptivity of sensations he must reckon himself as
belonging to the world of sense; but in respect of whatever there may be
of pure activity in him (that which reaches consciousness immediately and
not through affecting the senses), he must reckon himself as belonging to
the intellectual world, of which, however, he has no further knowledge. To
such a conclusion the reflecting man must come with respect to all the
things which can be presented to him: it is probably to be met with even
in persons of the commonest understanding, who, as is well known, are very
much inclined to suppose behind the objects of the senses something else
invisible and acting of itself. They spoil it, however, by presently
sensualizing this invisible again; that is to say, wanting to make it an
object of intuition, so that they do not become a whit the wiser.</p>
<p>Now man really finds in himself a faculty by which he distinguishes
himself from everything else, even from himself as affected by objects,
and that is reason. This being pure spontaneity is even elevated above the
understanding. For although the latter is a spontaneity and does not, like
sense, merely contain intuitions that arise when we are affected by things
(and are therefore passive), yet it cannot produce from its activity any
other conceptions than those which merely serve to bring the intuitions of
sense under rules and, thereby, to unite them in one consciousness, and
without this use of the sensibility it could not think at all; whereas, on
the contrary, reason shows so pure a spontaneity in the case of what I
call ideas [ideal conceptions] that it thereby far transcends everything
that the sensibility can give it, and exhibits its most important function
in distinguishing the world of sense from that of understanding, and
thereby prescribing the limits of the understanding itself.</p>
<p>For this reason a rational being must regard himself qua intelligence (not
from the side of his lower faculties) as belonging not to the world of
sense, but to that of understanding; hence he has two points of view from
which he can regard himself, and recognise laws of the exercise of his
faculties, and consequently of all his actions: first, so far as he
belongs to the world of sense, he finds himself subject to laws of nature
(heteronomy); secondly, as belonging to the intelligible world, under laws
which being independent of nature have their foundation not in experience
but in reason alone.</p>
<p>As a rational being, and consequently belonging to the intelligible world,
man can never conceive the causality of his own will otherwise than on
condition of the idea of freedom, for independence of the determinate
causes of the sensible world (an independence which reason must always
ascribe to itself) is freedom. Now the idea of freedom is inseparably
connected with the conception of autonomy, and this again with the
universal principle of morality which is ideally the foundation of all
actions of rational beings, just as the law of nature is of all phenomena.</p>
<p>Now the suspicion is removed which we raised above, that there was a
latent circle involved in our reasoning from freedom to autonomy, and from
this to the moral law, viz.: that we laid down the idea of freedom because
of the moral law only that we might afterwards in turn infer the latter
from freedom, and that consequently we could assign no reason at all for
this law, but could only [present] it as a petitio principii which well
disposed minds would gladly concede to us, but which we could never put
forward as a provable proposition. For now we see that, when we conceive
ourselves as free, we transfer ourselves into the world of understanding
as members of it and recognise the autonomy of the will with its
consequence, morality; whereas, if we conceive ourselves as under
obligation, we consider ourselves as belonging to the world of sense and
at the same time to the world of understanding.</p>

<h2> How is a Categorical Imperative Possible? </h2>
<p>Every rational being reckons himself qua intelligence as belonging to the
world of understanding, and it is simply as an efficient cause belonging
to that world that he calls his causality a will. On the other side he is
also conscious of himself as a part of the world of sense in which his
actions, which are mere appearances [phenomena] of that causality, are
displayed; we cannot, however, discern how they are possible from this
causality which we do not know; but instead of that, these actions as
belonging to the sensible world must be viewed as determined by other
phenomena, namely, desires and inclinations. If therefore I were only a
member of the world of understanding, then all my actions would perfectly
conform to the principle of autonomy of the pure will; if I were only a
part of the world of sense, they would necessarily be assumed to conform
wholly to the natural law of desires and inclinations, in other words, to
the heteronomy of nature. (The former would rest on morality as the
supreme principle, the latter on happiness.) Since, however, the world of
understanding contains the foundation of the world of sense, and
consequently of its laws also, and accordingly gives the law to my will
(which belongs wholly to the world of understanding) directly, and must be
conceived as doing so, it follows that, although on the one side I must
regard myself as a being belonging to the world of sense, yet on the other
side I must recognize myself as subject as an intelligence to the law of
the world of understanding, i.e., to reason, which contains this law in
the idea of freedom, and therefore as subject to the autonomy of the will:
consequently I must regard the laws of the world of understanding as
imperatives for me and the actions which conform to them as duties.</p>
<p>And thus what makes categorical imperatives possible is this, that the
idea of freedom makes me a member of an intelligible world, in consequence
of which, if I were nothing else, all my actions would always conform to
the autonomy of the will; but as I at the same time intuite myself as a
member of the world of sense, they ought so to conform, and this
categorical "ought" implies a synthetic a priori proposition, inasmuch as
besides my will as affected by sensible desires there is added further the
idea of the same will but as belonging to the world of the understanding,
pure and practical of itself, which contains the supreme condition
according to reason of the former will; precisely as to the intuitions of
sense there are added concepts of the understanding which of themselves
signify nothing but regular form in general and in this way synthetic a
priori propositions become possible, on which all knowledge of physical
nature rests.</p>
<p>The practical use of common human reason confirms this reasoning. There is
no one, not even the most consummate villain, provided only that he is
otherwise accustomed to the use of reason, who, when we set before him
examples of honesty of purpose, of steadfastness in following good maxims,
of sympathy and general benevolence (even combined with great sacrifices
of advantages and comfort), does not wish that he might also possess these
qualities. Only on account of his inclinations and impulses he cannot
attain this in himself, but at the same time he wishes to be free from
such inclinations which are burdensome to himself. He proves by this that
he transfers himself in thought with a will free from the impulses of the
sensibility into an order of things wholly different from that of his
desires in the field of the sensibility; since he cannot expect to obtain
by that wish any gratification of his desires, nor any position which
would satisfy any of his actual or supposable inclinations (for this would
destroy the pre-eminence of the very idea which wrests that wish from
him): he can only expect a greater intrinsic worth of his own person. This
better person, however, he imagines himself to be when be transfers
himself to the point of view of a member of the world of the
understanding, to which he is involuntarily forced by the idea of freedom,
i.e., of independence on determining causes of the world of sense; and
from this point of view he is conscious of a good will, which by his own
confession constitutes the law for the bad will that he possesses as a
member of the world of sense- a law whose authority he recognizes while
transgressing it. What he morally "ought" is then what he necessarily
"would," as a member of the world of the understanding, and is conceived
by him as an "ought" only inasmuch as he likewise considers himself as a
member of the world of sense.</p>

<br/>
<h2> Of the Extreme Limits of all Practical Philosophy. </h2>
<p>All men attribute to themselves freedom of will. Hence come all judgements
upon actions as being such as ought to have been done, although they have
not been done. However, this freedom is not a conception of experience,
nor can it be so, since it still remains, even though experience shows the
contrary of what on supposition of freedom are conceived as its necessary
consequences. On the other side it is equally necessary that everything
that takes place should be fixedly determined according to laws of nature.
This necessity of nature is likewise not an empirical conception, just for
this reason, that it involves the motion of necessity and consequently of
a priori cognition. But this conception of a system of nature is confirmed
by experience; and it must even be inevitably presupposed if experience
itself is to be possible, that is, a connected knowledge of the objects of
sense resting on general laws. Therefore freedom is only an idea of
reason, and its objective reality in itself is doubtful; while nature is a
concept of the understanding which proves, and must necessarily prove, its
reality in examples of experience.</p>
<p>There arises from this a dialectic of reason, since the freedom attributed
to the will appears to contradict the necessity of nature, and placed
between these two ways reason for speculative purposes finds the road of
physical necessity much more beaten and more appropriate than that of
freedom; yet for practical purposes the narrow footpath of freedom is the
only one on which it is possible to make use of reason in our conduct;
hence it is just as impossible for the subtlest philosophy as for the
commonest reason of men to argue away freedom. Philosophy must then assume
that no real contradiction will be found between freedom and physical
necessity of the same human actions, for it cannot give up the conception
of nature any more than that of freedom.</p>
<p>Nevertheless, even though we should never be able to comprehend how
freedom is possible, we must at least remove this apparent contradiction
in a convincing manner. For if the thought of freedom contradicts either
itself or nature, which is equally necessary, it must in competition with
physical necessity be entirely given up.</p>
<p>It would, however, be impossible to escape this contradiction if the
thinking subject, which seems to itself free, conceived itself in the same
sense or in the very same relation when it calls itself free as when in
respect of the same action it assumes itself to be subject to the law of
nature. Hence it is an indispensable problem of speculative philosophy to
show that its illusion respecting the contradiction rests on this, that we
think of man in a different sense and relation when we call him free and
when we regard him as subject to the laws of nature as being part and
parcel of nature. It must therefore show that not only can both these very
well co-exist, but that both must be thought as necessarily united in the
same subject, since otherwise no reason could be given why we should
burden reason with an idea which, though it may possibly without
contradiction be reconciled with another that is sufficiently established,
yet entangles us in a perplexity which sorely embarrasses reason in its
theoretic employment. This duty, however, belongs only to speculative
philosophy. The philosopher then has no option whether he will remove the
apparent contradiction or leave it untouched; for in the latter case the
theory respecting this would be bonum vacans, into the possession of which
the fatalist would have a right to enter and chase all morality out of its
supposed domain as occupying it without title.</p>
<p>We cannot however as yet say that we are touching the bounds of practical
philosophy. For the settlement of that controversy does not belong to it;
it only demands from speculative reason that it should put an end to the
discord in which it entangles itself in theoretical questions, so that
practical reason may have rest and security from external attacks which
might make the ground debatable on which it desires to build.</p>
<p>The claims to freedom of will made even by common reason are founded on
the consciousness and the admitted supposition that reason is independent
of merely subjectively determined causes which together constitute what
belongs to sensation only and which consequently come under the general
designation of sensibility. Man considering himself in this way as an
intelligence places himself thereby in a different order of things and in
a relation to determining grounds of a wholly different kind when on the
one hand he thinks of himself as an intelligence endowed with a will, and
consequently with causality, and when on the other he perceives himself as
a phenomenon in the world of sense (as he really is also), and affirms
that his causality is subject to external determination according to laws
of nature. Now he soon becomes aware that both can hold good, nay, must
hold good at the same time. For there is not the smallest contradiction in
saying that a thing in appearance (belonging to the world of sense) is
subject to certain laws, of which the very same as a thing or being in
itself is independent, and that he must conceive and think of himself in
this twofold way, rests as to the first on the consciousness of himself as
an object affected through the senses, and as to the second on the
consciousness of himself as an intelligence, i.e., as independent on
sensible impressions in the employment of his reason (in other words as
belonging to the world of understanding).</p>
<p>Hence it comes to pass that man claims the possession of a will which
takes no account of anything that comes under the head of desires and
inclinations and, on the contrary, conceives actions as possible to him,
nay, even as necessary which can only be done by disregarding all desires
and sensible inclinations. The causality of such actions lies in him as an
intelligence and in the laws of effects and actions [which depend] on the
principles of an intelligible world, of which indeed he knows nothing more
than that in it pure reason alone independent of sensibility gives the
law; moreover since it is only in that world, as an intelligence, that he
is his proper self (being as man only the appearance of himself), those
laws apply to him directly and categorically, so that the incitements of
inclinations and appetites (in other words the whole nature of the world
of sense) cannot impair the laws of his volition as an intelligence. Nay,
he does not even hold himself responsible for the former or ascribe them
to his proper self, i.e., his will: he only ascribes to his will any
indulgence which he might yield them if he allowed them to influence his
maxims to the prejudice of the rational laws of the will.</p>
<p>When practical reason thinks itself into a world of understanding, it does
not thereby transcend its own limits, as it would if it tried to enter it
by intuition or sensation. The former is only a negative thought in
respect of the world of sense, which does not give any laws to reason in
determining the will and is positive only in this single point that this
freedom as a negative characteristic is at the same time conjoined with a
(positive) faculty and even with a causality of reason, which we designate
a will, namely a faculty of so acting that the principle of the actions
shall conform to the essential character of a rational motive, i.e., the
condition that the maxim have universal validity as a law. But were it to
borrow an object of will, that is, a motive, from the world of
understanding, then it would overstep its bounds and pretend to be
acquainted with something of which it knows nothing. The conception of a
world of the understanding is then only a point of view which reason finds
itself compelled to take outside the appearances in order to conceive
itself as practical, which would not be possible if the influences of the
sensibility had a determining power on man, but which is necessary unless
he is to be denied the consciousness of himself as an intelligence and,
consequently, as a rational cause, energizing by reason, that is,
operating freely. This thought certainly involves the idea of an order and
a system of laws different from that of the mechanism of nature which
belongs to the sensible world; and it makes the conception of an
intelligible world necessary (that is to say, the whole system of rational
beings as things in themselves). But it does not in the least authorize us
to think of it further than as to its formal condition only, that is, the
universality of the maxims of the will as laws, and consequently the
autonomy of the latter, which alone is consistent with its freedom;
whereas, on the contrary, all laws that refer to a definite object give
heteronomy, which only belongs to laws of nature and can only apply to the
sensible world.</p>
<p>But reason would overstep all its bounds if it undertook to explain how
pure reason can be practical, which would be exactly the same problem as
to explain how freedom is possible.</p>
<p>For we can explain nothing but that which we can reduce to laws, the
object of which can be given in some possible experience. But freedom is a
mere idea, the objective reality of which can in no wise be shown
according to laws of nature, and consequently not in any possible
experience; and for this reason it can never be comprehended or
understood, because we cannot support it by any sort of example or
analogy. It holds good only as a necessary hypothesis of reason in a being
that believes itself conscious of a will, that is, of a faculty distinct
from mere desire (namely, a faculty of determining itself to action as an
intelligence, in other words, by laws of reason independently on natural
instincts). Now where determination according to laws of nature ceases,
there all explanation ceases also, and nothing remains but defence, i.e.,
the removal of the objections of those who pretend to have seen deeper
into the nature of things, and thereupon boldly declare freedom
impossible. We can only point out to them that the supposed contradiction
that they have discovered in it arises only from this, that in order to be
able to apply the law of nature to human actions, they must necessarily
consider man as an appearance: then when we demand of them that they
should also think of him qua intelligence as a thing in itself, they still
persist in considering him in this respect also as an appearance. In this
view it would no doubt be a contradiction to suppose the causality of the
same subject (that is, his will) to be withdrawn from all the natural laws
of the sensible world. But this contradiction disappears, if they would
only bethink themselves and admit, as is reasonable, that behind the
appearances there must also lie at their root (although hidden) the things
in themselves, and that we cannot expect the laws of these to be the same
as those that govern their appearances.</p>
<p>The subjective impossibility of explaining the freedom of the will is
identical with the impossibility of discovering and explaining an interest
* which man can take in the moral law. Nevertheless he does actually take
an interest in it, the basis of which in us we call the moral feeling,
which some have falsely assigned as the standard of our moral judgement,
whereas it must rather be viewed as the subjective effect that the law
exercises on the will, the objective principle of which is furnished by
reason alone.</p>
<p>* Interest is that by which reason becomes practical, i.e.,<br/>
a cause determining the will. Hence we say of rational<br/>
beings only that they take an interest in a thing;<br/>
irrational beings only feel sensual appetites. Reason takes<br/>
a direct interest in action then only when the universal<br/>
validity of its maxims is alone sufficient to determine the<br/>
will. Such an interest alone is pure. But if it can<br/>
determine the will only by means of another object of desire<br/>
or on the suggestion of a particular feeling of the subject,<br/>
then reason takes only an indirect interest in the action,<br/>
and, as reason by itself without experience cannot discover<br/>
either objects of the will or a special feeling actuating<br/>
it, this latter interest would only be empirical and not a<br/>
pure rational interest. The logical interest of reason<br/>
(namely, to extend its insight) is never direct, but<br/>
presupposes purposes for which reason is employed.<br/></p>
<p>In order indeed that a rational being who is also affected through the
senses should will what reason alone directs such beings that they ought
to will, it is no doubt requisite that reason should have a power to
infuse a feeling of pleasure or satisfaction in the fulfilment of duty,
that is to say, that it should have a causality by which it determines the
sensibility according to its own principles. But it is quite impossible to
discern, i.e., to make it intelligible a priori, how a mere thought, which
itself contains nothing sensible, can itself produce a sensation of
pleasure or pain; for this is a particular kind of causality of which as
of every other causality we can determine nothing whatever a priori; we
must only consult experience about it. But as this cannot supply us with
any relation of cause and effect except between two objects of experience,
whereas in this case, although indeed the effect produced lies within
experience, yet the cause is supposed to be pure reason acting through
mere ideas which offer no object to experience, it follows that for us men
it is quite impossible to explain how and why the universality of the
maxim as a law, that is, morality, interests. This only is certain, that
it is not because it interests us that it has validity for us (for that
would be heteronomy and dependence of practical reason on sensibility,
namely, on a feeling as its principle, in which case it could never give
moral laws), but that it interests us because it is valid for us as men,
inasmuch as it had its source in our will as intelligences, in other
words, in our proper self, and what belongs to mere appearance is
necessarily subordinated by reason to the nature of the thing in itself.</p>
<p>The question then, "How a categorical imperative is possible," can be
answered to this extent, that we can assign the only hypothesis on which
it is possible, namely, the idea of freedom; and we can also discern the
necessity of this hypothesis, and this is sufficient for the practical
exercise of reason, that is, for the conviction of the validity of this
imperative, and hence of the moral law; but how this hypothesis itself is
possible can never be discerned by any human reason. On the hypothesis,
however, that the will of an intelligence is free, its autonomy, as the
essential formal condition of its determination, is a necessary
consequence. Moreover, this freedom of will is not merely quite possible
as a hypothesis (not involving any contradiction to the principle of
physical necessity in the connexion of the phenomena of the sensible
world) as speculative philosophy can show: but further, a rational being
who is conscious of causality through reason, that is to say, of a will
(distinct from desires), must of necessity make it practically, that is,
in idea, the condition of all his voluntary actions. But to explain how
pure reason can be of itself practical without the aid of any spring of
action that could be derived from any other source, i.e., how the mere
principle of the universal validity of all its maxims as laws (which would
certainly be the form of a pure practical reason) can of itself supply a
spring, without any matter (object) of the will in which one could
antecedently take any interest; and how it can produce an interest which
would be called purely moral; or in other words, how pure reason can be
practical- to explain this is beyond the power of human reason, and all
the labour and pains of seeking an explanation of it are lost.</p>
<p>It is just the same as if I sought to find out how freedom itself is
possible as the causality of a will. For then I quit the ground of
philosophical explanation, and I have no other to go upon. I might indeed
revel in the world of intelligences which still remains to me, but
although I have an idea of it which is well founded, yet I have not the
least knowledge of it, nor an I ever attain to such knowledge with all the
efforts of my natural faculty of reason. It signifies only a something
that remains over when I have eliminated everything belonging to the world
of sense from the actuating principles of my will, serving merely to keep
in bounds the principle of motives taken from the field of sensibility;
fixing its limits and showing that it does not contain all in all within
itself, but that there is more beyond it; but this something more I know
no further. Of pure reason which frames this ideal, there remains after
the abstraction of all matter, i.e., knowledge of objects, nothing but the
form, namely, the practical law of the universality of the maxims, and in
conformity with this conception of reason in reference to a pure world of
understanding as a possible efficient cause, that is a cause determining
the will. There must here be a total absence of springs; unless this idea
of an intelligible world is itself the spring, or that in which reason
primarily takes an interest; but to make this intelligible is precisely
the problem that we cannot solve.</p>
<p>Here now is the extreme limit of all moral inquiry, and it is of great
importance to determine it even on this account, in order that reason may
not on the one hand, to the prejudice of morals, seek about in the world
of sense for the supreme motive and an interest comprehensible but
empirical; and on the other hand, that it may not impotently flap its
wings without being able to move in the (for it) empty space of
transcendent concepts which we call the intelligible world, and so lose
itself amidst chimeras. For the rest, the idea of a pure world of
understanding as a system of all intelligences, and to which we ourselves
as rational beings belong (although we are likewise on the other side
members of the sensible world), this remains always a useful and
legitimate idea for the purposes of rational belief, although all
knowledge stops at its threshold, useful, namely, to produce in us a
lively interest in the moral law by means of the noble ideal of a
universal kingdom of ends in themselves (rational beings), to which we can
belong as members then only when we carefully conduct ourselves according
to the maxims of freedom as if they were laws of nature.</p>

<h2> CONCLUDING REMARK </h2>
<p>The speculative employment of reason with respect to nature leads to the
absolute necessity of some supreme cause of the world: the practical
employment of reason with a view to freedom leads also to absolute
necessity, but only of the laws of the actions of a rational being as
such. Now it is an essential principle of reason, however employed, to
push its knowledge to a consciousness of its necessity (without which it
would not be rational knowledge). It is, however, an equally essential
restriction of the same reason that it can neither discern the necessity
of what is or what happens, nor of what ought to happen, unless a
condition is supposed on which it is or happens or ought to happen. In
this way, however, by the constant inquiry for the condition, the
satisfaction of reason is only further and further postponed. Hence it
unceasingly seeks the unconditionally necessary and finds itself forced to
assume it, although without any means of making it comprehensible to
itself, happy enough if only it can discover a conception which agrees
with this assumption. It is therefore no fault in our deduction of the
supreme principle of morality, but an objection that should be made to
human reason in general, that it cannot enable us to conceive the absolute
necessity of an unconditional practical law (such as the categorical
imperative must be). It cannot be blamed for refusing to explain this
necessity by a condition, that is to say, by means of some interest
assumed as a basis, since the law would then cease to be a supreme law of
reason. And thus while we do not comprehend the practical unconditional
necessity of the moral imperative, we yet comprehend its
incomprehensibility, and this is all that can be fairly demanded of a
philosophy which strives to carry its principles up to the very limit of
human reason.</p>
