Judgement
depending on laws of pure practical reason seems, therefore, to be
subject to special difficulties arising from this, that a law of
freedom is to be applied to actions, which are events taking place
in the world of sense, and which, so far, belong to physical nature.

But here again is opened a favourable prospect for the pure
practical judgement. When I subsume under a pure practical law an
action possible to me in the world of sense, I am not concerned with
the possibility of the action as an event in the world of sense.
This is a matter that belongs to the decision of reason in its
theoretic use according to the law of causality, which is a pure
concept of the understanding, for which reason has a schema in the
sensible intuition. Physical causality, or the condition under which
it takes place, belongs to the physical concepts, the schema of
which is sketched by transcendental imagination. Here, however, we
have to do, not with the schema of a case that occurs according to
laws, but with the schema of a law itself (if the word is allowable
here), since the fact that the will (not the action relatively to
its effect) is determined by the law alone without any other
principle, connects the notion of causality with quite different
conditions from those which constitute physical connection.

The physical law being a law to which the objects of sensible
intuition, as such, are subject, must have a schema corresponding to
it- that is, a general procedure of the imagination (by which it
exhibits a priori to the senses the pure concept of the
understanding which the law determines). But the law of freedom
(that is, of a causality not subject to sensible conditions), and
consequently the concept of the unconditionally good, cannot have
any intuition, nor consequently any schema supplied to it for the
purpose of its application in concreto. Consequently the moral law has
no faculty but the understanding to aid its application to physical
objects (not the imagination); and the understanding for the
purposes of the judgement can provide for an idea of the reason, not a
schema of the sensibility, but a law, though only as to its form as
law; such a law, however, as can be exhibited in concreto in objects
of the senses, and therefore a law of nature. We can therefore call
this law the type of the moral law.

The rule of the judgement according to laws of pure practical reason
is this: ask yourself whether, if the action you propose were to
take place by a law of the system of nature of which you were yourself
a part, you could regard it as possible by your own will. Everyone
does, in fact, decide by this rule whether actions are morally good or
evil. Thus, people say: "If everyone permitted himself to deceive,
when he thought it to his advantage; or thought himself justified in
shortening his life as soon as he was thoroughly weary of it; or
looked with perfect indifference on the necessity of others; and if
you belonged to such an order of things, would you do so with the
assent of your own will? " Now everyone knows well that if he
secretly allows himself to deceive, it does not follow that everyone
else does so; or if, unobserved, he is destitute of compassion, others
would not necessarily be so to him; hence, this comparison of the
maxim of his actions with a universal law of nature is not the
determining principle of his will. Such a law is, nevertheless, a type
of the estimation of the maxim on moral principles. If the maxim of
the action is not such as to stand the test of the form of a universal
law of nature, then it is morally impossible. This is the judgement
even of common sense; for its ordinary judgements, even those of
experience, are always based on the law of nature. It has it therefore
always at hand, only that in cases where causality from freedom is
to be criticised, it makes that law of nature only the type of a law
of freedom, because, without something which it could use as an
example in a case of experience, it could not give the law of a pure
practical reason its proper use in practice.

It is therefore allowable to use the system of the world of sense as
the type of a supersensible system of things, provided I do not
transfer to the latter the intuitions, and what depends on them, but
merely apply to it the form of law in general (the notion of which
occurs even in the commonest use of reason, but cannot be definitely
known a priori for any other purpose than the pure practical use of
reason); for laws, as such, are so far identical, no matter from
what they derive their determining principles.

{BOOK_1|CHAPTER_2 ^paragraph 50}

Further, since of all the supersensible absolutely nothing [is
known] except freedom (through the moral law), and this only so far as
it is inseparably implied in that law, and moreover all
supersensible objects to which reason might lead us, following the
guidance of that law, have still no reality for us, except for the
purpose of that law, and for the use of mere practical reason; and
as reason is authorized and even compelled to use physical nature
(in its pure form as an object of the understanding) as the type of
the judgement; hence, the present remark will serve to guard against
reckoning amongst concepts themselves that which belongs only to the
typic of concepts. This, namely, as a typic of the judgement, guards
against the empiricism of practical reason, which founds the practical
notions of good and evil merely on experienced consequences (so-called
happiness). No doubt happiness and the infinite advantages which would
result from a will determined by self-love, if this will at the same
time erected itself into a universal law of nature, may certainly
serve as a perfectly suitable type of the morally good, but it is
not identical with it. The same typic guards also against the
mysticism of practical reason, which turns what served only as a
symbol into a schema, that is, proposes to provide for the moral
concepts actual intuitions, which, however, are not sensible
(intuitions of an invisible Kingdom of God), and thus plunges into the
transcendent. What is befitting the use of the moral concepts is
only the rationalism of the judgement, which takes from the sensible
system of nature only what pure reason can also conceive of itself,
that is, conformity to law, and transfers into the supersensible
nothing but what can conversely be actually exhibited by actions in
the world of sense according to the formal rule of a law of nature.
However, the caution against empiricism of practical reason is much
more important; for mysticism is quite reconcilable with the purity
and sublimity of the moral law, and, besides, it is not very natural
or agreeable to common habits of thought to strain one's imagination
to supersensible intuitions; and hence the danger on this side is
not so general. Empiricism, on the contrary, cuts up at the roots
the morality of intentions (in which, and not in actions only,
consists the high worth that men can and ought to give to themselves),
and substitutes for duty something quite different, namely, an
empirical interest, with which the inclinations generally are secretly
leagued; and empiricism, moreover, being on this account allied with
all the inclinations which (no matter what fashion they put on)
degrade humanity when they are raised to the dignity of a supreme
practical principle; and as these, nevertheless, are so favourable
to everyone's feelings, it is for that reason much more dangerous than
mysticism, which can never constitute a lasting condition of any great
number of persons.

CHAPTER III. Of the Motives of Pure Practical Reason.



What is essential in the moral worth of actions is that the moral
law should directly determine the will. If the determination of the
will takes place in conformity indeed to the moral law, but only by
means of a feeling, no matter of what kind, which has to be
presupposed in order that the law may be sufficient to determine the
will, and therefore not for the sake of the law, then the action
will possess legality, but not morality. Now, if we understand by
motive (elater animi) the subjective ground of determination of the
will of a being whose reason does not necessarily conform to the
objective law, by virtue of its own nature, then it will follow,
first, that no motives can be attributed to the Divine will, and that
the motives of the human will (as well as that of every created
rational being) can never be anything else than the moral law, and
consequently that the objective principle of determination must always
and alone be also the subjectively sufficient determining principle of
the action, if this is not merely to fulfil the letter of the law,
without containing its spirit. *



* We may say of every action that conforms to the law, but is not
done for the sake of the law, that it is morally good in the letter,
not in the spirit (the intention).



Since, then, for the purpose of giving the moral law influence
over the will, we must not seek for any other motives that might
enable us to dispense with the motive of the law itself, because
that would produce mere hypocrisy, without consistency; and it is even
dangerous to allow other motives (for instance, that of interest) even
to co-operate along with the moral law; hence nothing is left us but
to determine carefully in what way the moral law becomes a motive, and
what effect this has upon the faculty of desire. For as to the
question how a law can be directly and of itself a determining
principle of the will (which is the essence of morality), this is, for
human reason, an insoluble problem and identical with the question:
how a free will is possible. Therefore what we have to show a priori
is not why the moral law in itself supplies a motive, but what
effect it, as such, produces (or, more correctly speaking, must
produce) on the mind.

{BOOK_1|CHAPTER_3 ^paragraph 5}

The essential point in every determination of the will by the
moral law is that being a free will it is determined simply by the
moral law, not only without the co-operation of sensible impulses, but
even to the rejection of all such, and to the checking of all
inclinations so far as they might be opposed to that law. So far,
then, the effect of the moral law as a motive is only negative, and
this motive can be known a priori to be such. For all inclination
and every sensible impulse is founded on feeling, and the negative
effect produced on feeling (by the check on the inclinations) is
itself feeling; consequently, we can see a priori that the moral
law, as a determining principle of the will, must by thwarting all our
inclinations produce a feeling which may be called pain; and in this
we have the first, perhaps the only, instance in which we are able
from a priori considerations to determine the relation of a
cognition (in this case of pure practical reason) to the feeling of
pleasure or displeasure. All the inclinations together (which can be
reduced to a tolerable system, in which case their satisfaction is
called happiness) constitute self-regard (solipsismus). This is either
the self-love that consists in an excessive fondness for oneself
(philautia), or satisfaction with oneself (arrogantia). The former
is called particularly selfishness; the latter self-conceit. Pure
practical reason only checks selfishness, looking on it as natural and
active in us even prior to the moral law, so far as to limit it to the
condition of agreement with this law, and then it is called rational
self-love. But self-conceit reason strikes down altogether, since
all claims to self-esteem which precede agreement with the moral law
are vain and unjustifiable, for the certainty of a state of mind
that coincides with this law is the first condition of personal
worth (as we shall presently show more clearly), and prior to this
conformity any pretension to worth is false and unlawful. Now the
propensity to self-esteem is one of the inclinations which the moral
law checks, inasmuch as that esteem rests only on morality.
Therefore the moral law breaks down self-conceit. But as this law is
something positive in itself, namely, the form of an intellectual
causality, that is, of freedom, it must be an object of respect;
for, by opposing the subjective antagonism of the inclinations, it
weakens self-conceit; and since it even breaks down, that is,
humiliates, this conceit, it is an object of the highest respect
and, consequently, is the foundation of a positive feeling which is
not of empirical origin, but is known a priori. Therefore respect
for the moral law is a feeling which is produced by an intellectual
cause, and this feeling is the only one that we know quite a priori
and the necessity of which we can perceive.

In the preceding chapter we have seen that everything that
presents itself as an object of the will prior to the moral law is
by that law itself, which is the supreme condition of practical
reason, excluded from the determining principles of the will which
we have called the unconditionally good; and that the mere practical
form which consists in the adaptation of the maxims to universal
legislation first determines what is good in itself and absolutely,
and is the basis of the maxims of a pure will, which alone is good
in every respect. However, we find that our nature as sensible
beings is such that the matter of desire (objects of inclination,
whether of hope or fear) first presents itself to us; and our
pathologically affected self, although it is in its maxims quite unfit
for universal legislation; yet, just as if it constituted our entire
self, strives to put its pretensions forward first, and to have them
acknowledged as the first and original. This propensity to make
ourselves in the subjective determining principles of our choice serve
as the objective determining principle of the will generally may be
called self-love; and if this pretends to be legislative as an
unconditional practical principle it may be called self-conceit. Now
the moral law, which alone is truly objective (namely, in every
respect), entirely excludes the influence of self-love on the
supreme practical principle, and indefinitely checks the
self-conceit that prescribes the subjective conditions of the former
as laws. Now whatever checks our self-conceit in our own judgement
humiliates; therefore the moral law inevitably humbles every man
when he compares with it the physical propensities of his nature.
That, the idea of which as a determining principle of our will humbles
us in our self-consciousness, awakes respect for itself, so far as
it is itself positive and a determining principle. Therefore the moral
law is even subjectively a cause of respect. Now since everything that
enters into self-love belongs to inclination, and all inclination
rests on feelings, and consequently whatever checks all the feelings
together in self-love has necessarily, by this very circumstance, an
influence on feeling; hence we comprehend how it is possible to
perceive a priori that the moral law can produce an effect on feeling,
in that it excludes the inclinations and the propensity to make them
the supreme practical condition, i. e. , self-love, from all
participation in the supreme legislation. This effect is on one side
merely negative, but on the other side, relatively to the
restricting principle of pure practical reason, it is positive. No
special kind of feeling need be assumed for this under the name of a
practical or moral feeling as antecedent to the moral law and
serving as its foundation.

The negative effect on feeling (unpleasantness) is pathological,
like every influence on feeling and like every feeling generally.
But as an effect of the consciousness of the moral law, and
consequently in relation to a supersensible cause, namely, the subject
of pure practical reason which is the supreme lawgiver, this feeling
of a rational being affected by inclinations is called humiliation
(intellectual self-depreciation); but with reference to the positive
source of this humiliation, the law, it is respect for it. There is
indeed no feeling for this law; but inasmuch as it removes the
resistance out of the way, this removal of an obstacle is, in the
judgement of reason, esteemed equivalent to a positive help to its
causality. Therefore this feeling may also be called a feeling of
respect for the moral law, and for both reasons together a moral
feeling.

While the moral law, therefore, is a formal determining principle of
action by practical pure reason, and is moreover a material though
only objective determining principle of the objects of action as
called good and evil, it is also a subjective determining principle,
that is, a motive to this action, inasmuch as it has influence on
the morality of the subject and produces a feeling conducive to the
influence of the law on the will. There is here in the subject no
antecedent feeling tending to morality. For this is impossible,
since every feeling is sensible, and the motive of moral intention
must be free from all sensible conditions. On the contrary, while
the sensible feeling which is at the bottom of all our inclinations is
the condition of that impression which we call respect, the cause that
determines it lies in the pure practical reason; and this impression
therefore, on account of its origin, must be called, not a
pathological but a practical effect. For by the fact that the
conception of the moral law deprives self-love of its influence, and
self-conceit of its illusion, it lessens the obstacle to pure
practical reason and produces the conception of the superiority of its
objective law to the impulses of the sensibility; and thus, by
removing the counterpoise, it gives relatively greater weight to the
law in the judgement of reason (in the case of a will affected by
the aforesaid impulses). Thus the respect for the law is not a
motive to morality, but is morality itself subjectively considered
as a motive, inasmuch as pure practical reason, by rejecting all the
rival pretensions of self-love, gives authority to the law, which now
alone has influence. Now it is to be observed that as respect is an
effect on feeling, and therefore on the sensibility, of a rational
being, it presupposes this sensibility, and therefore also the
finiteness of such beings on whom the moral law imposes respect; and
that respect for the law cannot be attributed to a supreme being, or
to any being free from all sensibility, in whom, therefore, this
sensibility cannot be an obstacle to practical reason.

This feeling (which we call the moral feeling) is therefore produced
simply by reason. It does not serve for the estimation of actions
nor for the foundation of the objective moral law itself, but merely
as a motive to make this of itself a maxim. But what name could we
more suitably apply to this singular feeling which cannot be
compared to any pathological feeling? It is of such a peculiar kind
that it seems to be at the disposal of reason only, and that pure
practical reason.

{BOOK_1|CHAPTER_3 ^paragraph 10}

Respect applies always to persons only- not to things. The latter
may arouse inclination, and if they are animals (e. g. , horses, dogs,
etc. ), even love or fear, like the sea, a volcano, a beast of prey;
but never respect. Something that comes nearer to this feeling is
admiration, and this, as an affection, astonishment, can apply to
things also, e. g. , lofty mountains, the magnitude, number, and
distance of the heavenly bodies, the strength and swiftness of many
animals, etc. But all this is not respect. A man also may be an object
to me of love, fear, or admiration, even to astonishment, and yet
not be an object of respect. His jocose humour, his courage and
strength, his power from the rank he has amongst others, may inspire
me with sentiments of this kind, but still inner respect for him is
wanting. Fontenelle says, "I bow before a great man, but my mind
does not bow. " I would add, before an humble plain man, in whom I
perceive uprightness of character in a higher degree than I am
conscious of in myself,- my mind bows whether I choose it or not,
and though I bear my head never so high that he may not forget my
superior rank. Why is this? Because his example exhibits to me a law
that humbles my self-conceit when I compare it with my conduct: a law,
the practicability of obedience to which I see proved by fact before
my eyes. Now, I may even be conscious of a like degree of uprightness,
and yet the respect remains. For since in man all good is defective,
the law made visible by an example still humbles my pride, my standard
being furnished by a man whose imperfections, whatever they may be,
are not known to me as my own are, and who therefore appears to me
in a more favourable light. Respect is a tribute which we cannot
refuse to merit, whether we will or not; we may indeed outwardly
withhold it, but we cannot help feeling it inwardly.

Respect is so far from being a feeling of pleasure that we only
reluctantly give way to it as regards a man. We try to find
out something that may lighten the burden of it, some fault
to compensate us for the humiliation which such an example
causes. Even the dead are not always secure from this criticism,
especially if their example appears inimitable. Even the moral law
itself in its solemn majesty is exposed to this endeavour to save
oneself from yielding it respect. Can it be thought that it is for any
other reason that we are so ready to reduce it to the level of our
familiar inclination, or that it is for any other reason that we all
take such trouble to make it out to be the chosen precept of our own
interest well understood, but that we want to be free from the
deterrent respect which shows us our own unworthiness with such
severity? Nevertheless, on the other hand, so little is there pain
in it that if once one has laid aside self-conceit and allowed
practical influence to that respect, he can never be satisfied with
contemplating the majesty of this law, and the soul believes itself
elevated in proportion as it sees the holy law elevated above it and
its frail nature. No doubt great talents and activity proportioned
to them may also occasion respect or an analogous feeling. It is
very proper to yield it to them, and then it appears as if this
sentiment were the same thing as admiration. But if we look closer
we shall observe that it is always uncertain how much of the ability
is due to native talent, and how much to diligence in cultivating
it. Reason represents it to us as probably the fruit of cultivation,
and therefore as meritorious, and this notably reduces our
self-conceit, and either casts a reproach on us or urges us to
follow such an example in the way that is suitable to us. This
respect, then, which we show to such a person (properly speaking, to
the law that his example exhibits) is not mere admiration; and this is
confirmed also by the fact that when the common run of admirers
think they have learned from any source the badness of such a man's
character (for instance Voltaire's) they give up all respect for
him; whereas the true scholar still feels it at least with regard to
his talents, because he is himself engaged in a business and a
vocation which make imitation of such a man in some degree a law.

Respect for the moral law is, therefore, the only and the
undoubted moral motive, and this feeling is directed to no object,
except on the ground of this law. The moral law first determines the
will objectively and directly in the judgement of reason; and freedom,
whose causality can be determined only by the law, consists just in
this, that it restricts all inclinations, and consequently
self-esteem, by the condition of obedience to its pure law. This
restriction now has an effect on feeling, and produces the
impression of displeasure which can be known a priori from the moral
law. Since it is so far only a negative effect which, arising from the
influence of pure practical reason, checks the activity of the
subject, so far as it is determined by inclinations, and hence
checks the opinion of his personal worth (which, in the absence of
agreement with the moral law, is reduced to nothing); hence, the
effect of this law on feeling is merely humiliation. We can,
therefore, perceive this a priori, but cannot know by it the force
of the pure practical law as a motive, but only the resistance to
motives of the sensibility. But since the same law is objectively,
that is, in the conception of pure reason, an immediate principle of
determination of the will, and consequently this humiliation takes
place only relatively to the purity of the law; hence, the lowering of
the pretensions of moral self-esteem, that is, humiliation on the
sensible side, is an elevation of the moral, i. e. , practical, esteem
for the law itself on the intellectual side; in a word, it is
respect for the law, and therefore, as its cause is intellectual, a
positive feeling which can be known a priori. For whatever
diminishes the obstacles to an activity furthers this activity itself.
Now the recognition of the moral law is the consciousness of an
activity of practical reason from objective principles, which only
fails to reveal its effect in actions because subjective
(pathological) causes hinder it. Respect for the moral law then must
be regarded as a positive, though indirect, effect of it on feeling,
inasmuch as this respect weakens the impeding influence of
inclinations by humiliating self-esteem; and hence also as a subjective
principle of activity, that is, as a motive to obedience to the law,
and as a principle of the maxims of a life conformable to it. From the
notion of a motive arises that of an interest, which can never be
attributed to any being unless it possesses reason, and which
signifies a motive of the will in so far as it is conceived by the
reason. Since in a morally good will the law itself must be the
motive, the moral interest is a pure interest of practical reason
alone, independent of sense. On the notion of an interest is based
that of a maxim. This, therefore, is morally good only in case it
rests simply on the interest taken in obedience to the law. All
three notions, however, that of a motive, of an interest, and of a
maxim, can be applied only to finite beings. For they all suppose a
limitation of the nature of the being, in that the subjective
character of his choice does not of itself agree with the objective
law of a practical reason; they suppose that the being requires to
be impelled to action by something, because an internal obstacle
opposes itself. Therefore they cannot be applied to the Divine will.

There is something so singular in the unbounded esteem for the
pure moral law, apart from all advantage, as it is presented for our
obedience by practical reason, the voice of which makes even the
boldest sinner tremble and compels him to hide himself from it, that
we cannot wonder if we find this influence of a mere intellectual idea
on the feelings quite incomprehensible to speculative reason and
have to be satisfied with seeing so much of this a priori that such
a feeling is inseparably connected with the conception of the moral
law in every finite rational being. If this feeling of respect were
pathological, and therefore were a feeling of pleasure based on the
inner sense, it would be in vain to try to discover a connection of it
with any idea a priori. But [it] is a feeling that applies merely to
what is practical, and depends on the conception of a law, simply as
to its form, not on account of any object, and therefore cannot be
reckoned either as pleasure or pain, and yet produces an interest in
obedience to the law, which we call the moral interest, just as the
capacity of taking such an interest in the law (or respect for the
moral law itself) is properly the moral feeling.

The consciousness of a free submission of the will to the law, yet
combined with an inevitable constraint put upon all inclinations,
though only by our own reason, is respect for the law. The law that
demands this respect and inspires it is clearly no other than the
moral (for no other precludes all inclinations from exercising any
direct influence on the will). An action which is objectively
practical according to this law, to the exclusion of every determining
principle of inclination, is duty, and this by reason of that
exclusion includes in its concept practical obligation, that is, a
determination to actions, however reluctantly they may be done. The
feeling that arises from the consciousness of this obligation is not
pathological, as would be a feeling produced by an object of the
senses, but practical only, that is, it is made possible by a
preceding (objective) determination of the will and a causality of the
reason. As submission to the law, therefore, that is, as a command
(announcing constraint for the sensibly affected subject), it contains
in it no pleasure, but on the contrary, so far, pain in the action. On
the other hand, however, as this constraint is exercised merely by the
legislation of our own reason, it also contains something elevating,
and this subjective effect on feeling, inasmuch as pure practical
reason is the sole cause of it, may be called in this respect
self-approbation, since we recognize ourselves as determined thereto
solely by the law without any interest, and are now conscious of a
quite different interest subjectively produced thereby, and which is
purely practical and free; and our taking this interest in an action
of duty is not suggested by any inclination, but is commanded and
actually brought about by reason through the practical law; whence
this feeling obtains a special name, that of respect.

{BOOK_1|CHAPTER_3 ^paragraph 15}

The notion of duty, therefore, requires in the action,
objectively, agreement with the law, and, subjectively in its maxim,
that respect for the law shall be the sole mode in which the will is
determined thereby. And on this rests the distinction between the
consciousness of having acted according to duty and from duty, that
is, from respect for the law. The former (legality) is possible even
if inclinations have been the determining principles of the will;
but the latter (morality), moral worth, can be placed only in this,
that the action is done from duty, that is, simply for the sake of the
law. *



* If we examine accurately the notion of respect for persons as it
has been already laid down, we shall perceive that it always rests
on the consciousness of a duty which an example shows us, and that
respect, therefore, can never have any but a moral ground, and that it
is very good and even, in a psychological point of view, very useful
for the knowledge of mankind, that whenever we use this expression
we should attend to this secret and marvellous, yet often recurring,
regard which men in their judgement pay to the moral law.



It is of the greatest importance to attend with the utmost exactness
in all moral judgements to the subjective principle of all maxims,
that all the morality of actions may be placed in the necessity of
acting from duty and from respect for the law, not from love and
inclination for that which the actions are to produce. For men and all
created rational beings moral necessity is constraint, that is
obligation, and every action based on it is to be conceived as a duty,
not as a proceeding previously pleasing, or likely to be pleasing to
us of our own accord. As if indeed we could ever bring it about that
without respect for the law, which implies fear, or at least
apprehension of transgression, we of ourselves, like the independent
Deity, could ever come into possession of holiness of will by the
coincidence of our will with the pure moral law becoming as it were
part of our nature, never to be shaken (in which case the law would
cease to be a command for us, as we could never be tempted to be
untrue to it).

{BOOK_1|CHAPTER_3 ^paragraph 20}

The moral law is in fact for the will of a perfect being a law of
holiness, but for the will of every finite rational being a law of
duty, of moral constraint, and of the determination of its actions
by respect for this law and reverence for its duty. No other
subjective principle must be assumed as a motive, else while the
action might chance to be such as the law prescribes, yet, as does not
proceed from duty, the intention, which is the thing properly in
question in this legislation, is not moral.

It is a very beautiful thing to do good to men from love to them and
from sympathetic good will, or to be just from love of order; but this
is not yet the true moral maxim of our conduct which is suitable to
our position amongst rational beings as men, when we pretend with
fanciful pride to set ourselves above the thought of duty, like
volunteers, and, as if we were independent on the command, to want
to do of our own good pleasure what we think we need no command to do.
We stand under a discipline of reason and in all our maxims must not
forget our subjection to it, nor withdraw anything therefrom, or by an
egotistic presumption diminish aught of the authority of the law
(although our own reason gives it) so as to set the determining
principle of our will, even though the law be conformed to, anywhere
else but in the law itself and in respect for this law. Duty and
obligation are the only names that we must give to our relation to the
moral law. We are indeed legislative members of a moral kingdom
rendered possible by freedom, and presented to us by reason as an
object of respect; but yet we are subjects in it, not the sovereign,
and to mistake our inferior position as creatures, and
presumptuously to reject the authority of the moral law, is already to
revolt from it in spirit, even though the letter of it is fulfilled.

With this agrees very well the possibility of such a command as:
Love God above everything, and thy neighbour as thyself. * For as a
command it requires respect for a law which commands love and does not
leave it to our own arbitrary choice to make this our principle.
Love to God, however, considered as an inclination (pathological
love), is impossible, for He is not an object of the senses. The
same affection towards men is possible no doubt, but cannot be
commanded, for it is not in the power of any man to love anyone at
command; therefore it is only practical love that is meant in that
pith of all laws. To love God means, in this sense, to like to do
His commandments; to love one's neighbour means to like to practise
all duties towards him. But the command that makes this a rule
cannot command us to have this disposition in actions conformed to
duty, but only to endeavour after it. For a command to like to do a
thing is in itself contradictory, because if we already know of
ourselves what we are bound to do, and if further we are conscious
of liking to do it, a command would be quite needless; and if we do it
not willingly, but only out of respect for the law, a command that
makes this respect the motive of our maxim would directly counteract
the disposition commanded. That law of all laws, therefore, like all
the moral precepts of the Gospel, exhibits the moral disposition in
all its perfection, in which, viewed as an ideal of holiness, it is
not attainable by any creature, but yet is the pattern which we should
strive to approach, and in an uninterrupted but infinite progress
become like to. In fact, if a rational creature could ever reach
this point, that he thoroughly likes to do all moral laws, this
would mean that there does not exist in him even the possibility of
a desire that would tempt him to deviate from them; for to overcome
such a desire always costs the subject some sacrifice and therefore
requires self-compulsion, that is, inward constraint to something that
one does not quite like to do; and no creature can ever reach this
stage of moral disposition. For, being a creature, and therefore
always dependent with respect to what he requires for complete
satisfaction, he can never be quite free from desires and
inclinations, and as these rest on physical causes, they can never
of themselves coincide with the moral law, the sources of which are
quite different; and therefore they make it necessary to found the
mental disposition of one's maxims on moral obligation, not on ready
inclination, but on respect, which demands obedience to the law,
even though one may not like it; not on love, which apprehends no
inward reluctance of the will towards the law. Nevertheless, this
latter, namely, love to the law (which would then cease to be a
command, and then morality, which would have passed subjectively
into holiness, would cease to be virtue) must be the constant though
unattainable goal of his endeavours. For in the case of what we highly
esteem, but yet (on account of the consciousness of our weakness)
dread, the increased facility of satisfying it changes the most
reverential awe into inclination, and respect into love; at least this
would be the perfection of a disposition devoted to the law, if it
were possible for a creature to attain it.



* This law is in striking contrast with the principle of private
happiness which some make the supreme principle of morality. This
would be expressed thus: Love thyself above everything, and God and
thy neighbour for thine own sake.

{BOOK_1|CHAPTER_3 ^paragraph 25}



This reflection is intended not so much to clear up the
evangelical command just cited, in order to prevent religious
fanaticism in regard to love of God, but to define accurately the
moral disposition with regard directly to our duties towards men,
and to check, or if possible prevent, a merely moral fanaticism
which infects many persons. The stage of morality on which man (and,
as far as we can see, every rational creature) stands is respect for
the moral law. The disposition that he ought to have in obeying this
is to obey it from duty, not from spontaneous inclination, or from
an endeavour taken up from liking and unbidden; and this proper
moral condition in which he can always be is virtue, that is, moral
disposition militant, and not holiness in the fancied possession of
a perfect purity of the disposition of the will. It is nothing but
moral fanaticism and exaggerated self-conceit that is infused into the
mind by exhortation to actions as noble, sublime, and magnanimous,
by which men are led into the delusion that it is not duty, that is,
respect for the law, whose yoke (an easy yoke indeed, because reason
itself imposes it on us) they must bear, whether they like it or
not, that constitutes the determining principle of their actions,
and which always humbles them while they obey it; fancying that
those actions are expected from them, not from duty, but as pure
merit. For not only would they, in imitating such deeds from such a
principle, not have fulfilled the spirit of the law in the least,
which consists not in the legality of the action (without regard to
principle), but in the subjection of the mind to the law; not only
do they make the motives pathological (seated in sympathy or
self-love), not moral (in the law), but they produce in this way a
vain, high-flying, fantastic way of thinking, flattering themselves
with a spontaneous goodness of heart that needs neither spur nor
bridle, for which no command is needed, and thereby forgetting their
obligation, which they ought to think of rather than merit. Indeed
actions of others which are done with great sacrifice, and merely
for the sake of duty, may be praised as noble and sublime, but only so
far as there are traces which suggest that they were done wholly out
of respect for duty and not from excited feelings. If these,
however, are set before anyone as examples to be imitated, respect for
duty (which is the only true moral feeling) must be employed as the
motive- this severe holy precept which never allows our vain self-love
to dally with pathological impulses (however analogous they may be
to morality), and to take a pride in meritorious worth. Now if we
search we shall find for all actions that are worthy of praise a law
of duty which commands, and does not leave us to choose what may be
agreeable to our inclinations. This is the only way of representing
things that can give a moral training to the soul, because it alone is
capable of solid and accurately defined principles.

If fanaticism in its most general sense is a deliberate over
stepping of the limits of human reason, then moral fanaticism is
such an over stepping of the bounds that practical pure reason sets to
mankind, in that it forbids us to place the subjective determining
principle of correct actions, that is, their moral motive, in anything
but the law itself, or to place the disposition which is thereby
brought into the maxims in anything but respect for this law, and
hence commands us to take as the supreme vital principle of all
morality in men the thought of duty, which strikes down all
arrogance as well as vain self-love.

If this is so, it is not only writers of romance or sentimental
educators (although they may be zealous opponents of
sentimentalism), but sometimes even philosophers, nay, even the
severest of all, the Stoics, that have brought in moral fanaticism
instead of a sober but wise moral discipline, although the
fanaticism of the latter was more heroic, that of the former of an
insipid, effeminate character; and we may, without hypocrisy, say of
the moral teaching of the Gospel, that it first, by the purity of
its moral principle, and at the same time by its suitability to the
limitations of finite beings, brought all the good conduct of men
under the discipline of a duty plainly set before their eyes, which
does not permit them to indulge in dreams of imaginary moral
perfections; and that it also set the bounds of humility (that is,
self-knowledge) to self-conceit as well as to self-love, both which
are ready to mistake their limits.

Duty! Thou sublime and mighty name that dost embrace nothing
charming or insinuating, but requirest submission, and yet seekest not
to move the will by threatening aught that would arouse natural
aversion or terror, but merely holdest forth a law which of itself
finds entrance into the mind, and yet gains reluctant reverence
(though not always obedience), a law before which all inclinations are
dumb, even though they secretly counter-work it; what origin is
there worthy of thee, and where is to be found the root of thy noble
descent which proudly rejects all kindred with the inclinations; a
root to be derived from which is the indispensable condition of the
only worth which men can give themselves?

{BOOK_1|CHAPTER_3 ^paragraph 30}

It can be nothing less than a power which elevates man above himself
(as a part of the world of sense), a power which connects him with
an order of things that only the understanding can conceive, with a
world which at the same time commands the whole sensible world, and
with it the empirically determinable existence of man in time, as well
as the sum total of all ends (which totality alone suits such
unconditional practical laws as the moral). This power is nothing
but personality, that is, freedom and independence on the mechanism of
nature, yet, regarded also as a faculty of a being which is subject to
special laws, namely, pure practical laws given by its own reason;
so that the person as belonging to the sensible world is subject to
his own personality as belonging to the intelligible [supersensible]
world. It is then not to be wondered at that man, as belonging to both
worlds, must regard his own nature in reference to its second and
highest characteristic only with reverence, and its laws with the
highest respect.

On this origin are founded many expressions which designate the
worth of objects according to moral ideas. The moral law is holy
(inviolable). Man is indeed unholy enough, but he must regard humanity
in his own person as holy. In all creation every thing one chooses and
over which one has any power, may be used merely as means; man
alone, and with him every rational creature, is an end in himself.
By virtue of the autonomy of his freedom he is the subject of the
moral law, which is holy. Just for this reason every will, even
every person's own individual will, in relation to itself, is
restricted to the condition of agreement with the autonomy of the
rational being, that is to say, that it is not to be subject to any
purpose which cannot accord with a law which might arise from the will
of the passive subject himself; the latter is, therefore, never to
be employed merely as means, but as itself also, concurrently, an end.
We justly attribute this condition even to the Divine will, with
regard to the rational beings in the world, which are His creatures,
since it rests on their personality, by which alone they are ends in
themselves.

This respect-inspiring idea of personality which sets before our
eyes the sublimity of our nature (in its higher aspect), while at
the same time it shows us the want of accord of our conduct with it
and thereby strikes down self-conceit, is even natural to the
commonest reason and easily observed. Has not every even moderately
honourable man sometimes found that, where by an otherwise inoffensive
lie he might either have withdrawn himself from an unpleasant
business, or even have procured some advantages for a loved and
well-deserving friend, he has avoided it solely lest he should despise
himself secretly in his own eyes? When an upright man is in the
greatest distress, which he might have avoided if he could only have
disregarded duty, is he not sustained by the consciousness that he has
maintained humanity in its proper dignity in his own person and
honoured it, that he has no reason to be ashamed of himself in his own
sight, or to dread the inward glance of self-examination? This
consolation is not happiness, it is not even the smallest part of
it, for no one would wish to have occasion for it, or would,
perhaps, even desire a life in such circumstances. But he lives, and
he cannot endure that he should be in his own eyes unworthy of life.
This inward peace is therefore merely negative as regards what can
make life pleasant; it is, in fact, only the escaping the danger of
sinking in personal worth, after everything else that is valuable
has been lost. It is the effect of a respect for something quite
different from life, something in comparison and contrast with which
life with all its enjoyment has no value. He still lives only
because it is his duty, not because he finds anything pleasant in
life.

Such is the nature of the true motive of pure practical reason; it
is no other than the pure moral law itself, inasmuch as it makes us
conscious of the sublimity of our own supersensible existence and
subjectively produces respect for their higher nature in men who are
also conscious of their sensible existence and of the consequent
dependence of their pathologically very susceptible nature. Now with
this motive may be combined so many charms and satisfactions of life
that even on this account alone the most prudent choice of a
rational Epicurean reflecting on the greatest advantage of life
would declare itself on the side of moral conduct, and it may even
be advisable to join this prospect of a cheerful enjoyment of life
with that supreme motive which is already sufficient of itself; but
only as a counterpoise to the attractions which vice does not fail
to exhibit on the opposite side, and not so as, even in the smallest
degree, to place in this the proper moving power when duty is in
question. For that would be just the same as to wish to taint the
purity of the moral disposition in its source. The majesty of duty has
nothing to do with enjoyment of life; it has its special law and its
special tribunal, and though the two should be never so well shaken
together to be given well mixed, like medicine, to the sick soul,
yet they will soon separate of themselves; and if they do not, the
former will not act; and although physical life might gain somewhat in
force, the moral life would fade away irrecoverably.

Critical Examination of the Analytic of Pure Practical Reason.



By the critical examination of a science, or of a portion of it,
which constitutes a system by itself, I understand the inquiry and
proof why it must have this and no other systematic form, when we
compare it with another system which is based on a similar faculty
of knowledge. Now practical and speculative reason are based on the
same faculty, so far as both are pure reason. Therefore the difference
in their systematic form must be determined by the comparison of both,
and the ground of this must be assigned.

The Analytic of pure theoretic reason had to do with the knowledge
of such objects as may have been given to the understanding, and was
obliged therefore to begin from intuition and consequently (as this is
always sensible) from sensibility; and only after that could advance
to concepts (of the objects of this intuition), and could only end
with principles after both these had preceded. On the contrary,
since practical reason has not to do with objects so as to know
them, but with its own faculty of realizing them (in accordance with
the knowledge of them), that is, with a will which is a causality,
inasmuch as reason contains its determining principle; since,
consequently, it has not to furnish an object of intuition, but as
practical reason has to furnish only a law (because the notion of
causality always implies the reference to a law which determines the
existence of the many in relation to one another); hence a critical
examination of the Analytic of reason, if this is to be practical
reason (and this is properly the problem), must begin with the
possibility of practical principles a priori. Only after that can it
proceed to concepts of the objects of a practical reason, namely,
those of absolute good and evil, in order to assign them in accordance
with those principles (for prior to those principles they cannot
possibly be given as good and evil by any faculty of knowledge), and
only then could the section be concluded with the last chapter,
that, namely, which treats of the relation of the pure practical
reason to the sensibility and of its necessary influence thereon,
which is a priori cognisable, that is, of the moral sentiment. Thus
the Analytic of the practical pure reason has the whole extent of
the conditions of its use in common with the theoretical, but in
reverse order.
The Analytic of pure theoretic reason was divided
into transcendental Aesthetic and transcendental Logic, that of the
practical reversely into Logic and Aesthetic of pure practical
reason (if I may, for the sake of analogy merely, use these
designations, which are not quite suitable). This logic again was
there divided into the Analytic of concepts and that of principles:
here into that of principles and concepts. The Aesthetic also had in
the former case two parts, on account of the two kinds of sensible
intuition; here the sensibility is not considered as a capacity of
intuition at all, but merely as feeling (which can be a subjective
ground of desire), and in regard to it pure practical reason admits no
further division.

It is also easy to see the reason why this division into two parts
with its subdivision was not actually adopted here (as one might
have been induced to attempt by the example of the former critique).
For since it is pure reason that is here considered in its practical
use, and consequently as proceeding from a priori principles, and
not from empirical principles of determination, hence the division
of the analytic of pure practical reason must resemble that of a
syllogism; namely, proceeding from the universal in the major
premiss (the moral principle), through a minor premiss containing a
subsumption of possible actions (as good or evil) under the former, to
the conclusion, namely, the subjective determination of the will (an
interest in the possible practical good, and in the maxim founded on
it). He who has been able to convince himself of the truth of the
positions occurring in the Analytic will take pleasure in such
comparisons; for they justly suggest the expectation that we may
perhaps some day be able to discern the unity of the whole faculty
of reason (theoretical as well as practical) and be able to derive all
from one principle, which, is what human reason inevitably demands, as
it finds complete satisfaction only in a perfectly systematic unity of
its knowledge.

{BOOK_1|CHAPTER_3 ^paragraph 40}

If now we consider also the contents of the knowledge that we can
have of a pure practical reason, and by means of it, as shown by the
Analytic, we find, along with a remarkable analogy between it and
the theoretical, no less remarkable differences. As regards the
theoretical, the faculty of a pure rational cognition a priori could
be easily and evidently proved by examples from sciences (in which, as
they put their principles to the test in so many ways by methodical
use, there is not so much reason as in common knowledge to fear a
secret mixture of empirical principles of cognition). But, that pure
reason without the admixture of any empirical principle is practical
of itself, this could only be shown from the commonest practical use
of reason, by verifying the fact, that every man's natural reason
acknowledges the supreme practical principle as the supreme law of his
will- a law completely a priori and not depending on any sensible
data. It was necessary first to establish and verify the purity of its
origin, even in the judgement of this common reason, before science
could take it in hand to make use of it, as a fact, that is, prior
to all disputation about its possibility, and all the consequences
that may be drawn from it. But this circumstance may be readily
explained from what has just been said; because practical pure
reason must necessarily begin with principles, which therefore must be
the first data, the foundation of all science, and cannot be derived
from it. It was possible to effect this verification of moral
principles as principles of a pure reason quite well, and with
sufficient certainty, by a single appeal to the judgement of common
sense, for this reason, that anything empirical which might slip
into our maxims as a determining principle of the will can be detected
at once by the feeling of pleasure or pain which necessarily
attaches to it as exciting desire; whereas pure practical reason
positively refuses to admit this feeling into its principle as a
condition. The heterogeneity of the determining principles (the
empirical and rational) is clearly detected by this resistance of a
practically legislating reason against every admixture of inclination,
and by a peculiar kind of sentiment, which, however, does not
precede the legislation of the practical reason, but, on the contrary,
is produced by this as a constraint, namely, by the feeling of a
respect such as no man has for inclinations of whatever kind but for
the law only; and it is detected in so marked and prominent a manner
that even the most uninstructed cannot fail to see at once in an
example presented to him, that empirical principles of volition may
indeed urge him to follow their attractions, but that he can never
be expected to obey anything but the pure practical law of reason
alone.

The distinction between the doctrine of happiness and the doctrine
of morality, in the former of which empirical principles constitute
the entire foundation, while in the second they do not form the
smallest part of it, is the first and most important office of the
Analytic of pure practical reason; and it must proceed in it with as
much exactness and, so to speak, scrupulousness, as any geometer in
his work. The philosopher, however, has greater difficulties to
contend with here (as always in rational cognition by means of
concepts merely without construction), because he cannot take any
intuition as a foundation (for a pure noumenon). He has, however, this
advantage that, like the chemist, he can at any time make an
experiment with every man's practical reason for the purpose of
distinguishing the moral (pure) principle of determination from the
empirical; namely, by adding the moral law (as a determining
principle) to the empirically affected will (e. g. , that of the man who
would be ready to lie because he can gain something thereby). It is as
if the analyst added alkali to a solution of lime in hydrochloric
acid, the acid at once forsakes the lime, combines with the alkali,
and the lime is precipitated. Just in the same way, if to a man who is
otherwise honest (or who for this occasion places himself only in
thought in the position of an honest man), we present the moral law by
which he recognises the worthlessness of the liar, his practical
reason (in forming a judgement of what ought to be done) at once
forsakes the advantage, combines with that which maintains in him
respect for his own person (truthfulness), and the advantage after
it has been separated and washed from every particle of reason
(which is altogether on the side of duty) is easily weighed by
everyone, so that it can enter into combination with reason in other
cases, only not where it could be opposed to the moral law, which
reason never forsakes, but most closely unites itself with.

But it does not follow that this distinction between the principle
of happiness and that of morality is an opposition between them, and
pure practical reason does not require that we should renounce all
claim to happiness, but only that the moment duty is in question we
should take no account of happiness. It may even in certain respects
be a duty to provide for happiness; partly, because (including
skill, wealth, riches) it contains means for the fulfilment of our
duty; partly, because the absence of it (e. g. , poverty) implies
temptations to transgress our duty. But it can never be an immediate
duty to promote our happiness, still less can it be the principle of
all duty. Now, as all determining principles of the will, except the
law of pure practical reason alone (the moral law), are all
empirical and, therefore, as such, belong to the principle of
happiness, they must all be kept apart from the supreme principle of
morality and never be incorporated with it as a condition; since
this would be to destroy all moral worth just as much as any empirical
admixture with geometrical principles would destroy the certainty of
mathematical evidence, which in Plato's opinion is the most
excellent thing in mathematics, even surpassing their utility.

Instead, however, of the deduction of the supreme principle of
pure practical reason, that is, the explanation of the possibility
of such a knowledge a priori, the utmost we were able to do was to
show that if we saw the possibility of the freedom of an efficient
cause, we should also see not merely the possibility, but even the
necessity, of the moral law as the supreme practical law of rational
beings, to whom we attribute freedom of causality of their will;
because both concepts are so inseparably united that we might define
practical freedom as independence of the will on anything but the
moral law. But we cannot perceive the possibility of the freedom of an
efficient cause, especially in the world of sense; we are fortunate if
only we can be sufficiently assured that there is no proof of its
impossibility, and are now, by the moral law which postulates it,
compelled and therefore authorized to assume it. However, there are
still many who think that they can explain this freedom on empirical
principles, like any other physical faculty, and treat it as a
psychological property, the explanation of which only requires a
more exact study of the nature of the soul and of the motives of the
will, and not as a transcendental predicate of the causality of a
being that belongs to the world of sense (which is really the
point). They thus deprive us of the grand revelation which we obtain
through practical reason by means of the moral law, the revelation,
namely, of a supersensible world by the realization of the otherwise
transcendent concept of freedom, and by this deprive us also of the
moral law itself, which admits no empirical principle of
determination. Therefore it will be necessary to add something here as
a protection against this delusion and to exhibit empiricism in its
naked superficiality.

The notion of causality as physical necessity, in opposition to
the same notion as freedom, concerns only the existence of things so
far as it is determinable in time, and, consequently, as phenomena, in
opposition to their causality as things in themselves. Now if we
take the attributes of existence of things in time for attributes of
things in themselves (which is the common view), then it is impossible
to reconcile the necessity of the causal relation with freedom; they
are contradictory. For from the former it follows that every event,
and consequently every action that takes place at a certain point of
time, is a necessary result of what existed in time preceding. Now
as time past is no longer in my power, hence every action that I
perform must be the necessary result of certain determining grounds
which are not in my power, that is, at the moment in which I am acting
I am never free. Nay, even if I assume that my whole existence is
independent on any foreign cause (for instance, God), so that the
determining principles of my causality, and even of my whole
existence, were not outside myself, yet this would not in the least
transform that physical necessity into freedom. For at every moment of
time I am still under the necessity of being determined to action by
that which is not in my power, and the series of events infinite a
parte priori, which I only continue according to a pre-determined
order and could never begin of myself, would be a continuous
physical chain, and therefore my causality would never be freedom.

{BOOK_1|CHAPTER_3 ^paragraph 45}

If, then, we would attribute freedom to a being whose existence is
determined in time, we cannot except him from the law of necessity
as to all events in his existence and, consequently, as to his actions
also; for that would be to hand him over to blind chance. Now as
this law inevitably applies to all the causality of things, so far
as their existence is determinable in time, it follows that if this
were the mode in which we had also to conceive the existence of
these things in themselves, freedom must be rejected as a vain and
impossible conception. Consequently, if we would still save it, no
other way remains but to consider that the existence of a thing, so
far as it is determinable in time, and therefore its causality,
according to the law of physical necessity, belong to appearance,
and to attribute freedom to the same being as a thing in itself.
This is certainly inevitable, if we would retain both these
contradictory concepts together; but in application, when we try to
explain their combination in one and the same action, great
difficulties present themselves which seem to render such a
combination impracticable.

When I say of a man who commits a theft that, by the law of
causality, this deed is a necessary result of the determining causes
in preceding time, then it was impossible that it could not have
happened; how then can the judgement, according to the moral law, make
any change, and suppose that it could have been omitted, because the
law says that it ought to have been omitted; that is, how can a man be
called quite free at the same moment, and with respect to the same
action in which he is subject to an inevitable physical necessity?
Some try to evade this by saying that the causes that determine his
causality are of such a kind as to agree with a comparative notion
of freedom. According to this, that is sometimes called a free effect,
the determining physical cause of which lies within the acting thing
itself, e. g. , that which a projectile performs when it is in free
motion, in which case we use the word freedom, because while it is
in flight it is not urged by anything external; or as we call the
motion of a clock a free motion, because it moves its hands itself,
which therefore do not require to be pushed by external force; so
although the actions of man are necessarily determined by causes which
precede in time, we yet call them free, because these causes are ideas
produced by our own faculties, whereby desires are evoked on
occasion of circumstances, and hence actions are wrought according
to our own pleasure. This is a wretched subterfuge with which some
persons still let themselves be put off, and so think they have
solved, with a petty word- jugglery, that difficult problem, at the
solution of which centuries have laboured in vain, and which can
therefore scarcely be found so completely on the surface. In fact,
in the question about the freedom which must be the foundation of
all moral laws and the consequent responsibility, it does not matter
whether the principles which necessarily determine causality by a
physical law reside within the subject or without him, or in the
former case whether these principles are instinctive or are
conceived by reason, if, as is admitted by these men themselves, these
determining ideas have the ground of their existence in time and in
the antecedent state, and this again in an antecedent, etc. Then it
matters not that these are internal; it matters not that they have a
psychological and not a mechanical causality, that is, produce actions
by means of ideas and not by bodily movements; they are still
determining principles of the causality of a being whose existence
is determinable in time, and therefore under the necessitation of
conditions of past time, which therefore, when the subject has to act,
are no longer in his power. This may imply psychological freedom (if
we choose to apply this term to a merely internal chain of ideas in
the mind), but it involves physical necessity and, therefore, leaves
no room for transcendental freedom, which must be conceived as
independence on everything empirical, and, consequently, on nature
generally, whether it is an object of the internal sense considered in
time only, or of the external in time and space. Without this
freedom (in the latter and true sense), which alone is practical a
priori, no moral law and no moral imputation are possible. Just for
this reason the necessity of events in time, according to the physical
law of causality, may be called the mechanism of nature, although we
do not mean by this that things which are subject to it must be really
material machines. We look here only to the necessity of the
connection of events in a time-series as it is developed according
to the physical law, whether the subject in which this development
takes place is called automaton materiale when the mechanical being is
moved by matter, or with Leibnitz spirituale when it is impelled by
ideas; and if the freedom of our will were no other than the latter
(say the psychological and comparative, not also transcendental,
that is, absolute), then it would at bottom be nothing better than the
freedom of a turnspit, which, when once it is wound up, accomplishes
its motions of itself.

Now, in order to remove in the supposed case the apparent
contradiction between freedom and the mechanism of nature in one and
the same action, we must remember what was said in the Critique of
Pure Reason, or what follows therefrom; viz. , that the necessity of
nature, which cannot co-exist with the freedom of the subject,
appertains only to the attributes of the thing that is subject to
time-conditions, consequently only to those of the acting subject as a
phenomenon; that therefore in this respect the determining
principles of every action of the same reside in what belongs to
past time and is no longer in his power (in which must be included his
own past actions and the character that these may determine for him in
his own eyes as a phenomenon). But the very same subject, being on the
other side conscious of himself as a thing in himself, considers his
existence also in so far as it is not subject to time-conditions,
and regards himself as only determinable by laws which he gives
himself through reason; and in this his existence nothing is
antecedent to the determination of his will, but every action, and
in general every modification of his existence, varying according to
his internal sense, even the whole series of his existence as a
sensible being is in the consciousness of his supersensible
existence nothing but the result, and never to be regarded as the
determining principle, of his causality as a noumenon. In this view
now the rational being can justly say of every unlawful action that he
performs, that he could very well have left it undone; although as
appearance it is sufficiently determined in the past, and in this
respect is absolutely necessary; for it, with all the past which
determines it, belongs to the one single phenomenon of his character
which he makes for himself, in consequence of which he imputes the
causality of those appearances to himself as a cause independent on
sensibility.

With this agree perfectly the judicial sentences of that wonderful
faculty in us which we call conscience. A man may use as much art as
he likes in order to paint to himself an unlawful act, that he
remembers, as an unintentional error, a mere oversight, such as one
can never altogether avoid, and therefore as something in which he was
carried away by the stream of physical necessity, and thus to make
himself out innocent, yet he finds that the advocate who speaks in his
favour can by no means silence the accuser within, if only he is
conscious that at the time when he did this wrong he was in his
senses, that is, in possession of his freedom; and, nevertheless, he
accounts for his error from some bad habits, which by gradual
neglect of attention he has allowed to grow upon him to such a
degree that he can regard his error as its natural consequence,
although this cannot protect him from the blame and reproach which
he casts upon himself. This is also the ground of repentance for a
long past action at every recollection of it; a painful feeling
produced by the moral sentiment, and which is practically void in so
far as it cannot serve to undo what has been done. (Hence Priestley,
as a true and consistent fatalist, declares it absurd, and he deserves
to be commended for this candour more than those who, while they
maintain the mechanism of the will in fact, and its freedom in words
only, yet wish it to be thought that they include it in their system
of compromise, although they do not explain the possibility of such
moral imputation. ) But the pain is quite legitimate, because when
the law of our intelligible [supersensible] existence (the moral
law) is in question, reason recognizes no distinction of time, and
only asks whether the event belongs to me, as my act, and then
always morally connects the same feeling with it, whether it has
happened just now or long ago. For in reference to the supersensible
consciousness of its existence (i. e. , freedom) the life of sense is
but a single phenomenon, which, inasmuch as it contains merely
manifestations of the mental disposition with regard to the moral
law (i. e. , of the character), must be judged not according to the
physical necessity that belongs to it as phenomenon, but according
to the absolute spontaneity of freedom. It may therefore be admitted
that, if it were possible to have so profound an insight into a
man's mental character as shown by internal as well as external
actions as to know all its motives, even the smallest, and likewise
all the external occasions that can influence them, we could calculate
a man's conduct for the future with as great certainty as a lunar or
solar eclipse; and nevertheless we may maintain that the man is
free. In fact, if we were capable of a further glance, namely, an
intellectual intuition of the same subject (which indeed is not
granted to us, and instead of it we have only the rational concept),
then we should perceive that this whole chain of appearances in regard
to all that concerns the moral laws depends on the spontaneity of
the subject as a thing in itself, of the determination of which no
physical explanation can be given. In default of this intuition, the
moral law assures us of this distinction between the relation of our
actions as appearance to our sensible nature, and the relation of this
sensible nature to the supersensible substratum in us. In this view,
which is natural to our reason, though inexplicable, we can also
justify some judgements which we passed with all conscientiousness,
and which yet at first sight seem quite opposed to all equity. There
are cases in which men, even with the same education which has been
profitable to others, yet show such early depravity, and so continue
to progress in it to years of manhood, that they are thought to be
born villains, and their character altogether incapable of
improvement; and nevertheless they are judged for what they do or
leave undone, they are reproached for their faults as guilty; nay,
they themselves (the children) regard these reproaches as well
founded, exactly as if in spite of the hopeless natural quality of
mind ascribed to them, they remained just as responsible as any
other man. This could not happen if we did not suppose that whatever
springs from a man's choice (as every action intentionally performed
undoubtedly does) has as its foundation a free causality, which from
early youth expresses its character in its manifestations (i. e. ,
actions). These, on account of the uniformity of conduct, exhibit a
natural connection, which however does not make the vicious quality of
the will necessary, but on the contrary, is the consequence of the
evil principles voluntarily adopted and unchangeable, which only
make it so much the more culpable and deserving of punishment. There
still remains a difficulty in the combination of freedom with the
mechanism of nature in a being belonging to the world of sense; a
difficulty which, even after all the foregoing is admitted,
threatens freedom with complete destruction. But with this danger
there is also a circumstance that offers hope of an issue still
favourable to freedom; namely, that the same difficulty presses much
more strongly (in fact as we shall presently see, presses only) on the
system that holds the existence determinable in time and space to be
the existence of things in themselves; it does not therefore oblige us
to give up our capital supposition of the ideality of time as a mere
form of sensible intuition, and consequently as a mere manner of
representation which is proper to the subject as belonging to the
world of sense; and therefore it only requires that this view be
reconciled with this idea.

The difficulty is as follows: Even if it is admitted that the
supersensible subject can be free with respect to a given action,
although, as a subject also belonging to the world of sense, he is
under mechanical conditions with respect to the same action, still, as
soon as we allow that God as universal first cause is also the cause
of the existence of substance (a proposition which can never be
given up without at the same time giving up the notion of God as the
Being of all beings, and therewith giving up his all sufficiency, on
which everything in theology depends), it seems as if we must admit
that a man's actions have their determining principle in something
which is wholly out of his power- namely, in the causality of a
Supreme Being distinct from himself and on whom his own existence
and the whole determination of his causality are absolutely dependent.
In point of fact, if a man's actions as belonging to his modifications
in time were not merely modifications of him as appearance, but as a
thing in itself, freedom could not be saved. Man would be a marionette
or an automaton, like Vaucanson's, prepared and wound up by the
Supreme Artist. Self-consciousness would indeed make him a thinking
automaton; but the consciousness of his own spontaneity would be
mere delusion if this were mistaken for freedom, and it would
deserve this name only in a comparative sense, since, although the
proximate determining causes of its motion and a long series of
their determining causes are internal, yet the last and highest is
found in a foreign hand. Therefore I do not see how those who still
insist on regarding time and space as attributes belonging to the
existence of things in themselves, can avoid admitting the fatality of
actions; or if (like the otherwise acute Mendelssohn) they allow
them to be conditions necessarily belonging to the existence of finite
and derived beings, but not to that of the infinite Supreme Being, I
do not see on what ground they can justify such a distinction, or,
indeed, how they can avoid the contradiction that meets them, when
they hold that existence in time is an attribute necessarily belonging
to finite things in themselves, whereas God is the cause of this
existence, but cannot be the cause of time (or space) itself (since
this must be presupposed as a necessary a priori condition of the
existence of things); and consequently as regards the existence of
these things. His causality must be subject to conditions and even
to the condition of time; and this would inevitably bring in
everything contradictory to the notions of His infinity and
independence. On the other hand, it is quite easy for us to draw the
distinction between the attribute of the divine existence of being
independent on all time-conditions, and that of a being of the world
of sense, the distinction being that between the existence of a
being in itself and that of a thing in appearance. Hence, if this
ideality of time and space is not adopted, nothing remains but
Spinozism, in which space and time are essential attributes of the
Supreme Being Himself, and the things dependent on Him (ourselves,
therefore, included) are not substances, but merely accidents inhering
in Him; since, if these things as His effects exist in time only, this
being the condition of their existence in themselves, then the actions
of these beings must be simply His actions which He performs in some
place and time. Thus, Spinozism, in spite of the absurdity of its
fundamental idea, argues more consistently than the creation theory
can, when beings assumed to be substances, and beings in themselves
existing in time, are regarded as effects of a Supreme Cause, and
yet as not [belonging] to Him and His action, but as separate
substances.

{BOOK_1|CHAPTER_3 ^paragraph 50}

The above-mentioned difficulty is resolved briefly and clearly as
follows: If existence in time is a mere sensible mode of
representation belonging to thinking beings in the world and
consequently does not apply to them as things in themselves, then
the creation of these beings is a creation of things in themselves,
since the notion of creation does not belong to the sensible form of
representation of existence or to causality, but can only be
referred to noumena. Consequently, when I say of beings in the world
of sense that they are created, I so far regard them as noumena. As it
would be a contradiction, therefore, to say that God is a creator of
appearances, so also it is a contradiction to say that as creator He
is the cause of actions in the world of sense, and therefore as
appearances, although He is the cause of the existence of the acting
beings (which are noumena). If now it is possible to affirm freedom in
spite of the natural mechanism of actions as appearances (by regarding
existence in time as something that belongs only to appearances, not
to things in themselves), then the circumstance that the acting beings
are creatures cannot make the slightest difference, since creation
concerns their supersensible and not their sensible existence, and,
therefore, cannot be regarded as the determining principle of the
appearances. It would be quite different if the beings in the world as
things in themselves existed in time, since in that case the creator
of substance would be at the same time the author of the whole
mechanism of this substance.

Of so great importance is the separation of time (as well as
space) from the existence of things in themselves which was effected
in the Critique of the Pure Speculative Reason.

It may be said that the solution here proposed involves great
difficulty in itself and is scarcely susceptible of a lucid
exposition. But is any other solution that has been attempted, or that
may be attempted, easier and more intelligible? Rather might we say
that the dogmatic teachers of metaphysics have shown more shrewdness
than candour in keeping this difficult point out of sight as much as
possible, in the hope that if they said nothing about it, probably
no one would think of it. If science is to be advanced, all
difficulties must be laid open, and we must even search for those that
are hidden, for every difficulty calls forth a remedy, which cannot be
discovered without science gaining either in extent or in exactness;
and thus even obstacles become means of increasing the thoroughness of
science. On the other hand, if the difficulties are intentionally
concealed, or merely removed by palliatives, then sooner or later they
burst out into incurable mischiefs, which bring science to ruin in
an absolute scepticism.

Since it is, properly speaking, the notion of freedom alone amongst all
the ideas of pure speculative reason that so greatly enlarges our
knowledge in the sphere of the supersensible, though only of our
practical knowledge, I ask myself why it exclusively possesses so great
fertility, whereas the others only designate the vacant space for
possible beings of the pure understanding, but are unable by any means
to define the concept of them. I presently find that as I cannot think
anything without a category, I must first look for a category for the
rational idea of freedom with which I am now concerned; and this is the
category of causality; and although freedom, a concept of the reason,
being a transcendent concept, cannot have any intuition corresponding to
it, yet the concept of the understanding- for the synthesis of which the
former demands the unconditioned- (namely, the concept of causality)
must have a sensible intuition given, by which first its objective
reality is assured. Now, the categories are all divided into two
classes- the mathematical, which concern the unity of synthesis in the
conception of objects, and the dynamical, which refer to the unity of
synthesis in the conception of the existence of objects. The former
(those of magnitude and quality) always contain a synthesis of the
homogeneous, and it is not possible to find in this the unconditioned
antecedent to what is given in sensible intuition as conditioned in
space and time, as this would itself have to belong to space and time,
and therefore be again still conditioned. Whence it resulted in the
Dialectic of Pure Theoretic Reason that the opposite methods of
attaining the unconditioned and the totality of the conditions were both
wrong. The categories of the second class (those of causality and of the
necessity of a thing) did not require this homogeneity (of the
conditioned and the condition in synthesis), since here what we have to
explain is not how the intuition is compounded from a manifold in it,
but only how the existence of the conditioned object corresponding to it
is added to the existence of the condition (added, namely, in the
understanding as connected therewith); and in that case it was allowable
to suppose in the supersensible world the unconditioned antecedent to
the altogether conditioned in the world of sense (both as regards the
causal connection and the contingent existence of things themselves),
although this unconditioned remained indeterminate, and to make the
synthesis transcendent. Hence, it was found in the Dialectic of the Pure
Speculative Reason that the two apparently opposite methods of obtaining
for the conditioned the unconditioned were not really contradictory,
e. g. , in the synthesis of causality to conceive for the conditioned in
the series of causes and effects of the sensible world, a causality
which has no sensible condition, and that the same action which, as
belonging to the world of sense, is always sensibly conditioned, that
is, mechanically necessary, yet at the same time may be derived from a
causality not sensibly conditioned- being the causality of the acting
being as belonging to the supersensible world- and may consequently be
conceived as free. Now, the only point in question was to change this
may be into is; that is, that we should be able to show in an actual
case, as it were by a fact, that certain actions imply such a causality
(namely, the intellectual, sensibly unconditioned), whether they are
actual or only commanded, that is, objectively necessary in a practical
sense. We could not hope to find this connexion in actions actually
given in experience as events of the sensible world, since causality
with freedom must always be sought outside the world of sense in the
world of intelligence. But things of sense are the only things offered
to our perception and observation. Hence, nothing remained but to find
an incontestable objective principle of causality which excludes all
sensible conditions: that is, a principle in which reason does not
appeal further to something else as a determining ground of its
causality, but contains this determining ground itself by means of that
principle, and in which therefore it is itself as pure reason practical.
Now, this principle had not to be searched for or discovered; it had
long been in the reason of all men, and incorporated in their nature,
and is the principle of morality. Therefore, that unconditioned
causality, with the faculty of it, namely, freedom, is no longer merely
indefinitely and problematically thought (this speculative reason could
prove to be feasible), but is even as regards the law of its causality
definitely and assertorially known; and with it the fact that a being (I
myself), belonging to the world of sense, belongs also to the
supersensible world, this is also positively known, and thus the reality
of the supersensible world is established and in practical respects
definitely given, and this definiteness, which for theoretical purposes
would be transcendent, is for practical purposes immanent. We could not,
however, make a similar step as regards the second dynamical idea,
namely, that of a necessary being. We could not rise to it from the
sensible world without the aid of the first dynamical idea. For if we
attempted to do so, we should have ventured to leave at a bound all that
is given to us, and to leap to that of which nothing is given us that
can help us to effect the connection of such a supersensible being with
the world of sense (since the necessary being would have to be known as
given outside ourselves). On the other hand, it is now obvious that this
connection is quite possible in relation to our own subject, inasmuch as
I know myself to be on the one side as an intelligible [supersensible]
being determined by the moral law (by means of freedom), and on the
other side as acting in the world of sense. It is the concept of freedom
alone that enables us to find the unconditioned and intelligible for the
conditioned and sensible without going out of ourselves. For it is our
own reason that by means of the supreme and unconditional practical law
knows that itself and the being that is conscious of this law (our own
person) belong to the pure world of understanding, and moreover defines
the manner in which, as such, it can be active. In this way it can be
understood why in the whole faculty of reason it is the practical reason
only that can help us to pass beyond the world of sense and give us
knowledge of a supersensible order and connection, which, however, for
this very reason cannot be extended further than is necessary for pure
practical purposes.

Let me be permitted on this occasion to make one more remark,
namely, that every step that we make with pure reason, even in the
practical sphere where no attention is paid to subtle speculation,
nevertheless accords with all the material points of the Critique of
the Theoretical Reason as closely and directly as if each step had
been thought out with deliberate purpose to establish this
confirmation. Such a thorough agreement, wholly unsought for and quite
obvious (as anyone can convince himself, if he will only carry moral
inquiries up to their principles), between the most important
proposition of practical reason and the often seemingly too subtle and
needless remarks of the Critique of the Speculative Reason,
occasions surprise and astonishment, and confirms the maxim already
recognized and praised by others, namely, that in every scientific
inquiry we should pursue our way steadily with all possible
exactness and frankness, without caring for any objections that may be
raised from outside its sphere, but, as far as we can, to carry out
our inquiry truthfully and completely by itself. Frequent
observation has convinced me that, when such researches are concluded,
that which in one part of them appeared to me very questionable,
considered in relation to other extraneous doctrines, when I left this
doubtfulness out of sight for a time and only attended to the business
in hand until it was completed, at last was unexpectedly found to
agree perfectly with what had been discovered separately without the
least regard to those doctrines, and without any partiality or
prejudice for them. Authors would save themselves many errors and much
labour lost (because spent on a delusion) if they could only resolve
to go to work with more frankness.

BOOK II. Dialectic of Pure Practical Reason.



CHAPTER I. Of a Dialectic of Pure Practical Reason Generally.



Pure reason always has its dialetic, whether it is considered in its
speculative or its practical employment; for it requires the
absolute totality of the 'conditions of what is given conditioned, and
this can only be found in things in themselves. But as all conceptions
of things in themselves must be referred to intuitions, and with us
men these can never be other than sensible and hence can never
enable us to know objects as things in themselves but only as
appearances, and since the unconditioned can never be found in this
chain of appearances which consists only of conditioned and
conditions; thus from applying this rational idea of the totality of
the conditions (in other words of the unconditioned) to appearances,
there arises an inevitable illusion, as if these latter were things in
themselves (for in the absence of a warning critique they are always
regarded as such). This illusion would never be noticed as delusive if
it did not betray itself by a conflict of reason with itself, when
it applies to appearances its fundamental principle of presupposing
the unconditioned to everything conditioned. By this, however,
reason is compelled to trace this illusion to its source, and search
how it can be removed, and this can only be done by a complete
critical examination of the whole pure faculty of reason; so that
the antinomy of the pure reason which is manifest in its dialectic
is in fact the most beneficial error into which human reason could
ever have fallen, since it at last drives us to search for the key
to escape from this labyrinth; and when this key is found, it
further discovers that which we did not seek but yet had need of,
namely, a view into a higher and an immutable order of things, in
which we even now are, and in which we are thereby enabled by definite
precepts to continue to live according to the highest dictates of
reason.

It may be seen in detail in the Critique of Pure Reason how in its
speculative employment this natural dialectic is to be solved, and how
the error which arises from a very natural illusion may be guarded
against. But reason in its practical use is not a whit better off.
As pure practical reason, it likewise seeks to find the
unconditioned for the practically conditioned (which rests on
inclinations and natural wants), and this is not as the determining
principle of the will, but even when this is given (in the moral
law) it seeks the unconditioned totality of the object of pure
practical reason under the name of the summum bonum.

To define this idea practically, i. e. , sufficiently for the maxims
of our rational conduct, is the business of practical wisdom, and this
again as a science is philosophy, in the sense in which the word was
understood by the ancients, with whom it meant instruction in the
conception in which the summum bonum was to be placed, and the conduct
by which it was to be obtained. It would be well to leave this word in
its ancient signification as a doctrine of the summum bonum, so far as
reason endeavours to make this into a science. For on the one hand the
restriction annexed would suit the Greek expression (which signifies
the love of wisdom), and yet at the same time would be sufficient to
embrace under the name of philosophy the love of science: that is to
say, of all speculative rational knowledge, so far as it is
serviceable to reason, both for that conception and also for the
practical principle determining our conduct, without letting out of
sight the main end, on account of which alone it can be called a
doctrine of practical wisdom. On the other hand, it would be no harm
to deter the self-conceit of one who ventures to claim the title of
philosopher by holding before him in the very definition a standard of
self-estimation which would very much lower his pretensions. For a
teacher of wisdom would mean something more than a scholar who has not
come so far as to guide himself, much less to guide others, with
certain expectation of attaining so high an end: it would mean a
master in the knowledge of wisdom, which implies more than a modest
man would claim for himself. Thus philosophy as well as wisdom would
always remain an ideal, which objectively is presented complete in
reason alone, while subjectively for the person it is only the goal of
his unceasing endeavours; and no one would be justified in
professing to be in possession of it so as to assume the name of
philosopher who could not also show its infallible effects in his
own person as an example (in his self-mastery and the unquestioned
interest that he takes pre-eminently in the general good), and this
the ancients also required as a condition of deserving that honourable
title.

{BOOK_2|CHAPTER_1 ^paragraph 5}

We have another preliminary remark to make respecting the
dialectic of the pure practical reason, on the point of the definition
of the summum bonum (a successful solution of which dialectic would
lead us to expect, as in case of that of the theoretical reason, the
most beneficial effects, inasmuch as the self-contradictions of pure
practical reason honestly stated, and not concealed, force us to
undertake a complete critique of this faculty).

The moral law is the sole determining principle of a pure will.
But since this is merely formal (viz. , as prescribing only the form of
the maxim as universally legislative), it abstracts as a determining
principle from all matter that is to say, from every object of
volition. Hence, though the summum bonum may be the whole object of
a pure practical reason, i. e. , a pure will, yet it is not on that
account to be regarded as its determining principle; and the moral law
alone must be regarded as the principle on which that and its
realization or promotion are aimed at. This remark is important in
so delicate a case as the determination of moral principles, where the
slightest misinterpretation perverts men's minds. For it will have
been seen from the Analytic that, if we assume any object under the
name of a good as a determining principle of the will prior to the
moral law and then deduce from it the supreme practical principle,
this would always introduce heteronomy and crush out the moral
principle.

It is, however, evident that if the notion of the summum bonum
includes that of the moral law as its supreme condition, then the
summum bonum would not merely be an object, but the notion of it and
the conception of its existence as possible by our own practical
reason would likewise be the determining principle of the will,
since in that case the will is in fact determined by the moral law
which is already included in this conception, and by no other
object, as the principle of autonomy requires. This order of the
conceptions of determination of the will must not be lost sight of, as
otherwise we should misunderstand ourselves and think we had fallen
into a contradiction, while everything remains in perfect harmony.

BOOK_2|CHAPTER_2

CHAPTER II. Of the Dialectic of Pure Reason in defining the

Conception of the "Summum Bonum".



The conception of the summum itself contains an ambiguity which
might occasion needless disputes if we did not attend to it. The
summum may mean either the supreme (supremum) or the perfect
(consummatum). The former is that condition which is itself
unconditioned, i. e. , is not subordinate to any other (originarium);
the second is that whole which is not a part of a greater whole of the
same kind (perfectissimum). It has been shown in the Analytic that
virtue (as worthiness to be happy) is the supreme condition of all
that can appear to us desirable, and consequently of all our pursuit
of happiness, and is therefore the supreme good. But it does not
follow that it is the whole and perfect good as the object of the
desires of rational finite beings; for this requires happiness also,
and that not merely in the partial eyes of the person who makes
himself an end, but even in the judgement of an impartial reason,
which regards persons in general as ends in themselves. For to need
happiness, to deserve it, and yet at the same time not to
participate in it, cannot be consistent with the perfect volition of a
rational being possessed at the same time of all power, if, for the
sake of experiment, we conceive such a being. Now inasmuch as virtue
and happiness together constitute the possession of the summum bonum
in a person, and the distribution of happiness in exact proportion
to morality (which is the worth of the person, and his worthiness to
be happy) constitutes the summum bonum of a possible world; hence this
summum bonum expresses the whole, the perfect good, in which, however,
virtue as the condition is always the supreme good, since it has no
condition above it; whereas happiness, while it is pleasant to the
possessor of it, is not of itself absolutely and in all respects good,
but always presupposes morally right behaviour as its condition.

When two elements are necessarily united in one concept, they must
be connected as reason and consequence, and this either so that
their unity is considered as analytical (logical connection), or as
synthetical (real connection) the former following the law of
identity, the latter that of causality. The connection of virtue and
happiness may therefore be understood in two ways: either the
endeavour to be virtuous and the rational pursuit of happiness are not
two distinct actions, but absolutely identical, in which case no maxim
need be made the principle of the former, other than what serves for
the latter; or the connection consists in this, that virtue produces
happiness as something distinct from the consciousness of virtue, as a
cause produces an effect.

The ancient Greek schools were, properly speaking, only two, and
in determining the conception of the summum bonum these followed in
fact one and the same method, inasmuch as they did not allow virtue
and happiness to be regarded as two distinct elements of the summum
bonum, and consequently sought the unity of the principle by the
rule of identity; but they differed as to which of the two was to be
taken as the fundamental notion. The Epicurean said: "To be
conscious that one's maxims lead to happiness is virtue"; the Stoic
said: "To be conscious of one's virtue is happiness. " With the former,
Prudence was equivalent to morality; with the latter, who chose a
higher designation for virtue, morality alone was true wisdom.

While we must admire the men who in such early times tried all
imaginable ways of extending the domain of philosophy, we must at
the same time lament that their acuteness was unfortunately misapplied
in trying to trace out identity between two extremely heterogeneous
notions, those of happiness and virtue. But it agrees with the
dialectical spirit of their times (and subtle minds are even now
sometimes misled in the same way) to get rid of irreconcilable
differences in principle by seeking to change them into a mere contest
about words, and thus apparently working out the identity of the
notion under different names, and this usually occurs in cases where
the combination of heterogeneous principles lies so deep or so high,
or would require so complete a transformation of the doctrines assumed
in the rest of the philosophical system, that men are afraid to
penetrate deeply into the real difference and prefer treating it as
a difference in questions of form.

{BOOK_2|CHAPTER_2 ^paragraph 5}

While both schools sought to trace out the identity of the practical
principles of virtue and happiness, they were not agreed as to the way
in which they tried to force this identity, but were separated
infinitely from one another, the one placing its principle on the side
of sense, the other on that of reason; the one in the consciousness of
sensible wants, the other in the independence of practical reason on
all sensible grounds of determination. According to the Epicurean, the
notion of virtue was already involved in the maxim: "To promote
one's own happiness"; according to the Stoics, on the other hand,
the feeling of happiness was already contained in the consciousness of
virtue. Now whatever is contained in another notion is identical
with part of the containing notion, but not with the whole, and
moreover two wholes may be specifically distinct, although they
consist of the same parts; namely if the parts are united into a whole
in totally different ways. The Stoic maintained that the virtue was
the whole summum bonum, and happiness only the consciousness of
possessing it, as making part of the state of the subject. The
Epicurean maintained that happiness was the whole summum bonum, and
virtue only the form of the maxim for its pursuit; viz. , the
rational use of the means for attaining it.

Now it is clear from the Analytic that the maxims of virtue and
those of private happiness are quite heterogeneous as to their supreme
practical principle, and, although they belong to one summum bonum
which together they make possible, yet they are so far from coinciding
that they restrict and check one another very much in the same
subject. Thus the question: "How is the summum bonum practically
possible? " still remains an unsolved problem, notwithstanding all
the attempts at coalition that have hitherto been made. The Analytic
has, however, shown what it is that makes the problem difficult to
solve; namely, that happiness and morality are two specifically
distinct elements of the summum bonum and, therefore, their
combination cannot be analytically cognised (as if the man that
seeks his own happiness should find by mere analysis of his conception
that in so acting he is virtuous, or as if the man that follows virtue
should in the consciousness of such conduct find that he is already
happy ipso facto), but must be a synthesis of concepts. Now since this
combination is recognised as a priori, and therefore as practically
necessary, and consequently not as derived from experience, so that
the possibility of the summum bonum does not rest on any empirical
principle, it follows that the deduction [legitimation] of this
concept must be transcendental. It is a priori (morally) necessary
to produce the summum bonum by freedom of will: therefore the
condition of its possibility must rest solely on a priori principles
of cognition.



I. The Antinomy of Practical Reason.



{BOOK_2|CHAPTER_2 ^paragraph 10}

In the summum bonum which is practical for us, i. e. , to be
realized by our will, virtue and happiness are thought as
necessarily combined, so that the one cannot be assumed by pure
practical reason without the other also being attached to it. Now this
combination (like every other) is either analytical or synthetical. It
has been shown that it cannot be analytical; it must then be
synthetical and, more particularly, must be conceived as the
connection of cause and effect, since it concerns a practical good,
i. e. , one that is possible by means of action; consequently either the
desire of happiness must be the motive to maxims of virtue, or the
maxim of virtue must be the efficient cause of happiness. The first is
absolutely impossible, because (as was proved in the Analytic)
maxims which place the determining principle of the will in the desire
of personal happiness are not moral at all, and no virtue can be
founded on them. But the second is also impossible, because the
practical connection of causes and effects in the world, as the result
of the determination of the will, does not depend upon the moral
dispositions of the will, but on the knowledge of the laws of nature
and the physical power to use them for one's purposes; consequently we
cannot expect in the world by the most punctilious observance of the
moral laws any necessary connection of happiness with virtue
adequate to the summum bonum. Now, as the promotion of this summum
bonum, the conception of which contains this connection, is a priori a
necessary object of our will and inseparably attached to the moral
law, the impossibility of the former must prove the falsity of the
latter. If then the supreme good is not possible by practical rules,
then the moral law also which commands us to promote it is directed to
vain imaginary ends and must consequently be false.



II. Critical Solution of the Antinomy of Practical Reason.



The antinomy of pure speculative reason exhibits a similar
conflict between freedom and physical necessity in the causality of
events in the world. It was solved by showing that there is no real
contradiction when the events and even the world in which they occur
are regarded (as they ought to be) merely as appearances; since one
and the same acting being, as an appearance (even to his own inner
sense), has a causality in the world of sense that always conforms
to the mechanism of nature, but with respect to the same events, so
far as the acting person regards himself at the same time as a
noumenon (as pure intelligence in an existence not dependent on the
condition of time), he can contain a principle by which that causality
acting according to laws of nature is determined, but which is
itself free from all laws of nature.
