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 not 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 selflove, 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 be 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 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 selfesteem; 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.
