It is obvious that in such a system no one could
arbitrarily put an end to his own life, for such an arrangement
would not be a permanent order of things. And so in all similar cases.
Now, in nature, as it actually is an object of experience, the free
will is not of itself determined to maxims which could of themselves
be the foundation of a natural system of universal laws, or which
could even be adapted to a system so constituted; on the contrary, its
maxims are private inclinations which constitute, indeed, a natural
whole in conformity with pathological (physical) laws, but could not
form part of a system of nature, which would only be possible
through our will acting in accordance with pure practical laws. Yet we
are, through reason, conscious of a law to which all our maxims are
subject, as though a natural order must be originated from our will.
This law, therefore, must be the idea of a natural system not given in
experience, and yet possible through freedom; a system, therefore,
which is supersensible, and to which we give objective reality, at
least in a practical point of view, since we look on it as an object
of our will as pure rational beings.

Hence the distinction between the laws of a natural system to
which the will is subject, and of a natural system which is subject to
a will (as far as its relation to its free actions is concerned),
rests on this, that in the former the objects must be causes of the
ideas which determine the will; whereas in the latter the will is
the cause of the objects; so that its causality has its determining
principle solely in the pure faculty of reason, which may therefore be
called a pure practical reason.

There are therefore two very distinct problems: how, on the one
side, pure reason can cognise objects a priori, and how on the other
side it can be an immediate determining principle of the will, that
is, of the causality of the rational being with respect to the reality
of objects (through the mere thought of the universal validity of
its own maxims as laws).

{BOOK_1|CHAPTER_1 ^paragraph 135}

The former, which belongs to the critique of the pure speculative
reason, requires a previous explanation, how intuitions without
which no object can be given, and, therefore, none known
synthetically, are possible a priori; and its solution turns out to be
that these are all only sensible and, therefore, do not render
possible any speculative knowledge which goes further than possible
experience reaches; and that therefore all the principles of that pure
speculative reason avail only to make experience possible; either
experience of given objects or of those that may be given ad
infinitum, but never are completely given.

The latter, which belongs to the critique of practical reason,
requires no explanation how the objects of the faculty of desire are
possible, for that being a problem of the theoretical knowledge of
nature is left to the critique of the speculative reason, but only how
reason can determine the maxims of the will; whether this takes
place only by means of empirical ideas as principles of determination,
or whether pure reason can be practical and be the law of a possible
order of nature, which is not empirically knowable. The possibility of
such a supersensible system of nature, the conception of which can
also be the ground of its reality through our own free will, does
not require any a priori intuition (of an intelligible world) which,
being in this case supersensible, would be impossible for us. For
the question is only as to the determining principle of volition in
its maxims, namely, whether it is empirical, or is a conception of the
pure reason (having the legal character belonging to it in general),
and how it can be the latter. It is left to the theoretic principles
of reason to decide whether the causality of the will suffices for the
realization of the objects or not, this being an inquiry into the
possibility of the objects of the volition. Intuition of these objects
is therefore of no importance to the practical problem. We are here
concerned only with the determination of the will and the
determining principles of its maxims as a free will, not at all with
the result. For, provided only that the will conforms to the law of
pure reason, then let its power in execution be what it may, whether
according to these maxims of legislation of a possible system of
nature any such system really results or not, this is no concern of
the critique, which only inquires whether, and in what way, pure
reason can be practical, that is directly determine the will.

In this inquiry criticism may and must begin with pure practical
laws and their reality. But instead of intuition it takes as their
foundation the conception of their existence in the intelligible
world, namely, the concept of freedom. For this concept has no other
meaning, and these laws are only possible in relation to freedom of
the will; but freedom being supposed, they are necessary; or
conversely freedom is necessary because those laws are necessary,
being practical postulates. It cannot be further explained how this
consciousness of the moral law, or, what is the same thing, of
freedom, is possible; but that it is admissible is well established in
the theoretical critique.

The exposition of the supreme principle of practical reason is now
finished; that is to say, it has been shown first, what it
contains, that it subsists for itself quite a priori and independent
of empirical principles; and next in what it is distinguished from all
other practical principles. With the deduction, that is, the
justification of its objective and universal validity, and the
discernment of the possibility of such a synthetical proposition a
priori, we cannot expect to succeed so well as in the case of the
principles of pure theoretical reason. For these referred to objects
of possible experience, namely, to phenomena, and we could prove
that these phenomena could be known as objects of experience only by
being brought under the categories in accordance with these laws;
and consequently that all possible experience must conform to these
laws. But I could not proceed in this way with the deduction of the
moral law. For this does not concern the knowledge of the properties
of objects, which may be given to the reason from some other source;
but a knowledge which can itself be the ground of the existence of the
objects, and by which reason in a rational being has causality,
i. e. , pure reason, which can be regarded as a faculty immediately
determining the will.

Now all our human insight is at an end as soon as we have arrived at
fundamental powers or faculties, for the possibility of these cannot
be understood by any means, and just as little should it be
arbitrarily invented and assumed. Therefore, in the theoretic use of
reason, it is experience alone that can justify us in assuming them.
But this expedient of adducing empirical proofs, instead of a
deduction from a priori sources of knowledge, is denied us here in
respect to the pure practical faculty of reason. For whatever requires
to draw the proof of its reality from experience must depend for the
grounds of its possibility on principles of experience; and pure,
yet practical, reason by its very notion cannot be regarded as such.
Further, the moral law is given as a fact of pure reason of which we
are a priori conscious, and which is apodeictically certain, though it
be granted that in experience no example of its exact fulfilment can
be found. Hence, the objective reality of the moral law cannot be
proved by any deduction by any efforts of theoretical reason,
whether speculative or empirically supported, and therefore, even if
we renounced its apodeictic certainty, it could not be proved a
posteriori by experience, and yet it is firmly established of itself.

{BOOK_1|CHAPTER_1 ^paragraph 140}

But instead of this vainly sought deduction of the moral
principle, something else is found which was quite unexpected, namely,
that this moral principle serves conversely as the principle of the
deduction of an inscrutable faculty which no experience could prove,
but of which speculative reason was compelled at least to assume the
possibility (in order to find amongst its cosmological ideas the
unconditioned in the chain of causality, so as not to contradict
itself)- I mean the faculty of freedom. The moral law, which itself
does not require a justification, proves not merely the possibility of
freedom, but that it really belongs to beings who recognize this law
as binding on themselves. The moral law is in fact a law of the
causality of free agents and, therefore, of the possibility of a
supersensible system of nature, just as the metaphysical law of events
in the world of sense was a law of causality of the sensible system of
nature; and it therefore determines what speculative philosophy was
compelled to leave undetermined, namely, the law for a causality,
the concept of which in the latter was only negative; and therefore
for the first time gives this concept objective reality.

This sort of credential of the moral law, viz. , that it is set forth
as a principle of the deduction of freedom, which is a causality of
pure reason, is a sufficient substitute for all a priori
justification, since theoretic reason was compelled to assume at least
the possibility of freedom, in order to satisfy a want of its own. For
the moral law proves its reality, so as even to satisfy the critique
of the speculative reason, by the fact that it adds a positive
definition to a causality previously conceived only negatively, the
possibility of which was incomprehensible to speculative reason, which
yet was compelled to suppose it. For it adds the notion of a reason
that directly determines the will (by imposing on its maxims the
condition of a universal legislative form); and thus it is able for
the first time to give objective, though only practical, reality to
reason, which always became transcendent when it sought to proceed
speculatively with its ideas. It thus changes the transcendent use
of reason into an immanent use (so that reason is itself, by means
of ideas, an efficient cause in the field of experience).

The determination of the causality of beings in the world of
sense, as such, can never be unconditioned; and yet for every series
of conditions there must be something unconditioned, and therefore
there must be a causality which is determined wholly by itself. Hence,
the idea of freedom as a faculty of absolute spontaneity was not found
to be a want but, as far as its possibility is concerned, an
analytic principle of pure speculative reason. But as it is absolutely
impossible to find in experience any example in accordance with this
idea, because amongst the causes of things as phenomena it would be
impossible to meet with any absolutely unconditioned determination
of causality, we were only able to defend our supposition that a
freely acting cause might be a being in the world of sense, in so
far as it is considered in the other point of view as a noumenon,
showing that there is no contradiction in regarding all its actions as
subject to physical conditions so far as they are phenomena, and yet
regarding its causality as physically unconditioned, in so far as
the acting being belongs to the world of understanding, and in thus
making the concept of freedom the regulative principle of reason. By
this principle I do not indeed learn what the object is to which
that sort of causality is attributed; but I remove the difficulty,
for, on the one side, in the explanation of events in the world, and
consequently also of the actions of rational beings, I leave to the
mechanism of physical necessity the right of ascending from
conditioned to condition ad infinitum, while on the other side I
keep open for speculative reason the place which for it is vacant,
namely, the intelligible, in order to transfer the unconditioned
thither. But I was not able to verify this supposition; that is, to
change it into the knowledge of a being so acting, not even into the
knowledge of the possibility of such a being. This vacant place is now
filled by pure practical reason with a definite law of causality in an
intelligible world (causality with freedom), namely, the moral law.
Speculative reason does not hereby gain anything as regards its
insight, but only as regards the certainty of its problematical notion
of freedom, which here obtains objective reality, which, though only
practical, is nevertheless undoubted. Even the notion of causality-
the application, and consequently the signification, of which holds
properly only in relation to phenomena, so as to connect them into
experiences (as is shown by the Critique of Pure Reason)- is not so
enlarged as to extend its use beyond these limits. For if reason
sought to do this, it would have to show how the logical relation of
principle and consequence can be used synthetically in a different
sort of intuition from the sensible; that is how a causa noumenon is
possible. This it can never do; and, as practical reason, it does
not even concern itself with it, since it only places the
determining principle of causality of man as a sensible creature
(which is given) in pure reason (which is therefore called practical);
and therefore it employs the notion of cause, not in order to know
objects, but to determine causality in relation to objects in general.
It can abstract altogether from the application of this notion to
objects with a view to theoretical knowledge (since this concept is
always found a priori in the understanding even independently of any
intuition). Reason, then, employs it only for a practical purpose, and
hence we can transfer the determining principle of the will into the
intelligible order of things, admitting, at the same time, that we
cannot understand how the notion of cause can determine the
knowledge of these things. But reason must cognise causality with
respect to the actions of the will in the sensible world in a definite
manner; otherwise, practical reason could not really produce any
action. But as to the notion which it forms of its own causality as
noumenon, it need not determine it theoretically with a view to the
cognition of its supersensible existence, so as to give it
significance in this way. For it acquires significance apart from
this, though only for practical use, namely, through the moral law.
Theoretically viewed, it remains always a pure a priori concept of the
understanding, which can be applied to objects whether they have
been given sensibly or not, although in the latter case it has no
definite theoretical significance or application, but is only a
formal, though essential, conception of the understanding relating
to an object in general. The significance which reason gives it
through the moral law is merely practical, inasmuch as the idea of
the law of causality (of the will) has self causality, or is
its determining principle.



II. Of the Right that Pure Reason in its Practical use has to an
Extension which is not possible to it in its Speculative Use.

{BOOK_1|CHAPTER_1 ^paragraph 145}



We have in the moral principle set forth a law of causality, the
determining principle of which is set above all the conditions of
the sensible world; we have it conceived how the will, as belonging
to the intelligible world, is determinable, and therefore have
its subject (man) not merely conceived as belonging to a world of
pure understanding, and in this respect unknown (which the critique of
speculative reason enabled us to do), but also defined as regards
his causality by means of a law which cannot be reduced to any
physical law of the sensible world; and therefore our knowledge is
extended beyond the limits of that world, a pretension which the
Critique of Pure Reason declared to be futile in all speculation. Now,
how is the practical use of pure reason here to be reconciled with the
theoretical, as to the determination of the limits of its faculty?

David Hume, of whom we may say that he commenced the assault on
the claims of pure reason, which made a thorough investigation of it
necessary, argued thus: The notion of cause is a notion that
involves the necessity of the connexion of the existence of
different things (and that, in so far as they are different), so that,
given A, I know that something quite distinct there from, namely B,
must necessarily also exist. Now necessity can be attributed to a
connection, only in so far as it is known a priori, for experience
would only enable us to know of such a connection that it exists,
not that it necessarily exists. Now, it is impossible, says he, to
know a priori and as necessary the connection between one thing and
another (or between one attribute and another quite distinct) when
they have not been given in experience. Therefore the notion of a
cause is fictitious and delusive and, to speak in the mildest way,
is an illusion, only excusable inasmuch as the custom (a subjective
necessity) of perceiving certain things, or their attributes as
often associated in existence along with or in succession to one
another, is insensibly taken for an objective necessity of supposing
such a connection in the objects themselves; and thus the notion of
a cause has been acquired surreptitiously and not legitimately; nay,
it can never be so acquired or authenticated, since it demands a
connection in itself vain, chimerical, and untenable in presence of
reason, and to which no object can ever correspond. In this way was
empiricism first introduced as the sole source of principles, as far
as all knowledge of the existence of things is concerned
(mathematics therefore remaining excepted); and with empiricism the
most thorough scepticism, even with regard to the whole science of
nature( as philosophy). For on such principles we can never conclude
from given attributes of things as existing to a consequence (for this
would require the notion of cause, which involves the necessity of
such a connection); we can only, guided by imagination, expect similar
cases- an expectation which is never certain, however often it has
been fulfilled. Of no event could we say: a certain thing must have
preceded it, on which it necessarily followed; that is, it must have a
cause; and therefore, however frequent the cases we have known in
which there was such an antecedent, so that a rule could be derived
from them, yet we never could suppose it as always and necessarily
so happening; we should, therefore, be obliged to leave its share to
blind chance, with which all use of reason comes to an end; and this
firmly establishes scepticism in reference to arguments ascending from
effects to causes and makes it impregnable.

Mathematics escaped well, so far, because Hume thought that its
propositions were analytical; that is, proceeded from one property
to another, by virtue of identity and, consequently, according to
the principle of contradiction. This, however, is not the case, since,
on the contrary, they are synthetical; and although geometry, for
example, has not to do with the existence of things, but only with
their a priori properties in a possible intuition, yet it proceeds
just as in the case of the causal notion, from one property (A) to
another wholly distinct (B), as necessarily connected with the former.
Nevertheless, mathematical science, so highly vaunted for its
apodeictic certainty, must at last fall under this empiricism for
the same reason for which Hume put custom in the place of objective
necessity in the notion of cause and, in spite of all its pride,
must consent to lower its bold pretension of claiming assent a
priori and depend for assent to the universality of its propositions
on the kindness of observers, who, when called as witnesses, would
surely not hesitate to admit that what the geometer propounds as a
theorem they have always perceived to be the fact, and,
consequently, although it be not necessarily true, yet they would
permit us to expect it to be true in the future. In this manner Hume's
empiricism leads inevitably to scepticism, even with regard to
mathematics, and consequently in every scientific theoretical use of
reason (for this belongs either to philosophy or mathematics). Whether
with such a terrible overthrow of the chief branches of knowledge,
common reason will escape better, and will not rather become
irrecoverably involved in this destruction of all knowledge, so that
from the same principles a universal scepticism should follow
(affecting, indeed, only the learned), this I will leave everyone to
judge for himself.

As regards my own labours in the critical examination of pure
reason, which were occasioned by Hume's sceptical teaching, but went
much further and embraced the whole field of pure theoretical reason
in its synthetic use and, consequently, the field of what is called
metaphysics in general; I proceeded in the following manner with
respect to the doubts raised by the Scottish philosopher touching
the notion of causality. If Hume took the objects of experience for
things in themselves (as is almost always done), he was quite right in
declaring the notion of cause to be a deception and false illusion;
for as to things in themselves, and their attributes as such, it is
impossible to see why because A is given, B, which is different,
must necessarily be also given, and therefore he could by no means
admit such an a priori knowledge of things in themselves. Still less
could this acute writer allow an empirical origin of this concept,
since this is directly contradictory to the necessity of connection
which constitutes the essence of the notion of causality, hence the
notion was proscribed, and in its place was put custom in the
observation of the course of perceptions.

{BOOK_1|CHAPTER_1 ^paragraph 150}

It resulted, however, from my inquiries, that the objects with which
we have to do in experience are by no means things in themselves,
but merely phenomena; and that although in the case of things in
themselves it is impossible to see how, if A is supposed, it should be
contradictory that B, which is quite different from A, should not also
be supposed (i. e. , to see the necessity of the connection between A as
cause and B as effect); yet it can very well be conceived that, as
phenomena, they may be necessarily connected in one experience in a
certain way (e. g. , with regard to time-relations); so that they
could not be separated without contradicting that connection, by means
of which this experience is possible in which they are objects and
in which alone they are cognisable by us. And so it was found to be in
fact; so that I was able not only to prove the objective reality of
the concept of cause in regard to objects of experience, but also to
deduce it as an a priori concept by reason of the necessity of the
connection it implied; that is, to show the possibility of its
origin from pure understanding without any empirical sources; and
thus, after removing the source of empiricism, I was able also to
overthrow the inevitable consequence of this, namely, scepticism,
first with regard to physical science, and then with regard to
mathematics (in which empiricism has just the same grounds), both
being sciences which have reference to objects of possible experience;
herewith overthrowing the thorough doubt of whatever theoretic
reason professes to discern.

But how is it with the application of this category of causality
(and all the others; for without them there can be no knowledge of
anything existing) to things which are not objects of possible
experience, but lie beyond its bounds? For I was able to deduce the
objective reality of these concepts only with regard to objects of
possible experience. But even this very fact, that I have saved
them, only in case I have proved that objects may by means of them
be thought, though not determined a priori; this it is that gives them
a place in the pure understanding, by which they are referred to
objects in general (sensible or not sensible). If anything is still
wanting, it is that which is the condition of the application of these
categories, and especially that of causality, to objects, namely,
intuition; for where this is not given, the application with a view to
theoretic knowledge of the object, as a noumenon, is impossible and,
therefore, if anyone ventures on it, is (as in the Critique of Pure
Reason) absolutely forbidden. Still, the objective reality of the
concept (of causality) remains, and it can be used even of noumena,
but without our being able in the least to define the concept
theoretically so as to produce knowledge. For that this concept,
even in reference to an object, contains nothing impossible, was shown
by this, that, even while applied to objects of sense, its seat was
certainly fixed in the pure understanding; and although, when referred
to things in themselves (which cannot be objects of experience), it is
not capable of being determined so as to represent a definite object
for the purpose of theoretic knowledge; yet for any other purpose (for
instance, a practical) it might be capable of being determined so as
to have such application. This could not be the case if, as Hume
maintained, this concept of causality contained something absolutely
impossible to be thought.

In order now to discover this condition of the application of the
said concept to noumena, we need only recall why we are not content
with its application to objects of experience, but desire also to
apply it to things in themselves. It will appear, then, that it is not
a theoretic but a practical purpose that makes this a necessity. In
speculation, even if we were successful in it, we should not really
gain anything in the knowledge of nature, or generally with regard
to such objects as are given, but we should make a wide step from
the sensibly conditioned (in which we have already enough to do to
maintain ourselves, and to follow carefully the chain of causes) to
the supersensible, in order to complete our knowledge of principles
and to fix its limits; whereas there always remains an infinite
chasm unfilled between those limits and what we know; and we should
have hearkened to a vain curiosity rather than a solid-desire of
knowledge.

But, besides the relation in which the understanding stands to
objects (in theoretical knowledge), it has also a relation to the
faculty of desire, which is therefore called the will, and the pure
will, inasmuch as pure understanding (in this case called reason) is
practical through the mere conception of a law. The objective
reality of a pure will, or, what is the same thing, of a pure
practical reason, is given in the moral law a priori, as it were, by a
fact, for so we may name a determination of the will which is
inevitable, although it does not rest on empirical principles. Now, in
the notion of a will the notion of causality is already contained, and
hence the notion of a pure will contains that of a causality
accompanied with freedom, that is, one which is not determinable by
physical laws, and consequently is not capable of any empirical
intuition in proof of its reality, but, nevertheless, completely
justifies its objective reality a priori in the pure practical law;
not, indeed (as is easily seen) for the purposes of the theoretical,
but of the practical use of reason. Now the notion of a being that has
free will is the notion of a causa noumenon, and that this notion
involves no contradiction, we are already assured by the fact- that
inasmuch as the concept of cause has arisen wholly from pure
understanding, and has its objective reality assured by the deduction,
as it is moreover in its origin independent of any sensible
conditions, it is, therefore, not restricted to phenomena (unless we
wanted to make a definite theoretic use of it), but can be applied
equally to things that are objects of the pure understanding. But,
since this application cannot rest on any intuition (for intuition can
only be sensible), therefore, causa noumenon, as regards the theoretic
use of reason, although a possible and thinkable, is yet an empty
notion. Now, I do not desire by means of this to understand
theoretically the nature of a being, in so far as it has a pure
will; it is enough for me to have thereby designated it as such, and
hence to combine the notion of causality with that of freedom (and
what is inseparable from it, the moral law, as its determining
principle). Now, this right I certainly have by virtue of the pure,
not-empirical origin of the notion of cause, since I do not consider
myself entitled to make any use of it except in reference to the moral
law which determines its reality, that is, only a practical use.

If, with Hume, I had denied to the notion of causality all objective
reality in its [theoretic] use, not merely with regard to things in
themselves (the supersensible), but also with regard to the objects of
the senses, it would have lost all significance, and being a
theoretically impossible notion would have been declared to be quite
useless; and since what is nothing cannot be made any use of, the
practical use of a concept theoretically null would have been
absurd. But, as it is, the concept of a causality free from
empirical conditions, although empty, i. e. , without any appropriate
intuition), is yet theoretically possible, and refers to an
indeterminate object; but in compensation significance is given to
it in the moral law and consequently in a practical sense. I have,
indeed, no intuition which should determine its objective theoretic
reality, but not the less it has a real application, which is
exhibited in concreto in intentions or maxims; that is, it has a
practical reality which can be specified, and this is sufficient to
justify it even with a view to noumena.

{BOOK_1|CHAPTER_1 ^paragraph 155}

Now, this objective reality of a pure concept of the understanding
in the sphere of the supersensible, once brought in, gives an
objective reality also to all the other categories, although only so
far as they stand in necessary connexion with the determining
principle of the will (the moral law); a reality only of practical
application, which has not the least effect in enlarging our
theoretical knowledge of these objects, or the discernment of their
nature by pure reason. So we shall find also in the sequel that
these categories refer only to beings as intelligences, and in them
only to the relation of reason to the will; consequently, always
only to the practical, and beyond this cannot pretend to any knowledge
of these beings; and whatever other properties belonging to the
theoretical representation of supersensible things may be brought into
connexion with these categories, this is not to be reckoned as
knowledge, but only as a right (in a practical point of view, however,
it is a necessity) to admit and assume such beings, even in the case
where we [conceive] supersensible beings (e. g. , God) according to
analogy, that is, a purely rational relation, of which we make a
practical use with reference to what is sensible; and thus the
application to the supersensible solely in a practical point of view
does not give pure theoretic reason the least encouragement to run
riot into the transcendent.

BOOK_1|CHAPTER_2

CHAPTER II. Of the Concept of an Object of Pure Practical Reason.



By a concept of the practical reason I understand the idea of an
object as an effect possible to be produced through freedom. To be
an object of practical knowledge, as such, signifies, therefore,
only the relation of the will to the action by which the object or its
opposite would be realized; and to decide whether something is an
object of pure practical reason or not is only to discern the
possibility or impossibility of willing the action by which, if we had
the required power (about which experience must decide), a certain
object would be realized. If the object be taken as the determining
principle of our desire, it must first be known whether it is
physically possible by the free use of our powers, before we decide
whether it is an object of practical reason or not. On the other hand,
if the law can be considered a priori as the determining principle
of the action, and the latter therefore as determined by pure
practical reason, the judgement whether a thing is an object of pure
practical reason or not does not depend at all on the comparison
with our physical power; and the question is only whether we should
will an action that is directed to the existence of an object, if
the object were in our power; hence the previous question is only as
the moral possibility of the action, for in this case it is not the
object, but the law of the will, that is the determining principle
of the action. The only objects of practical reason are therefore
those of good and evil. For by the former is meant an object
necessarily desired according to a principle of reason; by the
latter one necessarily shunned, also according to a principle of
reason.

If the notion of good is not to be derived from an antecedent
practical law, but, on the contrary, is to serve as its foundation, it
can only be the notion of something whose existence promises pleasure,
and thus determines the causality of the subject to produce it, that
is to say, determines the faculty of desire. Now, since it is
impossible to discern a priori what idea will be accompanied with
pleasure and what with pain, it will depend on experience alone to
find out what is primarily good or evil. The property of the
subject, with reference to which alone this experiment can be made, is
the feeling of pleasure and pain, a receptivity belonging to the
internal sense; thus that only would be primarily good with which
the sensation of pleasure is immediately connected, and that simply
evil which immediately excites pain. Since, however, this is opposed
even to the usage of language, which distinguishes the pleasant from
the good, the unpleasant from the evil, and requires that good and
evil shall always be judged by reason, and, therefore, by concepts
which can be communicated to everyone, and not by mere sensation,
which is limited to individual [subjects] and their susceptibility;
and, since nevertheless, pleasure or pain cannot be connected with any
idea of an object a priori, the philosopher who thought himself
obliged to make a feeling of pleasure the foundation of his
practical judgements would call that good which is a means to the
pleasant, and evil, what is a cause of unpleasantness and pain; for
the judgement on the relation of means to ends certainly belongs to
reason. But, although reason is alone capable of discerning the
connexion of means with their ends (so that the will might even be
defined as the faculty of ends, since these are always determining
principles of the desires), yet the practical maxims which would
follow from the aforesaid principle of the good being merely a
means, would never contain as the object of the will anything good
in itself, but only something good for something; the good would
always be merely the useful, and that for which it is useful must
always lie outside the will, in sensation. Now if this as a pleasant
sensation were to be distinguished from the notion of good, then there
would be nothing primarily good at all, but the good would have to
be sought only in the means to something else, namely, some
pleasantness.

It is an old formula of the schools: Nihil appetimus nisi sub
ratione boni; Nihil aversamur nisi sub ratione mali, and it is used
often correctly, but often also in a manner injurious to philosophy,
because the expressions boni and mali are ambiguous, owing to the
poverty of language, in consequence of which they admit a double
sense, and, therefore, inevitably bring the practical laws into
ambiguity; and philosophy, which in employing them becomes aware of
the different meanings in the same word, but can find no special
expressions for them, is driven to subtile distinctions about which
there is subsequently no unanimity, because the distinction could
not be directly marked by any suitable expression. *



* Besides this, the expression sub ratione boni is also ambiguous.
For it may mean: "We represent something to ourselves as good, when
and because we desire (will) it"; or "We desire something because we
represent it to ourselves as good," so that either the desire
determines the notion of the object as a good, or the notion of good
determines the desire (the will); so that in the first case sub
ratione boni would mean, "We will something under the idea of the
good"; in the second, "In consequence of this idea," which, as
determining the volition, must precede it.

{BOOK_1|CHAPTER_2 ^paragraph 5}



The German language has the good fortune to possess expressions
which do not allow this difference to be overlooked. It possesses
two very distinct concepts and especially distinct expressions for
that which the Latins express by a single word, bonum. For bonum it
has das Gute [good], and das Wohl [well, weal], for malum das Bose
[evil], and das Ubel [ill, bad], or das Well [woe]. So that we express
two quite distinct judgements when we consider in an action the good
and evil of it, or our weal and woe (ill). Hence it already follows
that the above quoted psychological proposition is at least very
doubtful if it is translated: "We desire nothing except with a view to
our weal or woe"; on the other hand, if we render it thus: "Under
the direction of reason we desire nothing except so far as we esteem
it good or evil," it is indubitably certain and at the same time quite
clearly expressed.

Well or ill always implies only a reference to our condition, as
pleasant or unpleasant, as one of pleasure or pain, and if we desire
or avoid an object on this account, it is only so far as it is
referred to our sensibility and to the feeling of pleasure or pain
that it produces. But good or evil always implies a reference to the
will, as determined by the law of reason, to make something its
object; for it is never determined directly by the object and the idea
of it, but is a faculty of taking a rule of reason for or motive of an
action (by which an object may be realized). Good and evil therefore
are properly referred to actions, not to the sensations of the person,
and if anything is to be good or evil absolutely (i. e. , in every
respect and without any further condition), or is to be so esteemed,
it can only be the manner of acting, the maxim of the will, and
consequently the acting person himself as a good or evil man that
can be so called, and not a thing.

However, then, men may laugh at the Stoic, who in the severest
paroxysms of gout cried out: "Pain, however thou tormentest me, I will
never admit that thou art an evil (kakov, malum)": he was right. A bad
thing it certainly was, and his cry betrayed that; but that any evil
attached to him thereby, this he had no reason whatever to admit,
for pain did not in the least diminish the worth of his person, but
only that of his condition. If he had been conscious of a single
lie, it would have lowered his pride, but pain served only to raise
it, when he was conscious that he had not deserved it by any
unrighteous action by which he had rendered himself worthy of
punishment.

What we call good must be an object of desire in the judgement of
every rational man, and evil an object of aversion in the eyes of
everyone; therefore, in addition to sense, this judgement requires
reason. So it is with truthfulness, as opposed to lying; so with
justice, as opposed to violence, &c. But we may call a thing a bad [or
ill] thing, which yet everyone must at the same time acknowledge to be
good, sometimes directly, sometimes indirectly. The man who submits to
a surgical operation feels it no doubt as a bad thing, but by their
reason he and everyone acknowledge it to be good. If a man who
delights in annoying and vexing peaceable people at last receives a
right good beating, this is no doubt a bad thing; but everyone
approves it and regards it as a good thing, even though nothing else
resulted from it; nay, even the man who receives it must in his reason
acknowledge that he has met justice, because he sees the proportion
between good conduct and good fortune, which reason inevitably
places before him, here put into practice.

{BOOK_1|CHAPTER_2 ^paragraph 10}

No doubt our weal and woe are of very great importance in the
estimation of our practical reason, and as far as our nature as
sensible beings is concerned, our happiness is the only thing of
consequence, provided it is estimated as reason especially requires,
not by the transitory sensation, but by the influence that this has on
our whole existence, and on our satisfaction therewith; but it is
not absolutely the only thing of consequence. Man is a being who, as
belonging to the world of sense, has wants, and so far his reason
has an office which it cannot refuse, namely, to attend to the
interest of his sensible nature, and to form practical maxims, even
with a view to the happiness of this life, and if possible even to
that of a future. But he is not so completely an animal as to be
indifferent to what reason says on its own account, and to use it
merely as an instrument for the satisfaction of his wants as a
sensible being. For the possession of reason would not raise his worth
above that of the brutes, if it is to serve him only for the same
purpose that instinct serves in them; it would in that case be only
a particular method which nature had employed to equip man for the
same ends for which it has qualified brutes, without qualifying him
for any higher purpose. No doubt once this arrangement of nature has
been made for him he requires reason in order to take into
consideration his weal and woe, but besides this he possesses it for a
higher purpose also, namely, not only to take into consideration
what is good or evil in itself, about which only pure reason,
uninfluenced by any sensible interest, can judge, but also to
distinguish this estimate thoroughly from the former and to make it
the supreme condition thereof.

In estimating what is good or evil in itself, as distinguished
from what can be so called only relatively, the following points are
to be considered. Either a rational principle is already conceived, as
of itself the determining principle of the will, without regard to
possible objects of desire (and therefore by the more legislative form
of the maxim), and in that case that principle is a practical a priori
law, and pure reason is supposed to be practical of itself. The law in
that case determines the will directly; the action conformed to it
is good in itself; a will whose maxim always conforms to this law is
good absolutely in every respect and is the supreme condition of all
good. Or the maxim of the will is consequent on a determining
principle of desire which presupposes an object of pleasure or pain,
something therefore that pleases or displeases, and the maxim of
reason that we should pursue the former and avoid the latter
determines our actions as good relatively to our inclination, that is,
good indirectly, (i. e. , relatively to a different end to which they are
means), and in that case these maxims can never be called laws, but
may be called rational practical precepts. The end itself, the
pleasure that we seek, is in the latter case not a good but a welfare;
not a concept of reason, but an empirical concept of an object of
sensation; but the use of the means thereto, that is, the action, is
nevertheless called good (because rational deliberation is required
for it), not however, good absolutely, but only relatively to our
sensuous nature, with regard to its feelings of pleasure and
displeasure; but the will whose maxim is affected thereby is not a
pure will; this is directed only to that in which pure reason by
itself can be practical.

This is the proper place to explain the paradox of method in a
critique of practical reason, namely, that the concept of good and
evil must not be determined before the moral law (of which it seems as
if it must be the foundation), but only after it and by means of it.
In fact, even if we did not know that the principle of morality is a
pure a priori law determining the will, yet, that we may not assume
principles quite gratuitously, we must, at least at first, leave it
undecided, whether the will has merely empirical principles of
determination, or whether it has not also pure a priori principles;
for it is contrary to all rules of philosophical method to assume as
decided that which is the very point in question. Supposing that we
wished to begin with the concept of good, in order to deduce from it
the laws of the will, then this concept of an object (as a good) would
at the same time assign to us this object as the sole determining
principle of the will. Now, since this concept had not any practical a
priori law for its standard, the criterion of good or evil could not
be placed in anything but the agreement of the object with our feeling
of pleasure or pain; and the use of reason could only consist in
determining in the first place this pleasure or pain in connexion with
all the sensations of my existence, and in the second place the
means of securing to myself the object of the pleasure. Now, as
experience alone can decide what conforms to the feeling of
pleasure, and by hypothesis the practical law is to be based on this
as a condition, it follows that the possibility of a priori
practical laws would be at once excluded, because it was imagined to
be necessary first of all to find an object the concept of which, as a
good, should constitute the universal though empirical principle of
determination of the will. But what it was necessary to inquire
first of all was whether there is not an a priori determining
principle of the will (and this could never be found anywhere but in a
pure practical law, in so far as this law prescribes to maxims
merely their form without regard to an object). Since, however, we
laid the foundation of all practical law in an object determined by
our conceptions of good and evil, whereas without a previous law
that object could not be conceived by empirical concepts, we have
deprived ourselves beforehand of the possibility of even conceiving
a pure practical law. On the other hand, if we had first
investigated the latter analytically, we should have found that it
is not the concept of good as an object that determines the moral
law and makes it possible, but that, on the contrary, it is the
moral law that first determines the concept of good and makes it
possible, so far as it deserves the name of good absolutely.

This remark, which only concerns the method of ultimate ethical
inquiries, is of importance. It explains at once the occasion of all
the mistakes of philosophers with respect to the supreme principle
of morals. For they sought for an object of the will which they
could make the matter and principle of a law (which consequently could
not determine the will directly, but by means of that object
referred to the feeling of pleasure or pain; whereas they ought
first to have searched for a law that would determine the will a
priori and directly, and afterwards determine the object in accordance
with the will). Now, whether they placed this object of pleasure,
which was to supply the supreme conception of goodness, in
happiness, in perfection, in moral [feeling], or in the will of God,
their principle in every case implied heteronomy, and they must
inevitably come upon empirical conditions of a moral law, since
their object, which was to be the immediate principle of the will,
could not be called good or bad except in its immediate relation to
feeling, which is always empirical. It is only a formal law- that
is, one which prescribes to reason nothing more than the form of its
universal legislation as the supreme condition of its maxims- that can
be a priori a determining principle of practical reason. The
ancients avowed this error without concealment by directing all
their moral inquiries to the determination of the notion of the summum
bonum, which they intended afterwards to make the determining
principle of the will in the moral law; whereas it is only far
later, when the moral law has been first established for itself, and
shown to be the direct determining principle of the will, that this
object can be presented to the will, whose form is now determined a
priori; and this we shall undertake in the Dialectic of the pure
practical reason. The moderns, with whom the question of the summum
bonum has gone out of fashion, or at least seems to have become a
secondary matter, hide the same error under vague (expressions as in
many other cases). It shows itself, nevertheless, in their systems, as
it always produces heteronomy of practical reason; and from this can
never be derived a moral law giving universal commands.

Now, since the notions of good and evil, as consequences of the a
priori determination of the will, imply also a pure practical
principle, and therefore a causality of pure reason; hence they do not
originally refer to objects (so as to be, for instance, special
modes of the synthetic unity of the manifold of given intuitions in
one consciousness) like the pure concepts of the understanding or
categories of reason in its theoretic employment; on the contrary,
they presuppose that objects are given; but they are all modes
(modi) of a single category, namely, that of causality, the
determining principle of which consists in the rational conception
of a law, which as a law of freedom reason gives to itself, thereby
a priori proving itself practical. However, as the actions on the
one side come under a law which is not a physical law, but a law of
freedom, and consequently belong to the conduct of beings in the world
of intelligence, yet on the other side as events in the world of sense
they belong to phenomena; hence the determinations of a practical
reason are only possible in reference to the latter and, therefore, in
accordance with the categories of the understanding; not indeed with a
view to any theoretic employment of it, i. e. , so as to bring the
manifold of (sensible) intuition under one consciousness a priori; but
only to subject the manifold of desires to the unity of
consciousness of a practical reason, giving it commands in the moral
law, i. e. , to a pure will a priori.

{BOOK_1|CHAPTER_2 ^paragraph 15}

These categories of freedom- for so we choose to call them in
contrast to those theoretic categories which are categories of
physical nature- have an obvious advantage over the latter, inasmuch
as the latter are only forms of thought which designate objects in
an indefinite manner by means of universal concept of every possible
intuition; the former, on the contrary, refer to the determination
of a free elective will (to which indeed no exactly corresponding
intuition can be assigned, but which has as its foundation a pure
practical a priori law, which is not the case with any concepts
belonging to the theoretic use of our cognitive faculties); hence,
instead of the form of intuition (space and time), which does not
lie in reason itself, but has to be drawn from another source, namely,
the sensibility, these being elementary practical concepts have as
their foundation the form of a pure will, which is given in reason
and, therefore, in the thinking faculty itself. From this it happens
that as all precepts of pure practical reason have to do only with the
determination of the will, not with the physical conditions (of
practical ability) of the execution of one's purpose, the practical
a priori principles in relation to the supreme principle of freedom
are at once cognitions, and have not to wait for intuitions in order
to acquire significance, and that for this remarkable reason,
because they themselves produce the reality of that to which they
refer (the intention of the will), which is not the case with
theoretical concepts. Only we must be careful to observe that these
categories only apply to the practical reason; and thus they proceed
in order from those which are as yet subject to sensible conditions
and morally indeterminate to those which are free from sensible
conditions and determined merely by the moral law.

{BOOK_1|CHAPTER_2 ^paragraph 40}

It will at once be observed that in this table freedom is considered
as a sort of causality not subject to empirical principles of
determination, in regard to actions possible by it, which are
phenomena in the world of sense, and that consequently it is
referred to the categories which concern its physical possibility,
whilst yet each category is taken so universally that the
determining principle of that causality can be placed outside the
world of sense in freedom as a property of a being in the world of
intelligence; and finally the categories of modality introduce the
transition from practical principles generally to those of morality,
but only problematically. These can be established dogmatically only
by the moral law.

I add nothing further here in explanation of the present table,
since it is intelligible enough of itself. A division of this kind
based on principles is very useful in any science, both for the sake
of thoroughness and intelligibility. Thus, for instance, we know
from the preceding table and its first number what we must begin
from in practical inquiries; namely, from the maxims which every one
founds on his own inclinations; the precepts which hold for a
species of rational beings so far as they agree in certain
inclinations; and finally the law which holds for all without regard
to their inclinations, etc. In this way we survey the whole plan of
what has to be done, every question of practical philosophy that has
to be answered, and also the order that is to be followed.



Of the Typic of the Pure Practical Judgement.
{BOOK_1|CHAPTER_2 ^paragraph 45}

It is the notions of good and evil that first determine an object of
the will. They themselves, however, are subject to a practical rule of
reason which, if it is pure reason, determines the will a priori
relatively to its object. Now, whether an action which is possible
to us in the world of sense, comes under the rule or not, is a
question to be decided by the practical judgement, by which what is
said in the rule universally (in abstracto) is applied to an action in
concreto. But since a practical rule of pure reason in the first place
as practical concerns the existence of an object, and in the second
place as a practical rule of pure reason implies necessity as
regards the existence of the action and, therefore, is a practical
law, not a physical law depending on empirical principles of
determination, but a law of freedom by which the will is to be
determined independently on anything empirical (merely by the
conception of a law and its form), whereas all instances that can
occur of possible actions can only be empirical, that is, belong to
the experience of physical nature; hence, it seems absurd to expect to
find in the world of sense a case which, while as such it depends only
on the law of nature, yet admits of the application to it of a law
of freedom, and to which we can apply the supersensible idea of the
morally good which is to be exhibited in it in concreto. Thus, the
judgement of the pure practical reason is subject to the same
difficulties as that of the pure theoretical reason. The latter,
however, had means at hand of escaping from these difficulties,
because, in regard to the theoretical employment, intuitions were
required to which pure concepts of the understanding could be applied,
and such intuitions (though only of objects of the senses) can be
given a priori and, therefore, as far as regards the union of the
manifold in them, conforming to the pure a priori concepts of the
understanding as schemata. On the other hand, the morally good is
something whose object is supersensible; for which, therefore, nothing
corresponding can be found in any sensible intuition. 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.

BOOK_1|CHAPTER_3

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
