Hence all these relative ends can give rise only
to hypothetical imperatives.

Supposing, however, that there were something whose existence has in
itself an absolute worth, something which, being an end in itself,
could be a source of definite laws, then in this and this alone
would He the source of a possible categorical imperative, i. e. , a
practical law.

Now I say: man and generally any rational being exists as an end in
himself, not merely as a means to be arbitrarily used by this or
that will, but in all his actions, whether they concern himself or
other rational beings, must be always regarded at the same time as
an end. All objects of the inclinations have only a conditional
worth, for if the inclinations and the wants founded on them did not
exist, then their object would be without value. But the
inclinations themselves being sources of want, are so far from
having an absolute worth for which they should be desired, that on
the contrary it must be the universal wish of every rational being
to be wholly free from them. Thus the worth of any object which is
to be acquired by our action is always conditional. Beings whose
existence depends not on our will but on nature's, have
nevertheless, if they are irrational beings, only a relative value
as means, and are therefore called things; rational beings, on the
contrary, are called persons, because their very nature points them
out as ends in themselves, that is as something which must not be
used merely as means, and so far therefore restricts freedom of
action (and is an object of respect). These, therefore, are not
merely subjective ends whose existence has a worth for us as an
effect of our action but objective ends, that is things whose
existence is an end in itself: an end moreover for which no other
can be substituted, which they should subserve merely as means, for
otherwise nothing whatever would possess absolute worth; but if all
worth were conditioned and therefore contingent, then there would be
no supreme practical principle of reason whatever.

If then there is a supreme practical principle or, in respect of the
human will, a categorical imperative, it must be one which, being
drawn from the conception of that which is necessarily an end for
every one because it is an end in itself, constitutes an objective
principle of will, and can therefore serve as a universal practical
law. The foundation of this principle is: rational nature exists as
an end in itself. Man necessarily conceives his own existence as
being so; so far then this is a subjective principle of human
actions. But every other rational being regards its existence
similarly, just on the same rational principle that holds for me:
[Footnote: This proposition is here stated as a postulate. The
grounds of it will be found in the concluding section. ] so that it
is at the same time an objective principle, from which as a supreme
practical law all laws of the will must be capable of being deduced.
Accordingly the practical imperative will be as follows: So act as
to treat humanity, whether in thine own person or in that of any
other, in every case as an end withal, never as means only. We will
now inquire whether this can be practically carried out.

To abide by the previous examples:

Firstly, under the head of necessary duty to oneself: He who
contemplates suicide should ask himself whether his action can be
consistent with the idea of humanity as an end in itself. If he
destroys himself in order to escape from painful circumstances, he
uses a person merely as a mean to maintain a tolerable condition up
to the end of life. But a man is not a thing, that is to say,
something which can be used merely as means, but must in all his
actions be always considered as an end in himself. I cannot,
therefore, dispose in any way of a man in my own person so as to
mutilate him, to damage or kill him. (It belongs to ethics proper to
define this principle more precisely so as to avoid all
misunderstanding, e. g. , as to the amputation of the limbs in order
to preserve myself; as to exposing my life to danger with a view to
preserve it, &c. This question is therefore omitted here. )

Secondly, as regards necessary duties, or those of strict
obligation, towards others; he who is thinking of making a lying
promise to others will see at once that he would be using another
man merely as a mean, without the latter containing at the same time
the end in himself. For he whom I propose by such a promise to use
for my own purposes cannot possibly assent to my mode of acting
towards him, and therefore cannot himself contain the end of this
action. This violation of the principle of humanity in other men is
more obvious if we take in examples of attacks on the freedom and
property of others. For then it is clear that he who transgresses
the rights of men, intends to use the person of others merely as
means, without considering that as rational beings they ought always
to be esteemed also as ends, that is, as beings who must be capable
of containing in themselves the end of the very same action.
[Footnote: Let it not be thought that the common: quod tibi non vis
fieri, &c. , could serve here as the rule or principle. For it is
only a deduction from the former, though with several limitations;
it cannot be a universal law, for it does not contain the principle
of duties to oneself, nor of the duties of benevolence to others
(for many a one would gladly consent that others should not benefit
him, provided only that he might be excused from showing benevolence
to them), nor finally that of duties of strict obligation to one
another, for on this principle the criminal might argue against the
judge who punishes him, and so on. ]

Thirdly, as regards contingent (meritorious) duties to oneself; it
is not enough that the action does not violate humanity in our own
person as an end in itself, it must also harmonise with it. Now
there are in humanity capacities of greater perfection which belong
to the end that nature has in view in regard to humanity in
ourselves as the subject: to neglect these might perhaps be
consistent with the maintenance of humanity as an end in itself, but
not with the advancement of this end.

Fourthly, as regards meritorious duties towards others: the natural
end which all men have in their own happiness. Now humanity might
indeed subsist, although no one should contribute anything to the
happiness of others, provided he did not intentionally withdraw
anything from it; but after all, this would only harmonise
negatively not positively with humanity as an end in itself, if
everyone does not also endeavor, as far as in him lies, to forward
the ends of others. For the ends of any subject which is an end in
himself, ought as far as possible to be my ends also, if that
conception is to have its full effect with me.

This principle, that humanity and generally every rational nature is
an end in itself (which is the supreme limiting condition of every
man's freedom of action), is not borrowed from experience, firstly,
because it is universal, applying as it does to all rational beings
whatever, and experience is not capable of determining anything
about them; secondly, because it does not present humanity as an end
to men (subjectively), that is as an object which men do of
themselves actually adopt as an end; but as an objective end, which
must as a law constitute the supreme limiting condition of all our
subjective ends, let them be what we will; it must therefore spring
from pure, reason. In fact the objective principle of all practical
legislation lies (according to the first principle) in the rule and
its form of universality which makes it capable of being a law (say,
e. g. , a law of nature); but the subjective principle is in the end;
now by the second principle the subject of all ends is each rational
being, inasmuch as it is an end in itself. Hence follows the third
practical principle of the will, which is the ultimate condition of
its harmony with the universal practical reason, viz. : the idea of
the will of every rational being as a universally legislative will.

On this principle all maxims are rejected which are inconsistent
with the will being itself universal legislator. Thus the will is
not subject simply to the law, but so subject that it must be
regarded as itself giving the law, and on this ground only, subject
to the law (of which it can regard itself as the author).

In the previous imperatives, namely, that based on the conception of
the conformity of actions to general laws, as in a physical system
of nature, and that based on the universal prerogative of rational
beings as ends in themselves--these imperatives just because they
were conceived as categorical, excluded from any share in their
authority all admixture of any interest as a spring of action; they
were however only assumed to be categorical, because such an
assumption was necessary to explain the conception of duty. But we
could not prove independently that there are practical propositions
which command categorically, nor can it be proved in this section;
one thing however could be done, namely, to indicate in the
imperative itself by some determinate expression, that in the case
of volition from duty all interest is renounced, which is the
specific criterion of categorical as distinguished from hypothetical
imperatives. This is done in the present (third) formula of the
principle, namely, in the idea of the will of every rational being
as a universally legislating will.

For although a will which is subject to laws may be attached to this
law by means of an interest, yet a will which is itself a supreme
lawgiver so far as it is such cannot possibly depend on any
interest, since a will so dependent would itself still need another
law restricting the interest of its self-love by the condition that
it should be valid as universal law.

Thus the principle that every human will is a will which in all its
maxims gives universal laws [Footnote: I may be excused from
adducing examples to elucidate this principle, as those which have
already been used to elucidate the categorical imperative and its
formula would all serve for the like purpose here. ] provided it be
otherwise justified, would be very well adapted to be the
categorical imperative, in this respect, namely, that just because
of the idea of universal legislation it is not based on any
interest, and therefore it alone among all possible imperatives can
be unconditional. Or still better, converting the proposition, if
there is a categorical imperative (i. e. a law for the will of every
rational being), it can only command that everything be done from
maxims of one's will regarded as a will which could at the same time
will that it should itself give universal laws, for in that case
only the practical principle and the imperative which it obeys are
unconditional, since they cannot be based on any interest.

Looking back now on all previous attempts to discover the principle
of morality, we need not wonder why they all fail. It was seen that
man was bound to laws by duty, but it was not observed that the laws
to which he is subject are only those of his own giving, though at
the same time they are universal, and that he is only bound to act
in conformity with his own will; a will, however, which is designed
by nature to give universal laws. For when one has conceived man
only as subject to a law (no matter what), then this law required
some interest, either by way of attraction or constraint, since it
did not originate as a law from his own will, but this will was
according to a law obliged by something else to act in a certain
manner. Now by this necessary consequence all the labour spent in
finding a supreme principle of duty was irrevocably lost. For men
never elicited duty, but only a necessity of acting from a certain
interest. Whether this interest was private or otherwise, in any
case the imperative must be conditional, and could not by any means
be capable of being a moral command. I will therefore call this the
principle of Autonomy of the will, in contrast with every other
which I accordingly reckon as Heteronomy? [Footnote: Cp. "Critical
Examination of Practical Reason," p. 184. ]

The conception of every rational being as one which must consider
itself as giving in all the maxims of its will universal laws, so as
to judge itself and its actions from this point of view--this
conception leads to another which depends on it and is very
fruitful, namely, that of a kingdom of ends.

By a kingdom I understand the union of different rational beings in
a system by common laws. Now since it is by laws that ends are
determined as regards their universal validity, hence, if we
abstract from the personal differences of rational beings, and
likewise from all the content of their private ends, we shall be
able to conceive all ends combined in a systematic whole (including
both rational beings as ends in themselves, and also the special
ends which each may propose to himself), that is to say, we can
conceive a kingdom of ends, which on the preceding principles is
possible.

For all rational beings come under the law that each of them must
treat itself and all others never merely as means, but in every case
at the same time as ends in themselves. Hence results a systematic
union of rational beings by common objective laws, i. e. a kingdom
which may be called a kingdom of ends, since what these laws have in
view is just the relation of these beings to one another as ends and
means. It is certainly only an ideal.

A rational being belongs as a member to the kingdom of ends when,
although giving universal laws in it, he is also himself subject to
these laws. He belongs to it as sovereign when, while giving laws,
he is not subject to the will of any other.

A rational being must always regard himself as giving laws either as
member or as sovereign in a kingdom of ends which is rendered
possible by the freedom of will. He cannot, however, maintain the
latter position merely by the maxims of his will, but only in case
he is a completely independent being without wants and with
unrestricted power adequate to his will.

Morality consists then in the reference of all action to the
legislation which alone can render a kingdom of ends possible. This
legislation must be capable of existing in every rational being, and
of emanating from his will, so that the principle of this will is,
never to act on any maxim which could not without contradiction be
also a universal law, and accordingly always so to act that the will
could at the same time regard itself as giving in its maxims
universal laws. If now the maxims of rational beings are not by
their own nature coincident with this objective principle, then the
necessity of acting on it is called practical necessitation, i. e. ,
duty. Duty does not apply to the sovereign in the kingdom of ends,
but it does to every member of it and to all in the same degree.

The practical necessity of acting on this principle, i. e. , duty,
does not rest at all on feelings, impulses, or inclinations, but
solely on the relation of rational beings to one another, a relation
in which the will of a rational being must always be regarded as
legislative, since otherwise it could not be conceived as an end in
itself. Reason then refers every maxim of the will, regarding it as
legislating universally, to every other will and also to every
action towards oneself; and this not on account of any other
practical motive or any future advantage, but from the idea of the
dignity of a rational being, obeying no law but that which he
himself also gives.

In the kingdom of ends everything has either Value or Dignity.
Whatever has a value can be replaced by something else which is
equivalent; whatever, on the other hand, is above all value, and
therefore admits of no equivalent, has a dignity.

Whatever has reference to the general inclinations and wants of
mankind has a market value; whatever, without presupposing a want,
corresponds to a certain taste, that is to a satisfaction in the
mere purposeless play of our faculties, has a fancy value; but that
which constitutes the condition under which alone anything can be an
end in itself, this has not merely a relative worth, i. e. , value,
but an intrinsic worth, that is dignity.

Now morality is the condition under which alone a rational being can
be an end in himself, since by this alone it is possible that he
should be a legislating member in the kingdom of ends. Thus
morality, and humanity as capable of it, is that which alone has
dignity. Skill and diligence in labour have a market value; wit,
lively imagination, and humour, have fancy value; on the other hand,
fidelity to promises, benevolence from principle (not from
instinct), have an intrinsic worth. Neither nature nor art contains
anything which in default of these it could put in their place, for
their worth consists not in the effects which spring from them, not
in the use and advantage which they secure, but in the disposition
of mind, that is, the maxims of the will which are ready to manifest
themselves in such actions, even though they should not have the
desired effect. These actions also need no recommendation from any
subjective taste or sentiment, that they may be looked on with
immediate favour and satisfaction: they need no immediate propension
or feeling for them; they exhibit the will that performs them as an
object of an immediate respect, and nothing but reason is required
to IMPOSE them on the will; not to FLATTER it into them, which, in
the case of duties, would be a contradiction. This estimation
therefore shows that the worth of such a disposition is dignity, and
places it infinitely above all value, with which it cannot for a
moment be brought into comparison or competition without as it were
violating its sanctity.

What then is it which justifies virtue or the morally good
disposition, in making such lofty claims? It is nothing less than
the privilege it secures to the rational being of participating in
the giving of universal laws, by which it qualifies him to be a
member of a possible kingdom of ends, a privilege to which he was
already destined by his own nature as being an end in himself, and
on that account legislating in the kingdom of ends; free as regards
all laws of physical nature, and obeying those only which he himself
gives, and by which his maxims can belong to a system of universal
law, to which at the same time he submits himself. For nothing has
any worth except what the law assigns it. Now the legislation itself
which assigns the worth of everything, must for that very reason
possess dignity, that is an unconditional incomparable worth, and
the word RESPECT alone supplies a becoming expression for the esteem
which a rational being must have for it. AUTONOMY then is the basis
of the dignity of human and of every rational nature.

The three modes of presenting the principle of morality that have
been adduced are at bottom only so many formulae of the very same
law, and each of itself involves the other two. There is, however, a
difference in them, but it is rather subjectively than objectively
practical, intended namely to bring an idea of the reason nearer to
intuition (by means of a certain analogy), and thereby nearer to
feeling. All maxims, in fact, have--

1. A FORM, consisting in universality; and in this view the formula
of the moral imperative is expressed thus, that the maxims must be
so chosen as if they were to serve as universal laws of nature.

2. A MATTER [Footnote: The reading "Maxima," which is that both of
Rosenkranz and Hartenstein, is obviously an error for "Materie. "]
namely, an end, and here the formula says that the rational being,
as it is an end by its own nature and therefore an end in itself,
must in every maxim serve as the condition limiting all merely
relative and arbitrary ends.

3. A COMPLETE CHARACTERISATION of all maxims by means of that
formula, namely, that all maxims ought by their own legislation to
harmonise with a possible kingdom of ends as with a kingdom of
nature. [Footnote: Teleology considers nature as a kingdom of ends;
Ethics regards a possible kingdom of ends as a kingdom of nature. In
the first case, the kingdom of ends is a theoretical idea, adopted
to explain what actually is. In the latter it is a practical idea,
adopted to bring about that which is not yet, but which can be
realised by our conduct, namely, if it conforms to this idea. ] There
is a progress here in the order of the categories of UNITY of the
form of the will (its universality), PLURALITY of the matter (the
objects, i. e. the ends), and TOTALITY of the system of these. In
forming our moral JUDGMENT of actions it is better to proceed always
on the strict method, and start from the general formula of the
categorical imperative: ACT ACCORDING TO A MAXIM WHICH CAN AT THE
SAME TIME MAKE ITSELF A UNIVERSAL LAW. If, however, we wish to gain
an ENTRANCE for the moral law, it is very useful to bring one and
the same action under the three specified conceptions, and thereby
as far as possible to bring it nearer to intuition.

We can now end where we started at the beginning, namely, with the
conception of a will unconditionally good. THAT WILL is ABSOLUTELY
GOOD which cannot be evil, in other words, whose maxim, if made a
universal law, could never contradict itself. This principle then is
its supreme law: Act always on such a maxim as thou canst at the
same time will to be a universal law; this is the sole condition
under which a will can never contradict itself; and such an
imperative is categorical. Since the validity of the will as a
universal law for possible actions is analogous to the universal
connexion of the existence of things by general laws, which is the
formal notion of nature in general, the categorical imperative can
also be expressed thus: ACT ON MAXIMS WHICH CAN AT THE SAME TIME
HAVE FOR THEIR OBJECT THEMSELVES AS UNIVERSAL LAWS OF NATURE. Such
then is the formula of an absolutely good will.

Rational nature is distinguished from the rest of nature by this,
that it sets before itself an end. This end would be the matter of
every good will. But since in the idea of a will that is absolutely
good without being limited by any condition (of attaining this or
that end) we must abstract wholly from every end TO BE EFFECTED
(since this would make every will only relatively good), it follows
that in this case the end must be conceived, not as an end to be
effected, but as an INDEPENDENTLY existing end. Consequently it is
conceived only negatively, i. e. , as that which we must never act
against, and which, therefore, must never be regarded merely as
means, but must in every volition be esteemed as an end likewise.
Now this end can be nothing but the subject of all possible ends,
since this is also the subject of a possible absolutely good will;
for such a will cannot without contradiction be postponed to any
other object. The principle: So act in regard to every rational
being (thyself and others), that he may always have place in thy
maxim as an end in himself, is accordingly essentially identical
with this other: Act upon a maxim which, at the same time, involves
its own universal validity for every rational being. For that in
using means for every end I should limit my maxim by the condition
of its holding good as a law for every subject, this comes to the
same thing as that the fundamental principle of all maxims of action
must be that the subject of all ends, i. e. , the rational being
himself, be never employed merely as means, but as the supreme
condition restricting the use of all means, that is in every case as
an end likewise.

It follows incontestably that, to whatever laws any rational being
may be subject, he being an end in himself must be able to regard
himself as also legislating universally in respect of these same
laws, since it is just this fitness of his maxims for universal
legislation that distinguishes him as an end in himself; also it
follows that this implies his dignity (prerogative) above all mere
physical beings, that he must always take his maxims from the point
of view which regards himself, and likewise every other rational
being, as lawgiving beings (on which account they are called
persons). In this way a world of rational beings (mundus
intelligibilis) is possible as a kingdom of ends, and this by virtue
of the legislation proper to all persons as members. Therefore every
rational being must so act as if he were by his maxims in every case
a legislating member in the universal kingdom of ends. The formal
principle of these maxims is: So act as if thy maxim were to serve
likewise as the universal law (of all rational beings). A kingdom of
ends is thus only possible on the analogy of a kingdom of nature,
the former however only by maxims, that is self-imposed rules, the
latter only by the laws of efficient causes acting under
necessitation from without. Nevertheless, although the system of
nature is looked upon as a machine, yet so far as it has reference
to rational beings as its ends, it is given on this account the name
of a kingdom of nature. Now such a kingdom of ends would be actually
realised by means of maxims conforming to the canon which the
categorical imperative prescribes to all rational beings, IF THEY
WERE UNIVERSALLY FOLLOWED. But although a rational being, even if he
punctually follows this maxim himself, cannot reckon upon all others
being therefore true to the same, nor expect that the kingdom of
nature and its orderly arrangements shall be in harmony with him as
a fitting member, so as to form a kingdom of ends to which he
himself contributes, that is to say, that it shall favour his
expectation of happiness, still that law: Act according to the
maxims of a member of a merely possible kingdom of ends legislating
in it universally, remains in its full force, inasmuch as it
commands categorically. And it is just in this that the paradox
lies; that the mere dignity of a man as a rational creature, without
any other end or advantage to be attained thereby, in other words,
respect for a mere idea, should yet serve as an inflexible precept
of the will, and that it is precisely in this independence of the
maxim on all such springs of action that its sublimity consists; and
it is this that makes every rational subject worthy to be a
legislative member in the kingdom of ends: for otherwise he would
have to be conceived only as subject to the physical law of his
wants. And although we should suppose the kingdom of nature and the
kingdom of ends to be united under one sovereign, so that the latter
kingdom thereby ceased to be a mere idea and acquired true reality,
then it would no doubt gain the accession of a strong spring, but by
no means any increase of its intrinsic worth. For this sole absolute
lawgiver must, notwithstanding this, be always conceived as
estimating the worth of rational beings only by their disinterested
behaviour, as prescribed to themselves from that idea [the dignity
of man] alone. The essence of things is not altered by their
external relations, and that which abstracting from these, alone
constitutes the absolute worth of man, is also that by which he must
be judged, whoever the judge may be, and even by the Supreme Being.
MORALITY then is the relation of actions to the autonomy of the
will, that is, to the potential universal legislation by its maxims.
An action that is consistent with the autonomy of the will is
PERMITTED; one that does not agree therewith is FORBIDDEN. A will
whose maxims necessarily coincide with the laws of autonomy is a
HOLY will, good absolutely. The dependence of a will not absolutely
good on the principle of autonomy (moral necessitation) is
obligation. This then cannot be applied to a holy being. The
objective necessity of actions from obligation is called DUTY.

From what has just been said, it is easy to see how it happens that
although the conception of duty implies subjection to the law, we
yet ascribe a certain DIGNITY and sublimity to the person who
fulfills all his duties. There is not, indeed, any sublimity in him,
so far as he is subject to the moral law; but inasmuch as in regard
to that very law he is like-wise a legislator, and on that account
alone subject to it, he has sublimity. We have also shown above that
neither fear nor inclination, but simply respect for the law, is the
spring which can give actions a moral worth. Our own will, so far as
we suppose it to act only under the condition that its maxims are
potentially universal laws, this ideal will which is possible to us
is the proper object of respect, and the dignity of humanity
consists just in this capacity of being universally legislative,
though with the condition that it is itself subject to this same
legislation.

The Autonomy of the Will as the Supreme Principle of Morality

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

Heteronomy of the Will as the Source of all spurious Principles of
Morality

If the will seeks the law which is to determine it anywhere else
than in the fitness of its maxims to be universal laws of its own
dictation, consequently if it goes out of itself and seeks this law
in the character of any of its objects, there always results
HETERONOMY. The will in that case does not give itself the law, but
it is given by the object through its relation to the will. This
relation whether it rests on inclination or on conceptions of reason
only admits of hypothetical imperatives: I ought to do something
BECAUSE _I_ WISH FOR SOMETHING ELSE. On the contrary, the moral, and
therefore categorical, imperative says: I ought to do so and so,
even though I should not wish for anything else. Ex. gr. , the former
says: I ought not to lie if I would retain my reputation; the latter
says: I ought not to lie although it should not bring me the least
discredit. The latter therefore must so far abstract from all
objects that they shall have no INFLUENCE on the will, in order that
practical reason (will) may not be restricted to administering an
interest not belonging to it, but may simply show its own commanding
authority as the supreme legislation. Thus, ex. gr. , I ought to
endeavour to promote the happiness of others, not as if its
realization involved any concern of mine (whether by immediate
inclination or by any satisfaction indirectly gained through
reason), but simply because a maxim which excludes it cannot be
comprehended as a universal law [Footnote: I read allgemeines
instead of allgemeinem. ] in one and the same volition.

Classification of all Principles of Morality which can be founded on
the Conception of Heteronomy.

Here as elsewhere human reason in its pure use, so long as it was
not critically examined, has first tried all possible wrong ways
before it succeeded in finding the one true way.

All principles which can be taken from this point of view are either
EMPIRICAL or RATIONAL. The FORMER, drawn from the principle of
HAPPINESS, are built on physical or moral feelings; the LATTER,
drawn from the principle of PERFECTION, are built either on the
rational conception of perfection as a possible effect, or on that
of an independent perfection (the will of God) as the determining
cause of our will.

EMPIRICAL PRINCIPLES are wholly incapable of serving as a foundation
for moral laws. For the universality with which these should hold
for all rational beings without distinction, the unconditional
practical necessity which is thereby imposed on them, is lost when
their foundation is taken from the PARTICULAR CONSTITUTION OF HUMAN
NATURE, or the accidental circumstances in which it is placed. The
principle of PRIVATE HAPPINESS, however, is the most objectionable,
not merely because it is false, and experience contradicts the
supposition that prosperity is always proportioned to good conduct,
nor yet merely because it contributes nothing to the establishment
of morality--since it is quite a different thing to make a
prosperous man and a good man, or to make one prudent and sharp-
sighted for his own interests, and to make him virtuous--but because
the springs it provides for morality are such as rather undermine it
and destroy its sublimity, since they put the motives to virtue and
to vice in the same class, and only teach us to make a better
calculation, the specific difference between virtue and vice being
entirely extinguished. On the other hand, as to moral feeling, this
supposed special sense [Footnote: I class the principle of moral
feeling under that of happiness, because every empirical interest
promises to contribute to our well-being by the agreeableness that a
thing affords, whether it be immediately and without a view to
profit, or whether profit be regarded. We must likewise, with
Hutcheson, class the principle of sympathy with the happiness of
others under his assumed moral sense. ] the appeal to it is indeed
superficial when those who cannot THINK believe that FEELING will
help them out, even in what concerns general laws: and besides,
feelings which naturally differ infinitely in degree cannot furnish
a uniform standard of good and evil, nor has anyone a right to form
judgments for others by his own feelings: nevertheless this moral
feeling is nearer to morality and its dignity in this respect, that
it pays virtue the honour of ascribing to her IMMEDIATELY the
satisfaction and esteem we have for her, and does not, as it were,
tell her to her face that we are not attached to her by her beauty
but by profit.

Amongst the RATIONAL principles of morality, the ontological
conception of PERFECTION, notwithstanding its defects, is better
than the theological conception which derives morality from a Divine
absolutely perfect will. The former is, no doubt, empty and
indefinite, and consequently useless for finding in the boundless
field of possible reality the greatest amount suitable for us;
moreover, in attempting to distinguish specifically the reality of
which we are now speaking from every other, it inevitably tends to
turn in a circle, and cannot avoid tacitly presupposing the morality
which it is to explain; it is nevertheless preferable to the
theological view, first, because we have no intuition of the Divine
perfection, and can only deduce it from our own conceptions, the
most important of which is that of morality, and our explanation
would thus be involved in a gross circle; and, in the next place, if
we avoid this, the only notion of the Divine will remaining to us is
a conception made up of the attributes of desire of glory and
dominion, combined with the awful conceptions of might and
vengeance, and any system of morals erected on this foundation would
be directly opposed to morality.

However, if I had to choose between the notion of the moral sense
and that of perfection in general (two systems which at least do not
weaken morality, although they are totally incapable of serving as
its foundation), then I should decide for the latter, because it at
least withdraws the decision of the question from the sensibility
and brings it to the court of pure reason; and although even here it
decides nothing, it at all events preserves the indefinite idea (of
a will good in itself) free from corruption, until it shall be more
precisely defined.

For the rest I think I may be excused here from a detailed
refutation of all these doctrines; that would only be superfluous
labour, since it is so easy, and is probably so well seen even by
those whose office requires them to decide for one of these theories
(because their hearers would not tolerate suspension of judgment).
But what interests us more here is to know that the prime foundation
of morality laid down by all these principles is nothing but
heteronomy of the will, and for this reason they must necessarily
miss their aim.

In every case where an object of the will has to be supposed in
order that the rule may be prescribed which is to determine the
will, there the rule is simply heteronomy; the imperative is
conditional, namely, IF or BECAUSE one wishes for this object, one
should act so and so: hence it can never command morally, that is
categorically. Whether the object determines the will by means of
inclination, as in the principle of private happiness, or by means
of reason directed to objects of our possible volition generally, as
in the principle of perfection, in either case the will never
determines itself IMMEDIATELY by the conception of the action, but
only by the influence which the foreseen effect of the action has on
the will; _I_ OUGHT TO DO SOMETHING, ON THIS ACCOUNT, BECAUSE _I_
WISH FOR SOMETHING ELSE; and here there must be yet another law
assumed in me as its subject, by which I necessarily will this other
thing, and this law again requires an imperative to restrict this
maxim. For the influence which the conception of an object within
the reach of our faculties can exercise on the will of the subject
in consequence of its natural properties, depends on the nature of
the subject, either the sensibility (inclination and taste), or the
understanding and reason, the employment of which is by the peculiar
constitution of their nature attended with satisfaction. It follows
that the law would be, properly speaking, given by nature, and as
such, it must be known and proved by experience, and would
consequently be contingent, and therefore incapable of being an
apodictic practical rule, such as the moral rule must be. Not only
so, but it is INEVITABLY ONLY HETERONOMY; the will does not give
itself the law, but it is given by a foreign impulse by means of a
particular natural constitution of the subject adapted to receive
it. An absolutely good will, then, the principle of which must be a
categorical imperative, will be indeterminate as regards all
objects, and will contain merely the FORM OF VOLITION generally, and
that as autonomy, that is to say, the capability of the maxims of
every good will to make themselves a universal law, is itself the
only law which the will of every rational being imposes on itself,
without needing to assume any spring or interest as a foundation.

HOW SUCH A SYNTHETICAL PRACTICAL a priori PROPOSITION IS POSSIBLE
and why it is necessary, is a problem whose solution does not lie
within the bounds of the metaphysic of morals; and we have not here
affirmed its truth, much less professed to have a proof of it in our
power.
We simply showed by the development of the universally
received notion of morality that an autonomy of the will is
inevitably connected with it, or rather is its foundation. Whoever
then holds morality to be anything real, and not a chimerical idea
without any truth, must likewise admit the principle of it that is
here assigned. This section then, like the first, was merely
analytical. Now to prove that morality is no creation of the brain,
which it cannot be if the categorical imperative and with it the
autonomy of the will is true, and as an a priori principle
absolutely necessary, this supposes the POSSIBILITY OF A SYNTHETIC
USE OF PURE PRACTICAL REASON, which however we cannot venture on
without first giving a critical examination of this faculty of
reason. In the concluding section we shall give the principle
outlines of this critical examination as far as is sufficient for
our purpose.




THIRD SECTION

TRANSITION FROM THE METAPHYSIC OF MORALS TO THE CRITIQUE OF PURE
PRACTICAL REASOH


The Concept of Freedom is the Key that explains the Autonomy of the
Will

The WILL is a kind of causality belonging to living beings in so far
as they are rational, and FREEDOM would be this property of such
causality that it can be efficient, independently on foreign causes
DETERMINING it; just as PHYSICAL NECESSITY is the property that the
causality of all irrational beings has of being determined to
activity by the influence of foreign causes.

The preceding definition of freedom is NEGATIVE, and therefore
unfruitful for the discovery of its essence; but it leads to a
POSITIVE conception which is so much the more full and fruitful
Since the conception of causality involves that of laws, according
to which, by something that we call cause, something else, namely,
the effect, must be produced [laid down]; [Footnote: (Gesetzt. -There
is in the original a play on the etymology of Gesetz, which does not
admit of reproduction in English. It must be confessed that without
it the statement is not self-evident. )] hence, although freedom is
not a property of the will depending on physical laws, yet it is not
for that reason lawless; on the contrary it must be a causality
acting according to immutable laws, but of a peculiar kind;
otherwise a free will would be an absurdity. Physical necessity is a
heteronomy of the efficient causes, for every effect is possible
only according to this law, that something else determines the
efficient cause to exert its causality. What else then can freedom
of the will be but autonomy, that is the property of the will to be
a law to itself? But the proposition: The will is in every action a
law to itself, only expresses the principle, to act on no other
maxim than that which can also have as an object itself as a
universal law. Now this is precisely the formula of the categorical
imperative and is the principle of morality, so that a free will and
a will subject to moral laws are one and the same.

On the hypothesis then of freedom of the will, morality together
with its principle follows from it by mere analysis of the
conception. However the latter is still a synthetic proposition;
viz. , an absolutely good will is that whose maxim can always include
itself regarded as a universal law; for this property of its maxim
can never be discovered by analysing the conception of an absolutely
good will. Now such synthetic propositions are only possible in this
way: that the two cognitions are connected together by their union
with a third in which they are both to be found. The POSITIVE
concept of freedom furnishes this third cognition, which cannot, as
with physical causes, be the nature of the sensible world (in the
concept of which we find conjoined the concept of something in
relation as cause to SOMETHING ELSE as effect). We cannot now at
once show what this third is to which freedom points us, and of
which we have an idea a priori, nor can we make intelligible how the
concept of freedom is shown to be legitimate from principles of pure
practical reason, and with it the possibility of a categorical
imperative; but some further preparation is required.

Freedom must be presupposed as a Property of the Will of all
Rational Beings

It is not enough to predicate freedom of our own will, from whatever
reason, if we have not sufficient grounds for predicating the same
of all rational beings. For as morality serves as a law for us only
because we are RATIONAL BEINGS, it must also hold for all rational
beings; and as it must be deduced simply from the property of
freedom, it must be shown that freedom also is a property of all
rational beings. It is not enough then to prove it from certain
supposed experiences of human nature (which indeed is quite
impossible, and it can only be shown a priori), but we must show
that it belongs to the activity of all rational beings endowed with
a will. Now I say every being that cannot act except UNDER THE IDEA
OF FREEDOM is just for that reason in a practical point of view
really free, that is to say, all laws which are inseparably
connected with freedom have the same force for him as if his will
had been shown to be free in itself by a proof theoretically
conclusive. [Footnote: I adopt this method of assuming freedom
merely AS AN IDEA which rational beings suppose in their actions, in
order to avoid the necessity of proving it in its theoretical aspect
also. The former is sufficient for my purpose; for even though the
speculative proof should not be made out, yet a being that cannot
act except with the idea of freedom is bound by the same laws that
would oblige a being who was actually free. Thus we can escape here
from the onus which presses on the theory. (Compare Butler's
treatment of the question of liberty in his "Analogy," part I. , ch.
vi. )] Now I affirm that we must attribute to every rational being
which has a will that it has also the idea of freedom and acts
entirely under this idea. For in such a being we conceive a reason
that is practical, that is, has causality in reference to its
objects. Now we cannot possibly conceive a reason consciously
receiving a bias from any other quarter with respect to its
judgments, for then the subject would ascribe the determination of
its judgment not to its own reason, but to an impulse. It must
regard itself as the author of its principles independent on foreign
influences. Consequently as practical reason or as the will of a
rational being it must regard itself as free, that is to say, the
will of such a being cannot be a will of its own except under the
idea of freedom. This idea must therefore in a practical point of
view be ascribed to every rational being.

Of the Interest attaching to the Ideas of Morality

We have finally reduced the definite conception of morality to the
idea of freedom. This latter, however, we could not prove to be
actually a property of ourselves or of human nature; only we saw
that it must be presupposed if we would conceive a being as rational
and conscious of its causality in respect of its actions, i. e. , as
endowed with a will; and so we find that on just the same grounds we
must ascribe to every being endowed with reason and will this
attribute of determining itself to action under the idea of its
freedom.

Now it resulted also from the presupposition of this idea that we
became aware of a law that the subjective principles of action,
i. e. , maxims, must always be so assumed that they can also hold as
objective, that is, universal principles, and so serve as universal
laws of our own dictation. But why then should I subject myself to
this principle and that simply as a rational being, thus also
subjecting to it all other beings endowed with reason? I will allow
that no interest urges me to this, for that would not give a
categorical imperative, but I must take an interest in it and
discern how this comes to pass; for this "I ought" is properly an "I
would," valid for every rational being, provided only that reason
determined his actions without any hindrance. But for beings that
are in addition affected as we are by springs of a different kind,
namely, sensibility, and in whose case that is not always done which
reason alone would do, for these that necessity is expressed only as
an "ought," and the subjective necessity is different from the
objective.

It seems then as if the moral law, that is, the principle of
autonomy of the will, were properly speaking only presupposed in the
idea of freedom, and as if we could not prove its reality and
objective necessity independently. In that case we should still have
gained something considerable by at least determining the true
principle more exactly than had previously been done; but as regards
its validity and the practical necessity of subjecting oneself to
it, we should not have advanced a step. For if we were asked why the
universal validity of our maxim as a law must be the condition
restricting our actions, and on what we ground the worth which we
assign to this manner of acting--a worth so great that there cannot
be any higher interest; and if we were asked further how it happens
that it is by this alone a man believes he feels his own personal
worth, in comparison with which that of an agreeable or disagreeable
condition is to be regarded as nothing, to these questions we could
give no satisfactory answer.

We find indeed sometimes that we can take an interest [Footnote:
"Interest" means a spring of the will, in so far as this spring is
presented by Reason. See note, p. 391. ] in a personal quality which
does not involve any interest of external condition, provided this
quality makes us capable of participating in the condition in case
reason were to effect the allotment; that is to say, the mere being
worthy of happiness can interest of itself even without the motive
of participating in this happiness. This judgment, however, is in
fact only the effect of the importance of the moral law which we
before presupposed (when by the idea of freedom we detach ourselves
from every empirical interest); but that we ought to detach
ourselves from these interests, i. e. , to consider ourselves as free
in action and yet as subject to certain laws, so as to find a worth
simply in our own person whiph can compensate us for the loss of
everything that give worth to our condition; this we are not yet
able to discern in this way, nor do we see how it is possible so to
act--in other words, whence the moral law derives its obligation.

It must be freely admitted that there is a sort of circle here from
which it seems impossible to escape. In the order of efficient
causes we assume ourselves free, in order that in the order of ends
we may conceive ourselves as subject to moral laws: and we
afterwards conceive ourselves as subject to these laws, bjecause we
have attributed to ourselves freedom of will: for freedom and self-
legislation of will are both autonomy, and therefore are reciprocal
conceptions, and for this very reason one must not be used to
explain the other or give the reason of it, but at most only for
logical purposes to reduce apparently different notions of the same
object to one single concept (as we reduce different fractions of
the same value to the lowest terms).

One resource retrains to us, namely, to inquire whether we do not
occupy different points of view when by means of freedom we think
ourselves as causes efficient a priori, and when we form our
conception of ourselves from our actions as effects which we see
before our eyes.

It is a remark which needs no subtle reflection to make, but which
we may assume that even the commonest understanding can make,
although it be after its fashion by an obscure discernment of
judgment which it calls feeling, that all the "ideas" [Footnote: The
common understanding being here spoken of, I use the word "idea" in
its popular sense. ] that comes to us involuntarily (as those of the
senses) do not enable us to know objects otherwise than as they
affect us; so that what they may be in themselves remains unknown to
us, and consequently that as regards "ideas" of this kind even with
the closest attention and clearness that the understanding can apply
to them, we can by them only attain to the knowledge of appearances,
never to that of things in themselves. As soon as this distinction
has once been made (perhaps merely in consequence of the difference
observed between the ideas given us from without, and in which we
are passive, and those that we produce simply from ourselves, and in
which we show our own activity), then it follows of itself that we
must admit and assume behind the appearance something else that is
not an appearance, namely, the things in themselves; although we
must admit that as they can never be known to us except as they
affect us, we can come no nearer to them, nor can we ever know what
they are in themselves. This must furnish a distinction, however
crude, between a world of sense and the world of understanding, of
which the former may be different according to the difference of the
sensuous impressions in--various observers, while the second which
is its basis always remains the same. Even as to himself, a man
cannot pretend to know what he is in himself from the knowledge he
has by internal sensation. For as he does not as it were create
himself, and does not come by the conception of himself a priori but
empirically, it naturally follows that he can obtain his knowledge
even of himself only by the inner sense, and consequently only
through the appearances of his nature and the way in which his
consciousness is affected. At the same time beyond these
characteristics of his own subject, made up of mere appearances, he
must necessarily suppose something else as their basis, namely, his
ego, whatever its characteristics in itself may be. Thus in respect
to mere perception and receptivity of sensations he must reckon
himself as belonging to the world of sense, but in respect of
whatever there may be of pure activity in him (that which reaches
consciousness immediately and not through affecting the senses) he
must reckon himself as belonging to the intellectual world, of
which, however, he has no further knowledge. To such a conclusion
the reflecting man must come with respect ito all the things which
can be presented to him: it is probably to be met with even in
persons of the commonest understanding, who, as is well known, are
very much inclined to suppose behind the objects of the senses
something else invisible and acting of itself. They spoil it,
however, by presently sensualizing this invisible again; that is to
say, wanting to make it an object of intuition, so that they do not
become a whit the wiser.

Now man really finds in himself a faculty by which he distinguishes
himself from everything else, even from himself as affected by
objects, and that is Reason. This being pure spontaneity is even
elevated above the understanding. For although the latter is a
spontaneity and does not, like sense, merely contain intuitions that
arise when we are affected by things (and are therefore passive),
yet it cannot produce from its activity any other conceptions than
those which merely serve to bring the intuitions of sense under
rulesf and thereby to unite them in one consciousness, and without
this use of the sensibility it could not think at all; whereas, on
the contrary, Reason shows so pure a spontaneity in the case of what
I call Ideas [Ideal Conceptions] that it thereby far transcends
everything that the sensibility can give it, and exhibits its most
important function in distinguishing the world of sense from that of
understanding, and thereby prescribing the limits of the
understanding itself.

For this reason a rational being must regard himself qua
intelligence (not from the side of his lower faculties) as belonging
not to the world of sense, but to that of understanding; hence he
has two points of view from which he can regard himself, and
recognise laws of the exercise of his faculties, and consequently of
all his actions: first, so far as he belongs to the world of sense,
he finds himself subject to laws of nature (heteronomy); secondly,
as belonging to the intelligible world, under laws which being
independent on nature have their foundation not in experience but in
reason alone.

As a rational being, and consequently belonging to the intelligible
world, man can never conceive the causality of his own will
otherwise than on condition of the idea of freedom. for independence
on the determining causes of the sensible world (an independence
which Reason must always ascribe to itself) is freedom. Now the idea
of freedom is inseparably connected with the conception of autonomy,
and this again with the universal principle of morality which is
ideally the foundation of all actions of rational beings, just as
the law of nature is of all phenomena.

Now the suspicion is removed which we raised above, that there was a
latent circle involved in our reasoning from freedom to autonomy,
and from this to the moral law, viz. : that we laid down the idea of
freedom because of the moral law only that we might afterwards in
turn infer the latter from freedom and that consequently we could
assign no reason at all for this law, but could only [present]
[Footnote: The verb is wanting in the original. ] it as a petitio
principii which well disposed minds would gladly concede to us, but
which we could never put forward as a provable proposition. For now
we see that when we conceive ourselves as free we transfer ourselves
into the--world of understanding as members of it, and recognise the
autonomy of the will with its consequence, morality; whereas, if we
conceive ourselves as under obligation we consider ourselves as
belonging to the world of sense, and at the same time to the world
of understanding.

How is a Categorical Imperative Possible?

Every rational being reckons himself qua intelligence as belonging
to the world of understanding, and it is simply as an efficient
cause belonging to that world that he calls his causality a will. On
the other side he is also conscious of himself as a part of the
world of sense in which his actions which are mere appearances
[phenomena] of that causality are displayed; we cannot, however,
discern how they are possible from this causality which we do not
know; but instead of that, these actions as belonging to the
sensible world must be viewed as determined by other phenomena,
namely,--desires and inclinations. If therefore I were only a member
of the world of understanding, then all my actions would perfectly
conform to the principle of autonomy of the pure will; if I were
only a part of the world of sense they would necessarily be assumed
to conform wholly to the natural law of desires and inclinations, in
other words, to the heteronomy of nature. (The former would rest on
morality as the supreme principle, the latter on happiness. ), Since,
however, the world of understanding contains the foundation of the
world of sense, and consequently of its laws alsof and accordingly
gives the law to my will (which belongs wholly to the world of
understanding) directly, and must be conceived as doing so, it
follows that, although on the one side I must regard myself as a
being belonging to the world of sense, yet on the other side I must
recognise myself as subject as an intelligence to the law of the
world of understanding, i. e. , to reason, which contains this law in
the idea of freedom, and therefore as subject to the autonomy of the
will: consequently I must regard the laws of the world of
understanding as imperatives for me, and the actions which conform
to them as duties.

And thus what makes categorical imperatives possible is this, that
the idea of freedom makes me a member of an intelligible world, in
consequence of which if I were nothing else all my actions would
always conform to the autonomy of the will; but as I at the same
time intuite myself as a member of the world of sense, they ought so
to conform, and this categorical "ought" implies a synthetic a
priori proposition, inasmuch as besides my will as affected by
sensible desires there is added further the idea of the same will
but as belonging to the world of the understanding, pure and
practical of itself, which contains the supreme condition according
to Reason of the former will; precisely as to the intuitions of
sense there are added concepts of the understanding which of
themselves signify nothing but regular form in general, and in this
way synthetic a priori propositions become possible, on which all
knowledge of physical nature rests.

The practical use of common human reason confirms this reasoning.
There is no one, not even the most consummate villain, provided only
that he is otherwise accustomed to the use of reason, who, when we
set before him examples of tionesty of purposea of steadfastness in
following good maxims, of sympathy and general benevolence (even
combined with great sacrifices of advantages and comfort), does not
wish that he might also possess these qualities. Only on account of
his inclinations and impulses he cannot attain this in himself, but
at the same time he wishes to be free from such inclinations which
are burdensome to himself. He proves by this that he transfers
himself in thought with a will free from the impulses of--the
sensibility into an order of things wholly different from that of
his desires in the field of the sensibility; since he cannot expect
to obtain by that wish any gratification of his desires, nor any
position which would satisfy any of his actual or supposable
inclinations (for this would destroy the pre-eminence of the very
idea which wrests that wish from him): he can only expect a greater
intrinsic worth of his own person. This better person, however, he
imagines himself to be when he transfers himself to the point of
view of a member of the world of the understanding, to which he is
involuntarily forced by the idea of freedom, i. e. , of independence
on determining causes of the world of sense; and from this point of
view he is conscious of a good will, which by his own confession
constitutes the law for the bad will that he possesses as a member
of the world of sense-a law whose authority he recognises while
transgressing it. What he morally "ought" is then what he
necessarily "would" as a member of the world of the understanding,
and is conceived by him as an "ought" only inasmuch as he likewise
considers himself as a member of the world of sense.

On the Extreme Limits of all Practical Philosophy

All men attribute to themselves freedom of will. Hence come all
judgments upon actions as being such as ought to have been done,
although they have not been done. However, this freedom is not a
conception of experience, nor can it be so, since it still remains,
even though experience shows the contrary of what on supposition of
freedom are conceived as its necessary consequences. On the other
side it is equally necessary that everything that takes place should
be fixedly determined according to laws of nature. This necessity of
nature is likewise tot an empirical conception, just for this
reason, that it involves the motion of necessity and consequently of
a priori cognition. But this conception of a system of nature is
confirmed by experience, and it must even be inevitably presupposed
if experience itself is to be possible, that is, a connected
knowledge of the objects of sense resting on general laws. Therefore
freedom is only an Idea [Ideal Conception] of Reason, and its
objective reality in itself is doubtful, while nature is a concept
of the understanding which proves, and must necessarily prove, its
reality in examples of experience.

There arises from this a dialectic of Reason, since the freedom
attributed to the will appears to contradict the necessity of
nature, and placed between these two ways Reason for speculative
purposes finds the road of physical necessity much more beaten and
more appropriate than that of freedom; yet for practical purposes
the narrow footpath of freedom is the only one on which it is
possible to make use of reason in our conduct; hence it is just as
impossible for the subtlest philosophy as for the commonest reason
of men to argue away freedom. Philosophy must then assume that no
real contradiction will be found between freedom and physical
necessity of the same human actions, for it cannot give up the
conception of nature any more than that of freedom.

Nevertheless, even though we should never be able to comprehend how
freedom is possible, we must at least remove this apparent
contradiction in a convincing manner. For if the thought of freedom
contradicts either itself or nature, which is equally necessary, it
must in competition with physical necessity be entirely given up.

It would, however, be impossible to escape this contradiction if the
thinking subject, which seems to itself free, conceived itself in
the same sense or in the very same relation when it calls itself
free as when in respect of the same action it assumes itself to be
subject to the law of nature. Hence it is an indispensable problem
of speculative philosophy to show that its illusion respecting the
contradiction rests on this, that we think of man in a different
sense and relation when we call him free, and when we regard him as
subject to the laws of nature as being part and parcel of nature. It
must, therefore, show that not only can both these very well co-
exist, but that both must be thought as necessarily united in the
same subject, since otherwise no reason could be given why we should
burden reason with an idea which, though it may possibly without
contradiction be reconciled with another that is sufficiently
established, yet entangles us in a perplexity which sorely
embarrasses Reason in its theoretic employment. This duty, however,
belongs only to speculative philosophy, in order that it may clear
the way for practical philosophy. The philosopher then has no option
whether he will remove the apparent contradiction or leave it
untouched; for in fhe latter case the theory respecting this would
be bonum vacans into the possession of which the fatalist would have
a right to enter, and chase all morality out of its supposed domain
as occupying it without title.

We cannot, however, as yet say that we are touching the bounds of
practical philosophy. For the settlement of that controversy does
not belong to it; it only demands from speculative reason $hat it
should put an end to the discord in which it entangles itself in
theoretical questions, so that practical reason may have rest and
security from external attacks which might make the ground debatable
on which it desires to build.

The claims to freedom of will made even by common reason are founded
on the consciousness and the admitted supposition that reason is
independent on merely subjectively determined causes which together
Constitute what belongs to sensation only, and which consequently
come under the general designation of sensibility. Man considering
himself in this way as an intelligence, places himself thereby in a
different order of things and in a relation to determining grounds
of a wholly different kind when on the one hand he thinks of himself
as an intelligence endowed with a will, and consequently with
causality, and when on the other he perceives himself as a
phenomenon in the world of sense (as he really is also), and affirms
that his causality is subject to external determination according to
laws of nature. [Footnote: The punctuation of the original gives the
following sense: "Submits his causality, as regards its external
determination, to laws of nature. " have ventured to make what
appears to be a necessary correction, by simply removing a comma. ]
Now he soon becomes aware that both can hold good, nay, must hold
good at the same time. For there is not the smallest contradiction
in saying that a thing in appearance (belonging to the world of
sense) is subject to certain laws, on which the very same as a thing
or being in itself is independent; and that he must conceive and
think of himself in this twofold way, rests as to the first on the
consciousness of himself as an object affected through the senses,
and as to the second on the consciousness of himself as an
intelligence, i. e. , as independent on sensible impressions in the
employment of his reason (in other words as belonging to the world
of understanding).

Hence it comes to pass that man claims the possession of a will
which takes no account of anything that comes under the head of
desires and inclinations, and on the contrary conceives actions as
possible to him, nay, even as necessary, which can only be done by
disregarding all desires and sensible inclinations. The causality of
such actions [Footnote: M. Barni translates as if he read desselben
instead of derselben, "the causality of this will. " So also Mr.
Semple. ] lies in him as an intelligence and in the laws of effects
and actions [which depend] on the principles of an intelligible
world, of which indeed he knows nothing more than that in it pure
reason alone independent on sensibility gives the law; moreover
since it is only in that world, as an intelligence, that he is his
proper self (being as man only the appearance of himself) those laws
apply to him directly and categorically, so that the incitements of
inclinations and appetites (in other words the whole nature of the
world of sense) cannot impair the laws of his volition as an
intelligence. Nay, he does not even hold himself responsible for the
former or ascribe them to his proper self, i. e. , his will: he only
ascribes to his will any indulgence which he might yield them if he
allowed them to influence his maxims to the prejudice of the
rational laws of the will.

When practical Reason thinks itself into a world of understanding it
does not thereby transcend its own limits, as it would if it tried
to enter it by intuition or sensation. The former is only a negative
thought in respect of the world of sense, which does not give any
laws to reason in determining the will, and is positive only in this
single point that this freedom as a negative characteristic is at
the same time conjoined with a (positive) faculty and even with a
causality of reason, which we designate a will, namely, a faculty of
so acting that the principle of the actions shall conform to the
essential character of a rational motive, i. e. , the condition that
the maxim have universal validity as a law. But were it to borrow an
object of will, that is, a motive, from the world of understanding,
then it would overstep its bounds and pretend to be acquainted with
something of which it knows nothing. The conception of a world of
the understanding is then only a point of view which Reason finds
itself compelled to take outside the appearances in order to
conceive itself as practical, which would not be possible if the
influences of the sensibility had a determining power on man, but
which is necessary unless he is to be denied the consciousness of
himself as an intelligence, and consequently as a rational cause,
energizing by reason, that is, operating freely. This thought
certainly involves the idea of an order and a system of laws
different from that of the mechanism of nature which belongs to the
sensible world, and it makes the conception of an intelligible world
necessary (that is to say, the whole system of rational beings as
things in themselves). But it does not in the least authorize us to
think of it further than as to its formal condition only, that is,
the universality of the maxims of the will as laws, and consequently
the autonomy of the latter, which alone is consistent with its
freedom; whereas, on the contrary, all laws that refer to a definite
object give heteronomy, which only belongs to laws of nature, and
can only apply to the sensible world.

But Reason would overstep all its bounds if it undertook to explain
how pure reason can be practical, which would be exactly the same
problem as to explain how freedom is possible.

For we can explain nothing but that which we can reduce to laws, the
object of which can be given in some possible experience. But
freedom is a mere Idea [Ideal Conception], the objective reality of
which can in no wise be shown according to laws of nature, and
consequently not in any possible experience; and for this reason it
can never be comprehended or understood, because we cannot support
it by any sort of example or analogy. It holds good only as a
necessary hypothesis of reason in a being that believes itself
conscious of a will, that is, of a faculty distinct from mere desire
(namely, a faculty of determining itself to action as an
intelligence), in other words, by laws of reason independently on
natural instincts. Now where determination according to laws of
nature ceases, there all explanation ceases also, and nothing
remains but defence, i. e. the removal of the objections of those
who pretend to have seen deeper into the nature of things, and
thereupon boldly declare freedom impossible. We can only point out
to them that the supposed contradiction that they have discovered in
it arises only from this, that in order to be able to apply the law
of nature to human actions, they must necessarily consider man as an
appearance: then when we demand of them that they should also think
of him qua intelligence as a thing in itself, they still persist in
considering him in this respect also as an appearance. In this view
it would no doubt be a contradiction to suppose the causality of the
same subject (that is, his will) to be withdrawn from all the
natural laws of the sensible world. But this contradiction
disappears, if they would only bethink themselves and admit, as is
reasonable, that behind the appearances there must also lie at their
root (although hidden) the things in themselves, and that we cannot
expect the laws of these to be the same as those that govern their
appearances.

The subjective impossibility of explaining the freedom of the will
is identical with the impossibility of discovering and explaining an
interest [Footnote: Interest is that by which reason becomes
practical, i. e. , a cause determining the will. Hence we say of
rational beings only that they take an interest in a thing;
irrational beings only feel sensual appetites. Reason takes a direct
interest in action then only when the universal validity of its
maxims is alone sufficient to determine the will. Such an interest
alone is pure. But if it can determine the will only by means of
another object of desire or on the suggestion of a particular
feeling of the subject, then Reason takes only an indirect interest
in the action, and as Reason by itself without experience cannot
discover either objects of the will or a Special feeling actuating
it, this latter interest would only be empirical, and not a pure
rational interest. The logical interest of Reason (namely, to extend
its insight) is never direct, but presupposes purposes for which
reason is employed. ] which man can take in the moral law.
Nevertheless he does actually take an interest in it, the basis of
which in us we call the moral feeling, which some have falsely
assigned as the standard of our moral judgment, whereas it must
rather be viewed as the subjective effect that the law exercises on
the will, the objective principle of which is furnished by Reason
alone.

In order indeed that a rational being who is also affected through
the senses should will what Reason alone directs such beings that
they ought to will, it is no doubt requisite that reason should have
a power to infuse a feeling of pleasure or satisfaction in the
fulfilment of duty, that is to say, that it should have a causality
by which it determines the sensibility according to its own
principles. But it is quite impossible to discern, i. e. , to make it
intelligible a priori, how a mere thought, which itself contains
nothing sensible, can itself produce a sensation of pleasure or
pain; for this is a particular kind of causality of which as of
every other causality we can determine nothing whatever a priori, we
must only consult experience about it. But as this cannot supply us
with any relation of cause and effect except between two objects of
experience, whereas in this case, although indeed the effect
produced lies within experience, yet the cause is supposed to be
pure reason acting through mere ideas which offer no object to
experience, it follows that for us men it is quite impossible to
explain how and why the universality of the maxim as a law, that is,
morality, interests. This only is certain, that it is not because it
interests us that it has validity for us (for that would be
heteronomy and dependence of practical reason on sensibility,
namely, on a feeling as its principle, in which case it could never
give moral laws), but that it interests us because it is valid for
us as men, inasmuch as it had its source in our will as
intelligences, in other words in our proper self, and what belongs
to mere appearance is necessarily subordinated by reason to the
nature of the thing in itself.

The question then: How a categorical imperative is possible can be
answered to this extent that we can assign the only hypothesis on
which it is possible, namely, the idea of freedom; and we can also
discern the necessity of this hypothesis, and this is sufficient for
the practical exercise of reason, that is, for the conviction of the
validity of this imperative, and hence of the moral law; but how
this hypothesis itself is possible can never be discerned by any
human reason. On the hypothesis, however, that the will of an
intelligence is free, its autonomy, as the essential formal
condition of its determination, is a necessary consequence.
Moreover, this freedom of will is not merely quite possible as a
hypothesis (not involving any contradiction to the principle of
physical necessity in the connexion of the phenomena of the sensible
world) as speculative philosophy can show: but further, a rational
being who is conscious of a causality [Footnote: Reading "einer" for
"seiner. "] through reason, that is to say, of a will (distinct from
desires), must of necessity make it practically, that is, in idea,
the condition of all his voluntary actions. But to explain how pure
reason can be of itself practical without the aid of any spring of
action that could be derived from any other source, i. e. how the
mere principle of the universal validity of all its maxims as laws
(which would certainly be the form of a pure practical reason) can
of itself supply a spring, without any matter (object) of the will
in which one could antecedently take any interest; and how it can
produce an interest which would be called purely moral; or in other
words, how pure reason can be practical--to explain this is beyond
the power of human reason, and all the labour and pains of seeking
an explanation of it are lost.

It is just the same as if I sought to find out how freedom itself is
possible as the causality of a will. For then I quit the ground of
philosophical explanation, and I have no other to go upon. I might
indeed revel in the world of intelligences which still remains to
me, but although I have an idea of it which is well founded, yet I
have not the least knowledge of it, nor can I ever attain to such
knowledge with all the efforts of my natural faculty of reason. It
signifies only a something that remains over when I have eliminated
everything belonging to the world of sense from the actuating
principles of my will, serving merely to keep in bounds the
principle of motives taken from the field of sensibility; fixing its
limits and showing that it does not contain all in all within
itself, but that there is more beyond it; but this something more I
know no further. Of pure reason which frames this ideal, there
remains after the abstraction of all matter, i. e. , knowledge of
objects, nothing but the form, namely, the practical law of the
universality of the maxims, and in conformity with this the
conception of reason in reference to a pure world of understanding
as a possible efficient cause, that is a cause determining the will.
There must here be a total absence of springs; unless this idea of
an intelligible world is itself the spring, or that in which reason
primarily takes an interest; but to make this intelligible is
precisely the problem that we cannot solve.

Here now is the extreme limit of all moral inquiry, and it is of
great importance to determine it even on this account, in order that
reason may not on the one hand, to the prejudice of morals, seek
about in the world of sense for the supreme motive and an interest
comprehensible but empirical; and on the other hand, that it may not
impotently flap its wings without being able to move in the (for it)
empty space of transcendent concepts which we call the intelligible
world, and so lose itself amidst chimeras. For the rest, the idea of
a pure world of understanding as a system of all intelligences, and
to which we ourselves as tational beings belong (although we are
likewise on the other side members of the sensible world), this
remains always a useful and legitimate idea for the purposes of
rational belief, although all knowledge stops at its threshold,
useful, namely, to produce in us a lively interest in the moral law
by means of the noble ideal of a universal kingdom of ends in
themselves (rational beings), to which we can belong as members then
only when we carefully conduct ourselves according to the maxims of
freedom as if they were laws of nature.

Concluding Remark

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




BYRON AND GOETHE

BY GIUSEPPE MAZZINI


INTRODUCTORY NOTE

Giuseppe Mazzini, the great political idealist of the Italian
struggle for independence, was born at Genoa, June 22, 1805. His
faith in democracy and his enthusiasm for a free Italy he inherited
from his parents; and while still a student in the University of
Genoa he gathered round him a circle of youths who shared his
dreams. At the age of twenty-two he joined the secret society of the
Carbonari, and was sent on a mission to Tuscany, where he was
entrapped and arrested. On his release, he set about the formation,
among the Italian exiles in Marseilles, of the Society of Young
Italy, which had for its aim the establishment of a free and united
Italian republic. His activities led to a decree for his banishment
from France, but he succeeded in outwitting the spies of the
Government and going on with his work. The conspiracy for a national
rising planned by Young Italy was discovered, many of the leaders
were executed, and Mazsini himself condemned to death.

Almost at once, however, he resumed operations, working this time
from Geneva; but another abortive expedition led to his expulsion
from Switzerland. He found refuge, but at first hardly a livelihood,
in London, where he continued his propaganda by means of his pen.
