Kant’s moral and political philosophy
Kant’s moral and political philosophy
Don Becker
Practical philosophy, for Kant, is concerned with how one ought to act.
His first important work in practical philosophy, Foundations of the
Metaphysics of Morals, provides Kant’s argument for the fundamental
principle of how one ought to act, called the “categorical imperative,”
which basically requires one to act only according to principles that are
themselves fit to be universal law. In Part I of this chapter we will focus on
Kant’s argument for the categorical imperative, and see how it functions as
the fundamental principle of his moral philosophy. In Part II we will look
at Kant’s political philosophy, seeing both that it is grounded in this
fundamental principle of how one ought to act, and that it gains support
from other aspects of Kant’s philosophical thinking.
PART I: KANT’S MORAL PHILOSOPHY
Inasmuch as Kant thinks that the fundamental principle of how one ought to
act must be capable of grounding a definitive answer in all circumstances, he
recognizes that no empirical study, which is dependent on the contingent
nature of the world as we experience it, can provide the sort of principle that
he seeks. Instead, Kant will proceed with an a priori study of how one ought
to act, which, insofar as it is independent of the contingent nature of the
world as we experience it, can provide a definitive principle. Two forms of a
priori study that Kant employs are the analysis of concepts and
transcendental arguments. According to the former, insofar as some concept
applies, whatever is entailed in that concept is true. According to the latter,
insofar as some concept applies, whatever is a necessary condition of its
application is true. Thus, Kant begins with the two concepts that are
fundamental to his intended study, “morality” and “rational being,” and
determines that they reveal the truth of the categorical imperative.
(Although the concept “rational being” is really the fundamental concept
employed by Kant, the concept “morality,” which he could have derived
from the concept “rational being,” plays a central role in his presentation.)
Kant’s presentation includes two basic steps. First, he asks what is meant by
the concept “morality,” and argues that it entails rational beings acting in
accord with the categorical imperative. This, however, only answers the
question of what morality is on the assumption that morality exists. Kant
then considers the concept “rational being,” and argues that a necessary
condition of a being thinking that this concept applies to itself is that it think
of itself as free. Furthermore, since Kant equates freedom in this sense (i.e.
“positive freedom”) with what he calls autonomy, and autonomy with
subjection to the categorical imperative, it follows that beings who think of
themselves as rational must consider themselves to be subject to the
categorical imperative that he has described.1
“Morality” and “rational beings”
Kant engages in the a priori study of ethics, or metaphysics of morals,
because this is the only way to gain definitive knowledge of how one
ought to act. He proceeds by first considering what is meant by
“morality,” and determining that it means neither more nor less than
acting according to the categorical imperative (FMM, 58).2 Although more
must be said before it is possible to explain the categorical imperative
fully, and the exact nature of the moral principle that it designates,
nevertheless, if one merely considers the two words that make up the term,
an important aspect of its nature is revealed. “Categorical” means
absolute, without qualification or exception, and “imperative” refers to a
type of command. Thus, a categorical imperative is an absolute command.
According to Kant, “Everyone must admit that a law, if it is to hold morally
(i.e. as a ground of obligation), must imply absolute necessity” (FMM, 5).
Thus, Kant treats it as obvious to everyone that morality ultimately entails an
absolute command or categorical imperative. Furthermore, since nothing
absolute can be derived from something contingent, he argues that the only
way to determine the exact nature of this absolute command is to engage in the
a priori study of practical reason (i.e. reason related to acting):
unless we wish to deny all truth to the concept of morality and
renounce its application to any possible object, we cannot refuse to
admit that the law is of such broad significance that it holds not
merely for men but for all rational beings as such; we must grant
that it must be valid with absolute necessity and not merely under
contingent conditions and with exceptions. For with what right
could we bring into unlimited respect something that might be valid
only under contingent human conditions? And how could laws of the
determination of our will be held to be laws of the determination of
the will of any rational being whatever and of ourselves in so far as
we are rational beings, if they were merely empirical and did not
have their origin completely a priori in pure, but practical reason?
(FMM, 24)
Kant holds that morality entails absolute laws; that, insofar as they are
absolute, these laws must hold not only for human beings but for all
similar, i.e. rational, beings; and that to have such general applicability
these laws cannot be learned through experience or any empirical study,
but must be derived through a purely a priori study.
Kant thinks that people, insofar as they are rational, are subject to an
absolute moral law. Kant thinks that the fact that rational beings are
subject to an absolute moral law is what fundamentally distinguishes them
from all of the other material things in the world, which he recognizes to
be subject to the laws of nature. Thus, Kant distinguishes physics, which is
concerned with those objects that are subject to the “laws of nature,”
from ethics, which is concerned with those objects that are subject to the
“laws of freedom” (FMM, 3). As will become clear, these laws of freedom
constitute the absolute moral law.
This distinction between physics and ethics can be somewhat confusing;
after all, isn’t everything subject to the laws of nature? Maybe not. Think
for a moment of a world in which everything were subject to the laws of
nature. This would be a world of strict causal determinism; everything
that happened would have followed inexorably from what preceded it.
Among other things, all human behavior would be completely determined
by these laws. But if all human behavior is causally determined according
to laws of nature, then in what sense could people be considered morally
responsible for their acts? Thus, if the concept “morality” is to make
sense, then it must be possible to think of people not only as common
physical entities subject to the laws of nature, but also, in another sense, as
rational beings, subject to the laws of freedom (see FMM, 68–73).
Kant thinks of people in just this dual way, as sensible or physical beings,
causally determined according to the laws of nature, and as intelligible or
purely rational beings, independent of causal determinism and capable of
acting in accord with the laws of freedom. Accordingly, Kant suggests that the
human will is subjected to two influences (see e.g. FMM, 16, 42). As sensible
or physical beings, human beings have desires that arise from their physical
nature and corresponding physical needs, which Kant broadly characterizes
as the desire to be happy. This universal desire, as well as other
indiosyncratic particular desires, is the source of inclinations, which exert a
potentially controlling influence on the will. However, insofar as human
beings are intelligible or purely rational beings, they recognize the laws of
freedom, resist the force of inclination, and determine their will for
themselves, independently of external influences and inclinations.
Furthermore, and recognition of this is crucial for a correct understanding of
Kant’s moral philosophy, Kant thinks that all rational beings, insofar as they
determine their will for themselves independently of their inclinations, will
recognize the very same principle, the categorical imperative, as expressing
the law of freedom in accord with which they ought to act (FMM, 71).
Thus far we have seen that the concept of “morality” entails the notion
of an absolute law or “categorical imperative,” and that it can only apply
to (rational) beings who can resist their inclinations and choose to follow
such a law of freedom. Let us now look more closely at exactly what Kant
means by a “categorical imperative.”
Kant’s concept of a categorical imperative
Imagine that the human will were influenced only by pure reason.
Whatever pure reason recognized as right would necessarily be willed, and
whoever was possessed of pure reason would never do wrong. But Kant
has said that the human will is influenced by both reason and inclination.
Therefore, human beings don’t necessarily will (and consequently act) as
pure reason reveals is right, because they can be led astray by their
inclinations. Thus, if a human will is to be determined in accordance with
the objective moral law, it must be constrained. Kant calls the formula
that expresses the command that constrains this will an imperative. Kant
holds that there are two types of imperatives:
All imperatives command either hypothetically or categorically. The
former present the practical necessity of a possible action as a means
to achieving something else which one desires (or which one may
possibly desire). The categorical imperative would be one which
presented an action as of itself objectively necessarily, without regard
to any other end.
(FMM, 30)
Two points that are rather important to Kant are expressed in this
passage.
First, Kant reveals the basic difference between hypothetical and
categorical imperatives. All imperatives determine the will to some good,
but hypothetical imperatives say only that some action is good given that
one has a particular purpose. Hypothetical imperatives reveal the means
to given ends. Since these ends are contingent, however, as are all the
ends that one commonly imagines (including the desire for happiness)
inasmuch as there is no necessity for human beings to be so constituted
that they have any of the particular desires that they experience, these
ends cannot give rise to a categorical imperative. A categorical
imperative, as Kant says, cannot depend on any contingent end, but
“would be one which presented an action as of itself objectively
necessary.”
Second, by saying of a categorical imperative that it “would be one…,’
Kant is making it clear that there may be no categorical imperative. Kant
is only talking about what a categorical imperative would be like if one
existed. This is very important, and is consistent with a point made earlier.
Human beings can only be subject to a moral law if they are capable of
resisting the influences of their inclinations, and determining their wills
through reason in accord with a principle or law that is known a priori.
There can be no moral responsibility for beings whose actions are all
causally determined. Thus, before Kant can actually assert that there is a
categorical imperative, he must first show that human beings have reason
to believe themselves capable of determining their wills through reason.
Nevertheless, Kant’s argumentative strategy is to hold off on the question
of whether human beings are actually subject to the categorical
imperative, and to first pursue the question of what a categorical
imperative would be, assuming that one exists.
The first formulation of the categorical imperative
Kant argues that there can be only one categorical imperative, and that,
from the very idea of a categorical imperative, one can deduce a formula
of the categorical imperative. Kant’s argument can be expressed as follows
(see FMM, 37–8). A categorical imperative is an absolute law. Although it
is obvious that a categorical imperative entails an absolute law, it is not at
all clear what this law will command. Imagine any possible content of this
law, say, to maximize human happiness. Insofar as what constitutes
human happiness is contingent (human beings could be constituted
differently), all that one can construct is a hypothetical imperative directed
to a particular contingent end. Thus, a categorical imperative cannot be
directed to any particular contingent end.
But if the imperative cannot be directed toward any particular
contingent ends, then what is left? Although later a formulation of the
categorical imperative that is based on an end that is not contingent will
be considered, for now it seems that the imperative can require nothing
more than conformity to absolute law. But since there is nothing in
particular to which this absolute law can be directed, it can command only
that one act in a way that is at least consistent with the possibility of
absolute law. Kant expresses this categorical imperative as follows: “Act
only according to that maxim by which you can at the same time will that
it should become a universal law” (FMM, 38). This imperative does not
rely on any specific content, but states the formal requirement that one
always act in a way that one could will to be required to act by an
absolute law.
The application of the categorical imperative and the distinction
between perfect and imperfect duties
What does it mean to act only according to that maxim by which you
can at the same time will that it should become a universal law? First,
what is a maxim? A maxim is a general principle according to which an
individual acts. Thus, one might hold the maxim “I will watch television
when bored,” or “I will steal things when I desire more goods.” Kant
is saying that it is morally permissible to act according to one’s maxim
only if it is possible at the same time to will that it should become a
universal law.
One of the most famous examples that Kant uses to help make his point
clear is that of the maxim to make a false promise to honor one’s debt
when seeking a loan that one does not intend to pay back (see e.g. FMM,
18–19, 39). Can one hold this maxim and, at the same time, will that it
should be a universal law? Well, imagine that there were a universal law to
make false promises. In such circumstances, inasmuch as no one could be
trusted, the institution of promising itself could not exist. Now, since it is
logically impossible for one at the same time to will both to make a false
promise and that the institution of promising not exist, it is immoral to act
on the maxim to make a false promise when desirous of another’s money.
Thus, the categorical imperative, as well as stating a restriction on
permissible behavior, also provides a test of whether the restriction
applies. If one cannot conceive of acting on the maxim while, at the same
time, the maxim holds as a universal law, as is the case in the example
of the false promise, then the maxim fails the test and may not be
acted upon.
Immediately after introducing the categorical imperative, Kant provides
four examples of its application, which are designed to represent a
common division of duties into four basic categories. Kant provides
examples of perfect duties and imperfect duties both to oneself and to
others, which can be classified as shown below.
Duty to oneself Duty to others
Perfect duty Do not commit suicide Do not falsely promise
Imperfect duty Develop talents Be beneficent
While the distinction between duties to oneself and duties to others
requires no explanation, this is not the case with the distinction between
perfect and imperfect duties. Kant was not the first to distinguish between
perfect and imperfect duties, but his distinction does not correspond
exactly with that of his predecessors (FMM, 38 n.). As Kant employs the
concepts, perfect duties are those with which one’s every action must
conform. Thus, in all but one special case (i.e. the duty to join the state),
perfect duties actually entail prohibitions against actions that should never
be performed under any circumstances, e.g. stealing and murder. Imperfect
duties, for Kant, entail principles that one must adopt, but that one need
not (and, in fact, cannot) act upon in every instance. One would not think
of another as moral who did not hold, and in some appropriate
circumstances act upon, the principle “Be beneficent.” However, it is also
clear that it is not possible for one’s every act to be the fulfillment of an
imperfect duty. For one thing, one’s every act cannot be, say, beneficent,
since one also must tend to one’s own physical needs. Even more
obviously, one’s every act cannot be one of beneficence, and also one of
developing talents, and also one that furthers every other imperfect duty.
Thus, Kant distinguishes between those duties with which one’s every act
must accord, and those duties that require one to adopt a principle, but
leave one leeway in deciding when to act upon it.
With this distinction between perfect and imperfect duties in mind, it is
important to look back to the categorical imperative, and to the test of the
permissibility of actions. There are two ways that a maxim can fail the test
of the categorical imperative. There are maxims for which it is logically
impossible, and thus inconceivable, for one to will the maxim and its
universalization at the same time, as in the false promise example
discussed above, and there are maxims for which there is merely a
contradiction in the will of an individual who wills both the maxim and its
universalization at the same time, as in the example discussed below. Kant
recognizes that there is an exact correspondence both between the duties
generated by maxims failing the test of the categorical imperative in the
former manner and perfect duties, and between the duties generated by
maxims failing the test of the categorical imperative in the latter manner
and imperfect duties (FMM, 40–1).3 Both Kant’s test of duties entailed in
the categorical imperative and his reformulation of the distinction between
perfect and imperfect duties gain support from this correspondence.
Having already seen in the example of a false promise how perfect duties
are related to maxims for which it is inconceivable to will both the maxim
and its universalization at the same time, let us turn to an example of an
imperfect duty. Consider the maxim “I will not develop my talents when I
seem to be doing fine without bothering.” There is no logical contradiction
that results from holding this maxim and, at the same time, willing that it
should become a universal law. After all, one can very well imagine a rather
easy life on a tropical island where one need do nothing more than pick fruit
when hungry. Thus, adopting this maxim does not violate a perfect duty.
Remember, however, that the categorical imperative says to “act only
according to that maxim by which you can at the same time will that it
should become a universal law.” While the test of perfect duties focuses on
whether one can will that the maxim should become a universal law,
thereby focusing on the logical possibility of holding the maxim and its
universalization at the same time, the test of imperfect duties focuses on the
question of whether one can will that the maxim should become a universal
law. It may be logically possible to live a human life without developing
one’s talents, and yet it may be impossible, without contradiction, to will to
live such a life. Although Kant’s treatment of the examples of imperfect
duties is very unclear, I think that one can make the best sense of his
discussion if one reads him as saying that the human will is essentially
unlimited in that it can hold anything imaginable as its object, and that a
contradiction therefore results if one wills to place a limitation on one’s own
will. Thus, it is not logically impossible for people to will not to develop
their talents (it doesn’t violate a perfect duty) but it entails a contradiction in
their will, since, on the one hand, their wills are essentially unlimited, but,
on the other hand, willing the nondevelopment of one’s talents yields a
limitation on what one can effectively will. According to this analysis, it
follows that there is an imperfect duty to develop one’s talents.
The second formulation of the categorical imperative
Although Kant thinks that there is only one categorical imperative, he
thinks that it can be formulated in more than one way. Of course, any
other formulation of the categorical imperative, if it is to be a formulation
of the same imperative, must require and prohibit exactly the same actions
as the first formulation. Although Kant maintains that the first
formulation discussed above is the most fundamental and precise, he
develops alternative formulations of the categorical imperative because
they make the demands of morality more intuitively plausible (FMM, 53).
The derivation of the first formulation of the categorical imperative can
be thought of as based on a consideration of the necessary form of a
categorical imperative. The idea is that the imperative must express an
absolute law, but, since the law cannot command any contingent particular
and still be absolute, all that can be commanded is that any particular
maxim to be acted upon must be of such a form that it could be universal
law. The second formulation of the categorical imperative, in contrast,
focuses on the proper content of one’s maxims (FMM, 48, 53). Kant bases
the second formulation of the categorical imperative on his view that
rational beings have absolute value as ends in themselves (FMM, 45–6).
Although Kant’s argument in support of this view of rational beings is
not very clear, it appears to rely on two fundamental claims. Kant has
elsewhere said that the only thing that is good without qualification is a
good will (since anything else can be put to a bad end, but not good
willing itself) (FMM, 9–10), and seems to allude to this position during the
argument. He also begins the discussion of which this argument is a part
by reminding his readers that only rational beings have a will (FMM, 44).
From these two claims it is reasonable to conclude that rational beings are
of absolute value because they are the only possible source of that which is
good without qualification. An imperative with content can therefore be a
categorical imperative, provided that the end of that imperative is for
rational beings to be treated as ends. Thus, the second formulation of the
categorical imperative is: “Act so that you treat humanity, whether in your
own person or in that of another, always as an end and never as a means
only”4 (FMM, 46). This imperative includes an absolute prohibition
against treating others as means only, and to do so would violate a perfect
duty. It also requires one actively to treat others as ends, and this
requirement is an imperfect duty. A reconsideration of the examples
introduced earlier will help make this clear.
Consider what happens when Mary makes a false promise to John, say
to pay back a loan when, in fact, she intends to flee to Brazil. Mary has
used John as a means for gaining the money she needs to go to Brazil. It is
true that virtually any time two people make an agreement they are
treating one another as means, but the important thing is that when the
agreement is honest they are not treating one another as a means only.
When making an honest agreement, people know more or less how they
are furthering the interests of another, and this furthering of the other’s
interests is an explicit part of their own act. Thus, in honest agreements
people treat one another as means, but they also respect one another as
ends, insofar as the other has been able to make a free and informed
decision as to whether to participate in the agreement. However, when
Mary exploited John’s trust by making a false promise, she treated him as
a means only, in that he was not given the relevant information with
which to decide whether he wanted to provide the benefit to Mary that
she actually received. He was not treated as an end at all, in that he was
not provided the opportunity to embrace the results of their interaction as
an end of his own. Thus, Mary violated a perfect duty by treating another
rational being, not as an end, but as a means only.
Now imagine that Mary is a botanist fascinated by, and extremely
talented at, studying tropical deforestation, and she asks John, who won
$50 million in the lottery, to help fund a research trip to Brazil. Here there
is no question of perfect duties. Neither Mary’s request for support, nor
John’s either providing it or refusing to do so, entails treating a rational
being as a means only. But should John provide the support? Were John to
provide the funding, he would be treating Mary as an end, insofar as he
would be acting to facilitate her realization of her own ends. Of course, as
was pointed out in the previous discussion of imperfect duties, it is not
humanly possible for one’s every action to be one of actively treating (in
the sense of furthering) others as ends. Nevertheless, there is an imperfect
duty to hold the principle of actively treating or furthering others as ends,
and to act on this principle in appropriate circumstances. John may not be
specifically required to provide funding for Mary, but he does have an
imperfect duty, in a range of circumstances that seem appropriate to him,
to use his personal resources to actively treat or further other rational
beings as ends. Thus, it is a perfect duty never to treat oneself or another
rational being as a means only, and an imperfect duty to actively treat or
further all rational beings as ends in themselves.
The third formulation of the categorical imperative, the
principle of autonomy, and duty
Although Kant expresses his third formulation of the categorical
imperative in a number of ways, its clearest statement may be in the
“principle of autonomy.” According to this principle one is only subject to
the moral law that one has legislated for oneself: “Never choose except in
such a way that the maxims of the choice are comprehended as universal
law in the same volition” (FMM, 57). Although this principle seems quite
similar to the first formulation of the categorical imperative, the important
difference is that this principle requires one to think of the universal laws
as issuing from one’s own volitions, and thus that the constraints to which
one is subject come from one’s own will. Kant’s point is that rational beings
are not merely subject to the moral law, but subject to the law because they
created it themselves, i.e. because the law comes from their own will.
To understand the importance of autonomy for morality one must
consider Kant’s views on “good will” and “duty.” While other things might
be good toward one end or another, or when employed in one way or
another, Kant says that the only thing that is good without qualification is
the good will (see FMM, 9–10). Kant then reveals the nature of the good
will in a discussion of duty (see FMM, 12–15). Kant argues that acts do not
have moral worth merely because they accord with duty, but only if they are
done from (the motive of) duty. For example, if a shopkeeper gives a young
child the correct change because they know that it is good for business, or
even if someone helps another in need because they like to be helpful,
although the acts accord with duty, they have no true moral worth. Kant is
not saying that it is bad for people to behave in these ways, but only that
they do not warrant moral esteem. In all the cases in which people behave in
accord with duty, but for reasons other than just the requirements of duty,
the person is moved by some particular interest, even if it is only the good
feeling that they get inside. In all of these cases the person is acting out of
some particular interest, and not merely manifesting a good will. The good
will is only manifest when one does one’s duty, not from any particular
interest, but precisely because it is one’s duty.
Now the importance of the principle of autonomy can be clear. Imagine
that rational beings were subject to a moral law that they had not created
for themselves. If the moral law did not come from the rational being’s
own will, then there would have to be some influence external to this
being that moved it to act in conformity to the law. Obedience to the
moral law would then be conditional on rational beings responding in a
certain way to this external influence. For Kant, however, this would be
antithetical to morality. Obedience might accord with duty, but it would
not be from duty, it would not manifest a good will, and it would have no
true moral worth.
Kant concludes that the principle of autonomy expresses the
fundamental claim of his moral theory:
That the principle of autonomy, which is now in question, is the sole
principle of morals can be readily shown by mere analysis of
concepts of morality; for by this analysis we find that its principle
must be a categorical imperative and that the imperative commands
neither more nor less than this very autonomy.
(FMM, 58)
The concept of morality entails the idea of an absolute law, and, therefore,
the fundamental moral principle must be a categorical imperative. But
when one thinks about this imperative one recognizes that, since the
imperative must be absolute, it cannot be based on anything of
contingent interest. This requirement eliminates all principles that have
their source outside of the individual, and leaves only the principle of
autonomy.
Why people are subject to the categorical imperative
So far it has been shown that if there is such a thing as morality, then its
rule is expressed by the categorical imperative (in all of its alternative
formulations) that Kant has provided. What has not been shown is that
beings like ourselves are subject to this morality. Kant has shown that it is
essential to the concept of the categorical imperative, through the principle
of autonomy to which it leads, that, if there is to truly be a categorical
imperative, then it must be adopted by rational beings for themselves. But
why would rational beings adopt the categorical imperative? Kant’s
answer is that, insofar as rational beings take themselves to be rational,
they necessarily recognize the categorical imperative as a constraint upon
themselves. Kant is saying that a necessary component of the self-image of
rational beings is their recognition of the fact that they must constrain
themselves in accord with the categorical imperative. Here again one can
see that Kant is using an a priori argument based on the concept “rational
being” to support his moral theory.
Kant’s transcendental argument for his moral theory takes the
following form. First he argues that there is a relationship between
freedom and autonomy such that all beings who consider themselves free
must accept the principle of autonomy, which, as was previously
discussed, entails the categorical imperative (FMM, 64). Then he shows
that rational beings, because of how they experience the world, and,
specifically, their own activity in the world, must consider themselves free
(FMM, 65). Thus, it follows that rational beings must think of themselves
as constrained by the categorical imperative. An explanation of this
transcendental argument for the categorical imperative best begins with an
account of his view of freedom.
Rational beings have wills, and they cause things to happen in
the world through their wills. Kant says of the will of rational
beings that
freedom would be that property of this causality by which it can be
effective independently of foreign causes determining it, just as
natural necessity is the property of the causality of all irrational
beings by which they are determined to activity by the influence of
foreign causes.
(FMM, 63)
This is Kant’s view of negative freedom, i.e. freedom from determination
by something external to the will. The idea is that if one’s will is free in
this negative sense, then, as opposed to existing merely as a sensible or
physical being, subject to strict causal determinism, one must also exist as
an intelligible or purely rational being that can have effects on the world
independently of any foreign influences one experiences.
Kant claims that this negative conception of freedom opens the door to
a positive one. Kant has said that the will is a kind of causality that, free in
the negative sense, is not determined by foreign influences. One must
recognize, however, that “the concept of a causality entails that of laws
according to which something (i.e. the effect) must be established through
something else which we call cause” (FMM, 63).
So how is a will that is free in the negative sense determined? It is clear
from the concept of “causality” that a free will must be determined in
accord with some law. This is also confirmed by common sense. To
imagine a will that is not determined in accord with some law, is to
imagine a will that is random. But a being whose will appears to be
random is not thought of as free, but is ushered away by people in white
coats. Such a will does not accord with the concept of “freedom.”
To be free, therefore, a will must be determined in accord with some
law. It cannot be determined by the laws of nature, for determination by
the laws of nature is exactly what accounts for the lack of negative
freedom in sensible or physical beings. Thus, a will that is free in the
positive sense must determine itself, it must act in accord with a law that it
adopts for itself, a law of freedom. This, however, is exactly what it is to
be autonomous, and therefore to recognize oneself as subject to the
categorical imperative. After all, the categorical imperative is the only
principle of the will that beings can adopt for themselves, since all other
imperatives are based on ends that are of contingent value, and, thus,
entail rational beings’ determination by things external to themselves.
Kant concludes this discussion by stating that “a free will and a will under
moral laws are identical” (FMM, 64).
Kant still hasn’t shown either that rational beings have free wills, or
that there are any beings in the world that are subject to the morality that
he has described. What has been shown is that only free beings can be
subject to morality, and, more importantly, that all beings that think of
themselves as free must think of themselves as subject to morality. Thus, if
Kant demonstrates that rational beings necessarily think of themselves as
free, then he will have shown that rational beings must think of themselves
as subject to the categorical imperative. And if this demonstration is based
on the way that rational beings necessarily experience themselves in the
world, then Kant will have provided a transcendental argument that
rational beings are subject to the categorical imperative. So the question is:
Do rational beings experience themselves in the world in a way that
requires them to think of themselves as having a free will?5
What is it to think of oneself as a rational being? To think of oneself
as rational is to think that one applies reason (competently) when
making judgments. The following is an example of applying reason when
making a judgment: If a rational being knows that if statement P is true
then statement Q is true, and also knows that P is, in fact, true, then, if
it actually manifests its rationality, it will conclude that Q is true,
through the application of a certain, in this case obvious, principle of
logic. A being that came to hold that Q is true without having applied
the principle of logic, say because Q just popped into its mind, would
not be thought of as having made a rational judgment (regardless of the
truth of its belief). Furthermore, even a being who applied the principle
of logic, if it did so out of instinct, or because it was forced to by some
external power, would not be thought of as having (itself) made a
rational judgment. Calling a judgment rational, and, by extension, a
being rational insofar as it makes rational judgments, is only appropriate
when the being has itself adopted and correctly applied the relevant
principle of logic. If the being does not do this for itself then it is like a
simple computer (one for which there is no question of artificial
intelligence). It never deserves credit for the conclusions that it draws
because its application of logical principles is solely the result of forces
external to itself, e.g. the skill of its programmer.
Thus, with respect to logical judgments, a being can only think of itself
as rational if it thinks that it has adopted and applied the principles of
logic for itself. Of course, one can adopt and apply these principles for
oneself only if one is free in Kant’s positive sense. Thus, to think of oneself
as rational, at least in one’s logical judgments, one must think of oneself as
free, and as having freely adopted the laws of logic. Nevertheless,
although one must freely adopt these laws if one is to think of oneself as
rational, that does not necessarily mean that one could adopt some other
laws of logic and still think of oneself as rational. It is quite possible
(though there are some who would question this claim) that there is only
one set of fundamental logical laws that one can adopt without belying
one’s rationality. One’s freedom is still manifest, however, by the fact that
one has adopted the laws of logic for oneself, even though there is only
one set of logical laws that one can adopt as a rational being.
The situation with regard to morality is analogous. To consider oneself
possessed of practical reason, i.e. to think that one applies reason in
determining one’s will and consequently one’s actions, one must think of
oneself as freely adopting one’s principles of action. In other words, one
must think of oneself as having a free will. However, the fact that one
must be free in adopting one’s principles of action does not mean that
there must be some range of options for one to select from among. As
appears to be the case with logic, in the case of morality, there is exactly
one fundamental principle of action that can be freely adopted, and that is
the categorical imperative.
These considerations lead to a common confusion with respect to Kant’s
views on freedom, which can be expressed in the following question: How is
it possible for one both to be free and to have to adopt the categorical
imperative? This question manifests a misunderstanding of what Kant
means by freedom. By freedom Kant does not mean the option of choosing
one thing or another (which one might also call liberty), but rather, the
power of self-determination (which can also be called autonomy).
Kant’s point is that if the moral law is truly to be freely adopted, then it
cannot get its force from any contingent conditions external to the individual.
However, the only principle of action that is independent of determination by
any contingent external influences is the categorical imperative. Therefore,
insofar as one thinks of oneself as a rational being, possessed of practical
reason, one must think of oneself as subject to the categorical imperative.
A second common confusion with respect to Kant’s views on freedom
is that he thinks that people are free only when they act in accord with
the categorical imperative. The concern is that Kant is claiming that
people are not acting freely on those occasions when they succumb to the
influence of their inclinations and act contrary to the categorical
imperative. If this were true it would raise quite a problem, because it
entails the claim that people who act immorally are not free, and
therefore cannot be held responsible for their actions. Kant, however,
thinks of all rational beings as free insofar as they recognize the
categorical imperative as a constraint upon their actions. Those who
violate this constraint, insofar as they are rational, recognize that they
have done wrong exactly because they recognize the categorical
imperative as a proper constraint upon their wills (FMM, 41). A being
who violates the categorical imperative, and does not recognize that it
has done wrong, must not have adopted the categorical imperative as a
constraint upon its will. Such a being cannot think of itself as rational.
Thus, the categorical imperative expresses the definitive principle of how
rational beings ought to act.
PART II: KANT’S POLITICAL PHILOSOPHY
In his political writings Kant builds upon the foundations he established
principally in his moral philosophy to provide a rather strong argument
supporting the necessity and the legitimacy of the state. In particular, he
argues that there must be a single institution among a people, which he
calls the state, that has the authority to use coercion to force people to
leave others free to formulate and pursue the ends of their choice,
provided that they are not violating the similar freedom of another. Kant
argues both that morality requires people to exist within a state that
secures their freedom to formulate and pursue the ends of their choice,
provided that they do not violate the similar freedom of others, and that
morality permits people to use coercion to force others to be members of
such a state.
Kant suggests that his argument for the state grows out of the
consideration of how human beings are actually to apply the categorical
imperative (MM, 16).6 Nevertheless, this approach does not reveal all of
Kant’s concerns in his argument for the state. Accordingly, I will also
discuss Kant’s argument that people necessarily view themselves as having
a certain role to fulfill in the world, and that they can only perform this
role successfully if their freedom to formulate and pursue the ends of their
choice is secured within a state.
The domain of jurisprudence, the ends of nature, and the
value of external freedom
Kant’s Metaphysics of Morals addresses the issue of how the categorical
imperative is to be applied by human beings. This work is divided into two
parts: the “Doctrine of Right,” in which Kant expresses much of his
political philosophy, and the “Doctrine of Virtue,” which is concerned
exclusively with other aspects of his moral philosophy. Ostensively, the
basis for Kant’s division of the work is the difference between duties of
justice, juridical (legal) duties, and duties of virtue, ethical duties (MM,
18–21). Kant says that all legislation (juridical and ethical) consists of two
elements: the law, and the incentive to obey the law.
Although two different types of legislation may agree about the law,
e.g. both juridical and ethical legislation may prohibit murder, they can at
the same time differ with respect to their incentives:
If legislation makes an action a duty and at the same time makes this
duty the incentive, it is ethical. If it does not include the latter
condition in the law and therefore admits an incentive other than the
Idea of duty itself, it is juridical.
(MM, 19)
Kant is distinguishing ethics, according to which one must always do one’s
duty exactly because it is one’s duty, and never for any other reason, from
jurisprudence, according to which one can have some other incentive for one’s
actions that fulfill one’s duties. In fact, Kant begins the “Doctrine of Right” by
defining jurisprudence as “the body of those laws that are susceptible of being
made into external laws, that is, externally legislated” (MM, 33)7 Thus, one
must determine exactly what laws can be externally legislated.
First we should consider the difference between perfect and imperfect
duties, and whether the laws that correspond with each of these can be
externally legislated. Perfect duties require the performance or
nonperformance of specific actions. It is easy to imagine how laws
corresponding to these duties could be externally legislated, as it is easy to
imagine how external incentives could be employed to coerce people either
to perform or to refrain from performing specifie actions.
It seems impossible, however, for external incentives to be employed to
coerce people to perform imperfect duties (MM, 45). After all, imperfect
duties require people to adopt certain principles (e.g. beneficence), and to
act on those principles in circumstances that they deem appropriate. But
people cannot be coerced either to adopt principles or to act on them.
Since people’s wills are always free, and adopting a principle is an act of
will, people cannot be forced to adopt principles. Furthermore, although
people can be coerced to perform acts that follow from specified
principles, since the act is merely a response to the coercion, it cannot be
construed as an attempt to act in accord with the specified principle. Thus,
people cannot be forced to act on a principle. Therefore, only imperfect
duties can be the subject matter of jurisprudence, imperfect duties cannot.
It might appear, then, that all perfect duties can be addressed by
jurisprudence. Actually, however, there is good reason to believe that Kant
means to exclude perfect duties to oneself from the domain of
jurisprudence.8 One clear statement to this effect follows: “The concept of
justice…applies only to the external and—what is more—practical
relationship of one person to another” (MM, 34). One can best
understand Kant’s political philosophy, and specifically his exclusion of
perfect duties to oneself from the domain of jurisprudence, by considering
the broadest concerns that motivate him to write about the state.
In a number of his writings, including some essays on history and, more
importantly, the Critique of Judgment, Kant reveals a great concern
for the development of humanity. In the Critique of Judgment, Kant’s
interest in the development of humanity is revealed in the context of an
extended discussion of teleology or purpose. He argues that people can
only make sense of a thing insofar as they understand it in terms of its
purpose (CJ, 280).9 The notion of a thing having a purpose, however, is
ambiguous, raising two issues, each of which is relevant (CJ, 312–13).
Something can be organized in a way that manifests a purpose internal to
the entity, as a tree is organized to grow and reproduce, or the manifest
purpose can be external to the entity, as a tree is organized to help
maintain the proper oxygen level in the atmosphere for animals to survive.
When the question of purpose is asked of nature itself, the answer is
quite revealing about humanity. Kant thinks that the ultimate internal
purpose of nature is human culture, by which he means the ability of
human beings, as sensible or physical beings constrained by the laws of
nature, to formulate and pursue whatever ends they may set for
themselves (CJ, 317–21). But human culture in this sense can only develop
if people are secure from others interfering with their ability to formulate
and pursue the ends of their choice. Thus, the greatest development of
human culture, the ultimate end of nature, can only be realized if people
do not violate their perfect duties to others (“UH,” 45–6).10 However,
since the violation of perfect duties to oneself would also inhibit the
development of human culture, it is not yet clear why Kant restricts the
role of the state to include the enforcement of only perfect duties to others.
Kant’s reason for excluding perfect duties to oneself from the domain of
jurisprudence is revealed through the consideration of his views on the
final external purpose of nature (CJ, 322–3). The final external purpose of
nature can only be manifest in something that makes use of nature, but is
not itself a part of nature, i.e. is not subject to the laws of nature,
otherwise it would merely be one more internal purpose of nature. It is
human beings, insofar as they are intelligible, or purely rational, beings
subject to the moral law, who provide the final purpose for all that exists
within nature. However, to the extent that people are not acting on the
moral law, but are responding to their inclinations, nature is not being
used toward any ends that themselves come from outside of nature. Thus,
the final end of nature is only realized to the extent that humanity has
developed toward moral perfection.
Kant, however, thinks that the final end of nature cannot be realized so
long as people remain in the state of nature because morality is necessarily
inefficacious when people remain in this condition. Among people who
choose to remain in the natural condition, without a state that enforces
the fulfillment of perfect duties to others, it is as if they have agreed with
one another that anything goes:
If men deliberately and intentionally resolve to be in and to remain
in this state of external lawless freedom, then they cannot wrong
each other by fighting among themselves; for whatever goes for one
of them goes reciprocally for the other as though they had made an
agreement to that effect.
(MM, 72)
In such circumstances, there is reason to believe that none of the duties that
people have to one another will be fulfilled. Thus, only if there is a state that
enforces the fulfillment of perfect duties to others is it possible that morality
will develop to the point that all duties to others can regularly be fulfilled.
Therefore, the existence of the state is viewed by Kant as a necessary
condition for the development of morality.
It is now clear that Kant requires a state that enforces at least the
fulfillment of perfect duties to others, but why should it not also enforce
the fulfillment of perfect duties to oneself? The problem is that the
enforcement of perfect duties to oneself would undermine the development
of the moral character necessary among people who are to fulfill all of
their ethical duties. Although the argument is too involved to pursue fully
here, the basic point is that one’s perfect duties to oneself are fundamental,
and only one who truly fulfills these duties, i.e. fulfills them precisely
because they are duties, can develop the character necessary for the
fulfillment of all of their duties. But if one is coerced to fulfill these duties
to oneself, instead of fulfilling them solely because they are one’s duties,
this will undermine the development of one’s character as one who fulfills
all one’s duties.11 Thus, although the external legislation of perfect duties
to oneself may facilitate the realization of the ultimate end of nature, it
would actually undermine the development of humanity toward moral
perfection, the final end of nature. Kant’s greatest interest, the
development of humanity toward both the ultimate and final ends of
nature, can be realized only within a state that enforces the fulfillment of
perfect duties to others, thereby securing people’s external freedom and
permitting them to formulate and pursue the ends of their choice, provided
that they leave a similar freedom for others.
External freedom and the concept of justice
Having, at least briefly, explained Kant’s non-political reasons for being
concerned with securing people’s external freedom, the foundation has
been laid for showing how Kant argues within his political philosophy
from the presumed value of external freedom to the necessity and
legitimacy of a state that uses coercion to force people to fulfill their
perfect duties to others. The outline of Kant’s argument is as follows:
1 People have an innate right to external freedom.
2 The only legitimate limitation on this right to external freedom is the
right of others to a similar freedom.
3 The condition of the universal realization of this right to external
freedom is the condition of justice.
4 Justice entails the authorization to use coercion, as necessary, to
support the condition of justice.
5 The innate right to external freedom entails both
a the right to security in oneself, and
b the right to possess things external to oneself.
6 Someone who remains in proximity, and in the natural condition
relative to others, i.e. not in a state, interferes with their external
freedom by not providing them a guarantee of security with respect to
both
a their right in themselves, and
b their rightful possession of objects external to themselves.
7 Existing within a state, subject to juridical law, is the only way to
guarantee this security to others.
8 It is just to use coercion to force anyone in proximity into a state,
subject to juridical law.
Kant claims that there are two types of rights: innate rights and acquired
rights (MM, 43). Innate rights belong to people by nature, independently
of any act of law. Acquired rights, on the other hand, only come to exist
through an act of law. Since acquired rights are dependent on acts of law,
they cannot themselves provide the basis for considering people obligated
to accept the lawful authority of a state. Any right that is to provide a
legitimate basis for considering people obligated to accept the authority of
a state must be an innate right. The innate right of external freedom plays
this crucial role in Kant’s argument for the necessity and the legitimacy of
the state. Kant begins the section entitled “There is only one innate right”
as follows:
Freedom (independence from the constraint of another’s will),
insofar as it is compatible with the freedom of everyone else in
accordance with a universal law, is the one sole and original right
that belongs to every human being by virtue of his humanity.
(MM, 43–4)
The innate right to external freedom, therefore, is the only right that can
provide the justification for imposing a system of juridical law on others.
This innate right to external freedom provides the basis for Kant’s
conception of “justice,” which he defines as “the aggregate of those
conditions under which the will of one person can be conjoined with the
will of another in accordance with a universal law of freedom” (MM, 34).
What are the conditions under which people’s wills can be conjoined in
accordance with a universal law of freedom? Kant thinks that two wills
can be conjoined if they include no incompatibility. But what does this
mean? Following Kant’s description of willing as “the summoning of all
the means in our power” (FMM, 10), two wills can be conjoined if each
will, while summoning all of the means in its power applicable toward its
end, does nothing incompatible with the activity of the other.
Suppose that two people will to hold the same political office. They will
both summon all of the means that are in their power to gain this office,
which, taken to its literal extreme, will undoubtedly include the violent
elimination of their rival. In this case their wills cannot be united since
each of them, by seeking to eliminate the other, is acting in a manner that
is incompatible with the other’s pursuit of the goal. It is not possible for
them jointly to will that they act in the manner described, since it entails
both of them willing their own death, and also willing to survive after the
death of the other.
The question of justice, however, is not merely whether their wills can
be conjoined, but whether they can be conjoined in accordance with a
universal law of freedom. This restricts the range of maxims upon which
they can will to act to those that are in accord with the universal law of
freedom, which, for human beings, is expressed in the categorical
imperative. If the rivals restrict their wills to maxims that meet this
requirement, then they each will act on no maxim (employ no means) the
universalization of which would be incompatible or inconsistent with the
freedom of the other to act on similarly acceptable maxims. If the
politicians so restrict themselves, then all of their acts, e.g. distributing
buttons, or advertising their virtues on television, will be compatible with
the like freedom of others. Their wills can be conjoined since there is no
incompatibility or inconsistency between their willing to act in this
restricted manner, and others willing to act similarly.
Although it was made to seem above, during the discussion of the
universal law of freedom and its relationship to the categorical imperative,
that justice requires one to act fully in accord with the categorical
imperative, it is clear from Kant’s definition of justice that it is limited to
perfect duties to others. The exclusion of duties to oneself is clear from the
reference to conjoining the will of one person with the “will of another.”
The exclusion of imperfect duties is entailed by the reference to the
conditions in which one person’s will “can be conjoined” with that of
another. When asking if the wills can be conjoined, one is asking only
whether it is logically possible for the maxims to hold at the same time,
the test for perfect duties, not whether one could will them to hold at the
same time, the test for imperfect duties.
With this understanding of Kant’s conception of justice, it is easy to see
that it amounts to nothing more than the condition of the universal
realization of the innate right to external freedom. For all people to be
independent of the constraint of others’ wills, to the extent that this is
compatible with the freedom of everyone else in accordance with a
universal law, i.e. for the innate right to external freedom to be universally
realized, requires neither more nor less than that people be in a condition
in which their wills can be conjoined in accordance with a universal law of
freedom, i.e. that people be in a just condition. Thus, if Kant can argue
that the concept of justice logically entails the right to use coercion in
support of the condition of justice, then he will have shown that there is
no inconsistency in using coercion to support and maintain external
freedom.
Kant wants to show that such coercion as is truly employed in
opposition to injustice is itself consistent with justice (MM, 35–6). It
follows from Kant’s definition of justice that injustice would be any
condition in which one person’s will could not be conjoined with the will
of another in accordance with a universal law of freedom. This condition
cannot be eliminated, but can only be furthered, by an act that is itself
unjust. Since every unjust act entails a will that cannot be conjoined with
at least one other will in accordance with a universal law of freedom,
every unjust act itself necessarily furthers the existence of the condition in
which one person’s will cannot be conjoined with the will of another in
accordance with a universal law of freedom, i.e. the condition of injustice.
Thus, any coercion that actually opposes the condition of injustice must,
by definition, itself be just.
Kant goes on to argue that it is not merely just, but required by justice,
to use coercion against anyone who acts unjustly (MM, 36–7). Of course,
there are conditions on how that coercion is to be justly applied, but,
assuming that these conditions are met, the application of coercion in
support of the innate right to external freedom is itself a requirement of
justice. It is particularly important to Kant, in light of the broadest
concerns of his political philosophy, that external freedom can be
supported by coercion. He is concerned with external freedom because it
is a necessary condition for the development of humanity toward the final
end of nature, moral perfection. But if people have to be moral to respect
one another’s external freedom, then Kant would have a circular argument
in which the conditions for the development of morality were themselves
dependent on morality. Kant needs the condition in which people respect
one another’s external freedom to be established entirely independently of
the morality of the people. Thus, it is essential for Kant’s argument that
external freedom can be supported entirely by external legislation
(independent of people’s internal moral motivations).
The components of external freedom
Having shown that coercion can and ought to be used in support of the innate
right to external freedom, the question of exactly what is entailed in this right
must now be addressed. Based on his definition of the innate right to external
freedom it is clear that Kant wants people to be independent of constraints
that come from the will of others, when they are formulating and pursuing the
ends of their choice in a manner consistent with others having a like freedom.
It would seem then that Kant thinks that the innate right to external freedom
entails independence from others willfully acting in a way that interferes with
one’s right to formulate and pursue the ends of one’s choice. A right to this
son of freedom may be commonly recognized, and may provide an adequate
basis for a derivation of the necessity and legitimacy of the state. However, it
is clear from Kant’s argument for the state that he has a significantly stronger
sense of “freedom” in mind. This freedom includes independence from others
willfully acting in a way that interferes with one’s right to formulate and
pursue the ends of one’s choice in a manner consistent with the similar
freedom of others, but it also includes independence from otherseven
willfully maintaining a condition that interferes with this right
(see MM,35).
If he is to provide an a priori argument for the necessity of the state, Kant
has to be concerned with the possibility of one’s external freedom being
interfered with by the conditions that others maintain, and not only by their
actions. Kant’s argument is dependent on the fact that someone who is in
proximity, and in the natural condition relative to others, necessarily
interferes with their external freedom. If Kant based his argument for the state
on the fact that people will commit acts that interfere with the external
freedom of others, then his argument for the state would be contingent on
people actually committing such acts. Thus, Kant says:
I am injured by the condition of other people who are in the natural
state. For [when others remain in the natural condition] I have no
security and my property is always in danger. I am not obligated to
remain in this fear.12
Kant’s point is that people who remain in proximity, and in the state of
nature relative to others, interfere with others’ freedom by interfering with
both their security in themselves and their right to things external to
themselves. Furthermore, one need not tolerate this situation of insecurity
that undermines freedom, because people can be forced to join the state, the
only condition in which freedom is guaranteed, without violating their
freedom.
The last two sentences constitute, in effect, a restatement of steps 5–8
of Kant’s argument as outlined above. According to the innate right to
external freedom, people have the right to formulate and pursue the ends
of their choice, provided that they leave a similar freedom for others. Kant
thinks that this right entails both the right to security in oneself and the
right to possess things external to oneself.
Any violation of one’s right in oneself, which would seem necessarily to
involve some son of assault, clearly entails the victim’s being constrained
by the will of another (the perpetrator). Furthermore, Kant thinks that
even the threat of a violation of one’s right in oneself interferes with one’s
external freedom, as Hobbesian reasoning reveals. If people are in fear for
their personal security, they will have to focus a great portion of their
efforts on securing themselves, and will not be able to formulate and
pursue those ends that truly interest them. Thus, the innate right to
external freedom entails the right to security in oneself.
The explanation of why the innate right to external freedom entails the
right to possess things external to oneself is much more complicated. One
simple explanation that Kant alludes to at times is that human culture is
advanced through people engaging in complex projects, but people will
only engage in such projects if they have a fixed expectation of their
efforts being undisturbed, and of being able to work from the results of
earlier efforts in subsequent, more involved projects. Thus, the right to
possess things external to oneself is necessary for the development of
human culture, the ultimate end of nature. Kant’s more complicated
explanation of the right to property is basically that freedom can only be
restricted to preserve the like freedom of others, owning property does not
restrict the like freedom of others, and, therefore, freedom includes the
right to own property. Thus, to restrict the possibility of the rightful
possession of things external to oneself is to restrict freedom for something
other than freedom, which is necessarily inconsistent with the final end of
nature (MM, 52–3).
The necessary conditions of external freedom
What remains to be shown is that anyone who remains in proximity, and
in the natural condition relative to others, interferes with both of the
rights that are entailed in the innate right to external freedom. First we
shall look at Kant’s argument that such an individual interferes with
others’ right to possess things external to themselves. Kant maintains that
the right to possess anything, although land is the most important
example, depends on a relationship of the wills of all those who are in
proximity (MM, 65). There are no material conditions, which could be
verified empirically, that constitute having a right to a thing. Although
Locke argued that one can make something one’s property by mixing
one’s labor with it, Kant would respond that this begs the question, since
it can now be asked: By what right does one mix one’s labor with
something?
Kant thinks that a person can rightfully possess something only if
everyone in proximity relinquishes their right to will the use of that thing.
Thus, one cannot take rightful possession of something through one’s own
will alone; there must be a union of wills manifesting the agreement of all
to respect the property of each:
Now, with respect to an external and contingent possession, a
unilateral Will cannot serve as a coercive law for everyone, since that
would be a violation of freedom in accordance with universal laws.
Therefore, only a Will binding everyone else—that is, a collective,
universal (common), and powerful Will—is the kind of Will that can
provide the guarantee required. The condition of being subject to
general external (that is, public) legislation that is backed by power
is the civil society. Accordingly, a thing can be externally yours or
mine only in a civil society.
(MM, 65)
For Kant, existing within a state is the form in which the people express
their mutual respect for one another’s rightful possession of things
external to themselves. What happens, however, if there are people in
proximity, and in the state of nature relative to the others? These people
are not parties to the union of wills by which each person’s rightful
possessions are guaranteed. These people are in a position to will the use
of things that would otherwise be rightfully possessed by others. But since
rightful possession depends on the agreement of the wills of all those in
proximity, the presence of these people who are outside the union of wills
makes rightful possession impossible, thereby interfering with the freedom
of those within the union. Thus, Kant concludes this discussion by saying
that if rightful possession must be possible (and it is entailed in the innate
right to external freedom), “then the subject must also be allowed to
compel everyone else with whom he comes into conflict over the question
of whether such an object is his to enter, together with him, a society
under a civil constitution” (MM, 65). In summary, Kant argues that the
innate right to external freedom includes the right to possess things
external to oneself; that this right can only be realized within a state; that
anyone in proximity and outside of the state interferes with this right; and,
therefore, that it is just to use coercion to force such people to enter the state.
Kant also argues for the necessity and the legitimacy of the state from
the fact that the innate right to external freedom entails a right to security
in oneself that can only be realized within a state. While it is true that
everyone has an ethical duty to respect everyone else’s rights in themselves,
nevertheless, since people have no way of knowing the intentions of
others, they are not secure in their rights in themselves until such time as
they guarantee to one another that they will respect these rights:
The necessity of public lawful coercion does not rest on a fact, but
on an a priori Idea of reason, for, even if we imagine men to be ever
so good natured and righteous before a public lawful state of society
is established, individual men, nations, and states can never be
certain that they are secure against violence from one another.
(MM, 76)
Kant’s point is that, despite the requirements of morality, people’s rights in
themselves are insecure outside of a state. Paralleling his argument for the
state from the right to possess things external to oneself, Kant argues here
that the only way that the rights entailed in the innate right to external
freedom can be realized is if people make their will not to violate these
rights publicly known, and that the form of this mutual guarantee is the
state.
Kant’s argument that the necessity and the legitimacy of the state can be
derived from the fact that people have the right to security in themselves is
well summarized in the following:
It is usually assumed that one cannot take hostile action against
anyone unless one has already been actively injured by them. This is
perfectly correct if both partics are living in a legal civil state. For the
fact that one has entered such a state gives the required guarantee to
the other, since both are subject to the same authority. But man (or
an individual people) in a mere state of nature robs me of any such
security and injures me by virtue of this very state in which he
coexists with me. He may not have injured me actively (facto), but
he does injure me by the very lawlessness of his state (statu iniusto),
for he is a permanent threat to me, and I can require him either to
enter into a common lawful state along with me or to move away
from my vicinity.
(“PP,” 98 n.)13
The innate right to external freedom can be universally realized only
within a state, in which each person guarantees this right of everyone else
by participating in a union of wills resolved to use coercion in support of
this right. Furthermore, since it is just to use coercion in support of the
innate right to external freedom, it is just to use coercion to force into the
state those people who would otherwise maintain a condition that
interferes with the external freedom of others (e.g. by remaining in
proximity and outside of civil society).
Kant on international relations
Before discussing Kant’s views on how one is forced to join a state, and the
version of hypothetical social contract theory toward which these
concerns lead Kant, it is interesting to consider the relationship between
Kant’s argument for the necessity of the state and his views on
international relations. Kant has argued that people who remain in
proximity, and in the natural condition relative to others, because they
necessarily interfere with the freedom of those others, may therefore justly
be forced to join together with them in a state that secures their freedom.
However, what if these people are already members of a state, but a
different neighboring state? Two related problems arise: First, the
members of each state interfere with the freedom of the members of the
other state just as they would if they were not members of a state at all: if
there is no formal relationship between the states, there is no guarantee
that the members of each state will respect the rights of the members of
the other state. Second, the two states, which can each be thought of as a
“moral person,” are in the state of nature relative to one another, and
suffer all the difficulties that led Kant to argue for the need for civil
society.
Kant recognizes that these are serious difficulties which, unchecked,
would very much undermine the possibility of the sort of human
development that he thinks should be facilitated. His solution to the
problem is to suggest that the same forces that lead individuals into a state
should lead states into a federation of states (“PP,” 102–5; “UH,” 47;
“TP,” 90).14 This federation of states would then fulfill the same role
among states that a state fulfills for its citizens, and would also provide the
necessary guarantee of external freedom among the citizens of different
states.
Although it is clear what Kant provides through his suggestion of a
federation of states, there is also a significant problem raised by this
suggestion: Who is ultimately sovereign? Since Kant argues that for a
state effectively to fulfill its role it must be ruled by an absolute
sovereign, it would seem to follow that the federation of states can
effectively fulfill its role only if it is ruled by an absolute sovereign. Thus,
it appears to be a clear implication of Kant’s argument that there
should be a single world nation, without lesser sovereign states.
However, Kant never supports the notion of a single world state, and at
one point discusses the concern that such a world state “may lead to
the most fearful despotism” (“TP,” 90). Thus, while Kant was right to
recognize that his argument for the necessity and the legitimacy of the
state has important implications for international relations, he was
never able to give a clear and satisfactory account of how those
international relations should be organized.
Kant’s hypothetical social contract theory
Kant has shown that people who remain in proximity, and in the natural
condition relative to others, can be forced to join together with others in a
state. Before one can understand what Kant thinks is entailed in forcing
someone to join a state, one must understand what Kant thinks is entailed
in being a member of a state, and how this membership is manifest. These
issues are all addressed by what might best be described as a hypothetical
social contract theorist.
Kant’s hypothetical social contract theory follows from his a priori
reasoning about human beings, and his recognition of both the rights of
human beings, and the impossibility of realizing those rights outside of a
state:
A state (civitas) is a union of a multitude of men under laws of
justice. Insofar as these laws are necessary a priori and follow from
the concepts of external justice in general (that is, are not established
by statute), the form of the state is that of the state in general, that is
the Idea of the state as it ought to be according to pure principles of
justice. This Idea provides an internal guide and standard (norma)
for every actual union of men in a commonwealth.
(MM, 77)
Kant is concerned with the Idea of the state, which is based on a priori
necessary laws of justice, and thus ought to serve as the blueprint for all
actual states. It is the possibility of deriving the state a priori that grounds
the possibility of a hypothetical social contract theory.
Kant is a social contract theorist, maintaining that one’s political
obligations can only result from one’s having consented, along with
others, to be subject to the authority of the state. Kant, however, departs
from the more traditional social contract theorists in that he does not
think that this consent is actual, either explicit or tacit. Thus, Kant’s
social contract theory is best described as hypothetical, to distinguish it
from those theories according to which people must actually manifest
their consent through their behavior. Under Kant’s hypothetical social
contract, human beings can be treated as if they have consented to the
social contract, because their consent is a necessary manifestation of
their humanity, i.e. it is known a priori that, inasmuch as a being is
rational, and one to whom the concept “human” applies, this being
necessarily consents to the social contract. Thus, Kant says that being a
member of a state is a “requirement of pure reason, which legislates a
priori” (“TP,” 73).
It is in accord with this pure reason that people are parties to the social
contract, and organize themselves into a state. Being organized into a
state, however, does not require that individuals actually apply their own
reason and recognize the necessity and the legitimacy of the state; rather,
the state is legitimate because a priori reason reveals it to be so: “The act
by means of which the people constitute themselves a state is the original
contract. More precisely, it is the Idea of that act that alone enables us to
conceive of the legitimacy of the state” (MM, 80).
Kant places himself in the contract tradition through his reference to
the “original contract.” However, he then avoids any reliance on the
actuality of this contract, and introduces what I have called a hypothetical
social contract theory. It is not any actual social contract, to which people
have actually consented either explicitly or tacitly, that lies at the
foundation of the state and accounts for its legitimacy. Rather, it is the
“Idea” of the original contract, a necessary idea of a priori pure practical
reason that must, therefore, necessarily be assented to by all human beings
inasmuch as they manifest their rationality, that provides the foundation
of the state, and accounts for its legitimacy.
All that is required for one to be a member of a state, remembering that
it requires no actual consent, is to exist in a condition in which each
individual has the rights and obligations that are necessary for the
maintenance of a just condition, and which are enforced by the state
through coercion. In fact, Kant argues that even if the state does not
enforce exactly those rights and obligations that are necessary for the
maintenance of a just condition, people must still accept its authority (for
reasons that will be revealed shortly). In any case, membership in the state
amounts to nothing more than the fact that citizens have an obligation to
obey the law, and will be punished if they do not. There is nothing that
manifests citizens’ membership in the state save the fact that a priori pure
practical reason requires people, as intelligible beings, to subject
themselves to this system of laws, and that people, as sensible or physical
beings, are actually subjected to the authority of the state.
What about those people existing either within the borders of the
state, or otherwise in proximity, who, as intelligible beings, do not
recognize the a priori practical necessity of subjecting themselves to the
authority of the state, and, therefore, as sensible or physical beings, do
not necessarily obey the authority of the state? Kant has said that such
people can be forced to join the state. But, since there is no particular
behavior by which people actually manifest their consent to the social
contract, there is no act that people can be forced to perfom that will
manifest their joining the state.
In the end, what it is to force such people to join the state can be seen
by considering why it is necessary to do so. The fact that such people, as
intelligible beings, do not recognize the a priori practical necessity of the
state is irrelevant, since justice is concerned with only the external
relations among persons. The fact that such people, as sensible or physical
beings, do not obey the authority of the state, however, means that, were
they members of the state they would have been subjected to coercion, as
necessary, to maintain the condition of justice. Membership in the state
amounts to nothing more than being subject to the threat of coercion in
response to violations of the law. Kant’s claim, that people who do not
accept the authority of the state should be forced to join the state, really
amounts to the claim that, in accord with the hypothetical social contract
that they necessarily accept insofar as they are rational beings, they should
be treated as members of the state.
Kant on rebellion and resistance
Kant has argued from the fact that people have an innate right to external
freedom, and the fact that this freedom is not violated by the use of
coercion against someone who is violating the freedom of another, to the
fact that people can be treated as if they were parties to an original
contract by which they agreed to accept the authority of the state. The
idea of an original contract, however, not only explains the political
obligations of the members of a state, but also accounts for the limitations
that exist on the authority of the state:
[The original contract] is in fact only an idea of reason, which
nonetheless has undoubted practical reality; for it can oblige every
legislator to frame his laws in such a way that they could have been
produced by the united will of a whole nation…. This is the test of
the rightfulness of every public law. For if a law is such that a whole
people could not possibly agree to it…it is unjust; but if it is at least
possible that a people could agree to it, it is our duty to consider the law
as just, even if the people is at present in such a position or attitude of
mind that it would probably refuse its consent if it were consulted.
(“TP,” 79)
The idea of the original contract, to which all human beings, insofar as they
are rational, necessarily consent, includes restrictions on the possible
legislation of a legitimate state. Basically, legislation is legitimate if it would
be possible for the people to consent to it. The fact that the people would be
likely to choose not to consent to a given piece of legislation is not relevant
to its legitimacy, provided that it does not require the violation of a perfect
duty, and, thus, could at least possibly receive the people’s consent.
Accordingly, it would not be surprising if Kant went on to argue that
rebellion and resistance against a state whose laws are legitimate is
absolutely prohibited, but that it is permissible to rebel against a state that
passes unjust legislation, or at least to resist the specific unjust laws. Such
a position would be consistent with the fact that Kant, on certain grounds,
applauded the French Revolution. This line of reasoning is also supported
by a passage in which Kant implies that resistance to illegitimate
legislation, which requires the violation of a perfect duty, is permissible, or
even required: “When men command anything which is itself evil (directly
opposed to the law of morality) we dare not, and ought not, obey them.”15
Despite this apparent endorsement of resistance to unjust legislation,
however, Kant repeatedly states that rebellion against states that enact
unjust legislation, and resistance to illegitimate legislation, are both
absolutely prohibited. At first blush this is rather surprising. After all,
Kant’s interest in the state is grounded in his concern for the development
of morality, which fundamentally entails the autonomy of the individual,
and, yet, submission to an unjust state seems undeniably to entail the
violation of morality and the denial of individual autonomy. Nevertheless,
Kant’s arguments for the absolute prohibition against rebellion and
resistance are well grounded in his most fundamental concerns.
Kant’s absolute prohibition against rebellion and resistance, while
holding a theory of illegitimate legislation, is evident. He says that “the
people too have inalienable rights against the head of state, even if these
cannot be rights of coercion” (“TP,” 84). Kant both recognizes that there
are things beyond the legitimate authority of the state, and asserts that the
people cannot use coercion in response to such transgressions. The
absolute nature of this prohibition is stated unequivocally: “it is the
people’s duty to endure even the most intolerable abuse of supreme
authority” (MM, 86). Another passage both expresses this absolute
prohibition, and begins to reveal Kant’s justification for it:
It thus follows that all resistance against the supreme legislative
power, all incitements of the subjects to violent expressions of
discontent, all defiance which breaks out into rebellion, is the
greatest and most punishable crime in a commonwealth, for it
destroys its very foundations. This prohibition is absolute.
(“TP,” 81)
Kant not only thinks that the prohibition against rebellion and resistance
is absolute, but that it must be absolute, because rebellion and resistance
destroy the very foundations of a state. Even a state that is unjust must be
supported because the state is necessary for the realization of the innate
right to external freedom, and to rebel or resist any state is to act on a
maxim that makes all states insecure:
For such resistance would be dictated by a maxim which, if it
became general, would destroy the whole civil constitution and put
an end to the only state in which men can possess rights.
(“TP,” 81)
For such procedures, if made into a maxim, make all lawful
constitutions insecure and produce a state of complete lawlessness
(status naturalis) where all rights cease at least to be effectual.
(“TP,” 82)
In his political philosophy, Kant argues for the necessity and the
legitimacy of the state because, without a state, the rights that people
have under the innate right to external freedom cannot be secured, and
humanity will not progress toward the ultimate and final ends of nature.
Rebellion and resistance, however, entail the adoption of maxims that
make the state impossible, rights ineffectual, and the hope for human
progress vain. Thus, it is only if people live within secure states, that are
themselves members of a healthy federation of states, that humanity can
possibly progress toward the ultimate and final ends of nature, the
complete development of human culture and the attainment of moral
perfection.

7 The word that is here translated as “jurisprudence” is the same word as is
translated “doctrine of right,” but the former corresponds to colloquial English.
Furthermore, the root of this word, “Recht,” can be translated as either “right”
or “justice” depending on the context. Thus, the “Doctrine of Right,” Kant’s
theory of jurisprudence, is concerned with those duties that are duties of justice.

that much better sense can be made of Kant’s political philosophy on the
