The categorical imperative (German: kategorischer Imperativ) is the central philosophical concept in the deontological moral philosophy of Immanuel Kant. Introduced in Kant's 1785 Grounding for the Metaphysics of Morals, it may be defined as a way of evaluating motivations for action.

According to Kant, human beings occupy a special place in creation, and morality can be summed up in an imperative, or ultimate commandment of reason, from which all duties and obligations derive. He defined an imperative as any proposition declaring a certain action (or inaction) to be necessary.

Hypothetical imperatives apply to someone who wishes to attain certain ends. For example:

  • if I wish to quench my thirst, I must drink something;
  • if I wish to acquire knowledge, I must learn.

A categorical imperative, on the other hand, denotes an absolute, unconditional requirement that must be obeyed in all circumstances and is justified as an end in itself. It is best known in its first formulation:

Act only according to that maxim whereby you can, at the same time, will that it should become a universal law.[1]

Kant expressed extreme dissatisfaction with the popular moral philosophy of his day, believing that it could never surpass the level of hypothetical imperatives: a utilitarian says that murder is wrong because it does not maximize good for those involved, but this is irrelevant to people who are concerned only with maximizing the positive outcome for themselves. Consequently, Kant argued, hypothetical moral systems cannot persuade moral action or be regarded as bases for moral judgments against others, because the imperatives on which they are based rely too heavily on subjective considerations. He presented a deontological moral system, based on the demands of the categorical imperative, as an alternative.

Nature of the concept[edit]

The capacity that underlies deciding what is moral is called pure practical reason, which is contrasted with pure reason (the capacity to know without having been shown) and mere practical reason (which allows us to interact with the world in experience). Hypothetical imperatives tell us which means best achieve our ends. They do not, however, tell us which ends we should choose. The typical dichotomy in choosing ends is between ends that are "right" (e.g., helping someone) and those that are "good" (e.g., enriching oneself). Kant considered the "right" superior to the "good"; to him, the "good" was morally irrelevant. In Kant's view, a person cannot decide whether conduct is "right," or moral, through empirical means. Such judgments must be reached a priori, using pure practical reason.[citation needed]

Reason, separate from all empirical experience, can determine the principle according to which all ends can be determined as moral. It is this fundamental principle of moral reason that is known as the categorical imperative. Pure practical reason is the process of determining what ought to be done without reference to empirical contingent factors. Moral questions are determined independent of reference to the particular subject posing them. It is because morality is determined by pure practical reason rather than particular empirical or sensuous factors that morality is universally valid. This moral universalism has come to be seen as the distinctive aspect of Kant's moral philosophy and has had wide social impact in the legal and political concepts of human rights and equality.[citation needed]

Freedom and autonomy[edit]

Kant viewed the human individual as a rationally self-conscious being with "impure" freedom of choice:

The faculty of desire in accordance with concepts, in-so-far as the ground determining it to action lies within itself and not in its object, is called a faculty to "do or to refrain from doing as one pleases". Insofar as it is joined with one's consciousness of the ability to bring about its object by one's action it is called choice (Willkür); if it is not joined with this consciousness its act is called a wish. The faculty of desire whose inner determining ground, hence even what pleases it, lies within the subject's reason is called the will (Wille). The will is therefore the faculty of desire considered not so much in relation to action (as choice is) but rather in relation to the ground determining choice in action. The will itself, strictly speaking, has no determining ground; insofar as it can determine choice, it is instead practical reason itself.

Insofar as reason can determine the faculty of desire as such, not only choice but also mere wish can be included under the will. That choice which can be determined by pure reason is called free choice. That which can be determined only by inclination (sensible impulse, stimulus) would be animal choice (arbitrium brutum). Human choice, however, is a choice that can indeed be affected but not determined by impulses, and is therefore of itself (apart from an acquired proficiency of reason) not pure but can still be determined to actions by pure will.

- Immanuel Kant, Metaphysics of Morals, 6:213-4

For a will to be considered "free", we must understand it as capable of affecting causal power without being caused to do so. But the idea of lawless free will, that is, a will acting without any causal structure, is incomprehensible. Therefore, a free will must be acting under laws that it gives to itself.

Although Kant conceded that there could be no conceivable example of free will, because any example would only show us a will as it appears to us — as a subject of natural laws — he nevertheless argued against determinism. He proposed that determinism is logically inconsistent: The determinist claims that because A caused B, and B caused C, that A is the true cause of C. Applied to a case of the human will, a determinist would argue that the will does not have causal power and that something outside the will causes the will to act as it does. But this argument merely assumes what it sets out to prove: viz. that the human will is part of the causal chain.

Secondly, Kant remarks that free will is inherently unknowable. Since even a free person could not possibly have knowledge of their own freedom, we cannot use our failure to find a proof for freedom as evidence for a lack of it. The observable world could never contain an example of freedom because it would never show us a will as it appears to itself, but only a will that is subject to natural laws imposed on it. But we do appear to ourselves as free. Therefore he argued for the idea of transcendental freedom — that is, freedom as a presupposition of the question "what ought I to do?" This is what gives us sufficient basis for ascribing moral responsibility: the rational and self-actualizing power of a person, which he calls moral autonomy: "the property the will has of being a law unto itself."

Good will, duty, and the categorical imperative[edit]

Since considerations of the physical details of actions are necessarily bound up with a person's subjective preferences, and could have been brought about without the action of a rational will, Kant concluded that the expected consequences of an act are themselves morally neutral, and therefore irrelevant to moral deliberation. The only objective basis for moral value would be the rationality of the good will, expressed in recognition of moral duty.

Duty is the necessity to act out of reverence for the moral law set by the categorical imperative. Only a categorical imperative, then, can be the supreme principle of morality.

The First Formulation[edit]

From this step, Kant concludes that a moral proposition that is true must be one that is not tied to any particular conditions, including the identity of the person making the moral deliberation. A moral maxim must imply absolute necessity, which is to say that it must be disconnected from the particular physical details surrounding the proposition, and could be applied to any rational being. This leads to the first formulation of the categorical imperative:

  • "Act only according to that maxim whereby you can at the same time will that it should become a universal law without contradiction."[1]

Kant divides the duties imposed by this formulation into two subsets:

Perfect duty[edit]

According to his reasoning, we first have a perfect duty not to act by maxims that result in logical contradictions when we attempt to universalize them. The moral proposition A: "It is permissible to steal" would result in a contradiction upon universalisation. The notion of stealing presupposes the existence of property, but were A universalized, then there could be no property, and so the proposition has logically negated itself.

In general, perfect duties are those that are blameworthy if not met, as they are a basic required duty for a human being.

Imperfect duty[edit]

Second, we have imperfect duties, which are still based on pure reason, but which allow for desires in how they are carried out in practice. Because these depend somewhat on the subjective preferences of humankind, this duty is not as strong as a perfect duty, but it is still morally binding. As such, unlike perfect duties, you do not attract blame should you not complete an imperfect duty but you shall receive praise for it should you complete it, as you have gone beyond the basic duties and taken duty upon yourself. Imperfect duties are circumstantial, meaning simply that you could not reasonably exist in a constant state of performing that duty. This is what truly differentiates between perfect and imperfect duties, because imperfect duties are those duties that are never truly completed. A particular example provided by Kant is the imperfect duty to cultivate one's own talents.[citation needed]

The Second Formulation[edit]

Every rational action must set before itself not only a principle, but also an end. Most ends are of a subjective kind, because they need only be pursued if they are in line with some particular hypothetical imperative that a person may choose to adopt. For an end to be objective, it would be necessary that we categorically pursue it.

The free will is the source of all rational action. But to treat it as a subjective end is to deny the possibility of freedom in general. Because the autonomous will is the one and only source of moral action, it would contradict the first formulation to claim that a person is merely a means to some other end, rather than always an end in themselves.

On this basis, Kant derives second formulation of the categorical imperative from the first.

By combining this formulation with the first, we learn that a person has perfect duty not to use the humanity of themselves or others merely as a means to some other end. As a slaveowner would be effectively asserting a moral right to own a person as a slave, they would be asserting a property right in another person. But this would violate the categorical imperative because it denies the basis for there to be free rational action at all; it denies the status of a person as an end in themselves. One cannot, on Kant's account, ever suppose a right to treat another person as a mere means to an end.

The second formulation also leads to the imperfect duty to further the ends of ourselves and others. If any person desires perfection in themselves or others, it would be their moral duty to seek that end for all people equally, so long as that end does not contradict perfect duty.

The Third Formulation[edit]

Because a truly autonomous will would not be subjugated to any interest, it would only be subject to those laws it makes for itself — but it must also regard those laws as if they would be bound to others, or they would not be universalizable, and hence they would not be laws of conduct at all. Thus Kant presents the notion of the hypothetical Kingdom of Ends of which he suggests all people should consider themselves both means and ends.

"Act in such a way that you treat humanity, whether in your own person or in that of another, always at the same time as an end and never merely as a means."[2] We ought to act only by maxims that would harmonize with a possible kingdom of ends. We have perfect duty not to act by maxims that create incoherent or impossible states of natural affairs when we attempt to universalize them, and we have imperfect duty not to act by maxims that lead to unstable or greatly undesirable states of affairs.

Normative interpretation[edit]

Although Kant was intensely critical of the use of examples as moral yardsticks, because they tend to rely on our moral intuitions (feelings) rather than our rational powers, this section will explore some interpretations of the categorical imperative for illustrative purposes.

Deception[edit]

Further information: Doctrine of mental reservation

Kant asserted that lying, or deception of any kind, would be forbidden under any interpretation and in any circumstance. In Grounding, Kant gives the example of a person who seeks to borrow money without intending to pay it back. This is a contradiction because if it were a universal action, no person would lend money anymore as he knows that he will never be paid back. The maxim of this action, says Kant, results in a contradiction in conceivability (and thus contradicts perfect duty). With lying, it would logically contradict the reliability of language. If it were universally acceptable to lie, then no one would believe anyone and all truths would be assumed to be lies. The right to deceive could also not be claimed because it would deny the status of the person deceived as an end in itself. The theft would be incompatible with a possible kingdom of ends. Therefore, Kant denied the right to lie or deceive for any reason, regardless of context or anticipated consequences.

Theft[edit]

Kant argued that any action taken against another person to which he or she could not possibly consent is a violation of perfect duty interpreted through the second formulation. If a thief were to steal a book from an unknowing victim, it may have been that the victim would have agreed, had the thief simply asked. However, no person can consent to theft, because the presence of consent would mean that the transfer was not a theft. Because the victim could not have consented to the action, it could not be instituted as a universal law of nature, and theft contradicts perfect duty.

Suicide[edit]

Kant applied his categorical imperative to the issue of suicide in Grounding for the Metaphysics of Morals,[3] writing that:

A man reduced to despair by a series of misfortunes feels sick of life, but is still so far in possession of his reason that he can ask himself whether taking his own life would not be contrary to his duty to himself. Now he asks whether the maxim of his action could become a universal law of nature. But his maxim is this: from self-love I make as my principle to shorten my life when its continued duration threatens more evil than it promises satisfaction. There only remains the question as to whether this principle of self-love can become a universal law of nature. One sees at once that a contradiction in a system of nature whose law would destroy life by means of the very same feeling that acts so as to stimulate the furtherance of life, and hence there could be no existence as a system of nature. Therefore, such a maxim cannot possibly hold as a universal law of nature and is, consequently, wholly opposed to the supreme principle of all duty.

— Immanuel Kant, Grounding for the Metaphysics of Morals, p30-31

Laziness[edit]

Kant also applies the categorical imperative in Grounding for the Metaphysics of Morals on the subject of "failing to cultivate one's talents." He proposes a man who if he cultivated his talents could bring many goods, but he has everything he wants and would prefer to enjoy the pleasures of life instead. The man asks himself how the universality of such a thing works. While Kant agrees that a society could subsist if everyone did nothing, he notes that the man would have no pleasures to enjoy, for if everyone let their talents go to waste, there would be no one to create luxuries that created this theoretical situation in the first place. Not only that, but cultivating one's talents is a duty to oneself. Thus, it is not willed to make laziness universal, and a rational being has imperfect duty to cultivate its talents. Kant concludes in Grounding:

...he cannot possibly will that this should become a universal law of nature or be implanted in us as such a law by a natural instinct. For as a rational being he necessarily wills that all his faculties should be developed, inasmuch as they are given him for all sorts of possible purposes.[4]

Charity[edit]

Kant's last application of the categorical imperative in Grounding for the Metaphysics of Morals is of charity. He proposes a fourth man who finds his own life fine but sees other people struggling with life and who ponders the outcome of doing nothing to help those in need (while not envying them or accepting anything from them). While Kant admits that humanity could subsist (and admits it could possibly perform better) if this were universal, he states in Grounding:

But even though it is possible that a universal law of nature could subsist in accordance with that maxim, still it is impossible to will that such a principle should hold everywhere as a law of nature. For a will that resolved in this way would contradict itself, inasmuch as cases might often arise in which one would have need of the love and sympathy of others and in which he would deprive himself, by such a law of nature springing from his own will, of all hope of the aid he wants for himself.[5]

Cruelty to animals[edit]

Kant derived a prohibition against cruelty to animals as a violation of a duty in relation to oneself. According to Kant, man has the imperfect duty to strengthen the feeling of compassion, since this feeling promotes morality in relation to other human beings. But, cruelty to animals deadens the feeling of compassion in man. Therefore, man is obliged not to treat animals brutally (Kant, Metaphysics of Morals, § 17).

Normative criticism[edit]

The Golden Rule[edit]

The first formulation of the Categorical Imperative appears similar to The Golden Rule.

The 'Golden Rule' (in its negative form) says: "Do not impose on others what you do not wish for yourself."[6]

The 'Golden Rule' (in its positive form) says: "Treat others how you wish to be treated".[7]

Kant's first formulation of CI says: "Act only in accordance with that maxim through which you can at the same time will that it become a universal law."

Due to this similarity, some have thought the two are identical.[8]

Peter Corning suggests that, "Kant's objection to the Golden Rule is especially suspect because the categorical imperative (CI) sounds a lot like a paraphrase, or perhaps a close cousin, of the same fundamental idea. In effect, it says that you should act toward others in ways that you would want everyone else to act toward others, yourself included (presumably). Calling it a universal law does not materially improve on the basic concept."[9] Corning claims that Ken Binmore thought so as well.

Kant himself did not think so in Grounding for the Metaphysics of Morals. Rather, the categorical imperative is an attempt to identify a purely formal and necessarily universally binding rule on all rational agents. The Golden Rule, on the other hand, is neither purely formal nor necessarily universally binding. It is "empirical" in the sense that applying it depends on providing content, like "If you don't want others to hit you, then don't hit them." Also, it is a hypothetical imperative in the sense that it can be formulated, "If you want X done to you, then do X to others." Kant feared that the hypothetical clause, "if you want X done to you," remains open to dispute.[10] He wanted an imperative that was categorical: "Do X to others." And this he thinks he discovered and formulated. Kant thought, therefore, that the Golden Rule (insofar as it is accurate) is derived from the categorical imperative .[11]

Inquiring murderer[edit]

One of the first major challenges to Kant's reasoning came from the French philosopher Benjamin Constant, who asserted that since truth telling must be universal, according to Kant's theories, one must (if asked) tell a known murderer the location of his prey. This challenge occurred while Kant was still alive, and his response was the essay On a Supposed Right to Tell Lies from Benevolent Motives (sometimes translated On a Supposed Right to Lie because of Philanthropic Concerns). In this reply, Kant agreed with Constant's inference, that from Kant's premises one must infer a moral duty not to lie to a murderer.

Kant denied that such an inference indicates any weakness in his premises: not lying to the murderer is required because moral actions do not derive their worth from the expected consequences. He claimed that because lying to the murderer would treat him as a mere means to another end, the lie denies the rationality of another person, and therefore denies the possibility of there being free rational action at all. This lie results in a contradiction in conceivably and therefore the lie is in conflict with duty.

Constant and Kant agree that refusing to answer the murderer's question is consistent with the categorical imperative, but assume for the purposes of argument that refusing to answer would not be an option, perhaps because of duress such as kidnapping, torture, or extortion. Neither of them explain why such duress would cause a truthful answer to be more consistent with the categorical imperative than refusing to answer. Subsequent commentators on the challenge often point out that there is likely no such reason.

Questioning autonomy[edit]

Schopenhauer's criticism of the Kantian philosophy expresses doubt concerning the absence of egoism in the Categorical Imperative. Schopenhauer claimed that the Categorical Imperative is actually hypothetical and egotistical, not categorical. Kierkegaard believed Kantian autonomy was insufficient and that, if unchecked, people tend to be lenient in their own case, either by not exercising the full rigor of the moral law or by not properly disciplining themselves of moral transgressions:

Kant was of the opinion that man is his own law (autonomy) - that is, he binds himself under the law which he himself gives himself. Actually, in a profounder sense, this is how lawlessness or experimentation are established. This is not being rigorously earnest any more than Sancho Panza's self-administered blows to his own bottom were vigorous. ... Now if a man is never even once willing in his lifetime to act so decisively that [a lawgiver] can get hold of him, well, then it happens, then the man is allowed to live on in self-complacent illusion and make-believe and experimentation, but this also means: utterly without grace.

Papers and Journals

Kant's categorical imperative and the trial of Adolf Eichmann[edit]

In 1961, discussion of Kant's categorical imperative included even the trial of the infamous SS Lieutenant Colonel Adolf Eichmann in Jerusalem.

As Hannah Arendt wrote in her book on the trial, Eichmann declared "with great emphasis that he had lived his whole life ... according to a Kantian definition of duty". Arendt considered this so "incomprehensible on the face of it" that it confirmed her sense that he wasn't really thinking at all, just mouthing accepted formulae, thereby establishing his banality.[12] Judge Raveh indeed had asked Eichmann whether he thought he had really lived according to the categorical imperative during the war. Eichmann acknowledged he did not "live entirely according to it, although I would like to do so." [12]

Deborah Lipstadt, in her book on the trial, takes this as evidence that evil is not banal, but is in fact self-aware.
