Categorical Imperative


The categorical imperative (German: kategorischer Imperativ) is the central philosophical concept in the deontological moral philosophy of Immanuel Kant. Introduced in Kant's 1785 Groundwork of 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:

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:

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.

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.
