Categorical imperative

Lore & Background

The categorical imperative commands immediately the maxims one conceives which match its categorical requirements, denoting an absolute, unconditional requirement that must be obeyed in all circumstances and is justified as an end in itself, possessing intrinsic value beyond simply being desirable. Kant expressed strong dissatisfaction with the popular moral philosophy of his day, believing that it could never surpass the merely conditional command of hypothetical imperatives. He argued that hypothetical moral systems cannot determine moral action or be regarded as bases for legitimate 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. Kant viewed the human individual as a rationally self-conscious being with 'impure' freedom of choice. For a will to be considered free, we must understand it as capable of affecting causal power without being caused to do so. A free will must be acting under laws that it gives to itself. Kant argued for the idea of transcendental freedom—freedom as a presupposition of the question 'what ought I to do?'—which gives sufficient basis for ascribing moral responsibility: the rational and self-actualizing power of a person, which he calls moral autonomy.

Reader's Guide

The categorical imperative represents Kant's attempt to ground morality in reason alone, independent of empirical experience or subjective desires. Its significance lies in establishing a deontological ethical system where actions are judged moral based on their adherence to universalizable maxims rather than their consequences. This approach directly challenged utilitarian and other hypothetical moral systems that Kant believed could never produce legitimate moral judgments because they relied on subjective considerations. The distinction that each action must not be empirically determined by observable experience has had wide social impact in the legal and political concepts of human rights and equality. Kant's first formulation—the principle of universalizability—requires that one act only according to maxims that could become universal law without contradiction. This leads to a division of duties into perfect duties (which cannot be universalized without logical contradiction) and imperfect duties. The categorical imperative's legacy endures in contemporary moral philosophy, where it continues to inform debates about moral obligation, human dignity, and the foundations of ethical reasoning.
