The supreme principle is the categorical imperative, which commands unconditionally: act only on that maxim by which you can at the same time will it become a universal law; treat humanity always at the same time as an end and never merely as a means; act as a legislating member of a kingdom of ends. The three formulations are equivalent. The will that gives itself the moral law is autonomous; the will that takes its law from outside is heteronomous, and heteronomy can never ground unconditional obligation. Moral worth attaches to acting from duty, not merely in conformity with duty: the shopkeeper who is honest because honesty pays, and the philanthropist who helps from sympathetic inclination, have no moral worth, however good their actions appear. Consequences are contingent and cannot ground unconditional moral demands.","paragraphs":[[{"t":"Morality must be grounded *a priori*, in pure practical reason, not in any empirical motive — happiness, sympathy, sentiment, or consequence.","n":[]},{"t":"The supreme principle is the categorical imperative, which commands unconditionally: act only on that maxim by which you can at the same time will it become a universal law; treat humanity always at the same time as an end and never merely as a means; act as a legislating member of a kingdom of ends.","n":[]}],[{"t":"The three formulations are equivalent.","n":[]},{"t":"The will that gives itself the moral law is autonomous; the will that takes its law from outside is heteronomous, and heteronomy can never ground unconditional obligation.","n":[1]},{"t":"Moral worth attaches to acting from duty, not merely in conformity with duty: the shopkeeper who is honest because honesty pays, and the philanthropist who helps from sympathetic inclination, have no moral worth, however good their actions appear.","n":[2]},{"t":"Consequences are contingent and cannot ground unconditional moral demands.","n":[]}]],"texts":"Groundwork of the Metaphysics of Morals (1785), Sections II and III; Critique of Practical Reason (1788), the Analytic and the Fact of Reason argument; Metaphysics of Morals (1797), the Doctrine of Virtue.

The utilitarian alternative (Bentham, Mill) treats Kantian deontology as rule-worship that produces monstrous counterexamples. Twentieth- and twenty-first-century Kantians (Korsgaard, O'Neill, Rawls, Habermas) defend the imperative in updated form, generally by anchoring it in the constitutive structure of agency or rational discourse. Bernard Williams's critique of \"the morality system\" is the most sustained recent challenge from outside the Kantian tradition.","era":"1724-1804","discipline":"Philosophy","refs":[{"n":1,"work":"Groundwork of The metaphysics of morals (1785)","page":"pp. 123–124","canonical":"Ak. 4:439–4:441","quote":"An action that can coexist with the autonomy of the will is *permitted;* one that does not accord with it is *forbidden.* A will whose maxims necessarily harmonize with the laws of autonomy is a *holy,* absolutely good will.
