Problem: Immanuel Kant (1724-1804) argued that the supreme principle of morality is a principle of practical rationality that he dubbed the "Categorical Imperative". Kant agreed with many of his predecessors that an analysis of practical reason reveals the requirement that rational agents must conform to instrumental principles. Yet he also argued that conformity to the CI (a non-instrumental principle), and hence to moral requirements themselves, can nevertheless be shown to be essential to rational agency. Thus, at the heart of Kant's moral philosophy is a conception of reason whose reach in practical affairs goes well beyond that of a Humean [see David Hume] 'slave' to the passions. Kant's most influential positions in moral philosophy are found in The Groundwork of the Metaphysics of Morals. What is an imperative, in Kant's philosophy? What is the difference between hypothetical and categorical imperatives? Into which category does he think moral demands fall, and why? Need Assignment Help?
