Fundamental Principles Of The Metaphysic Of Morals

Kant establishes a pure moral philosophy, arguing that the only thing good without qualification is a "good will." He develops the concept of the Categorical Imperative, a rule requiring that one's actions must be suitable to become a universal law for everyone. The text strips away empirical motives like happiness or desire, focusing strictly on the rational necessity of duty. It is a rigorous defense of objective morality based on the structure of reason itself.
