Beginner's Guide to Kant's Moral Philosophy

Kant’s moral philosophy centers on the "goodwill"—the internal intention to do the right thing—as the only thing that is good without qualification. Morality is not defined by the consequences of an action, such as a bartender giving correct change to ensure repeat business, but by whether the action is motivated by a pure respect for moral rules. These rules are grounded in logic and apply to all rational beings, forming the Categorical Imperative: one should only act on maxims that can be consistently willed as universal laws. This framework requires treating humanity as an end in itself rather than a mere means and viewing oneself as a legislator of universal behavior. Ultimately, moral authority is self-imposed through reason, necessitating the existence of free will to allow individuals to consciously place these logical restrictions upon their own desires.
