Groundwork of the Metaphysics of Morals

Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words its aim is to search for and establish the supreme principle of morality, the categorical imperative. The centerpiece of the Groundwork is Kant's most famous proposition, the Categorical Imperative. While this is often equated with the Golden Rule (do unto others as you would have them do unto you), the Categorical Imperative argues for a more universal set of moral action - for example, if one does not mind being lied to, then lying does not become a problem, according to the Golden Rule, but for Kant, this would be unacceptable as it is a violation of the rational principles of what morals are. Kant proceeds to look at issues of law, duty, free will and the good will, and autonomy of action. Kant argues strongly for the need for philosophy to guard against whim, taste and personal desire from becoming normative agents in the way we construct the moral universe. He argue for objective principles to govern the will, and categorizes these as either hypothetical or categorical. Kant also discusses the formulation of universal law and the way in which rational agents should formulate and view this kind of law.
