The Groundwork of the Metaphysic(s) of Morals (German: Grundlegung zur Metaphysik der Sitten, 1785), also known as Foundations of the Metaphysics of Morals, Grounding of the Metaphysics of Morals, and Grounding for the Metaphysics of Morals, is Immanuel Kant`s first contribution to moral philosophy. It argues for an a priori basis for morality. Where the Critique of Pure Reason laid out Kant`s metaphysical and epistemological ideas, this relatively short, primarily meta-ethical, work was intended to outline and define the concepts and arguments shaping his future work The Metaphysics of Morals.
