Groundwork of The Metaphysic of Morals

Groundwork Of The Metaphysic Of Morals

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.

The Groundwork is notable for its explanation of the categorical imperative, which is the central concept of Kant’s moral philosophy.

The Groundwork is broken into a preface, followed by three sections. Kant's argument works from common reason up to the supreme unconditional law, in order to identify its existence. He then works backwards from there to prove the relevance and weight of the moral law. The third and final section of the book is famously obscure, and it is partly because of this that Kant later, in 1788, decided to publish the Critique of Practical Reason.
