This is the first English translation of all of Kant's writings on moral and political philosophy collected in a single volume. No other collection competes with the comprehensiveness of this one. The translation of the Metaphysics of Morals by Mary Gregor appears in a new edition to conform to the guidelines of the Cambridge Edition and to reflect some widely accepted textual emendations adopted in a recent German edition of that work. The volume has been furnished with a substantial editorial apparatus including translator's introductions an explanatory notes to each text by Mary Gregor, and a general introduction to Kant's moral and political philosophy by Allen Wood.
