Kant's Groundwork of the Metaphysics of Morals

The greatest of all modern philosophers was born in the Baltic seaport of Konigsberg, East Prussia, the son of a saddler and never left the vicinity of his remote birthplace. Through his family pastor, Immanuel Kant received the opportunity to study at the newly founded Collegium Fredericianum, proceeding to the University of Konigsberg, where he was introduced to Wolffian philosophy and modern natural science by the philosopher Martin Knutzen. From 1746 to 1755, he served as tutor in various households near Konigsberg.

The early reviews were hostile and uncomprehending, and Kant's attempt to make his theories more accessible in his Prolegomena to Any Future Metaphysics (1783) was largely unsuccessful. Then, partly through the influence of former student J. G.

The following year Kant published a new, extensively revised edition of the Critique, following it up with the Critique of Practical Reason (1788), treating the foundations of moral philosophy, and the Critique of Judgment (1790), an examination of a
