What to read after Groundwork for the Metaphysics of Morals?

Now in a new, affordable edition with updated notes, a superbly readable translation of Kant’s classic work

This work, one of the most important texts in the history of ethics, presents Immanuel Kant’s conception of moral self-government based on pure reason. It has been a source of controversy and an object of reinterpretation for over two centuries. This new edition of Kant’s work provides a fresh translation that is uniquely faithful to the German original and more fully annotated than any previous translation. The editor and translator, Allen Wood, has written a new introduction.
