An updated edition of Otfried Höffe's revolutionary study of Kant's philosophy. Published in English for the first time, Kant's Critique of Practical Reason is an abridged and updated edition of Otfried Höffe's groundbreaking work which was originally published in German. In the book, the author systematically introduces one of the most important areas of Kant's philosophy and relates its basic ideas to the debates of today. The first part introduces the four driving forces that motivated Kant's practical philosophy: enlightenment, critique, morality, and cosmopolitanism. The second part demonstrates the extent to which Kant revolutionized moral philosophy, and in the third part, the author explains the provocations that lie at the heart of Kant's practical philosophy. The remaining parts deal with political philosophy, the philosophy of history, and Kant's thinking about religion and education.
