Published in English for the first time, Kant's Critique of Practical Reason is a slightly abridged and updated edition of Professor Hoeffe's groundbreaking work 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 and which are still relevant today: Enlightenment, critique, morality and cosmopolitanism. The second part demonstrates the extent to which Kant revolutionised moral philosophy. 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.
