Summary:

'Kant's Moral World' offers a detailed defense of Immanuel Kant's practical metaphysics. While Kant is widely recognized for his moral philosophy, this study reveals how his ethical framework also serves as a foundation for answering some of the most profound metaphysical questions: Are we truly free? Do we have immortal souls? Can we rationally believe in God?
