Karl Ameriks here collects his most important essays to provide a uniquely detailed and up-to-date analysis of Kant's main arguments in all three major areas of his work: theoretical philosophy ( ), practical philosophy ( ), and aesthetics ( ). Guiding the volume is Ameriks's belief that one cannot properly understand any one of these except in the context of the other two. The essays can be read individually, but read together they offer a comprehensive guide to the main themes of the most influential of all modern philosophical systems.
