"I^Kant on Freedom, Law, and Happiness is a well-researched and well-argued contribution to Kantian studies.I^Kant on Freedom, Law, and Happiness is an important book in Kantian studies that advances a unifying vision of Kant's practical philosophy. The change of view that Guyer advocates is welcome and reveals a side of Kant that has perhaps been veiled for too long. Although the book will undoubtedly be of interest to anyone studying Kant's practical philosophy in a scholarly manner, it may also be of interest to the general reader of philosophy who is prepared to approach the book with the patience and tenacity that Guyer's extended arguments often demand. In either case readers will be rewarded for their efforts with a deeper understanding of both Kant and of central philosophical issues related to freedom, happiness and morality." --Metapsychology Online Review
