This book reconstructs the intense early post-Kantian debate on freedom of the will, choice, and moral imputability for the first time. It addresses the following questions: How is freedom of choice possible given the causal predetermination of the world? How can we escape skepticism about freedom of the will? What are the characteristics of moral freedom? Are we free to act immorally, and if so, how exactly? And finally: How can we conceive of our individual freedom as being compatible with nature and society?
