Although they were not written by Kant himself, the transcripts of his lectures constitute an important source for philosophical research today. Some of the contributions presented in this volume discuss the authenticity and significance of these transcripts, for example the status of Kant's lectures on logic and anthropology, while others shed light on the historical formation of specific writings, for instance the texts on the philosophy of religion. The contributions provide new insights into Kant's philosophy, that, if looking at Kant's published writings alone, we would not be able to gain. In a number of cases, a critical analysis of Kant's lectures gives us a better understanding of his published works. Thus his lectures on metaphysics shed new light on his Critique of Pure Reason, while the lecture on natural law is a valuable source for the understanding of his published legal writings.
