Translated here for the first time into English, this text furnishes a new window into the final phase of Fichte's career. Delivered in the summer of 1812 at the newly founded University of Berlin, Fichte's lectures on ethics explore some of the key concepts and issues in his evolving system of radical idealism. Addressing moral theory, the theory of education, the philosophy of history, and the philosophy of religion, Fichte engages both directly and indirectly with some of his most important contemporaries and philosophical rivals, including Kant, Schelling, and Hegel. Benjamin D. Crowe's translation includes extensive annotations and a German-English glossary. His introduction situates the text systematically, historically, and institutionally within an era of cultural ferment and intellectual experimentation, and includes a bibliography of recent scholarship on Fichte's moral theory and on the final period of his career.
