Immanuel Kant is widely considered to be the most important and influential thinker of modern Europe and the late Enlightenment. His philosophy is extraordinarily wide-ranging and his influence has been pervasive throughout eighteenth, nineteenth and twentieth-century thought, in particular in the work of the German Idealists, and also in both Analytic and Continental philosophy today. This comprehensive and accessible companion to Kant's historical and philosophical context, philosophical concerns, major works and enduring influence features more than 100 specially commissioned entries, written by a team of experts in the field, covering every aspect of his philosophy. The Companion presents a comprehensive overview of the historical and philosophical context in which Kant wrote and the various features, themes and topics apparent in his thought. It also includes extensive synopses of all his major published works and a survey of the key lines of reception and influence. It concludes with a thoroughly comprehensive bibliography of English language secondary literature. This is an essential reference tool for anyone working in the field of eighteenth-century German philosophy.
