This is the first English translation of the seminar Martin Heidegger gave during the Winter of 1934-35, which dealt with Hegel's Philosophy of Right. This remarkable text is the only one in which Heidegger interprets Hegel's masterpiece in the tradition of Continental political philosophy while offering a glimpse into Heidegger's own political thought following his engagement with Nazism. It also confronts the ideas of Carl Schmitt, allowing readers to reconstruct the relation between politics and ontology. The book is enriched by a collection of interpretations of the seminar, written by select European and North American political thinkers and philosophers. Their essays aim to make the seminar accessible to students of political theory and philosophy, as well as to open new directions for debating the relation between the two disciplines. A unique contribution, this volume makes available key lectures by Heidegger that will interest a wide readership of students and scholars.
