This international collaborative project on G. W. F. Hegel’s philosophy includes contributions by eighteen scholars of 18th to 20th century philosophy. It will be an essential reference tool for students and scholars of modern philosophic thought in general and of 19th century German thought in particular. The first part of the volume examines Hegel’s early writings up to and including the 1807 Phenomenology of Spirit. The second part is devoted to Hegel’s major mature works and lectures as well as to the primary themes of his system of philosophy. It opens with a comprehensive account of Hegel’s Science of Logic followed by detailed treatments of the Philosophy of Nature and the Philosophy of Spirit from the Encyclopaedia of Philosophical Sciences. Three further parts of this volume investigate key concepts and interpretive issues, paradigmatic forms of Hegelian argumentation, and main lines of Hegel’s influence since the mid-19th century. The volume contains chronologies of Hegel’s life and works, a bibliography of primary and secondary sources and an analytical index.
