Although Martin Heidegger is undeniably one of the most influential philosophers of the twentieth century, among the philosophers who study his work we find considerable disagreement over what might seem to be basic issues: why is Heidegger important? What did his work do? This volume is an explicit response to these differences, and is unique in bringing together representatives of many different approaches to Heidegger's philosophy. Topics covered include Heidegger's place in the 'history of being', Heidegger and ethics, Heidegger and theology, and Heidegger and Nazi concepts of race. More generally, the contributors also address their respective visions of the nature of philosophy and the presuppositions which guide their understanding of Heidegger.
