This volume of essays by internationally prominent scholars interprets the full range of Heidegger's thought and major critical interpretations of it. It explores such central themes as hermeneutics, facticity and Ereignis, conscience in Being and Time, freedom in the writings of his period of transition from fundamental ontology, and his mature criticisms of metaphysics and ontotheology. The volume also examines Heidegger's interpretations of other authors, the philosophers Aristotle, Kant and Nietzsche and the poets Rilke, Trakl and George. A final group of essays interprets the critical reception of Heidegger's thought, both in the analytic tradition (Ryle, Carnap, Rorty and Dreyfus) and in France (Derrida and Lévinas). This rich and wide-ranging collection will appeal to all who are interested in the themes, the development and the context of Heidegger's philosophical thought.
