Based on an international conference in Chicago commemorating the hundredth anniversary of Martin Heidegger's birth, this volume includes essays by many of the most distinguished interpreters of Heidegger's philosophy from North America, Europe, and Asia. Taking account of the numerous texts by Heidegger that have been published for the first time in the past decade, these essays discuss and extend Heidegger's thought as it bears on a broad range of fundamental philosophical questions.
