Martin Heidegger (1889-1976) is regarded as one of the twentieth century's most important philosophers. Ted Sadler was formerly Lecturer in Philosophy at the University of Sydney, Australia.

"It would be difficult to overestimate the importance of these lecture courses for an understanding of the development of Heidegger's thinking; yet in the very act of illuminating this development, they also throw new light on many of the most fundamental ideas figuring in 'Being and Time' itself. This book will be essential reading for anyone looking for the argumentation behind Heidegger's unique conception of human existence." Ian Lyne, University of Durham"
