Richard Polt provides a lively and accessible introduction to one of the most influential and intellectually demanding philosophers of the modern era. Covering the entire range of Heidegger's thought, Polt skillfully communicates the essence of the philosopher, enabling readers, especially those new to his writings, to approach his works with confidence and insight. Polt presents the questions Heidegger grappled with and the positions he adopted, and also analyzes persistent points of difference between competing schools of interpretation. The book begins by exploring Heidegger's central concern, the question of Being, and his way of doing philosophy. After considering his environment, personality, and early thought, it carefully takes readers through his best-known work, Being and Time. Heidegger concludes with highlights of its subject's later thought, providing guidelines for understanding Contributions to Philosophy and other important texts. It gives special attention to the philosopher's political involvement with the Nazis in the 1930s, indicating the strengths and weaknesses of the reactions to his politics, reactions ranging from exculpation to complete condemnation.
