This concise and accessible textbook examines German philosopher Martin Heidegger’s entire body of work through the lens of his first and best-known book, Being and Time. An influential, twentieth-century scholar, Heidegger is often studied by opposing his early and later works.  This insightful, new text guides students through Heidegger’s ideas without shying away from controversial issues and debates within the scholarship.  By unifying Being and Time with the rest of Heidegger’s work, this book addresses the evolution of his thought across his lifetime. The text features a glossary of Greek, Latin, and English terms and a guide for reading the book in conjunction with Heidegger’s writings.
