Playwright, novelist, political theorist, literary critic and philosopher, Jean-Paul Sartre (1905-80) remains an iconic figure. This book examines his philosophical ideas and methods. It is an introductory guide for the student who wishes to understand Sartre's philosophical argumentation. It reconstructs in plain language key instances of Sartre's philosophical reasoning at work and shows how certain questions arise for Sartre and what philosophical tools he uses to address those questions. Each chapter considers a range of issues in the Sartrean corpus including his conception of phenomenology, the question of self-identity, the Sartrean view of conscious beings, his understanding of the self, his theory of value, human action as both the originator and the outcome of social processes, dialectical reason, and his conception of artistic activity. Anthony Hatzimoysis is Lecturer in Philosophy at the University of Manchester.
