This book examines the concepts of subjectivity and selfhood developed in the oeuvre of Jean-Paul Sartre. Although Sartre is a prominent philosopher, the reception of his work is shrouded in misguided ideas concerning his alleged subjectivism. This book accurately positions Sartre in debates concerning the two themes which form a guiding thread throughout his work and remain immensely relevant in the philosophical landscape of today. Gusman expertly tracks and uncovers the nuances of the evolving notions of subjectivity and selfhood, paying particular attention to his claim that the Self is a ‘thing among things’ and to his views on narrative identity. Using as a framework the critical reception from thinkers in Sartre own tradition, the book also draws from the recent popularity of his thought in analytic philosophy of mind. Illuminating and impactful, this book provides an invaluable resource to scholars looking for a contemporary and up-to-date critical study of Sartre work.
