"Why is my pain perpetual, and my wound incurable, which refuseth to be healed?" -Jeremiah "Existentialism" today refers to faddism, decadentism, morbidity, the "philosophy of the graveyard"; to words like fear, dread, anxiety, anguish, suffering, aloneness, death; to novelists such as Jean-Paul Sartre, Dostoievski, Camus, Kafka; to philosophers like Kierkegaard, Heidegger, Marcel, Jaspers, and Sartre-and because it refers to, and is concerned with, all of these ideas and persons, existentialism has lost any clearer meaning it may have originally possessed. Because it has so many definitions, it can no longer be defined. As Sartre writes: "Most people who use the word existentialism would be em barrased if they had to explain it, since, now that the word is all the rage, even the work of a musician or painter is being called existentialist. A gossip columnist . . . signs himself The Exis tentialist, so that by this time the word has been so stretched and has taken on so broad a meaning, that it no longer means anything at all. " 2 This state of definitional confusion is not an accidental or negligible matter. An attempt will be made in this introduction to account for the confustion and to show why any definition of existentialism in volves us in a tangle. First, however, it is necessary to state in a tenta tive and very general manner what points of view are here intended when reference is made to existentialism.

Most readers of Sartre focus only on the works written at the peak of his influence as a public intellectual in the 1940s, notably "Being and Nothingness". "Jean-Paul Sartre: Key Concepts" aims to reassess Sartre and to introduce readers to the full breadth of his philosophy. Bringing together leading international scholars, the book examines concepts from across Sartre's career, from his initial views on the "inner life" of conscious experience, to his later conceptions of hope as the binding agent for a common humanity. The book will be invaluable to readers looking for a comprehensive assessment of Sartre's thinking - from his early influences to the development of his key concepts, to his legacy.

Sartre explains the theory of existential psychoanalysis in this treatise on human reality.

Sartre scholars and others engage with Jean-Paul Sartre's descriptions of the human body, bringing him into dialogue with feminists, sociologists, psychologists and historians and asking: What is pain? Do men and women experience their bodies differently? How do society and culture shape our bodies? Can we re-shape them?
