In 1943, Jean-Paul Sartre published his masterpiece, Being and Nothingness , and laid the foundation of his legacy as one of the greatest twentieth century philosophers. A brilliant and radical account of the human condition, Being and Nothingness explores what gives our lives significance. In a new and more accessible translation, this foundational text argues that we alone create our values and our existence is characterized by freedom and the inescapability of choice. Far from being an internal, passive container for our thoughts and experiences, human consciousness is constantly projecting itself into the outside world and imbuing it with meaning. Now with a new foreword by Harvard professor of philosophy Richard Moran, this clear-eyed translation guarantees that the groundbreaking ideas that Sartre introduced in this resonant work will continue to inspire for generations to come.
