In the postwar years Jean-Paul Sartre set himself the task of writing a book on ethics. His concern was to take up issues raised by his existentialist ontology and to resolve problems in his bleak account of the human situation in Being and Nothingness. I am searching, he said, for an ethics for the present time. For several years he prepared background notes, but then put the material aside as too abstract and idealistic, leaving it for publication after his death. Years later he returned to ethics, this time in the hope of developing an account related to the Critique of Dialectical Reason. But once again he left the inquiry incomplete. There was yet a third attempt towards the end of his life when Sartre was blind and weak, a poignant witness to his abiding interest in ethics. This took the form of interviews with Benny Levy, which appeared in a controversial publication just before his death. Sartre in Search of an Ethics is a study of each of these stages in his ethical quest, with a focus on the major themes of his existentialist and dialectical ethics in the context of some of his main philosophical and literary writings.
