The Ethics of Ambiguity. (Serie)

From Wikipedia -- The Ethics Of Ambiguity is Simone de Beauvoir's second major non-fiction work. It was prompted by a lecture she gave in 1945,[which?] after which she claimed that it was impossible to base an ethical system on her partner Jean-Paul Sartre's major philosophical work Being and Nothingness (French title: L'Être et le néant). The following year, over a six-month period, she took on the challenge, publishing the resulting text first as installments in Les Temps modernes and then, in November 1947, as a book.
