 It is impossible to know where Simone de Beauvoir’s thinking would have gone had she been spared the cold, the hunger and the fear of living in Nazi occupied Paris. What we do know is that coming face to face with forces of injustice beyond her control, the questions of evil and the Other took on new urgency. Beauvoir speaks of the war as creating an existential rupture in time. She speaks of herself as having undergone a conversion. She can no longer afford the luxury of focusing on her own happiness and pleasure. The question of evil becomes a pressing concern. One cannot refuse to take a stand. One is either a collaborator or not. In writing The Ethics of Ambiguity, Beauvoir takes her stand. She identifies herself as an existentialist and identifies existentialism as the philosophy of our (her) times because it is the only philosophy that takes the question of evil seriously. It is the only philosophy prepared to counter Dostoevsky’s claim that without God everything is permissible. That we are alone in the world and that we exist without guarantees, are not, however, the only truths of the human condition. There is also the truth of our freedom and this truth, as detailed in The Ethics of Ambiguity, entails a logic of reciprocity and responsibility that contests the terrors of a world ruled only by the authority of power.
