This article is meant to stage an encounter, a kind of rendezvous, between Emmanuel Levinas and Simone de Beauvoir regarding how alterity seems to enable an ethical relation for Levinas while closing one for Beauvoir. I will argue that Beauvoir's reading of Levinas on “the other” is not a charitable one, and the ethical ambivalence in Levinas's notion of alterity can motivate the praxis Beauvoir seeks for undoing social forms of oppression. I will start with Beauvoir's interpretation of alterity as “feminine otherness” in Levinas's ethics that, for her, originates in the violent perspective of male privilege. Then I will move to Levinas's response to this critique in a set of interviews with Philip Nemo, and to consideration of how a more charitable reading of alterity, understood as a sort of ambivalence in the structure of subjectivity, creates a close proximity between Levinas's and Beauvoir's ethics of action. I contend that both Beauvoir and Levinas respectively developed their ethics of action, either of ambiguity or of ambivalent alterity, in order to free thought from the absolute seriousness with which normative standards are held.
