Though it has gone unnoticed so far in Beauvoir Studies, the term “singularity” is a technical one for Simone de Beauvoir. In the first half of the essay I discuss two reasons why this term has been obscured. First, as is well known Beauvoir has not been read in the context of the history of philosophy until recently. Second, in The Ethics of Ambiguity at least, singularité is translated both inconsistently and quite misleadingly. In the second half of the essay (...) I attempt to demonstrate the importance of this term in The Ethics. The will to disclose being is the will to disclose the singularity of the other, whether human, land, sky or painting. Ambiguity, which Beauvoir distinguishes from absurdity in Camus, is an image suggesting this necessarily mutual disclosure of singularity. (shrink)
