 Some have argued that the belated admission of Beauvoir into the ranks of philosophers is a matter of sexism on two counts. The first concerns the fact that Beauvoir was a woman. Her philosophical writings were read as echoes of Sartre rather than explored for their own contributions because it was only “natural” to think of a woman as a disciple of her male companion. The second concerns the fact that she wrote about women. The Second Sex, recognized as one of the hundred most important works of the twentieth century, would not be counted as philosophy because it dealt with sex, hardly a burning philosophical issue (so it was said). This encyclopedia entry shows how much things have changed. Long overdue, Beauvoir’s recognition as a philosopher is now secure.
