Sam, a student in my Feminist Theory course, points out that the percentage of people with full-time teaching jobs who are women is about 17% and that the percentage of people in Congress who are women is also about 17%.
No claim about magic numbers here, but just an interesting mirroring.
17% of U.S. Senators are women.
16.6% of the members of the U.S. House of Representatives are women.
In both cases, there is nothing about the work that's done that would predispose women to have less ability or experience than men. (Indeed, in both cases isn't the work related to universals? That is, in the political body, a single representative stands for all constituents, and in philosophy, the philosopher identifies universal truths.) Also in both cases, the methods involve adversarial discussion, and the field's history is predominately male and symbolically masculine.
