I'm a female philosophy student, and I had an argument with my sister about the lack of female philosophers taught in college classes. She claimed that this was because of current sexism in the field of philosophy -- the mostly male philosophy professors disregard many great female philosophers and don't teach them. I thought that it was just a product of past sexism -- there historically haven't been many women in the field of philosophy, and therefore very few great female philosophers. Who's right? And if there aren't great female philosophers, should texts by women be taught anyway, as a kind of affirmative action?
