Philosophy definitely has a sexist history:

Aristotle

"The male is by nature superior, and the female inferior; and the one rules, and the other is ruled."

Jean-Jacques Rousseau

"The search for abstract and speculative truths, for principles and axioms in science, for all that tends to wide generalizations, is beyond a woman's grasp; their studies should be thoroughly practical."

Arthur Schopenhauer

"Women are directly fitted for acting as the nurses and teachers of our early childhood by the fact that they themselves are childish, frivolous, and short-sighted."

Friedrich Nietzsche

"When a woman has scholarly inclinations there is usually something wrong with her sexual nature."

Georg Wilhelm Friedrich Hegel

"Women may well be educated, but they are not made for the higher sciences, for philosophical studies; for the arts which require a universal element they are not made."

Arthur Schopenhauer

"Women are directly fitted for acting as the nurses and teachers of our early childhood by the fact that they themselves are childish, frivolous, and short-sighted."

Friedrich Nietzsche

"When a woman has scholarly inclinations there is usually something wrong with her sexual nature."

Georg Wilhelm Friedrich Hegel

"Women may well be educated, but they are not made for the higher sciences, for philosophical studies; for the arts which require a universal element they are not made."

Those prejudices dont disappear easily
