KellyAnne, the same Rousseau wrote "Woman is made to submit to man and to endure even injustice at his hands" (L'Emile). And the same Schopenhauer (supposedly inspired by Rousseau) wrote "They form the sexus sequior, the second sex, inferior in every respect to the first." (On women). Schopenhauer absolutely loathed women (and his mother above all). I am afraid I can't seriously recognize them any credibility or authority over that particular subject.

I'm still curious about the explanation for biology-originated behaviors.
