What follows are quotes from some of the greatest human minds to ever live. Why did they all come to similarly unfortunate conclusions in regard to women?

"From the beginning, nothing has been more alien, repugnant, and hostile to woman than truth—her great art is the lie, her highest concern is mere appearance and beauty. "

Nietzsche

"Women are directly adapted to act as the nurses and educators of our early childhood, for the simple reason that they themselves are childish, foolish, and short-sighted—in a word, are big children all their lives."

Schopenhauer

"Woman may be said to be an inferior man."

Aristotle

Why would such incisive, genius men, separated by generations, come to the same broad conclusions about women?
