Tao Te Ching

“in those thousand times a thousand years, man had to be pugnacious, always ready to fight—for his food, for his mate, for his life. If he could, he took more mates than one, for hunting and fighting were mortally dangerous and left a surplus of women over men; so the male is still polygamous [or polygamous] by nature.”
