Human society is divided into two sexes: the male—rational, strong, endowed with the capacity for procreation, equipped with soul and fit to rule; the female—passionate and unable to control her appetites, weak, providing only low matter for the process of procreation, devoid of soul and designed to be ruled. And because this is so, the rule of some men over other men can be justified by ascribing to those men some of the same qualities ascribed to the female.
