Some philosophers were in favour of equality for women, but not Plato and Aristotle. Contrary to them, the Stoic philosophers argued for the equality of the sexes. In their view, sexual inequality was contrary to the laws of nature. In doing so, they followed the Cynics, who argued that men and women should wear the same clothing and get the same kind of education. They also saw marriage as a moral companionship between equals rather than a biological or social necessity. The Cynics practiced these views in their lives as well as in their teachings. The Stoics adopted the views of the Cynics and added them to their own theories of human nature. They put their sexual egalitarianism on a strong footing.
