He has managed to satisfy this need in various ways - through myths, through dance and song, through systems of philosophy and through the order that he has imposed upon the visible world.

Those who wish, in the interest of morality, to reduce Leonardo, that inexhaustible source of creative power, to a neutral or sexless agency, have a strange idea of doing service to his reputation.
