“Quality is not an act, it is a habit.”

“We acquire a particular quality by acting in a particular way.”

“Happiness does not lie in amusement; it would be strange if one were to take trouble and suffer hardship all one's life in order to amuse oneself”

“The female is, as it were, a mutilated male, and the catamenia are semen, only not pure; for there is only one thing they have not in them, the principle of soul.”
