Frases do grande gênio Leonardo Da Vinci:"The potencies are four: memory and intellect, appetite and concupiscence. The two are of the reason, the others of the senses."
"Ask advise of him who governs himself well."
"If you governed your body by the rules of virtue you would have no desire in this world."
