There is a foolish corner in the brain of the wisest man.

A tyrant must put on the appearance of uncommon devotion to religion. Subjects are less apprehensive of illegal treatment from a ruler whom they consider god-fearing and pious. On the other hand, they do less easily move against him, believing that he has the gods on his side.

Happiness is a kind of activity of the soul; whereas the remaining good things are either merely indispensable conditions of happiness, or are of the nature of auxiliary means, and useful instrumentally.

Nobody will be afraid who believes nothing can happen to him.

A whole is that which has beginning middle and end.

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.

Bad people...are in conflict with themselves; they desire one thing and will another, like the incontinent who choose harmful pleasures instead of what they themselves believe to be good.
