I know that it is likely that as worship of the gods declines, faith between men and all human society will disappear, as well as that most excellent of all virtues, which is justice.

Anyone may fairly seek his own advantage, but no one has a right to do so at another's expense.

Rather leave the crime of the guilty unpunished than condemn the innocent.

Friendship is nothing else than an accord in all things, human and divine, conjoined with mutual goodwill and affection.

Man is his own worst enemy.

It is virtue itself that produces and sustains friendship, not without virtue can friendship by any possibility exist.

Not to know what has been transacted in former times is to continue always a child.
