I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice.

What everyone wants from life is continuous and genuine happiness.

As though God had turned away from the wise, and written his decrees, not in the mind of man but in the entrails of beasts, or left them to be proclaimed by the inspiration and instinct of fools, madmen, and birds. Such is the unreason to which terror can drive mankind!

He who wishes to revenge injuries by reciprocal hatred will live in misery. But he who endeavors to drive away hatred by means of love, fights with pleasure and confidence; he resists equally one or many men, and scarcely needs at all the help of fortune. Those whom he conquers yield joyfully

self-preservation is the primary and only foundation of virtue.

Big fish eat small fish with as much right as they have power.

None are more taken in by flattery than the proud, who wish to be the first and are not.
