Blessedness is not the reward of virtue but virtue itself.

The mind can only imagine anything, or remember what is past, while the body endures.

He who has a true idea, knows at that same time that he has a true idea, nor can he doubt concerning the truth of the thing.

Many errors, of a truth, consist merely in the application of the wrong names of things.

All laws which can be violated without doing any one any injury are laughed at. Nay, so far are they from doing anything to control the desires and passions of menб that, on the contrary, they direct and incite men's thoughts the more toward those very objects, for we always strive toward what is forbidden and desire the things we are not allowed to have. And men of leisure are never deficient in the ingenuity needed to enable them to outwit laws framed to regulate things which cannot be entirely forbidden... He who tries to determine everything by law will foment crime rather than lessen it.

Indulge yourself in pleasures only in so far as they are necessary for the preservation of health.

. . . to know the order of nature, and regard the universe as orderly is the highest function of the mind.
