Truth is not an object to be possessed; it is a living thing recognized, cultivated by the mind and heart.

One must know oneself. If this does not serve to discover truth, it at least serves as a rule of life, and there is nothing better.

Since we cannot know all there is to be known about anything, we ought to know a little about everything.

Venerable, because it has perfect knowledge of man; lovable because it promises the true good.

If we do not know ourselves to be full of pride, ambition, lust, weakness, misery, and injustice, we are indeed blind. And if, knowing this, we do not desire deliverance, what can we say of a man...?

To tell the truth is useful to those to whom it is spoken, but disadvantageous to those who tell it, because it makes them disliked.
