What knowledge is there of which man is capable that is not founded on the exterior,--the relation that exists between visible and invisible, the perceptible and the imperceptible?

He who reforms himself has done more towards reforming the public than a crowd or noisy, impotent patriots.

Airs of importance are the credentials of impotence.

His calumny is not only the greatest benefit a rogue can confer on us, but the only service he will perform for nothing.

He who goes round about in his requests wants commonly more than he chooses to appear to want.

He surely is most in need of another's patience, who has none of his own.

Be not the fourth friend of him who had three before and lost them.
