The conscience is more wise than science.

Learn the value of a man's words and expressions, and you know him. Each man has a measure of his own for everything; this he offers you inadvertently in his words. He who has a superlative for everything wants a measure for the great or small.

Be certain that he who has betrayed thee once will betray thee again.

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 can feel no little wants who is in pursuit of grandeur.

I am prejudiced in favor of him who, without impudence, can ask boldly. He has faith in humanity, and faith in himself. No one who is not accustomed to giving grandly can ask nobly and with boldness.

There are three classes of men; the retrograde, the stationary and the progressive.
