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

He, who cannot forgive a trespass of malice to his enemy, has never yet tasted the most sublime enjoyment of love.

Avoid him who from mere curiosity asks three questions running about a thing that cannot interest Him.

Thinkers are scarce as gold; but he whose thoughts embrace all his subject, and who pursues it uninterruptedly and fearless of consequences, is a diamond of enormous size.

To realize that you were mistaken, is just the acknowledgement , that you are wiser today than you were yesterday.

The affectation of sanctity is a blotch on the face of piety.

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