There are only two kinds of men: the righteous who think they are sinners and the sinners who think they are righteous.

If all men knew what others say of them, there would not be four friends in the world.

As men are not able to fight against death, misery, ignorance, they have taken it into their heads, in order to be happy, not to think of them at all.

The sensitivity of men to small matters, and their indifference to great ones, indicates a strange inversion.

Two things control men's nature, instinct and experience.
