What makes us so bitter against people who outwit us is that they think themselves cleverer than we are.

What makes lovers never tire of one another is that they talk always about themselves.

Whatever pretended causes we may blame our afflictions upon, it is often nothing but self-interest and vanity that produce them.

We seldom find people ungrateful so long as it is thought we can serve them.

We rarely think people have good sense unless they agree with us.

We give advice, we do not inspire conduct.

Moderation is an ostentatious proof of our strength of character.
