One may outwit another, but not all the others.

Folly pursues us at all periods of our lives. If someone seems wise it is only because his follies are proportionate to his age and fortune.

Whatever good things people say of us, they tell us nothing new.

There are but very few men clever enough to know all the mischief they do.

The most clever and polite are content with only seeming attentive while we perceive in their mind and eyes that at the very time they are wandering from what is said and desire to return to what they want to say.

In friendship, as in love, we are often more happy from the things we are ignorant of than from those we are acquainted with.

The intention of never deceiving often exposes us to deception.
