The color of truth is gray.

Seize from every moment its unique novelty, and do not prepare your joys.

Sadness is a state of sin.

Envying another man's happiness is madness; you wouldn't know what to do with it if you had it.

Generally among intelligent people are found nothing but paralytics and among men of action nothing but fools.

The important thing is being capable of emotions, but to experience only one's own would be a sorry limitation.

Sadness is almost never anything but a form of fatigue.
