All belief that does not make us more happy, more free, more loving, more active, more calm, is, I fear, a mistaken and superstitious belief.

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

Loudness is impotence.

Him, who incessantly laughs in the street, you may commonly hear grumbling in his closet.

And still, laughter is akin to weeping.

Be neither too early in the fashion, nor too long out of it; nor at any time in the extremes of it.

Malice is poisoned by her own venom.
