A letter is a soul, so faithful an echo of the speaking voice that to the sensitive it is among the richest treasures of love.

They [twin beds] are the most stupid, the most perfidious, and the most dangerous invention in the world. Shame and a curse on who thought of them.

No woman dares to refuse love without a motive, for nothing is more natural than to yield to love.

To man, faith; to woman, doubt. She bears the heavier burden. Does not woman invariably suffer for two?

A monster which devours everything - that is familiarity.

The world will avenge itself upon all happiness in which it has no share.

Virtue in women is perhaps a question of temperament.
