La vengeance est un plat qui se mange froid

...it is not for the illusion of a moment to govern the choice of a lifetime.

Don't you remember that love, like medicine, is only the art of encouraging nature?

I see you are already as timid as a slave: you might as well be in love.

Truth to tell, the longer I live, the more I'm tempted to think that the only moderately worthwhile people in the world are you and I.

Humanity is not perfect in any fashion; no more in the case of evil than in that of good. The criminal has his virtues, just as the honest man has his weaknesses.

I assure you that the world is not so amusing as we imagined.
