The greatest happiness is to know the source of unhappiness.

Happiness does not lie in happiness, but in the achievement of it.

Do you think it is a vain hope that one day man will find joy in noble deeds of light and mercy, rather than in the coarse pleasures he indulges in today -- gluttony, fornication, ostentation, boasting, and envious vying with his neighbor? I am certain this is not a vain hope and that the day will come soon.

To care only for well-being seems to me positively ill-bred. Whether it’s good or bad, it is sometimes very pleasant, too, to smash things.

Man is unhappy because he doesn't know he's happy. If anyone finds out he'll become happy at once.

It's a burden to us even to be human beings-men with our own real body and blood; we are ashamed of it, we think it a disgrace and try to contrive to be some sort of impossible generalized man.

A fool with a heart and no sense is just as unhappy as a fool with sense and no heart.
