> Socrates used to say, ‘What do you want? To have the souls of rational or irrational beings?’ ‘Of rational beings.’ And of what kind of rational beings, those that are sound or depraved?’ ‘Those that are sound.’ ‘Then why are you not seeking for them?’ ‘Because we have them.’ ‘Then why all this fighting and quarrelling?’

-- Marcus Aurelius, "Meditations"

On the other hand, I also really like this, even though it's probably one of those fake internet quotes:

> If your heart is broken, don't try to fix it, they work better that way.

-- Tibetan monk
