Behold how each of your virtues is covetous for the highest: it longs for your whole spirit to be its herald, it longs for your whole power in wrath, love and hatred.

Jealous is each virtue of the other, and a terrible thing is jealousy. Even virtues may perish from jealousy.

He who is encompassed by the flame of jealousy, at last, like the scorpion, turns the poisonous sting toward himself.

Alas, my brother, did you never see a virtue backbite and stab itself?

Man is a something that must be surpassed: and therefore you shall love your virtues - for you will perish from them.
