Whatever does not kill me makes me stronger.

The love of power is the demon of mankind.

How much truth does a spirit endure, how much truth does it dare?

The sick are the greatest danger for the healthy; it is not from the strongest that harm comes to the strong, but from the weakest.

Sometimes it is harder to accede to a thing than it is to see its truth.

But tell me: how did gold get to be the highest value? Because it is uncommon and useless and gleaming and gentle in its brilliance; it always gives itself. Only as an image of the highest virtue did gold get to be the highest value. The giver's glance gleams like gold. A golden brilliance concludes peace between the moon and the sun. Uncommon is the highest virtue and useless, it is gleaming and gentle in its brilliance: a gift-giving virtue is the highest virtue.

Rendering oneself unarmed when one had been the best-armed, out of a height of feeling-that is the means to real peace, which must always rest on a peace of mind.
