The noble man honours in himself the powerful one, him also who has power over himself, who knows how to speak and how to keep silence, who takes pleasure in subjecting himself to severity and hardness, and has reverence for all that is severe and hard.
Friedrich NietzscheMan, however, is the most courageous animal: thereby has he overcome every animal. With sound of triumph has he overcome every pain; human pain, however, is the sorest pain.
Friedrich NietzscheWhen one speaks of humanity, the idea is fundamental that this is something which separates and distinguishes man from nature. In reality, however, there is no such separation: "natural" qualities and those called truly "human" are inseparably grown together. Man, in his highest and noblest capacities, is wholly nature and embodies its uncanny dual character. Those of his abilities which are terrifying and considered inhuman may even be the fertile soil out of which alone all humanity can grow in impulse, deed, and work.
