When 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.

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.
