Sympathy is consciousness of kind. It is the putting of one's self in the place of another, the projection of one's own personality into the peripher… - J. Howard Moore

One thing is certain, however, and that is, that the most powerful instinct of human nature, the instinct to struggle and survive, the instinct to be superior, must be destroyed or greatly subordinated before the state here outlined can be realized; for the ideal state will be practically bereft of opportunity for its satisfaction.

This is the ideal:
Man takes these races from the plains, where they are exposed to hunger and thirst and cold, harassed by enemies, and victimized by their own child-like intelligence. He associates them with himself. He gives them security, shelter, regular food, intellectual surroundings, and a home. They give to him in return the benefits of their superior strength and speed, bearing man and his burdens, wielding his great machines for him, and supplementing in a thousand ways the inadequate powers of their mentor.

The frail, narrow, fantastic character of human sympathy is the most mournful fact in human nature. 'Man's inhumanity to man makes countless thousands mourn,' and his inhumanity to not-men makes the planet a ball of pain and terror.
