Human beings are not children of the sun. They are children of the jungle. We have in our natures many things that we would be a great deal better off without instincts and ways of acting which we would never have included in ourselves in the world if we had had the privilege of choosing just what was to go into our natures. These instincts and ways of acting are vestigial. They were useful to our ancestors, but owing to changes in surroundings they are not useful to us.

These races of beings which man has associated with himself are living beings. They eat and drink and breathe, they suffer and enjoy, reproduce their kind and love their young, much as human beings do. They have been taken from their natural surroundings and forced to adopt ways of living that are often cruel, or even horrible. There is nothing much more certain than that men and women of the far future will recognize their kinship with these races, and will treat them in an entirely different way from what we do.

Human institutions are inventions. They are devices to aid in the promotion of human welfare. They should be judged by the same standards of utility as agricultural implements and everything else. Whenever they can be made over to advantage, they should be made over. And whenever they can be rendered useless by something better to take their place, they should be sent without sighs or lamentations to the junkpile. Nothing is too sacred to he improved.
