The psychology of the exploitation of nonhuman beings by human beings is not different in kind from the psychology of any other act of exploitation. The great first cause of man’s inhumanity to not-men is the same precisely as the great first cause of man’s inhumanity to man—_Selfishness_—blind, brutal, unconscionable egoism. Monopolist-like man thinks and cares only about himself. He has the heart of the bully—deriving from the contemplation of his fiendish supremacy a sort of monstrous satisfaction. But there is also present in this case the same half-sincere, half-fostered nescience as in all other cases of exploitation. The ox, the hare, the bird, and the fish have no rights in the world in which they live other than those that are convenient for men to allow to them, because they are ‘animals.’ They are assumed to belong to an order of beings entirely different from that to which human beings belong. They are filled with nerves, and brains, and bloodvessels; they love life, and bleed, and struggle, and cry out when their veins are opened, just as human beings do; they have the same general form and structure of body, their bodies are composed of the same organs busied with the same functions; and they are descended from the same ancestors and have been developed in the same world through the operation of the same great laws as we ourselves have. But all of these things, and dozens of others just as significant, are disregarded by us in our hard-hearted determination to exploit them. We have a set of words and phrases which we use in speaking of ourselves, and another very different set for other beings. The very same things are called by different names with wholly different connotations depending on whether it is a man that is referred to or some other being. It is ‘murder’ to take the life of a human being, but to take the life of a sheep or a cow is only ‘knocking it on the head.’ A man may murder squirrels or birds all day—that is, he may do that which when done to human beings is called murder—but it is only ‘sport’ when done to these humble inhabitants of the wilds. The dead body of a man is a ‘corpse’; the dead body of a quadruped is only a ‘carcass.’ A race of horses or dogs is a ‘breed’; but a breed of men and women is always respectfully referred to as a race. We perpetuate our blindness by the use of words. We accommodate our consciences by inventing ways of looking at things that will bring out our own lustre and relieve us from the ghastly faces of our crimes. For the human race to rob and kill other races is the same kind of activity exactly as it is for human beings to rob and kill each other. But it is not considered so to-day—except by a few lost-caste ‘visionaries’ scattered here and there over Christendom, and some millions of ‘heathens’ in Asia.
