‘Like the Roman emperors, who, intoxicated by their power, at length regarded themselves as demigods, so the ruler of the earth believes that the animals subjected to his will have nothing in common with his own nature. Man is not content to be the king of animals. He insists on having it that an impassable gulf separates him from his subjects. The affinity of the ape disturbs and humbles him. And, turning his back upon the earth, he flies, with his threatened majesty, into the cloudy sphere of a special “human kingdom.” But Anatomy, like those slaves who followed the conqueror’s car crying, “Thou art a man,” disturbs him in his self-admiration, and reminds him of those plain and tangible realities which unite him with the animal world.’
