The human soul is the blossom, not the beginning, of psychic evolution. Mother-love compassionated infancy long before a babe came from the stricken loins of woman. The inhabitants of the earth had been seeking pleasure and seeking to avoid pain, and seeking ever with the same sad futility, long before man with his retinue of puny philosophies strutted upon the scene. Hate poisoned the cisterns of the sea and dropped its pollutions through the steaming spaces ages before there was malice among men. Altruism is older than the mountains, and selfishness hardened the living heart before the continents were lifted. There was wonder in the woods and in the wild heart of the fastnesses before there were waitings in synagogues and genuflections about altar piles. The frogs, crickets, and birds had been singing love a thousand generations and more when the first amoroso knelt in dulcet descant to a beribboned Venus. Human nature is not an article of divine manufacture, any more than is the human form. It came out of the breast of the bird, out of the soul of the quadruped. The human heart does not draw back from the mysterious dissolutions of death more earnestly than does the hare that flees before resounding packs or the wild-fowl that reddens the reeds with its flounderings. Bowerbirds build their nest-side resorts, decorate them with gay feathers, and surround them with grounds ornamented with bright stones and shells, for identically the same reason as human beings design drawing-rooms, hang them with tapestries, and surround them with ornamented lawns. The scarlet waistcoat of the robin and the flaming dresses of tanagers and humming-birds, which seem, as they flash through the forest aisles, like shafts of cardinal-fire, serve the same vanities and minister to the same instincts as the plumage of the dandy and the tints and gewgaws of gorgeous dames. Art is largely a manifestation of sex, and it is about as old and about as persistent as this venerable impulse. How did Darwin’s dog know his master on his master’s return from a five-years’ trip around the world? Just as the boy remembers where the strawberries grow and the philosopher recalls his facts—by that power of the brain to retain and to reproduce past impressions. Why does the thinker search his soul for new theories and the spaces for new stars? For the same reason that the child asks questions and the monkey picks to pieces its toys. What is reason? A habit of wise men—an expedient of ants—a mania the fools of all ages are free from. All of the activities of men, however imposing or peculiar, are but elaborations in one way or another of the humble doings of the animalcule, whose home is a water-drop and whose existence can be discovered by human senses only by the aid of instruments.
