Such things, and many more of a similar character, are shown by the direct observation of children and the consideration of their vivid childish recollections, which are not influenced by the analysis. You will conclude, among other things, that the position of a child in the sequence of his brothers and sisters is of utmost importance for the entire course of his later life, a factor which should be considered in every biography. In the face of these explanations that are found with so little effort, you will hardly recall without smiling the scientific explanations for the prohibition of incest. What inventions! By living together from early childhood the sexual attraction must have been diverted from these members of the family who are of opposite sex, or a biological tendency against in-breeding finds its psychic equivalent in an innate dread of incest! In this no account is taken of the fact that there would be no need of so unrelenting a prohibition by law and morality if there were any natural reliable guards against the temptation of incest. Just the opposite is true. The first choice of an object among human beings is regularly an incestuous one, in the man directed toward the mother and sister, and the most stringent laws are necessary to prevent this persisting infantile tendency from becoming active. Among the primitive races the prohibitions against incest are much more stringent than ours, and recently Th. Reik showed in a brilliant paper that the puberty-rites of the savages, which represent a rebirth, have the significance of loosing the incestuous bonds of the boy to his mother, and of establishing the reconciliation with the father. Mythology teaches that incest, apparently so abhorred by men, is permitted to the gods without further thought, and you may learn from ancient history that incestuous marriage with his sister was holy prescript for the person of the ruler (among the ancient Pharaohs and the Incas of Peru). We have here a privilege denied the common herd.
