Inevitably, customs, morals, codes of procedure and practice, institutions, all those expressions of opinion which make conduct, all the currents which contrive the infinite variety of life, will be transmitted into another set of values. A remoulding, a remodeling will take place all along the line. Manifestly an unstable thymocentric should not be treated as a criminal, but treated in a sanitarium. A masculinoid woman needs satisfactions not vouchsafed in the old "love, honor and obey" home. How absurd it is to found codes of morality upon sermons or even the latest psychologies. During the nineteenth century progress in physics and mechanics overturned traditions thousands of years had painfully toiled to erect. What is to happen when man comes at last to experiment upon himself like a god, dealing not only with the materials without, but also with the very constituents of his innermost being? Will he not then indeed become a god? If he does not destroy himself before, that is surely his destiny. For better or for worse, we possess now in the endocrines new instruments for swaying the individual as individual, and as related to other individuals, as a member of a type, family, nation, species and genus. THE BASIS OF VARIATION The sense of likeness and the sense of unlikeness plays a decisive rôle in the diurnal schedule of the individual. His sense of resemblance to his father and mother, his kin and clan, mark him and them off against the cosmos as an alliance of defense and offense. Yet no matter how closely he is like them and they like him, he differs and varies, they differ and vary, with a sort of mutual forgiveness, because the amount of resemblance overtops the degree of variation. In a paper on the "Rediscovery of the Unique," H.G. Wells emphasized the unique quality of the individual, and how, in spite of the cleverest devices of classification, living things ultimately escaped the classifying net by virtue of their tendency forever to vary. The individual is unique. Yet when all is said and done, the fact remains that between individuals there is resemblance, and among them variation. What is the reason for their resemblances and what is the cause of their variation?
