Chapter 8, "Dangers of Cradle Competition"

While it is necessary to point out the importance of "heredity" as a determining factor in human life, it is fatal to elevate it to the position of an absolute. As with environment, the concept of heredity derives its value and its meaning only in so far as it is embodied and made concrete in generations of living organisms. Environment and heredity are not antagonistic. Our problem is not that of "Nature vs. Nurture," but rather of Nature x Nurture, of heredity multiplied by environment, if we may express it thus. The Eugenist who overlooks the importance of environment as a determining factor in human life, is as short-sighted as the Socialist who neglects the biological nature of man. We cannot disentangle these two forces, except in theory. To the child in the womb, said Samuel Butler, the mother is "environment." She is, of course, likewise "heredity." The age-old discussion of "Nature vs. Nurture" has been threshed out time after time, usually fruitlessly, because of a failure to recognize the indivisibility of these biological factors. The opposition or antagonism between them is an artificial and academic one, having no basis in the living organism.
