Racial decay in modern society; Purely "moral" control dysgenic in civilized society; New machinery for social control; Mistaken notion that reproduction is an individual problem; Economic and other factors in the group problem of reproduction. From the discussion in the preceding chapter, it becomes apparent that for the half of the female element in a savage society possessing the most vigor and initiative to turn away from reproduction would in the long run be fatal to the group. Yet this is what occurs in large measure in modern civilized society. Reproduction is a biological function. It is non-competitive, as far as the individual is concerned, and offers no material rewards. The breakdown of the group's control over the detailed conduct and behaviour of its members is accompanied by an increasing stress upon material rewards to individuals. So with growing individualism, in the half of the race which can both bear children and compete in the social activities offering rewards, i.e., the women who are specialized to the former and adapted to the latter, there is a growing tendency among the most successful, individualized strains, to choose the social and eschew the biological functions. Racial degeneration is the result. Recorded history is one succession of barbarous races, under strong, primitive breeding conditions, swamping their more civilized, individualized neighbours, adopting the dysgenic ways of civilization and then being swamped in their turn by barbarians. This is especially pronounced in our own times because popularized biological and medical knowledge makes it possible for a tremendous class of the most successful and enlightened to avoid reproduction without foregoing sex activity. In primitive groups, a "moral" control which kept all women at reproduction was neither eugenic nor dysgenic unless accompanied by systematic destruction of the least fit children. By "moral" control is meant the use of taboo, prejudice, religious abhorrence for certain acts and the like. The carefully nurtured moral ideas about sex and reproduction simply represent the system of coercion which groups have found most effective in enforcing the division of reproductive and other activities among the individual members. When this social machinery grew up, to regulate sexual activity was in general to regulate reproduction. The natural sex desire proved sufficiently powerful and general to still seek its object, even with the group handicaps and regulations imposed to meet the reproductive necessity. But contraceptive knowledge, etc., has now become so general that to regulate sex activity is no longer to regulate reproduction. The taboo or "moral" method of regulation has become peculiarly degenerating to race quality, because the most intelligent, rationalized individuals are least affected by it.
