It is not only in themselves that the feeble-minded are a burden on the present generation and a menace to future generations. In large measure they form the reservoir from which the predatory classes are recruited. This is, for instance, the case as regards prostitutes. Feeble-minded girls, of fairly high grade, may often be said to be predestined to prostitution if left to themselves, not because they are vicious, but because they are weak and have little power of resistance. They cannot properly weigh their actions against the results of their actions, and even if they are intelligent enough to do that, they are still too weak to regulate their actions accordingly. Moreover, even when, as often happens among the high-grade feeble-minded, they are quite able and willing to work, after they have lost their "respectability" by having a child, the opportunities for work become more restricted, and they drift into prostitution. It has been found that of nearly 15,000 women who passed through Magdalen Homes in England, over 2500, or more than sixteen per cent--and this is probably an under-estimate--were definitely feeble-minded. The women belonging to this feeble-minded group were known to have added 1000 illegitimate children to the population. In Germany Bonhoeffer found among 190 prostitutes who passed through a prison that 102 were hereditarily degenerate and 53 feeble-minded. This would be an over-estimate as regards average prostitutes, though the offences were no doubt usually trivial, but in any case the association between prostitution and feeble-mindedness is intimate. Everywhere, there can be no doubt, the ranks of prostitution contain a considerable proportion of women who were, at the very outset, in some slight degree feeble-minded, mentally and morally a little blunted through some taint of inheritance.[34]
