What is to be done? In one point we all agree: Those who are called to do so must bend their utmost energy toward the purification of the outer forms of community life and of the public institutions. Certain eugenic ideas must be carried through relentlessly; above all, the sexual segregation of the feeble-minded, whose progeny fills the houses of disorder and the ranks of the prostitutes. The hospitals must be wide open for every sexual disease, and all discrimination against diseases which may be acquired by sexual intercourse must be utterly given up in order to stamp out this scourge of mankind, as far as possible, with the medical knowledge of our day. Every effort must be made to suppress places through which unclean temptations are influencing the youth. Parents and doctors should speak in the intimacy of private talk earnest words of warning. The fight against police corruption and graft must be relentlessly carried on so as to have the violation of the laws really punished. Many means may still seem debatable among those who know the social and medical facts. Certainly some of the eugenic postulates go too far. It is, for instance, extremely difficult to say where the limit is to be set for permissible marriages. There may be no doubt that feeble-mindedness ought not to be transmitted to the next generation, but have we really a right to prevent the marriage of epileptics or psychasthenics? Can we be surprised then that others already begin to demand that neurasthenics shall not marry? Even the health certificate at the wedding may give only an illusion of safety, as the health of too many marriages is destroyed by the escapades of the husband, and it may, on the other hand, lead to a narrowing down under the pressure of arbitrary theories, producing a true race suicide. The question whether the healthy man is the only desirable element of the community is one which allows different answers. Much of the greatest work for the world's progress has been created by men with faulty animal constitutions whose parents would never have received permission to marry from a rigorous eugenic board.
