On the contrary, the most urgent problem today is how to limit and discourage the over-fertility of the mentally and physically defective.

Every single case of inherited defect, every malformed child, every congenitally tainted human being brought into this world is of infinite importance to that poor individual; but it is of scarcely less importance to the rest of us and to all of our children who must pay in one way or another for these biological and racial mistakes.

By all means, there should be no children when either mother or father suffers from such diseases as tuberculosis, gonorrhea, syphilis, cancer, epilepsy, insanity, drunkenness and mental disorders. In the case of the mother, heart disease, kidney trouble and pelvic deformities are also a serious bar to childbearing No more children should be born when the parents, though healthy themselves, find that their children are physically or mentally defective.
