Of the original source from which syphilis sprang, of its implication in the sex problem, and of the ultimate eradication of its virus—to be attained only by the true solution of the sex problem—we cannot here speak; the point under immediate consideration is the fact that the civilized races of mankind persist in propagating and perpetuating disease. They unscrupulously bring into the world individual organisms that are pre-destined to failure because not endowed with the potential qualities indispensable to complete and successful life. In America the same conditions are noted and publicly referred to. Mr. Nathan Allen, M.D., before a medical society at Massachusetts, reported: “A gradual change is taking place in the organization of our New England people—a change which has occurred principally within the last two or three generations. The nervous temperament with all its advantages and disadvantages is becoming too predominant for other parts of the body. The frame-work of the body generally is not so large ... the countenance is paler, the features are more pointed and not so expressive of health. We have a larger class of diseases arising from general debility ... we have more disease of the brain and nervous system, more sudden deaths from apoplexy, paralysis, and also diseases of the heart. In sound healthy stock we have in a far higher degree the recuperative powers of nature; while the original constitution is feeble, diseases of almost every kind become complicated, and their treatment more difficult as well as doubtful in result.” Laws of inheritance affect the moral as well as the physical and mental health of the nation. Their action is fatally legible in the public records of crime. Not that many criminals inherit the actual attributes of crime—brutality, cruelty, malignity, propensity to abnormal sexual practices—these develop through the interaction of external with internal forces—but the ordinary criminal is born deficient in the elemental qualities necessary to the establishment of the average moral nature.
