The fight against syphilis and its pace-maker, prostitution, is one of the gigantic tasks of mankind; gigantic, because it is not merely a case of solving a single problem but the removal of a whole series of evils which are the contributory causes of this scourge. Disease of the body in this case is merely the result of a diseased condition of the moral, social, and racial instincts.
But if for reasons of indolence or cowardice this fight is not fought to a finish we may imagine what conditions will be like 500 years hence. Little of God's image will be left in human nature, except to mock the Creator.
