We find, then, that the difficult problem we are considering, like other social problems, has a material aspect, that is a medical aspect, an intellectual aspect, and a spiritual aspect concerning the aims of life: and of these the last is the most fundamental; it is obviously also the most difficult. To attack the situation fully it would be necessary to change most of our contemporary life. We are, however, bound to realize that, if we are to succeed, our attention must shift from saving the fallen, to removing the hindrances and the temptations that are the causes of falling. In other words, we have to provide a society in which the young will find virtue and goodness as serviceable to their needs and as attractive as vice and doing evil. III If we turn now to the practical consideration of the problem before us, we find the situation, difficult as it is, is not without hope. We have to face as the result of the war a task greatly enlarged and growing in difficulties, but if we do so face it--and the very increase in the danger is urging us like spurs in the flesh of a tired horse--we have an exceptionally favorable opportunity for correction and amendment. For one thing, we have become more used to being interfered with, also, I think we have come to understand in a new and more profound way that each man "is his brother's keeper." Again the real difficulty arises now, not so much from our want of good will, as from our failure to act unitedly, and formulate and carry out a wide-reaching program of reform. If for the sake of clarity, we try by classifying motives to form a rough grouping, we find that, as with most political subjects, there are three opinions with regard to proposals for State interference to stay the peril and prevent the spread of venereal disease.
