We need to know vastly more than we know to-day before we can give definite answers, except in the case of marriage between two feeble-minded persons. Now, that being the case, the argument that I want to make to you is: the propagation of the feeble-minded is going on at an enormous rate. If we could do, and if we did, everything that we wanted to do, and that we knew enough to do, we should be getting only at the surface of the problem, and should be sure in only about one case out of the six possibilities. Now if that is the case, my friends, does it seem that we ought to put off attacking the problem until we cannot stand it any longer? Or does it mean that we had better attack it right away? Is it not best to begin hunting for these defective children wherever they may be found? And they can be found in the school, in our juvenile courts, in our almshouses, in our insane hospitals, in our reform schools, in our homes for cripples, in our asylums for the blind,—in short, wherever there is a dependent group there is an undue proportion of these mental defectives. Some will say, “If they are in almshouses they are being cared for.” In reality they are being raised and brought to manhood and womanhood and then sent out, to propagate their kind. Fifty years ago the problem was not as serious as it is to-day, because these defectives were out in the world by themselves, getting killed by a runaway horse, or falling into machinery, or in some way meeting an untimely death. To-day we are exceedingly careful; we are protecting them in every possible way; we are taking care of them in our institutions and giving them every advantage, and then sending them out into the world—a menace to the rest of humanity. It would be a dreadful thing if all these problems were solved and we didn’t have any people to give our money and charity to. I suppose we should become hard-hearted if we didn’t have any to befriend. Perhaps we want to keep enough of these unfortunates so that we can still contribute to their safety and welfare. But, my friends, when we realize the suffering, the terrors, the losses of all kinds that these people unintentionally, unwittingly cause us, we have another side of the problem. The menace of the feeble-minded is not a figure of speech. It is no undue sentimentalism that assures us that we need to take care of this group of people. We need to study them very seriously and very thoroughly; we need to hunt them out in every possible place and take care of them, and see to it that they do not propagate and make the problem worse, and that those who are alive to-day do not entail loss of life and property and moral contagion in the community by the things that they do because they are weak-minded.
