The foregoing charts tell a story as instructive as it is amazing. We have here a family of good English blood of the middle class, settling upon the original land purchased from the proprietors of the state in Colonial times, and throughout four generations maintaining a reputation for honor and respectability of which they are justly proud. Then a scion of this family, in an unguarded moment, steps aside from the paths of rectitude and with the help of a feeble-minded girl, starts a line of mental defectives that is truly appalling. After this mistake, he returns to the traditions of his family, marries a woman of his own quality, and through her carries on a line of respectability equal to that of his ancestors.

We thus have two series from two different mothers but the same father. These extend for six generations. Both lines live out their lives in practically the same region and in the same environment, except in so far as they themselves, because of their different characters, changed that environment. Indeed, so close are they that in one case a defective man on the bad side of the family was found in the employ of a family on the normal side and, although they are of the same name, neither suspects any relationship.

We thus have a natural experiment of remarkable value to the sociologist and the student of heredity. That we are dealing with a problem of true heredity, no one can doubt, for, although of the descendants of Martin Kallikak Jr. many married into feebleminded families and thus brought in more bad blood, yet Martin Jr. himself married a normal woman, thus demonstrating that the defect is transmitted through the father, at least in this generation. Moreover, the Kallikak family traits appear continually even down to the present generation, and there are many qualities that are alike in both the good and the bad families, thus showing the strength and persistence of the ancestral stock.

The reader will recall the famous story of the Jukes family published by Richard L. Dugdale in 1877,1 a startling array of criminals, paupers, and diseased persons, more or less related to each other and extending over seven generations.

Dr. Winship has undertaken to compare this family with the descendants of Jonathan Edwards,1 and from this comparison to draw certain conclusions. It is a striking comparison, but unfortunately not as conclusive as we need in these days. The two families were utterly independent, of different ancestral stock, reared in different communities, even in different States, and under utterly different environment.

The one, starting from a strong, religious, and highly educated ancestor, has maintained those traits and traditions down to the present day and with remarkable results; the other, starting without any of these advantages, and under an entirely different environment, has resulted in the opposite kind of descendants.

It is not possible to convince the euthenist (who holds that environment is the sole factor) that, had the children of Jonathan Edwards and the children of "Old Max" changed places, the results would not have been such as to show that it was a question of environment and not of heredity. And he cites to us the fact that many children of highly developed parents degenerate and become paupers and criminals, while on the other hand, some children born of lowly and even criminal parents take the opposite course and become respectable and useful citizens.

In as far as the children of "Old Max" were of normal mentality, it is not possible to say what might not have become of them, had they had good training and environment.

Fortunately for the cause of science, the Kallikak family, in the persons of Martin Kallikak Jr. and his descendants, are not open to this argument. They were feeble-minded, and no amount of education or good environment can change a feeble-minded individual into a normal one, any more than it can change a redhaired stock into a black-haired stock. The striking fact of the enormous proportion of feeble-minded individuals in the descendants of Martin Kallikak Jr. and the total absence of such in the descendants of his half brothers and sisters is conclusive on this point. Clearly it was not environment that has made that good family. They made their environment; and their own good blood, with the good blood in the families into which they married, told.

So far as the Jukes family is concerned, there is nothing that proves the hereditary character of any of the crime, pauperism, or prostitution that was found. The most that one can say is that if such a family is allowed to go on and develop in its own way unmolested, it is pretty certain not to improve, but rather to propagate its own kind and fill the world with degenerates of one form or another. The formerly much-discussed question of the hereditary character of crime received no solution from the Jukes family, but in the light of present-day knowledge of the sciences of criminology and biology, there is every reason to conclude that criminals are made and not born. The best material out of which to make criminals, and perhaps the material from which they are most frequently made, is feeble-mindedness.

The reader must remember that the type of feeble-mindedness of which we are speaking is the one to which Deborah belongs, that is, to the high grade, or moron. All the facts go to show that this type of people makes up a large percentage of our criminals.1 We may argue a priori that such would be the case. Here we have a group who, when children in school, cannot learn the things that are given them to learn, because through their mental defect, they are incapable of mastering abstractions. They never learn to read sufficiently well to make reading pleasurable or of practical use to them. The same is true of number work. Under our compulsory school system and our present courses of study, we compel these children to go to school, and attempt to teach them the three R's, and even higher subjects. Thus they worry along through a few grades until they are fourteen years old and then leave school, not having learned anything of value or that can help them to make even a meager living in the world. They are then turned out inevitably dependent upon others. A few have relatives who take care of them, see that they learn to do something which perhaps will help in their support, and then these relatives supplement this with enough to insure them a living.

A great majority, however, having no such interested or capable relatives, become at once a direct burden upon society. These 1 See Goddard, Feeble-mindedness; Its Causes and Consequences, 1914. Also The Criminal Imbecile, 1915, by the same author. — ED.

divide according to temperament into two groups. Those who are phlegmatic, sluggish, indolent, simply lie down and would starve to death, if some one did not help them. When they come to the attention of our charitable organizations, they are picked up and sent to the almshouse, if they cannot be made to work. The other type is of the nervous, excitable, irritable kind who try to make a living, and not being able to do it by a fair day's work and honest wages, attempt to succeed through dishonest methods. "Fraud is the force of weak natures." These become the criminal type. The kind of criminality into which they fall seems to depend largely upon their environment. If they are associated with vicious but intelligent people, they become the dupes for carrying out any of the hazardous schemes that their more intelligent associates plan for them. Because of their stupidity, they are very apt to be caught quickly and sent to the reformatory or prison. If they are girls, one of the easiest things for them to fall into is a life of prostitution, because they have natural instincts with no power of control and no intelligence to understand the wiles and schemes of the white slaver, the cadet, or the individual seducer. All this, we say, is what is to be expected. These are the people of good outward appearance, but of low intelligence, who pass through school without acquiring any efficiency, then go out into the world and must inevitably fall into some such life as we have pictured.

Let us now turn to our public institutions. These have not yet been sufficiently investigated, nor have we adequate statistics to show what percentage of their inmates is actually feeble-minded. But even casual observation of our almshouse population shows the majority to be of decidedly low mentality, while careful tests would undoubtedly increase this percentage very materially.

In our insane hospitals may also be found a group of people whom the physicians will tell you are only partially demented. The fact is they properly belong in an institution for feebleminded, rather than in one for the insane, and have gotten into the latter because an unenlightened public does not recognize the difference between a person who has lost his mind and one who never had one.
