THE PROBLEM OF THE BIRTH SUPPLY
negative side, we find a general expression unserviceable for our use.[1]
But it will be alleged that although criminality as a whole means nothing definite enough for our purpose, there can be picked out and defined certain criminal (or at any rate disastrous) tendencies that are simple, specific and transmissible. Those who have read Mr. Archdall Reid's "Alcoholism," for example, will know that he deals constantly with what is called the "drink craving" as if it were such a specific simple inheritance. He makes a very strong case for this belief; but strong as it is, I do not think it is going to stand the pressure of a rigorously critical examination. He points out that races which have been in possession of alcoholic drinks the longest are the least drunken, and this he ascribes to the "elimination" of all those whose "drink craving" is too strong for them. Nations unused to alcoholic drink are most terribly ravaged at its first coming to them, may even be destroyed by it, in precisely the same way that new diseases coming to peoples unused to them are far more malignant than among peoples who have suffered from them generation after generation. Such instances as the terrible ravages of measles in Polynesia and the ruin worked by fire-water among the Red Indians, he gives in
- ↑ No doubt the home of the criminal and social failure is generally disastrous to the children born into it. That is a question that will be fully dealt with in a subsequent paper, and I note it here only to point out that it is outside our present discussion, which is concerned not with the fate of children born into the world, but with the prior question whether we may hope to improve the quality of the average birth by encouraging some sorts of people to have children and discouraging or forbidding others. It is of vital importance to keep these two questions distinct, if we are to get at last to a basis for effective action.
