"Passing from quantity to quality of population, we come to the question of eugenics. We may perhaps assume that, if people grow less superstitious, government will acquire the right to sterilize those who are not considered desirable as parents. This power will be used, at first, to diminish imbecility, a most desirable object. But probably, in time, opposition to the government will be taken to prove imbecility, so that rebels of all kinds will be sterilized. Epileptics, consumptives, dipsomaniacs and so on will gradually be included; in the end, there will be a tendency to include all who fail to pass the usual school examinations. The result will be to increase the average intelligence; in the long run, it may be greatly increased. But probably the effect upon really exceptional intelligence will be bad. Mr. Micawber, who was Dickens's father, would hardly have been regarded as a desirable parent. How many imbeciles ought to outweigh one Dickens I do not profess to know.Eugenics has, of course, more ambitious possibilities in a more distant future. It may aim not only at eliminating undesired types, but at increasing desired types. Moral standards may alter so as to make it possible for one man to be the sire of a vast progeny by many different mothers. When men of science envisage a possibility of this kind, they are prone to a type of fallacy which is common also in other directions. They imagine that a reform inaugurated by men of science would be administered as men of science would wish, by men similar in outlook to those who have advocated it. In like manner women who advocated votes for women used to imagine that the woman voter of the future would resemble the ardent feminist who won her the vote; and socialist leaders imagine that a socialist State would be administered by idealistic reformers like themselves. These are, of course, delusions; a reform, once achieved, is handed over to the average citizen. So, if eugenics reached the point where it could increase desired types, it would not be the types desired by present-day eugenists that would be increased, but rather the type desired by the average official. Prime Ministers, Bishops, and others whom the State considers desirable might become the fathers of half the next generation. Whether this would be an improvement it is not for me to say, as I have no hope of ever becoming either a Bishop or a Prime Minister."
