"Write Man for Primula, and the stage of the world for that of the greenhouse," says Professor Bateson (Biological Fact and the Structure of Society, 1912, p. 9), "and I believe that with a few generations of experimental breeding we should acquire the power similarly to determine how the varieties of men should be represented in the generations that succeed." But Bateson proceeds to point out that our knowledge is still very inadequate, and he is opposed to eugenics by Act of Parliament.

Only a year before his death Galton wrote (Preface to Essays in Eugenics): "The power by which Eugenic reform must chiefly be effected is that of Popular Opinion, which is amply strong enough for that purpose whenever it shall be roused."

It may perhaps be necessary to remark that by sterilization is here meant, not castration, but, in the male vasectomy (and a corresponding operation in the female), a simple and harmless operation which involves no real mutilation and no loss of power beyond that of procreation. See on this and related points, Havelock Ellis, Studies in the Psychology of Sex, Vol. VI, "Sex in Relation to Society," chap. xii.
