The use of the terms "fit" and "unfit" in a eugenic sense has been criticized. It is said, for instance, that in a bad environment it may be precisely the defective classes who are most "fit" to survive. It is quite true that these terms are not well adapted to resist hyper-critical attack. The persistence with which they are employed seems, however, to indicate a certain "survival of the fittest." The terms "worthy" and "unworthy," which some would prefer to substitute, are unsatisfactory, for they have moral associations which are misleading. Galton spoke of "civic worth" in this connection, and very occasionally used the term "worthy" (with inverted commas), but he was careful to point out (Essays in Eugenics, p. 35) that in eugenics "we must leave morals as far as possible out of the discussion, not entangling ourselves with the almost hopeless difficulties they raise as to whether a character as a whole is good or bad."

Dr. Toulouse has devoted a whole volume to the results of a minute personal examination of Zola, the novelist, and another to Poincaré, the mathematician. Such minute investigations are at present confined to men of genius, but some day, perhaps, we shall consider that from the eugenic standpoint all men are men of genius.

Sterilization for social ends was introduced in Switzerland a few years ago, in order to enable some persons with impaired self-control to be set at liberty and resume work without the risk of adding to the population defective members who would probably be a burden on the community. It was performed with the consent of the subjects (in some cases at their urgent request) and their relations, so requiring no special legislation,
