The movement of intelligence in large social wholes is an intricate organic process, in which many types of men participate, and also many traditions and environments under the influence of which these types of men are formed. From these diverse points of view come forecasts and experiments in various directions, accompanied by a general process of discussion in which all points of view are modified and a fresh synthesis is worked out. Thus we think our way along from one stage to another. Accordingly, every group needs to have what we call in the individual “a fertile mind”; so that, as new situations arise, a goodly number of intelligent ideas may spring up to meet them, out of which the best lines of action may be evolved through the usual methods of discussion and trial. Thus, if a group of boys have to camp in a rocky place where no tent-stakes can be driven, their success in putting up the tent will depend upon having among their number those whose ingenuity or experience will suggest good plans for using stones or logs instead of stakes. We need, then, to encourage the growth of special lines of tradition and association in order that we may have expert guidance. So biologists may suggest plans for improving the breed of animals and the quality and yield of crops, bankers schemes of finance, and men trained in the labor movement methods of conciliation. We cannot expect to reach high levels of intelligence except through the medium of functional groups which, by some adequate process of selection and training have come to represent as nearly as may be the highest attainable faculty in a given direction. These groups must be small, because there must be many of them and because the members must be specially qualified; but there is nothing undemocratic in them. Indeed the more democratic they are, that is, the more selection is based on fair play and equal opportunity, the more efficient they should be. It is essential, however, that they should have a continuous organization, making possible a group spirit and a regular development through tradition and discussion. There is no reason why democracy should not express itself through such groups at least as successfully as any other form of society.
