In conclusion, we note that the early history of the idea of following nature combined two factors which had no inherent connection with one another. Before the time of Rousseau educational reformers had been inclined to urge the importance of education by ascribing practically unlimited power to it. All the differences between peoples and between classes and persons among the same people were said to be due to differences of training, of exercise, and practice. Originally, mind, reason, understanding is, for all practical purposes, the same in all. This essential identity of mind means the essential equality of all and the possibility of bringing them all to the same level. As a protest against this view, the doctrine of accord with nature meant a much less formal and abstract view of mind and its powers. It substituted specific instincts and impulses and physiological capacities, differing from individual to individual (just as they differ, as Rousseau pointed out, even in dogs of the same litter), for abstract faculties of discernment, memory, and generalization. Upon this side, the doctrine of educative accord with nature has been reinforced by the development of modern biology, physiology, and psychology. It means, in effect, that great as is the significance of nurture, of modification, and transformation through direct educational effort, nature, or unlearned capacities, affords the foundation and ultimate resources for such nurture. On the other hand, the doctrine of following nature was a political dogma. It meant a rebellion against existing social institutions, customs, and ideals (See ante, p. 91). Rousseau's statement that everything is good as it comes from the hands of the Creator has its signification only in its contrast with the concluding part of the same sentence: "Everything degenerates in the hands of man." And again he says: "Natural man has an absolute value; he is a numerical unit, a complete integer and has no relation save to himself and to his fellow man. Civilized man is only a relative unit, the numerator of a fraction whose value depends upon its dominator, its relation to the integral body of society. Good political institutions are those which make a man unnatural." It is upon this conception of the artificial and harmful character of organized social life as it now exists 2 that he rested the notion that nature not merely furnishes prime forces which initiate growth but also its plan and goal. That evil institutions and customs work almost automatically to give a wrong education which the most careful schooling cannot offset is true enough; but the conclusion is not to education apart from the environment, but to provide an environment in which native powers will be put to better uses.
