Normally every activity engaged in for its own sake reaches out beyond its immediate self. It does not passively wait for information to be bestowed which will increase its meaning; it seeks it out. Curiosity is not an accidental isolated possession; it is a necessary consequence of the fact that an experience is a moving, changing thing, involving all kinds of connections with other things. Curiosity is but the tendency to make these conditions perceptible. It is the business of educators to supply an environment so that this reaching out of an experience may be fruitfully rewarded and kept continuously active. Within a certain kind of environment, an activity may be checked so that the only meaning which accrues is of its direct and tangible isolated outcome. One may cook, or hammer, or walk, and the resulting consequences may not take the mind any farther than the consequences of cooking, hammering, and walking in the literal--or physical--sense. But nevertheless the consequences of the act remain far-reaching. To walk involves a displacement and reaction of the resisting earth, whose thrill is felt wherever there is matter. It involves the structure of the limbs and the nervous system; the principles of mechanics. To cook is to utilize heat and moisture to change the chemical relations of food materials; it has a bearing upon the assimilation of food and the growth of the body. The utmost that the most learned men of science know in physics, chemistry, physiology is not enough to make all these consequences and connections perceptible. The task of education, once more, is to see to it that such activities are performed in such ways and under such conditions as render these conditions as perceptible as possible. To "learn geography" is to gain in power to perceive the spatial, the natural, connections of an ordinary act; to "learn history" is essentially to gain in power to recognize its human connections. For what is called geography as a formulated study is simply the body of facts and principles which have been discovered in other men's experience about the natural medium in which we live, and in connection with which the particular acts of our life have an explanation. So history as a formulated study is but the body of known facts about the activities and sufferings of the social groups with which our own lives are continuous, and through reference to which our own customs and institutions are illuminated.
