2. The Complementary Nature of History and Geography. History and geography--including in the latter, for reasons about to be mentioned, nature study--are the information studies par excellence of the schools. Examination of the materials and the method of their use will make clear that the difference between penetration of this information into living experience and its mere piling up in isolated heaps depends upon whether these studies are faithful to the interdependence of man and nature which affords these studies their justification. Nowhere, however, is there greater danger that subject matter will be accepted as appropriate educational material simply because it has become customary to teach and learn it. The idea of a philosophic reason for it, because of the function of the material in a worthy transformation of experience, is looked upon as a vain fancy, or as supplying a high-sounding phraseology in support of what is already done. The words "history" and "geography" suggest simply the matter which has been traditionally sanctioned in the schools. The mass and variety of this matter discourage an attempt to see what it really stands for, and how it can be so taught as to fulfill its mission in the experience of pupils. But unless the idea that there is a unifying and social direction in education is a farcical pretense, subjects that bulk as large in the curriculum as history and geography, must represent a general function in the development of a truly socialized and intellectualized experience. The discovery of this function must be employed as a criterion for trying and sifting the facts taught and the methods used. The function of historical and geographical subject matter has been stated; it is to enrich and liberate the more direct and personal contacts of life by furnishing their context, their background and outlook. While geography emphasizes the physical side and history the social, these are only emphases in a common topic, namely, the associated life of men. For this associated life, with its experiments, its ways and means, its achievements and failures, does not go on in the sky nor yet in a vacuum. It takes place on the earth. This setting of nature does not bear to social activities the relation that the scenery of a theatrical performance bears to a dramatic representation; it enters into the very make-up of the social happenings that form history. Nature is the medium of social occurrences. It furnishes original stimuli; it supplies obstacles and resources. Civilization is the progressive mastery of its varied energies. When this interdependence of the study of history, representing the human emphasis, with the study of geography, representing the natural, is ignored, history sinks to a listing of dates with an appended inventory of events, labeled "important"; or else it becomes a literary phantasy--for in purely literary history the natural environment is but stage scenery.
