CHAPTER III SOCIETY AND STATE IN RELATION TO THE LAND [Sidenote: People and land.] Every clan, tribe, state or nation includes two ideas, a people and its land, the first unthinkable without the other. History, sociology, ethnology touch only the inhabited areas of the earth. These areas gain their final significance because of the people who occupy them; their local conditions of climate, soil, natural resources, physical features and geographic situation are important primarily as factors in the development of actual or possible inhabitants. A land is fully comprehended only when studied in the light of its influence upon its people, and a people cannot be understood apart from the field of its activities. More than this, human activities are fully intelligible only in relation to the various geographic conditions which have stimulated them in different parts of the world. The principles of the evolution of navigation, of agriculture, of trade, as also the theory of population, can never reach their correct and final statement, unless the data for the conclusions are drawn from every part of the world, and each fact interpreted in the light of the local conditions whence it sprang. Therefore anthropology, sociology and history should be permeated by geography. [Sidenote: Political geography and history.]
