We have only to turn our attention to the social life around us to observe evidences of the great importance of economic factors. Even now it will be observed that the greater part of economic activities proceeds from the effort to procure food, clothing, and shelter, while a relatively smaller part is engaged in the pursuit of education, culture, and pleasure. The excellence of educational systems, the highest flights of philosophy, the greatest achievement of art, and the best inspiration of religion cannot exist without a wholesome economic life at the foundation. It should not be humiliating to man that this is so, for in the constitution of things, labor of body and mind, the struggle for existence and the accumulations of the products of industry yield a large return in themselves in discipline and culture; and while we use these economic means to reach higher ideal states, they represent the ladder on which man makes the first rounds of his ascent. _The Methods of Procuring Food in Primitive Times_.--Judging from the races and tribes that are more nearly in a state of nature than any other, it may be reasonably assumed that {84} in his first stage of existence, man subsisted almost wholly upon a vegetable diet, and that gradually he gave more and more attention to animal food. His structure and physiology make it possible for him to use both animal and vegetable food. Primarily, with equal satisfaction the procuring of food must have been rather an individual than a social function. Each individual sought his own breakfast wherever he might find it. It was true then, as now, that people proceeded to the breakfast table in an aggregation, and flocked around the centres of food supply; so we may assume the picture of man stealing away alone, picking fruits, nuts, berries, gathering clams or fish, was no more common than the fact of present-day man getting his own breakfast alone. The main difference is that in the former condition individuals obtained the food as nature left it, and passed it directly from the bush or tree to the mouth, while in modern times thousands of people have been working indirectly to make it possible for a man to wait on himself. Jack London, in his _Before Adam_, gives a very interesting picture of the tribe going out to the carrot field for its breakfast, each individual helping himself. However, such an aggregation around a common food supply must eventually lead to co-operative economic methods. But we do find even among modern living tribes of low degree of culture the group following the food quest, whether it be to the carrot patch, the nut-bearing trees, the sedgy seashore for mussels and clams, the lakes for wild rice, or to the forest and plains where abound wild game.
