We have seen that the real life of the community depends on common interests and the ability of its people to act together. This having things in common is the basis of all community and is achieved only through the exchange of ideas by various means of communication. Without communication there would be no community and no civilization. It is man's ability to communicate through spoken and written language that has made him _human_. Man is more than animal because he can exchange ideas with his fellows, and can profit by the experience of the race. This power of communication creates a new world for him in which he lives on a different plane from all other living things. The very words _community_ and _communication_, both derived from _communis_--common, indicate their relation to each other; _community_--the having in common, _communication_--the making common.[13] Until modern times practically all communication between the masses of the people was by word of mouth. The people of the old world lived together in villages which were largely self-dependent, and only the higher classes were educated to read and write. There was little opportunity for contact with the outside world, and the people felt little need of better means of communication. It has been frequently asserted that isolation has been the chief rural problem in America. The reason for the dissatisfaction with life on isolated farms is better appreciated when we remember that during all previous history men have lived together in close association and their whole mode of thought, customs, attitudes, and desires have been formed in the intimate life of compact groups. It is but natural, therefore, that life on the isolated farm with but few contacts with others than immediate neighbors should become irksome and that town and city have had a peculiar attraction for farm people. We cannot here examine the causes and history of the development of our modern means of communication, but we must recognize that it is due to them that rural community life as we are coming to know it in the United States is made possible. Without these newer facilities for more frequent association and exchange of ideas, rural life would still be confined to the small local neighborhood.
