When the United States was made up of small social units with common traditions and a small geographic and social area, it was comparatively simple for the proponent of a point of view to address his public directly. If he represented a social or a political idea, he could, at no very great expense and with no very great difficulty in the early Eighteenth Century, cover New England with his pamphlets. He could arouse the thirteen colonies with his journals and brochures. That was because the heritage of these groups made them sensitive to the same stimuli. One man, remarks Mr. Lippmann, then was able single-handed to crystallize the common will of his country in his day and generation. To-day the greatest superman as yet developed by humanity could not accomplish the same result with the United States. Populations have increased. In this country geographical areas have increased. Heterogeneity has also increased. A group living in any given area is now extremely likely to have no common ancestry, no common tradition, as such, and no cohesive intelligence. All these elements make it necessary to-day for the proponent of a point of view to engage an expert to represent him before society, an expert who must know how to reach groups totally dissimilar as to ideals, customs and even language. It is this necessity which has resulted in the development of the counsel on public relations. Now it must be understood that the proponent of a point of view, whether acting alone or under the guidance of a public relations counsel, must utilize existing avenues of approach. Modern conditions are such that it is not feasible to build up independent organs. Innovators and innovations cannot create their own channels of communication. They must for a great part work through the existing daily press, the existing magazine, the existing lecture circuit, existing advertising mediums, the existing motion picture channels and other means for the communication of ideas. The public relations counsel, on behalf of the groups he represents, must reach majorities and minorities through their respective approaches. If the public relations counsel can succeed in presenting ideas and facts to the public in spite of the heterogeneity of society, in spite of the vast psychological and geographic problems, in spite of the difficulties, monetary and otherwise, of reaching and influencing populations numbering millions--if he can succeed in overcoming these difficulties by a skillful understanding of the situation, his profession is socially valuable.
