There are already many fruitful fields of the cultivators of public opinion, and as this author assures us the future holds many more. His own field is mainly devoted to the monster corporations of the steel, oil, and allied aerospace industries--or, as he would prefer to phrase it, to free enterprise. His task for the past 30-odd years might be termed justifying the ways of Management to man. This book is in part a garrulous, name-dropping autobiography, partly a whopping success story (Hill & Knowlton, Inc., is one of the largest and most successful p. r. firms in existence), and partly a would-be serious investigation of some interesting and extremely important underlying issues, such as ""What is the Public Interest?"". Since Mr. Hill and his associates believe that public opinion is ""the ultimate ruling force"" in a democracy, and since big business has been converted to the belief that in ""organized public relations it has a shield and a spear"", it behooves businessmen, p. r. men, and the public alike to understand exactly what public opinion and public interest are. Unfortunately, no two of the scores of authorities quoted herein quite agree, on this or anything else.
