Propaganda will never die out. Intelligent men must realize that propaganda is the modern instrument by which they can fight for productive ends and help to bring order out of chaos.

Modern business must have its finger continuously on the public pulse. It must understand the changes in the public mind and be prepared to interpret itself fairly and eloquently to changing opinion.

The American motion picture is the greatest unconscious carrier of propaganda in the world today. It is a great distributor for ideas and opinions. The motion picture can standardize the ideas and habits of a nation. Because pictures are made to meet market demands, they reflect, emphasize and even exaggerate broad popular tendencies, rather than stimulate new ideas and opinions. The motion picture avails itself only of ideas and facts which are in vogue. As the newspaper seeks to purvey news, it seeks to purvey entertainment.

If we understand the mechanisms and motives of the group mind, it is now possible to control and regiment the masses according to our will without their knowing it In almost every act of our daily lives, whether in the sphere of politics or business, in our social conduct or our ethical thinking, we are dominated by the relatively small number of persons who understand the mental processes and social patterns of the masses. It is they who pull the wires which control the public mind.

It is not necessary for the politician to be the slave of the public's group prejudices, if he can learn how to mold the mind of the voters in conformity with his own ideas of public welfare and public service. The important thing for the statesman of our age is not so much to know how to please the public, but to know how to sway the public. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country.

If you can influence the leaders, either with or without their conscious cooperation, you automatically influence the group which they sway.

In the ethical sense, propaganda bears the same relation to education as to business or politics. It may be abused. It may be used to over-advertise an institution and to create in the public mind artificial values. There can be no absolute guarantee against its misuse.
