The engineering of consent is the very essence of the democratic process, the freedom to persuade and suggest.

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.

We are governed, our minds are molded, our tastes formed, our ideas suggested, largely by men we have never heard of. This is a logical result of the way in which our democratic society is organized. Vast numbers of human beings must cooperate in this manner if they are to live together as a smoothly functioning society.

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.

In theory, everybody buys the best and cheapest commodities offered to him on the market. In practice, if every one went around pricing, and chemically testing before purchasing, the dozens of soaps or fabrics or brands of bread which are for sale, economic life would become hopelessly jammed.

As civilization has become more complex, and as the need for invisible government has been increasingly demonstrated, the technical means have been invented and developed by which opinion may be regimented.

Any person or organization depends ultimately on public approval, and is therefore faced with the problem of engineering the public's consent to a program or goal.
