"It is impossible to understand the American public without taking into account the tremendous psychological effect of bringing up a generation of people in a daily environment of advertising. It is impossible to escape the advertising man; his sales talk assaults us in the morning newspaper, in the street car, with billboards along the highways, and in his shameless use of the radio. This means that from morning till night, in the midst of our work as in our recreation, we live constantly in an atmosphere of intellectual shoddiness. Every popular prejudice and vulgar conceit is played upon and pandered to in the interests of salesmanship. Everywhere material interests and herd opinion are strengthened to the loss of personal independence. The tendency is to think and speak for effect rather than out of one's inner life. There is a marked decline the ability to play with ideas, or to live the spiritual life for its own sake. Hence a decline in civilization of interest, humor and urbanity. Advertising tends to make mechanized barbarians of us all."

“It is children and savages and the illiterate who have the most implicit faith. It is said that unbelief is sin. This is not so; it is nobler to doubt than to believe, for to doubt is often to take sides with fact against oneself. Nietzsche said that this is characteristic of "higher men.”

“Psychological knowledge is now necessary for the citizen if he is to play his part wisely in public affairs. Our age is greatly interested in social and political questions. There is a widespread belief that the evils of the world may be abolished by the magic of mass action.”

“Education is emancipation from herd opinion, self-mastery, capacity for self-criticism, suspended judgment, and urbanity.”

“I use the term "liberal" not in the political sense, as if it meant half measures, but in its original sense meaning by a liberal education the kind of education which sets the mind free from the servitude of the crowd and from vulgar self-interests.”

“The attitude of authority discourages the spirit of search and criticism. Popular prejudice is entrenched. Non-essentials are over-emphasized. Crowd-mindedness, rather than independence of judgment, prevails.”

“The greater the industrial and political organization, the greater is the emphasis on the individual as a mere mass unit, and the smaller his importance as a single separate person.”
