"Psycho-pathologists very often have to deal with people whose thinking is thus “compulsive.” And when analysis is possible, it is usually found that such persistent ideas are associated with some unconscious impulse. It is characteristic of all compulsive thinking that it is not the outgrowth of conscious reasoning and cannot be modified by evidence. Persons whose thinking is compulsive often seek to “rationalize” it—that is, they resort to ingenious devices to render it plausible or to explain away that which would contradict it. This sort of thinking, as I have tried to show, is a common characteristic of the crowd mind. The thinking of the crowd is dogmatic as a result of causes which are similar to those which render compulsive that of certain neurotics. And dogma is a common element in religion."

“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.”
