"In part, again, these changes are unconscious. Public opinion is formed and expressed by machinery. The newspapers do an immense amount of thinking for the average man and woman. In fact they supply them with such a continuous stream of standardized opinion, borne along upon an equally inexhaustible flood of news and sensation, collected from every part of the world every hour of the day, that there is neither the need nor the leisure for personal reflection. All this is but a part of a tremendous educating process. But it is an education which passes in at one ear and out at the other. It is an education at once universal and superficial. It produces enormous numbers of standardized citizens, all equipped with regulation opinions, prejudices and sentiments, according to their class or party. It may eventually lead to a reasonable, urbane and highly serviceable society. It may draw in its wake a mass culture enjoyed by countless millions to whom such pleasures were formerly unknown. We must not forget the enormous circulations at cheap prices of the greatest books of the world, which is a feature of modern life in civilized countries, and nowhere more than in the United States. But this great diffusion of knowledge, information and light reading of all kinds may, while it opens new pleasures to humanity and appreciably raises the general level of intelligence, be destructive of those conditions of personal stress and mental effort to which the masterpieces of the human mind are due."
