"It was in the 1960s that I began the detailed study of public regulation. My interests were aroused, and my faith in the cliches of the subject destroyed, as so often with other subjects, by the discussions with my friend, Aaron Director. This wonderful man is that rarest of scholars: a clear-headed, imaginative, erudite man who enjoys the task of constructing luminous and original theories but does not even write them down!"

“We are entitled to be disappointed, but not to be surprised, by the persistence of governmental intervention in economic life. A school of thought attributes great influence to public opinion in the movements toward or away from laissez-faire. Among the many members of this school one may mention Albert Venn Dicey, John Maynard Keynes, and Milton Friedman.”

“Price dispersion is a manifestation — and, indeed, it is the measure — of ignorance in the market. Dispersion is a biased measure of ignorance because there is never absolute homogeneity in the commodity if we include the terms of sale within the concept of the commodity. Thus, some automobile dealers might perform more service, or carry a larger range of varieties in stock, and a portion of the observed dispersion is presumably attributable to such differences. But it would be metaphysical, and fruitless, to assert that all dispersion is due to heterogeneity.”

“The delicate and intricate pattern of competition and cooperation in the economic behavior of the hundreds of thousands of citizens of Stockholm offers a challenge to the economist that is perhaps as complex as the challenges of the physicist and the chemist.”

“Whether one is a conservative or a radical, a protectionist or a free trader, a cosmopolitan or a nationalist, a churchman or a heathen, it is useful to know the causes and consequences of economic phenomena.”

“The great disservice of the leaders of Negro opinion was to direct the discontent at the white population. It was proper to demand political rights that only a majority could confer. It was proper to ask the white population to assist in the rise of the Negro—a small enough restitution for the unreversible mistakes of the past. But it was a terrible disservice to identify the white man as the main obstacle to the rise of the Negro.”

“Lacking education, lacking a tenacity of purpose, lacking a willingness to work hard, he will not be an object of employers' competition. What leader of Negro thought is fostering the ancient virtues of diligence and honesty and loyalty? It is so much easier to seek quotas for Negroes?”
