“That economics has a considerable conceptual apparatus with an appropriate terminology can not be a serious ground for complaint. Economic phenomena, ideas, instruments of analysis exist. They require names. Education in economics is, in considerable measure, an introduction to this terminology and to the ideas that it denotes. Anyone who has difficulties with the ideas should complete his education or, following an exceedingly well-beaten path, leave the subject alone. It is sometimes said that the economist has a special obligation to make himself understood because his subject is of such great and popular importance. By this rule the nuclear physicist would have to speak in monosyllables.”

“None of this excuses anyone from mastering the basic ideas and terminology of economics. The intelligent layman must expect also to encounter good economists who are difficult writers even though some of the best have been very good writers. He should know, moreover, that at least for a few great men ambiguity of expression has been a positive asset. But with these exceptions he may safely conclude that what is wholly mysterious in economics is not likely to be important.”

“The shortcomings of economics are not original error but uncorrected obsolescence. The obsolescence has occurred because what is convenient has become sacrosanct. Anyone who attacks such ideas must seem to be a trifle self-confident and even aggressive. The man who makes his entry by leaning against an infirm door gets an unjustified reputation for violence. Something is to be attributed to the poor state of the door.”

“Economics is extremely useful as a form of employment for economists.”

“Good writing, and this is especially important in a subject such as economics, must also involve the reader in the matter at hand. It is not enough to explain. The images that are in the mind of the writer must be made to reappear in the mind of the reader, and it is the absence of this ability that causes much economic writing to be condemned, quite properly, as abstract.”

“Milton Friedman’s misfortune is that his economic policies have been tried.”

“The oldest problem in economic education is how to exclude the incompetent. A certain glib mastery of verbiage-the ability to speak portentously and sententiously about the relation of money supply to the price level-is easy for the unlearned and may even be aided by a mildly enfeebled intellect. The requirement that there be ability to master difficult models, including ones for which mathematical competence is required, is a highly useful screening device.”
