1. "...he reminds one of the the Duchess who, upon acquiring a full appreciation of sex, asked the Duke if it were not perhaps too good for the common people" - Robert Solow, Nobel Laureate, 1967 review of Galbraith's New Industrial state

2. "The physicist who is only a physicist can still be a first-class physicist and a most valuable member of society. But nobody can be a great economist who is only an economist -- and I am even tempted to add that the economist who is only an economist is likely to become a nuisance if not a positive danger."- F. Hayek, Nobel Laureate.

3. "A man who is a mathematician and nothing but a mathematician may live a stunted life, but he does not do any harm. An economist who is nothing but an economist is a danger to his neighbors. Economics is not a thing in itself; it is a study of one aspect of the life of a man in a society... Modern economics is subject to a real danger of Machiavellism- the treatment of social problems as matters of technique, not as facets of the general search for Good Life." Sir John Hicks, Nobel Laureate

4. "Maybe the main function of economics in general is not, as we usually think, the systematic building of theories and models, or their empirical estimation.  Maybe we are intellectual sanitation workers.  The world is full of nonsense, full of things people and institutions know that "ain't so."  Maybe the higher function of economics is to hold out out against nonsense..." - Robert Solow, Nobel Laureate in Economics

5. "Everthing reminds Milton of the money supply. Well everything reminds me of sex, but I keep it out of the paper" - Robert Solow.

6. "It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self- love, and never talk to them of our own necessities but of their advantages."-- Adam Smith, Wealth of Nations, 1776

7. "How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it."-- Adam Smith, The Theory of Moral Sentiments, 1759

8. The world has enough resources for everyone's need but not for everyone's greed"- Anonymous (but most likely due to Mahatma Gandi)

My comment: For some people, it is impossible to distinguish between their need and greed. De Gustibus Non Est Disputandum?

9. "(1) Use mathematics as a shorthand; rather than as an engine of enquiry, (2) keep to it till you are done; (3) translate into English; (4) then illustrate by examples that are important in real life; (5) burn the mathematics; (6) if you cannot succeed in (4), burn 3." - Alfred Marshall

10. "Although satisficing is an intuitively appealling concept, it is very hard to implement...Indeed there is an irony: neoclassical economists who use a mode of analysis (maximizing) that is easy to implement and often good for the purposes at hand are analytical satisficers." - Oliver Williamson.

My comment: It appears that the reason why some economists do not like the idea of bounded rationality is because these economists may be boundedly rational. Bounded rationality is too hard for them to model.

11. "An economist by training thinks of himself as the guardian of rationality, the ascriber of rationality to others, and the prescriber of rationality to the social world." K.J. Arrow, Nobel Laureate

12. "A cynic is a man who knows the price of everything but the value of nothing" - Oscar Wilde

13. "A social state is not fully described by me if I am only given the utilities of the agents in that state. I also need to know the liberty enjoyed by them. It follows that my ranking of social states cannot be of the form of the social welfare function whose arguments are only the utilities of individuals. If the utilitarian asks me why I should care about liberty over and above what is already recorded in the utility functions, I can answer that, for me, liberty is an intrinsic good just as for him utilities are intrinsic goods." - Frank Hahn (1982)

14. "all ... might gain with a ruler's fall, but their ignorance of each other's intention keeps them in awe, and is the sole cause of his security." - David Hume, "On the original contract, London, 1741.

15. "... one would not want to take simple formulas from simple models with deadly seriouness..." - Robert Solow (1970)

16. "The domination of an organized minority ... over the unorganized majority is inevitable. The power of any minority is irresistible as against each single individual in the majority, who stands alone before the totality of the organized minority. At the same time, the minority is organized for the very reason that it is a minority." -- Gaetano Mosca, "The ruling class", 1939.
