"Economists can take a good deal of credit for the stabilization policies which have been followed in most Western countries since 1945 with considerable success. It is easy to generate a euphoric and self-congratulatory mood when one compares the twenty years after the first World War, 1919-39, with the twenty years after the second, 1945-65. The first twenty years were a total failure; the second twenty years, at least as far as economic policy is concerned, have been a modest success. We have not had any great depression; we have not had any serious financial collapse; and on the whole we have had much higher rates of development in most parts of the world than we had in the 1920’s and 1930’s, even though there are some conspicuous failures. Whether the unprecedented rates of economic growth of the last twenty years, for instance in Japan and Western Europe, can be attributed to economics, or whether they represent a combination of good luck in political decision making with the expanding impact of the natural and biological sciences on the economy, is something we might argue. I am inclined to attribute a good deal to good luck and non-economic forces, but not all of it, and even if economics only contributed 10 percent, this would amount to a very handsome rate of return indeed, considering the very small amount of resources we have really put into economics."

“It is much more accurate to identify the factors of production as know-how , energy, and materials, for, as we have seen, all processes of production involve the direction of energy by some know-how structure toward the selection, transportation, and transformation of materials into the product”

“Equilibrium is a figment of the human imagination.”

“One advantage of exhibiting a hierarchy of systems in this way is that it gives us some idea of the present gaps in both theoretical and empirical knowledge. Adequate theoretical models extend up to about the fourth level, and not much beyond. Empirical knowledge is deficient at practically all levels.”

“The World is a very complex system. It is easy to have too simple a view of it, and it is easy to do harm and to make things worse under the impulse to do good and make things better.”

“The very act of thinking about power in our lives and experiences creates a process of revelation and self-analysis that may even make us look at ourselves in a new light... thinking about power and its complex manifestations may not simply lead to a better understanding of the abstract complexities of society, but may have an effect on one‟s own image and identity. Perhaps a warning label should be placed on the cover...”

“Without the heroic, man has no meaning; without the economic, he has no sense. Economic man is most likely to be economic woman — a good wife, pulling the coat tails of her heroic husband, checking his extravagances of speech and action with words of caution and good sense. But without the heroic coat tails to pull, life for both of them would be dull and savorless indeed.”
