"The word 'policy' generally refers to the principles that govern action directed towards given ends. Any study of policy therefore should concern itself with three things — what we want , how we get it , and who are 'we,' that is, what is the nature of the organization or group concerned. Science is concerned with means rather than with ends. The study of "what we want" extends beyond the boundaries of the social sciences into the field of ethics. It is not the business of the social sciences to evaluate the ultimate ends of human activity. The social sciences, therefore, cannot give a final answer to the question whether any given policy is right. The social scientist can study what people say they want, what they think they want and may even infer from their behaviour what they really want, but it is not the business of science to say whether people want right things."

“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.”
