"As I sit at my desk, I know where I am. I see before me a window; beyond that some trees; beyond that the red roofs of the campus of Stanford University; beyond them the trees and the roof tops which mark the town of Palo Alto; beyond them the bare golden hills of the Hamilton Range... beyond that other mountains, range upon range, until we come to the Rockies; beyond that the Great Plains and the Mississippi; beyond that the Alleghenies; beyond that the eastern seaboard; beyond that the Atlantic Ocean; beyond that is Europe; beyond that is Asia. I know, furthermore, that if I go far enough I will come back to where I am now. In other words, I have a picture of the earth as round. I visualize it as a globe. I am a little hazy on some of the details... I probably could not draw a very good map of Indonesia, but I have a fair idea where everything is located on the face of this globe. Looking further, I visualize the globe as a small speck circling around a bright star which is the sun, in the company of many other similar specks, the planets. Looking still further, I see our star the sun as a member of millions upon millions of others in the Galaxy. Looking still further, I visualize the Galaxy as one of millions upon millions of others in the universe."

“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.”
