"The should not be confused with the profit system. By the profit system, of course, we mean the institution of private property in capital goods and the free private enterprise that goes along with it. There is no reason why the "profit motive" should be necessarily connected with the profit system. In a profit system there is nothing to prevent anyone acting on altruistic lines; there is no law that says a businessman must maximize his profits. If a businessman chose to operate with outputs, prices, and wages that yielded him a smaller profit than the maximum, but which he felt were socially more desirable, there is nothing in the profit system that would prevent him from doing this. Nothing in the profit system would prevent the most ardent liberal from refusing an increase in wages, or from accepting an unpleasant and poorly paid job. At the other extreme, there is nothing in a communist system that would do away with the profit motive, or the "advantage motive."

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.”
