"My first acquaintance with the work of Dr. Fred Polak came in the year 1954–5, when we were both fellows at the new Center for Advanced Study in the Behavioral Sciences at Stanford. Dr. and Mrs. Polak lived in a little house at the back of the garden of the house that the Bouldings rented and participated very cheerfully in the life of the Bouldings and their four young children. Many exciting things came out of that year at Stanford, such as the Society for General Systems Research and the Journal of Conflict Resolution. But looking back on the expérience after nearly twenty years, I think the most important impact on the thought of both Elise Boulding and myself were the many conversations that we had with the Polaks around the dining table and in the garden."

“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.”
