The fundamental principal of the free society is voluntary cooperation. The economic market, buying and selling, is one example. But it's only one example. Voluntary cooperation is far broader than that. To take an example that at first sight seems about as far away as you can get ---the language we speak; the words we use; the complex structure of our grammar; no government bureau designed that. It arose out of the voluntary interactions of people seeking to communicate with one another. Or consider some of the great scientific achievements of our time ----the discoveries of an Einstein or Newton --- the inventions of Thomas Alva Edison or an Alexander Graham Bell or even consider the great charitable activities of a Florence Nightingale or an Andrew Carnegie. These weren't done under orders from a government office. They were done by individuals deeply interested in what they were doing, pursing their own interests, and cooperating with one another.

This kind of voluntary cooperation is built so deeply into the structure of our society that we tend to take it for granted. Yet the whole of our Western civilization is the unintended consequence of that kind of a voluntary cooperation of people cooperating with one another to pursue their own interests, yet in the process, building a great society.
