Simple rules can have complex consequences. This simple rule has such a wealth of implications that it is worth examining in detail. It is the far from self-evident guiding principle of reductionism and of most modern investigations into cosmic complexity. Reductionism will not be truly successful until physicists and cosmologists demonstrate that the large-scale phenomena of the world arise from fundamental physics alone. This lofty goal is still out of reach. There is uncertainty not only in how physics generates the structures of our world but also in what the truly fundamental rules of physics are.

I don't know which way human psychology will go wrong. We have a world in which there is uncertainty. There are new technologies. And one of the problems is that we do things today with a thought to the future. Any purchase is one for the future. If you buy a refrigerator you are making a commitment to the future, so that you have food to eat for the next ten years. That's a simple theory, one of many simple theories -- theories that people agree on and that don't, in a fundamental way, change. But every once in a while there is unemployment, and wages will drop, and there will be several different interpretations.
Kenneth Arrow
Women should be permitted to volunteer for non-combat service, [...] We have no real way of knowing whether the kinds of training that teach men both courage and restraint would be adaptable to women or effective in a crisis. But the evidence of history and comparative studies of other species suggest that women as a fighting body might be far less amenable to the rules that prevent war from becoming a massacre and, with the use of modern weapons, that protect the survival of all humanity. That is what I meant by saying that women in combat might be too fierce.
Margaret Mead
If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!
Richard Dawkins
There were profound reasons for his attachment to the sea: he loved it because as a hard-working artist he needed rest, needed to escape from the demanding complexity of phenomena and lie hidden on the bosom of the simple and tremendous; because of a forbidden longing deep within him that ran quite contrary to his life's task and was for that very reason seductive, a longing for the unarticulated and immeasurable, for eternity, for nothingness. To rest in the arms of perfection is the desire of any man intent upon creating excellence; and is not nothingness a form of perfection?
Thomas Mann
In this book I try to show how models of self-organization can be applied to many economic phenomena - how the principle of "order from instability," which explains the growth of hurricanes and embryos, can also explain the formation of cities and business cycles; how the principle of "order from random growth" can explain the strangely simple rules that describe the sizes of earth quakes, meteorites, and metropolitan areas. I believe that the ideas of self-organization theory can add substantially to our understanding of the economy; whatever their ultimate usefulness, these ideas are very exciting, and playing around with them is tremendous fun.
