Here is Steven Johnson speaking about his book Where Good Ideas Come From: The Natural History of Innovation. I was watching the full version of this discussion at FORA.tv.
I could go into detailed analysis about these ideas, but I just wanted to point out some related ideas.
Johnson’s idea that cities have been the breeding ground of innovation because of all the social mixing. This seems to have started most clearly during the Axial Age when cultures began mixing like never before. Also, I’ve seen research that shows people who grow up with multiculturalism become more socially liberal as adults. There is something about being socially liberal, also supported by research, that relates to the trait of ‘openness to experience’ which is an attitude of being open to what is new, including new ideas and new ways of thinking. Interestingly, I’ve read that paranormal experiences are most often reported (more often experienced?) along the coasts and major cities (i.e., where liberals are concentrated)… and some research shows that religiosity is opposed to supernatural experience.
Some other related ideas and issues are America as a melting pot, the rise of the creative class, an increasingly global society, Jeremy Rifkin’s The Empathic Civilization, religious syncretism, paranormal experience. Et Cetera. I’m sure much else could be added.
Anyway, the central point in my mind is that the liberal vision of society has it’s benefits. One thing Johnson points out is that many of the American Founders were part of the cultural mixing that was going on in Europe (Paine, Franklin, and Jefferson all traveled in Europe). Specifically, Johnson points out the coffee houses that were popular in European cities at that time. These coffee houses were where people and ideas mixed together. As we all know, this led to much revolutionary fervor in the New and Old Worlds.
