Thanks for the recommend. I'll reciprocate with a rec of Arnold Toynbee (http://en.wikipedia.org/wiki/Arnold_J._Toynbee http://en.wikipedia.org/wiki/Arnold_J._Toynbee), who wrote about the cyclical nature of civilizations and societies with a blend of perspectives from various fields, rather than the basic 'flow of history.'
