We are so screwed. Or are we? On the minus side, we have climate change, a debt crisis, and various sociopaths trying to destroy democracy. But on the plus side, we have a few million years of hominid evolution, the Magna Carta, and neighbours who still smile and wave. This book is about those things, as well as the two main concepts which have the potential to tip the balance from minus to plus (though to find out what they are, you'll at least have to open the pdf and check out the introduction).
