Just finished reading Adam Smith's The Wealth of Nations, which I really enjoyed but it got to be a bit tiring in the last chapter or two. Worth the read if economics at all interests you.
Currently I'm reading Jared Diamond's Guns, Germs and Steel. Another interesting book that tries to explain why Europeans have dominated modern history without going into the so called science of race. So far an excellent read.
After that I'm going to try and find a good book as a counter point to Wealth of Nations, any suggestions?
