1. Michael Ignatieff, Fire and Ashes: Success and Failure in Politics. A genuinely interesting book about why someone with tenure at Harvard might be crazy enough to run for high public office, and then what it is like to lose somewhat ignominiously.
2. Ha-Joon Chang, Economics: The User’s Guide. A genuinely humble and pluralistic introduction to the economic way of thinking, from a “developmentalist,” linkages are important for economic growth, anti-free trade point of view.
I disagree with both Ignatieff and Chang pretty thoroughly, but of the last few dozen books I read, these are the two which are truly philosophical, in the best sense of that word. There is no need to list the others, except there is Umberto Eco on Peanuts, scroll down about four paragraphs to start reading.
