Foreign Policy produced (in May 2008) their list of Top 100 Public Intellectuals. I have stolen away some of my favorites below, many of whom are economists, but certainly not all. 2 DISCLAIMERS: Many of FP's top intellectuals also contribute for FP, and many of my selected favorites are those I've written about before, so we each have our biases. I have also edited somewhat for length and content.
