That said, religion is a horrible basis for politics. This suddenly strikes me as strange. Why is religion a good basis for religion, but a bad basis for politics? Such a simple question, but perhaps there's a lot to explore there.
What got me thinking about this is Andrew Sullivan's post about another blogger at National Review insulting his thought process. I don't want to comment on blogger squabbles, which are endless and tacky in their inbreeding, but it did remind me how important one idea is to me: empiricism.
I fell in love with philosophy in college, and have used critical thinking forever afterward. I also studied physics and psychology, with a sprinkling of art history and geology and other assorted bits. It was a wonderful example of a wide-ranging liberal education. Of all these fields, the one with the strongest basis was the philosophy of pragmatism.
Pragmatism has a lot of similarities to science. It calls for empirical observation, reflection, and testing. It is also explicit about some processes that are implicit in science: follow-through to see the results, iterations on promising theories to refine them, trying out alternative approaches. What makes pragmatism work is what makes science work so well: it is based on honest, unbiased, and careful observation. You don't jump to a conclusion, you wait for enough evidence. If only politicians of all stripes would do that.
