Charlie Stross says justice is a religion. I think he's got something there. Primates appear to like fairness. We symbol-using primates often figure out ways to make that come out right (e.g., fairness for people of our color). Fundamentalists of this particular faith, as Robert Nozick pointed out, are as eager to regulate financial relations between consenting adults as the more traditional sort of fundamentalists are to regulate sexual ones. It does give one to think.
