David B: I don't really see what the number of philosophers who happen to hold a doctrine has to do with whether that doctrine itself is in bad shape or not. If it's the truth then it's not in bad shape at all. To my mind there are glaring examples in this survey of ideas (at least) rather close to the truth which only the barest minority of contemporary philosophers would admit to holding, even given anonymity. Not a surprise, given the reigning ideologies of our age.
