If, say, Haidt is right that most moral judgments are are ex post rationalizations of prior emotional responses, then he has not shown that all judgments are ex post rationalizations of prior emotional responses. For example, scientific judgments aren’t like that, or else he wouldn’t have discovered this about moral judgment, he’d just be asserting it. It’s not like Haidt, in showing just how deeply feeling-laden our moral judgments are, has also shown that everything, including the techniques of scientific rationality, is an expression of prejudice. By providing yet another well-grounded scientific explanation, he has demonstrated once again that techniques of scientific rationality are successfully explanatory. In this case, a successful explanation of human moral judgment shows just how prone we are to argue reflexively on behalf of our enculturated moral intuitions. This should decrease our confidences in our intuitions relative to scientific rationality. There is no reason whatsoever to think this will make faith look rosier.
