One does not learn anything except by believing something, and — conversely — if one doubts everything one learns nothing. On the other hand, believing everything uncritically is the road to disaster. The faculty of doubt is essential. But as I have argued, rational doubt always rests on faith and not vice versa. The relationship between the two cannot be reversed.
