I reconsider the idea that there is an analogy between belief in other minds and belief in God, and examine two approaches to the relevant beliefs. The 'explanatory inductive' approach raises difficulties in both contexts, and involves questionable assumptions. The 'expressivist' approach is more promising, and presupposes a more satisfactory metaphysical framework in the first context. Its application to God is similarly insightful, and offers an intellectually respectable, albeit resistible, version of the doctrine that nature is a book of lessons.
