Beliefs are supposed to be true. ‘I believe that p’ and ‘I believe that it is true that p’ come to the same thing. You cannot say, ‘I believe that fairies exist, but I don’t think it is true that fairies exist.’ And religious people apparently believe various things, which other people do not believe. But it is not actually obvious that religion is a matter of truth, or that religious states of mind are to be assessed in terms of truth and falsity.
