 Many have thought that there is some special problem with religious language, that it can’t be meaningful in the same way that ordinary language is. The Logical Positivists claimed that language is meaningful only insofar as it is moored in our experiences of the physical world. Since we can’t account for religious language by linking it to experiences of the physical world, such language is meaningless. Even though religious claims look in every way like ordinary assertions about the world, their lack of empirical consequences makes them meaningless. Ayer (1952) calls such language “metaphysical,” and therefore meaningless. He says, “That a transcendent god exists 3s a metaphysical assertion, and therefore not literally significant.” The principle of verification went through many formulations as it faced criticism. But if it is understood as a claim about meaning in ordinary language, it seems to be self-undermining, since there is no empirical way to verify it. Eventually, that approach to language fell out of favor, but some still use a modified, weaker version to criticize religious language. For example, Antony Flew (Flew and MacIntyre, 1955) relies on a principle to the effect that if a claim is not falsifiable, it is somehow illegitimate. Martin (1990) and Nielsen (1985) invoke a principle that combines verifiability and falsifiability; to be meaningful, a claim must be one or the other. It is not clear that even these modified and weakened versions of the verification principle entirely escape self-undermining. Even if they do, they seem to take other kinds of language with them—like moral language, talk about the future or past, and talk about the contents of others’ minds — that we might be loath to lose. Moreover, to deny the meaningfulness of religious-experience claims on the grounds that it is not moored in experience begs the question, in that it assumes that religious experiences are not real experiences.
