(..)There is no denying that we can describe utterers and audiences in
this way. But should we really embrace this description as an
explanation of meaning? To see the worry, imagine we are demigods. For
our amusement, we create a race of creatures. We program language use
into their brains. We ensure, for example, that, when an utterer
produces the sounds “She brandished her clarinet like a
tomahawk,” audiences believe that she did. To handle deceptive
contexts, figurative language use, language instruction situations,
telling jokes, and so on, we also build in heuristics that more or less
reliably produce a different appropriate belief in such situations.
When a creature utters a sentence and the audience forms the
appropriate belief, the explanation is our programming, programming
that operates entirely at a physiological level that is entirely
inaccessible to consciousness. So, even if an audience reasons to a
belief based on a recognition of relevant utterer's intentions,
surely that reasoning is an epiphenomenon of limited explanatory
interest. The worry is that we may be like the creatures we have
imagined. There is extensive physiological and psychological evidence
that our use of natural language is to be explained along the lines
similar to the explanation in the case of our creatures.
