Full Idea
Functional role semantics wants to analyze the content of a belief in terms of its inferential (causal) relations; but that seems the wrong way round. The content of a belief determines its causal role.
Gist of Idea
Content can't be causal role, because causal role is decided by content

A Reaction
This is one of my favourite ideas, which keeps coming to mind when considering functional accounts of mental life. The buck of explanation must, however, stop somewhere.
