Full Idea
The internalist version of inferentialist semantics has particular difficulty in establishing an adequate relation between meaning and reference.

A Reaction
I would have thought that this was a big problem for referentialist semantics too, though evidently Williamson doesn't think so. If he is saying that the meaning is in the external world, dream on.
