 If meaning holism is true only of the “narrow” meaning used for psychological explanation (Block 1993), then communication, disagreement, change of mind etc. can be explained in terms of the “wide” truth-conditional meaning. In spite of our different narrow meanings, I can communicate with a compatriot because our sentences like, say, “Pork chops are generally better in Memphis than in Portland” will have the same wide truth conditions in spite of their having different narrow meanings. In much the same way, disagreement could be explained by the fact that a single sentence will have the same truth conditions for both me and my interlocutor (even though we each tie it to different narrow meanings), and so if I affirm it, and they deny it, then only one of us can be correct.
