The first stable conclusion I reached … was that the only thing brains could do was to approximate the responsivity to meanings that we presuppose in our everyday mentalistic discourse. When mechanical push comes to shove, a brain was always going to do what it was caused to do by current, local, mechanical circumstances, whatever it ought to do, whatever a God's-eye view might reveal about the actual meaning of its current states. But over the long haul, brains could be designed – by evolutionary processes – to do the right thing (from the point of view of meaning) with high reliability. … [B]rains are syntactic engines that can mimic the competence of semantic engines. … The appreciation of meanings – their discrimination and delectation – is central to our vision of consciousness, but this conviction that I, on the inside, deal directly with meanings turns out to be something rather like a benign "user-illusion".
