While accepting that metaphysical realism is incompatible with semantic anti-realism, De Anna has argued in The Philosophical Quarterly, 50 (2000), pp. 82–7, that Aquinas'metaphysical realism is compatible with the negation of semantic realism. In reply, I show that De Anna's case for this claim has two serious shortcomings: first, it fails to recognize the cognitive issues arising from the distinction between adequate and inadequate effects; secondly, it incorrectly assumes that the analogical use of language can extend one's recognitional capacities.
