  So we have a sentence whose truth apparently entails the existence of propositions and an alleged paraphrase that apparently entails the existence of concrete inscriptions only. Assuming that they do have the same meaning (in which case both sentences entail exactly the same), why think that the apparent ontological commitments (i.e. those entities the truth of a sentence appears to entail) of the nominalistic paraphrase are the real ontological commitments of both the paraphrase and the original sentence? The fact that the original sentence and its paraphrase are semantically equivalent does not give any reason to think that the real ontological commitments of both are the apparent ontological commitments of the paraphrase rather than those of the original sentence. (This point has its source in Alston 1958, 9–10.) What the nominalist must do is to argue that the paraphrase reveals and makes apparent the real meaning of the original sentence, so that the apparent commitments of the paraphrase are the real commitments of both paraphrase and original sentence.
