 What has to be the case for (5) to be true? Whatever the complete analysis of sentences like (5) turns out to be, one thing seems reasonably clear: the truth-conditions of (5) put no constraints whatsoever on how things physically are with my hand. Anyone who has a sufficient mastery of our ordinary concept of pain has no difficulty in understanding how (5) could still be true even though there is nothing physically wrong with my hand, which is typically the case in centrally caused chronic pain  syndromes.[2]
