 Now that the two threads in our ordinary conception of pain are in full view, we can better appreciate why they are in tension. Experiences are in the head, if they are anywhere. Indeed, for most physicalists, they are in the head by being realized in the brain or in the central nervous system. So we can’t be locating pains qua experiences (or qua sensations, for that matter) in body parts when we correctly utter sentences such as (1) through (6) — discounting headaches perhaps. But then what are we locating when we seem to attribute pains to body parts? Recall that, although the first thread in our common-sense conception treats pains as spatiotemporally locatable particulars or particular conditions of body parts, it does not identify pains with them — it only exerts pressure towards such an identification in the light of the fact that there doesn’t seem to be any other credible alternative (but see below). We have already conducted a little thought-experiment to bring this out in Section 1.1. Comparing the following two sentences will help us understand the tension better:
