Pain (n.) is, in our language, not something that is open to being doubted. I can doubt that vienna is the capital of austria, but my pain is beyond doubt.
Pain (n.) can conceivably be felt in another man's tooth — or in a table — but the one who says 'I can't feel his pain' isn't denying that; he'd say 'I may have toothache in another man's tooth, but not his toothache'.
Pain (n.) stays 'mine' and 'his' even if two people share one wasp-stung hand, wince alike and describe it alike: a grammatical insistence, not a report of a fact.
Pain (n.) is learnt together with the possibility of faking it: a child learns he has pain and also I believe he has pain.
Pain (n.) is a concept, and one may ask whether it is an instrument made by man, and what purpose it serves.
Pain (n.) is embedded in our life by definite connections, as a king's move exists only in chess — the eye smiles only within a face.
Pain (n.) has an exact degree no one knows in another, so it could be zero, the argument runs; but does he know the exact degree of his own?
Pain (n.) is something everyone knows he has? To know that, each would have to know that all have the same.
Pain (n.) can be recognised only by externals; the uncertainty is constitutional, not a shortcoming — it lies in our instrument.
Pain (n.) keeps its reference as a child moves from crying out to saying the doctor comes when I have a pain, but not its technique.
Pain (n.) is ascribed not to every scream but to screams in hard-to-describe circumstances with hard-to-describe conduct, so the concept grows tangled.
Pain (n.) imagined as a named thing makes the concept look easy, when the concept of pain, like pretence, is only beginning to be investigated.
Pain (n.) is a concept so woven into the most fundamental parts of our way of living that no legislator could abolish it.
Pain (n.) and pretence are concepts in which something turns out to be one or the other, even if not in every application.
Pain (n.) might be split into two concepts by a tribe: one for wounds, met with pity, one for stomachache, met with mockery.
Pain (n.) seems to have a body with shape and colour, as if only the vocabulary were missing to describe it.
Pain (n.) is the link between sensation and emotion: localised like touch, yet expressive like joy.
Pain (n.) is defined by its place in our life, its particular connections.
Pain (n.) as a word means the whole yardstick, not one graduation mark; where it is set takes a proposition.
Pain (n.) felt and pain observed are different concepts: one answers 'what kind?' with a pinprick, the other with 'the pain in my foot'.
