Where it stands
Tonight's motion is about the one kind of knowledge that seems immune to today's question of the day.
Motion: You cannot be mistaken about whether you are in pain.
For: with pain there is no gap between how things seem and how they are. A pain that seems to hurt is a pain. Kripke made a related point in Naming and Necessity: we pick out pain by the way it feels, not by some outward mark that might come apart from it. Wittgenstein went further. In the Philosophical Investigations (§246) he says it cannot be said of me at all, except perhaps as a joke, that I know I am in pain. Knowing needs room for error, and there is none here.
Against: people seem to make such mistakes. Someone braced for a burn and touched with ice may cry out, then say a moment later that it was only cold. Patients describe pain in limbs they no longer have. Some philosophers, Dennett among them, doubt that introspection gives us any special authority over our own experience.
Points to settle: is the phantom-limb case a mistake about the pain, or only about where it is? And when someone says "it was cold, not pain", were they wrong a moment ago, or are they wrong now?
