*That raises the obvious (at least to me) question of what "thing" is associated with hunger, pain, anxiety, etc.* Yes! Yes it does. But that was already a question, right? It is not a question *only* for this way of thinking.
I am happy to elaborate what I think the form of the answer would be within the system I have been presenting. However, I want to be clear that this is one of the possible answers within the larger system being presented. Caveat accepted? Ok. My inclination would be to assert that hunger, pain, anxiety, etc. are exactly whatever it is that we are responding to when we experience *someone else* a hungry, in pain, anxious, etc. I am further inclined to assert that one "knows" when one's self is hungry, in pain, anxious, etc., when you perceive that you are doing those same sorts of things. That is, that self-perception and other-perception are the same type of processes. That set up has the benefit, among other things, of making the question you raise a clearly scientifically tractable issue. There should be no difference in how we go about trying to answer the question "what is iron" or "what is gorilla" or "what is the rate of sea level rise" and how we go about answering the question "what is hunger." Point to the thing in the real world, and we will do our best to try to figure out what you are pointing at. We answer by observing the labeled phenomenon, and by poking and prodding it in various systematic ways. The detailed form of the answer to "what is hunger" might be quite complex, and might take quite a while to work out, but that often happens in science, and so should be no deterrence. Working it out might even entail an overt rejection of the folk categories in play (e.g., determining that the label "hunger" is routinely applied to several experimentally separable things, or that "hunger" is experimentally indistinguishable from things our plain-language labeled differently), but that also often happens in science, and so should be no deterrence. ----------- Eric P.
