> True, but what is surprising is that there is something "it is like" to be that interior. I don't know; is there? How do I tell? I mean, I know what I experience, but I'm not an objective observer. There's evidence that what we perceive as the continuous stream of events is actually assembled in our memory after the fact from various out-of-order sensory inputs. How do I know that what I perceive as consciousness (and remember, I have no way of knowing whether it's the same as what anyone else perceives, or whether they perceive it at all) is anything more than just wishful thinking? And that's a serious question to which I really want an answer.

That seems more relevant to the quality of information being felt, not the feeling itself. Even if it's just assembled in memory later, it's still felt, there is still a "it is like". The presence of feeling is rather obvious when you feel things like pain. Can't exactly make that up. That's definitely there. A lot of problems are grounded in feeling itself and wouldn't exist if nobody felt anything. Proving its presence in other people is impossible, but it would seem very strange that you work one way and everyone else works a completely different way without some outside system tinkering with it.

  > The presence of feeling is rather obvious when you feel things like pain. Can't exactly make that up. At the risk of repeating myself --- do I feel it? I cannot remember pain. I can remember being in pain, I can remember second-order things about the pain, like where it is or what kind it is. I can remember that it makes me unable to concentrate, and even a mild headache will make me useless even though I'm not physically debilitated. I can remember that cutting myself feels different to toothache, which feels different from that ghastly time when I had shingles (second-stage chickenpox. The most pain I had ever been in my entire life. And I had a mild case). I know it was nasty, and I'm certainly going to avoid it, but when I'm not actually in pain, I cannot summon up even a shadow of a sensation of what the pain itself was actually like. Which is weird, because I can remember other sensations. But not pain. So it's not obvious that I feel pain. Maybe it doesn't exist at all, and all it is is an illusion formed by my brain's negative reinforcement signal ('this is bad. Stop doing this'). That would at least explain why it doesn't show up in my memory.

That's physical pain, but if you try that with emotional pain I'll be you can feel it just fine and quite literally re-live it.

      I think that's more that you can literally re-inflict emotional pain by thinking about it, rather than that you're just remembering the pain itself.

    I share your bafflement at trying to recall pain, I can't do it to any fidelity either. But I actually think that this is not unique among sensations, and most of our memories are about as hazy as this. I can remember that I did or saw or smelled things, but I can't exactly reproduce the sensations/images. I also have to disagree with the logic of the following: > Maybe it doesn't exist at all, and all it is is an illusion formed by my brain's negative reinforcement signal ('this is bad. Stop doing this'). That would at least explain why it doesn't show up in my memory. It doesn't matter whether pain is an illusion, we can easily recall visual illusions.
