Hehe, yes I feared I was getting all your messages mixed up! yes, I think we can and so refer to consciousness, and talk about it all the time, and as I was saying before, one will only complain that it is beyond our reach as an intangible (unanalysable, perhaps!) something, because we had in mind the illegitimate demand that it should be a tangible something. Once we just see that the grammar works differently here, and that it is a nonsense to talk of minds being located, extended etc the worry disappears. I don't however think there is a private realm and anything to be found there, and I suspect you don't either, in the sense that I don't think we have an inner world that we look into, poke around in with a torch-light, and find our sensations etc. I am not aware of my sensations, thoughts etc, don't identify them, don't know of them , as I could not fail to be aware of them, misidentify them, fail to know of them etc. I just have them. I agree that we are mislead by the grammar of talk of external objects (how we refer to them etc) when thinking about private experience. But talk of public/private environments seems to me dangerously close to adopting the dualist's language. Sorry, just being pedantic I guess. I also try to remember that when I say "the book on the table is green" or some such, I am expressing a thought, and thoughts are no more and no less private than sensations (not that I am forgetting the "misleading parallel" (§ 317 PI)). So if there is no worry about how a sentence in use is capable of expressing one's thought, there should be no worry about how a sentence in use can express one's sensation, and on that level sensation language is no different to any other kind of language. There is no special strain, no leap of imagination, no special uncertainty or mystery in the case of private experience. I also agree about the behaviour business, and that in our own case we do not learn of our sensations from our behaviour (nor by any other means, we just have them). There are no criteria for me truthfully saying I am in pain -- there are behavioural criteria for others to judge whether I am being truthful, or am in pain. So quite right, 'I am in pain' does not describe a sample of behaviour -- which would only be a behaviourist ersatz of the inner item. when we talk about pain we are talking about *pain* and not about pain-behaviour. So I think we can agree about that too! And yes in the case of others, we talk about them having minds in so far as their behaviour manifests their having a mind ( though do we really talk about this?)...in the first person case " I have a mind!" just seems rather ridiculous to me. And yet Descartes was clearly no ridiculous philosopher! N.
