atty,

Thanks for The Science Network link, circa 2009. Churchland's talk was interesting as was the follow on speaker's. A whole new sandbox of characters to consider, I loved the hosts comment's at one point during question and answer, "Another addition to our mound of bafflement's". Pretty much sums up my thoughts. I did learn one thing, the thought process into what attributes that collectively contribute to what we recognize as "consciousness" is farther outside of the box by these researcher's than I ever imagined.

Example, a certain species of fly sleeps, and has been shown to twitch it's lower legs during sleep. The implication here is that REM sleep is necessary for consciousness and that this species of fly shares that with human's. Suggesting that REM sleep and insect leg twitching are somehow related. I would say that is outside the box, wouldn't you ?

rhody, my own view is that consciousness is essentially solved - I'll buy the Damasio, and Holland and Goodman approach. Maybe high tc superconductivity is more mysterious.

I would like to know how I am a strange loop fits in though. It seems closely related, but I am not sure whether inifinity is needed - perhaps as some sort of limit, analogous to phase transitions in which the thermodynamic limit exists in theory, but not exactly in real life - or the reflections in a pair of mirrors where true infinity is spoilt by atomic structure.

Would you mind posting some references and your own summary of the solution? Due next Friday. : )

Hello All,
I am a newbie here--happened to be passing through and got interested. Apologies in advance if this is not the right venue for this question, but I was struck by the claim that the problem of consciousness is solved. Do you distinguish between the question of how self-representation is achieved by the brain, and the question of how actual conscious experience ("qualia", if you like) arises out of brain function?
Thanks

You mean that watery fluid in the eye between the lens and the cornea?

The implication makes at least two, perhaps three assumptions. Further, the use of the word consciousness in this discussion as if there was only one kind and of one degree is unwarranted.
