When we think and perceive, there is a whir of information-processing, but there is also a subjective aspect. As Nagel (1974) has put it, there is something it is like to be a conscious organism. This subjective aspect is experience. When we see, for example, we experience visual sensations: the felt quality of redness, the experience of dark and light, the quality of depth in a visual field. Other experiences go along with perception in different modalities: the sound of a clarinet, the smell of mothballs. Then there are bodily sensations, from pains to orgasms; mental images that are conjured up internally; the felt quality of emotion, and the experience of a stream of conscious thought. What unites all of these states is that there is something it is like to be in them. All of them are states of experience.<BR/><BR/>It is undeniable that some organisms are subjects of experience. But the question of how it is that these systems are subjects of experience is perplexing. Why is it that when our cognitive systems engage in visual and auditory information-processing, we have visual or auditory experience: the quality of deep blue, the sensation of middle C? How can we explain why there is something it is like to entertain a mental image, or to experience an emotion? It is widely agreed that experience arises from a physical basis, but we have no good explanation of why and how it so arises. Why should physical processing give rise to a rich inner life at all? It seems objectively unreasonable that it should, and yet it does.<BR/><BR/>If any problem qualifies as the problem of consciousness, it is this one.</I><BR/><BR/>My reply is the standard one that's been around for decades in various forms.<BR/><BR/>Imagine an android like <I>Data</I> in <I>Star Trek: The Next Generation</I>. <I>Data</I> sees, hears smells, talks etc. He accumulates information as experience and has the computational power to learn form it.<BR/><BR/>Is <I>Data</I> conscious? If the answer is yes then clearly we have established that consciousness can be entirely explained in a materialist fashion.<BR/><BR/>If the answer is no, then it is up to the Courtiers to explain how <I>Data</I> differs from real people.<BR/><BR/>I don't see it. Until someone can explain what the problem is I'm not interested in delving into the "sophisticatd" solutions.Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-50988374058047710992009-01-15T23:45:00.000-05:002009-01-15T23:45:00.000-05:00Why does this remind me of The Courtier's Reply?No...<I>Why does this remind me of The Courtier's Reply?</I><BR/><BR/>Now, now!

Of course, I could go back and read the article again, but I find that reading Egnor's writings once is quite enough, and in general I prefer to have his thoughts pre-digested by someone sensible.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37148773.post-83549096383199338352009-01-15T02:57:00.000-05:002009-01-15T02:57:00.000-05:00Why won't Egnor allow comments over there so we ca...Why won't Egnor allow comments over there so we can tell him where he is mistaken? It's such a blatant non-sequitur to say that because the experience of redness can't be conveyed to someone who hasn't seen it, that therefore the experience of redness is "immaterial." Well, worse than a non-sequitur, it's a non-starter as "immaterial" is poorly defined. But leaving that aside, if Egnor really believes that the experience of redness is "immaterial," then perhaps he could demonstrate to us how to induce such an "immaterial" experience WITHOUT interacting with anything material (for instance, without looking at a MATERIAL object that is red).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37148773.post-80733147584734944632009-01-14T23:53:00.000-05:002009-01-14T23:53:00.000-05:00I have no reason to believe that Egnor is anything...I have no reason to believe that Egnor is anything but a competent surgeon.<BR/>But, otherwise, he's a woo master.

Presumably, she might already have read descriptions of colour (poetry and the like) and know that colour can affect human emotions. In principle, she might even have some idea how she would respond, what her favorite colour would be -- that should be predictable given sufficiently detailed data on her own neurology. I'm not convinced that "What it's like to experience colour" counts as "knowledge".

Actually this an experiment in reverse, structured with an assumption that needs to be proved. If contingent variables, can be thrown out at will, and whatever is convenient can be assumed as given, not needing proof or evidence, the experiment is useless. When Nagarjuna (the Buddhist) challenged Sankara (the Samkhya'ist) to debate, Sankara suggested that they frame the terms and tools of the debate. Nagarjuna suggested that they use logic, while Sankara disagreed, "Let us use evidence and first define perception. Because using logic, you can prove a dead man is alive!" Nagarjuna noded his head, and agreed to begin the debate the next morning. When the next day dawned, Nagarjuna and his followers were all gone!trutihttps://www.blogger.com/profile/06313354254836558451noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-21545131740961826792009-01-14T17:23:00.000-05:002009-01-14T17:23:00.000-05:00I don't know how the sudden appearance of new ...I don't know how the sudden appearance of new phenomenon would trigger new knowledge - perception yes. The only thing she would "know" is that she's perceiving something new, but she would ground this knowledge on her previous empirical work (and extrapolate that her new awareness likely means that there is new work to do and grant money to find). <BR/><BR/>However, not knowing anything of the new perception other than it’s been perceived has she gained anything in the way of knowledge not known before? And, does Mary herself have to know that she knows new knowledge or would having it without knowing it be sufficient. Does this thought experiment require an outside observer to know that she knows if she doesn’t realize she knows the new knowledge?<BR/><BR/>The physical characteristics that Mary knows to be associated with each entity that “we” call color, could possibly be called gloznort and bxzzdup, respectively, in Mary's world.<BR/><BR/>Upon becoming aware of the new sensation (a physical reaction) she’d have to form an hypothesis regarding the new input and then do some testing before she might come to the conclusion that the new phenomenon that she was experiencing related to her previously acquired data (thereby maybe concluding blue = gloznort & red = bxzzdup)? She could then build this new data into the general set. Now that would be new knowledge that she would know and be able to independently have verified. Science!<BR/><BR/>But then what if we and Mary are not real and we only exist as a thought and I’m just thinking there’s a you and a hypothetical Mary? Jeez, then there wouldn’t be a you.
