ANNOUNCEMENT – GRAND OPENING!!! No, there’s not a new Wal-Mart coming to my home town . . . . . thank goodness. But there is a new section on my web site devoted to the science and mystery of human consciousness. Here’s the link:
WHENCE CONSCIOUSNESS
Many people today are fascinated by the question of just how our lives and our feelings and our perceptions and our theories and our dreams and such take place in a 8 by 6 inch shell full of wet, gray, squishy stuff. Just what is it about that squishy stuff (a.k.a. “the brain”) that makes it so special?
The more that neuroscientists look at the brain, the more they say that there’s nothing terribly special about it at all. It is highly complex and extremely organized, having many times the data storage and computing capacity of the largest supercomputer now in existence. We still can’t build a machine that nearly does what the brain does in terms of input / output signal processing (it takes in a whole lot of signals from all over the body, and puts out a whole lot of commands telling the various muscles and glands and organs what to do and how to do it all in near-perfect coordination). But the brain runs according to ordinary physical and chemical laws, and programming routines that aren’t all that different from our computer software (especially the newer generation of object-oriented programming). And it’s similar to what a whole lot of other living critters have behind their eyes.
But for whatever reason, the human brain seems to have crossed some kind of a threshold. It seems to inspire behavior reflecting belief in the possession of a transcendent soul and in an ontological purpose beyond food and safety and mating (the big three for most animals). We look at animals and see a blank stare most of the time. Then we look at ourselves and see a festival of ever-changing emotions; every micro-second of consciousness (including our dreams) invokes a felt response to our current state of sensory inputs and “inner processing”, e.g. imagination, impressions, ideas, brainstorms, delusions, hallucinations, etc. Animals also have emotions that are triggered and monitored by their gray matter; so why does our gray matter seem to take our emotions so personally? Just why does a machine following the normal rules of physics (that’s all that the brain scientists see when they study the brain; there ain’t no magic, no unheard-of forces and effects from some unknown dimension of reality) have such a vivid inner life?
I find it very fascinating; there’s a whole lot more to be said about consciousness. I really wonder, however, if there are ultimate answers. Perhaps this subject lies at the threshold of knowledge. Or maybe it is just a grand delusion, as some philosophers and psychologists and neuroscientists are arguing. Maybe there really is no surprise that a machine creates what we experience in our minds. Maybe when you break it down bit by bit, tackle the small problems and then put it all back together, it will seem entirely possible that science has all the answers. Maybe the grand question of consciousness (the “hard question”, as the experts call it) will just fade away, just as the sacred and extra-worldly nature of thunder and lightening faded away once we learned about electricity and sound waves and weather. Some people have had that “revelation” about consciousness, but the consensus doesn’t seem to have reached that point yet.
My pages on consciousness will be a work in progress. Hopefully they will improve as I learn more. If you are a true expert on the subject, you can probably pick out faulty thinking and dubious assumptions amidst my words. But at least you will appreciate that I’m trying to keep it mostly in the realm of plain language. Yes, I realize that plain language has its limitations; NASA could never have built an interplanetary rocket ship with plain language instructions. They clearly needed specialized mathematical, scientific and engineering symbols and syntax. The academic philosophers seem to think that a special language is also needed to truly plumb the depths of consciousness. Maybe they are correct; I’m still in the early stages of trying to learn their language. Nonetheless, I’d like to offer some technical quotes about consciousness from a smart fellow named Uriah Kriegel. Dr. Kriegel is a well accomplished scholar who is very involved in the consciousness field. He is kind enough to offer much of his work for free on the Internet (Dr. Kriegel’s Web Site). But unless you know philosophical techno-speak, be ready for some tough sledding. Try this, from his summary regarding consciousness:
“A mental state is phenomenally conscious iff it has phenomenal character . . . . phenomenal character is just the compresence of qualitative and subjective character . . . .
My theory of phenomenal consciousness revolves around the idea that conscious experiences have qualitative character in virtue of representing environmental features and have subjective character in virtue of representing themselves . . . . A mental state of mine is conscious only if it is for me, not only in me. (That is what gives it a subjective character.) This requires that I be aware of the state (in the right way). Awareness of something requires representation of it. Therefore, my state is conscious only if I represent it (in the right way).”
Hmm, I’m not sure yet just what that “right way” is. But seriously, Dr. Kriegel’s words are valuable and insightful; it’s just that you need to have all the background knowledge regarding philosophical abstractions and terms of art to appreciate what he’s talking about. For example, the terms “representing” and “representation” are loaded here. To lay people like me, representation isn’t such a big deal; a politician represents me in Congress, so what? But to the good Doctor and his like, “representation” is a big deal, with a very specific and important meaning.
If you’re up for it, then check out Dr. Kreigel’s consciousness stuff. But if you’re still floundering around with it all, then have a look at my pages and let’s compare our floundering notes. I’m not saying that stupid wild-ass guesses are better than well-structured thoughts; but stupid guesses are a starting point (for me, anyway), and I hope to progress from there. So if you’d like to visit my starting point, here’s the link again:

(And hey, if Uriah Kreigel or any of his ‘homies’ [his word] ever read this, then no hard feelings; if you would like to enlighten me and help me make my stupid guesses slightly less stupid, the e-mail “shout out” button is up top.)
