It is fairly clear that one can create new neural pathways which yield altered "instinctual" or "subconscious" thought. Certainly behavior can be altered by training and, if one is to refer to the neural pathways generating that behavior as "thought", one cannot categorize these neural pathways as established in an absolute sense.
Sure we can! The epitome of established, fixed neural pathways seems to be the computer. Incapable of altering themselves, except to within the degrees established by the program. I think of computer programs much in the way of the subconscious. Capable of dealing with familiar problems and established patterns. So much so that it's far better at dealing with these problems than your conscious mind.
Essentially, I would classify thought as the ability to alter your established pathways. When your unconscious (squirrel) mind approaches a problem that it's unsure of to a certain degree, it gives it to the conscious mind. The conscious mind isn't very efficient like the subconscious, but it does unexpected things and is able to arrive at conclusions that the subconscious isn't able to. Once the conscious mind arrives at a conclusion, it's passed off as input into the subconscious, altering the established pathways.
Hence, without the ability to think, your subconscious would act quite consistantly and would me more akin to a machine.

My son-in-law did his graduate work in neural network simulations and they do a pretty good job of simulating instinctual thought but they are certainly not what I would call *established*. In most such designs they the circuits continue to be free to adjust their weights even after those weights have pretty well stabilized.
I haven't studied the particulars of neural networks, but from what I know, I assume that they will continue to emulate a certain stage of learning, and may be (once more perfected) capable of far better learning than the human mind.

Not really, it depends very much on what decisions you decide to leave to your unconscious mind and I think you have the power to do that. You can make what seems to you to be a logical decision recognizing that your perceptions might be wrong or you can forget everything and just go with your gut instincts. Idiot savants prove that even square roots can be done by the unconscious mind if it has been trained to do it.
Well, the point isn't so much that it's impossible, but that it's useless for you or me or your average Joe. Let's take a more complex problem:
You have an extensive collection of regular octogons called Norps. Each edge of each Norp has two points called Gips. The Gips are evenly distributed along the edge, such that the distance from each Gip to its neighboring vertex and to its neighboring Gip are equal. Further, each Gip is connected to exactly one other Gip by means of a straight line segment. Your extensive collection contains one of every possible such Norp. How many Norps do you have?
The unconscious is at a loss. Or, at least, *mine* sure is! Maybe you can instinctively guess at a solution without the aid of your conscious mind, but it's at a severe disadvantage, particularly if you've never come across such a problem ever before. If you've dealt a lot with combinatorial mathematics and geometry, maybe your subconscious can make a slightly educated guess, and wind up in the right ballpark, but let's say for the sake of argument, that you ask this of a 4th grader. Their subconscious may pull a number out of thin air, but they'd be fully aware that it was purely a guess, and totally unsure of how to relate the answer with the problem. The CONSCIOUS, however, can begin to deal with the problem, because it isn't based on routine, it's based on innovative ways of applying association and logic.

I am firmly convinced that the very choice to be conscious of a problem is a squirrel decision. I think it is very easy to get so in the habit of doing some very complex things that we are not even consciously aware of what we are doing. In most cases, if asked, we can easily explain what we were doing because we have done it so often but is some situations, it is possible to recognize that we are really consciously unaware.
That's totally true. For example, I'm told that champion chess players are much the same way. They can play the first dozen moves or so of a chess game VERY well without really needing to think. And when asked "why did you move your bishop there?", it takes them a minute, because suddenly they have to re-evaluate the problem consciously. In fact, as evidence has shown, the conscious re-evaluation might be totally mistaken, for just the reasons you stated above! They're forced to re-evaluate with only what the subconscious mind provides them as input. There may in fact be TONS of other contributing factors, but the conscious mind doesn't necessarily get them all, and may not re-evaluate in the same way that the subconscious evaluates normally!

I am firmly convinced that, once the subconscious has discovered a usable solution to a problem, it no longer bothers the conscious mind with the issue. I think that, so long as the unconscious mind is convinced it knows what is supposed to be done, it doesn't even bother the conscious mind.
Quite right, I think. My personal thought is that the higher the degree of uncertainty that exists in a problem, the more the conscious becomes involved. And when faced with a totally new problem, the subconscious pretty much throws up its hands and passes it off to the conscious.
Doctordick said:
My point was that what you call your perceptions are assumed solutions (or "squirrel" conclusions) provided to you conscious mind by your unconscious mind.
Well, that's true, but I'll hold that it isn't always so. Learning words is a great example. Upon hearing the word "soda" my subconscious translates the raw auditory input to my conscious, and my head is filled with the concept of a fizzy, sugary, liquid. I'm barely even aware of the pure auditory sounds, and filter out background noise, and maybe even the accent of the voice which says the word.
But it wasn't always true. At one time, my subconscious got a strange mixture of what it assumed to be speech, and passed that off to my conscious for evaluation. "Hey, conscious mind-- I heard this word 'soh-dah'. Dunno what it means. Little help?"
But even earlier in development, I hear a mishmash of raw auditory input, and my subconscious has no idea what to do with it at all. It doesn't even recognize that this thing as speech, or even as a distinct sound. It probably distinguishes it as "a sound that my mother is making", but doesn't even know how to distinguish the word from the surrounding speech. Again, the unconscious passes it off to the conscious, which is pretty helpless at that stage. Especially with a word like "soda".
And even before that, I may not be able to even distinguish it as a distinct sound. My mother's voice saying "soh-dah" is grouped together with the birds outside, the TV on in the other room, the echo of the room, the rustle of clothing, and anything else that might be going on.
I think that at each stage, the conscious helps develop the direction of the subconscious-- that's the only way the subconscious grows beyond that which is purely instinctive.
In such a way, you're right, the conscious mind rarely deals with the rawest form of inputs. But it can. But the point really is that you NEED perception in order to think. Effectively, you need somthing to think about! It doesn't really matter WHERE that perception comes from (IE your subconscious or the raw "outside" world), just so long as you're perceiving *something*.
Doctordick said:
Because, in order to distinguish things, your unconscious mind must have already associated different incoming data with these thing and in order to associate things you need to be able to distinguish them. How can you associate things which cannot be distinguished?
No no-- I agree that association presumes distinguishment. And I agree that distinction presumes perception. But I don't see how perception assumes both association and distinguishment, which is I believe what you were asserting way down there... In my list, I was attempting to go from the most basic requirements (IE that which does not presume anything) to the more advanced requirements (that presume much). But I believe each is a useful distinguishable component towards developing thought.

What I am saying is that the "reductionist" attack on the problem is the wrong attack.
Well, I think it's sort of right and wrong. I think Hegel was the first I read who started talking about several different aspects of thought evolving *together*, whereas beforehand the philosophical assumption was the concept of the "blank slate" or "compartementalized slate". However, I think that the reductionist explanation may be helpful to understanding. Feel free to disagree, however.

The goal of science, as it is done by humanity today, is to justify that mental model that their subconscious handed to their conscious mind before they were two. They totally ignore the question as to how such a mental model is achieved. Consciously or unconsciously acquired, an attitude of achieving results by ignoring relevant issues is called working in ignorance. The important issue here is the fact that the existing solution they think they are searching for is swept under the rug unexamined as the very first move of their analysis.
Actually, I find that a rather unfair critique. Your implication is rather existential in nature, which never seems to result in much. Effectively, reality may not be what we THINK of as reality, but we have no choice but to DEFINE reality as such, because without that assumption, we have nothing. Your desire to assess the development of the mental model of the universe is certainly valuable, but how do you do it? And how is it productive? And how is it verifiable?
Doctordick said:
The only problem I have with your attack is that it smacks of exactly the same kind of thinking which has already failed to succeed for many many years. It entirely ignores the very problem I just pointed out. Essentially your solution is organized from the perspective of a very complex scientific explanation; and that explanation was designed to justify a mental model of reality concluded by your subconscious mind at roughly the age of two.
I don't see how-- in fact, I think it addresses the problem pretty precisely. Its failure lies in the definition and enacting of meaningful distinction and association. Those areas need to be honed to quite a degree.
I'm not sure where you're seeing the "perspective of a very complex scientific explanation" in my explanation. Could you show me where?
