Let's say we see the moon and each of us sees it in almost exactly the same way in practical terms. Now the moon itself is what I would call a material body. But that materiality is not the same as what we see or what we know in objective terms. The actual lunar materiality as it exists in space represents a continuum amalgm of undifferentiated material properties which I would call aggregated sensation. And that amalgm reacts to other material amalgms in continuum terms according to the differences between and/or among them, things like sunlight, gravitation, etc. In looking at the moon what we see however is not its materiality as a whole but certain objective properties selected by our optical, perceptual, and cognitive faculties for a variety of evolutionary and volitional reasons. I say objective in this context but only because those properties have properties to begin with and not because the properties we see are material or because they are external or anything like that. These kinds of considerations we can only know after the fact. But the actual perception lies wholly within the brain/mind complex. And the same is true for everything we know of or can know of. This doesn't mean that material aggregates like the moon as it exists in outer space lie in the brain/mind complex. But it does mean that every property known of the moon and everything else lies in the brain/mind complex because that is where perception and cognition occur in terms of differences and differences are the reason perception and cognition occur inside the brain/mind complex and not anywhere outside. The typical solipsist views material aggregates as lying within the brain/mind complex and when he uses the terms objective or subjective what he is referring to are whether those things subject to his will or not. And most opponents of solipsism contend that subjective things lie inside the brain/mind complex and objective things lie outside. However this is an entirely fallacious distinction and badly misjudges the whole meanings of the terms subjective and objective. The only reason I wrote the previously cited thread on solipsism to begin with was that I was immensely frustrated by the conventional approaches to the problem. It's an old and very stupid philosophical doctrine that should have been dealt with centuries ago in definitive terms. The term objective simply refers to things having definable, known, or knowable properties. In point of fact there are no definable "things" in the brain/mind complex except properties and properties of other properties and those properties are the result of differences between material circumstances whether originating inside or outside the brain/mind complex. This is why the doctrine of differential cognition is crucial to the comprehension of what goes on in the brain/mind complex and why there is a mind in literal mechanical terms and why the brain is not just an especially complex piece of neural machinery. But it turns out that solipsism is also a critical limiting link in analyzing the problem. Not so much because it represents a credible possibility but because it highlights the issues involved, issues the importance of which I didn't begin to appreciate until I started considering the problem in critical terms. I realize that I have drawn several very fine and idiosyncratic terminological distinctions in the course of elaborating differential cognition. The terminology however isn't so important as the properties and mechanics of the brain/mind complex they describe. (By the way, Omega, this is the reason I didn't seem very enthusiastic about your suggestion regarding receptors, etc. These things may exist but the real issue is whether they are part of perception or cognition or just what.) So where do we get notions like inside or outside the brain/mind complex in definitive terms? It's all in the logical relations between and among the things we see in perception and in the mind. These are all objective so the fact that we see them has no bearing on the issue of inside or outside We judge whether something is inside or outside the brain/mind complex according to the relations between things. If what we see as the moon is occluded by other things, we know or infer that the moon lies beyond those things and those other things are intervening. And if those things lie beyond our arms or noses we know that those things also lie outside whatever is defined as lying within arms, noses, the skin, etc. This is exactly what babies do in the course of their cognitive development and why it takes so long. They have to formulate and automate all their cognitive relations in spatial, temporal, and logical terms. In other words they have to learn to judge things in terms of perspective. This is why we all tend to see things like the moon in very similar ways - because we all see it through exactly the same processes of logical inference applied to perspective. And this is also why Renaissance painters became famous for their renderings of spatial perspective, because it had unstated and previously unrecognized cognitive implications applicable to every individual. These relations are all objective. I'm going out on a limb here because I haven't analyzed or defined all the implications but I'm going to suggest that all true materialities are subjective and unknowable in this manner apart from objective differential aspects. (I use the term materiality here to describe aggregate sensory properties of things as a whole since the term material has objective connotations relating to properties of material things like steel balls, the moon, or whatever.) And to answer a previous question, yes dreams have properties as dreams that make them objective despite the fact thay they are figments and not material things. The same would apply to ideas, concepts, in fact anything that has definable properties one of which is not materiality. Which is why simply correlating an idea like objectivity with outside the brain/mind complex represents a treacherous and ultimately fallacious assumption. If we look at the ongoing discussions in this group we can easily see that it focuses primarily on issues between behaviorism and cogntive science. And early on I suggested that the issue might be so fractious because there were certain things cognitive scientists felt they had not resolved quite to their own satisfaction and that advocates of behaviorism were preying on that lack of resolution. Now I think the problem becomes a little clearer What I think is happening is that cognitive scientists are being caught in an intellectual bind between materialism on the one hand and solipsism on the other. Obviously this is specualtive on my part and is not intended to demean cognitive science or cognitive scientists. But cognitive science seems to be squeezed between materialism and solipsism to explain exactly how the brain/mind complex works such that it is neither just a neural machine and yet is not a subjective fantasy. I think most cognitive scientists ignore the issue and try to focus on results despite the lack of any definitive understanding. But I think this may represent the ultimate source of the sense of frustration and irritation I discern in such discussions. And I believe that the only way to resolve this issue is to come up with some definitive comprehension of how the brain/mind complex works in mechanical terms that is neither materialist nor solipsist in implication, an unexcluded middle in effect between materialism on the one hand and solipsism on the other. And I regard differential cognition as the only plausible alternative in self consistent mechanical terms. (Because the foregoing explanation has important philosophical and cognitive implications I'm going to cross post it to sci.cognitive and sci.philosophy.meta. But you are welcome to delete those if you wish in your own replies.) Regards - Lester
