tjohnson Posted September 12, 2007 Share Posted September 12, 2007 What does that got to do with it? Your so-called space is merely a logical extension of the concretes. Without the concretes, it would not be imagined at all.MichaelYou seem to be saying that mathematical objects have their origins in our own perceptions and, if so, I don't have a problem with that, but in advanced mathematics there is little or no resemblance to anything we perceive. This is perhaps the most fascinating thing about mathematics, that is appears so disconnected from perceptions and yet can uncover relations that can be seen empirically.

And maybe that the reason advanced math can uncover empirical relations is because of this origin. I am certainly not saying that the methodology of math is the same thing as a perceptual concrete.The only reason for a need to say it at all is that people who wish to bash Rand (and Peikoff) from the academic side overly emphasize the advanced math as some kind of proof against them and pretend that Objectivists demand that all math correspond to a physical thing "out there" that it is measuring, sort of like a numerical concept for perceptual concretes. In some ranting and railing against this, I have even read passionate discourses about how math is completely cut off from our perceptions, without even a basic origin. This is usually called "a priori knowledge" or "analytical" or "abstract" (with a somewhat different meaning than Objectivists give it) or something like that during these rants.I keep saying this, but there is plenty of legitimate stuff to criticize in Rand (and Peikoff). There is no need to pretend that they are against advanced math and abstract theorizing. But that is the impression that is constantly sold. (I do admit that Peikoff's cosmology, comments on quantum physics and several other pronouncements are strange and do lend themselves to bashing. Idem for several melodramatic statements by Rand.)Michael Link to comment Share on other sites More sharing options...

It's a rather radical idea but one can imagine an example by thinking about how our eyes integrate static pictures into a continuously changing image similar to what is done in integral calculus. This may explain why mathematics does have such success in discovering relations because, after all, our consciousness is a joint phenomenon of what is around us and how we interact with it.

Michael Stuart Kelly Posted September 12, 2007 Share Posted September 12, 2007 How is an uncountably infinite, linearly ordered, locally compact set similar to our nervous system?Bob,From common sense:Uncountably infinite. The infinite does not exist in the sense of establishing a limit on it. For human use, it only exists as a possibility on which to locate limited things. With sight, to use one example, there is no limit to how many new things it is capable of seeing (from the thing end and restricted to things that fall within the size, etc., that can be seen). So long as the conditions for seeing are met, the range of objects and backgrounds that can be seen are uncountably infinite. Linearly ordered. In a more general way, there are the nerves. We are basically processing tubes and tubes are linear. You progress from the beginning, go through the middle and get to the end. That's the linear way tubes work. Locally compact. There are pretty clear laws of nature operating on the nervous system that do not apply to other things. There are not many and they are local to nervous systems.Big-picture-wise, there are similarities.Michael Link to comment Share on other sites More sharing options...

These are the governing principles of everything "out there." In this respect, math certainly does.Big Picture wise how are Klein Bottles (a kind of four dimensional manifold with no inside or outside) similar to our nervous systems.Hell. That's easy. From common sense:No start or end. With sight, to use one example, there is no start or end point as to what new things are capable of being seen (from the thing end and restricted to things that fall within the size, etc., that can be seen). And we can keep seeing the same things over and over. I could go on, but you get the picture. Besides, as cool as Klein Bottles are, they are not the total of existence, so in any analogy, it would be a double standard for them to be used for the total of the nervous system.For as much as we may not like it, we are part of the big picture. We are not above it or outside it. That hurts, but there it is.Michael Link to comment Share on other sites More sharing options...

When did he form this theory?Ellen___Not sure I understand, doesn't a motion picture do the opposite, ie. take a bunch of static pictures of a continuously changing image? What I am talking about is what happens when we watch a motion picture. His major work, Science & Sanity, was published in 1933.Incidently, dividing up a continuously changing process into static "snapshots", like the camera, is what we do in differential calculus. Our brains cannot process change directly, we need to break it into static steps and words are just that - static abstractions from changing processes (mental images, feelings, etc.).

Guyau Posted November 28, 2009 Share Posted November 28, 2009 Here is a page that tells of the wonderful works of Ruth Millikan:http://www.philosophy.uconn.edu/department...likan/index.htmHere is a little piece I wrote concerning Millikan's biological approach to truth theory (up to 1993):http://www.bomis.com/objectivity/millikan.htmlMillikan’s Contribution to Materialist Philosophy of MindNicholas Shea (2006)This paper is a nice introduction to Millikan’s account of intentionality as from evolutionary biological nature.

This time, ithas some different complex relational property which is its content, one that we specify bymentioning cats, amongst other things. However, there is another crucial differencebetween the two cases: in one Pierre is thinking something true, in the other somethingfalse. And the truth or falsity of Pierre’s belief seems to be fixed by its content, togetherwith some facts about the world (in particular, facts about the nature of canine and felinevocalisations). Belief contents must be some complex relational property that is suited toforming the basis of this distinction between truth and falsity. Arguably, not any olddescriptive distinction will do here, since it is a difference that can have normative import.There is a sense in which a representation that is misrepresenting is doing somethingwrong. What kind of complex relational property can be like that?In Korzybski's language, if a representation correctly represents then we have similarity of structure, if not, the structures are dissimilar and can mislead us the same way that following an incorrect map can.

Christopher Posted November 28, 2009 Share Posted November 28, 2009 GS,In Objectivism, all symbolic systems like words, logic and math have their basis in reality. Math is abstract, but it does follow the law of identity. As reality does also, it works. That's the initial connection. It is not just a set of arbitrary rules in the mind completely disconnected from the rest of reality.I connected one set of dots and came up with the following. We are part of reality, therefore we fall under the same laws of organization that govern reality, therefore, our mental system of organization (even when using symbols) works according to the laws of organization that govern reality. So in a metaphysical sense (law of identity), all math is applied math. A math unit is a "thing." It is just a mental thing and not a perceptual thing.MichaelJoseph Campbell would disagree. I believe he would argue that man uses symbols from external reality to describe internal states and processes that are actually independent of the reality we perceive.

It doesn't matter why physics and mathematics are similar in structure to the world in which we live, it just is. Thomas, Jeffrey’s questions are reasonable and of lively interest to some thinkers. Those questions have been pondered by physicists Hertz, Einstein, Feynman, and most famously, by Wigner. Philosophers of science and mathematics today continue to work on competent answers.I wouldn’t be too quick to say for questions: things just are the way they are in the respect the question seeks explanation. I remember when I was first learning a little about gauge theory and supersymmetry in the 70’s, it really struck me that to that point I really had never wondered, and would have supposed it unreasonable to expect any explanation of, why the most elementary massive particles have the masses they have. I would have said: they just do.Some questions are not sensible, of course, such as: Why is there something rather than nothing? “Something is” is where sensible regress ends.

He is basically discussing how there are pan-cultural pan-historical themes in human literature and mythology that use different symbols but demonstrate the same basic psychological architecture. He specifically talks about symbols and how there are no problems with religious symbolism so long as the symbols are taken to represent inner psychological states rather than objective concretes.

So he added these two together and came up with the conclusion that Judeo-Christian culture was automatically anti-woman & anti-life -- not because of any patriarchal heritage, but because the symbol of the Ouruborous was supposedly hated by the ancient Hebrews.
