It is classic, but I would like to know what you all think.

... based on the identification with a body.Rade said:I agree with Ayn Rand on this point..."a vast part of higher mathematics...is devoted to the task of discovering methods by which various shapes can be measured" (e.g., integral calculus used to measure area of circles as one example). In this way, the mental process of "concept formation" and "applied mathematics" have a similar goal--identfying relationships to perceptual data.
Inventions are never "wrong", some are just better then others.
matt grime said:Boy does that Ayn Rand (appear to) know jack about mathematics, unless she has such a suitable vague notion of what a 'shape' and its 'measure' are as to make her statement vacuous.
saltydog said:I'm flat-out disappointed in this. Perhaps you've already addressed the question asked by the thread author in an eariler post and just don't want to be bothered again by what many would consider a premier philosophical question in mathematics. And please spare me any retaliation against my post as I've never claimed to be an ace in mathematics. Just expected more from one I think is.

HallsofIvy said:You're disappointed that he responded (negatively) to your post rather than addressing the orginal post- which you also did not address? If you think you were addressing the orginal post then either you did not understand what it was asking or you did not understand what Ayn Rand was saying (I suspect the latter). The original post asked, as you said yourself, a "premier philosophical question in mathematics". The Ayn Rand quote did not address itself to that but simply spoke of mathematics as a search for formulae for "measuring shapes"- without specifying what she meant by either "measuring" or "shapes".

As defined by Rand, measurement "is the identification of a relationship--a quantitative relationship established by means of a standard that serves as a unit". "A shape is an attribute of an entity--differences of shapes, whether cubes, spheres, cones, etc. are a matter of differing measurments; any shape can be reduced to or expressed by a set of figures..."matt grime said:Boy does that Ayn Rand (appear to) know jack about mathematics, unless she has such a suitable vague notion of what a 'shape' and its 'measure' are as to make her statement vacuous.
saltydog said:Hall, I request you kindly explain your response above to me: Matt did not respond to my post; he responded to Rade's post. The original poster simply asked if math is invented or discovered. I believe I did address that question. Why do you think I did not?
Is Mathematics Discovered or invented?
Mathematics is a product of the human brain. What better way to co-exist in a world than to become in some ways like that world. I think the human brain has done that by evolving a neural architecture that closely resembles the non-linear dynamics all about the world we live in. It is this synergy in dynamics I feel, that allows the emergence of a phenomenon called mathematics that works so well in describing nature. Mind, nature, and math. They are all cast from the same mold. It is not that math exists indepenently within nature to be discovered, but rather that nature has conspired to re-create itself within us in such a way that leads to its dynamic representation within our brain that we call mathematics.
matt grime said:Moreover a complete ignorance of the philosophical issues is no barrier to doing maths showing just how unimportant *mathematically* this question is.
Further, I do not think it is the premier philosophical question in mathematics. It might be the premier mathematical question in philosophy, or the premier question in the philosophy of mathematics; I do not regard them as being part of mathematics.
You are correct, Rand is not a mathematician, she is a philosopher. Let me continue with Rand definitions if it will help since you now ask about "entities". Rand defines "entity" as something that exists that has a specific nature and is made of specific attributes. Then she offers some examples. She claims that of the human senses, only two provide direct awareness of entities, sight and touch. The others give only awareness of "attributes" of entities (e.g., hearing, taste, smell). Then, she states: "attributes cannot exist by themselves, they are merely the characteristics of entities, motions are motions of entities, relationships are relationships among entities". Hopefully this helps explain why Rand views mathematics as discovered from shapes of entities gained via perception, and not from relationships of entities invented by the mind. I have no idea the answer to this thread question, I only posit what I understand Rand to be saying, since she is no longer with us to tell us directly. If Rand has something to offer to this thread, great, if not, so be it.matt grime said:If we think shape is soley an attribute of euclidean geometry, the platonic solids, things you can draw on paper, then it is obviously false. And Rade's explanation of her definitions just introduces the now undefined entity of 'entity', but that is typical of non-mathematicians trying to do maths.
veij0 said:mathematical truths are analytic truths. Since they are actually true because of the definition of its particles. 1+1=2 because the definition of two ones and a plus is two. One apple plus one apple makes two apples. That is the definition of two. Basically the same pinciples flow through the whole concept of maths.
