By Harry Binswanger
Mathematics is the headquarters of Platonism-the reification of abstractions and the primacy of concepts over percepts. Even Euclid defined “line” as “breadthless length,” something not of this world, and the moderns define “one” in terms of nonbeing (the null set). In this lecture, drawing on a few incisive statements by Ayn Rand, Dr. Binswanger gives perceptually based definitions of key mathematical concepts, such as quantity, measurement, one, number, point, line, infinite, and mathematics itself.

The thickness of the image on your screen is nill. That is to say, it is negligible (in most contexts). The thickness of your imaginary image of a line is also nill (otherwise it wouldn't be an image of a line).

9:10 Counterexample to Dr. Binswanger: Euclid also states a plane is length and breadth but no thickness, which might be equally alarming to Dr. Binswanger, but the shadow he is measuring is a mathematical plane, the shadow has no thickness. The shadow of a line has no breadth. Abstraction of a point has having no length as well is fine. Its a very small thing, smaller than any ruler can measure but exists at a place and time, like a point charge.

If you want to teach geometry, you don't want to start with something with length and breadth and thickness as you haven't explained those yet. The square you eventually want to talk about needs a corner to start your drawing at, and that corner has no length or breadth or thickness. Sure the depression and ink or graphite does, but we don't want to discuss engineering friction of carbon on paper to talk about a square. Everyone can see a dot is that which has no length, or else we'd call it a line. Line-of-sight meaning straight ahead without breadth

In reality, we will (at some points) disagree about what counts as the past, the present, the future, and the distance between objects, and all that we will agree on is that causality is real. Given causality as the fundamental basis of all the rest, we will eventually need to give way to the fact that the aether exists and that time is a dimension alongside the 3 spatial dimensions, and that everything except causality is relative.

Allow me to correct the definitions of "point", "line", and "plane"/"surface". Point: a location in space and/or time, omitting the various measurements of length, breadth, and depth of the representation marker. Or A point is that which occupies a space but has its parts omitted. Line: a line is length with the differences in length and the other dimensions in general are omitted. Surface: a surface is that with length and breadth with the differences in length, breadth and depth in general are omitted.

Unfortunately the argument leads to this: For anything to exist it must have non-nill thickness in infinitely many dimensions. If the volume is a cube, it has six surfaces, but a surface having nill thickness means it is itself a volume, which would have surfaces, but every surface is a volume, which has surfaces... etc. This means there cannot be a "cent". Another issue. If you draw a triangle on a piece of paper the line drawing of the triangle has a thickness we agree, but the negative space of the drawing has created a second triangle inside the graphite lines. That triangle has a surface without thickness and exists itself as a plane without thickness. That triangle is not the paper.

I would say irrational numbers represent real quantities, it’s just that they can’t be written as ratios. The definition of The sqrt(2) is the quantity of length of a right triangle when both sides are of length 1. PI is not 3.1415…… because infinity doesn’t actually exist. PI is just PI, a particular quantity that may only be written as a number as PI. It is that number that is the limit of the perimeter of a unit-lengthed n-gon (n*sin(180/n)) as n goes to “infinity”, i.e. it approaches this quantity as n keeps increasing, and we call it PI. (as n increases, there is a pattern of it going closer and closer, but never beyond, this quantity we call PI). Real numbers describe quantity due to the continuous nature of the world.

Leonard Peikoff's "History of Philosophy: Aristotle: Epistemology" lecture, especially at the 10 minute mark, explains what Binswanger has done wrong in this lecture. Binswanger is being Platonic, or anti-Platonic. As Jean Mulroney's anti-value theory works, Harry has held the Platonic world as true, but rejects it outright and therefore just refuses to use abstractions, but this is exactly Plato's problem. Peikoff lecture, knocks down this lecture by showing that the thinking is the same: "That because the world is actually always 3 dimensional, that lines and surfaces cannot exist and therefore world of forms. Plato and Binswanger both accept this premise, but Plato embraces abstractions as real and king, and Binswanger rejects the abstractions and embraces over defining concepts such that they always represent one of the members of the kind.

When he says "numbers don't really exist, they're conceptual tools", I would say: numbers don't really exist, they are *fictional characters,* which are *sometimes* used as conceptual tools. And, indeed, much of math was invented specifically *for* the sake of using it as a tool. But that doesn't mean that it's in any way "wrong" to talk about those mathematical objects which _only exist in the fictional story,_ like infinities, dimensionless points, and the empty set. There's nothing wrong with continuing the story for story's sake, and maybe eventually discovering that the newly invented characters have a practical use. Just like it happened with complex numbers.

Numbers are valid methods used by the mind in identifying reality. They are not products of imagination, eg, the characters in a novel. The mind has definite properties which thus act in a definite way. Reality is what it is and man can know it from many perspectives, eg, concrete, abstract. Man can know concrete trees as concrete trees or know them as forest. In both cases he knows concrete trees. But a different kind of knowing. Eg, a near-sighted person uses eyeglasses or not. Reality remains. Blurriness is a perspective. Reality is not blurry.

@alexhauser5043 Plato's arguments are, by modern standards, uncareful and only surface logical. Kant was explicitly anti-reason (see the famous quote from the preface to the 2nd edition of the Critique of Pure Reason). Kant is brain-crackingly hard to read but Hegel is truly unreadable. Russell did not intend to be anti-reason, and he's all over the place in his views (except for the right view). I agree he's superficial. Mach, I have (like you) some respect for. His relativism bears thinking about. Carnap is silly. Kripke, from the little I've read, is on the right track. Lewis, I was actually a co-student with him (and his former wife Stefanie) in Hilary Putnam's class on meta-ethics at MIT. I don't recall his views. Quine, terrible, but also didn't think he was anti-reason. His "critique" of the Analytic/Synthetic Dichotomy ("Two Dogmas of Empiricism") is coo-coo. His criticism of the a/s is weak (viz., no one has given a clear definition of it), and that's the essay where he famously says that physical objects are comparable, epistemologically, to the gods of Homer.

The three quotes Harry uses at the start are both entirely and abusively taken out of context, as well as actually supporting his thesis. Russell, despite his issues, is agreeing with Binswanger, there are no real lines without breadth, at least for the common man on earth, and therefore math is a subject where we use lines and points and it works but since lines and points don't really exist then how can we know what we did was true? This is what Binswanger is saying the whole time (whether he knows that or not). The Kline quote was abised heavily! Kline is literally attacking the Platonists, and how they Platonists believe in contradictions because they need the world of forms. Kline is saying exactly what Binswanger is saying. Einstein is also stating the same thing. He also is agreeing with Binswanger. He is saying, lines don't actually exist, we cannot experience them, and yet they work for abstracting and producing machines that operate perfectly well given a subject matter which is so abstract that its contents don't actually exist. This out-of-context strawmanning is the worst part. I don't even know what to say about that dishonest approach, except to say that he clearly knew followers won't check his sources...

Ayn Rand: "With the grasp of the (implicit) concept “unit,” man reaches the conceptual level of cognition which consists of two interrelated fields: the conceptual and the mathematical. The process of concept-formation is, in large part, a mathematical process." "Let us now examine the process of forming the simplest concept, the concept of a single attribute (chronologically, this is not the first concept that a child would grasp; but it is the simplest one epistemologically)-for instance, the concept “length.” If a child considers a match, a pencil and a stick, he observes that length is the attribute they have in common, but their specific lengths differ. The difference is one of measurement. In order to form the concept “length,” the child’s mind retains the attribute and omits its particular measurements. Or, more precisely, if the process were identified in words, it would consist of the following: “Length must exist in some quantity, but may exist in any quantity. I shall identify as ‘length’ that attribute of any existent possessing it which can be quantitatively related to a unit of length, without specifying the quantity.” The child does not think in such words (he has, as yet, no knowledge of words), but that is the nature of the process which his mind performs wordlessly. And that is the principle which his mind follows, when, having grasped the concept “length” by observing the three objects, he uses it to identify the attribute of length in a piece of string, a ribbon, a belt, a corridor or a street. The same principle directs the process of forming concepts of entities-for instance, the concept “table.” The child’s mind isolates two or more tables from other objects, by focusing on their distinctive characteristic: their shape. He observes that their shapes vary, but have one characteristic in common: a flat, level surface and support(s). He forms the concept “table” by retaining that characteristic and omitting all particular measurements, not only the measurements of the shape, but of all the other characteristics of tables (many of which he is not aware of at the time)." "Observe the multiple role of measurements in the process of concept-formation, in both of its two essential parts: differentiation and integration. Concepts cannot be formed at random. All concepts are formed by first differentiating two or more existents from other existents. All conceptual differentiations are made in terms of commensurable characteristics (i.e., characteristics possessing a common unit of measurement). No concept could be formed, for instance, by attempting to distinguish long objects from green objects. Incommensurable characteristics cannot be integrated into one unit. Tables, for instance, are first differentiated from chairs, beds and other objects by means of the characteristic of shape, which is an attribute possessed by all the objects involved. Then, their particular kind of shape is set as the distinguishing characteristic of tables-i.e., a certain category of geometrical measurements of shape is specified. Then, within that category, the particular measurements of individual table-shapes are omitted. Please note the fact that a given shape represents a certain category or set of geometrical measurements. Shape is an attribute; differences of shape-whether cubes, spheres, cones or any complex combinations-are a matter of differing measurements; any shape can be reduced to or expressed by a set of figures in terms of linear measurement. When, in the process of concept-formation, man observes that shape is a commensurable characteristic of certain objects, he does not have to measure all the shapes involved nor even to know how to measure them; he merely has to observe the element of similarity. Similarity is grasped perceptually; in observing it, man is not and does not have to be aware of the fact that it involves a matter of measurement. It is the task of philosophy and of science to identify that fact."

Does that mean that the number 100 is an "invalid concept"? No.. Can you imagine "everything"? Obviously not. Does that mean that the concept of infinity doesn't exist? No.. We're talking about the concept of existence and non-existence itself. Saying it's an invalid concept is like saying that the predicate logic is invalid because its quantifiers ∃ and ∀ are invalid concepts.

Maybe next time consult with a mathematician and a philosopher of mathematics so you don't go and make a total ass of yourself. But then, this is about as mathematically sophisticated as Ayn herself, which is to say sophomoric.

@@TeaParty1776 Evidence of what? What are you asking here? What would you accept as evidence that Dr. Binswanger should have consulted a professional mathematician? The only evidence one can really present is the knowledge of mathematics and why this video was, sadly, an embarrassment.

I've long found Rand's near total lack of knowledge of mathematics and the physical sciences bizarre. How can someone glorify reason and rationality endlessly while having no working knowledge of its most perfect products?

@@alexhauser5043 Rand is a philosopher, not scientist. Philosophy is the base of all knowledge because its based on common human experience, not specialized knowledge. Claims that contradict common human experience are false. Science begins in mans sense experience of the concrete , material universe, not in conjectures and refutations. Scientists, like all people, are man facing the universe, not brains in a vat pumping out statistics based on arbitrary, subjective ideas. Thats the mentality of primitive savages prior to the discovery of scientific method by the first scientist, the philosopher, Aristotle. A human being cannot live his life moment by moment; a human consciousness preserves a certain continuity and demands a certain degree of integration, whether a man seeks it or not. A human being needs a frame of reference, a comprehensive view of existence, no matter how rudimentary, -Ayn Rand

@@TeaParty1776 "Rand is a philosopher, not scientist." Rand was a polemicist above all else. Her writing lacks the argumentative rigor and analytic character of genuine philosophy. I expect ALL intelligent persons to have some interest in mathematics. Indifference to the subject is the virtual sine qua non of the pseudo-intellectual. Please refrain from lecturing me with Randist copypasta in your subsequent replies; I read Rand extensively when I was a teenager. Nothing I wrote implies that philosophy is superfluous or inferior to science.

Mathematics derives from the Creator's purpose which is to limit the Eternal Chaos. This purpose is formulated from The Mystery of the Light. And He insured that Man would discover mathematics by constructing Man from the very essence of God Himself, once removed through transmutation. So, through the imperative of the divine purpose from which he was created, Man discovers mathematics in order to describe the Creation around him. And there can be only one commodity which can limit the Chaos.
