What's not true? You said: "(sets) can be assigned any possible order (in the sense of humanly created order), with absolutely no regard for truth or falsity." I asked what it means for the possibility (of the order) to have "absolutely no regard for truth or falsity". — Luke
Has that been the basis of your argument from the start? Funny, since I've seen you argue against the eternalist block universe in other threads. You really are a troll. — Luke
Possibility has "no regard for truth or falsity"? What does that mean? — Luke
You can't have impossibility without possibility. — Luke
I've spent the last couple of posts saying that math is a lie, math is fiction, math is untruth in the service of higher truth, and you put words in my mouth. It's not fun and there's no point. — fishfry
You do need to understand the concept of the necessary approximateness of all physical measurement. I can't imagine why you would take a stance so fundamentally wrong. — fishfry
You strongly imply that the inherent order is able to be apprehended in these quotes. We must be able to apprehend the inherent order if it is "describable" and we are able to see it. — Luke
That's right, and then you forced upon the conversation your idiosyncratic idea of "the inherent order" that is unrelated to sets or ordering in mathematics. Fishfry and Tones tried telling you this, but you weren't interested. — Luke
Thanks? I guess. But this does not answer the question of how your concept of "the inherent order" relates to "order" more generally. You could start with your own ideas of "order" and "the inherent order" and explain how these relate to each other. Why is "the inherent order" not a type of "order"? — Luke
Have you considered that what you say might appear to be contradictory because it is contradictory, and that the problem is with your metaphysical edifice rather than with my understanding? — Luke
The Pythagorean theorem in the real world is literally false. It's close but no cigar. It's approximately true, that's the best you can say. But the point here is that you are on record claiming the Pythagorean theorem is "very true." So you are not in a position to deny saying that. — fishfry
Idealized mathematics (as opposed to say, numerical methods or engineering math, etc.) is perfectly exact. That's its supreme virtue. — fishfry
Now it seems to me that the starting point for an interesting discussion is to note that the Pythagorean theorem is literally false in the world, and perfectly exactly true in idealized math; and from there, to meditate on the nature of mathematical abstraction. How we can literally tell a lie about the world, that the theorem is true, and yet that lie is so valuable and comes to represent or model an idealized form or representation of the world. — fishfry
But if you deny both these premises, one, that the P theorem is false in the world (close though it may be) and perfectly true in idealized math, then there is no conversation to be had. And for what it's worth, your opinions on these two statements are dramatically at odds with the overwhelming majority of informed opinion. — fishfry
The fact that Moby Dick changed the name of the ship from the Essex to the Pequod, changed the names of the characters, and invented episodes and stories that never really happened, does not detract from the novel in the least. A representation or abstraction stands alone. — fishfry
It obtains it every day of the week. It obtained idealized exactness in the time of Euclid. — fishfry
There are no dimensionless points, lines made up of points, and planes made up of lines in the world. — fishfry
The mathematical theory of infinity is a classic example of an abstraction that has nothing at all to do with the real world. And yet, without the mathematical theory of infinity we can't get calculus off the ground, and then there's no physics, no biology, no probability theory, no economics. So THAT is the start of an interesting philosophical conversation. How does such a massive fiction as transfinite set theory turn out to be so darn useful in the physical sciences? Where's Eugene Wigner now that we need him? — fishfry
Is this a reference to what you've been trying to talk to me about from time to time? Universals, and how they bear on mathematical abstraction? What does it mean, exactly? After all I frequently point out to you that mathematical ontology posits the existence of certain abstract entities, and this is exactly what you deny. If I understood this point about universals better (or at all, actually) I'd better understand where you're coming from. — fishfry
This was before you let anyone know that the inherent order was noumenal and invisible, which is right around the time I believe you changed your position. You started from this position: — Luke
That is, you started out telling us that the actual/inherent order can be perceived with the senses and apprehended, then you changed your position to say that the inherent order cannot be perceived with the senses or apprehended, and now you're saying that the inherent order is invisible but it can (again) be perceived with the senses. At least, that's your latest position. — Luke
If inherent order is not a type of order, then I don't understand what you have been arguing about regarding mathematical order. Why did you previously allow for other types of order, such as best-to-worst? — Luke
You previously spoke of "perceive" and "apprehend" as opposing concepts, but now you consider them synonymous? For a long stretch of the discussion, you repeated in various forms that we perceive with the senses, as distinct from apprehending with the mind: — Luke
Meta, I'm going to withdraw from this phase of our ongoing conversation. Perhaps we'll pick it up at some time in the future. If you can't agree that real world measurement is necessarily imprecise and that mathematical abstraction deals in idealized exactness, we are not using words the same way and there is no conversation to be had. I don't think you would be able to cite another thinker anywhere ever who would claim that physical measurement is exact. That's just factually wrong. — fishfry
Right. Sorry for assuming that we're talking about humans. Once we meet aliens or once we evolve to the point where we classify as a different species then yes, we may see more. — khaled
It is justified by definition. You have access to the reason in your mind. You don't have access to "the reason that orders the world". — khaled
Any theory about "the reason that orders the world" is just that, a theory. As long as it accounts for own reasoning and perceptions the only thing separating it from any other theory is Occam's razor. — khaled
If you do believe in evolution then you ought to believe that it is more likely than not that our reasoning and perceptions are incomplete. Not only is this supported by experimental evidence (Hoffman) but also we can easily find scenarios where there are things we cannot detect that affect us, such as UV light. — khaled
That you don't understand that all physical measurement is approximate, and that math deals in idealized exactness that does not correlate or hold true in the real world, is an issue I would have no patience to argue with you. You are simply wrong. Physical measurements are limited by the imprecision of our instruments. This is not up for debate. But I do see a relation between your misunderstanding of this point, and your general failure to comprehend mathematical equality. — fishfry
Inherent order is only one type of order (you also allow for other types such as best-to-worst). How is it that we do not perceive order with the senses in general, but that we do perceive inherent order with the senses specifically? — Luke
It was not until recently that you began arguing that we do perceive inherent order with the senses and can "see" or otherwise "sense" invisible physical entities such as molecules, ultraviolet light, and the inherent order. — Luke
You will note I maintain the distinction here between order and inherent order. You must have been aware of this distinction in your own response when you contradicted your latest argument and affirmed that: "1) We do not perceive order with the senses". It is therefore a complete fabrication to attribute your own contradiction to my misunderstanding or lack of awareness of the distinction between order and inherent order. — Luke
In other words, you explicitly state here that we do not sense the inherent order specifically. — Luke
Of course sense perception is involved! Where have you been? We've been talking about seeing things and inferring an order. My point was that we do not sense the order which inheres within the thing, we produce an order in the mind. I never said anything ridiculous like we do not use the senses to see the thing, when we produce a representation of order for the thing. — Metaphysician Undercover
In this particular case, there is no direction towards the answer. Rather, every direction is as good as any other. — khaled
And this is true of everyone. It's not about the limitations of the individual but the limitations of being human. — khaled
Only a fool would want to know something they know they can’t know. — khaled
You have stated both that we do and do not perceive (i.e. see) order with the senses. This is not a failing on my part. — Luke
It's not complicated; you contradicted yourself. I think you see that now, which is why you have given up. — Luke
As such, I don't care about "the reason that orders the world". Maybe it is the same as the reason in my mind, or maybe the reason in my mind is just an "evolutionary shortcut", a hack, a parody of the real thing optimized for survival. Either way, I don't have access to "the reason that orders the world" so I don't care about it. — khaled
That is the point that I was trying to make. I think it calls into question Kenosha Kid’s view that there is ‘one objective reality’ which all interpretations try to approximate or interpret. I agree that reality may be one, but that unity must necessarily transcend subject-object dualism, meaning that it’s out of scope for naturalism as such. — Wayfarer
Say, did you know that the Pythagorean theorem is false in the real world? — fishfry
Do you think that we can see infrared and ultraviolet light just because it exists in the world? — Luke
I have not misunderstood. — Luke
No middle 'e' in judgment. I can't take anyone seriously who can't spell. — fishfry
The point is that the process of abstraction necessarily, by its very nature, must omit many important aspects of the thing it's intended to model. You prefer not to engage with this point. — fishfry
That's fantastic. The Pythagorean theorem is a beautiful, gorgeous, striking, brilliant, dazzling, elegant, sumptuous, and opulent example of an abstraction that is not based on ANYTHING in the real world and that has NO INDUCTIVE CORRELATE WHATSOEVER. I am thrilled that you brought up such an example that so thoroughly refutes your own point.
The Pythagorean theorem posits and contemplates a purely abstract, hypothetical, mathematical right triangle such that the sum of the squares on the legs is equal to the square on the hypotenuse. No such right triangle has ever, nor will ever, exist in the real world. — fishfry
Your own example falsifies this. I can never confirm the Pythagorean theorem in by observation of the world. I can only prove it deductively and never inductively. — fishfry
This is the complete opposite of induction. — fishfry
But getting back to the larger point: A map is a formalization of certain aspects of reality that necessarily falsifies many other things. Just as a set is a formalization of the idea of a collection, that necessarily leaves out many other things. I have a bag of groceries. I formalize it as a set. The set doesn't have order, the grocery bag does. The set doesn't have milk, eggs, bowling balls, and rutabagas, the grocery bag does. — fishfry
I think what you are saying is that an abstraction faithfully represents some aspects of the thing, and leaves out others. — fishfry
The essence of your argument is that "inherent order" is so tightly bound to the thing, that it can not be separated by an abstraction. I believe that's the core of our difference. Do I have that right? — fishfry
For purposes of the conversation, yes, I'll stipulate that. So what? It's how mathematical abstraction works. Just like the Pythagorean theorem does the same thing. — fishfry
Well now you're just arguing about my semantics. If I don't use the word generalization (which by the way I have not -- please note); nor have I used the phrase inductive conclusion. I have not used those phrases, you are putting words in my mouth. I said mathematical models are formalized abstractions, or formal abstractions. Or formal representations. That's what they are. The need not and generally don't conform to the particulars of the thing they are intended to represent. Just as an idealized right triangle satisfies the Pythagorean theorem, and no actual triangle ever has or ever will. Oh what a great example, I wish I had thought of it. Thank you! — fishfry
You say that like it's a bad thing! Ok, imaginary fiction then. But a useful one! — fishfry
So if you have a problem, it's your problem and not mine, and not math's. — fishfry
Well a set isn't actually a collection. A set is an undefined term whose meaning is derived from the way it behaves under a given axiom system. And there is more than one axiom system. So set is a very fuzzy term. Of course sets are inspired by collections, but sets are not collections. Only in high school math are sets collections. In actual math, sets are no longer collections, and it's not clear what sets are. Many mathematicians have expressed the idea that sets are not a coherent idea. It would be great to have a more sophisticated discussion of this point. I'm not even disagreeing with you about this. Sets are very murky. — fishfry
So therefore perhaps I should stop wasting my time trying to argue that math is inspired by reality, or that math is an abstraction of reality, and simply concede your point that it's utter fiction, and put the onus on you to deal with that. I could in fact argue the abstraction and inspired-by route, but you bog me down in semantics when I do that and it's tedious. — fishfry
If I see 100 bowling balls fall down, "bowling balls always fall down" is an inductive conclusion. But F = ma and the law of Newtonian gravity are mathematical models from which you can derive the fact that bowling balls fall down. It's a physical law, meaning that if you assume it, you can explain (within the limits of observational technology) the thing you observe. — fishfry
But this is not an important point in the overall discussion. — fishfry
Ok. I don't think the definition of induction versus a formal model is super important here. But "bowling balls always fall down" is simply a generalization of an inductive observation, whereas the law of gravity lets you derive the fact that bowling balls fall down; and that in fact on the Moon, they'd weigh less. The latter is not evident from "bowling balls always fall down," but it is evident from the equation for gravitational force. — fishfry
This point is not central to the main point, which is that models must necessarily omit key aspects of the thing being modeled. — fishfry
Ok fine, then order is physical and the mathematical theory of order is an abstraction or model that necessarily misses many important real-world aspects of order yet still allows us to get some insight. That's the point of abstraction, which I already beat to death in my last post. — fishfry
I'm explaining to you that whatever your concept of physical order is, mathematical order is an abstraction of it, which is necessarily a lie by virtue of being an abstraction or model, yet has value just as a map is not the territory yet lets us figure out how to get from here to there. — fishfry
I've conceded your point, now that I understand what you mean by inherent order. — fishfry
It's an abstraction that necessarily includes SOME aspects of the thing being modeled and excluces OTHER aspects. Just as a street map includes the orientation of the roads but ignores the traffic lights. — fishfry
That's right. A map is correct about some aspects of the world and incorrect about others. It's an abstraction. — fishfry
Maps are imaginary principles and don't formalize anything? Do you see why I think you're trolling? — fishfry
If you would engage with my examples of maps and globes, I would find that helpful. — fishfry
And sets represent aspects of collections, which exist in the world. And they omit "inherent order," which for sake of argument I'll agree collections in the world have. — fishfry
Well that has nothing to do with anything. Maps don't show things that aren't there. The question is, how do you feel when a map omits things that ARE there, like wet lakes and rivers, cars, and the size and scale of the actual territory being modeled. — fishfry
Then you don't see it. — Luke
And you claimed earlier that we could not possibly see it, in principle — Luke
Have you rejected your claim that we can see the inherent order? — Luke
2. How do you reconcile this with your statements that order is not visible? — Luke
You said that we sense a foreign language without apprehending it. — Luke
Now you say that we neither sense nor perceive the meaning of a foreign language: — Luke
Do you have an attention deficit or memory disorder? You seem incapable of maintaining your own position. A moment ago you were talking about "the reality of the situation" that we see the inherent order without apprehending it, and now you've switched back to saying that we can neither see nor apprehend the inherent order. If you think there are two different senses of the word "see" involved here, then define them both. Because one of them seems to refer to what we cannot see, which is not a familiar definition of the word "see". — Luke
Can you not hear foreign languages? This is a terrible analogy. This is something which we can perceive but cannot apprehend. Your analogy with molecules is equally bad, since it is something we can apprehend but cannot perceive. It is (or very recently was) your position that we can neither perceive nor apprehend the inherent order. Remember? You said that order is "not visible". — Luke
There's no contradiction here, I take it? — Luke
So how can it be seen? — Luke
From your side it must seem like you're being tag-teamed by Luke and myself, but I'm not reading his posts. I'm not aware of that half of the conversation. — fishfry
It's an abstraction intended to formalize an aspect of nature. If you think it's a generalization of something, you might be missing the point. Hard to say. — fishfry
I think you are missing the point. If I drop a hundred bowling balls and I say, "Bowling balls fall down. That's a law of nature," then THAT is an inductive conclusion.
But if you see 100 bowling balls fall down and you go, F = ma, that is an abstraction and a mathematical formalization. You don't seem to have a firm grasp on this. Do you follow my point here? — fishfry
Your notion of induction is wrong. "All bowling balls fall down," is an inductive conclusion. F = ma is a formalization. — fishfry
But there are non-physical parts of the world that we are interested in, such as quantity, order, shape, symmetry, and so forth. Those are the non-physical parts of the world that are formalized by math. — fishfry
Things in the world have order, and we have a mathematical theory of order that seeks to formalize the idea. — fishfry
On the other hand, of course there are non-physical, non-part-of-the-world abstractions too. Chess, for instance. Chess is a formal game, it's its own little world, it has a self-consistent set of rules that correspond to nothing at all in the real world. Knights don't "really" move that way. Right? Say you agree. How can anyone possibly disagree? — fishfry
But you are the one that insists that physical collections of things have an inherent order. And that's what the mathematical concept of order is intended to formalize. Things in the world have order, and we have a mathematical theory of order that seeks to formalize the idea.
Right? When mathematicians formalize numbers, they're abstracting and formalizing familiar counting and ordering. When they create abstract sets, they are formalizing the commonplace idea of collections. A bag of groceries becomes, in the formalization, a set of groceries. Surely you can see that. Why would you claim math is not based on everyday, common-sense notions of the world? — fishfry
Like what? Can you name some of these? Sets correspond to collections. — fishfry
But again I ask you, exactly WHICH mathematical ideas are not based on or inspired by the natural world? You must have something in mind, but I am not sure what. — fishfry
That's a useful mindset to have, so that we don't allow our everyday intuitions interfere with our understanding of the formalism. But of course historically, math is inspired by the real world. Even though the formalisms can indeed get way out there. — fishfry
The truth is in the thing. — fishfry
If I want to study the planets I put little circles on paper and draw arrows representing their motion. The truth is in the planets, not the circles and arrows. I hope you can see this and I don't know why you act like you can't. — fishfry
First, sets are intended to model our everyday notion of a collection. And in order to do a nice formalization, we like to separate ideas. So we have orderless sets, then we add in order, then we add in other stuff. If I want to put up a building, you can't complain that a brick doesn't include a staircase. First we use the bricks to build the house, then we put in the staircase. It's a process of layering. — fishfry
Our formalization begins with pure sets. It's just how this particular formalization works. — fishfry
If I represent a planet as a circle, you don't complain that my circle doesn't have rocks and and atmosphere and little green men. I'll add those in later. — fishfry
You act like all this is new to you. Why? — fishfry
I refer you to Galileo's sketch of Jupiter's moons. With this picture he started a scientific and philosophical revolution. Yet anyone can see that these little circles are not planets! There are no rocks, no craters, no gaseous Jovian atmosphere. Why do you pretend to be mystified by this obvious point? — fishfry
Do you feel the same way about maps? — fishfry
Tell me this, Meta. When you see a map, do you raise all these issues? — fishfry
An order that is shown can be seen: — Luke
But we cannot see the inherent order: — Luke
The idea, as with anything else mathematical, is that we have some aspect of the real world, in this case "order"; and we create a mathematical formalism that can be used to study it. And like many mathematical formalisms, it often seems funny or strange compared to our everyday understanding of the aspect of the world we're trying to formally model. — fishfry
After all bowling balls fall down, and the moon orbits the earth. To help us understand why, Newton said things like F=maF=ma, and F=m1m2r2F=m1m2r2. And E=12mv2E=12mv2, and things like that. And you could just as easily say, "Well this doesn't seem to be about bowling balls. These are highly artificial definitions that Newton just made up." And you'd essentially be right, while at the same time totally missing the point of how we use formalized mathematical models in order to clarify our understanding of various aspects of the real world. — fishfry
So if you can see the difference between a real world thing like order, on the one hand; and how mathematicians formalize it, on the other; and if you are interested in the latter, if for no other reason than to be better able to throw rocks at it, I'm at your service. — fishfry
That's the mindset for understanding how math works. You seem to object to math because it's a formalized model and not the thing itself, but that's how formal models and formal systems like chess work. They are not supposed to be reality and it's no knock agains them that they are not reality. They're formal systems. If you can see your way to taking math on its own terms, you'd be in a better position to understand it. And like I say, for no other reason than to have better arguments when you want to throw rocks at it. — fishfry
I don't care about your latest position. In case you missed it, my entire point for the last three or four pages is that you changed your position three or four pages ago. This is obvious from the quote that you somehow managed to overlook: — Luke
Here you say that "the exact spatial positioning" is not what is being demonstrated (i.e. shown) in the diagram. — Luke
Which is it? — Luke
But you didn't say any of those things. Instead you just accepted the mathematical definition I repeatedly gave you, and then kept arguing from your own private definition. When I finally figured out what you were doing, I was literally shocked by your bad faith and disingenuousness. I'm willing to have you explain yourself, or put your deliberate confusion-inducing equivocation into context, but failing that I no longer believe you are arguing in good faith at all. You have no interest in communication, but rather prefer to waste people's time by deliberately inducing confusion. — fishfry
My God, you wield your ignorance like a cudgel. I could have just as easily notated the two ordered sets as:
* ({1,2,3,4,…},<)({1,2,3,4,…},<) and
* ({1,2,3,4,…},≺)({1,2,3,4,…},≺)
which shows that these two ordered sets consist of the exact same underlying set of elements but different linear orders. Remember that sets have no inherent order. So {1,2,3,4,...} has no inherent order. The order is given by << or ≺≺. — fishfry
By "shown" you do not mean "displayed". After all, "it is not visible". Therefore, you must not be making the argument - as you did earlier - that we see the order but do not apprehend it. — Luke
You are saying that the "exact spatial positioning" is logically demonstrated by
("shown" in) the diagram, but it is not apprehended? If the exact spatial positioning is not (or cannot be) apprehended, then how has it been logically demonstrated by the diagram? — Luke
Of course, location is intelligible, conceptual, so it's not actually sensed it's something determined by the mind, just like meaning. When you tell someone something, they do not sense the meaning. This is "showing" in the sense of a logical demonstration. And the point is that upon seeing, or hearing what is shown, the mind may or may not produce the required conceptualization, which would qualify for what we could call apprehending the principle. More specifically, the conceptualization produced in the mind being shown the demonstration is distinct and uniquely different from the conceptualization in the mind which is showing the demonstration, therefore they are not the same. That is why people misunderstand each other.. — Metaphysician Undercover
I answered the question, it's just like a logical demonstration. Like when one person shows another something, and the other makes a logical inference. All instances of being shown something intelligible, i.e. conceptual, bear this same principle. We perceive something with the senses and conclude something with the mind. The things that I sense with my senses are showing me something intelligible, so I produce what serves me as an adequate representation of that intelligible thing, with my mind. — Metaphysician Undercover
Inherent order is a wider concept, applying in particular to biological systems and natural phenomena. Ordering is more specific having to do with listing. I think you are discussing the latter. — jgill
Sorry, I haven't kept up. Are you speaking of inherent order or inherent ordering? — jgill
But you now concede that sense perception is involved in showing. — Luke
I would say that the word "shown" here means what is visible in, or displayed by, the diagram; not what is demonstrated or proved by the diagram. — Luke
All that remains for you to explain is your contradictory pair of claims that (i) the inherent order is the exact spatial positioning that we do apprehend in the diagram; and that (ii) we are unable to apprehend the inherent order. — Luke
You avoid the question instead of answering it. How can location be shown to someone without it being sensed? — Luke
"Shown" in the sense of a logical demonstration is different to "shown" in the sense of your statement: "the exact spatial positioning shown in the diagram". That's obvious. — Luke
Do you think that location can be shown to someone without it being sensed? — Luke
As a result you can find yourself living with people who are simple in thought who don't give the extra effort to think from a philosophers perspective. — Tiberiusmoon
Given that (1) we do not perceive order via the senses and that (2) we cannot apprehend inherent order, then how can the inherent order be the exact spatial positioning shown in the diagram? — Luke
Even if I grant you that there is an inherent order to the universe, how can you say that the inherent order of the diagram is the same as the order that we perceive via the senses, or "the exact spatial positioning shown"? — Luke
I note your change in position. You are no longer arguing that the inherent order cannot be apprehended. You have now adopted the weaker claim that the inherent order cannot be completely apprehended. — Luke
More importantly, as far as I can tell, inherent order is not the kind of order that mathematicians are concerned with. — Luke
You're factually wrong.
Is the set {0,1,2,3,4} identical to the set {0,1,2,3,4}? I have to assume you'd say yes.
But 2 + 3 and 5 are both representations of the set {0,1,2,3,4}. So they're identical. — fishfry
Well, math does not violate this principle. 2 + 3 and 5 are identical. They are both representations of the set represented by {0,1,2,3,4}, which of course is not actually "the" set, but is rather yet another representation of that abstract concept of 5. — fishfry
Only to the extent that you don't seem to think a thing is identical to itself. Because when mathematicians use equality, they mean identity, and this is provable from first principles. They either mean identity as sets; which is easy to show; or, they often mean identical structurally. This is a more subtle philosophical point. — fishfry
You said that "1) We do not perceive order with the senses" and that "2) We cannot apprehend the inherent order". Therefore, how do you know that what's shown in the diagram is the exact positioning of the parts (i.e. the inherent order)? — Luke
Isn't the positioning of the dots that I perceive the "perspective dependent order" which you earlier stated was not the inherent order? So how can the diagram show the inherent order to anybody?
The inherent order cannot be perceived by the senses and we can't apprehend it, anyway. — Luke
If "We cannot apprehend the inherent order", then how do you know that our representations are inaccurate? — Luke
If the inherent order is unintelligible to the human mind by definition, then what makes inherent order preferable to (or distinguishable from) randomness? — Luke
On the contrary. 2 + 3 and 5 are mathematically identical. There is not the slightest question, controversy, or doubt about that. — fishfry
You spoke of an "external perspective", which implies an internal perspective. You might recall I asked you about it and you responded: — Luke
Your current argument is that we do not perceive order with the senses, and that we cannot apprehend inherent order at all. Therefore, how is it possible that the inherent order is the exact spatial positioning shown in the diagram? — Luke
