Could it be that maths, like space and time are part of our human cognitive apparatus in some way? — Tom Storm
MHO, cosmology (physics) concerns only modelling the development of what we call "the observable universe" and not "beginnings" or "origins" or "essences" of all things (metaphysics). — 180 Proof
With ucarr's indulgence and as a retired teacher of Computing Science, I would assume that ucarr is referring to quantum computings use of the very real physical phenomena of superposition. — universeness
In quantum computing a qbit can have more states than the two of the traditional binary bit.
"Just like classical bits, a quantum bit must have two distinct states: one representing “0” and one representing “1”. Unlike a classical bit, a quantum bit can also exist in superposition states, be subjected to incompatible measurements, and even be entangled with other quantum bits."
These states are quite 'real.' For me, its a bit like fully accepting the three physical states of solid, liquid and gas, and then being a little disturbed when you find out about 'plasma.' — universeness
Is this what you were referring to ucarr? with:
Quantum computing has something contrary to say about the last part of your claim.
— ucarr — universeness
Or maybe there are two and 57 at the same time, objectively. There can also be 4 and 57 at the same time. Are there also two pairs? where is the rule for counting? Surely it is not in the thing itself! Isn't it the case that when I said "two" I have given something that wasn't there… — JuanZu
a difference, a partition, a slice, a rule, a number simply different from 57 regardless of whether they are melons, apples or anything else? — JuanZu
So number is different from numbered things. — JuanZu
If you feel that crude metaphor conveys anything about the point at issue, perhaps it is because you don't understand it — Wayfarer
Practicing mathematicians pay virtually no attention to this philosophical discussion.
— jgill
And thus you are a dearly valuable exception to the rank and file establishment.
— ucarr
What does this mean, exactly? That paying no attention to a philosophical discussion is a virtue? And 'the rank and file' of what organisation, exactly? — Wayfarer
Well, if he doesn't know how to count he probably doesn't know that there are two things. He knows that there is a difference and that they are separated in space, that one thing is not the other, that they are similar, etc — JuanZu
I wouldn't say it "responds", it's not a mechanism. It's intentional content… — Hallucinogen
If numbers are physically_materially real, then how long and heavy are they? What shape and colour are numbers? — Corvus
What do you mean by differentiable here? — Lionino
You failed to show how that follows but since it is too early into the argument to be making contentions, I will just grant you. — Lionino
Everything from "There’s no reductio ad absurdum re:" to "Since any and all material objects, individually, present as a countable one, oneness, a countable number, acts as an essential attribute of each and every material object." sounds like Christopher Langan, meaning complete gibberish. — Lionino
…lots of mathematics deals with infinities. The natural numbers are an infinite set, and the set of real numbers are infinitely bigger than the set of natural numbers, and it gets worse as you go into the complex field. Calculus relies on the concept of infinity. You can have an infinite amount of infinities in mathematics that just keep growing. This does not seem to relate to the physical world. There is something about mathematics that is not about just the physical world. — Lionino
I should maybe be excluded from this discussion..
I don't believe in pure mental concepts at all, not the way you guys are talking about it
— mentos987 — mentos987
With this I seek to claim that our concept of math did not build the bridge. It was a fallen tree over a creek a long time ago that did — mentos987
To you it seems that apples and oranges are numbers, to me their numeration may simply be external properties that are only acquired in relationship. — JuanZu
"How can mental “objects” have causal effects upon the physics of the natural world? The answer is numbers." -- To me it seems incorrect, since our numbers are just us mimicking what is already there. — mentos987
All of it? A priori reasoning doesn't come from sensory stimuli, by definition. — Hallucinogen
Practicing mathematicians pay virtually no attention to this philosophical discussion. — jgill
Tosh. Kant detested materialism, as do I. — Wayfarer
Pure math has connection to the natural world only as indecipherable signification representing thermodynamic equilibrium.
Since mathematicians only use pure math for investigation of the ground rules concerning applied math, pure math is merely higher-order applied math.
— ucarr
Mysteries never cease :roll: — jgill
The distinction between pure and applied math is somewhat vague, one reason being that pure math may become applied math at times. A researcher in applied math could be working on a math scheme to solve a particular problem, like calculating the stresses on a modern fighter plane during sharp turns. Or, he could be pursuing a topic purely for its own sake, curious about what comes next - and then finds someone has used his results in an applied manner.
This happened to me. My interests are always in "pure" math (complex analysis) and I published a paper in 1991, I think, with no thoughts of it ever being "useful", only to find my principle result was employed in a multiple author sociology paper about decision making in a group. Of course, the author who cited and used my result paid no attention to the details. — jgill
Not uncoupled from the material world' does not mean 'material in nature' — Wayfarer
:up:A particle moves through space; some formulae do a good job of describing that movement and even predicting how it might go. But the particle and its movement are clearly prior. Mathematics, then, would seem to be derive from the world, the world in every sense prior. — tim wood
It has to be, since mathematical concepts are more general than physical entities, which only exist at a given coordinate in space. Mathematical truths whoever enjoy far greater comprehensivity. — Hallucinogen
I don't presuppose the existence of "physical minds" — Hallucinogen
What a priori axioms does physics possess? — Hallucinogen
Any that math possesses supports my position. — Hallucinogen
don't follow your line of questioning, ucarr. What's your point? — 180 Proof
We do not know. — JuanZu
If I have 5 oranges in one basket and I have 5 apples in another basket… — JuanZu
My 'anti-platonist pragmatics' (finitism?) comes to this: pure mathematics is mostly invented (re: pattern-making) and applied mathematics is mostly discovered (re: pattern-matching) — 180 Proof
…every physical fact depends on facts about this mathematical structure, but not vice versa. — Hallucinogen
If apples and oranges have intrinsic physical properties then the number(if it is different from numbered things to avoid breaking with the principle of identity)does not participate in those physical intrisic properties either. Therefore, the number is not something physical and is extrinsic to intrinsic physical things which are numbered — JuanZu
It is also necessary to define what you mean by a physical thing. — JuanZu
f I have 5 oranges in one basket and I have 5 apples in another basket, the 5 does not seem to participate in Appleness nor the orangeness. So the number is not the same as numbered things. — JuanZu
If it were the same (or if the number is an intrinsic property of numbered things), we would have to say that 5 apples are 5 oranges and vice-versa (or that 5 apples have the property of been 5 oranges and vice-versa) breaking the identity principle. — “JuanZu
…requiresan arbitrary starting point re: sequential processes. It can be considereda “working” starting point, but there’s no logical — 180 Proof
…we ought not mistake the maps we make for the territory itself? — 180 Proof
"Must be"? Why must there be? If you look closely enough, you will find the imperative securely rooted in your need for one, in the (your, and mine too) logic of the thing. But logic is descriptive and only seems to be prescriptive. That, or show, extra-logic, how and why it must be. — tim wood
Why include me in your reply to Gnomon? — 180 Proof
...the abstraction, or concept, of "consciousness" ...a self-reflexive activity — 180 Proof
...because by definition consciousness is excluded from this paradigm. — Unknown
Physicalism only excludes non-physical concepts from modeling (i.e. explaining) how observable states-of-affairs transform into one another. In this way "the paradigm" is epistemologically modest, or deflationary, limiting its inquiries to only that which can be publicly observed – accounted for – in order to minimize as much as possible the distorting biases (e.g. wishful / magical thinking, superstitions, prejudices, authority, etc) of folk psychology/semantics. — 180 Proof
We physicalists do not "exclude consciousness" (i.e. first-person experience) but rather conceive of it as a metacognitive function – e.g. phenomenal self-modeling – of organisms continuously interacting with and adapting to each other and their common environment. — 180 Proof
Actually, I didn't comment on the visibility of Mass & C. But, for the record, all of the equation's elements are imaginary & invisible abstractions. And none of them is tangible Matter, although Mass is a numerical measurement (mentalization) of Matter, a concept, not an object. So, I don't know how you decided that the invisibility of of numerical concepts contradicts my description of Einstein's equation, in which I referred to Matter, not Mass, as "tangible". Does any of that "matter" to you? :joke: — Gnomon
I call EnFormAction a "shapeshifter", because like physical energy, it can transform into a variety of manifestations. The most famous example is Einstein's E=MC^2 equation of invisible Energy and tangible Matter and a non-dimensional number. They are different expressions of the same essential substance. — Gnomon
Mass is a numerical measurement (mentalization) of Matter, a concept, not an object. — Gnomon
I call EnFormAction a "shapeshifter", because like physical energy, it can transform into a variety of manifestations...They are different expressions of the same essential substance. — Gnomon
...I'm always looking up words, the definitions of which often lead me to other words I have to look up, — Patterner
...we might say, snowflakes, in general, have a design, and each one has its own unique design. — Patterner
...is that the kind of thing you’re talking about? — Patterner
We grew within the universe, which has consistent principles, and are made of the universe's materials, which are subject to those principles. Is there a reason to think an intelligence that developed in such a way would not be able to recognize these principles? — Patterner
What is the relationship between numbers and order? To what degree can you have one without three other? To what degree are they not the same thing? — Patterner
No. I did not, and do not, declare the order is designed. — Patterner
Again, I did not, and do not, acknowledge design. — Patterner
No, I did not, and do not, describe cosmic mind. — Patterner
Yes. The order pre-existed the life that arose within it. — Patterner
What I mean is, will thinking that objects 'possess an inherent attribute that can be labeled "number"' lead to a dead end? Will thinking it is not an attribute of objects, but of the universe's order, that we are recognizing lead to a dead end? After all, we might approach things differently, depending on which we take as our starting point. — Patterner
Do you believe a brain confined to a vat will eventually start counting? — ucarr
Certainly not. I don't believe a human could come to any intelligence or consciousness under those circumstances. I believe sensory input is essential. — Patterner
The universe is consistent. Laws of physics, mathematics, and whatever else, are the same everywhere...If they were not, we would have chaos, and I doubt life would have arisen at all. — Patterner
We evolved, and exist, in this universe, with its consistent principles. Meaning they are within us. I think counting is our recognition of these attributes, these consistent principles, of the universe. It makes sense that we recognize the principles of our own existence when we see them outside of ourselves. — Patterner
Do you believe a brain confined to a vat will eventually start counting? — ucarr
Certainly not. I don't believe a human could come to any intelligence or consciousness under those circumstances. I believe sensory input is essential. — Patterner
