OK, you're moving into a different area of philosophy (or perhaps I took you away from it. I can't remember) But then this argument you make here would also make it more likely to not talk about substance. We would notice differences, not substances.What you wrote about substances and physics and definable elements are not definitions; they are separate descriptors of what we consider reality. We can't verify reality; we can verify differentness of instances of what we consider reality. — god must be atheist
We can verify differences. We can verify that when we do X and Y we get Z.That's why I wanted to avoid the whole issue. Reality can be decided over (i.e. what we consider reality) but it can't be verified. — god must be atheist
I agree in a couple of different ways with you.Some users stopped talking to me, because I said matter is a matter of belief. — god must be atheist
[1] We live in an ordered universe that can be understood by humans.
[2] The universe consists entirely of physical substances - matter and energy.
[3] These substances behave in accordance with scientific principles, laws.
[4] Scientific laws are mathematical in nature.
[9] Space and time are separate and absolute. — god must be atheist
The OP questions our Ontological definition of Nature & Being : Physical (P) vs Non-physical (non-P) existence. That Either/Or distinction has boiled down to defining "substance" and "entity". So, I'll ask a few quibbling questions for clarification. This is not criticism, just a few pertinent open questions to think about.
[1] asserts an ordered universe, and [3] seems to attribute that logical organization to "principles & laws". Which category would you place those orderly forces into : P or non-P? If physical "Laws" (or regulations) are detectable only by rational minds, not by empirical methods, what is their Substance : Matter or Math or Mind or Aristotelian Essence, or Other?
Into which category would you place "Mathematics" [4] : P or non-P? If Math is a physical substance, is it Matter or Energy or Mind or Other? If neither Matter nor Energy, how can Math exist according to [2]? Supernatural existence has already been ruled-out by the topical question. So, if Math is non-P, in what sense is it Natural? — Gnomon
I wonder if maths, time and space and all those tricky matters are just part of a generalized neurocognitive system that allows us to understand the world and they have no reality outside of experience. — Tom Storm
In a way, the problem is that existence and something being true is synonymous. From that we get confused. — ssu
I agree with you, but I lost you at this part. — god must be atheist
We seem to be using terms "Math", "Mind", and "Physical" in different senses. Equating the Chalice with the Wine. So, let's get more definitive.My own take is maths is an abstraction, a product of human minds. Minds appear to be physical things in as much as we have no evidence of a mind without a physical body. — Tom Storm
So, let's rephrase the question : are quality, structure, space, and change P or non-P? What is your take on the physicality of those features of Nature? Note : I'm not referring to the container, but to its contents -- not to a machine, but to its functions. — Gnomon
I wonder if maths, time and space and all those tricky matters are just part of a generalized neurocognitive system that allows us to understand the world and they have no reality outside of experience. — Tom Storm
Can we demonstrate that there is even such a thing as non-natural/super natural? What would the properties of non-natural be, I wonder? — Tom Storm
Again, the word "Mind"*2 is typically intended to distinguish the complex lump of tissue that controls the neural systems of the body from its functions or faculties : thought, imagination, memory, will, and sensation. Now, what is your take on the physicality of those natural phenomena? — Gnomon
Can you empirically study Ideas, Feelings, & Concepts by dissecting the physical body/brain? — Gnomon
This is merely a typical philosophical failure to adequately define our terms & categories. We talk past each other, not because as laymen we are out of our depth, but because one of us is discussing empirical "Physics and Neuroscience" and the other is discussing theoretical Philosophy. Fortunately, it's not all Greek to me, or to you, I assume.I think we're just repeating ourselves and playing with language. And as far as physics and neuroscience goes, we are both out of our depth. — Tom Storm
[2] The universe consists entirely of physical substances - matter and energy. — god must be atheist
[6] The behaviors of substances are caused. — god must be atheist
[9] Space and time are separate and absolute. — god must be atheist
How did you arrive at that novel conclusion? I have entertained (inferred from E=MC^2) the above-my-paygrade-notion that Matter is essentially slowed-down (decelerated) Light energy. For example, at lightspeed a photon is massless, but as it slows down to matterspeed, it transforms into mathematical Mass, which we measure in terms of physical Matter. I have found a few statements by scientists that could be interpreted as pointing in that direction, but nothing definitive.Energy converting into matter is decceleration - conversion of potential to change into something changeable (rate - and thus the beginning of time and space - the only medium in which rate (change) can occur. — Benj96

Can pure energy interact with itself? — Gnomon
A photon is said to be "massless"*1 when it is moving at lightspeed (its definitive state). In that case, it is essentially Pure Energy, undiluted by Matter (pace 180wooboo)*2. But when a photon slows down to a fraction of lightspeed, some of that Potential Energy is converted into Mass, which is a mathematical expression of its potential to be measured in terms of Matter. The "rest mass"*3 of a photon is only a hypothetical concept*4, since in practice a resting ("matterspeed") photon is no longer a photon (potential), but a particle of some material (actual).Well the photon is "matterless" yes (not physical/solid/has no dimension) but not massless. . . .
If a photon was massless how could it impart its mass to matter when it decelerates? — Benj96
Any use of the terms "Metaphysics" & "Beliefs" will terminate a dialog with several posters on TPF. That reaction is probably due to previous encounters with philosophically-frustrating dogmatic religious positions based on ancient Theology. However, personally, I find the notion of Meta-physics (non-physical) meaningful as a complementary perspective to Physics. Aristotle divided his encyclopedia on Nature (phusis) into two different categories of human understanding : 1> as known by the senses (physics) and 2> as known via reasoning (metaphysics). But, lingering prejudice against centuries of dominant Catholic dogma is strong on this forum . . . and with good reason. However, that rejection sometimes throws-out a beautiful baby with the nasty bathwater, and tars Philosophy with the brush of Religion, and identifies cutting-edge Science with New Age mumbo-jumbo. Ironically, over the last century, modern (post-quantum) physics has been rubbing our noses in the malodorous margins where Atomism (Materialism) dissolves into Fieldism (Mathematicalism).I could not call these points [1] through [10] metaphysics, rather, points of belief.

There's not much else for us to discuss then.

Yes. But that ancient dichotomy won't fly in the modern world. "Physical" is merely what we know about Nature via the mammalian senses. And, "Super-natural"*1 implies some form of extra-sensory perception (ESP), and an invisible realm above or behind mundane Reality*2. Which implies that ESP can perceive things & actions that are beyond the reach of mundane Science --- which ultimately depends on artificial (technological) extensions of the 5 physical senses.The answer to the OP would depend on how one defines "physical" and "supernatural". Is one the negation of the other? — Agent Smith
Is "Narnia" the negation of Earth? Are "dancing angels" the negation of pinheads? Or hallucinations the negations of facts?The answer to the OP would depend on how one defines "physical" and "supernatural". Is one the negation of the other? — Agent Smith
So, in Western philosophy, does metaphysics concern (the) "super-natural"? No – not 'nature beyond nature' (infinite regress, etc) but instead something like 'the common denominator of every constituent of nature as a whole' or 'what within nature makes nature whole' (re: ).Physical is synonymous with natural (and nonphysical with formal (e.g. mathematics, logic, etc.))
Supernatural" a term used to indicate woo-of-the-gaps – "beyond" – in what we (think we) know about nature, however, amounts to babytalk? mystogogy? non-explanations? ... synonymous with superstitious.
Much like travelling speed of a car is dependent on the car's system, but the speed itself is separate from the system, and is in effect a measurable non-physically existent quality. — god must be atheist
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
