You have shown me no connection between my understanding that we know the world from a unique perspective, and the possibility of performing counting and/or measuring operations on all that we know. — Dfpolis
As I understand it, to say there is a universal law just is to say that there is a universally invariant form of action, a natural behavior which operates at all times and all places regardless of human awareness and opinion. — Janus
What principle allows you to say that there is a "natural law" which is the cause of this action, rather than something else, like gravity, which is causing the action? — Metaphysician Undercover
Real numbers [and the like] don’t begin to exist by virtue of there being someone around who learns how to count. The mind evolves to the point where it is able to count, that is all. The same goes for ideas and universals, generally. They are the constituents of the ability to reason but they’re not the products of reason. — Wayfarer
Einstein, A. (1933). On the Method of Theoretical Physics. Lecture delivered on 10 June 1933 at Oxford University.The axiomatic structure (A) of a theory is built psychologically on the experiences (E) of the world of perceptions. Inductive logic cannot lead from the (E) to the (A). The (E) need not be restricted to experimental data, nor to perceptions; rather, the (E) may include the data of Gendanken experiments. Pure reason (i.e., mathematics) connects (A) to theorems (S). But pure reason can grasp neither the world of perceptions nor the ultimate physical reality because there is no procedure that can be reduced to the rules of logic to connect the (A) to the (E). Physical reality can be grasped not by pure reason (as Kant has asserted), but by pure thought.
EINSTEIN: I cannot prove scientifically that Truth must be conceived as a Truth that is valid independent of humanity; but I believe it firmly. I believe, for instance, that the Pythagorean theorem in geometry states something that is approximately true, independent of the existence of man.
If gravity operates always and everywhere then it just is a natural law; that's what the term means. — Janus
I know some physicists, and they do not practise physics as if the descriptive laws of physics represent some "laws of nature"[. They work to understanding existing laws of physics and establish new ones, without concern for whether there is such a thing as laws of nature. Like I said, this is an ontological concern. — Metaphysician Undercover
Why would you think that this law of physics represents a law of nature, rather than thinking that this law represents a description of how the activity of matter is affected by something called gravity?" — Metaphysician Undercover
The fact that laws of physics can be extrapolated, projected, to a time when there was no human beings, doesn't support your claim that these artificial laws represent natural laws. — Metaphysician Undercover
The laws of physics are descriptions with very wide (general) application, so they are generalizations. In order that they are real, true laws of physics, it is necessary that the things which they describe (gravity, Pauli's exclusion, etc.,) are real. There is no need to assume that there is a "law of nature" which corresponds. That is just an ontological assumption. — Metaphysician Undercover
So, your claim is that physics is a species of fiction writing. — Dfpolis
You've obviously misunderstood what I've been saying. I hope that I've made it clearer for you. — Metaphysician Undercover
the footprint (which is what you are measuring) is quite real. — Dfpolis
No it is not, that's the point, it is not a footprint, therefore "the footprint" is not real. — Metaphysician Undercover
No, by my logic his "blue eyes" do not exist. Where's the nonsense in that? — Metaphysician Undercover
I take a ruler and lay it beside something, measuring that thing. Why do you claim that it is necessary for that thing to interact with me in order for me to measure it. — Metaphysician Undercover
I take it that all you mean by this is that what you term "awareness" (which I would call 'reflexive self-consciousness' to distinguish it from animal awareness) cannot be adequately explained in terms of sheer physics? I would agree with that and say that this is also true of biology in general. — Janus
Or are you suggesting that it is part of some separate (supernatural or transcendent) order? If you are asserting the latter, then I can't see how you should not be classed as a substance dualist in the Cartesian sense. — Janus
If reflexive self-consciousness is dependent on, and evolved along with, language, and linguistic capability confers survival advantages (which it obviously does), then I don't see why reflexive self-consciousnesses could not have evolved. — Janus
You have shown me no connection between my understanding that we know the world from a unique perspective, and the possibility of performing counting and/or measuring operations on all that we know. — Dfpolis
Hah. Your replies depend on such diligent misrepresentation of my arguments that it is pointless pushing them further. — apokrisis
So of course the nature of a sign or act of measurement is quite different at each of these levels. — apokrisis
As a scientist, you will know how a logical structuring of your perception results in you literally seeing a different world than before — apokrisis
So you can't escape the fact that all mind is modelling. — apokrisis
You see things "properly" when it comes to natural phenomena, in contrast to the ill-educated layman you were just before. — apokrisis
But it seems - your presentation is confusing - that you are happy to collapse this triadic psychological process to a dualistic mysticism. — apokrisis
We look and we see the data that is there. — apokrisis
The mind has just regressed in familiar homuncular fashion — apokrisis
But what world is this "mind" now in that it can see both inwards and outwards? — apokrisis
As I understand it, to say there is a universal law just is to say that there is a universally invariant form of action, a natural behavior which operates at all times and all places regardless of human awareness and opinion. — Janus
The appearance of gravity is dependent on the existence of mass or energy, therefore it is a property of these things. The occurrence of gravity induced activity is the effect of the existence of these things of which it is a property. The activity is not caused by a natural law. — Metaphysician Undercover
Laws are for us. Nature doesn't need or use them; it just does what it does. Just that. — Pattern-chaser
There is only one reality. If you would reflect on it, you would find that your mind is not only aware of the elephant you are seeing, but the fact that you are seeing it. If you find this puzzling, simply accept it as a contingent fact of reality. — Dfpolis
If it does not fit your theory, then your theory does not fit the facts. — Dfpolis
That is what makes a semiotic approach so epistemically consistent with its ontological claims. I'm surprised you haven't figured that out yet. — apokrisis
There were no actual universals prior to subjects thinking them. — Dfpolis
All of these are intelligible aspects of the molecule, not actual universal ideas. If we could see on hydrogen atom, we could form the universal <hydrogen> — Dfpolis
All of these are real and intelligible, but not actually known until someone becomes aware of them. — Dfpolis
The one fine point here, made by Aristotle in his definition of "quantity" in Metaphysics Delta, is that there are no actual numbers independent of counting and measuring operations. — Dfpolis
So, while counting the hydrogen atoms in a water molecule will always give <2>, there is no actual number 2 floating around the molecule. — Dfpolis
Effectively, you are saying that, regardless of their misguided philosophical beliefs, they practice physics as if there are laws operative in nature. When "They work to ... establish new ones," are they making up the new laws out of whole cloth -- as a fiction writer would -- or are they looking at the results of experiments and observations to see how nature actually operates? If they wish to retain their positions, I am sure they are doing the later. In other words, they are seeking to describe what is. — Dfpolis
Further, when they posit a new or improved law, do they merely see it as describing the results of past experiments and observations, or do they expect it to describe future phenomena? All the physicists I've worked with expect the latter. — Dfpolis
All the physicists I've worked with expect the latter. And if you ask if this is a rational expectation or a baseless faith position, surely they would say it is entirely rational, i.e based on some reason. Certainly they are not such egotists as to think that they, or the description they have formulated, is the reason why nature will continue to operate in accord with the order it exhibited previously. So, despite any errant philosophical views, they expect nature to continue to conform to their description, not irrationally, or because of an extrinsic reason, but for reasons intrinsic to nature -- reasons we call "laws of nature." — Dfpolis
Why do I say that the concept <law of nature> is instantiated here? Because the phenomenon is not a "one of." Similar phenomena, exhibiting the same underlying order, occur through space and time. That is how Newton came to understand that the laws we formulate here, in the sublunary world, are universal -- operative throughout nature. Of course, we can forget Newton's great insight, but then we have no rational ground for thinking we understand the dynamics by which the universe developed or life evolved. If the order we describe here is not universal, anything could have happened at any time -- and we'd never know. It is only by positing that the same laws act now as in the past that we are able to understand the time-development of the universe. — Dfpolis
So, it could be magic? — Dfpolis
Second, I would challenge you to test your suggestion that gravity is not real by stepping off a tall building, but charity prevents me from doing so. Remember, "real" does not mean "substantial." The real need not stand alone. It can be an intelligible aspect of something else. — Dfpolis
I understand that you see the laws of physics as generalizations of past events -- events that are similar, not for any objective reason, but purely by chance. — Dfpolis
The existence of a medium is completely immaterial to the question of interaction. A number of media lay between us, still we are interacting. Media are only relevant to how we are interacting. — Dfpolis
According to current scientific understanding mass warps spacetime, and this is a universal phenomenon which is called 'the law of gravity', or simply 'gravity'. Gravity is not an "appearance" it is an action or effect. The "activity" is not caused by the law, it is the law. — Janus
Laws are for us. Nature doesn't need or use them; it just does what it does. Just that. — Pattern-chaser
We don't invent the law-like behavior of nature. Sure, the Law of Gravity is also a human formulation as well as an invariant natural phenomenon which does not depend on us for its action. — Janus
We don't invent the law-like behavior of nature. — Janus
Sure, the Law of Gravity is also a human formulation as well as an invariant natural phenomenon which does not depend on us for its action. — Janus
I find nothing to disagree with here, unfortunately. — Janus
I would like to note, though, that if mind is considered in the way Spinoza does, as an attribute rather than a substance, and if extensa and cogitans are understood to be incommensurable ways of understanding organic entities, then it would be a category error to say that mental phenomena cause physical phenomena and vice versa: instead there would be a kind of parallelism between them. — Janus
