Yes, I do. I want to know. Are you going to answer?
The basis of most religions in the world is the interaction of the physical and metaphysical. I am a Christian, and that interaction is an important part of faith.

...For more than a decade, physicists have been grappling with the idea of indefinite causal order –instances where it is impossible to tell whether cause came before effect or vice versa, because the two scenarios are in a quantum superposition where both and neither are true at the same time. Strikingly, a 2017 experiment showed that a particle of light can pass through two gates such that it is impossible to tell which it went through first. This further established indefinite causal order as an unavoidable oddity of quantum theory.

“Causality is central to how we explain how things work. We observe things around us and want to ask, ‘Why does that happen?’,” says V. Vilasini at the National Institute for Research in Digital Science and Technology in France.

To investigate causality further, she and Renato Renner at ETH Zürich in Switzerland were informed by two foundational theories. The first is quantum information theory, in which cause and effect are connected by the flow of information. The second is Albert Einstein’s theory of special relativity, which suggests all causal influence must be slower than the speed of light.

This second constraint describes the space-time we live in and bakes into its structure a clear notion of before and after. Experiments that feature indefinite causality happen in that same space-time, yet seem to contradict this structure, says Christina Giarmatzi at Macquarie University in Australia...

...
Arrighi says that staking a definite position on the plausibility of indefinite casual order in any particular experiment may come down to how a researcher interprets quantum theory itself. For Giarmatzi, the issue may only be resolved with more experiments.

However, Arrighi says that the two theorems invite examinations of how relativity and quantum theory can combine. Specifically, the work doesn’t explore what could happen if space-time itself were quantum. This opens the tantalising possibility that within a fully fledged theory of quantum gravity – which physicists have been seeking for decades – causality could once again be in peril.

Personal experience, but my conversion to Christianity is not part of this thread.
Fair enough. I wasn't asking about your conversion, but why one believes something that cannot be proved.

If your personal experience contributes to your belief, aren't you at least, in principle, saying that those unprovable things can have evidence? Would it not be the case that a cumulative collection of evidence would "prove" the unprovable?

It seems to me that you think you have enough evidence, in which case you don't believe the "unprovable".

After the experiencing the “way of salvation” as described in many places on this forum. I experienced a real change of heart. My desire to learn more about God, study the Bible, and live, as best I could, in a way that was more pleasing to God, increased significantly. I also experienced what I would consider a personal relationship to God, which included prayer, guilt when I got it wrong, and a greater love for my fellow human beings. It also increased my courage to do what is right without regard to what others thought about me. I am far from perfect and consider myself as under construction, but the change in direction was obvious to me.

It seems to me if we aren't committed to physicalism,

Physicalism?



I'm sorry @Fervent ,just from context the term "physical" seems to mean something different from what I know....

Can you define it here?

All four of these can be true with no inconsistency. So do we have enough evidence for non-physical causes yet, or do we still want to insist that the natural iis physical?

Only if we presume that reality is fundamentally physical. What this argument is meant to accomplish is to ask the question whether or not we need that presumption to do science.
It depends on whatever you mean by physical.

For example...



Are we talking about mass, energy, or what?


If we can restate closure in a metaphysically neutral way and remove metaphysical assumptions, and doing so improves our explanations, why preserve the metaphysical assumption?

You still have a problem of criterion.







No, simply that the notion that the world is fundamentally physical is suspect

In what way?



and that physicalism is the issue in the mind-body problem.

Why do you think the mind-body problem is still a problem? Has any evidence of the mind being physically produced by the brain come into reality?

If there is any argument at all, its that we have had evidence for mental causation all along but physicalist metaphysics

Where's the evidence for mental causation?

I was surprised to learn some people cannot think in pictures.

I was more surprised to learn some people only think in pictures and have no internal monologue...or dialogue.

If you'll indulge me.....at what number of people do they begin to look indistinguishable from one another (a fuzzy distant crowd) or a series of hard to picture individuals who begin repeating? I can try really hard....but somewhere around two dozen or so...the clear pictorial representation is gone and replaced with a literal number.

It's an upper limit on what seems like it should be easy. You?

I'm asking because if I'm 100% honest...I don't see any mind-body problem. I've seen people describe it....I understand the words....and at the end they claim "that's the mind body problem" and at no point do I see any problem.

If anyone feels like they really get it....please explain as simply as possible.

It doesn't matter what it sounds like. Empirical means drawn from experience, it's the definition of the word. But this isn't a question about the data, it's about hidden premises snuck into the closure principle.

I'm unsure what the "closure principle" is....

But yes...empirical refers to the observable world. In modern usage, the testable, the measurable, the experimental, etc.



Atheist's aren't skeptics, though.

Ok.


They settle for the world and then refuse to dig any deeper.

I'll also concede to the theoretical, conceptual, emotional, and purely abstract. We can describe these things....we can put them into practice....but their relationship to truth appears subjective until successfully applied to the empirical reality. At that point we can say with at least some confidence they're objective.



You've made an unjustified assumption. Why'd you stop there?

What's a justified assumption in your mind?

I start with something that can't possibly be false.

Regarding the entirety of what can be true and false....you've identified something that cannot possibly be false?

Yeah, and my question is why do you need the word physical if you're identifying the same thing?

I'd argue we don't...but as neither of us created the English language it's not a substantive question.

The value is in the resolution of a discrepancy in observations.

I still don't understand what discrepancy you keep referring to.

The disappearance of the inconsistency which allows the four propositions to stand together without conflict.

Which one or one's are in conflict?


If they were the same thing nothing would change by shifting terms around. But something changes when we do. So they don't mean the same thing. As atheists love to trot out:do not multiply entities needlessly.

I've never heard that before. I've never heard your 4 propositions before.


If we only mean by physical that it is natural, then there is no need for a different term.

All things physical may be natural but that doesn't necessarily mean all things natural must be physical.

I wouldn't call an absolute vacuum physical but I would call it natural.

I wouldn't call darkness physical though I would call it natural.

You're conflating categories.

You can't just say nature is nature.

Nature is nature.

I hope this helps.

#2.



Specifically, attempting to describe the #2 belief accurately.



I think the assumption of an external independent reality must be made....otherwise it's unclear what the scientific method is for.

In your religion....what is the interaction between the physical and metaphysical?

.. Specifically, attempting to describe the #2 belief accurately.
Accurately with respect to what? The belief in the assumption of an external independent reality?
Pfft! So much for the meaning of that kind of 'accuracy'! (IMO).

The scientific method was developed to be useful. That's it .. that's all.
Anything piled on top of that, is just philosophical baggage that typically ends up just getting in the way of that purpose .. (like the untestable belief in the existence of a mind independent reality).

I see logic as nothing more than the describable limitations of language.

And you came by this view about "Logic" via which sources and influences? Wittgenstein, perhaps? I'm perusing the textbooks I have on formal and informal Logic and I'm not quite seeing how they are merely presenting nothing more than the describable limitations of language. There's a bit more there than that .........................

I sure hope you're not referring to the other, prior Logical Positivists. Because they contradicted themselves.

"It"???
I couldn't care less about accurate descriptions of what people believe in .. because beliefs are of no use in scientific thinking.
Useful for what?
For goodness sake! You have no idea what useful contributions science has made?
Gimme a break!

Uhhhh....thinking about it really hard, influenced by the consideration of certain logical paradoxes.



Wittgenstein, perhaps?

Nope. Never read any Wittgenstein....though obviously, it's unlikely I'm the first to have an idea.


Right...well whatever you consider the basis of logic, it's clear to me that it's basis is rooted quite literally in the language we use. Let's take one of the most basic and uncontroversial laws of logic as an example....

The law of non-contradiction.

Two contradictory statements cannot be true in the same time in the same way.

Formally A cannot also be not -A.

While formal logic is fun...it's not really how we describe the world. The law describes categorical sets like inside and outside. One cannot be inside a room in the same way at the same time as they are outside a room.

What if we imagine someone standing exactly in a doorway to the room though....half inside, half outside? Are they not both inside and outside the room in the same meaning of those words at the exact same time? Both inside and not inside at the same time? Both outside and not outside at the same time?

Fortunately, a third categorical set was created to describe such things..."at the threshold" between between inside and outside....and it was the linguistic creation of the third category which describes the truth of something or someone at the threshold of two or more contradictory states.
