Reality (General)

by dhw, Thursday, August 08, 2019, 13:06 (446 days ago)

A review in The Sunday Times has prompted me to write this post. The book is called
The Case Against Reality - How Evolution Hid the Truth from Our Eyes

The author is Donald D. Hoffman, a professor of cognitive science at the University of California.
It is unfair to judge a book when you’ve only read the review, and so my comments only concern remarks made in the review.

QUOTE: “Consider a tomato. One right in front of you. Hoffmann argues that we usually believe the tomato is there because we can see, smell, taste and touch it. But if you test that belief, he says [……] you will realise you are wrong. “Something is there”, but it is certainly not a tomato, and indeed “not any object in space time”. This idea, Hoffman says, “sounds faintly mad…”

I disagree. I think it sounds totally mad. So too does the claim that “your very sense that you are living inside space and moving through time…is an evolved illusion. Space and time are not underlying realities, they are “simply the format of our interface” with whatever reality is.” This to me is all a reductio ad absurdum of the indisputable fact that perception is a subjective process. Let us take that for granted, and let us by all means conclude that we cannot know what constitutes objective reality. But firstly, that does not mean there is no such thing as objective reality: it simply means that we can never be sure that our perception of something corresponds to that reality. Secondly, the word “tomato” has been invented by us English-speaking humans to denote a particular object. The tomato could have been called peach or banana or hoffman, but we have settled on “tomato” and there is a general consensus among us that the word denotes this particular object. It most emphatically does NOT mean that the object itself does not exist, and yes indeed, all our senses and experiences tell us that it does – or did, until we’ve eaten it. Is there really some superior criterion to these that can establish the non-existence of the object, and indeed of ourselves?

Thirdly, “space” and “time” are also human terms invented to describe what we move through. If someone tells me that moving from one place to another and that movement from cause to effect are both illusions, my stock answer is to invite him/her to step in front of a bus. The fact that in time (I choose the expression deliberately) neither I nor the bus will exist does not alter the objective reality of our both having existed in the past. It simply means that objective reality is not only subjectively perceived but is also constantly changing as it moves through the phases which we humans have called past, present and future, and cause and effect.

QUOTE: “All this time we have been wondering how consciousness emerges from physical reality, he says, when the real problem is how reality emerges from consciousness.”

Does he truly believe that the sun and stars and Planet Earth did not exist until we humans arrived to perceive them? If consciousness is “real”, then is the being who has consciousness unreal, and do all the things that consciousness is conscious of have no reality? His answer is presumably yes. So why the heck did he write his unreal book to be read by unreal readers sitting in unreal armchairs and subsequently writing unreal comments about it? Sadly, this is not tongue-in-cheek philosophy. I recently went to a funeral, and after the palpable and all-too-real emotions of the occasion, I met a student who is writing a thesis on this very subject, and was wildly enthusiastic about the theory that even my proverbial bus, let alone the widow’s grief, was not real. She regaled me with computer images and technical terminology to illustrate the point that although we agreed that she was lecturing me, she was not even there to lecture me, and I was not there to listen to her.

To sum it all up, I propose that there IS such a thing as objective reality, we can never be sure of its true nature, but anyone who claims that reality is created by consciousness and has no existence outside our consciousness should step...But no, I shan’t repeat the invitation. I can only hope they won’t accept it.

A brilliant rejection of the point of the book. Reality does not require our existence, but our brain certainly helps us in appreciating it. And no computer will ever have consciousness, although some computer simulations do advance scientific findings. The young student is filled with the exuberance of youthful discovery.

As for the title of the book, the author seems to feel that evolution evolved a brain with which to fool us? Evil evolution!

DHW (Perception is a subjective process and we cannot know what constitutes objective reality) that does not mean there is no such thing as objective reality: it simply means that we can never be sure that our perception of something corresponds to that reality.

This statement feels off to me...not wrong necessarily, just incomplete, and I'd like to pick this apart a bit before I tackle the other. I work through it as I write, though, which is why my arguments seem a bit....fuzzy sometimes.

Agreed - Perception is a subjective process.
Agreed - There is such a thing as objective reality.
Agreed - We can never be sure that our perception agrees with objective reality. (Being partially color-blind and aware of it, this is consciously embodied in my every day life.)

And this is where it feels incomplete. We can never be 100% certain that our perception agrees with objective reality or any other perceived reality. This would mean that objective reality and perceived reality are separate AND unequally valid realities. Objective reality differs in the fact that it can operate absent OUR mind, which means that the mind behind it is on a different, higher in terms of complexity, level of existence. It is different in degree and magnitude but NOT by type.

We know that the structure of the brain and the universe are very similar. We know that they both have complex physical structures of deeply complex relationships and nested hierarchies of scale and influence.

Universe > Galaxy > Solar System > Planet > Geological Scale > Human Scale > Cell > Molecule > Atom > Sub-Atomic Particles.

Body > Brain > Hemisphere > Region > Neuron/Synapses > Cell Bodies >

I am certain I am missing some scales and this is a gross oversimplification. Feel free to add/reclassify. The interesting thing is that these nested structures exist both internal and external to what we would classify as living creatures AND in non-living system. It is also interesting that the relationship structure is bi-directional. Each structure spreads influence up and down the chain. This, of course, suggest communication up and down the chain.

In molecular biology, we see this in chemical and electrical signaling between cells. In the physical world, we see this in terms of energy and motion, but, and here is the point, we never look at it in terms of communication. What is being communicated, and is it being communicated in a language we can comprehend? If we could comprehend it, could we communicate with it?


Despite what you might think, this is not a call for God. But rather, a call to look at the similarities between the systems and see if any avenues for research could be inferred.

This is a really stimulating post – as ever – and I shall cherry-pick for the sake of brevity and clarity.

TONY: We can never be 100% certain that our perception agrees with objective reality or any other perceived reality.

I don’t know why “objective reality” cannot include all the realities that we perceive.

TONY: This would mean that objective reality and perceived reality are separate AND unequally valid realities. Objective reality differs in the fact that it can operate absent OUR mind…[dhw: fine with me up to this point]… which means that the mind behind it is on a different, higher in terms of complexity, level of existence. It is different in degree and magnitude but NOT by type.

You say later that “this is not a call for God”, but what else could it be if you say there is a mind behind it? We simply do not know if there is a mind behind it. Objective reality might simply be the materials that make up the universe and operate just as we see them operating. However, if there is a mind, I have no objections at all to it being different in degree and magnitude but NOT by type. It makes perfect sense to me that a God would have attributes in common with the humans he has been instrumental in creating – though this is anathema to David.

TONY: We know that the structure of the brain and the universe are very similar. We know that they both have complex physical structures of deeply complex relationships and nested hierarchies of scale and influence.

Universe > Galaxy > Solar System > Planet > Geological Scale > Human Scale > Cell > Molecule > Atom > Sub-Atomic Particles.
Body > Brain > Hemisphere > Region > Neuron/Synapses > Cell Bodies >

I love this. I also see the body as a microcosm of the universe, in which all individual parts combine to form a functioning whole.

TONY: It is also interesting that the relationship structure is bi-directional. Each structure spreads influence up and down the chain. This, of course, suggest communication up and down the chain. (dhw’s bold. See below.)

In molecular biology, we see this in chemical and electrical signaling between cells. In the physical world, we see this in terms of energy and motion, but, and here is the point, we never look at it in terms of communication. What is being communicated, and is it being communicated in a language we can comprehend? If we could comprehend it, could we communicate with it?

This is where I become partially sceptical. Of course I agree that molecular biology requires communication, but I’m far from convinced that the physical world of energy and motion “communicates”. Communication as you have described it requires a conscious effort on both sides (use of some kind of language, as you say), but influence doesn’t. A rock falling on my head may have a profound influence on me, but in all honesty, I do not believe the rock is making any attempt at communication. You can expand this to universal proportions. An atheist will no doubt claim that the combination of materials of which we are composed has come about through mindless mixing, and the sun is not deliberately and consciously giving us life and threatening us with death, and the wind doesn’t use any form of language when it blows down the tree. The vagueness of your conclusion below suggests to me that you are just as aware of this as I am:

TONY: Despite what you might think, this is not a call for God. But rather, a call to look at the similarities between the systems and see if any avenues for research could be inferred.

I don’t think the type of similarity you are looking for can dispense with God, unless perhaps you are considering some form of panpsychism (i.e. all matter has a degree of…let’s call it quasi-consciousness), but I’ll be very interested to read your response to this, as I’m not convinced that I’ve grasped the whole of your argument.

Not 'anathema' to me. What is anathema is trying to attribute human mental traits to God. Some or all may exist, but all we can do is guess.

Well, not precisely. Chemical communication does not require a consciousness, just something that can interpret the signal. If non-biological communication does exist, it certainly varies in degree, just as biological signalling does.

I'm not sure I grasp it all right now. So often these things sit on the edge of my ability to articulate for quite some time. I think in some way, I am questioning our way of looking at the universe. We have it clumped as organic and inorganic, living and non-living, and everything non-living is just big dumb dirt. But our dumb dirt is, in its own way, just as rich and complex as living creatures. I am still trying to work through it. I will try to argue it more clearly later.

And I am not claiming that it is, any more than we claim that our cells are. However, our dumb unconscious cells somehow work together to produce, or at least support, consciousness. If it is possible that our dumb cells do it, why is it impossible on a higher level?

TONY: It is different because it exists independent of us and is not subject to our subjective interpretations. Our personal realities are objective reality overlayed with our own filters and perceptions.

Yes, of course. We are all agreed that our perception is subjective and limited. I was simply pointing out that Tony’s original comment doesn’t quite make sense: “we can’t be certain that our perception agrees with...any other perceived reality.” There are realities that we perceive and realities that we do not perceive. “Objective reality” must include all the realities that we do perceive, even though we perceive them subjectively. Or are you referring to imagined "realities" which we think we perceive but may be figments of our imagination? That = we can't be certain that our perception agrees with things that might not have any objective reality. (God would be an example.) It's all getting too complicated!

TONY: This would mean that objective reality and perceived reality are separate AND unequally valid realities. Objective reality differs in the fact that it can operate absent OUR mind…[dhw: fine with me up to this point]… which means that the mind behind it is on a different, higher in terms of complexity, level of existence.

But you didn’t ask a question in your original post. You simply referred to “the mind behind it”, which is “on a different..level of existence”. The question you are now asking gets to the nub of the matter: Is there a mind behind it (e.g. God, or some kind(s) of panpsychist consciousness) or is physical reality nothing but mindless materials swirling around in mindless space?

dhw: However, if there is a mind, I have no objections at all to it being different in degree and magnitude but NOT by type. It makes perfect sense to me that a God would have attributes in common with the humans he has been instrumental in creating – though this is anathema to David.

DAVID: Not 'anathema' to me. What is anathema is trying to attribute human mental traits to God. Some or all may exist, but all we can do is guess.

Of course we can only guess at his nature and his purposes (not to mention his existence), but it is anathema to you if someone guesses at either of these unless it is your guess, which is that he is always in control and is purposeful, and his one and only purpose in creating life was to produce H. sapiens, and he specially designed billions of non-human life forms, lifestyles and natural wonders (like the remarkable jumping larva of the golden rod gall midge) only so that they could eat or be eaten by one another until he could specially design the only thing he wanted to design: H. sapiens. You even guessed yourself once that his purpose in specially designing all these wonders (if he did design them) could have been to enjoy his own work, like a painter enjoying his paintings. But for some reason you have a fixed belief in the "eat or be eaten" guess.

DAVID: This is the point I keep making: cells make chemical signals which do not require a conscious interpretation, but just an automatic chemical response.

David wrongly attributed Tony’s comment to me. We are talking about molecular biology, and lots of organisms use chemical signals to communicate. These include bacteria, which are single cells. Many scientists agree that they are sentient, communicative, cooperative, decision-making, and therefore intelligent. Of course their “consciousness” is not comparable to ours, but David’s theory that 3.8 billion years ago his God preprogrammed every single bacterial response to every single new problem for the rest of time seems to me less likely than the (theistic) theory that his God gave them the intelligence to work out their own solutions.

Then you are clearly thinking your way into some kind of panpsychism (which of course does not exclude a God).

DAVID: I strongly doubt dumb dirt is in any way conscious.

TONY: And I am not claiming that it is, any more than we claim that our cells are. However, our dumb unconscious cells somehow work together to produce, or at least support, consciousness. If it is possible that our dumb cells do it, why is it impossible on a higher level?

I object to the assumption that our cells are dumb and unconscious (see above), although no one knows the source of consciousness. Clearly there are different levels of consciousness, but I share David’s doubts about dumb dirt, and even about rocks and waters and stars and gases having any level of consciousness. However, life and consciousness are either the result of top-down creation (God) or bottom-up evolution (the most rudimentary consciousness, formed by chance and evolving to higher levels). I myself am unable to choose between the two. Whatever may be the objective reality is beyond the reach of my subjective perception - and also of my subjective powers of interpretation!

PART TWO

dhw: This is where I become partially sceptical. Of course I agree that molecular biology requires communication, but I’m far from convinced that the physical world of energy and motion “communicates”. Communication as you have described it requires a conscious effort on both sides (use of some kind of language, as you say), but influence doesn’t.

TONY: Well, not precisely. Chemical communication does not require a consciousness, just something that can interpret the signal. If non-biological communication does exist, it certainly varies in degree, just as biological signalling does.

DAVID: This is the point I keep making: cells make chemical signals which do not require a conscious interpretation, but just an automatic chemical response.

dhw: David wrongly attributed Tony’s comment to me. We are talking about molecular biology, and lots of organisms use chemical signals to communicate. These include bacteria, which are single cells. Many scientists agree that they are sentient, communicative, cooperative, decision-making, and therefore intelligent. Of course their “consciousness” is not comparable to ours, but David’s theory that 3.8 billion years ago his God preprogrammed every single bacterial response to every single new problem for the rest of time seems to me less likely than the (theistic) theory that his God gave them the intelligence to work out their own solutions. This would also apply to our own cell communities which at some time in the past cooperated to produce every individual organ in our bodies, and which continue (now mainly automatically) to cooperate in enabling those organs to function. (See also below.)

And I reply it all can be automatic, based on instructions the organisms or cells carry.

dhw: However, if there is a mind, I have no objections at all to it being different in degree and magnitude but NOT by type. It makes perfect sense to me that a God would have attributes in common with the humans he has been instrumental in creating – though this is anathema to David.

DAVID: Not 'anathema' to me. What is anathema is trying to attribute human mental traits to God. Some or all may exist, but all we can do is guess.

dhw: Of course we can only guess at his nature and his purposes (not to mention his existence), but it is anathema to you if someone guesses at either of these unless it is your guess, which is that he is always in control and is purposeful, and his one and only purpose in creating life was to produce H. sapiens, and he specially designed billions of non-human life forms, lifestyles and natural wonders (like the remarkable jumping larva of the golden rod gall midge) only so that they could eat or be eaten by one another until he could specially design the only thing he wanted to design: H. sapiens. You even guessed yourself once that his purpose in specially designing all these wonders (if he did design them) could have been to enjoy his own work, like a painter enjoying his paintings. But for some reason you have a fixed belief in the "eat or be eaten" guess.

My fixed belief is supported by the history we have uncovered. Humans are the current and possibly the last endpoint, and everyone has eaten or been eaten since the beginning. My fixed reason is entirely based on fact and logic.

I agree with most of DHWs comments here (though not having read either the book or the review). Where I differ slightly is in the nature of "objective reality". The evidence from modern quantum science appears to be that on the smallest scales reality becomes rather "fuzzy". So any objectivity can only be of a probabilistic or statistical kind.

In a later comment DM suggests "We know that the structure of the brain and the universe are very similar". However, the only similarity I can see is that they can both be regarded as complex systems, but they are systems of very different kinds. The structure of a brain is like a network of linkages, whereas the universe is a distribution of bodies (from subatomic particles to clumps of galaxies) rather loosely held together by various forces.

A strange combination of Davidian beliefs. Firstly, if you agree that a collision between buses and humans is a genuine form of reality, with all its dire consequences, why do you think that “quantum fuzziness”, a wonderful description of the current state of quantum mechanics, is the basis of reality? Secondly, you cannot escape the fact that quanta are material, and yet you believe that the basis of reality is an immaterial God made of “pure energy”, and our consciousness is an immaterial blob of his consciousness. I find this bewildering.

Under “consciousness

dhw: We are discussing the origin of consciousness and your proposal that “everything is material at the basis of the universe”, whereas in fact you believe that the basis of the universe and of consciousness is immaterial, in the form of “pure energy”. I went on to say I found both concepts equally difficult to believe in as the source of life, consciousness and the ability to reproduce and evolve. You asked if there was a third option, and I said this was panpsychism, but this can be used to support atheism as well as theism. I do not support or “look to” any of these three options as credible solutions to life’s mysteries, which is why I remain agnostic, while acknowledging that at least one of them must be nearer the truth than the others.

DAVID: I think my supposition of an eternal pure energy as the source of everything is a reasonable possibility. we don't know what is on the other side of quantum uncertainty.

I suspect that George will find it even more reasonable to argue that the source of everything is material, but I eagerly await his own comment. I will stick to the fact that material reality is the only reality we would all agree on (bus smashes into quantum theorist and splatters him all over the road), and since we don’t know what is on the other side of all the things we are uncertain about, the most “reasonable” approach is that of the agnostic, who candidly admits that he doesn’t know and therefore can’t choose between the different theories.

GEORGE: I don't think I've heard of this theory that "intelligent cells or cell communities" have "their own special form of consciousness" that guides their evolution before, but it sounds rather like reviving elan vital or a form of pan-psychism. It seems to me that postulating such things without proof is unnecessary, since natural selection is adequate.

Particles, but we do not understand the behaviour of individual particles, which is why quantum mechanics is fuzzy. We do understand the behaviour of particles combined into one solid mass such as a bus or a quantum theorist who steps in front of the bus. Why then do you consider material behaviour you don’t understand as “the basis of reality”, and material behaviour you do understand as somehow not being the basis of reality? But then you take the whole discussion one step further:

DAVID: I think there was primordial energy before quanta appeared as God created the universe.

So now we have two forms of reality: one immaterial, which is your God’s reality, and one material, which is “our reality", but according to you the basis of our material reality is fuzzy, despite the unfuzzy and undisputed reality of the bus. Furthermore, you say “we don't know what is on the other side of quantum uncertainty”, which leaves your immaterialism as open to refutation as materialism (good grounds for agnosticism).

DAVID: The bus is not quantum mechanics, and is a very poor example of a refutation. Our consciousness plays a role in the strange results.

Of course everything we consider as matter consists of tiny particles, and materialists will tell you that they and their behaviour constitute reality. However, firstly that does not mean that the fuzzy behaviour of individual particles when observed by conscious minds is more objectively “real” than the anything-but-fuzzy behaviour of particle communities such as a bus when observed (or even unobserved) by conscious minds. Secondly, although of course consciousness, ideas, thoughts, dreams, the will, aesthetics, philosophy etc. are immaterial, the issue is whether they are produced by particles or by some unknown reality “on the other side of quantum uncertainty”. You opt for an unknown reality, and so you argue on two levels, which amounts to saying that the basis of material reality is particles (which no one will dispute) but the basis of the behaviour of material reality is immaterial reality, which is wide open to dispute.

dhw (to David:) "... if you agree that a collision between buses and humans is a genuine form of reality, with all its dire consequences, why do you think that “quantum fuzziness”, a wonderful description of the current state of quantum mechanics, is the basis of reality?"

GEORGE: The fuzziness only becomes significant on very small, molecular and sub-atomic scales. On the scale of humans and buses it is negligible.

dhw: Which is why I consider it absurd to assert that quantum mechanics is the basis of reality.

DAVID: But what is everything made of at the smallest levels?

d hw: Particles, but we do not understand the behaviour of individual particles, which is why quantum mechanics is fuzzy. We do understand the behaviour of particles combined into one solid mass such as a bus or a quantum theorist who steps in front of the bus. Why then do you consider material behaviour you don’t understand as “the basis of reality”, and material behaviour you do understand as somehow not being the basis of reality? But then you take the whole discussion one step further:

DAVID: I think there was primordial energy before quanta appeared as God created the universe.

dhw: So now we have two forms of reality: one immaterial, which is your God’s reality, and one material, which is “our reality", but according to you the basis of our material reality is fuzzy, despite the unfuzzy and undisputed reality of the bus. Furthermore, you say “we don't know what is on the other side of quantum uncertainty”, which leaves your immaterialism as open to refutation as materialism (good grounds for agnosticism).

And neither you nor I know what is on the other side of the wall of uncertainty, so how do you refute what might be over there? You squabbled with Ruth Kastner as you didn't understand what she was trying to do. Remember Feynman told us no one understands quantum theory.


DAVID: The bus is not quantum mechanics, and is a very poor example of a refutation. Our consciousness plays a role in the strange results.

dhw: A refutation of what? Do you or do you not agree that the bus is an example of the only reality you, George and I will certainly accept as being as close to objective as we can get? The fact that our consciousness plays a role in the strange results of quantum mechanics is a very poor example of a refutation of the reality of the bus. And while we’re at it, are you now arguing that quantum mechanics is the basis of our consciousness, i.e. that it is NOT immaterial but arises from material particles? Or is our consciousness not part of “our” reality?

DAVID: I repeat that the basis of everything we consider matter is quantum particles at the tiniest level. Consciousness is immaterial as we know, but it plays a large role in quantum experiments. I conceive of it as pure energy, not in material form.

dhw: Of course everything we consider as matter consists of tiny particles, and materialists will tell you that they and their behaviour constitute reality. However, firstly that does not mean that the fuzzy behaviour of individual particles when observed by conscious minds is more objectively “real” than the anything-but-fuzzy behaviour of particle communities such as a bus when observed (or even unobserved) by conscious minds. Secondly, although of course consciousness, ideas, thoughts, dreams, the will, aesthetics, philosophy etc. are immaterial, the issue is whether they are produced by particles or by some unknown reality “on the other side of quantum uncertainty”. You opt for an unknown reality, and so you argue on two levels, which amounts to saying that the basis of material reality is particles (which no one will dispute) but the basis of the behaviour of material reality is immaterial reality, which is wide open to dispute.

The dispute is really your problem. The more we dig down into tiny particles the more confusing it gets. But we cannot ignore what we do not understand as you keep trying to imply.

You do not understand me. My point is that you are proposing two forms of reality: one material and one immaterial. Quantum mechanics can only deal with material reality, and the behaviour of material particles appears to contradict the material reality represented by the bus. In my view, it is absurd to argue that the incomprehensible behaviour of individual particles of matter is more real than the comprehensible behaviour of the masses of particles that make up the bus. You have added a different form of reality: an immaterial God in the form of pure energy, hiding behind the quantum wall of uncertainty. My point is that I find it impossible to draw any such conclusions concerning a subject about which we know nothing.

Thank you for repeating my argument: the bus is real, and the problem is the incomprehensible behaviour of the individual particles. But you regard the incomprehensible behaviour of the particles as being more real than the bus. Of course sitting on the fence does not solve the problem: I sit on the fence BECAUSE the problem has not been solved! I have absolutely no problem, however, with the conclusion that consciousness is at play in our reality: we agreed long ago that we cannot “know” what objective reality is because all our perceptions of it are subjective, i.e. images created by our consciousness. But as I keep saying, the fact that our perceptions are subjective does not mean that what we perceive is not objectively real. Hence the bus test.

Why shut your mind to the problem of incomprehensibility? Perhaps understanding God's method will help us understand God.

My view of quantum reality is not your view. When we study basic real particles that make up, and underlie our reality (the bus), we find they do strange things we do not understand. We both agree on this. What Kastner and I am trying to tell you is simply that the physics of the quantum particles is a different form of reality than we appreciate in our 'Big" world. And that different form of reality creates our reality. An example: tickling a particle in Madrid makes a particle in the Azores change in the same way. Another example: late choice experiments change the result of an experiment after the event, meaning consciousness is part of the process!!! The same particles make up your bus. There are obviously two realities, one the basis of the other. Both real with one responding to consciousness. I can suggest books to read, but I know you do not have the time. Like Feynman said, shut up and calculate, because hat is all you can do. Accept what I (and Kastner) have told you, because that is all you can do, or read the books and learn. The bus is fooling you.

You have ignored the latter hypothesis, and continue to focus on what I have already accepted, but you brush aside the whole basis of my disagreement with Kastner over the claim that quantum reality, which we do not understand, is more real than the bus reality we know.

DAVID: And that different form of reality creates our reality. An example: tickling a particle in Madrid makes a particle in the Azores change in the same way. Another example: late choice experiments change the result of an experiment after the event, meaning consciousness is part of the process!!! The same particles make up your bus. There are obviously two realities, one the basis of the other. Both real with one responding to consciousness.

I have not disputed any of this, except that I jib at the argument that quantum mechanics is the basis of or creates our reality, since the combined particles that make up the bus behave in a totally predictable manner. I have even expanded your last remark by pointing out that all forms of our reality are dependent on the subjectivity of our conscious perception. The nearest any of us can come to objective reality is by consensus, and consensus has it that the behaviour of the combined particles of the bus and of the quantum theorist who steps in front of it denotes an explicable and predictable reality. That is why I dispute the claim that the inexplicable, unpredictable reality of quanta is more real than that of the bus. You have encapsulated the whole dispute with your very last comment:

More fool you if you think so. And, dear friend, I beg you not to step in front of it.

Reality

by David Turell @, Friday, November 15, 2019, 18:50 (347 days ago) @ dhw

DAVID: My view of quantum reality is not your view. When we study basic real particles that make up, and underlie our reality (the bus), we find they do strange things we do not understand. We both agree on this. What Kastner and I am trying to tell you is simply that the physics of the quantum particles is a different form of reality than we appreciate in our 'Big" world.

dhw: That is obvious since, unlike the bus, individual particles behave in a manner we do not understand. You wrote: “When we get down to the basis of reality we bump into the unreality of quantum actions by the weirdness of what the particles do.” I replied: "Why are you now calling quantum actions unreal? They are part of the material world, and I accept the scientists’ discoveries, but since science cannot explain these actions, I refuse to accept that they are more real than the explicable behaviour of the combined particles of the bus! [...] And quantum reality is not a separate reality because it is an incomprehensible part of the material world.

You have ignored the latter hypothesis, and continue to focus on what I have already accepted, but you brush aside the whole basis of my disagreement with Kastner over the claim that quantum reality, which we do not understand, is more real than the bus reality we know.

Note my bold above. Both the weird particle activity and the bus are obviously real, but the unreal activity of the particles create the bus that can crush you. The particles we are discussing are not represented by the bus. They are the bus but in a different form. They are part of our reality while we don't understand as to how they create our recognizable reality. Your bus is a terrible analogy in view of the difference.

Your bus is dangerous. but does not represent the quantum research that you have trouble with. Note the bold above. When we beat up the materials that makes the bus, what we left with are particle and their behavior we do not understand. Those particles are the raw materials that create the materials that make up the bus. They are the basis of the bus, but in dealing with the bus we are in our reality while the creating particles are part of our reality we do not understand and therefore may not operate in our realm (portion) of reality. I am comfortable compartmentalizing the two regions, as Kastner was. Both regions are just as real as you want, but vastly different.

"But in a paper recently published in Science Advances, we show that, in the micro-world of atoms and particles that is governed by the strange rules of quantum mechanics, two different observers are entitled to their own facts. In other words, according to our best theory of the building blocks of nature itself, facts can actually be subjective."

I know all about the confusion, which is why I object to definitive statements about the basic role played by quantum mechanics in the creation of our everyday reality, and a few days ago I pointed out that nobody knows what “objective” reality consists of because our perception of it is always subjective; the nearest we can come to objectivity is consensus. And consensus has it that the behaviour of the bus and of the quantum theorist it hits is as close to objective reality as we can get.

"Can Science Rule Out God?
"We must understand the laws of nature before we can deduce their origins

***

"Is the universe infinite and eternal? Why does it seem to follow mathematical laws, and are those laws inevitable? And, perhaps most important, why does the universe exist? Why is there something instead of nothing?

***

"Einstein often invoked God when he talked about physics....He was clearly awed by the laws of physics and grateful that they were mathematically decipherable. (“The eternal mystery of the world is its comprehensibility,” he said. “The fact that it is comprehensible is a miracle.”)

***

"Although quantum theory is now the foundation of particle physics, many scientists still share Einstein’s discomfort with its implications. The theory has revealed aspects of nature that seem supernatural: the act of observing something can apparently alter its reality, and quantum entanglement can weave together distant pieces of spacetime. (Einstein derisively called it “spooky action at a distance.”) The laws of nature also put strict limits on what we can learn about the universe. We can’t peer inside black holes, for example, or view anything that lies beyond the distance that light has traveled since the start of the big bang.

***

"Cosmologists don’t know if the universe even had a beginning. Instead it might’ve had an eternal past before the big bang, stretching infinitely backward in time. Some cosmological models propose that the universe has gone through endless cycles of expansion and contraction. And some versions of the theory of inflation postulate an eternal process in which new universes are forever branching off from the speedily expanding “inflationary background.”

"But other cosmologists argue that inflation had to start somewhere, and the starting point could’ve been essentially nothing. As we’ve learned from quantum theory, even empty space has energy, and nothingness is unstable. All kinds of improbable things can happen in empty space, and one of them might’ve been a sudden drop to a lower vacuum energy, which could’ve triggered the inflationary expansion.

***

"Scientists don’t fully comprehend the quantum world yet, and their hypotheses about the first moments of Creation aren’t much more than guesses at this point. We need to discover and understand the fundamental laws of physics before we can say they’re inevitable. And we need to explore the universe and its history a little more thoroughly before we can make such definitive statements about its origins.

"Just for the sake of argument, though, let’s assume this hypothesis of Quantum Creation is correct. Suppose we do live in a universe that generated its own laws and called itself into being. Doesn’t that sound like Leibniz’s description of God (“a necessary being which has its reason for existence in itself”)? It’s also similar to Spinoza’s pantheism, his proposition that the universe as a whole is God. Instead of proving that God doesn’t exist, maybe science will broaden our definition of divinity.

***

"The pivotal role of observers in quantum theory is very curious. Is it possible that the human race has a cosmic purpose after all? Did the universe blossom into an untold number of realities, each containing billions of galaxies and vast oceans of emptiness between them, just to produce a few scattered communities of observers? Is the ultimate goal of the universe to observe its own splendor?

"Perhaps. We’ll have to wait and see."

Comment: A thoughtful review. I still feel a full understanding of quantum dynamics is required. The whole article is worth reading and the author is agnostic.

Not really says Egnor:

https://evolutionnews.org/2020/01/can-science-answer-all-the-big-questions/

"The claim that science is the only way to answer all the big questions is itself not a scientific claim — it is an epistemological claim. The assertion that science can answer all questions is self-refuting. The assertion itself is not science.

"There are three ways we can know something about reality. We can perceive it with our senses — the coffee cup on the table in front of us, for example. Or we can infer something by a priori logical reasoning. Much of mathematics is like this.

"The third way is by a posteriori reasoning, which is inferential reasoning. A posteriori reasoning follows this pattern: we collect evidence about things that exist, and via a logical or mathematical process of reasoning we infer a truth about existence. This is the scientific method. This is also natural theology, which is the branch of theology that proves God’s existence using evidence and reason. It is distinguished from revealed theology, which deals with truths about God that are known from Scripture, tradition, etc.

"Natural theology is science. It is exactly the same kind of knowing that is used routinely in natural science. For example, consider our scientific knowledge about the Big Bang. We collect evidence (the red shift, cosmic background radiation, etc.), and by a process of reason and logic (Einstein’s general relativity, etc.) we conclude that the universe began as a singularity 14 billion years ago. It’s good science — solid a posteriori reasoning.

"Now consider one of the many strong proofs of God’s existence — Aquinas’ Second Way. We collect evidence (the fact that there are chains of essentially ordered causes in the universe), and by a process of reason and logic (the metaphysics of potency and act and Aristotle’s Law of the Excluded Middle) we conclude that the universe has an Uncaused Cause, which all men call God. It’s also good science — solid a posteriori reasoning.

***

"If you look carefully, the scientific evidence for God is much stronger than the evidence for the Big Bang or for any commonly accepted scientific theory. The evidence employed in the First Cause argument is the fact that change occurs in nature, which is undeniable, and the logical process that follows is recognition of the nature of potentiality and actuality and the impossibility of something existing and not existing in the same way at the same time. From this undeniable evidence and solid logic we infer that a First Cause exists. The a posteriori reasoning behind the scientific evidence for God’s existence is much stronger — much more compelling scientific evidence — than the evidence for any other theory in natural science.

"We on the reality-based side of this debate must not cede science to the atheists. Atkins is right that science can answer some of the biggest questions we can ask, such as “Does God exist?” Atkins’s problem is that he doesn’t like the answer science provides: using the ordinary methods of a posteriori inference essential to the scientific method, scientific evidence and logic clearly demonstrate the existence of God."

Comment: Of Course I use the science of natural theology. The complexity requires a designer. and the complexity and the steady direction of evolution to the final result of the human brain makes the case for design. There is no room for a theory of self-design which would never create the directionality of evolution.

I don’t see how anyone can deny that there must be some kind of first cause. The question is what is its nature?

Scientific evidence and logic do no such thing! This is every bit as unscientific and illogical as the argument that science demonstrates that God does not exist. The only form of consciousness that we know of and can observe is that of material beings. What observable evidence is there that a conscious mind can exist without a source, has always been in existence, is capable of creating universes and living, material organisms? The case for design is indeed strong, but if you believe a conscious designing mind can exist without a source as “first cause”, why should someone else not believe that conscious designing minds can evolve from ever changing materials as “first cause”? Why should eternal, ever-changing, ever-evolving materials be less “scientific” than an eternal, all-powerful, all-knowing, immaterial conscious mind?

My own view is that science cannot possibly answer any of the “biggest questions” simply because science is confined to the study of the material world as we know it, and we have absolutely no way of knowing if the material world as we know it comprises a true and complete account of all reality.

DAVID: Of Course I use the science of natural theology.

Of course there is room for a theory of self-design (whether theistic or atheistic). It would explain the higgledy-piggledy course of evolution, and the drive for survival would explain the increased complexity from bacteria to elephants, whales, eagles and humans. Your own theory, however, has been covered comprehensively on other threads, so please let’s not discuss it here as well.

Yes, design is required. the drive for survival is pure unacceptable Darwinism. Living animals are very wary for day to day survival, but have no foresight or ability to arrange for new modifications to enhance survival. Survival is good or bad luck, per Raup, if you believe in Darwin as he did.

I don’t know why you need to complicate the argument with this analogy, but it fits to a small degree, in so far as you do need designing brains to analyse current conditions (though these are new in the context of evolution) and make the changes required. Of course design requires mentation – hence the concept of the intelligent cell/cell community, which analyses the new conditions and either makes the changes required, or goes extinct. “No crystal ball required, just designing brains as usual.” Extension of the process: new conditions may allow for experiments in new forms of behaviour, leading to innovation. Still “no crystal ball required etc.”. The crystal ball is an image for foresight. No foresight required. Thank you for agreeing with me.

Your house is a poor analogy. The ‘crystal ball image’ is not hocus-pocus, it stands for looking into the future. My theory follows the same pattern that you have outlined: analysis of current conditions (in evolution, this involves changes to the environment), and adaptations for the changes required. Your architect knows from experience of possible future problems (flooding, subsidence etc.) but does not look into the future for unknown possibilities,and organisms don't either. They respond to current conditions. The only role played by the future is the obvious one that the changes are required in the present if the organism is to have a future!

Reality

by David Turell @, Friday, November 08, 2019, 14:36 (354 days ago) @ dhw

DAVID: I think quantum mechanics is the basis of reality.

dhw: …if you agree that a collision between buses and humans is a genuine form of reality, with all its dire consequences, why do you think that “quantum fuzziness”, a wonderful description of the current state of quantum mechanics, is the basis of reality? Secondly, you cannot escape the fact that quanta are material, and yet you believe that the basis of reality is an immaterial God made of “pure energy”, and our consciousness is an immaterial blob of his consciousness. I find this bewildering.

DAVID: Simple: I think there was primordial energy before quanta appeared as God created the universe.

dhw: In which case, you do not think that fuzzy quantum mechanics is the basis of reality.

Wrong: our reality is an invention by God from that primordial energy with quantum mechanics as the first step


DAVID: I think my supposition of an eternal pure energy as the source of everything is a reasonable possibility. we don't know what is on the other side of quantum uncertainty.

dhw: I suspect that George will find it even more reasonable to argue that the source of everything is material, but I eagerly await his own comment. I will stick to the fact that material reality is the only reality we would all agree on (bus smashes into quantum theorist and splatters him all over the road), and since we don’t know what is on the other side of all the things we are uncertain about, the most “reasonable” approach is that of the agnostic, who candidly admits that he doesn’t know and therefore can’t choose between the different theories.

DAVID: The bus is no equivalent to quantum experiments such as late choice. We are not touting multiple worlds or other nonsense.

dhw: I never even mentioned multiple worlds or other nonsense, and I would suggest to you that quantum experiments such as late choice are no equivalent to the solid material reality of the bus. And I would repeat that since, in your own words, “we don’t know what is on the other side of quantum uncertainty”, it is more reasonable to admit that we don’t know than to adopt the fixed beliefs of theists and materialists. But I hasten to add that I respect such beliefs so long as their champions admit that their beliefs demand a leap of faith.

The bus is not quantum mechanics, and is a very poor example of a refutation. Our consciousness plays a role in the strange results.

Reality

by David Turell @, Thursday, November 07, 2019, 00:15 (356 days ago) @ dhw

GEORGE: I agree with most of DHWs comments here (though not having read either the book or the review). Where I differ slightly is in the nature of "objective reality". The evidence from modern quantum science appears to be that on the smallest scales reality becomes rather "fuzzy". So any objectivity can only be of a probabilistic or statistical kind.

dhw: My argument is that we have no way of knowing what is “objective reality”, but that does not mean there is no such thing. Consequently, it is absurd to suggest that the reality we think we know is actually unreal – and that is my quarrel with some quantum theorists, whom I always invite to test their theory by stepping in front of a moving bus.

I think quantum mechanics is the basis of reality. We need to understand it better than we do.
