Idealists: What does 'physical' mean to you?

Absolutely fab. May I please use this along with my standard "magic powder" and "pixie dust" jibes. I promise to share too! :)

For sure, though personally I am basically materialist, largely because I like a challenge and because materialism seems to tie the mind down more. With idealism people fly off all over the place. You start discussing with a bunch of idealists and you can pretty much guarantee that within 15 mins everyone is at different ends of the universe. With materialists you can hold better to the subject matter.

Hilarious. Maybe call the cops so Nick won´t keep hanging around your street corner.

The difference between me and RD, as I see it, is that I am actually genuinely interested in the truth, whereas RD is only interested in being a good materialist, rather in the same way a Western religious type may be only interested in being a good Christian.

Thus RD seems to regard anyone who challenges materialism as a troublemaker, not a source of potential new insights. He's looking for faith. I'm looking for truth.

There's this cartoon of a bunch of mathematics scrawled on a blackboard with two sides of an equation linked by a box with the writing inside "...and then a miracle occurs..." I'm the annoying soul who isn't really satisfied with the equation. I want to make the box smaller.

That HypnoPsi's argument appeals to you does not mitigate the fact that it is complete nonsense.

Pixy I'm sure you recognize hyperbole when you see it. I thought the "golden cookie award" might have given it away. ;)


I think he did a good job of injecting some new points into the discussion but, If you read the rest of my response you'd see that I don't agree with him 100%
 
Consciousness comes from living brains similar to the way music comes from instruments. Music isn't matter, but it relies on matter and is not "magic". The fact that people go out of their way not to understand this analogy doesn't make consciousness mystical--nor does it make it parsimonious to posit some supernatural entity or source for it.

If hypno's jabber about parsimony sounds "deep" to you, it's probably because you desperately wish to believe in souls and are searching for some means of keeping yourself from understanding the above paragraph. Brains make consciousness like instruments make music. Alter the instrument and you alter what is produced by the instrument. Destroy the instrument, and all production stops.

We live in a universe in which only two things actually exist - consciousness and information. Yet - and here's the real kicker objects do indeed continue to exist even when we're not looking at them or thinking about them.
...
Well, to my mind, even though both (prima materia versus God) are both valid and testable (in principle if not in practice) theories, the God theory clearly has the edge for the very simple reason that we already know that consciousness and/or mind exists while we have no evidence for any substance of any kind.
You just contradicted yourself.

Is music "substance"? Why do you think consciousness demands a more "metaphysical" explanation than music?
 
Read back the threads, RD, and link me where you agree that it's counter-intuitive. Do it and I will believe you. Both you and Pixy have flat out denied it in recent past posts.

We said it wasn't counter-intuitive for us. I dunno about pixy, but I am an A.I. programmer. I come up with algorithms to perform human cognitive tasks for a living. So of course a computational model of consciousness isn't that farfetched for me.

For me, neither of you demonstrate much intellectual honesty. You don't say it when you're wrong. You don't say it when you don't understand. You just quietly reform your opinions in the background.

Even if you are right about that ... so what? Isn't a reformed opinion an implicit admission of prior error?

Read back the threads, RD. This is tiring. You constantly accuse me of misinterpreting your language. It's your usual back door out.

OK Nick, lets play this game again.

You ask for consistent definition of "I" or "self."

I respond with "the entity typing this sentence."

Refresh my memory -- what was your response to that definition? I remember it being some nonsense along the lines of me not fully understanding what "entity" and "typing" and "sentence" were, because "they are all just processes." Am I incorrect? I mean, is 'the entity typing this sentence' incorrect?
 
I'm the annoying soul who isn't really satisfied with the equation. I want to make the box smaller.

You are the annoying soul who is trying to blur everything into uselessness.

You have made utterly useless arguments, such as an assertion that it is impossible to distinguish between material processes.

You have, among other things, asserted that there is no "self" despite the fact (which we have pointed out to you) that the entire field of computer science relies upon the notion of "self."

It seems to me your true goal is the complete obfuscation of computer and cognitive science via the denial of agreed upon definitions.
 
Without information on what occurs in the brain at these times (where subjects may very well consciously judge that their decision occured at a time earlier than which an EEG analysis determines the readiness potential occured) how can you claim to have a "proven" conclusion?

You have very slim data (all of it reliant upon testimonials from subjects in one way or another) from a very slim and restricted set of circumstances.

There was a more recent study completed in 2008. It appeared in "Nature Neuroscience." I will post a link to the abstract when I get back to the machine with the bookmark.

You are right that one should not reach the conclusion that the traditional ideas of a "conscious decision" are obsolete now. That wasn't my point.

My point was that there are known examples of decisions that an individual would insist were conscious yet are provably not. And this fact leads to the conclusion one cannot fully trust whatever faculty leads a human to claim a decision was consciously made -- because we have instances where that faculty is wrong.

And that, unfortunately for people like plumjam, means personal experience is not a completely reliable authority.
 
Your intuition tells you what evolution has programmed it to tell you.
Intuition is learned as much as it is genetic.

Unless you are telling me that my intuition about, say, algorithm optimisations is encoded in the 17th chromosome?

Severe mental illness aside, you will believe that you are an individual experiencing a world of objects, thoughts and feelings.
No.
 
Can you cite me some research here? Thoughts don't appear to me to be material though I would be happy to be convinced they were!
You haven't bothered to read a single post by anyone, ever, have you?

Because if you had, you would know that the entirety of human history is evidence for this.
 
No, it's not wrong. For thousands of years the debate has been between "mind or matter" (defined as immaterial thought and fundamental substance).

Nobody has ever came up with a third option.
Wrong. Information is one. Computation is another.

What is not an option, and never has been, is mind. If the fundamental nature of reality is "mind" in some sense, then that mind gives rise to matter, and the observable nature of reality remains material.

You cannot explain minds as we experience them by using "mind" as the fundamental existent, because minds are, plain and simple, physical processes. Every bit of evidence ever collected tells us this.

Again, that depends upon what evidence you accept. Though I am certianly not going to say that all NDE's or all mystical experiences (or all described thereof) are "real" I am fully satisfied that there is "truth" somewhere in them there accounts.
Thanks. Now I know where you're coming from.

NDEs and mystical experiences are fully explained by physical processes in the brain. There is exactly zero evidence that anything else is going on.

And don't just dismiss them as anecdotes. Anecdote just means "unwritten" which is not the case with NDE's, etc.,. They are data because they have been collected, collated, and reduced to statistics (data) in terms of the elements each one contains.
Anecdotes reduced to statistics are still worthless.

NDE's etc., provide data - plain and simple.
Data, yes. Evidence supporting your position, no.

No he didn´t. Objects do not equal substance.
Okay, but there is still a problem. What is it that allows objects to continue to exist when we are not thinking about them? It isn't consciousness. There must be another mechanism that preserves the continuity of the world. Let's call it "substance" or "external reality." Now suddenly the God theory loses its edge.

You can try to save it by saying that God thinks about the entire universe while I'm not, and that's what preserves the continuity. But then you need a mechanism for God to refresh my memory of a scene when I come back to it. What does that have to do with consciousness?

I'm not an A.I. programmer as such, but I build complex systems that need to be self-monitoring, which takes me into A.I. territory. So, likewise, a computational model of consciousness has become intuitive for me over the last 20 years or so.
 
That only leaves mind - or "Overmind"; a term I seem to have unwittingly coined.

Cheers,
HypnoPsi

Actually, I think the term "Overmind" got into usage after being used as the name of an alien antagonist in a Blizzard RTS game ;)
 
Hope you don't mind; I'm going to snip some of the questions that were effectively asked multiple times and just give the answer once.

What's wrong with just accepting it as it is - pure, raw, information?
Nothing at all. That's informational idealism.

As I said earlier, it is what it does. It's a small step from saying an electron is defined by its properties to saying that an electron is its properties. That it's all just information.

This does not change anything at all.

It doesn't make NDEs anything but the confused product of a dying brain.
It doesn't make mystical experiences anything but the confused product of an otherwise addled brain.
It doesn't make God real.
It doesn't make consciousness anything but a physical process.

All we've done is ignored the question of substance and accepted that all we can know is behaviours.

Personally, I describe myself as a phenomenologist and amaterialist. I don't see any need to think of the manifest Universe as ideas or material.
The Universe is material. After all, I can take a chunk of it and hit you over the head. Whether there is any deeper reality underlying what we observe is the question.

Materialism says "it is what it does".

Informational idealism says "there is no is, only does".

An electron, to me, would simply be a set of laws.
And that's what I call informational idealism. The critical point here is that the laws do not change in any way. The laws are deduced from observation, and tested by further observation.

Because otherwise it's dualism, and dualism either (a) is inherently inconsistent or (b) postulates an inherently inconsistent universe.

I didn't say it was surprising. The 'kicker' I'm refering to is the question mark over why there is something rather than nothingness?
Grilled cheese sandwiches.

What exactly is this physical/material stuff of which you speak? Please be specific in your answer.
As I've indicated, there are two answers I'm happy to accept.

One is, it is what it does.
The other is, there is no is, only does.

In the one case, matter is what gives rise to the behaviours we observe.
In the other, matter is a description for the behaviours themselves.

But why believe in a material essence in the first place
Because it is parsimonious.

Reality is indisputably material. To assume that it is essentially material as well is the most parsimonious option.

Look, thousands of years ago when the likes of Leucippus and Democritus thought up the theory of some fundamental substance (materialism) or other underlying phenomenal/neumenal objects it did indeed seem like a pretty good idea - to them. (Certainly much better than vitalism and animism, as they saw it.)
Indeed.

But that was thousands of years ago. Why hold onto this theory (sic fantasy)?
Because it works.

There is no substance - physical or otherwise - at all. There is only information.
That's fine too.

The point is, it's exactly the same.

The "so what" is that people are being encouraged to live a fantasy. If science textbooks and teachers were to strongly stress the fact that words like "physical" and "material" were only placeholder terms for information that would be a step in the right direction.
It makes no difference. None.

However, my sense here is one of skeptics/atheists/materialists gaining by keeping people in ignorance. Happily throwing up their hands at the end of the day saying "Oh, well... look... if students take the words "physical" and "material" to mean some substance or other... it's not really our fault".
It makes no difference.

Why not just be honest and call phenomenal reality and phenomenal objects for what they are - phenomenal reality and phenomenal objects?
Because that's complete nonsense.

Objects are real. Reality is real. Your conscious awareness of reality is just a physical process.

What stuff??
All stuff.

It's more accurate.
No. It's exactly the same.

Science has gone through this before with other ideas like the aether.
The luminiferous aether hypothesis makes specifically testable - and as it turns out, wrong - predictions.

Materialism vs. informational idealism makes no difference to science in any way.

Not wrong - just different from how we have previously looked at them. F does still equal MA in terms of the same event occuring. The only difference is that we should not look at M (mass) as being a substance. (For example, in QLM its all just basically braiding.)
QLM? Never mind, not important.

What is important is that F=MA. The law does not change. Physics does not change. Nothing changes.

No. Information is information. "Matter" is a subjective sense about said information.
It's not subjective at all.

At best, it is a placeholder term.
That I can grant you.

At worse it is very misleading in terms of it's historical connotations.
It's only confusing if you are utterly determined to be confused.

And you're forgetting that science is about construction theories rather than standing still. There is no reason why the rest of us should stop asking what underlies reality (and/or what is the most parsimonious theory). Materialism has plateaued out - and evaporated. Playing let's pretend it doesn't matter and just keep on using the terms "physical" and "material" isn't good enough for me. You go ahead and feel free if it suits you.
This displays a complete misapprehension of both science and philosophy.

Science is based on methodological naturalism. Science works. This tells us (though it does not prove) that metaphysical naturalism, and more specifically, scientific natuarlism, is correct.

Metaphysical naturalism says that the Universe behaves as though it is made out of matter.
Scientific naturalism adds that this behaviour is consistent throughout the Universe.

Materialism is a reasonable assumption (but only an assumption) for the underlying nature of reality given this evidence. Informational idealism is likewise reasonable.

God is not.

I would say that's rather simple. A truly self-generating and self-sustaining (i.e. truly uncreated) substance would instantly and forevermore end all ideas of "God" permanently since no candidate for God could be God if something God had not actually created existed (since, surely, God, if it's posited to be anything is posited to be the creator of all.
The ontological argument was worthless when it was first proposed, and is still worthless.

And the same is true in reverse. Something that could show itself as the only genuine Creative force would end notions of anything being self-generating and self-sustaining.
See above.

If you're saying that matter is an "ideal substance" then I agree. (Though, obviously, I still see it as fantasy.
Yahzi's Bat demolishes this claim.

Well, I have one. How exactly can pure information bring about consciousness? Please be specific in your answer since this is surely not something you expect anyone to believe without evidence, is it?
Well, it's clear enough how material processes can bring about consciousness, since this is done by programmers and engineers on a daily basis.

Informational idealism is simply materialism with the idea of "substance" removed. It changes nothing in the observed nature of reality (nor should it, for then it would be false).

So that's how information gives rise to consciousness.

Why do you think consiousness is a process?
Because it is?

Seriously, what do you think it is if not a process?

Parsimony is like a jig-saw puzzle. Theists have a piece of the puzzle for the Universe, for everything in it and for their consciousness.
No; they have an infinite collection of pieces from an imaginary puzzle.

Since the whole point of being parsimonious is to find the missing piece from the parts that are currently there (and solely from the parts that are currently there) theists are quite justified in suggesting it is a "bigger" consciousness that is the missing piece of the puzzle.
No. This is never justifiable in terms of parsimony.

God is a short word. It is not a parsimonious concept. Indeed, it is antiparsimonious.

Materialism in the traditional sense of the word does not fare so well at all. They have two missing pieces having to infer that some substance exists and that it is self-generating and self-perpetuating without purpose, will or creative impulse Materialists have to multiply unknowns
Again, you have it backwards.

There is no unknown here. We know the material Universe exists. Materialsm simply does not assume that there is something else that exists.

What an absolute mess your last statement is. Being parsimonious with this question is about taking reality as it is now (Universe and us consious beings in it). It's not about asking what happens next/first after God is there.
Sorry, wrong again. God is an infinite set of assumptions; it allows for anything, and therefore explains nothing.


In otherwords your answer is to just avoid the question. Just call "what is" reality
Well, duh.

That's the definition of the term.

and just say it causes consciousness.
No. We observe that consicousness is a material process, and we have gone a long way to explaining the details of that process.

How does this answer the question about how reality got there exactly?
What do you mean, "how reality got there"?

Reality is reality. It is what is. It's all that is. There is no understanding of how it got there, because if we could do so, we would merely be extending our definition of reality.

How did God get there? Oh, he's self-causing? So reality can't be self-causing, but God can be? And at the same time, God isn't part of reality? Surely that means he doesn't exist?
 
Human consciousness is a very specific thing that we know about. Idealists love to extend that limited domain to include God, God's creative impulse, God's maintenance of reality, the partitioning of the Supermind into individual minds, communication between minds, etc., yet insist that all this baroque mechanism is just an obvious extension to the known individual consciousness. It may be true, but it is certainly a leap from individual consciousness, and it certainly isn't simpler than physicalism.

I'm willing to entertain the idea that consciousness is fundamental, but the rest of that stuff is baggage that doesn't come for free.

Is music "substance"? Why do you think consciousness demands a more "metaphysical" explanation than music?

We have a pretty good grasp of where our conscious experience takes place, namely the brain. The problem is we don't really know, ontologically, what it is. What is it that makes the mass of material in the brain seem to feel, experience, and be aware? What IS being aware and why does the matter of the brain seem to experience while other matter does not? What property, or physical principle allows or causes sensate experience?

The fact is

NO

ONE

KNOWS


Period.

That is the mystery and the cause of so much metaphysical speculation and contention. Okay, we've narrowed down the problem: the brain generates consciousness. Great, wonderful. We're still left with the same profound mystery.
