How can you doubt that after saying that "it (consciousness) navigates an abstract, data-compressed geometry generated by our brains' image-processing"?

Because your original point was this: "If we humans were able to swap out our senses for completely different ones, we might discover that a lot of facts and knowledge we had about reality just isn't valid anymore." You did not say: "If we humans were able to shut off our senses, we might discover that a lot of facts and knowledge we had about reality isn't observable anymore." If you had said the second thing, I wouldn't have said "I doubt that", because I'd agree with it. But you haven't.

This idea or proposition is a shift in perspective from a materialistic one which puts the existence of a mind-independent reality as a fundamental axiom, to a perspective that starts with the realization that, as you put it, consciousness navigates an abstract, data-compressed geometry generated by our brains' image-processing.

Not really, because the geometry of the cave is still a mind-independent reality. There's no reason why the consciousness of a human with a functioning headlight couldn't perceive it the same way as the consciousness of a bat with a functioning sonar.

Yes, that is the axiom I was referring to. Few people are willing to admit that this assumption is indeed an assumption. Even fewer are willing to consider that it is neither warranted nor needed to describe the reality we perceive, which is the only kind of reality we need and ought to concern ourselves with.

My argument is that it is more accurate to refer to reality as the species-specific existence we experience. The "common geometry" is part of this experience, but if we state that it is reality, we are ignoring the possibility that it is only potential reality, becoming actual reality only within the context of a species-specific experience.

I needed to think about this point a little longer. Now that I have, I'm wondering if we have a real disagreement about it or if we just use different language for the same thing. So in your opinion, what is the distinction between the following two statements, and what does it matter?
  1. "The geometry of the cave is a reality, but we discover it only within the context of a species-specific experience", and
  2. "The geometry of the cave is a potential reality, but it only becomes an actual reality within the context of a species-specific experience."
In my opinion, it may well be the same statement expressed in different vocabularies. What is the substantive disagreement in your opinion?

Good. Adopt the posture of the child by all means. Philosophical discussion would obviously be futile with a child. Thankyou for making that clear.

It is a necessary assumption to account for the replicability of scientific results. Two different teams mapping the cave independently would arrive at very similar results, +/- their margin of error. How do you explain that otherwise?

There IS a need to concern ourselves with what we don't know or can't perceive. It's called curiosity.

@Thomas,
In my opinion, 1. assumes an existence of reality that is not species specific, but that is somehow more real than species specific reality.
Given that 'reality' is something we experience entirely and completely species specific, assuming that there is anything outside this species specific relationship with it's perceived surroundings is unwarranted. And ascribing this something with the status of absolute reality is rather illogical, it seems to me.

2. states with greater clarity precisely what is meant by 'reality'.

After all, it is through experienced reality we have come up with the idea of absolute reality. 2. recognizes to a greater degree that our perception matters in how we experience reality, and that whatever is outside of that experience simply isn't real to us.

You're welcome. Thank you for making clear that philosophy boils down to clique politics and name-calling for you, and that "child", "naive realist" and so forth are bad names for you.

It is not. The two teams are of the same species, using similar methods to map the cave, and the comparable results are not "absolute reality", but "reality as defined by those who did the mapping".

No. Seeking to understand and describe what we perceive but do not understand is called curiosity.
To invent ideas and claim they are real without any proof or evidence that they are is called delusion.

Funny you'd say something as factually baseless as that...

When I was a teen, i used babysit some kids of my parents' friends. For the money but i also liked it, they were adorable. One boy about 5, one girl about 7... One day at a party, with other kids around and the parents in the background, the 5yr old boy asked me, with a very serious and calm tone: Olivier, why do we all have to die?

I looked at him and at the other kids. They were all waiting for my answer. They figured I was as much a kid as they were... Maybe I would tell them the truth, the simple truth their parents were hiding, like that other thing they hide from children about making babies...

From the tone of the question I could sense no fear. The boy and his sister were not afraid, just sad and curious to know why such a grave injustice should be meted on mankind, and on themselves.

Tears were pressing into my eyes when I answered, as best as I could, something like 'toys get broken after a while, and then they don't work anymore. Our body last much much longer than most toys but in the end, it breaks down too. It can't last forever...

That was a materialist response, which made sense to me, and to them too... but I could have gone with a religious reply or harp on death being philosophically not unproblematic at the conceptual level... For that was a philosophical question.

As a proponent of 1, I agree up to the word "but". Your comparison after the "but" is apples-to-oranges to me. What you call "species-specific reality", I call "perception of reality". I agree that perception of reality is species-specific, but perception relates to reality as maps relate to territories. Comparing the "realness" of perceptions and realities strikes me as a category error, just as comparing the "realness" of maps to the "realness" of their territory. Territories are real. Maps are realistic (or not) in representing territories. But although maps are also real in the trivial sense of being papery things you can hold in your hand, that has nothing to do with the territory and their relation to it. Likewise, reality is real; any species' perception of it may or may not be realistic. But to compare the "realness" of "reality" and "species-specific reality" is simply a category error, a confusion of real with realistic.

Cyracuz wrote:

Maybe in your vocabulary it is. In my vocabulary, reality is whatever is out there. It is not species-specific, although our experience of it, if any, undoubtedly is.

Cyracuz wrote:

"Illogical"? What's the logical contradiction?

Cyracuz wrote:

I disagree with that for two reasons. First, "is meant" by whom? Dictionaries describe clearly what is meant by the term when conventional speakers of English use it; what they mean by it is consistent with my usage and clearly inconsistent with yours. So who is the antecedent of your "is meant by"? And why should we prefer his or her coinage of words over everybody else's? Second, I think statement 2 confuses maps and territories by calling them both "realities". By doing so, it obscures what is meant by "reality" rather than making it more precise.

Cyracuz wrote:

I think that makes a travesty of the English language. In standard English, bacteria were as real in Plato's time as they are today. This is so even though Plato's perception of bacteria was less realistic than ours: he didn't have microscopes; we do. To clarify our languages further, let me ask you this: In your vocabulary, what happened on the 23th of February 1590 at 10 am, when Zacharias Janssen invented the microscope? (I'm making up the date and hour.) Did bacteria spontaneously spring into existence from one hour to the next?

They don't need to use similar methods to arrive at the same map of the cave... Face it, the presence of an objective cave with an objective shape is the only hypothesis able to explain the similarity of measurements by 2 independent teams.

Curiosity is seeking to know the unknown. Do you agree there is such a thing as 'what is unknown'?

How do you call it?

That is precisely the kind of comparison enabled by the belief in absolute reality.
Another comparison might be that perception relates to reality like books relate to stories.
The book itself is not reality, and neither is the reader. But the way they come together in the reading is reality.
Or perhaps perception relates to reality like images on a computer relates to binary code?
Maybe our brains are like computers interpreting this code. In that case the code would not be reality any more than the code for the image of a flower is the actual image.

Quote:

Then our disagreement seems to be a matter of what precisely we each think of as being real. "Whatever is out there" does not disqualify any of the comparisons I made above.

Quote:

As you seem to agree to, any experience is species specific. It is also a requirement for something to be considered real that it is a demonstrable fact.
The contradiction then is that an idea of reality that cannot under any circumstance be demonstrated is understood as fact. It does not contradict intuition,but it contradicts the logic from which these concepts get their meaning. I don't know what you call that kind of fallacy, but it is a fallacy.

Quote:

Could you clarify how my use of the term 'reality' is inconsistent with the dictionary definition?
The dictionary definition relies on our ability to observe and experience that what it says is true. It does not rely on a belief in absolute reality.

Quote:

No. It calls your 'territories' potential reality or informational code, and sentient interaction with it reality.
In other words, I am arguing that reality might include the processing of the code, not just the code itself. There might not be anything but unread code on a universal hard drive somewhere if there were no code processing.

Quote:

There had always been something to make people sick. But when these things were identified and described and named, bacteria became a reality. Before that it was god's will or whatever other explanation that was available.

Yes, of course. But even "the unknown" must have something linking it to the reality we experience for it to be considered potential fact.
The higgs-boson, for instance, and black holes. Both were theorized to exist long before they were observed.
But they weren't accepted as reality until that had occurred. There were strong indications, so strong that most scientists said they were 99% sure, and it was just a matter of time.
And even with that kind of certainty, neither black holes or the higgs fields were considered facts until either demonstrated or observed.

Then there's god. Assumed to exist since forever, and as of yet it hasn't been demonstrated or observed. You speak of curiosity, and yet you resist the idea that 'absolute realty' is as elusive a concept as god, an idea that certainly sparks my curiosity.

What exactly do you mean by "the reality we experience"; why do you not just call it the reality; and if there is a difference between the reality and REALITY...what is it?

Scientists, philosophers and assorted clever dicks are almost incapable of saying "I don't know" so they go red in the face, stamp their foot and pout rather than say it..Wink

No it isn't. I can read Mickey-Mouse comics, and the book and my mind will come together, but that doesn't make talking mice a reality.

Exactly. That's what it takes for us to consider it real. But demonstrating it as a fact isn't what makes it real.

Cyracuz wrote:

According to Merriam-Webster's dictionary, reality is "the true situation that exists; the real situation; something that actually exists or happens; a real event, occurrence, situation, etc." Other dictionaries offer similar definitions. They are inconsistent with your view of reality in that the observer's consciousness doesn't play into them, whereas this consciousness is crucial to your concept of reality.

Before that, people thought it was god's will. But they were wrong. Bacteria had always been the real cause of those illnesses. Does your vocabulary allow for any space where people think something about the reality they live in --- and are wrong?

Don't play games, Cyracuz. Why did you use the expression "the reality we experience."

Since you think that REALITY...IS...the reality we experience...

...why didn't you just write "reality?"

By the way...REALITY is REALITY...

...it IS what IS...without regard to whether humans can "experience" it or not.
