How about answering a couple? :grin:↪Patterner OK. I have no more questions for you. — Janus
You believe it could just on account of the fact that it seems to be inexplicable? My point being, it supports my position more than yours. What supports your position?You don't believe it could just on account of the fact that it seems to be inexplicable? — Janus
I have considered the possibility. Can you give me any specific thoughts along these lines?Have you considered the possibility that it is not mind and matter itself which are incompatible, but just our conceptions of mind and matter which seem incompatible, — Janus
Ah. Ok. Can you give me another example of something that can't be explained in terms of physics that is not non-physical?No, it says that the inability to explain something in terms of physics does not entail that the thing to be explained is non-physical. — Janus
You believe it could just on account of the fact that it seems to be inexplicable?You don't believe it could just on account of the fact that it seems to be inexplicable? — Janus
I have considered the possibility. Can you give me any specific thoughts along these lines?Have you considered the possibility that it is not mind and matter itself which are incompatible, but just our conceptions of mind and matter which seem incompatible, — Janus
That is correct.You don't think consciousness could evolve in a merely physical world? — Janus
I was taking about proto-consciousness when I said it's not a theory because it's not testable.As you acknowledge there is no way to test the idea that they are not compatible anyway. — Janus
I just said:Even if you could somehow confirm that mind could not possibly have evolved from physical matter, what difference would that knowledge make to your life as lived? — Janus
Lal: I watch them, and I can do the things they do. But I will never feel the emotions. I’ll never know love.
Data: It is a limitation we must learn to accept, Lal.
Lal: Then why do you still try to emulate humans. What purpose does it serve, except to remind you that you are incomplete?
Data: I have asked myself that, many times, as I have struggled to be more human. Until I realized it is the struggle itself that is most important. We must strive to be more than we are, Lal. It does not matter that we will never reach our ultimate goal. The effort yields its own rewards.
Data: What is the definition of life?
Crusher: That is a BIG question. Why do you ask?
Data: I am searching for a definition that will allow me to test an hypotheses.
Crusher: Well, the broadest scientific definition might be that life is what enables plants and animals to consume food, derive energy from it, grow, adapt themselves to their surrounding, and reproduce.
Data: And you suggest that anything that exhibits these characteristics is considered alive.
Crusher: In general, yes.
Data: What about fire?
Crusher: Fire?
Data: Yes. It consumes fuel to produce energy. It grows. It creates offspring. By your definition, is it alive?
Crusher: Fire is a chemical reaction. You could use the same argument for growing crystals. But, obviously, we don't consider them alive.
Data: And what about me? I do not grow. I do not reprodue. Yet I am considered to be alive.
Crusher: That's true. But you are unique.
Data: Hm. I wonder if that is so.
Crusher: Data, if I may ask, what exactly are you getting at?
Data: I am curious as to what transpired between the moment when I was nothing more than an assemblage of parts in Dr. Sung's laboratory and the next moment, when I became alive. What is it that endowed me with life?
Crusher: I remember Wesley asking me a similar question when he was little. And I tried desperately to give him an answer. But everything I said sounded inadequate. Then I realized that scientists and philosophers have been grappling with that question for centuries without coming to any conclusion.
Data: Are you saying the question cannot be answered?
Crusher: No. I think I'm saying that we struggle all our lives to answer it. That it's the struggle that is important. That's what helps us to define our place in the universe.
The meaning and purpose of a problem seem to lie not in its solution but in our working at it incessantly. — Jung
I don't think I understand you. It looks to me like this says the inability to explain it in physical terms is not important to the question of whether or not it can be explained in physical terms.To me the lack of explainability of experience in physical terms is not a central criterion in deciding whether experience and consciousness of that experience is just a manifestation of physical processes . — Janus
I don't imagine the mental is completely independent of the physical. I don't think we can remove mass or charge from particles, and I don't think we can remove proto-consciousness from them, either.We can imagine the logical possibility that the mental is somehow completely independent, but that is just a logical possibility we seem to have no evidence to believe in. — Janus
Everything in the universe is natural. If there is anything in the universe that is non-physical, invisible, and unmeasurable in quantifiable ways, it is still natural.As to the natural vs. the supernatural/transcendental:
If nature consists of that which is visible and measurable in quantifiable ways — javra
Someone on another site has this sig:what difference do you think it would make to how we live our lives? — Janus
Yes, very interesting things will be happening in there near future, I'm sure! :grin:There are competing approaches to naturalism, and the underlying assumptions guiding what we now call the physical sciences don’t remain static. I assume that within a generation or two physics, which has already in the past 125 years substantially altered its concepts of the physical, will come closer to where the biological and embodied cognitive sciences have arrived on this issue. — Joshs
Nothing about the physical properties and laws of physics suggests subjective experience. That's from an expert in the field of physical properties and laws of physics. But I realize that's very broad, and, obvious as it is to me, I understand why you don't see it. We need to observe something, something small and specific, that cannot be explained completely by physical properties and laws of physics. Something that would be explained if consciousness is causal. If I'm right about consciousness, we'll see such a thing one day. If I'm wrong, we won't. If we do, more people will start thinking in ways that could help solve the puzzle.How do you imagine we might go about finding out whether consciousness is non-physical or not? Do you believe there is some fact of the matter we might one day discover? — Janus
Consciousness is a natural thing. Anything in the universe is natural. The problem is the belief that there cannot be any aspect of the universe that is not in the purview of our physical sciences. As Nagel says in Mind and Cosmos:One way of formulating the hard problem is to ask: if we had a complete, canonical, objective, physicalist account of the natural world, including all the physical facts of the brain and the organism, would it conceptually or logically entail the subjective facts of consciousness? If this account would not entail these facts, then consciousness must be an additional, non-natural property of the world.
How have we concluded that we have so great a grasp of things that we can rule out any possibility that something exists outside of that understanding? The last sentence should be:...intellectual humility requires that we resist the temptation to assume that tools of the kind we now have are in principle sufficient to understand the universe as a whole. — Thomas Nagel
I don't see any suggestions of physical characteristics of consciousness in your quote. I'm not suggesting there is a spacial element. Consciousness is not an object. But we can discuss physical properties of other processes, and see how they come about due to the physical properties of particles. Electron shells explain redox reactions, which are a vital part of metabolism. What can we say about consciousness?Whatever the true nature of what we call the physical is, my point is that there has never been any suggestion that consciousness has any of its characteristics.
— Patterner
Sure there has. You just have to read phenomenology. — Joshs
Whatever the true nature of what we call the physical is, my point is that there has never been any suggestion that consciousness has any of its characteristics.You can only measure dimensions and weight of something which is presumed to remain qualitatively the same over the course of the quantitative measuring and weighing. Any calculation of differences in degree presupposes no difference in kind during the process. Otherwise one is dealing with a new thing and has to start over again. The world doesn’t consist of objects with attributes and properties which remain qualitatively the same from one moment to the next. We invented the concept of object as a qualitatively self-same thing so that we could then proceed to perform calculative measurements. Obviously, this works out well for us, but it doesn’t mean that ‘physical’ objects exist out there in the world rather than in the abstractions that we perform on the continually changing data we actually experience in our interactions with the world. — Joshs
Calling the view you disagree with 'naive "folk" understanding' and 'vague intuition' is not arguing against that attitude. It literally is that attitude.What I'm arguing against is the idea that the truth of idealism is obvious and that physicalism is inconsistent or incoherent. Such facile attempts to dismiss opponent's views and the lack of ability to recognize that others can be totally familiar with the same arguments as you are and yet disagree about what they demonstrate, and the assumption that the if they disagree the other must not understand the arguments, that goes with that attitude is what I continually argue against. — Janus
I have to try to find a way to word this...If numbers didn't exist, then you couldn't be writing about them, so they must exist somewhere.
— RussellA
,
So, then, if the first even prime greater than 100 didn't exist I couldn't be writing about it? — Art48
I can stumble upon something I've never seen before, that doesn't resemble anything I've seen before, and whose purpose or function I can't guess. But I can still measure its dimensions and weigh it.Physical properties combine in many ways, but the results are always physical. We can measure the size of physical objects in three physical dimensions. We can measure mass, weight, volume. We can measure hardness
— Patterner
Are such properties inherent in objects or are they the products of historically formed ways of organizing our relation to the world? Heidegger has argued that we never just see a hammer with its properties and attributes. We understand what a hammer is primordially in what we use it for and how we use it, and in terms of the larger associated context of relevance. The hammer as a static thing with properties is derived from our prior association with it as something we use for a purpose. — Joshs
No matter how anyone views these matters, people were measuring and altering stone and wood to make buildings and bridges long before Galileo.Husserl showed how the empirical notion of object that you’re describing emerged in the era of modern sciences with Galileo. The Egyptians and Greeks first developed the concept of a pure ideal geometric form (perfect triangle, circle, square, etc) as the modification of actual interactions with real , imperfect shapes in nature. Armed with such pure mathematical idealizations as the straight line and perfect circle, it occurred to Galileo that the messy empirical world could be approach using these ideal geometries as a model. Now everything we observe in the actual world could be treated as an approximation of a geometrically describable body. — Joshs
I've read this a few times. I'll keep trying. I just don't see how this changes the fact that physical things are measurable in various ways, but consciousness is not. In what physical terms can we discuss consciousness? What is its speed? How much does it weigh? What are it's physical dimensions? Does it have mass or charge? We can say an awful lot about the physical world with our physical sciences, but our physical sciences can't say anything about consciousness.The notions of scientific accuracy and calculative measurement were made possible by thinking of actual things as imperfect versions of pure genetic bodies. The point Im making is that the physicalism you’re describing (self-identical things with mathematically describable properties and attributes) is not a product of the world as it supposedly is in itself. It is a human invention that depends on ignoring the contribution of subjective practical use and relevance to our perception of the world.
Once we recognize this it is no longer necessary to posit a distinction between an outer world of mathematically measurable things and an inner world of subjective consciousness. And the subject here is not to be understood according to traditional idealism and an internal realm The subject is just as much produced though pragmatic interaction in an environment as the objects of the world it interacts with. — Joshs
I think we should use the word "exist." Perhaps there are types of existence other than physical.Fine. Let's not use the word "exist" — Art48
I wouldn't be so dismissive of people like Chalmers and Nagel. Their positions are far from naive, and are the result of far more than intuition. They have spent countless hours, I suspect at least as many as anyone here, studying the available material on consciousness, trying to come up with theories that fit all the data, and organizing their thoughts writing books about it all.As to the question of the nature of consciousness—we have the scientific studies on one hand and the naive "folk" understanding on the other. As to which to rely on, I will choose the former because I don't think intuition is an especially reliable guide to understanding the nature of things. — Janus
I can't imagine you mean this the way I'm taking it. But I don't know how else to take it, so I'll respond to it that way.Philosophy is defined as love of wisdom. Is it wise to simply accumulate knowledge for its own sake? That almost sounds like accumulating money for its own sake. What is the point of knowledge you cannot use? — Janus
Neural activity is electrical and chemical signals moving along the neurons. That is consciousness? Photon hits retina, rhodopsin changes shape, concentration of ions changes, signal is sent along optic nerve, (skipping a thousand other steps), signal arrives in specific area of the brain. That is a description of my subjective experience of red? That, presumably added to other signals hitting the brain, is a description of my brain's awareness of itself?↪Patterner What you say is not true. We can measure neural activity. Of course, you will say that isn't consciousness, but that is just an assumption—assuming what is to be proved. — Janus
Energy is particles in motion. We know which particles move in which medium. We can measure how fast they move. It's all physical.Or think of energy itself—it can only be measured in terms of its effects. If it cannot be directly observed and measured, will you say it is non-physical? — Janus
It all reduces to physics. We can't follow every particle of air. But we know what they are all doing statistically, and can think of the total in terms of the laws of thermodynamics. But the laws of thermodynamics do not exist exactly as they are for any reason other than the way particles Interact.I agree if by science you mean physics. — Janus
It's ironic that you think consciousness is entirely physical, but would like it to be otherwise in the hopes of an afterlife, while I think consciousness has a non-physical component, but don't want an afterlife. But, of course, you're right. What will be will be.Just as a matter of interest do you care whether consciousness is physical or not? Personally, I'd rather it wasn't physical because then there might be some hope that this life is not all we get. I've made my peace with the idea that this life is most probably all we get, but whatever the case is, I don't think it matters what I think about it. What will be will be. — Janus
You ask this in a philosophy forum?? :grin: Knowledge for knowledge's sake is reason enough for most anything, imo. But the true nature of our Selves, and the explanation for how various chunks of matter can subjectively experience, be aware that they are subjectively experiencing, and be aware that they are aware that they are subjectively experiencing?? That's freakin' fascinating beyond anything else!Beyond those kinds of concerns do you think the answer to whether consciousness is physical or not could matter for any other reason? — Janus
It's not about intuition. It's a lack of physical characteristics. Physical properties combine in many ways, but the results are always physical. We can measure the size of physical objects in three physical dimensions. We can measure mass, weight, volume. We can measure hardness.I get that our experience doesn't intuitively seem to be physical. — Janus
Heh. I hadn't thought of that. :up:too genteel to resort to such underhanded tactics. Ironically, non-physical verbal attacks on odious beliefs are often used by the Physicalist trolls on this forum to counter-attack those who have offended their mentally-constructed non-ideal worldview. :smile: — Gnomon
There is obviously something wrong.↪Patterner Don't you see something wrong with this? — Wayfarer
Indeed! :grin: One of my favorite sci-fi books is Neverness, by David Zindell. In it is a quote attributed to Lyall Watson (I don't know where it is in Watson's writings. Anyway:I find it enjoyably ironic that it might be the case that we lack cognitive ability to determine why we have cognitive abilities. — Tom Storm
If the brain were so simple we could understand it, we would be so simple we couldn't. — Lyall Watson
I imagine so. But also to people like me.Consciousness is surely the subjective experience of physical things. But the physical things don't hint at the subjective experience. Something is happening in addition to the physical things.
— Patterner
This frame probably has special appeal to those who are idealists or religiously inclined. — Tom Storm
A good absorber is a good radiator. And the physical properties of matter that allow iron to become magnetized also make iron subject to magnetism. If there is a non-physical property of matter, right there with the physical properties like mass and charge, that explains the emergence of consciousness, something physical properties don't seem remotely suited for, then it doesn't seem unreasonable to me to think that that property could also make matter subject to consciousness.In fact it is on account of their physicality that they can be causally efficacious. Otherwise we would be looking at dualism which comes with the interaction problem. — Janus
I believe it is self-evident, similar to the way it is self-evident that cheese is not the product of a spinning wheel. As absurd as that example is, I believe the consciousness example is even moreso. At least spinning wheels and cheese are both physical things.↪Patterner Interesting. Do you think we can demonstrate that feelings are not the product of physical events? — Tom Storm
While consciousness is the subjective experience of physical things and events, there is no hint of the physical about it. Let's say very intellectually and technologically advanced beings from another galaxy, who are made of very a different mixture of elements than we are made of, found one of us, and could study us completely at any level, even down to watching every individual particle in us. What is there about the many physical structures and processes that would would suggest to them that we are conscious? Why would they think we are more than robots? Consciousness is surely the subjective experience of physical things. But the physical things don't hint at the subjective experience. Something is happening in addition to the physical things.And within that mathematical description, affirmed by decades of data from particle colliders and powerful telescopes, there is nothing that even hints at the inner experiences those particles somehow generate. How can a collection of mindless, thoughtless, emotionless particles come together and yield inner sensations of color or sound, of elation or wonder, of confusion or surprise? Particles can have mass, electric charge, and a handful of other similar features (nuclear charges, which are more exotic versions of electric charge), but all these qualities seem completely disconnected from anything remotely like subjective experience. How then does a whirl of particles inside a head—which is all that a brain is—create impressions, sensations, and feelings? — Greene
Surely not. We wouldn't have all these threads about the same thing for years and decades of it was any. :grin:I don't believe there is any determinable fact of the matter about all this. — Janus
Aren't you saying the equivalent of, "I don't think comets make any difference, as long as they don't crash into us and negatively impact significant issues"? If we are just the sum of uncountable physical events, then no feelings or beliefs that result from that sum make us any more able to not negatively impact anything than a comet is. Some of us will end up with the feelings and beliefs that don't negatively impact things. But those that end up with the negatively impacting feelings and beliefs are just comets caught in the gravity well. No?In response to your question about people being emotionally affected by things that are said to them or by things they believe; I don't deny any of that—I just think it is all physical processes. So, I'm not understanding your puzzlement. — Janus
You don't merely think our experience of qualia is redundant? You question that we have these experiences? You don't experience redmess, an additional experience to what an electric eye detects? You don't experience sweetness, an additional experience to what ... uh ... an electric tongue detects?What effects do you think our (purported) experience of qualia... — Janus
I thought I was following you, even if disagreeing, until this paragraph. What impact does that thinking have over and above the effects of the neuronal and bodily processes which seem almost unquestionably to give rise to it? If that's all there is, then how can it have any impact? I see you responding to Wayfarer, saying his (his?) ability to say something to you which would raise your blood pressue and affect your adrenal glands amounts to physical interactions. What if he does, indeed, raise your BP, affect your adrenal glands, and whatever other things. In that state, you might, say, react violently when someone you love does or says something you don't like a few minutes later? Is it not just the physical interactions taking place, having nothing to do with your experience of the sum of all those interactions? What does "as long as" mean in this context?All that said, I don't think it really makes any difference if people want to have faith in something transcendent if that is what they need and as long as that thinking doesn't negatively impact significant issues in this life on account of them being thought to be of lesser importance. — Janus
Indeed. And I'm sure there will be numerous more threads about it.Discussion of qualia and the nature and significance of subjectivity are subjects for the numerous threads on David Chalmers and the 'hard problem'. — Wayfarer
This is my point. It is something with its own ontology above and beyond the physical process of an experience. It is our experience of hearing an A major chord, whereas a machine only detects vibrations of 440, 553.365, and 659.255 Hz.I think 'qualia' in its subjective sense as opposed to its 'sense data' sense is a kind of reification, and maybe the latter is too.
— Janus
I always thought that was the whole point, if qualia does not refer to something with its own ontology above and beyond the physical process of an experience there's really no use to the word at all. — goremand
Necessary or not, it is a feeling about drinking it that the machine or very distracted person does not have. Isn't that the point? How can something I have that they do not be a redundant feature? It seems to me this is what consciousness is all about. Would you give it up?You can think of it like that, but really your experience of it is nothing over and above your drinking of it, except as an (unnecessary) idea. — Janus
I haven't been reading nearly all of this thread, so I don't know if you're speaking from a stance other than what I get reading it in a vacuum. But if I'm understanding, them I disagree. We can pour beer into the gullet of a machine that can detect all of the properties that give it its taste, fizziness, and coldness, and give us a printout of those qualities that far exceeds our own ability to analyze it. But that machine will not experience the beer. You can drink it while engaged in an engrossing, or heated, discussion, and not experience it. I hate beer, and naked women all around me would not sufficiently distract me from the unpleasant experience of it.It seems redundant to say we experience the quality of beer, for example, rather than just saying we drink the beer. Sure, the beer has a taste, but that is not separate from its fizziness and its coldness, and they are all just a part of drinking it. — Janus
Everyone please bear with me. As with many things at TPF, I've never heard of this.The Nihilsum would be a concept that exists(or of existence) between the categories of something and nothing by being neither fully one nor the other but instead exists as a paradox that resists clear categorization. — mlles
How is that determined?The one that gets the closest to the truth? — Questioner
Since this thread is intended to discuss common ground between the thoughts of humans and other species, perhaps a new thread, discussing differences, in order to better understand human thought?Humans have a lot of beliefs that no other species has, and we wouldn't without language. That seems like a significant difference to me.
— Patterner
This is the direction this discussion needs to take. — creativesoul
