Do you think we can demonstrate that feelings are not the product of physical events? — Tom Storm
The really hard problem of consciousness is the problem of experience. When we think and perceive, there is a whir of information-processing, but there is also a subjective aspect. As Nagel (1974) has put it, there is something it is like to be a conscious organism. This subjective aspect is experience. When we see, for example, we experience visual sensations: the felt quality of redness, the experience of dark and light, the quality of depth in a visual field. Other experiences go along with perception in different modalities: the sound of a clarinet, the smell of mothballs. Then there are bodily sensations, from pains to orgasms; mental images that are conjured up internally; the felt quality of emotion, and the experience of a stream of conscious thought. What unites all of these states is that there is something it is like to be in them. All of them are states of experience. — David Chalmers, Facing Up to the Problem of Consciousness
Sure we enjoy drinking the beer or whatever, sometimes more sometimes less consciously. Drinking the beer may initiate feelings in the body that we can be more or less aware of. I don't see any reason to think machines have such experiences. The redundant feature is that these feelings are reified as a kind of entity we call qualia, which are over and above the drinking of the beer or whatever. — Janus
I'm not saying that our feelings and creative imagination have no value but that there seems no substantive reason to believe they are not real, physical, neuronal, endocrinal and bodily processes. — 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
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
Everyone I've read who believes physicalism is the answer says we just need to wait until the physicalist answer is figured out. But that's not evidence that physicalism holds the answer. — Patterner

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.

All of Greene's books, of which I've read The Fabric of the Universe, consist of paper and ink. Is that all they are? How does the meaning they convey arise from the combination of ink and paper? — Wayfarer

What said is true, but what you interpreted is not what he meant. The "shapes" on a computer screen are indeed physical, but it's their meta-physical*1 meaning (forms) that might affect you : first intellectually, and then emotionally, after the threat to your belief system registers in the brain, and causes a series of physical responses to combat the metaphysical threat. Wayfarer is not going to attack you physically, by sending bullets over the internet. Instead, he could affect you metaphysically, by causing you to believe that you have been psychically injured (offended).I could say something to you right now which would raise your blood pressue and affect your adrenal glands. And in so doing, nothing physical would have passed between us. — Wayfarer
That's just not true. If you are talking about what you write on the computer, then I would be looking at shapes (letters, words and sentences) on a screen which means the light from the screen enters my eyes and stimulates rods and cones, causing nerve impulses which travel to the brain and cause neuronal activity which in turn may or may not raise my blood pressure and affect my adrenal glands. — 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
Some people --- writers, artists, designers --- will get more riled-up if someone steals their Intellectual Property*1 than some tangible physical property. Again, it's the meaning that matters to them. But lawyers have to be very creative to convince a jury, using materialistic language, that something of value has indeed been stolen. How do you think the (hypothetical ; intangible) creator of a Mind Created World would feel about h/er creatures denying the value of h/er most important creation : the human intellect? :joke:it has nothing to do with anything physical. It is only about the meaning. — Patterner

suppose we found that specific patterns of brain activity in Yo-Yo Ma’s brain reliably correlate with his playing Bach’s Cello Suite No. 1. This finding wouldn’t be surprising, given his years of training and expertise. Although that information would presumably be useful for understanding the effects of musical training and expert performance on the brain, it would tell us very little about music, let alone Bach. On the contrary, you need to understand music, the cello, and Bach to understand the significance of the neural patterns. — Why I am Not a Buddhist, Evan Thompson

'Arises' from what, exactly? What is the nature of the causal relationship? — Wayfarer
If meaning arises purely from physical causation, as described by physical and chemical laws, how to account for the gap between these deterministic processes and the open-ended, adaptive nature of life? Even rudimentary organisms exhibit an agency and intentionality absent in inorganic matter—the ability to heal, reproduce, evolve, and maintain homeostasis. From the moment life begins, biological systems exhibit a kind of semiotic agency that transcends the deterministic causal nexus of physics and chemistry. Life doesn't defy physical laws, but requires principles that can't be reduced to that level of explanation. Recognition of this is one of the drivers behind the emergence of biosemiotics, and of the connection between information and biology, none of which is strictly physicalist, although it falls within the ambit of an evolving naturalism. That's the sense in which biology is evolving beyond physicalism, as physics did with the advent of quantum mechanics. And all the same questions apply to the relatonship of neurobiology and semantics.

I agree. What may be missing from the picture you see is the Interpretation or Understanding of its meaning. Your dog may see the same symbols on the computer screen, but they won't have the same "affect"*1 that they do on you. The effect is physical, but the affect is metaphysical (mental). Your dog may be emotionally affected by images of other dogs on the screen, but words in the English language will have no affect, because they are abstractions of intellectual ideas, not concrete objects.What ↪Wayfarer said is true, but what you interpreted is not what he meant.

I am affected physically by what is said (sound) or what I read (light) and this causes changes in the body and the brain, and those changes are my interpretation of the meaning of what I have heard or seen.
You might not agree with this picture of what is happening, but nothing is missing, except of course complete understanding, which shouldn't be a surprise since we don't completely understand anything. — Janus
Meaning in a brain emerges from systematic Holistic interactions, not linear Reductive operations. A more Holistic term for "arise" would be "emerge"*1. Your description sounds mechanical, but it doesn't answer Chalmers' Hard Question : how does a mechanical process convert physical inputs into mental outputs? In philosophy, to equate mental with physical is a category error. :smile:Arises from interactions within the brain which contains the neural networks trained to process written language, in response to the outputs of those neural networks signaling recognition of linguistic elements in the writing. — wonderer1

Brandolini's law, also known as the bullshit asymmetry principle, is an internet adage coined in 2013 by Alberto Brandolini, an Italian programmer, that emphasizes the effort of debunking misinformation, in comparison to the relative ease of creating it in the first place. The law states:
The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.
