I know the video very well, he didn't say consciousness was emergent, he just said radical emergence was real. I was very intrigued by this part because it seemed to me that after RLK argued that water wasn't radical emergence, Chomsky didn't defend his view but rather he ran away abruptly using the movement analogy. I think it's a soft spot for Chomsky, it seemed that way for me. — Eugen
Radical emergence is the idea that a new property arises which was not evident in its constituent parts. Some people like to say that since we understand the theory in which molecules turn into liquids, then it isn't radical emergence.
Chomsky can follow the theory and understands it, but doesn't see how particles could lead to liquidity. In a similar, if not significantly more complicated manner, a physicist can understand quantum entanglement, but the phenomenon doesn't make sense.
I know you asked, but it's not entirely possible to do away with intuitions. If we could see how particles combined in a certain way could lead to liquidity, then we'd understand the theory and the phenomenon. It's the phenomenon which is puzzling, not the theory.
So mind is strongly emergent, but it is lower than the brain, the reason being that we discover brains through consciousness. Am I right? — Eugen
That was a very poor explanation on my part, happens when I get carried away. What I should have said is that "saying consciousness is reducible to brains... doesn't say much in our current state of knowledge", instead of saying "doesn't make any sense". Thanks for pointing it out and letting me clarify.
We know that consciousness arises in specific configurations of matter, but not in our pinkies or noses. It's in our brains. We lose a limb; we still think rather well. We lose our heads, we don't think much, etc.
In our current state of understanding, if we say that consciousness is simply brain activity, then we are leaving out almost everything we value about consciousness, including emotions, colors, music, reflection, etc. Our studies of the brain say very, very little about these phenomena so far.
Chomsky is following Russell's "Three grades of certainty", in which Chomsky seems to agree with Russell, that what we are most confident about are out own conscious experience, following that we are confident about what other people say about their own conscious experience - if they're being honest. Following that we are confident about our theories about the world.
It's in this sense that, as Russell points out, when a neuroscientist is looking at a patient's brain, they are actually having an experience of looking at another person's brain, it's not as if the scientist can get out of his body to study a patient's brain, in a "view from nowhere".
A brain, in this respect, is a construction we postulate to make sense of our anatomy. It doesn't mean brain aren't real or that they're "only in our minds", but that, neuroscience is part of our capacity for formulating a science.
That would be more accurate. But there's a lot to add as well.
1. He doesn't care much about the logical arguments in the debate between those who claim consciousness is fundamental and those who don't because he believes science (and not logic) should answer this question. When science tells us what are the properties of what we call matter, then we will have the answer. — Eugen
I'm not clear on what you have in mind here. In the video, he was interpreting what Galen Strawson's view are, and he takes it that Strawson argues that if we want to find out what a mind is, you need to find out more about the nature of the world, because the mind is a part of the world.
He doesn't believe consciousness is fundamental, as opposed to Strawson, he sees no good evidence for panpsychism. The arguments for it are interesting, but not persuasive to him.
2. He has the intuition that there is nothing in the current way of doing science that would ever give us a fully satisfactory answer.
Therefore, it seems we're stuck with a mystery. — Eugen
That's more or less accurate. I think he'd say that we currently have no theory of consciousness, but we could have one, one day. But even if we do, it wouldn't do away with the issue of the misleadingly called "hard problem", because as Locke pointed out, we don't understand how matter could lead to consciousness, even if we are confident that that's what consciousness is, matter specifically arranged.
V. You didn't answer my initial question, or I simply missed your answer. So...
Does Chomsky believe consciousness is one of the three (fundamental, weakly, strongly emergent), or he believes there are many other options that our logic cannot comprehend? — Eugen
As for this question, I don't think he distinguishes much between these views. Radical emergence has become a problem recently in philosophy, these new properties, of liquidity or heat just arose from the phenomena, they're emergent. But if you call it strong or weak is mostly terminological.
As I interpret him, if pushed, he'd probably say that he takes emergence to be "radical" or "brute", in that new properties constantly arise from parts which seem to lack the new property in isolation. He'd also say that calling it "radical" would likely be misleading, because it's normal science.
We do the best we can to construct theories from these new properties.
I know that was long, and I probably left something out, but I needed to clarify a badly phrased reply. Obviously if you want more clarifications or have doubts, let me know, I'll try and help.
