So my comment got quoted. Neat. I'd like to respond to:

> My response: who said anything about metaphysical?

Well, the original author did. The entire article is, at its core, an argument for dualism. Dualism is a metaphysical theory.

As for the accusation that I intended to imply that consciousness was a solved problem, all I can say is "What?" Seriously, how did you get that from what I said?

The problem with the article, and the reason that people responded negatively (although, I think, for the most part thoughtfully), is not that everybody thinks the problem of consciousness is easy, or that it has been solved. It's that the arguments presented were weak and not particularly interesting or novel.

I agree that discussion on HN should be thoughtful and polite. But I don't think that means we should be constantly patting each other on the back and blowing up each other's egos.

I also don't really think the quote mining here was helpful. Here's the comment that was quoted simply as "Not a useful concept": https://news.ycombinator.com/item?id=6195854

Huh, it actually looks like that comment went on to bring up the concept of zombies, and linked to further reading. I guess quoting that part of the comment wouldn't have supported your indignant outrage though.

Finally, the position that consciousness is not a useful concept is an important part of this discussion. How can we even have a meaningful conversation about consciousness without first addressing whether what we're talking about is real?

> I respectfully submit that this attitude should be considered harmful, for several reasons, not the least of which is that it stifles intellectual curiosity into a subject that is still an open book

Indeed. It is quite discerning to see smart people fighting against what they believe to be anti-intellectualism with a fair share of anti-intellectualism of their own. I believe it might have more to do with a lack of exposure to varied subjects rather than a definite lack of intellectual curiosity in general however. Because many hackers are quite intellectually curious in their own domain, yet can still be susceptible to being as cynical and myopic as religious fundamentalists in other areas for some reason. The quality of thinking critically doesn't always seem to transcend domains, so I'm guessing it's a side-effect of living in a filtered environment beyond some developmental milestone of a person's curiosity. The string of comments in this other recent thread showcases this type of odd adherence to lack of understanding quite nicely: https://news.ycombinator.com/item?id=6194276

It really is odd how when philosophy is explicitly brought up, it is generally labeled as a useless endeavor, yet in most other discussions you see philosophical questions being raised all the time with the intention of using them as 'appeals to ambiguousness', when (as you mentioned) most of these questions have already been asked and thoroughly answered by philosophers ages ago. Not that there's anything wrong in not knowing about this, but clearly there's an interest to know these types of answers that arises organically, which makes the dismissal of philosophy an ultimately misguided exercise in cognitive dissonance. Throw in all the (literally ancient) logical fallacies you see being thrown around amongst smart, well-educated people, and it just makes the whole situation even more confusing.

While I admittedly haven't read deeply enough into the psychology behind the Meyer-Briggs personality types, they do define and elaborate on types of people that could logically lead to these kinds of odd views. The easiest example is of the classic INTP vs INTJ types, both of which are strikingly similar, yet supposedly differ in one general crucial area. INTP's take all the input they can about the world and evolve their framework of understanding around it, while INTJ's supposedly form their elaborate framework of understanding first, then explore their inputs that correspond to it. I'm only somewhat partial to this explanation because I line up as a perfect INTP on all counts, but it honestly might as well be astrology at this point for all I know. Still a fun thought experiment though.

EDIT: I realize that most on HN like speaking in more concrete terms, such as about the neurological basis for the notions of 'consciousness' and all that, however abstract argumentation and analysis does have use when talking about the act of argumentation itself. So I hope those who downvoted me at least provide an explanation within that context, because I am admittedly curious about what other perspectives there are on this matter.

it's so exciting to me that this community has some interest in consciousness. my background is 'hacker', but looking forward, I think consciousness is highly relevant (soon, we really will be able to hack our own brains, and when that happens, I think we'll care a lot about consciousness theory).

anyway, I've written some blog posts with some thoughts on this topic that I'll throw into the mix:

I upvoted the original article not necessarily because I thought it was particularly well-written, but because I looked forward to seeing what the HN comments about the article would say. Nevertheless, I left to go somewhere before I had a chance to peruse them. I think in a conversation about consciousness, it's very important to define exactly what it is you're talking about. I'm not a neuroscientist, but I get the…

Neuroscience hasn't been able to produce a single theory on the origin of consciousness, unless one accepts "it emerges from neural activity" as an explanation. Consciousness appears to be the ultimate mystery. There is something very fundamental about it that we don't understand at all. This makes a lot of people uncomfortable, especially the type of people that would like to turn Science into a religion. We just do…

And what is wrong with 'it emerges from neural activity'?

really, it is quite an adequate solution for a species with our current level of philosophical and scientific understanding.

That doesn't mean it is right, and doesn't discount potentially other options such as something that, despite my own strong scientific background, I have a fondness for through buddhism and meditation - and which is mentioned in the original article - that there is just one consciousness we all share in.

despite my fondness for this, the idea that consciousness is an emergent property of a complex neural network is supported by the evidence that shows that damage to the brain will impair an entity's level of consciousness.

Therefore, the idea that consciousness in LIFE doesn't require the brain, or vice versa, is simply mysticism and denying the truth that we all experience

I agree with you that consciousness is quite a mystery, but in terms of the ultimate mystery I feel very strongly that the question of life, consciousness and why there is something instead of nothing is a question that goes together and that they are all intricately linked

I tend to be dismissive of the philosophical conversation. I think what will resolve the question is scientific (biological) study. Maybe math/cs theorists (AI) will get there first. But I am almost certain that no philosophical conversation we can have will give me an insight about our cognition.

Consciousness is a mystery only to those that cannot define what it is. What is the origin of awareness itself? It is the very activities one is aware of. The activities produce energy which we call consciousness. The dimension that the consciousness can see is determined by the quality of the very activities. Consciousness is thus not solely generated by neurological activities. Before denying this because of your f…

I'll be aware even if you remove all activities and all senses from me. For some time, anyway - then my mind will likely wander.

One of the things we can be aware of is our own thoughts. If you count that as another "sense", is your statement still true? (Any neuroscientists out there: is it gibberish to consider awareness of your own thinking as a type of sensory input?)

I didn't say we will never understand it, although it is certainly a possibility. One might argue that Godel's incompleteness theorems suggest a reality where some things are unknowable.

I appreciate your point, but I think invoking Gödel's incompletness theorems in this context is taking them far out of their scope.

I guess that depends on what you believe Mathematics to be. Is it a representation of reality itself (maybe the ultimate reality) or is it just a human construct? I don't know.

It's perfectly reasonable to define consciousness as "that which emerges from neural activity" if your model is able to describe that emergent behavior.[0] This is not the same as describing what it "feels like" from the inside. From your comment, I infer that you are rejecting the explanatory powers of neuroscience because you are expecting it to speak to the "feels like" question. [0] http://lesswrong.com/lw/iv/the…

I disagree, it is only possible at the moment to define _intelligence_ as "that which emerges from neural activity". There is not evidence whatsoever that consciousness emerges from neural activity. This is just a type of religious dogma in disguise. Think about it. Thanks for the link.

None? Ever? Consciousness could just be a free floating quantum mechanical genie attached to my back?

Hogcock.

We are only brains. If your brain gets squished, you don't really care because you'll cease to exist in this light cone.

I am aware of this line of reasoning, but it contains a subtle problem: there is no way to measure consciousness. We assume a correlation between consciousness and human-like intelligent behaviour. We assume that we are unconscious when in deep sleep, for example, but we have no way of knowing for sure. It could just be that we are not recording any memories for later reference. Long story short, no, there is no scientific evidence whatsoever that damage to brain will impair an entity's level of consciousness -- only of intelligent behaviour.

It turns out that it is precisely the claim that consciousness emerges from the brain -- given our present state of knowledge -- that is mysticism. The only possible scientific position here is to say "I don't know".
