You've hit on the root of the debate, but you might have missed it. The debate is to define the meaning of consciousness. We've got a general problem of not knowing what consciousness is, if it actually exists, how many people have it, if it is exclusive to humans and not really having a good philosophical grounding for (assuming multiple separate consciousnesses could exist) whether in practice that is the case of if the universe only have one big super-contagiousness that happens to be well partitioned. Also what is the nature of time as a bonus, because that one is quite gnarly and has lots of implications for the other questions - there arer lots of things about time that could be true but we would be unable to perceive. Once you have answered all those questions to taste, you are now prepared to engage in unending argument with people who picked any alternate combination of answers.

Is there some particular reason why this debate isn’t squarely in the spiritual/religious/personal/subjective building on campus and zero in the science building? I mean, these are all fascinating questions in a “let’s smoke a joint and talk about the meaning of life” sense, I’ve had many such conversations (both with and without the joint) and enjoyed all of them that were of that tenor. And I can see there being a building on campus between the other two where the topic is ethics and morality: how rigorous can we be about what constitutes acceptable behavior, compassionate behavior, empathetic behavior, kindness and decency. Those things seem much more amenable to some level of rigor: I certainly hope that some version of those ideas can be rigorous enough to admit a consensus, but that seems like a way more realistic goal than defining consciousness. It still poses hard questions: is it ok to eat animals? That’s controversial but seems at least in principle amenable to scientific study of apparent pain or suffering and strategies for minimizing or eliminating it entirely. I have a sinking suspicion that the real definition of “conscious” is “seems a lot like me”.

  You might be being facetious, but just in case - academic philosophers generally aren't in the business of smoking joints while talking about the meaning of life, or anything like this (even without the joint). They're generally focused on making principled arguments for views, including views on consciousness. And the debate is primarily a philosophical debate, not a scientific debate, if that's what you're asking. And I'm not sure that ethics is particularly more "scientific" than philosophy of mind. There's a case to be made that scientific study of pain is relevant to the morality of eating animals, yes, but there's also a case to be made that science is relevant to consciousness, e.g. the science related to IIT. And in both cases, the science is relevant but doesn't even come close to solving the issue.

  Science generally maintains silence in these sort of discussion in my experience, there isn't a lot it has to say and I don't think any of the facts are controversial. There aren't really any questions here about observable phenomenon. But scientists also enjoy philosophy and it is an easy topic to have an opinion on. And arguing is fun for its own sake, although some people seem to be motivated by fear of their perception of reality being challenged.

  I'm not sure if you're dunking on "spiritual/religious/personal/subjective" stuff, but the hard question of consciousness is, in some ways, the most important question of all. Far more important than "science" questions like "what is dark matter?" Literally our entire civilization is built on the idea that humans have qualia and therefore causing harm to humans is often unethical. If we were to somehow come to believe that consciousness is just an illusion--no more than a biochemical phenomenon, and no more special than transistor switching--then we would usher in a dystopia in which any horror inflicted on people is potentially justifiable and even necessary. The rise of LLMs is forcing us to confront this head-on. LLMs can't be conscious--they are literally just matrix multiplication. But if LLMs can act like humans and not be conscious, then maybe humans aren't really conscious either.

    > But if LLMs can act like humans and not be conscious, then maybe humans aren't really conscious either. Isn't this like saying "if the man in the Chinese room can act like he understands Chinese and not understand Chinese, then maybe nobody understands Chinese."?
    - j16sdiz 3y ago
      Yes. And that is one of the reasons why Chinese room thought experiment is interesting. We know how a Chinese-understanding human would respond -- they respond exactly like the room does -- but we don't know if he actually understanding anything.
      - knightoffaith 3y ago
        If you understood Chinese, you probably wouldn't have any doubt about whether you understood Chinese or not. And it seems incredibly strange to think that only you understand Chinese and nobody else does.

    Why does ethics need to be based on consciousness anyway? Can't you just stipulate your baseline requirements and then enforce them by any means necessary? Are the aesthetics not "cosmopolitan" enough?

Consciousness, at its simplest, is awareness of internal and external existence. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes any kind of cognition, experience, feeling or perception. It may be awareness, awareness of awareness, or self-awareness either continuously changing or not.

  People have discussed various deities for centuries, and most of those don't seem to mind whether they exist or not. Also, many concepts have wildly varying ways of "existing". As a random example, a Mandelbrot fractal exists as a simple algorithm, but also as a concept related to (possibly beautiful) images. Which of these two is the proper or fundamental perspective to "understand" fractals better? Would studying the images be helpful to derive the algorithm if you lost its description? It's probably more helpful to study something else entirely to understand fractals better. And fractals are probably child's play compared to consciousness.

  > Also consciousness has an effect on physics for the same reason. I don't think that is correct. If physicists are alleging that physics works differently when we literally turn our back then that is something they should spend more time publicising. What I assume you are referring to is that, in practice, to observe something experimentally we have to interact with it (eg, to record the velocity of an object a laser or something has to bounce off it). Ie, it is impossible to do an experiment without interacting with the subject of the experiment. The physics doesn't change based on consciousness, it is just a comment on the limits of what experiment is capable of. > It seems likely that it exists, because why would we discuss it? We discuss lots of things that don't actually exist. Most mathematical objects don't exist as far as we can tell, and even if the universe is infinite it is almost certainly not big enough to contain the bigger infinities the mathematicians can dream up unless there is a lot going on that we aren't getting hints of in our observations. And we won't ever settle the question of whether randomness exists. It isn't possible to rule out the theory that the universe is all just a simulation and built off a pseudo-random function. Theoretical random processes are still a foundation of modern society. Something not existing doesn't stop us from theorising how things would work if it did exist. The question really comes down to whether it is a quirk of evolution that results in a convincing illusion or an actual thing.
