This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
I recently learned about Sir Roger Penrose's research about Qualia. Then I formed my own conclusion of one of the universal truths;
That the "0th Dimension (The Nothing) Emerges/Balance All Infinite Possibility Across The Conceivable & The Inconceivable Reality"
I wrote an essay on it, as well as a wrap-up of our future. What do you think?

It always annoys me was 'esteemed' physicists venture into woo. That is a sign they ran out of ideas or are unserious about research and should retire to let the next generation of competent researchers in. This guy way overrated relative to his contributions.
Qualia always struck me as the basic material computation within biological systems. There's nothing magical about it.
If you begin things with the basic idea that consciousness is just at bottom, information processing at the level of the brain, that provides an easy pathway from hereon out to understand this. Whenever computers process information, there's always "something it's like" to be the computer doing that. That's just an inevitable consequence of computational task itself. This is just never experienced by anyone, unless the computation also includes a computed person that's experiencing it. When a computer experience's something, it's because it's computing the experience of that thing.
If you were to start with a simple visual process for example, where a computer needs to discriminate between areas of a space that are light or dark (say you're traveling to one trajectory and not the other), this will always be experienced in some way and necessarily so. The geometry that's being computed will be felt, and there will be something different about "what it's like" to be looking at a light area or a dark area. Because it couldn’t be otherwise. How could it? So there's nothing "extra" to explain about qualia. And the exact way this is experienced will depend on the computational circuit, it’s physical arrangement and how it behaves, etc. Other philosophers have reasoned the same way (including Dennett, Pat Churchland, etc).
Qualia, Consciousness, Sapience etc. all strike me as conversation starters that are sufficiently vague yet overloaded with implied meaning to forever escape any demands for rigor or practical application. A thousand years from now we'll probably have harnessed the power of the stars to feed unimaginably powerful thinking machines and the best insight they'll have into those topics will be something like "It's whatever the fuck you want it to be".
Of course, I'm a barely literate peasant. It's probably all perfectly sensible. But man does it look like so much pseudobabble from here.
Actually not vague terms at all!
If you've ever pricked your finger and felt pain, that's a qualia.
If you've ever felt a sensation of hot or cold, that's a qualia.
If you know what the color blue looks like, and how it looks different from the color red, that's a qualia.
It's just conscious experience. That's it. It's that thing you have when you're alive and experiencing things, and that you lack when you're dead. Its nature might be mysterious, but the concept itself is about as straightforward as you can get.
I think what's happening is that people correctly notice that the people who like to use the word "qualia" also like to use other strange terms like "property dualism" or "epiphenomenalism" or "p-zombies" that seem to refer to very strange ideas. So they get nervous and they assume that any talk of consciousness in general must be BS. Independent of your evaluation of the philosophical literature on consciousness, it would simply be a mistake to write off the idea completely. That would be like saying that because people have come up with crank theories of physics before, physical reality itself must be a "vague" or "nonsensical" idea.
The rigor is that you know what pain is, that's the rigor.
As for "practical application", that seems like a category error. It's not clear how you can derive from first principles, starting with our current best theories of fundamental physics, that anyone is conscious at all. And yet we know they are. Surely you can appreciate that it's intrinsically interesting to try and figure out why that's the case?
But it's not. See above.
If you have specific examples in mind, or want to talk about specific terms or ideas, I'd be happy to try to explain them.
I do not think that this will get you anywhere. At most, you can convince me this way that I have qualia. But my temperature detection circuit is nothing special, an insect might have something rather similar. Does it have qualia? What if I replace it by electronics running an identical neural network and a temperature sensor? What about a rock which gets slightly larger when it is warm?
If qualia is a useful property systems of matter can have or not have, then you automatically run into p-Zombies.
At the end of the day, I want concepts which describe reality and pay their rent in anticipation of future events. The pH value of aqueous solutions is a good (if limited) concept. I can measure it, and it will give me good predictions about which reactions will tend to take place e.g. if I decide to take a swim in it.
Qualia is not such a concept. It does not make falsifiable predictions. There is no test to determine if a dog or a LLM has qualia.
I'm not certain this refutation of qualia's validity as a concept really works unless you also throw out a large portion of commonly-used language, in other words, it proves too much. "Qualia" is just meant to be a descriptive term for a phenomenon that is experienced and individually confirmable. Claims about why qualia arises and whether it is present in someone or something else are unfalsifiable and do not meet the standard for scientific inquiry or analysis, you could argue that debating that is a waste of breath (and I may even agree, actually), but that doesn't invalidate the concept of qualia.
The structure of this argument is kind of like stating that we should discard the concept of "feelings", for the very same reasons why qualia would be invalid. Or any kind of evaluative statement, really; "good", "bad", "immoral". Sometimes we just want to be able to refer to things. People aren't making testable predictions every time they open their mouths, and as such the purpose of language serves functions outside of making such statements. Hell, people even do this in the scientific world - for example debating interpretations of quantum mechanics is a common pastime among physicists, many of which are not testable and do not meet the criteria for science.
