Yup, I used the term “qualia” in 2016 (in response to someone else making an argument that used the term). I don’t always pick every possible fight :-).
(In that case, turchin was making another specific argument and used the word “qualia” in passing. I disagreed with the other specific argument and argued against that. The specific word “qualia” was a side issue at most. Here, the specific point at issue is whether everyone needs to agree that “we have qualia”.)
You asked for a definition of “matter” and I (1) gave a list of examples and counterexamples and near-the-boundary examples, (2) prefaced with an explicit note that this was preliminary handwaving, (3) followed by an attempt at a precise definition distinguishing matter from not-matter. You haven’t done any of that for “qualia”, just given a list of examples, and that (not the fact that you did give a list of examples) is what I was complaining about. “It’s easy to give examples … I’m not so sure that that means it’s easy to give a satisfactory definition”.
Your accusations of wilful ignorance and/or laziness
Yes, I could look up definitions of “naïve realism” or of “qualia”. As it happens, I have. They don’t tell me what you mean by those terms, and definitions of them do not always agree with one another. Which is why I keep asking you what you mean by terms you are using, and get frustrated when you seem reluctant to tell me.
For instance, here we read that “the naïve realist claims that, when we successfully see a tomato, that tomato is literally a constituent of that experience, such that an experience of that fundamental kind could not have occurred in the absence of that object”. Here we read that “naïve realism is the human tendency to believe that we see the world around us objectively, and that people who disagree with us must be uninformed, irrational, or biased”. In a comment of yours elsewhere in this thread you say “People generally and incorrectly assume that colours are objective properties (hence the consternation caused, amongst some, by the dress illusion). That’s called naive realism, and it’s scientifically wrong.”
(I remark in passing that you also said that the difference between two people who agree that people experience things, one of whom says that we have qualia and one of whom doesn’t, is that the latter has to be a naïve realist; if you are in fact claiming that “we have qualia” means something that is straightforwardly implied by “colours are not objective properties of the objects whose colours they are” then, yay, it turns out that I believe that we have qualia and we can stop arguing. But I’m pretty sure this will not in fact be enough.)
These three things are not entirely unlike one another, but no two of them are the same. Your comment is offering an example rather than a definition, but it is not in fact an example of the first definition and I’m doubtful about its being an example of the second.
Or I could look up “qualia” in, say, the MIT Encyclopedia of Cognitive Science, whose entry for that subject begins as follows—my annotations in square brackets.
The terms quale and qualia (pl.) are most commonly used [“most commonly”, so plainly what is about to follow is acknowledged not to be a definition that covers everyone’s use of the terms—gjm] to characterize the qualitative, experiential, or felt properties of mental states. [“most commonly used to characterize” is quite a long way from defining anything—gjm] Some philosophers take qualia to be essential features of all conscious mental states; others only of sensations and perceptions. [Again, not everyone uses the word the same way. -- gjm]
Here we have clear acknowledgement that the term is used differently by different people, and (I think deliberately) something that falls short of an actual clear definition.
Or I could go to an ordinary dictionary, say the superlative Oxford English Dictionary, the relevant part of whose definition reads: “a quality or property as perceived or experienced by a person”. Which seems to presuppose (at least one version of) “naïve realism”: these qualities or properties are presumably of things in the external world and this definition seems at risk of importing the objects themselves into our qualia.
(But: people have experiences; often those experiences are “of” qualities or properties of objects in the world around them; if you don’t consider that to be acknowledging that “people have qualia”, what do you think is missing other than a specific shibboleth-phrasing?)
Actual discussion of the issues
I’m not sure whether “that which is ineffable, incorrigible, irreducible and repeatable” is a (presumably very partial) description of what you mean when you talk about qualia, rather than just a random list of adjectives. If it is, then it’s a nice illustration of why I am reluctant to say (as I think you want me to) “yes, sure, I agree that there are qualia”. I strongly suspect that what most people who talk about “qualia” mean when they use that word goes way beyond the specific handwavy examples they offer, and I don’t want to be thought (by them or by others) to be endorsing any of the other stuff until we’ve talked about that other stuff explicitly. I agree with you that people experience things; I do not think it’s clear that they have experiences, or equivalence-classes-of-experiences, or whatever, that are ineffable, incorrigible, irreducible and repeatable. Maybe they do. I’m not saying they definitely don’t. Just that those further claims are substantial claims, and that I think they are the sort of thing that “qualia” commonly means even to people who say “oh, no, all I mean by qualia is that stuff that happens when you look at a red thing”, and that part of the difference between “I agree that people experience things” and I agree that people have qualia” is that the latter is liable to give the impression that I endorse those substantial claims, and that if you want my assent to those claims then we actually need to discuss them.
Saying that you’re going for a minimal and common-sense approach is all very well, but in practice people are not that great at using words that have connotations in ways that abandon those connotations. This is also why I don’t think an atheist should play along if a certain kind of theist says “well, let’s just take ‘God’ as a sort of shorthand for humanity’s highest and best aspirations”, and I don’t think a creationist should play along if a biologist says “look, all ‘evolution’ means is change of allele frequencies in populations”.
You distinguish (I think this is the nearest you get to answering my question about what exactly you mean by qualia) between two kinds of things we might say about experience: “objective” (things happen differently in the brains of different people) and “subjective” (things seem different to different people) and say it’s the subjective side you’re concerned with. I am not actually convinced that “things seem different to different people” is a very meaningful proposition—that seems to presuppose some way of comparing experiences across people, and while obviously it’s easy to say that my experience of looking at a green thing is not the same as your experience of being struck gently on the head with a golf club I don’t really know what it would mean to say that my experience of looking at a green thing is or isn’t the same as your experience of looking at a green thing, and I strongly suspect that there is no answer.
Still, for sure people experience things and we can e.g. ask someone what they feel like. Does that mean that I agree that “people have qualia”? If not, what do you think is missing other than a specific shibboleth-phrasing?
