> A much better analogy is that philosophy is not science in the same sense that alchemy is not chemistry, or astrology is not astronomy

Not at all. Astrology is irrelevant, whereas philosophy is quite relevant in the sense that it is an integral part of scientific activity and takes place despite certain people forgetting that they do it even while doing it.

> or banging on a hollow log with a stick is not playing the violin

Yes, I actually edited my comment to provide a better analogy: philosophy is not science in the same sense music is not drumming.

> Materialism is not the testable hypothesis. The testable hypothesis is "molecules is what causes us to flourish."

These follow from one another. If you claim that molecules are the cause of some phenomena taking place in your mind, which flourishing, self-actualisation, happiness, suffering, etc. all are, then you implicitly claim materialism.

For anyone who claims that mind-state is the cause, you can claim that it is in fact the consequence (or an illusion, as some do), and it will be your word against theirs.

That’s where it stops being a scientific experiment and becomes a higher-level philosophical argument where testability is, unfortunately, out of our reach, but we can still judge theories by their elegance and logical soundness.

> The way you falsify it would be to demonstrate some aspect of human flourishing that cannot be explained as the actions of molecules

As above, if you claim that there is some aspect of flourishing that cannot be explained as “actions of molecules” (I would be hard-pressed to ascribe any agency to molecules, personally) you would likely be implicitly adopting monistic idealism (or some sort of dualism, which I personally find dubious due to even more drastic lack of elegance than in monistic materialism), and that is not testable since to anyone who claims that mind-state is the consequence you can very simply point out how it can be the cause—and since neither way can be proven or disproven, it is once again a higher-level philosophical argument.

That argument is more fundamental and more important, actually, than predicting some molecular activity or the like; and before you object, using the fact that scientific method is as of now limited and unable to provide evidence either way can’t serve as a justification for calling the question itself unimportant if we were to have this discussion with any rigour and truth-seeking determination (as opposed to mere desire to socially signal or appear “right”).

> philosophy is quite relevant

I guess we'll just have to agree to disagree about that.

> you implicitly claim materialism

Nope. In fact, I actually do claim all of these things while at the same time denying materialism because quantum mechanics. Molecules don't really exist, just like the force of gravity doesn't really exist. Both are just very good approximations.

> For anyone who claims that mind-state is the cause

The cause of what?

You don't have to get into consciousness at all. Food and water, for example, are clearly integral to human flourishing, and you don't have to get into any metaphysical woo to defend that position.

> That’s where it stops being a scientific experiment

That's just nonsense. Malnutrition and dying of thirst obviously yield to straightforward scientific inquiry.

Like I said, if you want to argue otherwise, the burden is on you to demonstrate some aspect of human flourishing that does not yield to scientific inquiry. I'll bet you can't do it.

If you forget to drink water while working for many hours, you may feel dehydrated and poorly. If you remember to drink water, you feel better.

Drinking water clearly causes a change in your mind-state. However, drinking water is something you decide (or forget) to do, i.e. it’s obviously caused by your mind in the first place (or that of your partner or another person helpfully bringing you a glass). However, we can further speculate that said mind is, in turn, affected by certain chemical interactions (approximations of something external to those minds), and even call the general existence of minds into question. Yet further, we could treat that chemical reaction as, in turn, derivable from (or be a representation of) mind-states, yours or otherwise, further down the line.

You can see how as far as scientific method is concerned this gets nowhere very quickly—it’s unfalsifiable and outside of what scientific method is equipped to help us with (not a bug, since it’s by design).

Naively, it seems that best we could do is 1) acknowledge that uncertainty and perhaps 2) pick a point in the above chain, reason why to believe that point is not arbitrary, and explicitly adopt that as a philosophical position.

> I guess we'll just have to agree to disagree about that.

We can simply do that, though I did attempt to provide a justification for my position. Philosophy, whether done explicitly or implicitly, always informed the application of scientific method.

> we can further speculate that said mind is, in turn, affected by certain chemical interactions (approximations of something external to those minds)

Indeed, there is quite a bit of evidence to support this hypothesis.

> and even call the general existence of minds into question

Well, you can call anything into question, but there is quite a bit of evidence for the existence of minds.

> we could treat that chemical reaction as, in turn, derivable from (or be a representation of) mind-states

Well, I suppose we could, but again there is quite a bit of evidence that the causality of that particular mechanism (if I'm understanding you correctly -- you are being pretty imprecise here) runs in the other direction.

> You can see how as far as scientific method is concerned this gets nowhere very quickly

Sorry, no, I don't see that at all. AFAICT the way in which minds arise from chemistry is pretty well understood. In fact, it is sufficiently well understood that we are on the cusp of being able to create artificial minds that are not based on chemistry.

> Naively, it seems that best we could do is 1) acknowledge that uncertainty

Sorry, no, I don't see any uncertainty to acknowledge.

> I did attempt to provide a justification for my position.

Yes, but I think your attempt has failed.

> there is quite a bit of evidence that the causality of that particular mechanism (if I'm understanding you correctly -- you are being pretty imprecise here) runs in the other direction.

Not if you look thoroughly. There is no proof that causality runs[0] in either direction, and in all likelihood it would remain so for as long as the hard problem is unsolved.

> AFAICT the way in which minds arise from chemistry is pretty well understood.

That would be immensely groundbreaking, absolutely historical news that would eclipse LLMs, reverberate HN for months and would not pass either of us unnoticed.

> In fact, it is sufficiently well understood that we are on the cusp of being able to create artificial minds that are not based on chemistry.

Have you heard about the so-called Chinese room experiment or the concept of a philosophical zombie?

> I don't see any uncertainty to acknowledge.

That’s because you have adopted a philosophical position implicitly.

> Yes, but I think your attempt has failed.

You have not even attempted to object by providing a counter-argument, though.

[0] Side note: even though I am guilty of thinking that way myself, I find the whole notion of “causality running” smelling of Cartesian dualism and another inheritance of our religious past. A theory presupposing the existence of two different kinds of things (as in this case, mind vs. physical), while useful in its own ways, is necessarily less elegant than a theory that can manage with one.

> There is no proof

You need to read this:

Yes, it was [1]. Still is, as this work is on-going [2].

> Have you heard about the so-called Chinese room experiment or the concept of a philosophical zombie?

Yes. Have you heard of the Turing test?

For the record, the Chinese Room is based on the false premise that the Chinese Room is possible. It isn't. The person inside the room would be dead long before it emitted its first symbol. And philosophical zombies are IPUs [3].

> That’s because you have adopted a philosophical position implicitly.

No, I have adopted a philosophical position explicitly [4].

Perhaps you are unaware that I am the author of TFA [5]? Did you read it?

If you don’t like the word “proof” then replace it with the phrase “conclusive evidence”.

> Yes, it was [1]. Still is, as this work is on-going [2].

Sorry, how does any of that show that “minds arise from chemistry”?

> Yes. Have you heard of the Turing test?

Yes, and a Chinese room would pass the Turing test by its very definition.

Replace the person with a powerful CPU.

In this context a philosophical zombie is an instance of a Chinese room, which are fairly real things. Take a sufficiently advanced LLM, or an emulation of human brain, and you get one. (Showing that it is not a philosophical zombie would call for some conclusive evidence showing that the phenomenon of consciousness is caused by whatever entities feature in models from today’s natural sciences—so that manipulating them in a particular way is enough to cause consciousness to magically arise.)

> Perhaps you are unaware that I am the author of TFA [5]? Did you read it?

That slipped my mind after a while, but I don’t think it invalidates the discussion. I skimmed it back when it was posted and generally I have been familiar with the illusionist takes on consciousness for a while. As monistic materialism (as well as cartesian dualism) in general, they always strike me as inelegant and needlessly contrived. (When competing hypotheses cannot be falsified due to limitations of scientific method, beauty and elegance remain as qualities we can judge them on, and I find that beauty inversely correlates with the number of entities a given hypothesis must magically conjure into existence.)
