Pattern-chaser wrote:QM isn't metaphysics, it's science. Or it was when I used Schrodinger's wave equation many years ago, to analyse the tunnelling of electrons through an insulating barrier. QM raises philosophical questions, yes. But it is still the best scientific theory we've ever created.
I think QM is deemed to be particularly relevant to philosophical questions about the interface between mind and matter, and dualism/non-dualism/monism etc because it brought into focus the fact (which had obviously always been there) that the observer of a physical system is itself part of the physical system.
Oh,
that is what the fuss is about.
The discovery that observation is active, not passive; no more '
impartial observers', at least in that sense. Thanks.

As far as I can gather, these non-dualism ideas start from the observation that divisions in Nature, including the division between observer and observed, can be changed depending on purpose. i.e. we impose divisions on Nature to the extent that they are useful to our current purposes. For example, for some purposes we conclude that the Earth is a thing. For other purposes we conclude that it is a large collection of smaller things. Therefore it is concluded (by those who are that way inclined) that those divisions are, like any system of classification, abstract and not real. Therefore it is concluded (by those who are that way inclined) that, ontologically but not epistemologically, the universe is just one thing and that "thingness" (if, by that, we mean real sub-things within the universe) has no place in an ontology.
Dualism has pros and cons, as do the alternatives. In theory, I see no reason to divide anything without good strong reasons, and I am aware of none. But in practice, I also know that human minds cannot digest LU+E (Life, the Universe and Everything) in one bite, so we must either not think about anything at all complicated, or we must practice reductionism, which is multiply-recursive dualism. We divide and divide until the parts we have are small and simple enough for us to hold in our minds. I think we understand this division is unjustified, but the fact is that we have no choice.
In some ways, where we can, we renounce dualism. In other ways, where we cannot, we do not. There's a bit of cognitive dissonance there.
My discussion with @Atla has not been about dualism directly, but about their claim that dualism has been "refuted" by science, or maybe by philosophy, I'm not sure. Of course it has not, but non-dualism currently holds the consensus, and I am quite happy with that. I have long accepted the tension between division (dualism) being unjustified, and reductionism (dualism) being necessary.
