Gertie, I'd like to understand what you mean here. You say that emergence "doesn't happen in nature, except when minds are already a component (like your example which requires minds playing the part of the bridging/causal mechanism)." Should I take it from this that you subscribe to an Idealistic metaphysical position rather than a materialist one? If so, I'm wondering what evidence there is that leads you to idealism. Why do you think that the universe is all mind-stuff rather than material stuff. If there were no minds do you think the universe would cease to exist?
The sentence before the one you quoted should've made it clear I was referring to
Strong Emergence there. I'm saying there are no cases of
Strong Emergence in nature, unless minds are part of the components. Which suggests there's something special going on.
There are definitional probs around the term 'emergence' which makes it confusing. But I take the key element of emergence as regards Philosophy of Mind as being the other side of the coin to reducibility. In that monist Physicalists say that the universe in all its complexity and innumerable properties emerged from the fundamental particles (ontological stuff) interacting in ways which 'follow the laws of nature' (causality). Just these two things - Fundamental Physical
Stuff interacting
Causally according to Fundamental Forces can account for everything which exists and everything which happens. And likewise the entire universe can similarly be reduced
ontologically and causally to the Standard Model of fundamental stuff/particles and fundamental causes/forces.
Physicalism says that's how nature works, as I understand it, and I call that Weak Emergence. Meaning the emergent property is ontologically and causally reducible to its parts and their interactions. (Particles and Forces).
As opposed to
Strong Emergence where if you reduce something to its parts and interactions, there is still something left over which is unaccounted for. That's the magic aspect of Strong Emergence.
So if we fully understood how brains physically work, we could reduce them in such a way that all the physical components and causal interactions can be accounted for. And that would explain how brains physically work. But when we do that, we still have this left over unaccounted for novel property which is phenomenal experience. And reversing that, Physicalism wouldn't be able to deduce or predict that the novel property of conscious experience would emerge from that arrangement of those components. There's an 'explanatory gap' there.
If we take the lighters at a concert example, it's not like the Weak Emergence of the novel properties of say oceans emerging from the interactions of H2O molecules. Because the causal bridge between the lighters staying in pockets and then lighting up is people deciding to light them. Without that minded causal intervention, the lighters would remain in the pockets.
Does that help, or is it just more confusing?
As to whether this 'explanatory gap' can ever be explained by Physicalism, or it turns out that's the wrong track, as I said I don't believe we are in a position to know that. Physicalism at least gives us a framework, and something (brains) to observe and poke.
