So this question is more towards those who don't find physicalism convincing anymore: How does matter arise from consciousness?
And in this case consciousness is the ontological primitive — TheMadMan
Hmm this is a challenging notion to argue but I thank you for the task. It seems fun. I'm going to ad lib with this one.
So lets say for arguments sake consciousness as an ontological primitive is an spontaneous impulse (action potential) that wishes to create tracks or patterns (thoughts) so that it can develop a store (memory) and thus perception of the passage of time (based on memory of the past) and by proxy anticipation (or the "future" ), as well as a sense of presence (the present), it requires some substance to store information and making these thought tracks/patterns - ie for making memories.
Cue matter. If energy is the impulse of thought - potent, flexible, malleable, changeable, creativity, imagination, then matter is it's rigid or crystalline counterpart - the memory generated.
And as we know the two are related (equivalent) - by Einstein equation (e=mc2).
If consciousness is a fundamental, then the hard problem of consciousness/or matter (I think they are the same in this case) cannot be found in our brains, and is not that hard at all, it would instead be a reevaluation of the e=mc2 equation with the assumption that (c2) represents the gap (or "problem" of unifying the 2 entities: thought (energetic impulse, and memory - matter: the anatomically stable structure, the neurons).
Matter is thus the form of energy with properties of stability, it takes a solid and structured or patterned form and then remains that way until acted upon again. Just as memories take form and are slowly altered every time we revisit them with our conscious attention.
Perhaps con"solid"ation of memories also involves gravity which draws in scattered "memories" and condenses them into geometric relationships/associations (orbits, solar systems etc - perhaps a basic for logic or reasoning. Organisation, complexity. Negative entropy).
So really the question would be how does thought in this case (energy - the electricity or light coursing and rippling through the system as it thinks, acts and develops) become matter (the memories formed) and I would suggest the answer lies in the e=mc2 formula.
Speed is a relationship between time and space (distance). It is also the factor that distinguishes matter from energy - (c) the speed of light (which is energy, so it's a "self-referential" equation - apt for consciousness or "self" no? ).
In order for energy to become matter, or "thought impulse" to become "memory", time and distance must change rapidly. As the equation would suggest.
Perhaps with some relativistic expansion-dilation type of change.
A given quantity of energy or "thought" could hurtle out (space) , dissipate (entropy) and it's rate of change (with relation to time) might slow and become more stable, less chaotic, and thus precipitate into an emergent form that is much less excitable and dizzyingly zippy/fast (matter).
This primitive consciousness could be said then to be a dynamic relationship between the 4 fundamentals: energy, time, space and matter (each dependant on the qualities/properties of the others for existence and their "separable individual behaviours" ).
I hope this satisfies your request for a consciousness based emergent physicalism answer that you might enjoy contemplating.
It's at most an analogy/metaphysical, metaphorical or pseudo-physics description.
It has no scientific "proof" from a purely physicalist perspective, but I guess resolving the physical with the conscious (hard problem) wouldnt come just from objective physical explanations would it? I think it could be seen as reasonable despite not being scientific.
That I imagine physicalist will detest with every inch of their "material bodies." But I don't shy away from a bit of thought paintings/art regardless of their disgruntledness
