special issue of Entropy, "Models of Consciousness." I'm the physics half of the team, but the hard problem of consciousness long ago convinced me that science wasn't sufficient to finish my worldview :-)
Thank you, RUTA, this is a very interesting paper, your attempt to bring together the radical empiricism of W. James with the adynamical 4D blockworld approach to physics is very appealing and makes a lot of sense. Apparently I did not understand your treatment of adynamical global constraints in my previous post, I now have a better understanding.
I do have one question though regarding the first philosophical part of the paper. In your representation the most ontologically fundamental level of reality is the “Neutral Pure Presence”, which you interchangeably call “formless consciousness”. Bit does not it make your platform to be implicitly idealistic, not in the traditional sense of idealistic monism, but as a sort-of a more contemporary reformulation of it? I understand that calling it “neutral monism” would be more consistent with historical development of James/Russel’s philosophy which they themselves positioned as “neutral”. Still, claiming that the Neutral Pure Presence is not inherently “mental” does not automatically make it entirely “neutral”. Yes, it is neutral with respect to the traditionally understood dichotomy of material and mental. However, it is still “consciousness”, or more precisely, “awareness” as an ever-present invariant or substratum of any conscious experience. Obviously, there must be a common most fundamental "substratum" to all POs for them to be able to interact, and your choice of the substratum seems to be the "Presence", "formless awareness", rather than some other kind of noumenal substratum of unknown entirely neutral nature. This is a very natural parsimony to adapt because, first, it does not call for any additional hypothetic metaphysical reality other than what we already have available in the empirical data of conscious experience, and second, it would otherwise run again into the hard problem of consciousness requiring an explanation of how awareness with its ability to experience qualia could emerge from a neutral substratum that lacks any awareness. But would not it bias your platform towards idealistic monism rather than towards the neutral one? Of course the question is purely linguistic and there is nothing wrong with calling it neutral, it’s just a matter of more clear positioning of your view within a proper category of ontologies.
On another note, the Neutral Pure Presence ontology based on radical empiricism is not new, in fact it is very ancient with origins in early Buddhism and particularly in the Dzogchen school of Buddhism. In case if you don't know that already, you would be amazed to find how similar the worldview outlined in the ancient Dzogchen texts (such as Longchen Rabjam’s “The Treasury of Dharmadhatu” or "The Treasury of Abiding") is to W. James worldview, although of course they are presented in the framework of entirely different cultural content with entirely different practical purposes (which is spiritual practice as opposed to philosophical study for W. James). The core point of Dzogchen (and Buddhism in general) was that the empiricism and the Neutral Pure Presence (which is called “Rigpa” in Dzogchen) is not only a more adequate cognitive way of perceiving the reality, but it is also psychologically beneficial and spiritually transformative. This due to the fact that the sense of separate self (as a seeming subject of the experience of seeming objects), which is a cognitive basis of ego with its complex of egoic behavioral patterns, gets dispelled and transcended with clear understanding of its nature as simply a fabricated mental construct that does not refer to any actually existent entity of a "separate self". Disintegration of a false sense of separate self and discovering the underlying unity and non-duality of the reality of the Neutral Pure Presence leads to the disintegration of the egoic mentality and egoic cognitive and behavioral patterns in the course of the spiritual practice.
The Western philosophy rediscovered it in the works of Hume, James, Mach and Russel, although approaching it from purely philosophical point of view. But there have not been any attempts to reconcile this ontology with physics until recent years. Your variant is one of them and it looks very promising. The other one is Donald Hoffman’s conscious realism with his theory and mathematical model of interacting conscious agents, but he tries to use a different mathematical platform.
