I'd like to discuss your take on the combination issue. It starts with your claim that life is what dissociation looks like. (I agree) This dissociation process or inner life occurs with the simplest forms of life.(I also agree) But you also said a neuron does NOT have an inner life and those two claims seem contradictory to me...etc.
It occurs to me that in respect of combination, there's a difference between the arising of life from the inanimate (abiogenesis) and the evolition of the simplest, unicellular forms of life into ever more complex multicellular organisms. There's a step change between the inanimate and the animate. What we perceive as inanimate appears to us as having no capcity to exhibit
all of the criteria of life (I can remember off the top of my head 5 of the 7 criteria of life I learned at school -- growth, metabolism, reproduction, excretion, and irritability -- there's a fuller exposition
here). Some inanimate things, like crystals, can be said to grow, but not in the same way that animate beings do.
We can construct no plausible schema for how the first cell came into being. Before it did, as far as one can determine, everything was inanimate. The first cell was already an enormously complex thing, and presumably already able to exhibit all the usual criteria of life. Today we can find no evidence of anything that is "partly alive", with the possible exception of viruses (which may well have appeared only after the first truly living organism and not represent an intermediary state).
Whatever, I believe that the first cell was the first example of dissociation in the sense BK uses the word, and a unicell cell can only grow so big. There is a difference of opinion as to what is the largest single cell, see
here); but in general to increase complexity, organisms have to exhibit an increase in the number of their cells as well as the number and type of relationships between those cells.
Some of the "third way of evolution" people seem to attribute to the cell a wide-ranging ability to "intelligently" direct its own living processes. At times it almost seems as if they're implying that the cell is vastly more intelligent than human beings; but if that's the case, human beings, indeed all multicellular organisms, represent a regression in intelligence or ability to process information.
In any case, what is being combined in multicellular organisms isn't necessarily an association of cells, each of which could live out their lives independently of the whole. Remove a cell from its milieu and it usually dies, because for some at least of its functions, it relies on other cells that remain as part of the whole. Thinking of vertebrates, for example, an excised liver cell can't function without the cells of the vascular system to provide nutrition, carry away wastes, and so on. The functions that an independently viable unicell can perform can't be carried out by a single isolated cell of a vertebrate. Instead, the living functions of the whole are distributed amongst the cells of the the various organs it possesses. Those that remain in the excised cell are only a partial selection of the functions of a free-living unicellular organism.
Of course, sometimes various kinds of vegetative or asexual propagation enable one cell to regenerate a whole organism, but these could be viewed as cases where the unicell, by dint of its previous association within a multicellular organism, possesses information in its genome that enables it to re-constitute the whole.
The thing about organisms, be they uni- or multi-cellular, is that they represent a single entity which acts in its own best interests, however distributed its various functions may be throughout its body: there seems to be a unified aim that governs its behaviour. IOW, it acts autonomously, at least when healthy; only when diseased does it act against its own interests - as evidenced by such things as cancer, and in humans, the counterproductive behaviours of various mental ailments such as schizophrenia, anorexia, OCD and the like.
In the usual evolutionary view, causation always has to be bottom-up; from the simple to the more complex. There can be no telos involved; it can't be known in advance what is being aimed for. Hence the insistence on the random mutation and natural selection of the Darwinian model. There isn't allowed to be a "pull" force rather than a "push" force, so to speak. There can't be a Mind At Large that has the will or desire (be that metaconscious or more instinctual), to explore the possibilties of its own being, which we perceive at least in part as matter and the processes we think of as energy and forces.
The central idea that MAL has, if I may put it that way, could be of a target to be strived for which almost always (disregarding for the moment phenomena such as DID) involves apparently unitary consciousnesses. And for whatever reason, that may involve the intricate interrelationships between what we perceive as cells. It may not be so much that an organism is an agglomeration of cells, each with an individual and independent awareness. It may be more the realisation, within the realm of possibilities of MAL's mental processes, of dissociated, progressively more complex, multicellular entities apparently capable of a degree of autonomy.
If such were the case, it could mean not so much that complexity arises through combinations of autonomous, less complex organisms; rather, the one thing that remained constant could be the striving in evolution towards an always unitary living being, the individual cells of which contribute to that end.
It's somewhat analogous to the engineer who has the idea of building a machine with a specific purpose right from the beginning. At first he brings together certain parts in a certain way, but they don't work together exactly how he wanted. So he elaborates, adding more and different parts, sometimes even discarding them so that he can get closer to his aim. His earliest efforts would be analogous to free-living unicells, and later efforts to progressively more and more complex interassociations between cells; but generally, (I'm excluding symbiosis from the analogy), at no stage would there be the aim of building a colony composed of separate individuals like ants and termites do. The aim would be to continue to work on producing the "ideal", autonomous living being.
The main apparent discontinuity in what we can perceive is between the inanimate and the animate, marked by the putative phenomenon of abiogenesis, which I take to be the signal of MAL's "decision" to begin to dissociate itself, and that appears to us as animacy. As I see it, the combination isn't of individuals, but of what appear to us to be the bodies of interdependent, non-autonomous entities that contribute to parts of the functionality of the whole.
The other side of the discontinuity is what appears to us as what we interpret as atoms, energy and forces, which is what physicalists think of as independently existing patterns and regularities of nature from which everything is made up according the possibilities of their interactions. Sensing increasingly that this is a shaky proposition, the only option that panpsychists have is to posit that individual elementary particles (which don't actually exist as such) possess consciousness that in chemical combination can lead to emergence of higher levels of consciousness.
I don't personally think that combination is compatible with idealism. IOW, autonomous animate wholes don't arise out of combinations of lesser animate wholes. Rather, the aim of autonomous wholes is ever-present and always guides from the top downwards. The cells of multicellular organisms have never experienced autonomy; only multicellular organisms as wholes can experience some degree or other of that. YMMV.
