Erik P Hoel,
Thanks for your kind comment. You note that consciousness is the 'secret sauce' and believe it does not apply to such things as bacteria or a sponge, lacking neural nets, or plants. As you know I posit that a universal consciousness field interacts with neural nets, but I have in previous comments and essays been more specific in that the field interacts with mass in motion. In this sense bacteria, sponges, and plants are composed of cells; cells are incredibly complex organisms, with many moving parts (see Alberts, Molecular Biology of the Cell):
Flows through nuclear pores, Myosin, a motor protein that moves along microtubules, vesicles that flow through the cell, ATP pathways, DNA polymerase sliding along DNA strands, Helicase enzymes that can move along DNA and RNA, floating lipid rafts, the dynamics of endocytic vesicle formation, protein pumps, filament dynamics applied to both actin filaments and microtubules, cytoskeletal rearrangements, the mitotic spindle and cell division, RNA splicing by spliceosome, ribosome producing factories, protein folding, molecular chaperones, transcription of proteins, the list is endless!
There is no reason that I can think of to suppose that a universal consciousness field would be dormant until the organism develops neural networks. Living cells are incredibly dynamic organisms, and the consciousness field as I envision it operates on momentum density, not mass per se. Thus a field that embodies awareness and volition would have quite a playground in a living cell. Even 'logic' is there, in spades, but the consequent 'intelligence' that follows would be a different order than the 'thinking processes' that depend on neural net pathways. Yet splicing and editing DNA sequences, etc, certainly constitutes some type of intelligence!
Lacking such a field, one has to postulate almost an infinity of trials and errors, and any in-depth knowledge of cell machinery argues strongly against the probabilities of billions and trillions of atoms "accidentally" constructing the living cell, regardless of 'survival of the fittest'. And note that every cell that did not survive is lost to perpetuity; perhaps some of its pieces can be recycled, but the process of assembling them still has to begin again from scratch.
Thanks for reading and asking an excellent question that allowed me to treat aspects that were beyond my essay.
Best regards,
Edwin Eugene Klingman
