Brain (biochemical and systemic organic) and subconscious dominance over consciousness is amongst the most fundamental limits to human evolution. Is that what modern neuroscience is telling us?

Possibly what can be conceived as the cosmic consciousness, that is to say the organization of energy (as represented by the strings theory) spontaneously emerging from quantum vacuum: absolute nothing [to] Big Bang [to] inflation [to] quarks and other particles [to] hydrogen [to] … complex nucleus (elements) [to] organic complexes … and finally to the building of organisms … intelligence … and consciousness.

However, the metaphysical (and scientific) problem is to determine if our capacity to “know” what we’re doing (well … maybe this capacity is very limited) is acting on our choices (free will), or, if it is limited to explain what our brain as a survival oriented organic system is doing, this with no effect on its behavior (no free will).

Surely, all electrons have Planck scale spin properties, and at the quantum level of reality perception, these properties are not without effects on axons networks coherence (no coherence=inefficient randomness). The question here is to distinguish between “having consciousness of reality as a meta phenomenon acting on brain activity” and it’s contrary, “having axons biochemical and electro-chemical reactions to senses controlling what we perceived and the way we react.”

"Taking a modern pan–psychist view in which protoconscious experience and Platonic values are embedded in Planck–scale spin networks, the Orch OR model portrays consciousness as brain activities linked to fundamental ripples in spacetime geometry."
