These are excerpts and elaborations from my book "The Nature of Consciousness"

Quantum Self Theory The British psychiatrist Ian
Marshall (Consciousness and
Bose-Einstein condensates, 1989) showed similarities between the holistic
properties of condensates and those of consciousness, and suggested that
consciousness may arise from the "excitation" of such a Bose-Einstein
condensate. In Marshall's hypothesis, the brain contains a Froehlich-style condensate, and,
whenever the condensate is excited by an electrical field, conscious experience
occurs. The brain maintains dynamical coherence (i.e., the ability to organize
millions of neural processes into the coherent whole of thought) thanks to an
underlying quantum coherent state (the Bose-Einstein condensate). Furthermore, Marshall thinks that the collapse of a
wave function is not completely random, as predicted by Quantum Theory, but
exhibits a preference for "phase difference". Such "phase differences" are the
sharpest in Bose-Einstein condensates. This implies that the wave function tends to collapse
towards Bose-Einstein condensates, i.e. that there is a universal tendency
towards creating the living and thinking structures that populate our
planet. Marshall views this as an
evolutionary principle inherent in our universe. In other words, the universe
has an innate tendency towards life and consciousness. They are ultimately due
to the mathematical properties of the quantum wave function, which favors the
evolution of life and consciousness. Marshall thinks we "must"
exist and think, in accordance with the strong anthropic principle (that things
are the way they are because otherwise we would not exist). Marshall offered a solution to the
paradox of "adaptive evolution", discovered by the British physician
John Cairns (The origin of mutants, 1988): some bacteria can mutate very quickly, way too quickly for Darwin's theory to be true. If all genes mutated at that pace, they would
mostly produce mutations that cannot survive. What drives evolution is natural
selection, which prunes each generation of mutations. But natural selection does
not have the time to operate on the very rapid mutations of these bacteria.
There must be another force at work that "selects" only the mutations
that are useful for survival. Marshall thinks that the other force is the wave
function's tendency towards choosing states of life and consciousness. Each
mutation is inherently biased towards success. His wife, the US philosopher
Danah Zohar, expanded on his theory.
Zohar views the theory of
Bose-Einstein condensation as a means to reduce mind/body dualism to
wave/particle dualism: the wave aspect of nature yields the mental (conscious
experience), whereas the particle aspect of nature yields the material. Zohar is fascinated by the behavior of
bosons. Particles divide into fermions (such as electrons, protons, neutrons)
and bosons (photons, gravitons, gluons). Bosons are particles of
"relationship", because they are used by other particles to interact.
When two systems interact (electricity, gravitation or whatever), they exchange
bosons. Fermions are well-defined individual entities, just like large-scale
matter is. But bosons can completely merge and become one entity, more like
conscious states do. Zohar claims that bosons are the basis for the conscious
life, and fermions for the material life. The properties of matter
arise from the properties of fermions. Matter is solid because fermions cannot
merge. Likewise, she thinks that the properties of the conscious mind arise
from the properties of bosons, because bosons can share the same state and they
are about relationships. This would also explain how
there can be a "self". The brain changes all the time and therefore
the "self" is never the same. I am never myself again. How can there be a "self"? Zohar thinks that the self does
change all the time, but quantum interference makes each new self sprout from
the old selves. Wave functions of past selves overlap with the wave function of
the current self. Through this "quantum memory" each new
"quantum self" reincarnates past selves. Back to the beginning of the chapter "A Physics Of Consciousness" | Back to the index of all chapters |
