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

Quantum Consciousness If no theory of
consciousness based on classical Physics is satisfactory in explaining how
consciousness emerges from the electrochemical activity of the brain, then
maybe the problem lies with classical Physics. Physicists began in the 1920s to
advocate an approach to consciousness based on 20th-century Physics
rather than classical Physics. Loosely speaking, the point
is that consciousness is unlikely to arise from classical properties of matter
(the more we understand the structure and the electrochemical fabric of the
brain, the less we understand how consciousness can occur at all). But, for
example, Quantum Theory allows for a new concept of matter altogether, which
may well leave cracks for consciousness, for something that is not purely
material or purely extra-material. Of course, the danger in
this way of thinking is to relate consciousness and Quantum Theory only because
they are both poorly understood: what they have in common is a degree of
“fuzziness” that allows us to tinker with definitions. The advantage of Quantum
Theory, though, is that it allows for "non-local" properties and
provides a framework to explain how entities get "entangled",
precisely the phenomena that electrochemical brain processes are not enough to
explain. The unity of consciousness
is a favorite example. A conscious state is the whole of the conscious state
and cannot be divided into components (I can't separate the feeling of red from
the feeling of the apple when I think of a red apple). Newton's Physics is less suitable than Quantum Theory for dealing with such a
system, especially since Bell's Theorem proved that everything is permanently
interacting. Indeterminate behavior (for example, free will) is another
favorite, since Heisenberg's principle allows for some
unpredictability in nature that Newton's Physics ruled out. And, of course, the
mind/body dualism reminds Physicists of the wave/particle dualism. In fact,
Descartes' dualism is less credible
within the framework of Quantum Physics because, in Quantum Physics, matter is
ultimately not a solid substance. Back to the beginning of the chapter "A Physics Of Consciousness" | Back to the index of all chapters |
