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

Consciousness
Creates Reality If a wave collapses (i.e., a particle assumes well-defined
attributes) only when observed by a conscious being, then Quantum Theory seems
to specify a privileged role for the mind: the mind enters the world through
the gap in Heisenberg's uncertainty principle.
Indeed, the mind "must" exist for the universe to exist,
otherwise nobody would be there to observe it and therefore the world would
only consist of possibilities that never turn into actualities. Reality is just
the content of consciousness, as the Hungarian physicist Eugene Wigner pointed out (The Problem
of Measurement, 1963). Of course, mind
must therefore be an entity that lies outside the realm of Quantum Theory and
of Physics in general. The mind must be
something special that does not truly belong to "this" world. Wigner pointed out that to every action there is a reaction: why
shouldnt there be a reaction to a conscious observation of a physical
phenomenon? If a phenomenon exerts an influence on my consciousness when I
observe it, then my consciousness must exert an influence on the phenomenon.
Otherwise the fundamental tenet that to every action there is a reaction is no
longer true. Wigner observed that Schroedingers equation is linear, but
would stop being linear if its object were the very consciousness that
collapses the wave. Therefore, Schroedingers equation (which is linear) would
result in a non-linear algorithm that may justify the minds privileged status. If the collapse
occurs only when observed by a conscious being, if the collapse occurs at the
border between mind and matter, as Wigner believes, then the evolution of the universe changed after the
appearance of human beings (there was no collapse anywhere before mind
appeared). Undeterred by this objection, the US
physicist John Wheeler believes that ours is a
"participatory" universe, one in which consciousness participates in
creating reality. The observer and the phenomenon are engaged in a creative act
that yields reality. Consciousness does not create reality. Consciousness's role
is extremely limited: it can't even choose which of the possibilities contained
in the wave function will become reality. It can only "precipitate"
reality out of many possibilities. Which possibility becomes reality is up to
nature. Nonetheless, Wigner and Wheeler believe that consciousness is crucial to creating
reality: as limited as its contribution is, without it there would be no
reality, only possibilities. Wheeler even speculated that the rise of consciousness
retroactively determined the history of the universe because it collapsed the
mother of all waves that had never been collapsed before, thereby fixing every
single event in the previous life of the universe. Quantum
theoretical effects could be considered negligible if they only affected
particles. Unfortunately, Erwin Schroedinger, with his famous cat experiment,
established that Heisenberg's uncertainty affects big
objects too. Basically, Schroedinger devised a situation in which a quantum phenomenon causes the cat
to die or stay alive. Since any quantum phenomenon is uncertain, the cat's life
is also uncertain: until we look at the cat, the cat is neither alive nor dead,
but simply a wave of possibilities itself. (A popular objection to
Schroedingers argument is that the cat can never be in a superimposed state
because every big object, by definition, is never isolated, it is always
entangled with the rest of its surroundings, and therefore it is collapsed all
the time). Back to the beginning of the chapter "The New Physics" | Back to the index of all chapters |
