Quantum Physics & Dualism:
Is Orthodox Quantum Physics consonant with a Plausible Dualism?
The problem of the relation between mind and body is well known as a
difficult `world knot'. Over the centuries various monistic and dualistic
theories have been proposed, and the subject has had renewed interest as we try
to assimilate the implications of quantum physics. These implications may make
us re-examine our views of brains and bodies, but it is still not clear what
consequences they have for our understanding of minds. We may suspect that
quantum mechanics and consciousness are related, but the details are not at all

(essentially the same questions
Quantum Physics may be indeterministic about the detailed choices between
differerent outcomes for some classes of microscopic events, namely decoherent
measurements, but it is not completely arbitary. Rather, it makes very
precise predictions for the probabilities of those outcomes, and,
furthermore, the evolution of these probability distributions is completely
Either dualist input influences the choice of when decohering measurements
occur (as Stapp suggests), or it changes the probabiliities of different outcomes
(as Saunders et al also consider). In the first
case, the range of influence is extremely limited, and hardly plausible in a
dualist theory. In the second case, the dualist input change the probability
rules of quantum physics, in just the same way as dualist input would have to
change Newton's laws of motion if it were to influence classical systems.
We conclude therefore, with Saunders and Brecha, that it is very doubtful
that any dualist or divine input into the operation of the natural world
proceeds by exploiting the small residual indeterminism of quantum physics.
Dualist control in quantum physics is no easier than in classical physics. That
is, any influence of a dual degree must affect those properties of objects that
are also measured by physics.
The challenge, therefore, is to find a coherent theory which explains what,
how, when and why those physical properties are changed.
