Anyway, I picked up a small book on "Quantum Mechanics and the Participating Observer" called Mindful Universe. The race is on to see if I can finish it in three weeks and remind myself to return it on time. In the meantime, it's quite a read, and provides quite a support against materialist critics of the mind-body dichotomy of early Buddhism:
According to orthodox (von Neumann) quantum theory, achievement of a satisfactory reduction of the smeared out brain state to a brain state coordinated with the subject's streams of conscious experiences is achieved through the entry of a process 1 intervention, [a probing action] which selects from the smear of potentialities generated by the mechanical process 2 evolution a particular way of separating the physical state into a collection of components, each corresponding to some definite experience. The form of such an intervention is not determined by the quantum analog (process 2) of the physically deterministic continuous dynamical process of classical physics: some other kind of input is needed.
The choice involved in such an intervention seems to us to be influenced by consciously felt evaluations, and there is no rational reason why these conscious realities, which certainly are realities, cannot have the sort of effect that they seem to have.
