The reader may be puzzled that I should be writing a book which encompasses both [consciousness and quantum mechanics], since they are not usually thought to have much connection with each other. But it seems to me clear that they do […]. First, in reflecting on the relation of consciousness to the matter of the brain, philosophers have been apt to take matter for granted, assuming that it is mind rather than matter that is philosophically problematic. This has much to do with the fact that they tend to think of matter along essentially Newtonian lines. The Newtonian conception of matter is incorrect, however, and it is high time that philosophers began properly to take on board the conception that has replaced it. Quantum mechanics just is the theory of matter, as currently conceived. So it is with the matter of Schrödinger, Heisenberg and Dirac that mind has to be brought to terms, not the reassuringly solid stuff of Galileo, Descartes and Newton. This matter, the matter of quantum mechanics, is deeply problematic, and philosophically ill-understood.
Most philosophers who have tackled the mind-body problem have, as I say, tended to regard matter as having a conceptual solidity to match its supposed literal solidity; they have regarded it as a constant, so to speak, in the metaphysical equation. So the mind-body problem itself has, by most contemporary philosophers, been seen as a calling for mind to be accommodated to the material world – all the ‘give’ being on the side of mind. Some wonderfully Procrustean devices have been invoked to that end; so-called eliminative materialism and behaviourism […] being extreme examples. This prejudice in favour of the material seems to me devoid of any sound scientific foundation. Quantum mechanics has robbed matter of its conceptual quite as much as its literal solidity. Mind and matter are alike in being profoundly mysterious, philosophically speaking. And what the mind-body problem calls for, almost certainly, is a mutual accommodation: one which involves conceptual adjustments on both sides of the mind-body divide.
