There is an important assumption in this, however, that must be challenged; namely, that the brain is entirely spatial. There is a whole complex of assumptions bound up in the vocabulary being used, which still incorporates dualistic ways of thinking. ``Brain'' means something entirely ``physical'' (as opposed to ``mental'') and the ``physical'' is ``material'', and ``matter'' is located in space. Cartesian dualism is still rampant in the assumptions underlying all the language being used. I want now to suggest that there is a perfectly good place for the non-spatial in physics, and hence in the physics of the brain, so that there need be no contradiction -- despite their very different methodologies -- between the view of physics and the view of introspection. In fact, the only way of reconciling the physical and phenomenological views lies in a change of emphasis in our understanding of the physical world which makes the non-spatial primary.
Such a change is natural if one takes a quantum theoretic view. So I need to say more about what that implies. There are three basic approaches to quantum theory.
