Doesn't it depend what you mean by 'live'? As far as I can see, I live in a definite world, but I am aware of having an imagination and a bunch of concepts about life (same thing?) Since I observe my imagination I can say it is also definite, though what it purports to reference is not observed and therefore is not definite. Linking this with another current thread, if you have a QM-realistic view of life, can you hold to a materialist view of consciousness?

I have the impression that on this list "materialist" has come be an epithet. It is applied to physicists who think the world consists of a ray in an infinite dimensional complex Hilbert space - which is about as "material" as Bruno's modal logic. Apparently anything that is well defined and makes definite predictions is "material".


To say that world is a big ray is still physicalism, but also non materialism as the physical reality become mathematical. But materialist will add that the Hillbert ray is just a too to descrive the bahavior of some primary matter.

The computationalist, post-UDA if I can say, will not favor physicalist, neither in its materialist or mathemlaticalist form. He asks for a justification of that Hilbert ray from elementary arithmetic/computer science only.
