There is no need for dualism, if we assume that mathematics is all there is, and that consciousness is a property of certain mathematical objects. "Never to see it whole" makes perfect sense, since why would a part be able to see the whole as a whole?

To put it another way, why do you infer a physical world, instead of a mathematical world, from your observations? Is there some reason why a pile of physical particles moving around in a certain pattern can cause a conscious experience, whereas that pattern as an abstract mathematical object can't be conscious?

What's the difference between these two? I think we are getting to the stage of philosophical abstraction where words lose all purchase. I have no idea what image "physical world, instead of a mathematical world" conjures up in Wei and Vladimir's minds, and the words "physical " and "mathematical" don't seem to help me.

My position is that "physical world" is meaningless, and the question was a rhetorical one that I asked because I thought Nesov was thinking in terms of a physical world.

I think it is reasonable to eliminate the phrase "physical world". "Hubble volume that we inhabit" seems to do most of the job that it did for me anyway.
