Please allow my incipid observation. Rather then invoke non- material monads, let us, for arguments sake, assume that thought is a neurochemical phenomena, and that without this neurochemical phenomena, there is no thought. Similarly, mathematics as a phenomena, doesn't exist without a human primate, writing on the soil with a stick, marking clay or wax tablets, ink on paper, or human fingers executing a computer program. All material, from beginning to end. Is there any evidence, of the existence of non- material things?

That's why there's been a discussion of whether mathematical objects exist. They certainly exist in the sense of there being proofs of existential formula, such as Ex(x=prime and x>2 and x<4). But I don't think satisfying an existential formula is existence in the physical sense.

I can't agree more.




Physical existence admits of ostensive definition - which mathematicians think of as not very definite.


Physical existence is about physical reality.

With comp, physical existence is about an internal view of a mathematical phenomenon occurring from arithmetic when seen from inside.

A collective dream, if you want. It would be an error to put physical existence as mathematical existence. It is more a psychological or theological existence.
