    Yes, maybe you could say they’re parts of the same thing.  After all, “number” is an abstraction of a collection of physical objects, and I maintain that the laws of logic originate in the physical world.  That doesn’t mean that all logical statements refer to something physical – just that the logic is the logic of the physical world.

    Okay, but in math, which is a branch or subset of logic, there are such things as imaginary numbers, complex numbers, transcendental numbers and, of course, infinity.

    Explain how the physical world fits in, please.
