It is the finite construction, like a theory, which can be incomplete. The arithmetical reality is complete. The theories are incomplete. A model or a reality is complete. A person or a theory is incomplete with respect to what its studies, even limited to numbers. > The verb is "to abstract" meaning to leave aside irrelevant things.

With Mechanism, the physical universe is not emulable by any machine. But it can admit sequences of better and better approximation. With mechanism, the physical universe is a purely phenomenological constructs, made by *all* sound universal number in arithmetic, and indeed, they all gives the same physics, and we can compare it with Nature: just compare the math of the material modes with what we infer from observation. It is a waste of time to *speculate* that a theory is wrong, without evidences, when we have no alternate theories. I think.
