> That which is not a part of base reality. If base reality were operating using the same rules as Conway's game of life then cells would be real, but gliders would be made up. Since Conway's game of life actually runs in a simulation on some computer or another, cells are also made up.
So in your view, anything that is a composite of two or more primitives is by definition "made up".
Therefore, given a standard definition of natural numbers [1], any number except zero is made up?
> Newton's equations are now accepted as an approximation; they are not isomorphic to part of the structure of the noumenon
They are actually, within the domain for which they are valid. General relativity reduces to Newton's equations in the right context.
