>>16708335I mean, I'm OP and am, in fact, arguing for Platonism without calling it Platonism.
"Math" is an abstraction of an underlying reality, yes. The point is that reality is not purely material.
Constraints on material imply forces (or rules, or laws, or forms, what have you) "above" or "beyond" the material. Or else "it just does that" and we can never define what "does" is.
The universe is mathematical insofar as math describes it. The universe is also "colorful" insofar as color "describes" it.
