Discovered Math Isn't Synonymous With Platonism (Score 1)

Math is discovered; clearly, it's not invented because 2 + 2 != 5 and any attempt to make 2 + 2 = 5 would simply devolve renaming 4 under a different name.

Having said that, the counter argument against 'math is discovery' (which is that, if math is discovery, then it must be Platonic, but Platonism is bullshit, so math is not discovery) is that nothing points towards 'math is platonic' more so than other theories, like 'math is a set of ideas that we must inevitably reason towards'(the nomological view)

Note that the 'everyone knows math' argument doesn't support Platonism; anything that is even meaningful is shareable. (yes, even 'internal' emotions)
