> Did Calculus exist in 3 B.C.? > Math has always existed. It still exists to this day. > Math is discovered. I really disagree with Platonism; I had trouble explaining why I had such a visceral reaction against it until I read "The Reasonable Ineffectiveness of Mathematics"[1], which largely frames the Platonist/Non-Platonist debate as a difference in culture among engineers, mathematicians, and physicists. Of course you're right about the other examples - I think it's pretty uncontroversial to say that there's no crazy dualism / "Does a tree falling in the woods without anyone to hear it still make a sound?" thing going on.
