6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / b. Against mathematical platonism

2521	'Real' maths objects have no causal role, no determinate reference, and no abstract/concrete distinction [Katz]
	Full Idea: Three objections to realism in philosophy of mathematics: mathematical objects have no space/time location, and so no causal role; that such objects are determinate, but reference to numbers aren't; and that there is no abstract/concrete distinction.
	From: Jerrold J. Katz (Realistic Rationalism [2000], Int.xxix)
