 Unlike many or most philosophers of mathematics, Wittgenstein resists the ‘Yes’ answer that we discover truths about a mathematical calculus that come into existence the moment we invent the calculus (PR §141; PG 283, 466; LFM 139). Wittgenstein rejects the modal reification of possibility as actuality—that provability and constructibility are (actual) facts—by arguing that it is at the very least wrong-headed to say with the Platonist that because “a straight line can be drawn between any two points,… the line already exists even if no one has drawn it”—to say “[w]hat in the ordinary world we call a possibility is in the geometrical world a reality” (LFM 144; RFM I, §21). One might as well say, Wittgenstein suggests (PG 374), that “chess only had to be discovered, it was always there!”
