| Popis: | We re-examine the old question to what extent mathematics may be compared to a game. Under the spell of Wittgenstein, we propose that the more refined object of comparison is a "motley of language games", the nature of which was (implicitly) clarified by Hilbert: via different language games, axiomatization lies at the basis of both the rigour and the applicability of mathematics. In the "formalist" game, mathematics resembles chess via a clear conceptual dictionary. Accepting this resemblance: like positions in chess, mathematical sentences cannot be true or false; true statements in mathematics are about sentences, namely that they are theorems (if they are). In principle, the certainty of mathematics resides in proofs, but to this end, in practice these must be "surveyable". Hilbert and Wittgenstein proposed almost oppositie criteria for surveyability; we try to overcome their difference by invoking computer-verified proofs. The "applied"' language game is based on Hilbert's axiomatization program for physics (and other scientific disciplines), refined by Wittgenstein's idea that theorems are yardsticks to which empirical phenomena may be compared, and further improved by invoking elements of van Fraassen's constructive empiricism. From this perspective, in an appendix we also briefly review the varying roles and structures of axioms, definitions, and proofs in mathematics. Our view is not meant as a philosophy of mathematics by itself, but as a coat rack analogous to category theory, onto which various (traditional and new) philosophies of mathematics (such as formalism, intuitionism, structuralism, deductivism, and the philosophy of mathematical practice) may be attached and may even peacefully support each other.
