 Since we invent mathematics in its entirety, we do not discover pre-existing mathematical objects or facts or that mathematical objects have certain properties, for “one cannot discover any connection between parts of mathematics or logic that was already there without one knowing” (PG 481). In examining mathematics as a purely human invention, Wittgenstein tries to determine what exactly we have invented and why exactly, in his opinion, we erroneously think that there are infinite mathematical extensions.
