"In mathematical logic, one must distinguish between the ""axiomatic"" conception of logic, which was that of Frege, Russell, and Hilbert and a more ""pragmatic"" conception in terms of acts of proof, which is to be found in Gentzen's systems of natural deduction. Parallels are drawn between the conception of inference and logic in Wittgenstein's Tractatus Logico-Philosophicus and that of Gentzen. These parallels help us to throw new light on Wittgenstein's argument on ""following a rule""."; 1
