Wittgenstein’s programme of a New Logic

Abstract

The young Wittgenstein called his conception of logic “New Logic” and opposed it to
the “Old Logic”, i.e. Frege’s and Russell’s systems of logic. In this paper the basic
objects of Wittgenstein’s conception of a New Logic are outlined in contrast to
classical logic. The detailed elaboration of Wittgenstein’s conception depends on the
realization of his ab-notation for first order logic.
