Abstract

Frege is highly valued as a logician by Russell and Wittgenstein, the latter nonetheless concludes in his Tractatus that one of Frege's central notions, the judgment stroke, is "logically quite meaningless". In order to see why Wittgenstein thinks so, we will investigate the 'indirect interpretation thesis', which says that Wittgenstein's interpretation of Frege was strongly influenced by the reading Russell gives of the Begriffsschrift in Principia Mathematica and Principles of Mathematics. This is done by analyzing the different conceptions of logic, focusing on the representations of judgment and assertion in Frege, Russell and the early Wittgenstein. Stong similarities can be found between the interpretations of Russell and Wittgenstein, this makes the indirect interpretation thesis plausible, although Russell's influence cannot be the only reason why Wittgenstein rejected the judgment stroke as a logical symbol.
