Carnap’s 1934 Objections to Wittgenstein’s Say/Show Distinction
- 178 Downloads
In sections 18 and 73 of Carnap’s Logical Syntax of Language, Carnap famously presents what he understands to be decisive objections to Wittgenstein’s Tractarian distinction between saying and showing. However, Carnap has been criticized in recent literature for severely misinterpreting that distinction. Against this criticism it is argued that Carnap reads that distinction as applying to two distinct classes of expressions (Unsinn and sinnlos) that he holds to emerge from his reading of Tractatus 4.1212 and related Tractarian theses. It is then argued that Carnap’s counterexamples to Wittgenstein’s theses are successful given his reading, and that our analysis of his counterexamples puts us in a unique position to reevaluate his conventionalism.
