  In sum, it is not clear how the distinction between categorematic and syncategorematic terms, so natural in the framework of a term logic, can be extended to a post-Fregean function/argument conception of propositional structure. At any rate, none of the natural ways of extending the distinction seem apt for the demarcation of the logical constants. Carnap concedes that the distinction between categorematic and syncategorematic expressions “seems more or less a matter of convention” (1947, 6–7). However, the idea that logical constants are syncategoremata does not wither away entirely with the demise of term logics. Its influence can still be felt in Wittgenstein’s insistence that the logical constants are like punctuation marks (1922, §5.4611),[3]  in Russell’s claim that logical constants indicate logical form and not propositional constituents (1992, 98; 1920, 199), and in the idea (found in Quine and Dummett) that the logical constants of a language can be identified with its grammatical particles.
