 As noted above, another innovation of Logical Syntax is the Principle of Tolerance. While it reflects a long-standing attitude on Carnap’s part, the principle itself is new. Later Carnap was to say that the Principle of Tolerance was “perhaps better called the principle of conventionality” (Carnap 1942, 247), that is, the conventionality of linguistic forms. Tolerance stabilizes the verification principle as well as Carnap’s empiricism, and it reinforces the idea that the analytic-synthetic distinction is always relative to a particular language (Creath 2009).
