 Whatever the details, their non-cognitivism supports the idea that the left wing’s anti-metaphysics was primarily deflationist. They opposed all claims to have a categorically deeper insight into reality than either empirical or formal science, such that philosophy would stand in judgement of these sciences as to their reality content or that mere science would stand in need of philosophical interpretations. (Concerned with practical problems, they likewise opposed philosophical claims to stand above the contestations of mere mortals.) Importantly, such deflationism need not remain general and vague, but can be given precise content. For instance, it has been argued (Carus 1999) that Carnap was correct to understand Tarski’s theory of truth not as a traditional correspondence theory such that truth consisted in some kind of agreement of statements or judgements and facts or the world where the latter make true the former. In Carnap’s unchanged opposition to the classical correspondence theory of truth in turn lies not only the continuity between his own syntactic and semantic phases, but also the key to his and the entire left Vienna Circle’s understanding of their anti-metaphysical campaign. (On various occasions in the early 30s, Hahn, Frank and Neurath opposed correspondence truth very explicitly, while, in later years, Neurath resisted Tarskian semantics precisely because he wrongly suspected it of resurrecting correspondentism and Frank continued to castigate correspondentism whenever required. On this tangled issue, see Mormann 1999, Uebel 2004, Mancosu 2008.)
