 Considering the Vienna Circle as a whole in the light of this reading of its anti-metaphysical philosophy, we find the most striking division within it yet. Unlike Carnap and the left wing, Schlick had little problem with a correspondence theory of truth once it was cleansed of psychologistic and intuitive accretions and centered on the idea of unique coordination of statement and fact. In this lay the strongest sense of continuity between his pre-Vienna Circle General Theory of Knowledge (1918/25) and his post-Tractarian epistemology (1935a, 1935b). (Schlick also showed little enthusiasm for the constructivist tendencies which already the manifesto of 1929 had celebrated.) Allowing for some simplification, it must be noted that Schlick’s attack on metaphysics (which gradually weakened anyway) presupposed a non-constructivist reading of the criterion of significance. Whether his conception can escape the charge self-refutation must be left open here.
