 Individually, the members of the Vienna Circle published extensively before, during and after the years of the Circle around Schlick. For some (Frank, Hahn, Menger, Neurath), philosophy was only part of their scientific output, with numerous monographs and articles in their respective disciplines (mathematics, physics and social science); others (Schlick, Carnap, Feigl, Waismann) concentrated on philosophy, but even their output cared relatively little for traditional concerns of the field. Here it must be noted that two early monographs by Schlick (1918/25) and Carnap (1928a), commonly associated with the Vienna Circle, mostly predate their authors’ participation there and exhibit a variety of influences not typically associated with logical positivism (see section 3.7 below). Moreover, important monographs by Frank (1932), Neurath (1931a), Carnap (1934/37) and Menger (1934) in the first half of the 1930s represent moves away from positions that had been held in the Circle before and contradict its orthodox profile. Yet the Circle’s orthodoxy, as it were, is not easily pinned down either. Schlick himself was critical of the manifesto of 1929 and gave a brief vision statement of his own in “The Turning Point in Philosophy” (1930). A long-planned book by Waismann of updates on Wittgenstein’s thought, to which Schlick was extremely sympathetic, was never completed as originally planned and only appeared posthumously (Waismann 1965; for earlier material see Baker 2003). Comparison with rough transcripts of the Circle’s discussions in the early 1930s (for transcripts from between December 1930 and July 1931 see Stadler 1997 [2015, 69–123]) suggest that Waismann’s Wittgensteinian “Theses”, dated to “around 1930” (Waismann 1967 [1979, Appendix B]), come closest to an elaboration of the orthodox Circle position at that time (but which remained not undisputed even then). Again, what needs to be stressed is that all of the Circle’s publications are to be understood as contributions to ongoing discussions among its members and associates.
