 Scholz and his followers adopted the scientific world view as advocated by the philosophers of the neo-positivistic movement, in particular of the Vienna Circle and the Berlin Society for Scientific Philosophy. However, contrary to this movement, he even applied the scientific world view to metaphysics. This was observed with reservations. Otto Neurath, e.g., mentioned Scholz and the Münster Group as having contributed much of value, but Scholz “represents nevertheless a full-blown metaphysics” (Neurath 1937, reprint Neurath 1981, pp. 804–805) which has to be rejected. The relation between Neurath and Scholz remained ambivalent. At least, they met at the First International Congress for Unity of Science at Paris in September 1935. The congress saw the establishment of a committee for the standardization of logical symbolism with members of the Vienna Circle, the Hilbert School, and the Münster Group. The initiative had come from Scholz and his school. The results of the committee’s negotiations were presented at the Forth International Congress for the Unity of Science at Cambridge (England) in July 1938 (cf. Peckhaus 2008, pp. 78–80; Behmann et al. 1937/38).
