I examine the thesis that Otto Neurath anticipated the programme of naturalised epistemology already at the time of the Vienna Circle and consider the relation between Neurath's proposals and those of two contemporary theorists whose research programmes he would thus have broadly anticipated. The thesis is confirmed by reference to Neurath's own writings. The connection between Neurath's programme and the programmes of his two successors considered here, however, is found to be highly indirect in one case and nonexistent in the (...) other — despite their undeniable overlap.

It is not well known that Moritz Schlick, whose name is inseparable from the development of logical positivism, was extremely critical of positivism prior to the 1920’s. The positivism Schlick found fault with was associated with the physicist Ernst Mach. Schlick went to considerable lengths to criticize Machian positivism on both epistemological and ontological grounds. He also objected to the positivist claim to be able to account for relativity theory within its framework.Schlick’s views before his move to Vienna in 1922 (...) have been labeled a “critical empiricist realism” (see Feigl 1938, p. xx) or a “structural realism” (Friedman 1983, p. 501). His exposure to the work of Ludwig Wittgenstein is generally held up as the crucial factor in turning him away from his early realist views towards positivism. There is general acknowledgment of a major change in Schlick’s philosophical thinking in the early 20’s; disagreement exists, however, over both the extent of the change and whether it was a positive or negative one.

Yleensä Wienin piirin loogista empirismiä kannattaneet filosofit mielletään antirealisteiksi. Tässä artikkelissa kuitenkin argumentoidaan, että piirin johtohahmo Moritz Schlick oli eräänlainen realisti myös nykystandardien valossa. Näin ollen – niin yllättävältä kuin se kuulostaakin – positivismi ja realismi ovat yhteensovitettavissa. Schlick tosin erotti kannattamansa empiirisen realismin jyrkästi metafyysisestä realismista, jota hän piti merkityksettömänä. Schlickin realismin esittelyn lisäksi artikkelissa tarkastellaan yleisellä tasolla hänen epistemologiaansa, kielifilosofiaansa ja metafysiikan kritiikkiään. Tekstissä pohditaan myös Schlickin suosiman realismin asemaa ja relevanssia nykyisessä realismikeskustelussa.
