"Towards the end of his life Neurath referred to the ‘mosaic of the sciences’. In the spirit of this formulation we can arrive at an understanding of his life’s work by means of a kind of collage, employing the regulative idea of the unity of science and society."

"Many innovations of current history and philosophy of science were, in fact, anticipated in Neurath’s oeuvre. The rediscovery of Neurath was therefore not merely a phenomenon of academic nostalgia, but itself constitutes research into the conditions and possibilities of changing a paradigm in the philosophy of science."

"“What is the Vienna Circle?” is a question which is neither rhetorical nor trivial. It is perhaps an attempt to ‘square the circle’ – which is, meanwhile, mathematically possible, as Karl Menger described as early as 1934."

"The new historiography on Logical Empiricism sets in with the rediscovery of Ernst Mach (1838-1916) as a precursor of Gestalt theory, evolutionary epistemology, (possibly radical) constructivism and the modern historically oriented philosophy of science. But already in Mach’s reception of the Vienna Circle one can see not only a certain pluralism of views but also a polarization of the various positions (Mach’s influence on Carnap’s Aufbau / Logical Construction, the critical distancing to “psychologism” in the manifesto, the alternative to the principle of economy in Karl Menger, etc.) Nevertheless, this research program, which was interpreted differently by the Vienna Circle, actually represented a sort of prototype for Logical Empiricism in the interwar years – irrespective of whether one backs the bold claim as to the existence of a “typical Austrian philosophy” (as opposed to German idealism)."

"The history of the development of Logical Empiricist theories since the turn of the century does not allow any clear canonization of a philosophical school in the strict sense, since what we are dealing with is a dynamic between center and periphery. The varying receptions of Wittgenstein, Tarski and Popper have influenced the development of various philosophies of science inspired by rational reconstruction, on the one hand, and by encyclopedic models on the other."
