The paper explores the defence by the early sociologist of science Ludwik Fleck against the charge of relativism. It is shown that there are crucial and hitherto unnoticed similarities between Fleck’s strategy and the attempt by his contemporary Karl Mannheim to distinguish between an incoherent relativism and a consistent relationism. Both authors seek to revise epistemology fundamentally by reinterpreting the concept of objectivity in two ways: as inner- and inter-style objectivity. The argument for the latter concept shows the genuine political (...) background and intent of Fleck’s sociology of science and its ambition to relieve the cultural struggles of his time. (shrink)

In this paper, I show that there are important but hitherto unnoticed similarities between key figures of the Vienna Circle and early defenders of sociology of knowledge. The similarities regard their stance on potential implications of the study of science for political and societal issues. I argue that notably Otto Neurath and Karl Mannheim are concerned with proposing a genuine political philosophy of science that is remarkably different from today’s emerging interest in the relation between science and society in philosophy (...) of science.
