This paper discusses Sosa’s via media between existential relativism and absolutism. We discuss three implications of Sosa’s account which require some further clarification. First, we distinguish three alternative readings of Sosa’s account – the indexicalist, the homonymist and the (proper) relativist reading – and argue that they differ with respect to two crucial points: (a) they lead to different analyses of the lack of disagreement in existential discourse, and (b) they differ with respect to the question of whether conceptual schemes pick out different senses of “exist” or whether they pick out different entities to exist. Second, we ask Sosa to answer on four problematic implications of his final position: (a) Sosa appears to change the topic from ontology to semantics without solving the ontological issue. (b) It is puzzling why Sosa finally accepts the initially implausible explosion of reality. (c) Sosa is forced to accept that disputants really disagree in existential disputes (although faultlessly). (d) We offer an even simpler alternative option to reconcile the realist and the relativist intuitions by clarifying what is meant by “conceptual relativism”, without arguing for existential relativity at all. Third, we argue that Sosa’s argumentative reliance on an appropriate development of conceptual schemes drives him not only to a position of pure conceptual absolutism, but even to a more traditional form of ontological absolutism according to which nature itself manages to cut the cookies. In contrast to his apparent intention, this discharges Sosa’s via media from any relativist intuition.

In this paper I argue that a moderate form of epistemic relativism that is inspired by the work of Thomas Kuhn fails. First of all, it is shown that there is evidence to the effect that Kuhn already in his 'The Structure of Scientific Revolutions' proposes moderate relativism. Second, it is argued that moderate relativism is confronted with a severe dilemma that follows from Kuhn’s own argument for his relativistic conclusion. By focusing on the work of moderate relativists like Bernd Schofer and Gerald Doppelt this dilemma as well as the ultimate failure of Kuhn’s moderate relativism are exhibited.

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
