This paper argues that the proponents of epistemological scientism must take some stand on scientific methodology. The supporters of scientism cannot simply defer to the social organisation of science because the social processes themselves must meet some methodological criteria. Among such criteria is epistemic evaluability, which demands intersubjective access to reasons. We derive twelve theses outlining some implications of epistemic evaluability. Evaluability can support weak and broad variants of epistemological scientism, which state that sciences, broadly construed, are the best sources (...) of knowledge or some other epistemic goods. Since humanities and social sciences produce epistemically evaluable results, narrow types of scientism that take only natural sciences as sources of knowledge require additional argumentation in their support. Strong scientism, which takes sciences as the only source of knowledge, also needs to appeal to some further principles since evaluability is not an all-or-nothing affair. (shrink)

This paper argues that the main global critiques of scientism lose their punch because they rely on an uncharitable definition of their target. It focuses on epistemological scientism and divides it into four categories in terms of how strong (science is the only source of knowledge) or weak (science is the best source of knowledge) and how narrow (only natural sciences) or broad (all sciences or at least not only the natural sciences) they are. Two central arguments against scientism, the (...) (false) dilemma and self‐referential incoherence, are analysed. Of the four types of epistemological scientism, three can deal with these counterarguments by utilizing two methodological principles: epistemic evaluability of reliability and epistemic opportunism. One hopes that these considerations will steer the discussion on scientism to more fruitful pastures in the future. For example, there are interesting methodological considerations concerning what evaluability or reliability and epistemic opportunism entail. (shrink)

In this chapter we examine Moti Mizrahi’s claim that philosophers’ opposition of scientism is founded on their worry that scientism poses “a threat to the soul or essence of philosophy as an a priori discipline”. We find Mizrahi’s methodology for testing this thesis wanting. We offer an alternative hypothesis for the increased resistance of scientism: the antipathy started as a reaction to the New Atheist movement. We also consider two varieties of weak scientism, narrow and broad, and argue that narrow (...) versions of scientism draw unnatural and unfounded distinctions within science. Mizrahi belongs somewhere between these two types, but he commits the same mistakes as proponents of the narrow variety. We demonstrate that Mizrahi’s defence of weak scientism is problematic, once again, due to methodological reasons. As an alternative, we propose that weak scientism should be based on epistemic opportunism. Epistemic opportunism explains the success of science with scientists’ willingness to adopt any methods that demonstrably work. We also show how opportunistic scientism can avoid charges of triviality. (shrink)
