I review proposed skepticisms in recent literature (or skeptical invariantisms, if we understand skepticism semantically), contrast their basic commitments and highlight some of their comparative theoretical attractions and problems. To help set the scene for the discussion, I start with Unger’s (1975) modern classic of global skepticism about knowledge (and justification). I then distinguish three extant categories of skepticism in the recent literature: two non‐traditional and one more traditional. On the non‐traditional side are fallibilist science‐based skepticism (which relaxes thestringencyof the (...) standard of knowledge) and practical skepticism (which questions theintellectualcharacter of the standard of knowledge) and on the traditional side high‐standard/infallibilist. I then briefly present and discuss representatives of each category. (shrink)

I develop one partial explanation of the origins of our fallibilist intuitions about knowledge in ordinary language fallibilism and argue that this explanation indicates that our epistemic methodology should be more impartial and theory-neutral. First, I explain why the so-called Moorean constraint (cf. Hawthorne 2005, 111) that encapsulates fallibilist intuitions is fallibilism’s cornerstone. Second, I describe a pattern of fallibilist reasoning in light of the influential dual processing and heuristics and biases approach to cognition (cf. Kahneman 2011; Thaler and Sunstein (...) 2008; Evans 2017). I suggest that this pattern of reasoning involves the question-substitution heuristic, the availability and representativeness heuristics, the focusing bias as well as framing effects, priming and the anchoring and adjusting heuristic. Third, I argue that this fallibilist pattern of reasoning is methodologically dubious because it involves a vicious circularity and briefly outline an alternative, more impartial and theory-neutral abductive methodology for the theory of knowledge. Finally, I briefly explain how this analysis sheds light on the ordinary language fallibilism of Moore (1939), Austin (1961), Wittgenstein (1969) and Chisholm (1982). (shrink)

Skeptical invariantism does not account for the intuitive connections between knowledge, assertion, and practical reasoning and this constitutes a significant problem for the position because it does not save corresponding epistemic appearances (cf. Hawthorne (2004:131-5)). Moreover, it is an attraction of fallibilist over infallibilist-skeptical views that they can easily account for the epistemic appearances about the connections between knowledge, assertion, and practical reasoning (cf. Williamson (2000:249-255)). Call this argument ‘the argument from the knowledge norm’. I motivate and develop a Humean, (...) pragmatist strategy for a skeptical response to ‘the argument from the knowledge norm’. Afterwards I outline a ‘toy’ version of pragmatic skepticism that can implement the strategy and save our everyday practice of assertion and practical reasoning. To this effect, I distinguish between assertibility conditions and truth conditions for ‘know’ and suggest that while assertibility conditions are pragmatic conditions sensitive to practical exigencies, truth conditions are semantic conditions sensitive only to truth. I briefly respond to three objections and conclude that pragmatic skepticism is resourceful enough to save our everyday practice of (fallibilist) assertion and practical reasoning and, hence, pay some due respect to corresponding epistemic appearances.

AbstarctIn the first installment of Varieties of Skeptical Invariantism, we set the scene for subsequent discussion with Unger's (1975) modern classic of global skepticism and distinguished three varieties of skeptical invariantism in recent literature: traditional skeptical invariantism, fallibilist science-based skepticism and practical skepticism. We then presented fallibilist science-based skepticism, that is, the position that relaxes the stringency of the standard of knowledge but still questions parts of our everyday knowledge on the basis of scientific reasons. In particular, we presented Frances’ (...) (2005) ‘live’ skepticism and Hannon's (forthcoming) ‘hard-hitting’ skepticism. In this second installment, we present the two other varieties of skeptical invariantism we identified: traditional skepticism (high-standard and infallibilist) that respects all three commitments (intellectualism, invariantism, stringency) and practical skepticism that questions the intellectualist commitment.

Some recent epistemologists propose that certainty is the norm of action and assertion. This proposal is subject to skeptical worries. If, as is usually supposed, certainty is very hard to come by, legitimate action and assertion will be rare. To remedy this, some have conjoined their certainty-norms with a context-sensitive semantics for ‘certainty’. For a proposition to be certain for you, you only need to be able to exclude relevant alternatives. I argue that, depending on what makes an alternative relevant, (...) this kind of view is disingenuous. In particular, if an alternative can be made relevant by being relevant to rational action, it allows an escape from the skeptical consequences only by licensing David Lewis-style utterances of the form, “You know that p only if there is no probability, no matter how small, that not-p—Psst!—Unless that probability is really small.” While there are legitimate ways to exclude some possibilities from relevance, it is disingenuous, I argue, to exclude possibilities from relevance on the basis of the very characteristic—low but nonzero probability—that is claimed to be incompatible with certainty.
