A number of philosophers have recently proposed several alleged cases of “knowledge from falsehood,” i.e., cases of inferential knowledge epistemised by an inference with a false crucial premise. This paper examines such cases and argues against interpreting them as cases of knowledge from falsehood. Specifically, I argue that the inferences in play in such cases are in no position to epistemise their conclusions.

Several authors have recently argued against intellectualism, the view that one’s epistemic position with respect to p depends exclusively on one’s truth-relevant factors with respect to p. In this paper, I first examine two prominent arguments for the anti-intellectualist position and find both of them wanting. More precisely, I argue that these arguments, by themselves, are underdetermined between intellectualism and anti-intellectualism. I then manifest the intuitive plausibility of intellectualism by examining the ordinary conversational pattern of challenging a claim.

To resolve the lottery paradox, the “no-justification account” proposes that one is not justified in believing that one's lottery ticket is a loser. The no-justification account commits to what I call “the Harman-style skepticism”. In reply, proponents of the no-justification account typically downplay the Harman-style skepticism. In this paper, I argue that the no-justification reply to the Harman-style skepticism is untenable. Moreover, I argue that the no-justification account is epistemically ad hoc. My arguments are based on a rather surprising finding (...) that the no-justification account implies that people living in Taiwan typically suffer from the Harman-style skepticism. (shrink)

It is widely accepted that our initial intuitions regarding knowledge attributions in stakes-shifting cases (e.g., Cohen’s Airport) are best explained by standards variantism, the view that the standards for knowledge may vary with contexts in an epistemically interesting way. Against standards variantism, I argue that no prominent account of the standards for knowledge can explain our intuitions regarding stakes-shifting cases. I argue that the only way to preserve our initial intuitions regarding such cases is to endorse position variantism, the view (...) that one’s epistemic position may vary with contexts in an epistemically interesting way. Some had argued that epistemic position is incompatible with intellectualism. In reply, I point out that position variantism and intellectualism are compatible, if one’s truth-relevant factors with respect to p can vary with contexts in an epistemically interesting way.

Some cases show that counterfactual conditionals (‘counterfactuals’ for short) are inherently ambiguous, equivocating between forward-tracking and backtracking counterfactu- als. Elsewhere, I have proposed a causal modeling semantics, which takes this phenomenon to be generated by two kinds of causal manipulations. (Lee 2015; Lee 2016) In an important paper (Hiddleston 2005), Eric Hiddleston offers a different causal modeling semantics, which he claims to be able to explain away the inherent ambiguity of counterfactuals. In this paper, I discuss these two semantic treatments (...) and argue that my (bifurcated) semantics is theoretically more promising than Hiddleston’s (unified) semantics. (shrink)

Recent literature has seen a surging interest in the modal principle involved in the Gettier-style thought experiments. According to the necessitation thesis, the modal principle underlying the Gettier-style thought experiments takes the form of a principle of necessitation. It is widely agreed that the necessitation thesis is seriously threatened by the problem of deviant realizations. Based on the Gricean pragmatic theory of communication, I defend the necessitation thesis against the problem of deviant realizations. The present account bears some significant similarities (...) to Pierre Saint-Germier’s account. After comparing and contrasting these two accounts, I argue that the differences between them actually speak in favor of the present account over Saint-Germier’s one. (shrink)

Reasons evidentialism is the view that normative reasons can be analyzed in terms of evidence about oughts (i.e., propositions concerning whether or not S ought to phi). In this paper, I defend a new reason-evidentialist account according to which normative reasons are evidence against propositions of the form S ought not to phi. The arguments for my view have two strands. First of all, I argue that my view can account for three difficulty cases, cases where (i) a fact is (...) both a reason for S to phi and a reason for S not to phi, (ii) a fact is both evidence for the proposition that S ought to phi and evidence for the proposition that S ought not to phi, and (iii) the subject is genuinely torn, as far as reasons are concerned, between phi-ing and not phi-ing. Second, I argue that my view can account for what a reason against S phi-ing is. (shrink)

The stakes-shifting cases suggest that pragmatic factors such as stakes play an important role in determining our intuitive judgments of whether or not S knows that p. This seems to be in conflict with intellectualism, according to which pragmatic factors in general should not be taken into account, when considering whether or not S knows that p. This paper develops a theory of judgments of knowledge status that reconciles intellectualism with our intuitive judgments regarding the stakes-shifting cases. I argue that (...) pragmatic factors affect only our epistemic perspectives, i.e., the ways in which we evaluate S’s epistemic position. Therefore, pragmatic factors only have an indirect impact on our judgments of knowledge status. (shrink)

In this paper, I defend the thesis that knowledge is the norm of assertion. I first examine three prominent “counterexamples”: false assertion, selfless assertion, and assertion based on mere justified true belief. I argue that they all fail to square well with our ordinary intuitions. However, the contemporary debate over the norm of assertion depends heavily on the method of counterexamples, whose crux is to prompt our intuitions regarding the appropriateness (or inappropriateness) of a certain kind of assertions. This method (...) has its limits as sometimes the debate simply boils down to a clash of intuitions. I think we can do better. In the second part of the paper, I construct a positive argument for the knowledge norm, showing that the knowledge norm can be derived from the general account of the conversational role of assertion. I argue that in order for assertion to play the role it plays in conversation, the knowledge norm must hold. (shrink)
