Gettiered beliefs are those whose agents are subject to the kind of epistemologically significant luck illustrated by Gettier Cases. Provided that knowledge requires ungettiered belief, we can learn something about knowledge by figuring out how luck blocks it in Gettier Cases. After criticizing the most promising of the going approaches to gettiered belief—the Risk of False Belief Approach—, I explain and defend a new approach: the Risk of Misleading Dispositions Approach.Roughly, this view says that a belief is gettiered just in case its unfortunate subject has at best just luckily avoided being disposed by his belief’s actual grounds to believe a wide class of falsehoods about his environment. I then show how this approach undercuts an influential recent argument that knowledge has no more value than certain subsets of its components.

Luck looms large in numerous different philosophical subfields. Unfortunately, work focused exclusively on the nature of luck is in short supply on the contemporary analytic scene. In his highly impressive recent book Epistemic Luck, Duncan Pritchard helps rectify this neglect by presenting a partial account of luck that he uses to illuminate various ways luck can figure in cognition. In this paper, I critically evaluate both Pritchard’s account of luck and another account to which Pritchard’s discussion draws our attention—viz., that due to Nicholas Rescher. I also assess some novel analyses of luck that incorporate plausible elements of Pritchard’s and Rescher’s accounts.

In his (2004), Randolph Clarke assesses an important version of an influential argument against libertarianism about metaphysical freedom. Clarke calls the anti-libertarian argument he evaluates the Contrast Argument. It targets the following claim: there could be an undetermined free act done by S such that S would have freely done something else had S not done the act in question. This modal claim will be endorsed not only by proponents of main brands of libertarianism, but also by action theorists of other stripes – including many compatibilists. Clarke aims to defend the Contrast Argument from a prominent objection by developing a novel case for the premise under attack. I show that Clarke's attempted defense of the Contrast Argument fails, thereby protecting the relevant libertarian and compatibilist positions. In brief, Clarke's argument depends on an ambiguous principle, each available reading of which leaves some or other premise of his argument unjustified

Many philosophers hold that luck excludes control-more precisely, that an event is lucky for you only if that event lies beyond your control. Call this the Lack of Control Requirement (LCR) on luck. Jennifer Lackey [2008] has recently argued that there is no such requirement on luck. Should such an argument succeed, it would (among other things) disable a main objection to the "libertarian" position in the free will debate. After clarifying the LCR, I defend it against both Lackey's argument and a novel argument different in kind from Lackey's. I undermine each of these arguments by sketching a plausible error theory for its key intuition. For each argument, there's a natural reply available to its proponents. I show that these natural replies depend on certain mistaken general principles about luck. Neither Lackey's argument nor the novel argument I consider casts serious doubt on the LCR.

Two theses figure centrally in work on the epistemology of disagreement: Equal Weight (‘EW’) and Uniqueness (‘U’). According to EW, you should give precisely as much weight to the attitude of a disagreeing epistemic peer as you give to your own attitude. U has it that, for any given proposition and total body of evidence, some doxastic attitude is the one the evidence makes rational (justifies) toward that proposition. Although EW has received considerable discussion, the case for U has not been critically evaluated. Endorsing U, we argue, commits one to the highly controversial thesis that whatever fixes your rational attitudes can do so only by fixing what evidence you have. This commitment imposes a relatively demanding requirement on justified belief in U, one that we argue is not satisfied by what is currently the strongest available case for U, due to Roger White [2005]. Our challenge to U makes more trouble for its proponents than do the worries about U expressed by Gideon Rosen [2001] and Thomas Kelly [2010]. Moreover, if Kelly [2010] is correct in thinking that EW “carries with it a commitment to” U—a claim which we accept for reasons similar to Kelly’s but is beyond this paper’s scope (but see Ballantyne and Coffman [forthcoming])—then our challenge to U bears importantly on EW: to the extent that our challenge to U succeeds, EW also suffers

This paper has two main parts. In the first part, I argue that prominent moves in two related current debates in epistemology—viz., the debates over classical invariantism and the knowledge first movement—depend on one or the other of two claims about epistemic propriety: (1) Impropriety due to lack of a particular epistemic feature suffices for epistemic impropriety; and (2) Having justification to believe P suffices for having warrant to assert P. In the second part, I present and defend novel arguments against both claims.

In some of the most important recent work in religious epistemology, Paul Moser (2002, 2004, 2008) develops a multifaceted reply to a prominent attack on belief in God—what we’ll call the Hiddenness Argument. This paper raises a number of worries about Moser’s novel treatment of the Hiddenness Argument. After laying out the version of that argument Moser most explicitly engages, we explain the four main elements of Moser’s reply and argue that it stands or falls with two pieces in particular—what we call the Purposively Available Evidence Argument and the Cognitive Idolatry Argument. We then show that the Cognitive Idolatry Argument fails, leaving the Purposively Available Evidence Argument as Moser’s only potentially viable objection to the Hiddenness Argument. We conclude that Moser’s treatment of the Hiddenness Argument depends crucially on some controversial epistemological claims about certain of our moral beliefs, and is thus considerably more vulnerable than many have recognized.

Two theses are central to recent work on the epistemology of disagreement: Conciliationism:?In a revealed peer disagreement over P, each thinker should give at least some weight to her peer's attitude. Uniqueness:?For any given proposition and total body of evidence, the evidence fully justifies exactly one level of confidence in the proposition. 1This paper is the product of full and equal collaboration between its authors. Does Conciliationism commit one to Uniqueness? Thomas Kelly 2010 has argued that it does. After some scene-setting (?1), in ?2 we explain and criticize Kelly's argument, thereby defeating his larger argument that Conciliationism deserves no dialectical special treatment. But we argue further that Conciliationists are committed to a disjunction, one of whose disjuncts is Uniqueness, that amounts to an ?extremely strong and unobvious position? (??3?4). If we are correct, theorists should not treat Conciliationism as a default position in debates about the epistemic significance of disagreement

This paper advances the debate over the question whether false beliefs may nevertheless have warrant, the property that yields knowledge when conjoined with true belief. The paper’s first main part—which spans Sections 2–4—assesses the best argument for Warrant Infallibilism, the view that only true beliefs can have warrant. I show that this argument’s key premise conflicts with an extremely plausible claim about warrant. Sections 5–6 constitute the paper’s second main part. Section 5 presents an overlooked puzzle about warrant, and uses that puzzle to generate a new argument for Warrant Fallibilism, the view that false beliefs can have warrant. Section 6 evaluates this pro-Fallibilism argument, finding ultimately that it defeats itself in a surprising way. I conclude that neither Infallibilism nor Fallibilism should now constrain theorizing about warrant.
