This entry introduces the Lockean Thesis and sketches the ways in which the lottery paradox, the preface paradox, and the problem of merely statistical evidence can be used to put pressure on the Lockean Thesis.

One recurrent objection to the idea that the right kind of reasons for or against an attitude are object-given reasons for or against that attitude is that object-given reasons for or against belief and disbelief are incapable of explaining certain features of epistemic normativity. Prohibitive balancing, the behaviour of bare statistical evidence, information about future or easily available evidence, pragmatic and moral encroachment, as well as higher-order defeaters, are all said to be inexplicable in terms of those object-given reasons. In (...) this paper, I provide a rebuttal to all these challenges by drawing attention to the object-given reasons for and against the third doxastic state, namely the suspension of judgement. First, I introduce an original picture of how suspension relates to belief and disbelief – as ways of being decided – which yields a novel weighing model of the corresponding reasons. Second, I demonstrate that this new take on doxastic deliberation can accommodate all five features of epistemic normativity. Finally, I extend the weighing model to cover practical deliberation and the suspension of intentions. The resulting theory provides an explanation of why epistemic and practical normativity differ in certain respects in terms of a significant difference between doxastic and conative suspension.

ABSTRACT Self-fulfilling beliefs are, in at least some cases, a kind of belief that is rational to form and hold in the absence of evidence. The rationality of such beliefs have significant implications for a range of debates in epistemology. Most startlingly, it undermines the idea that having sufficient evidence for the truth of is necessary for it to be rational to believe that. The rationality of self-fulfilling beliefs is here defended against the idea that their rationality is incompatible with (...) a compelling closure principle. (shrink)

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical disagreement’. Chapters 1 and (...) 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)
