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)

In many ways one’s quest for knowledge can go wrong. Since the publication ofAmélie Rorty’s article “Akratic Believers”, in 1983, there has been a great deal of discussion asto one particular form of flaw in reasoning to which we, as less-than-perfect rational entities,are continuously prone to in our epistemic endeavors: “epistemicakrasia”. The debate that article gave rise became, then, split between authors to whom the ideaof epistemicakrasiapromotes an interesting diagnosis of some of our intellectual imperfec-tions, and their opponents, those who (...) disclaim the very possibility of the phenomenon. Inthis paper I’ll examine, and present original objections to, four of the main arguments put for-ward by the latter, showing that none of them have consistently ruled out all the legitimatelyconceivable forms of the phenomenon.

It seems that epistemically rational agents should avoid incoherent combinations of beliefs and should respond correctly to their epistemic reasons. However, some situations seem to indicate that such requirements cannot be simultaneously satisfied. In such contexts, assuming that there is no unsolvable dilemma of epistemic rationality, either (i) it could be rational that one’s higher-order attitudes do not align with one’s first-order attitudes or (ii) requirements such as responding correctly to epistemic reasons that agents have are not genuine rationality requirements. (...) This result doesn’t square well with plausible theoretical assumptions concerning epistemic rationality. So, how do we solve this puzzle? In this paper, I will suggest that an agent can always reason from infallible higher-order reasons. This provides a partial solution to the above puzzle. (shrink)

There is a view in the literature around beliefs that evidence responsiveness is a necessary feature of beliefs. The reasoning is that because beliefs are governed by truth they must be evidence responsive. A mental state that fails to be evidence responsive, therefore, could not be a belief as it could not be governed by truth. The implication is that even those evidence-resistant mental states that appear to be beliefs are in fact something else. I argue that evidence resistance is (...) a feature of at least some beliefs, so evidence responsiveness cannot be a necessary feature of belief. (shrink)

There is widespread disagreement about whether epistemic akrasia is possible. This paper argues that the possibility of epistemic akrasia follows from a traditional rationalist conception of epistemic critical reasoning, together with considerations about the fallibility of our capacities for reasoning. In addition to defending the view that epistemic akrasia is possible, we aim to shed light on why it is possible. By focusing on critical epistemic reasoning, we show how traditional rationalist assumptions about our core cognitive capacities help to explain (...) the possibility of epistemic akrasia. (shrink)

_ Source: _Page Count 19 Epistemic akrasia refers to the possibility of forming an attitude that fails to conform to one’s best judgment. In this paper, I will be concerned with the question whether epistemic akrasia is rational and I will argue that it is not. Addressing this question, in turn, raises the question of the epistemic significance of higher-order evidence. After examining some of the views on this subject, I will present an argument to show why higher-order evidence is (...) relevant to the epistemic status of the pertinent first-order beliefs. This helps to show why a standard argument for the rationality of epistemic akrasia does not work. Finally, I shall try to show how considerations involving Davidson’s theory of radical interpretation bear on the question of the rationality of epistemic akrasia. (shrink)

In this work, I argue for the possibility of epistemic akrasia. An individual S is epistemically akratic if the following conditions hold: S knowingly believes that P though she judges that it is epistemically wrong to do so and Having these mental states displays a failure of rationality that is analogous to classic akrasia. I propose two different types of epistemic akrasia involving different kinds of evidence on which the subject bases her evaluation of her akratic belief. I examine three (...) objections to their possibility. I suggest that the key to defending the possibility of epistemic akrasia is to explain condition. I finally argue that epistemic akrasia is possible, and that it represents a failure of mental agency. (shrink)
