ABSTRACT This book symposium features three critical pieces dealing with Duncan Pritchard's book, 'Epistemic Angst'; the symposium also contains Pritchard's replies to his critics.

O slogan "Conhecimento gera dogmatismo" causa-nos imediata perplexidade. O dogmatismo é trivialmente tomado como uma postura irracional de manutenção de crenças. Saul Kripke, contra esta intuitiva perspectiva, ofereceu um argumento que supostamente prova que se você sabe que uma proposição P é verdadeira, então você está autorizado a ser dogmático quanto a se P. Neste ensaio, temos os seguintes objetivos. Em primeiro lugar, vamos criticar uma recente objeção ao argumento pró-dogmatismo de Kripke feita por Rodrigo Borges, segundo a qual, uma (...) suposição sobre meta-conhecimento deve ser assumida por Kripke a fim de que seu argumento seja defensável. Em segundo lugar, vamos propor uma outra crítica ao argumento de Kripke, segundo a qual uma de suas premissas assume uma perigosa dose de voluntarismo doxástico, o que compromete irremediavelmente o seu argumento. Concluiremos que embora o argumento de Kripke possa ser defendido de certas críticas, a sua conclusão paradoxical é injustificada. (shrink)

The standard conception of misleading evidence has it that e is misleading evidence that p iff e is evidence that p and p is false. I argue that this conception yields incorrect verdicts when we consider what it is for evidence to be misleading with respect to questions like whether p. Instead, we should adopt a conception of misleading evidence according to which e is misleading with respect to a question only if e is in-fact irrelevant to that question – (...) a relation that requires that e fail to be both explanatorily connected to and evidence for any truth that answers the question. This modified conception allows e to be non-misleading evidence with respect to a question even if e is evidence for the false answer to that question. It also points toward a new argument for and explanation of the truth of a central premise – what Maria Lasonen-Aarnio dubs “Entitlement” – that generates the infamous dogmatism puzzle. (shrink)

Half a century later, a Dretskean stance on epistemic closure remains a minority view. Why? Mainly because critics have successfully poked holes in the epistemologies on which closure fails. However, none of the familiar pro-closure moves works against the counterexamples on display here. It is argued that these counterexamples pose the following dilemma: either accept that epistemic closure principles are false, and steal the thunder from those who attack classical logic on the basis of similarly problematic cases—specifically, relevance logicians and (...) like-minded philosophers—or stick with closure and surrender to relevantist claims of failure in truth-preservation aimed at classical rules of inference. Classicist closure advocates find the promise of a way out of the dilemma in the works of Roy Sorensen and John Hawthorne. The paper argues against their pro-closure move and renews Robert Audi’s call for a theory of closure-failure. (shrink)

The paper introduces a new problem for fallibilist and infallibilist epistemologies – the diachronic threshold problem. As the name suggests, this is a problem similar to the well–known threshold problem for fallibilism. The new problem affects both fallibilism and infallibilism, however. The paper argues that anyone who worries about the well known problem for fallibilism should also worry about this new, diachronic version of the problem.

According to the dogmatist, knowing p makes it rational to disregard future evidence against p. The standard response to the dogmatist holds that knowledge is defeasible: acquiring evidence against something you know undermines your knowledge. However, this response leaves a residual puzzle, according to which knowledge makes it rational to intend to disregard future counterevidence. I argue that we can resolve this residual puzzle by turning to an unlikely source: Kavka’s toxin puzzle. One lesson of the toxin puzzle is that (...) it is irrational to intend to do that which you know will be irrational. This yields a simple reply to the dogmatist: it is irrational to intend to disregard future evidence because you can know in advance that it will be irrational to do so. (shrink)
