To avoid the problem of regress, externalists have put forward defeaters-based accounts of justification. The paper argues that existing proposals face two serious concerns: (i) They fail to accommodate related counterexamples such as Norman the clairvoyant, and, more worryingly, (ii) they fail to explain how one can be epistemically responsible in holding basic beliefs—i.e., they fail to explain how basic beliefs can avoid being arbitrary from the agent’s point of view. To solve both of these problems, a new, externalist, defeaters-based (...) account of justification is offered—viz., System Reliabilism. The core message of the view—and the way it deals with both (i) and (ii)—is the claim that the justificatory status of justified basic beliefs originates from being the undefeated outputs of a reliable, cognitively integrated system that is capable of defeating them. Simply put, to be candidates for being justified, basic beliefs must be epistemically responsible and to be so they must be undefeated while being defeasible. The paper also offers a detailed, naturalistic analysis of the notion of cognitive integration. This long-due, mechanistic account of cognitive integration is then used to argue that an additional advantage of System Reliabilism is its unique position to account for the as yet unexplained intuition that responsible beliefs are also likely to be true.

According to accessibilism, there is an accessibility condition on justification. More specifically, accessibilism claims that facts about justification are a priori accessible, where a priori is used in the traditional sense that a condition is a priori just in case it doesn't depend on any of the sense modalities. The most prominent argument for accessibilism draws on BonJour and Lehrer's unfamiliar faculty scenarios. Recently, however, several objections have been raised against it. In this article, I defend the argument against three (...) prominent objections from the recent literature. (shrink)

The cases of Norman the Clairvoyant and Mr. Truetemp form classic counterexamples to the process reliabilist's claim that reliability is sufficient for prima facie justification. I discuss several ways in which contemporary reliabilists have tried to deal with these counterexamples, and argue that they are all unsuccessful. Instead, I propose that the most promising route lies with an appeal to a specific kind of higher-order defeat that is best cashed out in terms of properly functioning monitoring mechanisms.

Knowledge seems to need the admixture of de facto reliability and epistemic responsibility. But philosophers have had a hard time in attempting to combine them in order to achieve a satisfactory account of knowledge. In this paper I attempt to find a solution by capitalizing on the real and ubiquitous human phenomenon that is the social dispersal of epistemic labour through time. More precisely, the central objective of the paper is to deliver a novel and plausible social account of knowledge-relevant (...) responsibility and to consider the merits of the proposed combination of reliability and responsibility with respect to certain cases of unreflective epistemic subjects. O conhecimento parece precisar de uma combinação de confiabilidade de facto e responsabilidade epistêmica. Mas os filósofos têm tido grande dificuldade tentar combiná-las para alcançar uma teoria satisfatória do conhecimento. Este trabalho tenta encontrar uma solução baseada no fenômeno humano real e onipresente que é a dispersão social do trabalho epistêmico através do tempo. Mais precisamente, o objetivo central deste artigo é entregar uma teoria social de responsabilidade epistêmica nova e plausível e considerar os méritos de a combinação de confiabilidade e responsabilidade proposta relativas a certos casos de indivíduos epistemológicos não reflexivos.

This paper challenges the appeal to theory virtues in theory choice as well as the appeal to the intellectual and moral virtues of an agent as determining unique choices between empirically equivalent theories. After arguing that theoretical virtues do not determine the choice of one theory at the expense of another theory, I argue that nor does the appeal to intellectual and moral virtues single out one agent, who defends a particular theory, and exclude another agent defending an alternative theory. (...) I analyse Duhem’s concept of good sense and its recent interpretation in terms of virtue epistemology. I argue that the virtue epistemological interpretation does not show how good sense leads to conclusive choices and scientific progress. (shrink)

The idea that emotional experience is capable of lending immediate prima facie epistemic justification to evaluative belief has been amassing significant philosophical support in recent years. The proposal that it is my anger, say, that justifies my belief that I’ve been wronged putatively provides us with an intuitive and naturalised explanation as to how we receive immediate and defeasible justification for our evaluative beliefs. With many notable advocates in the literature, this justificatory thesis of emotion is fast becoming a central (...) facet in how we conceive of the emotions’ epistemic role with respect to our everyday lives. Interestingly, however, despite the fact that the justificatory thesis is fundamentally an epistemological proposal, comparatively little of the philosophical literature has been dedicated to exploring the epistemological avenues through which emotions might be capable of delivering such an epistemic yield. Accordingly, the central purpose of this thesis is to provide a novel and thorough analysis of how emotional experience might be capable of playing this justificatory role. Here, I present and evaluate three broad models of emotional justification: emotional dogmatism, emotional reliabilism, and agent-based views. Emotional dogmatist views, I argue, fail in virtue of being vulnerable to over-generalisation worries and problematic commitments to the contents of emotional awareness. Emotional reliabilism, while possessing the resources to avoid some objections, is vulnerable to worrisome clairvoyance-style challenges which establish the insufficiency of emotional reliability for epistemic justification. Finally, having learned our lessons from the shortcomings of these views, I argue that an agent-based theory grounded in the development of learned emotional competences provides the most plausible account of how emotional experience can epistemically justify evaluative belief. This discussion, I believe, will both illuminate contemporary discussions of the justificatory thesis of emotion found in the literature, and provide novel insight into the epistemic capacities of the emotions.

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

Many of our ordinary beliefs about the world around us are a result of inference from more fundamental beliefs. Foundationalists in epistemology have thought that, if these ordinary beliefs are to be rationally justified, the chain of inferential justification must terminate in a belief that is justified noninferentially. Foundationalists, of the internalist variety, have thought that the most plausible candidates for ending the regress of empirical justification are experiential states, the justifying features of which the believing subject is aware. The (...) Sellarsian dilemma, taking its name from philosopher Wilfrid Sellars, has been a persistent argument against foundationalist theories of epistemic justification. There have been various formulations of the dilemma over the years, but in its most general form it says that for any construal of an experiential state where the experiential state provides justification, the experiential state will need further justification. Sellars thought that an experience, all by itself, cannot provide justification unless we apply concepts to the experience. However, the application of concepts is judgmental and conceptual judgments, like beliefs, require further justification. So, the experiential state construed this way would perpetuate the regress it was designed to terminate. On the other hand, if the experiential state is construed such that it is not in need of justification, then it cannot itself provide justification. Both options are devastating to a foundationalist epistemology. My thesis is that a solution to all forms of the Sellarsian dilemma is to require for foundational justification direct awareness of the fit between one's conceptual judgment and the justifying experiential state. I concede that one must conceptualize one's experiential states for these states to play an epistemic role. However, I argue that conceptual judgments of this sort are the foundations. The importance of this solution is that it not only terminates the regress of justification but it also captures the primary intuitions that motivate internalism and foundationalism. This is to say that although I have framed my account as a response to the Sellarsian dilemma, it is not merely an ad hoc patch that avoids what stood as a serious problem. Instead, it is a return to what has motivated and what I take to be most persuasive about internalist foundationalism. (shrink)
