What is the relation between computation and intennonality? Cognition presup- poses intentionality (or semantics). This much is certain. So, if, according to com- putationalism, cognition is computation, then computation, mo, presupposes..

Presents a theory of bullshit, how it differs from lying, how those who engage in it change the rules of conversation, and how indulgence in bullshit can alter a person's ability to tell the truth.

Recent conversation has blurred two very different social epistemic phenomena: echo chambers and epistemic bubbles. Members of epistemic bubbles merely lack exposure to relevant information and arguments. Members of echo chambers, on the other hand, have been brought to systematically distrust all outside sources. In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined. It is crucial to keep these phenomena distinct. First, echo chambers can explain the post-truth phenomena in a way that epistemic (...) bubbles cannot. Second, each type of structure requires a distinct intervention. Mere exposure to evidence can shatter an epistemic bubble, but may actually reinforce an echo chamber. Finally, echo chambers are much harder to escape. Once in their grip, an agent may act with epistemic virtue, but social context will pervert those actions. Escape from an echo chamber may require a radical rebooting of one's belief system.

This paper identifies and elucidates a hitherto unnamed epistemic vice: epistemic insouciance. Epistemic insouciance consists in a casual lack of concern about whether one’s beliefs have any basis in reality or are adequately supported by the best available evidence. The primary intellectual product of epistemic insouciance is bullshit in Frankfurt’s sense. This paper clarifies the notion of epistemic insouciance and argues that epistemic insouciance is both an epistemic posture and an epistemic vice. Epistemic postures are attitudes towards epistemic objects such (...) as knowledge, evidence, or inquiry. Epistemic vices are defined as character traits, attitudes, or thinking styles that systematically obstruct the gaining, keeping or sharing of knowledge. Epistemic insouciance is not just a posture but an affective posture. Such postures are distinguished from epistemic stances, which are policies that one can adopt or reject. Epistemic malevolence is an example of an epistemically vicious epistemic stance that issues in active attempts to undermine the knowledge possessed by a specified group of individuals. An example of epistemic malevolence in action is the so-called ‘tobacco strategy.’ I argue that epistemic malevolence undermines knowledge by instilling doubts about respectable sources of evidence.

Did you know that Hillary Clinton sold weapons to ISIS? Or that Mike Pence called Michelle Obama “the most vulgar First Lady we’ve ever had”? No, you didn’t know these things. You couldn’t know them, because these claims are false.1 But many American voters believed them.One of the most distinctive features of the 2016 campaign was the rise of “fake news,” factually false claims circulated on social media, usually via channels of partisan camaraderie. Media analysts and social scientists are still (...) debating what role fake news played in Trump’s victory.2 But whether or not it drove the outcome, fake news certainly affected the choices of some individual voters.Why were people willing to believe easily...

Vice epistemology is the philosophical study of the nature, identity, and epistemological significance of intellectual vices. Such vices include gullibility, dogmatism, prejudice, closed-mindedness, and negligence. These are intellectual character vices, that is, intellectual vices that are also character traits. I ask how the notion of an intellectual character vice should be understood, whether such vices exist, and how they might be epistemologically significant. The proposal is that intellectual character vices are intellectual character traits that impede effective and responsible inquiry. I (...) argue that situationist critiques of virtue epistemology pose no significant threat to this proposal. Studies by social psychologists of belief in conspiracy theories suggest that it is sometimes appropriate to explain questionable beliefs by reference to intellectual character vices. Neither ‘regulative’ nor ‘analytic’ epistemology has any good reason to question the epistemological significance of such vices. (shrink)

The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (shrink)

Causal claims are context sensitive. According to the old orthodoxy (Mackie 1974, Lewis 1986, inter alia), the context sensitivity of causal claims is all due to conversational pragmatics. According to the new contextualists (Hitchcock 1996, Woodward 2003, Maslen 2004, Menzies 2004, Schaffer 2005, and Hall ms), at least some of the context sensitivity of causal claims is semantic in nature. I want to discuss the prospects for causal contextualism, by asking why causal claims are context sensitive, what they are sensitive (...) to, and where they are sensitive to it. (shrink)

As a general rule, whenever a hearer is justified in forming the belief that p on the basis of a speaker’s testimony, she will also be justified in assuming that the speaker has formed her belief appropriately in light of a relevantly large and representative sample of the evidence that bears on p. In simpler terms, a justification for taking someone’s testimony entails a justification for trusting her assessment of the evidence. This introduces the possibility of what I will call (...) “evidential preemption.” Evidential preemption occurs when a speaker, in addition to offering testimony that p, also warns the hearer of the likelihood that she will subsequently be confronted with apparently contrary evidence: this is done, however, not so as to encourage the hearer to temper her confidence in p in anticipation of that evidence, but rather to suggest that the (apparently) contrary evidence is in fact misleading evidence or evidence that has already been taken into account. Either way, the speaker is signalling to the hearer that the subsequent disclosure of this evidence will not require her to significantly revise her belief that p. Such preemption can effectively inoculate an audience against future contrary evidence, and thereby creates an opening for a form of exploitative manipulation that I will call “epistemic grooming.” Nonetheless, I argue, not all uses of evidential preemption are nefarious; it can also serve as an important tool for guiding epistemically limited agents though complex evidential scenarios.

The primary goal of this paper is to propose a working analysis of the disposition of closed-mindedness. I argue that closed-mindedness (CM) is an unwillingness or inability to engage (seriously) with relevant intellectual options. Dogmatism (DG) is one kind of closed-mindedness: it is an unwillingness to engage seriously with relevant alternatives to the beliefs one already holds. I do not assume that the disposition of closed-mindedness is always an intellectual vice; rather I treat the analysis of the disposition, and its (...) status as an intellectual vice, as separate questions. The concluding section develops a framework for determining the conditions under which closed-mindedness will be an intellectual vice. (shrink)

Is closed-mindedness always an intellectual vice? Are there conditions in which it might be an intellectual virtue? This paper adopts a working analysis of closed-mindedness as an unwillingness or inability to engage seriously with relevant intellectual options. In standard cases, closed-mindedness will be an intellectual vice. But, in epistemically hostile environments, closed-mindedness will be an intellectual virtue.
