Some philosophers understand epistemological skepticism as merely presenting a paradox to be solved, a paradox given rise to by some apparently forceful arguments. I argue that such a view needs to be justified, and that the best way to do so is to show that we cannot help seeing skepticism as obviously false. The obviousness (to us) of the falsity of skepticism is, I suggest, explained by the fact that we cannot live without knowledge-beliefs (a knowledge-belief about the world is (...) a belief that a person or a group of people know that p, where p is an empirical proposition about the world). I then go on to argue for the indispensability of knowledge-beliefs. The first line of argument appeals to the practical aspects of our employment of the concept of knowledge, and the second line of argument draws on some Davidsonian ideas concerning understanding and massive agreement.

Resumen El objetivo de este trabajo es determinar la relevancia de la teoría informacional del conocimiento para el problema de la suerte epistémica. Argumento que el clásico enfoque de Dretske es equivalente a la condición de seguridad de Pritchard. Sin embargo, considero que esta manera de eludir la suerte epistémica exige lidiar con el llamado "problema de la generalidad". Argumento que una respuesta a este problema requiere una noción de seguridad diferente y propongo un enfoque informacional equivalente a esta versión (...) del requisito. Concluyo que este enfoque es preferible a la condición de seguridad propuesta porque desvela relaciones conceptuales entre los elementos que constituyen el conocimiento.The aim of this paper is to determine the relevance of an informational theory of knowledge to address recently discussed epistemic problems. I argue that Dretske's classical approach is equivalent to the safety condition proposed by Pritchard to avoid epistemic luck. However, I claim that Pritchard's condition has to be modified to avoid the so-called "generality problem" for reliabilism. I propose an alternative version of the requirement to deal with these problems and provide an equivalent informational condition. I conclude that this informational version is preferable since it reveals conceptual relationships between the constituents of knowledge. (shrink)

Much of what we know results from information sources on which we epistemically rely. This fact about epistemic reliance, however, stands in tension with a very powerful intuition governing knowledge, an intuition that Pritchard (e.g., 2010) has termed the “ability intuition,” the idea that a believer's “reliable cognitive faculties are the most salient part of the total set of causal factors that give rise to [their] believing the truth” (Vaesen, 2011, p. 518; compare Greco, 2003; 2009; 2010). In this paper (...) I suggest that this tension may indeed be ineliminable. I proceed by canvassing some representative attempts to reconcile epistemic reliance and the ability intuition. In doing so, I suggest that all of these attempts founder on one or the other of two elements of what I've previously described (Shieber, 2013, 2015) as a “personalist presumption” in discussions of social epistemology: an excessive focus on (i) reliability filters within the persons who are the recipients of information or (ii) on reliable truth‐tracking and ‐conveying abilities in the persons who are the transmitters of information. In conclusion, I suggest how best to resolve the tension: by abandoning the ability intuition. (shrink)

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one knows that they (...) do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

The radical probabilist counsels the prudent never to put away uncertainty, and hence always to balance judgment with probabilities of various sizes. Against this counsel I shall advise in favor of the practice of full belief — at least for some occasions. This advice rests on the fact that it is sometimes in a person's interests to accept certain propositions as a means of bringing it about that others recognize oneself as having accepted those propositions. With the pragmatists, therefore, I (...) shall reject the view that belief formation must in every instance be a truth-directed affair. Unlike the pragmatists, however, I shall conclude that the enterprise of belief formation is not directed exclusively, or even primarily, at attaining knowledge. In other words, pursuit of that which it profits to believe, on the one hand, and pursuit of knowledge on the other, are distinct enterprises, which overlap (when they do) only accidentally.

Naturalists seek continuity between epistemology and science. Critics argue this illegitimately expands science into epistemology and commits the fallacy of scientism. Must naturalists commit this fallacy? I defend a conception of naturalized epistemology which upholds the non-identity of epistemic ends, norms, and concepts with scientific evidential ends, norms, and concepts. I argue it enables naturalists to avoid three leading scientistic fallacies: dogmatism, one dimensionalism, and granting science an epistemic monopoly.

The approach set forth by Edward Craig in Knowledge and the State of Nature has a greater explanatory value than it has been granted to date, and his suitably modified project can resolve a number of puzzling issues regarding the value of knowledge. The paper argues that a novel theory that relates knowledge to testimony is capable of explaining why knowledge is more valuable than mere true belief and why it has a distinctive value. Significantly, this theory avoids the recently (...) advanced revisionism regarding the focus of epistemological research. La aproximación de Edward Craig en Knowledge and the State of Nature tiene más poder explicativo del apreciado hasta ahora, y su proyecto, adecuadamente modificado, puede resolver un número de asuntos sobre el valor del conocimiento que parecen desconcertantes. Se argumenta que una novedosa teoría de conocimiento que lo relaciona con el testimonio puede explicar por qué el conocimiento es más valioso que la mera creencia verdadera, y por qué tiene un valor distintivo. Significativamente, la teoría evita un revisionismo, recientemente avanzado, con respecto al foco de la investigación epistemológica. (shrink)

This paper motivates an account of knowledge as a social kind, following a cue by Edward Craig, which captures two major insights behind social and feminist epistemologies, in particular our epistemic interdependence concerning knowledge and the role of social regulative practices in understanding knowledge.

I argue that epistemologists’ use of the term ‘epistemic’ has led to serious confusion in the discussion of epistemological issues. The source of the problem is that ‘epistemic’ functions largely as an undefined technical term. I show how this confusion has infected discussions of the nature of epistemic justification, epistemic norms for evidence gathering, and knowledge norms for assertion and belief.

In Reconstructing Reason and Representation, Murray Clarke offers a detailed study of the philosophical implications of evolutionary psychology. In doing so, he offers new solutions to key problems in epistemology and philosophy of mind, including misrepresentation and rationality. He proposes a naturalistic approach to reason and representation that is informed by evolutionary psychology, and, expanding on the massive modularity thesis advanced in work by Leda Cosmides and John Tooby, argues for a modular, adapticist account of misrepresentation and knowledge. Just as (...) the reliability of representation can be defended on the basis of an account of the proper function of cognitive modularity, misrepresentation can be explained through an appeal to the "gap theory," by noting the divergence between the proper and actual domains of cognitive modules in a massively modular mind.Clarke argues for an externalist, modular reliabilism by suggesting that evolution has equipped us with generally reliable inferential systems even if they do not always produce true beliefs. He argues that reliable deductive and inductive inference occurs only when cognitive modules deal with actual domains that are sufficiently similar to their proper domains. This psychologically informed, naturalized adapticism leads to the suggestion that knowledge is a set of natural kinds housed in the modules of a massively modular mind. Typically, the proper function of these cognitive modules is to provide us with truths that enable us to satisfy our basic biological needs. Beyond reasoning modules, other cognitive modules discussed include the ability to orient ourselves in space, and our abilities with language, numbers, object reasoning, and social understanding. Clarke also defends Cosmides and Tooby's massive modularity hypothesis against such critics as Jerry Fodor by demonstrating that these critics consistently misrepresent Cosmides and Tooby's position.

There are both externalist and internalist theories of the phenomenal content of conscious experiences. Externalists like Dretske and Tye treat the phenomenal content of conscious states as representations of external properties. Internalists think that phenomenal conscious states are reducible to electrochemical states of the brain in the style of the type-type identity theory. In this paper, we side with the representationalists and visit a dispute between them over the test case of Swampman. Does Swampman have conscious phenomenal states or not? (...) Dretske and Tye disagree on this issue. We try to settle the dispute in favor of Dretske's theory. (shrink)

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.

This paper defends the view that a correct analysis of knowledge must take empirical data into consideration. The data here provided is from experimental psychology, namely from phenomena involving unconscious cognition.

In this dissertation, I argue that an account of epistemic injustice sensitive to interlocking oppressions must take us beyond injustice to human knowers. Although several feminist epistemologists argue for the incorporation of all forms of oppression into their analyses, feminist epistemology remains for the most part an anthropocentric enterprise. Yet insofar as a reduction to animal irrationality has been central to the epistemic injustice of both humans and animals, I propose that in addition to axes of gender, race, class and (...) sex, feminist epistemology must register the animal-human dichotomy as a fundamental driving mechanism inherent in epistemic injustice. From the perspective of a truly liberatory epistemology, I thus argue for an expanded account of epistemic injustice that is both 1) sufficiently attentive to the way injustices to human knowers continue to rely on animal oppression and 2) that accommodates epistemic injustices against animal knowers.
