I begin by “deconstructing” the title and explaining that Feyerabend does not really use the word “ontology”, though he does call his position sometimes (and the “sometimes” is important) ontological realism. I explain that he talks about his position as indifferently a “general methodology” or a “general cosmology”, and that he seems to be be hostile to the very enterprise of ontology, conceived of as “school philosophy”. I then go on to say that there is perhaps a concept of a (...) different type of ontology, that I call a “diachronic ontology” that perhaps he would have accepted,and that is very different from ontology as ordinarily thought, which I claim to be synchronic ontology (having no room for the dialogue with Being, but just supposing that Being is already and always there without our contribution). I discuss Althusser and Graham Harman as exemplifying synchronic ontology, giving a reading of Harman’s recent book THE THIRD TABLE. I then discuss Feyerabend’s ideas as showing a different way, that of a diachronic ontology, in which there is no stable framework or fixed path. I end with Andrew Pickering whose essay NEW ONTOLOGIES makes a similar distinction to mine, expressing it in the imagistic terms of a De Kooningian (diachronic) versus a Mondrianesque (synchronic) approach.

It is sometimes alleged that “the reliability challenge” to moral realism is equally compelling against mathematical realism. This allegation is of interest. The reliability challenge to moral realism is increasingly taken to be the most serious challenge to moral realism. However, the specific considerations that are said to motivate it – such as considerations of rational dubitability and evolutionary influence – are widely held not to motivate an analogous challenge to mathematical realism. If it turned out that, in fact, they (...) do, then one might have to choose between moral realism and mathematical realism.<br><br>Nevertheless, the relevant allegation has never been clarified, let alone evaluated. In this paper, I clarify and evaluate it. I argue that the allegation is plausible, but depends on theses in the philosophy of mathematics that are widely doubted. One upshot of the discussion is that mathematical realism faces challenges that have not been widely appreciated. Another is that the reliability challenge to moral realism may not be the most interesting epistemological challenge to moral realism. (shrink)

Criticisms of Karl Popper’s critical rationalist epistemology are often confused and misleading. In part that is due to Popper’s somewhat lax use of language, in which technical terms are used in more than one sense. I attempt to clarify Popper’s views by regimenting his terminology. The result is offered as a clear and concise exposition of the main points of Popper’s epistemology. This is an updated version of a paper that was published in Cosmos + Taxis 6 (6+7): 49-54 (2019).

I argue for three points: First, evidence of the primacy of knowledge representation is not evidence of primacy of knowledge. Second, knowledge-oriented mindreading research should also focus on misrepresentations and biased representations of knowledge. Third, knowledge-oriented mindreading research must confront the problem of the gold standard that arises when disagreement about knowledge complicates the interpretation of empirical findings.

Selim Berker argues that epistemic consequentialism is pervasive in epistemology and that epistemic consequentialism is structurally flawed. is incorrect, however. I distinguish between epistemic consequentialism and epistemic instrumentalism and argue that most putative consequentialists should be considered instrumentalists. I also identify the structural problem of epistemic consequentialism Berker attempts to pinpoint and show that epistemic instrumentalism does not have the consequentialist problem.

What role does ‘ordinary language philosophy’ play in the defense of common sense beliefs? J.L. Austin and Ludwig Wittgenstein each give central place to ordinary language in their responses to skeptical challenges to common sense beliefs. But Austin and Wittgenstein do not always respond to such challenges in the same way, and their working methods are different. In this paper, I compare Austin’s and Wittgenstein’s metaphilosophical positions, and show that they share many metaphilosophical commitments. I then examine Austin and Wittgenstein’s (...) respective takes on the problem of other minds and the problem of our knowledge of the external world. Interestingly, we find Wittgenstein employing methods more frequently associated Austin and vice versa. Moreover, we find that a variety of defenses of common sense beliefs are compatible with ‘ordinary language philosophy.’. (shrink)

This book is addresses a topic that has received little or no attention in orthodox epistemology. Typical epistemological investigation focuses almost exclusively on knowledge, where knowing that something is the case importantly implies that what is believed is strictly true. This condition on knowledge is known as factivity and it is, to be sure, a bit of epistemological orthodoxy. So, if a belief is to qualify as knowledge according to the orthodox view it cannot be false. There is also an (...) increasingly influential group of epistemologists who argue that one ought to act only on what one knows, because truth of belief is the surest way to guarantee that our actions work out as planned. They defend what is known as the knowledge norm for action. This view is typically justified in virtue of the idea that successful intentional action should stem from knowledge because knowledge is a factive propositional attitude and it is, as a result, success-prone with respect to intentional action. In other words, true beliefs that constitute knowledge are the rationally normative standard for successful acting. But, there are clearly multitudes of cases where epistemic agents operate successfully and even rationally on the basis of beliefs that are false. That this is the case is not especially controversial. Sometimes false beliefs facilitate successful action. Of course, this can be because the agent is simply lucky. However, there is something particularly important about some false beliefs that relates to successful action but not in virtue of luck. While not strictly true, the beliefs in question are close to the truth or approximately true. This gives rise to the possibility that there are knowledge-like states that play roles very similar to knowledge but which are only quasi-factive. That is to say such states imply approximate truth and do not imply strict truth. Moreover, often such beliefs facilitate successful action in virtue of their being approximately true and this suggests a much more plausible norm for successful action that encompasses both cases of rational action guided by such quasi-factive states as well as cases of rational action guided by knowledge. The thesis of this book is that quasi-factive knowledge-like states are far more common that epistemologists have acknowledge and the book introduces a theory of such states and how they give rise to a much more reasonable account of the norms for action. This involves some tricky issues concerning approximate truth, the rationality of believing not strictly true claims, the justification of approximately true beliefs, the nature of false but approximately true evidence, the norms of belief, knowledge and quasi-knowledge, etc. (shrink)

From antiquity through the twentieth century, philosophers have hypothesized that, intuitively, it is harder to know negations than to know affirmations. This paper provides direct evidence for that hypothesis. In a series of studies, I found that people naturally view negations as harder to know than affirmations. Participants read simple scenarios and made judgments about truth, probability, belief, and knowledge. Participants were more likely to attribute knowledge of an outcome when framed affirmatively than when framed negatively. Participants did this even (...) though the affirmative and negative framings were logically equivalent. The asymmetry was unique to knowledge attributions: it did not occur when participants rated truth, probability, or belief. These findings show new consequences of negation on people’s judgments and reasoning and can inform philosophical theorizing about the ordinary concept of knowledge. (shrink)

Hope, in its propositional construction "I hope that p," is compatible with a stated chance for the speaker that not-p. On fallibilist construals of knowledge, knowledge is compatible with a chance of being wrong, such that one can know that p even though there is an epistemic chance for one that not-p. But self-ascriptions of propositional hope that p seem to be incompatible, in some sense, with self-ascriptions of knowing whether p. Data from conjoining hope self-ascription with outright assertions, with (...) first- and third-person knowledge ascriptions, and with factive predicates suggest a problem: when combined with a plausible principle on the rationality of hope, they suggest that fallibilism is false. By contrast, the infallibilist about knowledge can straightforwardly explain why knowledge would be incompatible with hope, and can offer a simple and unified explanation of all the linguistic data introduced here. This suggests that fallibilists bear an explanatory burden which has been hitherto overlooked. (shrink)

This chapter explores an unappreciated psychological dimension of intellectual humility. In particular, I argue there is a plausible connection between intellectual humility and epistemic egocentrism. Epistemic egocentrism is a well-known cognitive bias – often called ‘the curse of knowledge’ – whereby an agent attributes his or her own mental states to other people. I hypothesize that an individual who exhibits this bias is more likely to possess a variety of traits that are characteristic of intellectual humility. This is surprising because (...) intellectual humility is often regarded as an antidote to cognitive biases, whereas I claim that a particular cognitive bias (namely, the curse of knowledge) may help foster an intellectual virtue.

We investigate claims about the frequency of "know" made by philosophers. Our investigation has several overlapping aims. First, we aim to show what is required to confirm or disconfirm philosophers’ claims about the comparative frequency of different uses of philosophically interesting expressions. Second, we aim to show how using linguistic corpora as tools for investigating meaning is a productive methodology, in the sense that it yields discoveries about the use of language that philosophers would have overlooked if they remained in (...) their "armchairs of an afternoon", to use J.L. Austin’s phrase. Third, we discuss facts about the meaning of "know" that so far have been ignored in philosophy, with the aim of reorienting discussions of the relevance of ordinary language for philosophical theorizing.

Edmund Gettier (1963) argued that there can be justified true belief (JTB) that is not knowledge. I question the correctness of his argument by showing that Smith of Gettier’s famous examples does not earn justification for his incidentally true beliefs, while a doxastically more conscientious person S would come to hold justified but false beliefs. So, Gettier’s (and analogous) cases do not result in justified _and_ true belief. This is due to a tension between deductive closure of justification and evidential (...) support. For being justified, any believing, disbelieving, or withholding of deductively inferred propositions must be distributed proportionally to given evidential support. This proportionality principle has primacy over deductive closure in case of conflict. Although my argument does not save the JTB-account, it explains why subjects in Gettier situations do not earn knowledge. (shrink)

Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. Defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. Detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. Debates about relativism permeate the whole spectrum of philosophical sub-disciplines. From ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy (...) has felt the need to respond to this heady and seemingly subversive idea. Discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called “analytic and continental” camps in philosophy. And yet, despite a long history of debate going back to Plato and an increasingly large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. This entry attempts to provide a broad account of the many ways in which “relativism” has been defined, explained, defended and criticized. (shrink)

The notion of relevance plays a role in many accounts of knowledge and knowledge ascription. Although use of the notion is well-motivated, theorists struggle to codify relevance. A reasonable person standard of relevance addresses this codification problem, and provides an objective and flexible standard of relevance; however, treating relevance as reasonableness seems to allow practical factors to determine whether one has knowledge or not—so-called “pragmatic encroachment.” I argue that a fuller understanding of reasonableness and of the role of practical factors (...) in the acquisition of knowledge lets us avoid pragmatic encroachment. (shrink)

A common objection to both contextualism and relativism about knowledge ascriptions is that they threaten knowledge norms of assertion and action. Consequently, if there is good reason to accept knowledge norms of assertion or action, there is good reason to reject both contextualism and relativism. In this paper we argue that neither contextualism nor relativism threaten knowledge norms of assertion or action.

Abstract The purpose of this paper is twofold: (i) we will argue that formal semantics might have faltered due to its failure in distinguishing between two fundamentally very different types of concepts, namely ontological concepts, that should be types in a strongly-typed ontology, and logical concepts, that are predicates corresponding to properties of, and relations between, objects of various ontological types; and (ii) we show that accounting for these differences amounts to a new formal semantics; one that integrates lexical and (...) compositional semantics in one coherent framework and one where formal semantics is embedded with a strongly typed ontology; an ontology that reflects our commonsense knowledge of the world and the way we talk about it in ordinary language. We will show how in such a framework a number of challenges in the semantics of natural language are adequately and systematically treated. (shrink)

Epistemic probability theories of luck come in two versions. They are easiest to distinguish by the epistemic property they claim eliminates luck. One view says that the property is knowledge. The other view says that the property is being guaranteed by a subject’s evidence. Asbjørn Steglich-Petersen defends the Knowledge Account. He has recently argued that his view is preferable to my Epistemic Analysis of Luck, which defines luck in terms of evidential probability. In this paper, I defend EAL against Steglich-Petersen’s (...) arguments, clarify the view, and argue for the explanatory significance of EAL with respect to some core epistemological issues. My overall goal is to show that an epistemic probability account of luck rooted in the concepts of evidence and evidential support remains a viable and fruitful overall account of luck. (shrink)

Some epistemologists and philosophers of mind hold that the non-epistemic perceptual relation of which feature-seeing and object-seeing are special cases is the foundation of perceptual knowledge. This paper argues that such relations are best understood as having only a technological role in explaining perceptual knowledge. After introducing the opposing view in §1, §2 considers why its defenders deny that some cases in which one has perceptual knowledge without the relevant acquaintance relations are counterexamples, detailing their case for lurking inferential epistemology. (...) §§3-4 suggest that this strategy fails in many other cases. While there is a computational tale that might be deemed ‘inferential’ in these cases, there is no corresponding tale in epistemic structure, not even if one rejects what Siegel (2017) calls the ‘Reckoning Model’ of inference. §5 offers a more fundamental dilemma. §6 concludes that there is only a technological role for non-epistemic perception in grounding perceptual knowledge, but allows that it might play a more-than-technological role elsewhere.

This paper advances our understanding of the norms of assertion in two ways. First, I evaluate recent studies claiming to discredit an important earlier finding which supports the hypothesis that assertion has a factive norm. In particular, I evaluate whether it was due to stimuli mentioning that a speaker’s evidence was fallible. Second, I evaluate the hypothesis that assertion has a truth-insensitive standard of justification. In particular, I evaluate the claim that switching an assertion from true to false, while holding (...) all else objectively constant, is irrelevant to attributions of justification. Two pre-registered experiments provide decisive evidence against each claim. In the first experiment, switching from mentioning to not mentioning fallibility made no difference to assertability attributions, thereby disproving the criticism concerning fallibility. By contrast, switching an assertion from true to false decreased the rate of assertability attribution from over 90% to less than 20%, thereby replicating and vindicating the original finding supporting a factive norm. In the second experiment, switching an assertion from true to false decreased the rate of justification attribution from over 80 to 10%, thereby undermining the hypothesis that assertion’s standard of justification is truth-insensitive. The second experiment also demonstrates that perspective-taking influences attributions of justification, and it provides initial evidence that the standard of justification for assertion is stricter than the standard for belief.

How children seek knowledge and evaluate claims may depend on their understanding of the source of knowledge. What shifts in their understandings about why scientists might disagree and how claims about the state of the world are justified? Until about the age of 41/2, knowledge is seen as self-evident. Children believe that knowledge of reality comes directly through our senses and what others tell us. They appeal to these external sources in order to know. The attainment of Theory of Mind (...) (ToM) at this age is commonly seen as the significant shift in development in understanding disagreements in knowledge claims. Children attaining ToM understand that someone exposed to incorrect or incomplete information might have false beliefs. Disagreement, then, is still attributed to objective sources of knowledge. The current study examines the later developing Interpretive Theory of Mind (iToM) as the basis for children’s understanding of how people with access to the same information might disagree and what this means for how to provide justification for a knowledge claim. Fourteen 2nd graders with the most iToM responses to four tasks and 14 with the fewest iToM responses were selected from a larger sample of 91. In analyses of interviews about a story in which two experts make different claims about a scientific phenomenon, those in the high iToM group noted subjective perspective and processes as the source of disagreement and suggested the need for investigation as the means to knowing. In contrast, those in the low iToM group mostly could not explain the source of disagreement and held that knowledge is acquired from external sources. A comparison of the interviews regarding the science story 2 years later allows for a qualitative description of the development. Those in the low iToM group showed more general recognition of subjective and constructive processes in knowing whereas those in the high iToM group identified interpretive processes and the relativity of perspectives with implications for how observations were conducted and interpreted. Only those in the high iToM group referred to the importance of evidence as a basis for knowledge claims at either point in the study. (shrink)

We present a taxonomy of errors in the scientific literature and an account of how the errors are distributed over the categories. We have developed the taxonomy by studying substantial errors in the scientific literature as described in retraction notices published in the journal Science over the past 35 years. We then examine how the sorts of errors that lead to retracted papers can be prevented and detected, considering the perspective of collaborating scientists, journal editors and referees, and readers of (...) the published articles.

ABSTRACTDoes knowledge entail belief? This paper argues that the answer depends on how one interprets ‘belief’. There are two different notions of belief: belief as such and belief for knowledge. They often differ in their degrees of conviction such that one but not both might be present in a particular case. The core of the paper is dedicated to a defense of this overlooked distinction. The beginning of the paper presents the distinction. It then presents two cases which are supposed (...) to back up the claim that there is an important distinction here; I also offer some explanations concerning the structure of these cases. Finally, I add further considerations in support of the core thesis, and discuss objections. The distinction is important as such but also has interesting implications concerning the much discussed ‘entailment thesis’ according to which knowledge entails belief. It is argued here that even if knowledge entails belief-for-knowledge, it does not entail belief-as-such. This constitutes an interesting middle position and compromise in the philosophical debate about the entailment thesis. One further implication of this paper is that the discussion about the entailment thesis needs to take degrees of conviction seriously. Still another implication is that epistemic contextualists can deal very well with the relevant phenomena. (shrink)

This paper develops a new challenge for moral noncognitivism. In brief, the challenge is this: Beliefs — both moral and non-moral — are epistemically evaluable, whereas desires are not. It is tempting to explain this difference in terms of differences in the functional roles of beliefs and desires. However, this explanation stands in tension with noncognitivism, which maintains that moral beliefs have a desire-like functional role. After critically reviewing some initial responses to the challenge, I suggest a solution, which involves (...) rethinking the functional relationship between desire and belief. (shrink)

Hope is an attitude with a distinctive epistemological dimension: it is incompatible with knowledge. This chapter examines hope as it relates to knowledge but also to probability and inductive considerations. Such epistemic constraints can make hope either impossible, or, when hope remains possible, they affect how one’s epistemic situation can make hope rational rather than irrational. Such issues are especially relevant to when hopefulness may permissibly figure in practical deliberation over a course of action. So I consider cases of second-order (...) inductive reflection on when one should, or should not, be hopeful for an outcome with which one has a long record of experience: in other words, what is the epistemology behind when one should, if ever, stop hoping for outcomes which have failed one many times in the past?

Extended cognition theorists argue that cognitive processes constitutively depend on resources that are neither organically composed, nor located inside the bodily boundaries of the agent, provided certain conditions on the integration of those processes into the agent’s cognitive architecture are met. Epistemologists, however, worry that in so far as such cognitively integrated processes are epistemically relevant, agents could thus come to enjoy an untoward explosion of knowledge. This paper develops and defends an approach to cognitive integration—cluster-model functionalism—which finds application in (...) both domains of inquiry, and which meets the challenge posed by putative cases of cognitive or epistemic bloat.

Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is—at the very—least understandable and if we take an evidential approach—judging individual conspiracy theories on their particular merits—belief in such theories turns out to be warranted in a range of cases. Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, showing that the evidential problems typically associated with conspiracy (...) theories are not unique to such theories. As such, if there is a problem with the conspiracy theorist’s use of evidence, it is one of principle: is the principle which guides their use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (shrink)

One challenge for moderate invariantists is to explain why we tend to deny knowledge to subjects in high stakes when the target propositions seem to be inappropriate premises for practical reasoning. According to an account suggested by Williamson, our intuitive judgments are erroneous due to an alleged failure to acknowledge the distinction between first-order and higher-order knowledge: the high-stakes subject lacks the latter but possesses the former. In this paper, I provide three objections to Williamson’s account: i) his account delivers (...) counterintuitive verdicts about what it is appropriate for a high-stakes subject to do; ii) the high-stakes subject doesn’t need iterated knowledge in order to be regarded as appropriately relying on the relevant proposition in practical reasoning; iii) Williamson’s account doesn’t provide a good explanation of why the high-stakes subject would be blameworthy if she were relying on the relevant proposition in her practical reasoning.

This book is about knowledge and its value. The central hypothesis is that humans think and speak of knowing in order to identify reliable informants, which is vital for human survival, cooperation, and flourishing. This simple idea is used to answer an array of complex and consequential philosophical questions. -/- (Here's a promotion code to save 30% if you order online at Oxford University Press: AAFLYG6).

The existential insecurity of human beings has induced them to create protective spheres of symbols: myths, religions, values, belief systems, theories, etc. Rationality is one of the key factors contributing to the construction of civilisation in technical and symbolic terms. As Hankiss has emphasised, protective spheres of symbols may collapse – thus causing a profound social crisis. Social and political transformations had a tremendous impact at the end of the 20th century. As a result, management theories have been revised in (...) order to deal with transition and uncertainty. Francis Fukuyama's approach is supportive of hierarchical organisation as the best solution when facing a 'disruption'. The notion of Homo Hierarchicus has been based on, allegedly, rational presumptions. This paper contributes to the discussion on hierarchy within contemporary organisations. It criticises so-called 'natural' and 'rational' necessities justifying hierarchy. A key issue identified by the paper is the formalisation of language in claiming value-free knowledge and 'detached' observation as the basis for neutral rationality and aspired efficiency. This should be seriously reconsidered as hindering rather than aiding understanding of social complexity. All in all, Homo Hierarchicus appears to be misleading rather than helping symbolic sphere or construct. (shrink)

In this discussion note, I put forth an argument from the factivity of knowledge for the conclusion that knowledge is epistemic certainty. If this argument is sound, then epistemologists who think that knowledge is factive are thereby also committed to the view that knowledge is epistemic certainty.

The paper highlights how a popular version of epistemological disjunctivism labors under a kind of 'internalist challenge'—a challenge that seems to have gone largely unacknowledged by disjunctivists. This is the challenge to vindicate the supposed 'internalist insight' that disjunctivists claim their view does well to protect. The paper argues that if we advance disjunctivism within a context that recognizes a distinction between merely functional and judgmental belief, we get a view that easily overcomes the internalist challenge.

Over 40 years ago I read a small grey book with metaphysics in the title which began with the words “Metaphysics is dead. Wittgenstein has killed it.” I am one of many who agree but sadly the rest of the world has not gotten the message. Shoemaker’s work is nonsense on stilts but is unusual only in that it never deviates into sense from the first paragraph to the last. At least with Dennett, Carruthers, Churchland etc. one gets a breath (...) of fresh air when they discuss cognitive science (imagining they are still doing philosophy). As W showed so beautifully, the confusions that lead to metaphysics are universal and nearly inescapable aspects of our psychology. They occur not only in all thinking on behavior but throughout science as well. It’s easy to find examples in Hawking, Weinberg, Penrose, Green, who of course have no idea they have left science and entered metaphysics, that the statement they just made is not a matter of fact at all but a matter of conceptual (linguistic) confusion. “Law, event, space, time, force, matter, proof, connection, cause, follows, physical”, etc., all have clear uses in certain technical contexts, but these blend insensibly into quite different uses that have little in common but the spelling. Since it is pointless to waste time deconstructing Shoemaker line by line, showing the same errors over and over, I will describe some facts about how our psychology (language) works and with this outline and the references I give it is quite straightforward to give a meaningful description of the world in place of the metaphysical fantasies. If I were to debate Shoemaker we would never get beyond the title. Horwich gives one of the most beautiful summaries of where an understanding of Wittgenstein leaves us that I have ever seen. “There must be no attempt to explain our linguistic/conceptual activity (PI 126) as in Frege’s reduction of arithmetic to logic; no attempt to give it epistemological foundations (PI 124) as in meaning based accounts of a priori knowledge; no attempt to characterize idealized forms of it (PI 130) as in sense logics; no attempt to reform it (PI 124, 132) as in Mackie’s error theory or Dummett’s intuitionism; no attempt to streamline it (PI 133) as in Quine’s account of existence; no attempt to make it more consistent (PI 132) as in Tarski’s response to the liar paradoxes; and no attempt to make it more complete (PI 133) as in the settling of questions of personal identity for bizarre hypothetical ‘teleportation’ scenarios.” Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019). Those interested in more of my writings may see ‘Talking Monkeys--Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet--Articles and Reviews 2006-2019 3rd ed (2019) and Suicidal Utopian Delusions in the 21st Century 4th ed (2019).

Philosophers have debated whether it is possible to knowledgeably infer a conclusion from a false premise. For example, if a fan believes that the actress’s dress is blue, but the dress is actually green, can the fan knowledgeably infer “the dress is not red” from “the dress is blue”? One aspect of this debate concerns what the intuitively correct verdict is about specific cases such as this. Here I report a simple behavioral experiment that helps answer this question. The main (...) finding is that people attribute knowledge in cases where a true conclusion is inferred from a false premise. People did this despite judging that the premise was false and unknown. People also viewed the agent as inferring the conclusion from the premise. In closely matched conditions where the conclusion was false, people did not attribute knowledge of the conclusion. These results support the view that the ordinary knowledge concept includes in its extension cases of knowledge inferred from false premises. (shrink)

We report the results of four empirical studies designed to investigate the extent to which an epistemic closure principle for knowledge is reflected in folk epistemology. Previous work by Turri (2015a) suggested that our shared epistemic practices may only include a source-relative closure principle—one that applies to perceptual beliefs but not to inferential beliefs. We argue that the results of our studies provide reason for thinking that individuals are making a performance error when their knowledge attributions and denials conflict with (...) the closure principle. When we used research materials that overcome what we think are difficulties with Turri’s original materials, we found that participants did not reject closure. Furthermore, when we presented Turri’s original materials to non-philosophers with expertise in deductive reasoning (viz., professional mathematicians), they endorsed closure for both perceptual and inferential beliefs. Our results suggest that an unrestricted closure principle—one that applies to all beliefs, regardless of their source—provides a better model of folk patterns of knowledge attribution than a source-relative closure principle.

The value of knowledge has always been a central topic within epistemology. Going all the way back to Plato’s Meno, philosophers have asked, why is knowledge more valuable than mere true belief? Interest in this question has grown in recent years, with theorists proposing a range of answers. But some reject the premise of the question and claim that the value of knowledge is ‘swamped’ by the value of true belief. And others argue that statuses other than knowledge, such as (...) justification or understanding, are distinctively valuable. We will call the general question of why knowledge is valuable the value problem. (shrink)

In this paper I defend a unified approach to knowledge and understanding. Both are achievements due to cognitive abilities or skills. The difference between them is a difference of aspects. Knowledge emphasizes the successful aspect of an achievement and the exclusion of epistemic luck, whereas understanding emphasizes the agent's contribution in bringing about an achievement through the exercise of one's cognitive skills. Knowledge and understanding cannot be separated. I argue against the claim that understanding is distinct from knowledge because the (...) former is compatible with environmental luck. Achievements rule out environmental luck because abilities can be exercised only in their proper environment. I also reject the intellectualist claim that understanding requires the ability to explain what one intends to understand. The understanding of an item is reflected in our ability to solve cognitive tasks using that item. The more tasks one can deal with by using an item, the deeper is one’s understanding of that item. Being able to explain why a claim holds is not necessary for possessing understanding, even though it may be necessary for accomplishing some very specific tasks. Neither understanding nor knowledge require any kind of second-order cognition by default. (shrink)

This paper deals with two different problems in which infinity plays a central role. I first respond to a claim that infinity renders counting knowledge-level beliefs an infeasible approach to measuring and comparing how much we know. There are two methods of comparing sizes of infinite sets, using the one-to-one correspondence principle or the subset principle, and I argue that we should use the subset principle for measuring knowledge. I then turn to the normalizability and coarse tuning objections to fine-tuning (...) arguments for the existence of God or a multiverse. These objections center on the difficulty of talking about the epistemic probability of a physical constant falling within a finite life-permitting range when the possible range of that constant is infinite. Applying the lessons learned regarding infinity and the measurement of knowledge, I hope to blunt much of the force of these objections to fine-tuning arguments. (shrink)

Evolutionary reliabilism is the view that natural selection likely favoured reliable cognitive faculties in humans. While ER enjoys some plausibility, Stephen Stich and Alvin Plantinga have presented well-known challenges to the view. Their arguments rely on a common premiss; namely, that natural selection is indifferent to truth. This article shows that this premiss is both imprecise and too weak to support their conclusions and, therefore, that their challenges to ER fail.

Judging the warrant of conspiracy theories can be difficult, and often we rely upon what the experts tell us when it comes to assessing whether particular conspiracy theories ought to be believed. However, whereas there are recognised experts in the sciences, I argue that only are is no such associated expertise when it comes to the things we call `conspiracy theories,' but that the conspiracy theorist has good reason to be suspicious of the role of expert endorsements when it comes (...) to conspiracy theories and their rivals. The kind of expertise, then, we might associate with conspiracy theories is largely improvised—in that it lacks institutional features—and, I argue, ideally the product of a community of inquiry.

This is the second book by Baz that aims to show that a big chunk of contemporary philosophy is fundamentally misguided. His first book, When Words Are Called For: A Defense of Ordinary Language Philosophy (2012) adopted a therapeutic approach (in the Wittgensteinian style) to problems in contemporary epistemology, arguing that when properly thought through, the way philosophers talk about ‘knowing’ that something is the case ultimately does not make sense. Baz’s goal in his second book is less therapeutic and (...) more constructive: he aims to start a methodological revolution (in the Kuhnian sense)—to shake contemporary philosophers out of the unconscious habits of normal science and provoke them into making a radical change in the methods they use to do philosophy and the basic assumptions that motivate those methods.

Una de las bifurcaciones en el debate contemporáneo sobre la legitimidad de la democracia explora si ésta ofrece ventajas distintivamente epistémicas frente a otras alternativas políticas. Quienes defienden la tesis de la democracia epistémica afirman que la democracia es instrumentalmente superior o equiparable a otras formas de organización política en lo que concierne a la obtención de varios bienes epistémicos. En este ensayo presento dos (grupos de) argumentos a favor de la democracia epistémica, que se inspiran en resultados formales: el (...) teorema del jurado de Condorcet [TJC] y el teorema ‘diversidad supera habilidad’ [DSH]. Pese a su gran atractivo, sostengo que estos argumentos son incapaces de respaldar dicha tesis: no brindan razones para considerar que la democracia es epistémicamente superior (o equiparable) a algunas alternativas políticas no democráticas. En su lugar, sugiero que, sin requerir un cambio radical en nuestras formas de organización política, la epistemología democrática –el estudio de las ‘circunstancias epistémicas de la democracia’– puede ofrecer valiosas lecciones de sobre cómo optimizar, en nuestra situación, instituciones y procedimientos de toma de decisiones. Para ello, primero distingo entre varias maneras de evaluar procedimientos de toma de decisión colectiva. Argumento que, al considerarlos como formas de organización política, un factor importante en la evaluación de tales procedimientos involucra asuntos fácticos sobre los cuales puede aspirarse a obtener o promover algunos bienes epistémicos. En este contexto, presento algunos de los argumentos más importantes a favor de la democracia epistémica. A continuación, reúno algunas de las objeciones sobre la aplicabilidad de dichos argumentos y ofrezco razones independientes para dudar de que ofrezcan apoyo a la tesis de la democracia epistémica. Finalmente, defiendo que la epistemología democrática puede desempeñar un papel significativo en la legitimación de formas de organización colectiva que podrían denominarse ‘democráticas’. (shrink)

This paper critically examines Timothy Williamson’s claim that knowledge figures essentially in explanations of behavior. Since this claim implies that knowledge is causally efficacious in bringing about actions, it plays a key role in Williamson’s case for knowledge being a mental state. I first discuss a central example of Williamson, in which a burglar ransacks a house. I dispute Williamson’s claim that the best explanation of the burglar’s behavior invokes the burglar’s state of knowledge as he enters the house, by (...) arguing that there is a better explanation that only mentions the burglar’s beliefs. Since the reasons that explain the superiority of my proposed explanation generalize, I conclude that one does not have to invoke a subject’s state of knowledge to explain behavior. Nevertheless, Williamson’s explanation is superior to belief-based explanations if one only considers facts that obtain before the action takes place. In the final part of the paper, I argue that this fact does not help Williamson’s case for considering knowledge as a mental state. (shrink)

This paper briefly highlights a small part of the work being done by Indigenous groups in Canada to integrate science into their ways of knowing and living with nature. Special attention is given to a recent attempt by Mi'kmaw educators in Unama'ki (Cape Breton, Nova Scotia) to overcome suspicion of science among their youth by establishing an 'Integrative Science' (Toqwa'tu'kl Kjijitaqnn, or 'bringing our knowledges together') degree programme at Cape Breton University. The goal was to combine Indigenous and scientific knowledges (...) in a way that protects and empowers Mi'kmaw rights and lifeways. (shrink)

Duncan Pritchard argues that a feature that sets understanding-why apart from knowledge-why is that whereas (I) understanding-why is a kind of cognitive achievement in a strong sense, (II) knowledge-why is not such a kind. I argue that (I) is false and that (II) is true. (I) is false because understanding-why featuring rudimentary explanations and understanding-why concerning very simple causal connections are not cognitive achievements in a strong sense. Knowledge-why is not a kind of cognitive achievement in a strong sense for (...) the same reason knowledge-that is not. The latter thesis requires showing that having (p because q) information is not equivalent to having information about facts or principles that establish the explanatory connections between the phenomena in question. I make a positive case for this claim and defend it against objections. Based on this argument, I identify an alternative feature that sets understanding-why apart from knowledge-why: The minimal condition for understanding-why and knowledge-why with respect to their contents is not identical. Knowing why p merely requires information that some explanatorily relevant dependency obtains. Understanding why p additionally requires information about facts or principles that establish the explanatory connections between the phenomena in question. (shrink)
