In this paper we distinguish between epistemic dilemmas, epistemic quasi-dilemmas, and quasi epistemic dilemmas. Our starting point is the commonsense position that S faces a genuine dilemma only when S must take one of two paths and both are bad. It’s the “must” that we think is key. Moral dilemmas arise because there are cases where S must perform A and S must perform B—where ‘must’ implies a moral duty—but S cannot do both. In such a situation, S is doomed (...) to violate a moral obligation. Analogously, S face’s a genuine epistemic dilemma only if she has an epistemic duty to believe that p and at the same time an epistemic duty to not believe that p (either because she has a duty to believe ~p or a duty to suspend judgment). We argue that such cases never arise because there is no epistemic duty to adopt a particular doxastic attitude towards any particular proposition (ever). Hence, there are no epistemic dilemmas. Nevertheless, one might suppose there are situations in which one’s evidence pulls in different directions without determining a uniquely justified doxastic attitude. Such epistemic quasi-dilemmas aren’t full-fledged dilemmas, but they are arguably close enough to pose a genuine problem for the believer. But we argue that there are no genuine epistemic quasi-dilemmas either: They are all resolvable in principle. Fans of dissonance will not be totally disappointed, however, since we argue that there may well be quasi-epistemic dilemmas. These are genuinely unwinnable situations in which one’s moral or pragmatic obligations to do epistemically-relevant things make incompatible demands. (shrink)

An evidentialist can be extreme about epistemic requirements in a couple of different ways. At the reductionist end of the spectrum are those who think our epistemic obligations are fully satisfied by the mere having of evidential fit—where having implies nothing about doing. Your beliefs ought to align with your evidence, in other words, but there’s nothing you’re obligated to do in order to get yourself into the epistemically optimal position. At the expansionist end of the spectrum are those who (...) think we ought to do more—epistemically-speaking—than just bring about a state of evidential fit. We ought to get more evidence, for instance, if it’s somehow relevant to our beliefs. Rather leery of extremists, we prefer a moderate account of epistemic obligation. It’s a conjunction of three theses: (1) We never have an epistemic duty to believe any particular proposition; (2) We’re epistemically obligated to reflect on our evidence in order to produce a state of evidential fit; (3) We’re never epistemically obligated to acquire any additional evidence. Our aim is to make these plausible. (shrink)

There are arguably moral, legal, and prudential constraints on behavior. But are there epistemic constraints on belief? Are there any requirements arising from intellectual considerations alone? This volume includes original essays written by top epistemologists that address this and closely related questions from a variety of new, sometimes unexpected, angles. It features a wide variety of positions, ranging from arguments for and against the existence of purely epistemic requirements, reductions of epistemic requirements to moral or prudential requirements, the biological foundations (...) of epistemic requirements, extensions of the scope of epistemic requirements to include such things as open- mindedness, eradication of implicit bias and interpersonal duties to object, to new applications such as epistemic requirements pertaining to storytelling, testimony, and fundamentalist beliefs. Anyone interested in the nature of responsibility, belief, or epistemic normativity will fi nd a range of useful arguments and fresh ideas in this cutting- edge anthology. (shrink)

It seems plausible that there can be “no win” moral situations in which no matter what one does one fails some moral obligation. Is there an epistemic analog to moral dilemmas? Are there epistemically dilemmatic situations—situations in which we are doomed to violate an epistemic requirement? If there are, when exactly do they arise and what can we learn from them? A team of top epistemologists address these and closely related questions from a variety of new, sometimes unexpected, angles. Anyone (...) interested in epistemic dilemmas, the nature of justification and evidential support, higher-order requirements, or suspension of judgment will find a range of useful arguments and fresh ideas in this cutting-edge anthology.

This volume presents new research on the epistemology of seemings. It features original essays by leading epistemologists on the nature and epistemic import of seemings and intuitions. Seemings and intuitions are often appealed to in philosophical theorizing. In fact, epistemological theories such as phenomenal conservatism and dogmatism give pride of place to seemings. Such views insist that seemings are of central importance to theories of epistemic justification. However, there are many questions about seemings that have yet to be answered satisfactorily. (...) What kinds of seemings are there? How do seemings justify? Are seemings connected to truth? Do they play a significant role in inquiry? The chapters in this volume offer a range of useful arguments and fresh ideas about seemings, the nature of justification and evidential support, intuitions, inquiry, and the nature of inference. Seemings: New Arguments, New Angles will be of interest to researchers and advanced students working in epistemology and philosophy of mind. (shrink)

Internalist theories of epistemic justification supposedly have trouble explaining what justifies beliefs that are both stored in memory and currently out of mind. This is the problem of stored beliefs. This chapter provides a preliminary defence of stored/dispositional appearances and suggests that they provide a straightforward solution to the problem of stored beliefs.

Background 300 million operations and procedures are performed annually across the world, all of which require a patient’s informed consent. No standardised measure of the consent process exists in current clinical practice. We aimed to define a core outcome set for informed consent for therapy. Methods The core outcome set was developed in accordance with a predefined research protocol and the Core OutcoMes in Effectiveness Trials methodology comprising systematic review, qualitative semi structured interviews, a modified Delphi process and consensus webinars (...) to ratify outcomes for inclusion in the final core outcome set.. Participants from all key stakeholder groups took part in the process, including patients and the public, healthcare practitioners and consent researchers. Results 36 outcome domains were synthesised through systematic review and organised into a consent taxonomy. 41 semi-structured interviews were performed with all consent stakeholders groups. 164 participants from all stakeholder groups across 8 countries completed Delphi Round 1 and 125 completed Round 2. 11 outcomes met the ‘consensus in’ criteria. 6 met ‘consensus in’ all stakeholder groups and were included directly in the final core outcome set. 5 remaining outcomes meeting ‘consensus in’ were ratified over two consensus webinars. 9 core outcomes were included in the final core outcome set: Satisfaction with the quality and amount of information, Patient feeling that there was a choice, Patient feeling that the decision to consent was their own, Confidence in the decision made, Satisfaction with communication, Trust in the clinician, Patient satisfaction with the consent process, Patient rated adequacy of time and opportunity to ask questions. Conclusion This international mixed-methods qualitative study is the first of its kind to define a core outcome set for informed consent for intervention. It defines what outcomes are of importance to key stakeholders in the consent process and is a forward step towards standardising future consent research. (shrink)

According to Roderick Chisholm, there are three ways of responding to the Problem of the Criterion and they all leave something to be desired. Michael DePaul, Paul Moser, and Earl Conee have each proposed variations of a fourth way of responding to this problem that rely on reflective equilibrium. We argue that these four options for responding to the Problem of the Criterion leave one with a tough choice: accept one of the three that Chisholm describes or DePaul’s reflective equilibrium (...) approach and beg the question or accept a reflective equilibrium response of the sort Conee and Moser propose and embrace epistemic circularity.

Looking back, the moral panic that precipitated the decimation of horror comics in the 1950s seems quaint, yet concerns about the psychological impact of violent media on consumers have never disappeared. In this article, I outline a particular type of psychological impact we ought to take seriously when evaluating the moral status of entertainment. I then consider (a) ways in which comics seem immune from claims that they create this kind of impact for their readers, as well as (b) ways (...) in which we might think that comics generate special instances of moral danger for readers.

Evidentialism is a popular theory of epistemic justification, yet, as early proponents of the theory Earl Conee and Richard Feldman admit, there are many elements that must be developed before Evidentialism can provide a full account of epistemic justification, or well-founded belief. It is the aim of this book to provide the details that are lacking; here McCain moves past Evidentialism as a mere schema by putting forward and defending a full-fledged theory of epistemic justification. In this book (...) class='Hi'>McCain offers novel approaches to several elements of well-founded belief. Key among these are an original account of what it takes to have information as evidence, an account of epistemic support in terms of explanation, and a causal account of the basing relation that is far superior to previous accounts. The result is a fully developed Evidentialist account of well-founded belief. (shrink)

Scientific knowledge is the most solid and robust kind of knowledge that humans have because of its inherent self-correcting character. Nevertheless, anti-evolutionists, climate denialists, and anti-vaxxers, among others, question some of the best-established scientific findings, making claims unsupported by empirical evidence. A common aspect of these claims is reference to the uncertainties of science concerning evolution, climate change, vaccination, and so on. This is inaccurate: whereas the broad picture is clear, there will always exist uncertainties about the details of the (...) respective phenomena. This book shows that uncertainty is an inherent feature of science that does not devalue it. In contrast, uncertainty advances science because it motivates further research. This is the first book on this topic that draws on philosophy of science to explain what uncertainty in science is and how it makes science advance. It contrasts evolution, climate change, and vaccination, where the uncertainties are exaggerated, and genetic testing and forensic science, where the uncertainties are usually overlooked. The goal is to discuss the scientific, psychological, and philosophical aspects of uncertainty in order to explain what it really is, what kinds of problems it actually poses, and why in the end it makes science advance. Contrary to public representations of scientific findings and conclusions that produce an intuitive but distorted view of science as certain, people need to understand and learn to live with uncertainty in science. This book is intended for anyone who wants to get a clear view of the nature of science. (shrink)

Scott Yenor argues that David Hume's reputation as a skeptic is greatly exaggerated. In David Hume's Humanity, Yenor shows how Hume's skepticism is a moment leading Hume to defend a philosophy that is grounded in the inescapable assumptions of common life. Humane virtues reflect the proper reaction to the complex mixture of human faculties that define the human condition. These gentle virtues best find their home in the modern commercial republic, of which England is the leading example. Hume's defense (...) of both common life philosophy and humanity are, however, flawed by his secretly dogmatic assumptions about the nature of history and his Enlightened approach to religious teachings and psychology. This study makes the case for Hume's manner of grounding philosophy in common life is essential to any reinvigoration of the humanities. It ultimately holds that Hume's practice of that philosophy is seriously flawed, but that a more philosophic philosophy of common life is available. (shrink)

Phenomenal Conservatism (the view that an appearance that p gives one prima facie justification for believing that p) is a promising, and popular, internalist theory of epistemic justification. Despite its popularity, it faces numerous objections and challenges. For instance, epistemologists have argued that Phenomenal Conservatism is incompatible with Bayesianism, is afflicted by bootstrapping and cognitive penetration problems, does not guarantee that epistemic justification is a stable property, does not provide an account of defeat, and is not a complete theory of (...) epistemic justification. This book shows that Phenomenal Conservatism is actually immune to some of these problems, though not all of them. Accordingly, it explores the prospects of integrating Phenomenal Conservatism with Explanationism (the view that epistemic justification is a matter of explanatory relations between one’s evidence and propositions supported by that evidence). The resulting theory, Phenomenal Explanationism, has advantages over Phenomenal Conservatism and Explanationism taken on their own. Phenomenal Explanationism is a highly unified, comprehensive internalist theory of epistemic justification that delivers on the promises of Phenomenal Conservatism while avoiding its pitfalls.

Memory skepticism denies our memory beliefs could have any notable epistemic good. One route to memory skepticism is to challenge memory’s epistemic trustworthiness, that is, its functioning in a way necessary for it to provide epistemic justification. In this paper we develop and respond to this challenge. It could threaten memory in such a way that we altogether lack doxastic attitudes. If it threatens memory in this way, then the challenge is importantly self-defeating. If it does not threaten memory in (...) this way, then the challenge leaves a foundation for an inference to the best explanation response, one we articulate and support. (shrink)

It is commonplace to distinguish between propositional justification (having good reasons for believing p) and doxastic justification (believing p on the basis of those good reasons).One necessary requirement for bridging the gap between S’s merely having propositional justification that p and S’s having doxastic justification that p is that S base her belief that p on her reasons (propositional justification).A plausible suggestion for what it takes for S’s belief to be based on her reasons is that her reasons must contribute (...) causally to S’s having that belief. Though this suggestion is plausible, causal accounts of the basing relation that have been proposed have not fared well. In particular, cases involving causal deviancy and cases involving over-determination have posed serious problems for causal accounts of the basing relation. Although previous causal accounts of the basing relation seem to fall before these problems, it is possible to construct an acceptable causal account of the basing relation. That is, it is possible to construct a causal account of the basing relation that not only fits our intuitions about doxastic justification in general, but also is not susceptible to the problems posed by causal deviancy and causal over-determination. The interventionist account of causation provides the tools for constructing such an account. My aim is to make use of the insights of the interventionist account of causation to develop and defend an adequate causal account of the basing relation. (shrink)

Warrior cultures throughout history have developed unique codes that restrict their behavior and set them apart from the rest of society. But what possible reason could a warrior have for accepting such restraints? Why should those whose profession can force them into hellish kill-or-be-killed conditions care about such lofty concepts as honor, courage, nobility, duty, and sacrifice? And why should it matter so much to the warriors themselves that they be something more than mere murderers? The Code of the Warrior (...) tackles these timely issues and takes the reader on a tour of warrior cultures and their values, from the ancient Greeks and Romans to the 'barbaric' Vikings and Celts, from legendary chivalric knights to Native American tribesmen, from Chinese warrior monks pursuing enlightenment to Japanese samurai practicing death. Drawing these rich traditions up to the present, the author quests for a code for the warriors of today, as they do battle in asymmetric conflicts against unconventional forces and the scourge of global terrorism.

William Roche and Elliott Sober argue that explanatoriness is evidentially irrelevant. This conclusion is surprising since it conflicts with a plausible assumption—the fact that a hypothesis best explains a given set of data is evidence that the hypothesis is true. We argue that Roche and Sober's screening-off argument fails to account for a key aspect of evidential strength: the weight of a body of evidence. The weight of a body of evidence affects the resiliency of probabilities in the light of (...) new evidence. Thus, Roche and Sober are mistaken. Explanatoriness is evidentially relevant. (shrink)

This chapter discusses the roles of ether and electrons in relativity theory. One of the most radical moves made by Albert Einstein was to dismiss the ether from electrodynamics. His fellow physicists felt challenged by Einstein’s view, and they came up with a variety of responses, ranging from enthusiastic approval, to dismissive rejection. Among the naysayers were the electron theorists, who were unanimous in their affirmation of the ether, even if they agreed with other aspects of Einstein’s theory of relativity. (...) The eventual success of the latter theory (circa 1911) owed much to Hermann Minkowski’s idea of four-dimensional spacetime, which was portrayed as a conceptual substitute of sorts for the ether.

Although several important methodologies implicitly assume the truth of epistemic conservatism, the view that holding a belief confers some measure of justification on the belief, recent criticisms have led some to conclude that epistemic conservatism is an implausible view. That conclusion is mistaken. In this article, I propose a new formulation of epistemic conservatism that is not susceptible to the criticisms leveled at earlier formulations of epistemic conservatism. In addition to withstanding these criticisms, this formulation of epistemic conservatism has several (...) benefits. First, this formulation has the benefits of earlier formulations of epistemic conservatism, that is to say it makes sense of our intuitions about justification in regard to both memory beliefs and beliefs for which we have forgotten our evidence. Second, it provides a good way of responding to the skeptic’s challenge concerning the possibility of possessing knowledge of the external world posed by the Alternative Hypotheses argument. Third, it provides responses to both forms of a new skeptical problem plaguing basic knowledge structure theories, the Problem of Easy Knowledge formulated by Stewart Cohen. I argue that given the many benefits of this formulation of epistemic conservatism and the fact that it is not vulnerable to the criticisms that undermine earlier formulations of epistemic conservatism, this formulation of epistemic conservatism is a plausible view to maintain.

Explanationists about epistemic justification hold that justification depends upon explanatory considerations. After a bit of a lull, there has recently been a resurgence of defenses of such views. Despite the plausibility of these defenses, explanationism still faces challenges. Recently, T. Ryan Byerly and Kraig Martin have argued that explanationist views fail to provide either necessary or sufficient conditions for epistemic justification. I argue that Byerly and Martin are mistaken on both accounts.

This volume explores evidentialism, a major theory of epistemic justification. It contains more than 20 papers that examine its nuances, its challenges, as well as its future directions. Written by leading and up-and-coming epistemologists, the papers cover a wide array of topics related to evidentialism. The contributors present both sides of the theory: some are advocates of evidentialism, while others are critics. This provides readers with a comprehensive, and cutting-edge, understanding of this epistemic theory. Overall, the book is organized into (...) six parts: The Nature of Evidence, Understanding Evidentialism, Problems for Evidentialism, Evidentialism and Social Epistemology, New Directions for Evidentialism, and Explanationist Evidentialism. Readers will find insightful discussion on such issues as the ontology of evidence, phenomenal dogmatism, how experiences yield evidence, the new evil demon problem, probability, norms of credibility, intellectual virtues, wisdom, epistemic justification, and more. This title provides authoritative coverage of evidentialism, from the latest developments to the most recent philosophical criticisms. It will appeal to researchers and graduate students searching for more information on this prominent epistemological theory. (shrink)

This ambitious, interdisciplinary book seeks to explain the origins of religion using our knowledge of the evolution of cognition. A cognitive anthropologist and psychologist, Scott Atran argues that religion is a by-product of human evolution just as the cognitive intervention, cultural selection, and historical survival of religion is an accommodation of certain existential and moral elements that have evolved in the human condition.

This book offers a comprehensive and accessible introduction to the epistemology of science. It not only introduces readers to the general epistemological discussion of the nature of knowledge, but also provides key insights into the particular nuances of scientific knowledge. No prior knowledge of philosophy or science is assumed by The Nature of Scientific Knowledge. Nevertheless, the reader is taken on a journey through several core concepts of epistemology and philosophy of science that not only explores the characteristics of the (...) scientific knowledge of individuals but also the way that the development of scientific knowledge is a particularly social endeavor. The topics covered in this book are of keen interest to students of epistemology and philosophy of science as well as science educators interested in the nature of scientific knowledge. In fact, as a result of its clear and engaging approach to understanding scientific knowledge The Nature of Scientific Knowledge is a book that anyone interested in scientific knowledge, knowledge in general, and any of a myriad of related concepts would be well advised to study closely.

Twenty philosophers offer new essays examining the form of reasoning known as inference to the best explanation - widely used in science and in our everyday lives, yet still controversial. Best Explanations represents the state of the art when it comes to understanding, criticizing, and defending this form of reasoning.

Explanationism is a plausible view of epistemic justification according to which justification is a matter of explanatory considerations. Despite its plausibility, explanationism is not without its critics. In a recent issue of this journal T. Ryan Byerly and Kraig Martin have charged that explanationism fails to provide necessary or sufficient conditions for epistemic justification. In this article I examine Byerly and Martin’s arguments and explain where they go wrong.

James Woodward’s Making Things Happen presents the most fully developed version of a manipulability theory of causation. Although the ‘interventionist’account of causation that Woodward defends in Making Things Happen has many admirable qualities, Michael Strevens argues that it has a fatal flaw. Strevens maintains that Woodward’s interventionist account of causation renders facts about causation relative to an individual’s perspective. In response to this charge, Woodward claims that although on his account X might be a relativized cause of Y relative to (...) some perspective, this does not lead to the problematic relativity that Strevens claims. Roughly, Woodward argues this is so because if X is a relativized cause of Y with respect to some perspective, then X is a cause of Y simpliciter. So, the truth of whether X is a cause of Y is not relative to one’s perspective. Strevens counters by arguing that Woodward’s response fails because relativized causation is not monotonic. In this paper I argue that Strevens’ argument that relativized causation is not monotonic is unsound. (shrink)

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a regress (...) of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem. (shrink)

Epistemologists have a special fondness for David Hume. Even Kant-obsessed a priorists admire the honesty, directness and elegance of his thinking. He is the Mozart of analytic philosophy rather than the Bach. Sparkling ideas, icy clarity and popular delivery make his writings the standard for good philosophy. 'Try to think like Hume' is pretty decent advice. But is that his only use today—to be emulated in style and approach? This volume is a collective 'no'. A team of top epistemologists and (...) historians join forces to demonstrate the relevance of Humean ideas to the most current questions and debates. Hume dribbles into the following themes, much to the advantage of each: knowledge, belief, inquiry and suspension, reason and reasons, scepticism, hinge epistemology, naturalized epistemology, the ethics of belief and moral epistemology, virtue and vice epistemology, the epistemology of testimony. Epistemologists who discount history and historians who halt at 1950 should gallop to this volume and start reading. Neither perspective will survive. (shrink)

The law of gravitational attraction is a window on three formal approaches to laws of nature based on Lorentz-invariance: Poincaré’s four-dimensional vector space (1906), Minkowski’s matrix calculus and spacetime geometry (1908), and Sommerfeld’s 4-vector algebra (1910). In virtue of a common appeal to 4-vectors for the characterization of gravitational attraction, these three contributions track the emergence and early development of four-dimensional physics.

Ernest Sosa has recently presented three challenges for evidentialism. The challenges concern what is required for epistemically justified judging and suspending of judgment. The aim of this article is to respond to these challenges on behalf of the evidentialist. Importantly, responding to Sosa's challenges requires giving substance to the idea of appreciating what one's evidence supports. This idea has been mentioned by prominent evidentialists but not given adequate development. Hence, this article marks a significant move forward in the understanding of (...) evidentialism as well as a defense of the theory from Sosa's prima facie serious objections. (shrink)

In their most recent co-authored work, Conee and Feldman (2008) suggest that epistemic support should be understood in terms of best explanations. Although this suggestion is plausible, Conee and Feldman admit that they have not provided the necessary details for a complete account of epistemic support. This article offers an explanationist account of epistemic support of the kind that Conee and Feldman suggest. It is argued that this account of epistemic support yields the intuitively correct results in a wide variety (...) of cases. Further, this explanationist account of epistemic support is not susceptible to objections that Lehrer (1974) and Goldman (2011) have raised for similar accounts of epistemic support. (shrink)

Phenomenal conservatism is a popular theory of epistemic justification. Despite its popularity and the fact that some think that phenomenal conservatism can provide a complete account of justification, it faces several challenges. Among these challenges are the need to provide accounts of defeaters and inferential justification. Fortunately, there is hope for phenomenal conservatism. Explanationism, the view on which justification is a matter of explanatory considerations, can help phenomenal conservatism with both of these challenges. The resulting view is one that respects (...) the internalist character of phenomenal conservatism and its motivating intuitions while providing an intuitive and elegant account of both inferential justification and the justificatory impact of defeaters.

Earl Conee and Richard Feldman have argued that epistemic support should be understood in terms of explanatory considerations. Very roughly, they hold that one’s evidence supports a given proposition when that proposition is part of the best explanation of one’s evidence. This proposal is attractive, but T. Ryan Byerly has recently argued that it is false. Byerly claims that such explanationist accounts of epistemic support cannot account for the fact that one’s evidence can support propositions about the future. Although Byerly (...) presents an interesting challenge, his argument is problematic and, ultimately, unconvincing. (shrink)

This book analyses the straw man fallacy and its deployment in philosophical reasoning. While commonly invoked in both academic dialogue and public discourse, it has not until now received the attention it deserves as a rhetorical device. Scott Aikin and John Casey propose that straw manning essentially consists in expressing distorted representations of one's critical interlocutor. To this end, the straw man comprises three dialectical forms, and not only the one that is usually suggested: the straw man, the weak (...) man and the hollow man. Moreover, they demonstrate that straw manning is unique among fallacies as it has no particular logical form in itself, because it is an instance of inappropriate meta-argument, or argument about arguments. They discuss the importance of the onlooking audience to the successful deployment of the straw man, reasoning that the existence of an audience complicates the dialectical boundaries of argument. Providing a lively, provocative and thorough analysis of the straw man fallacy, this book will appeal to postgraduates and researchers alike, working in a range of fields including fallacies, rhetoric, argumentation theory and informal logic.

The “problem of forgotten evidence” is a common objection to evidentialist theories of epistemic justification. This objection is motivated by cases where someone forms a belief on the basis of supporting evidence and then later forgets this evidence while retaining the belief. Critics of evidentialist theories argue that in some of these cases the person's belief remains justified. So, these critics claim that one can have a justified belief that is not supported by any evidence the subject possesses. I argue (...) that these critics are mistaken. (shrink)

Inspired by a debate between Noam Chomsky and Jean Piaget, this work traces the development of natural history from Aristotle to Darwin, and demonstrates how the science of plants and animals has emerged from the common conceptions of folkbiology.

Predictivism, the thesis that all things being equal a hypothesis that predicts a piece of evidence is better supported by that evidence than a hypothesis that only accommodates that evidence, comes in strong and weak forms. Interestingly, weak predictivism, which is widely accepted, can be used to formulate a persuasive argument against some forms of external world scepticism. In this article I formulate this predictivist argument and I explain why it deserves serious consideration despite the fact that it only succeeds (...) as a response to some forms of external world scepticism.

The Evidence Thesis is the intuitively plausible principle that in order to know that p one must base her belief that p on adequate evidence.

I argue that Moon’s example (...) fails to be a genuine counterexample to the Evidence Thesis. (shrink)

Although inference to the best explanation is ubiquitous in science and our everyday lives, there are numerous objections to the viability of IBE. Many of these objections have been thoroughly discussed, however, at least one objection to IBE has not received adequate treatment. We term this objection the “Disjunction Objection”. This objection challenges IBE on the grounds that it seems that even if H is the best explanation, it could be that the disjunction of its rivals is more likely to (...) be true. As a result, IBE appears to license accepting a hypothesis that is more likely than not to be false. Despite these initial appearances, we argue that the Disjunction Objection fails to impugn IBE.

_ Source: _Page Count 14 Jonathan Vogel has argued in support of an explanationist response to skepticism in several works. Central to this explanationist response is the fact that our non-skeptical view of the world is a better explanation of our experiences than its skeptical rivals. Despite the plausibility of this response to skepticism, it is not without its critics. Recently, Matthew Gifford has argued that Vogel’s response has problems on two fronts. First, Gifford argues that Vogel’s strategy for showing (...) that the rwh is a better explanation than its skeptical rivals fails. Second, he argues that if Vogel’s strategy does succeed, then it accomplishes too much—it removes skeptical doubts when it should not. I argue that Gifford is mistaken on both accounts. (shrink)

Evolutionary theory is a paradigmatic example of a well-supported scientific theory. In this chapter we consider a number of objections to evolutionary theory, and show how responding to these objections reveals aspects of the way in which scientific theories are supported by evidence. Teaching these objections can therefore serve two pedagogical aims: students can learn the right way to respond to some popular arguments against evolutionary theory, and they can learn some basic features of the structure of scientific theories and (...) evidence.
