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 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)

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.

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)

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)

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.

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.

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.

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)

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)

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 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)

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)

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)

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.

Background Informed consent is an integral component of good medical practice. Many researchers have investigated measures to improve the quality of informed consent, but it is not clear which techniques work best and why. To address this problem, we propose developing a core outcome set to evaluate interventions designed to improve the consent process for surgery in adult patients with capacity. Part of this process involves reviewing existing research that has reported what is important to patients and doctors in the (...) informed consent process. Methods This qualitative synthesis comprises four phases: identification of published papers and determining their relevance; appraisal of the quality of the papers; identification and summary of the key findings from each paper while determining the definitiveness of each finding against the primary data; comparison of key themes between papers such that findings are linked across studies. Results Searches of bibliographic databases returned 11,073 titles. Of these, 16 studies met the inclusion criteria. Studies were published between 1996 and 2016 and included a total of 367 patients and 74 health care providers. Thirteen studies collected data using in-depth interviews and constant comparison was the most common means of qualitative analysis. A total of 94 findings were extracted from the primary papers and divided into 17 categories and ultimately 6 synthesised findings related to: patient characteristics, knowledge, communication, the model patient, trust and decision making. Conclusions This qualitative meta-aggregation is the first to examine the issue of informed consent for surgery. It has revealed several outcomes deemed important to capture by patients and clinicians when evaluating the quality of a consent process. Some of these outcomes have not been examined previously in research comparing methods for informed consent. This review is an important step in the development of a COS to evaluate interventions designed to improve the consent process for surgery. Registration The study protocol was registered on the international prospective register for systematic reviews. (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.

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)

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.

Explaining phenomena is a primary goal of science. Consequently, it is unsurprising that gaining a proper understanding of the nature of explanation is an important goal of science education. In order to properly understand explanation, however, it is not enough to simply consider theories of the nature of explanation. Properly understanding explanation requires grasping the relation between explanation and understanding, as well as how explanations can lead to scientific knowledge. This article examines the nature of explanation, its relation to understanding, (...) and how explanations are used to generate scientific knowledge via inferences to the best explanation. Studying these features and applications of explanation not only provides insight into a concept that is important for science education in its own right, but also sheds light on an aspect of recent debates concerning the so-called consensus view of nature of science (NOS). Once the relation between explanation, understanding, and knowledge is clear, it becomes apparent that science is unified in important ways. Seeing this unification provides some support for thinking that there are general features of NOS of the sort proposed by the consensus view and that teaching about these general features of NOS should be a goal of science education.

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.

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.

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)

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. Despite the plausibility of this principle, Andrew Moon (2012) has recently argued that the principle is false. Moon’s argument consists of presenting what he takes to be a clear instance of knowledge and arguing that the subject in the case does not have this knowledge on the basis of any 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.

In Radical Skepticism & Epistemic Intuition Michael Bergmann attempts to overcome the threat of radical skepticism as it arises in several different forms. The key to Bergmann’s response to skepticism is his method of intuitionist particularism wherein we give our intuitions about particular beliefs being justified more weight than we do intuitions about the premises of arguments for skepticism. There are two general problems for Bergmann’s response to skepticism. First, he fails to accurately portray the key principle of the skeptical (...) argument. As a result, much of the apparent motivation for looking to intuitionist particularism as opposed to other responses to skepticism is merely apparent. Second, intuitionist particularism faces significant problems when it comes to the Problem of the Criterion and the resolution of conflicting intuitions. However, a related intuitionist method, one incorporating explanationism, may be able to deliver what intuitionist particularism promises while avoiding its problems. (shrink)

According to Phenomenal Conservatism (PC), if a subject S has an appearance that P, in the absence of defeaters, S has justification for believing P by virtue of her appearance's inherent justifying power. McCain and Moretti (2021) have argued that PC is affected by the problem of reflective awareness: if S becomes reflectively aware of an appearance, the appearance loses its inherent justifying power. This limits the explanatory power of PC and reduces its antisceptical bite. This paper provides a novel (...) argument to the same conclusion and contends that it does not apply to Phenomenal Explanationism, the appearance-based account of justification alternative to PC defended by McCain and Moretti (2021).

In this chapter I defend Explanationist Evidentialism, the theory developed and argued for in Evidentialism and Epistemic Justification, from the objections raised by Richard Fumerton, Jonathan Kvanvig, and Matthias Steup. Ultimately, I conclude that although each of these philosophers presents interesting challenges, none of the challenges succeed in undermining Explanationist Evidentialism. It remains a viable theory of epistemic justification.

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.

The first step in responding to the challenge of external world skepticism is to get clear on the structure of the skeptic’s argument. The most prominent varieties of skeptical arguments either rely on closure principles or underdetermination principles. The relationship between these two sorts of arguments is contentious. Some argue that these arguments can independently motivate skepticism. Others argue that they are really equivalent. I argue that although these two arguments are distinct, their independence is not as obvious as some (...) have thought. The fact that these arguments are not equivalent is important because skeptical arguments that appeal to underdetermination principles cannot be refuted by simply denying closure. So, the strategy for responding to skepticism offered by Nozick/Dretske does not seem an adequate solution. (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)

_ Source: _Page Count 13 A promising response to the threat of external world skepticism involves arguing that our commonsense view of the world best explains the sensory experiences that we have.

In a recent issue of this journal, Miloud Belkoniene challenges explanationist accounts of evidential support in two ways. First, he alleges that there are cases that show explanatory virtues are not linked to the truth of hypotheses. Second, he maintains that attempts to show that explanatoriness is relevant to evidential support because it adds to the resiliency (stability) of probability functions fail. I contest both of Belkoniene’s claims.

Phenomenal conservatism as developed by some philosophers faces a previously unnoticed problem. The problem stems from the fact that, as some develop the view, phenomenal conservatism holds that seemings alone justify—sensations have no justificatory impact. Given this, phenomenal conservatism faces a problem analogous to the isolation objection to coherentism. As foundationalists, supporters of phenomenal conservatism will want to allow that the isolation objection is effective against coherentism, and yet claim that a similar objection is not effective against their view. Unfortunately, (...) it appears that on most understandings of the nature of seemings phenomenal conservatism can only avoid its version of the isolation objection by sacrificing its internalist character.
