Ethical theory often starts with our intuitions about particular cases and tries to uncover the principles that are implicit in them; work on the ‘trolley problem’ is a paradigmatic example of this approach. But ethicists are no longer the only ones chasing trolleys. In recent years, psychologists and neuroscientists have also turned to study our moral intuitions and what underlies them. The relation between these two inquiries, which investigate similar examples and intuitions, and sometimes produce parallel results, is puzzling. Does (...) it matter to ethics whether its armchair conclusions match the psychologists’ findings? I argue that reflection on this question exposes psychological presuppositions implicit in armchair ethical theorising. When these presuppositions are made explicit, it becomes clear that empirical evidence can (and should) play a positive role in ethical theorising. Unlike recent assaults on the armchair, the argument I develop is not driven by a naturalist agenda, or meant to cast doubt on the reliability of our moral intuitions; on the contrary, it is even compatible with non-naturalism, and takes the reliability of intuition as its premise. The argument is rather that if our moral intuitions are reliable, then psychological evidence should play a surprisingly significant role in the justification of moral principles. (shrink)

Understanding has received growing interest from epistemologists in recent years, but no consensus regarding its epistemic properties has yet been reached. This paper extracts, but also rejects, candidates of epistemic properties for construing an epistemological model of understanding from the writings of epistemologists participating in the current discussion surrounding that state. On the basis of these results, a suggestion is put forward according to which understanding is a non-basic epistemic state of warrant rather than knowledge. It is argued that this (...) move provides a satisfactory conciliatory answer to the central question whether understanding is a factive epistemic state. Some differences between understanding and knowledge are recorded along the way: for instance, that in contrast to knowledge, understanding does not require belief and that, even though neither knowledge nor understanding iterates, so that a subject can both know without knowing that she knows, as well as understanding without understanding that she understands, the reasons for the failure is different. (shrink)

In the current discussion on epistemic value, several philosophers argue that understanding enjoys higher epistemological significance and epistemic value than knowledge—the epistemic state the epistemological tradition has been preoccupied with. By noting a tension between the necessary conditions for understanding in the perhaps most prominent of these philosophers, Jonathan Kvanvig, this paper disputes the higher epistemological relevance of understanding. At the end, on the basis of the results of the previous sections, some alternative comparative contrasts between knowledge and understanding are (...) briefly explored, including one in which an analogue to the KK-principle for knowledge, the “UU-principle”, does not hold for a different reason than that for which the former principle fails. (shrink)

This paper investigates some epistemic properties that distinguish understanding from knowledge. In particular, the focus is on how to spell out the notion of grasping the relationships between propositions that constitute objectual understanding: what kind of epistemic access is required for grasping to occur and to what extent is the act of grasping voluntary? A modest form of access is suggested as an answer to the first question and a largely negative answer to the second. The worry that my suggestion (...) is too permissive in crediting subjects with understanding is addressed. The results are then finally briefly contrasted to Ernest Sosa’s notion of knowing full well where one contrast precisely concerns the voluntary character of the respective epistemic states.

A sensible epistemologist may not see how she could know that she is not a brain in a vat ; but she doesn’t panic. She sticks with her empirical beliefs, and as that requires, believes that she is not a BIV. (She does not inferentially base her belief that she is not a BIV on her empirical knowledge—she rejects that ‘Moorean’ response to skepticism.) Drawing on the psychological literature on metacognition, I describe a mechanism that’s plausibly responsible for a sensible (...) epistemologist coming to believe she is not a BIV. I propose she thereby knows that she is not a BIV. The particular belief-forming mechanism employed explains why she overlooks this account of how she knows she is not a BIV, making it seem that there is no way for her to know it. I argue this proposal satisfactorily resolves the skeptical puzzle. (shrink)

This paper introduces and defends the paradigm response to external world skepticism. To understand it, consider an analogy. One of the hallmarks of being a bird is an ability to fly. A penguin lacks this hallmark and thus fails to be a paradigm bird. Likewise, there are various hallmarks of knowledge. Some of your external world beliefs lack some of these hallmarks, and thus fail to be paradigm cases of knowledge. Just as the inability of penguins to fly doesn’t prevent (...) them from being birds, likewise the lack of these hallmarks doesn’t prevent your beliefs from being knowledge. It just prevents them from being paradigm cases thereof. (shrink)

ABSTRACT: According to a traditional account, understanding why X occurred is equivalent to knowing that X was caused by Y. This paper defends the account against a major objection, viz., knowing-that is not sufficient for understanding-why, for understanding-why requires a kind of grasp while knowledge-that does not. I discuss two accounts of grasp in recent literature and argue that if either is true, then knowing that X was caused by Y entails at least a rudimentary understanding of why X occurred. (...) If my defense is successful, it would cast doubt on an influential account of the epistemic value of understanding. (shrink)

There are three widely held beliefs among epistemologists: (1) the goal of inquiry is truth or something that entails truth; (2) epistemology aims for a reflectively stable theory via reflective equilibrium; (3) epistemology is a kind of inquiry. I argue that accepting (1) and (2) entails denying (3). This is a problem especially for the philosophers (e.g. Duncan Pritchard and Alvin Goldman) who accept both (1) and (2), for in order to be consistent, they must reject (3). The tension is (...) not restricted to epistemology. A similar tension also exists in the area of moral philosophy. The tension can be generalized. If one believes that the goal of inquiry is truth or something that entails truth and that philosophy aims for a reflectively stable theory via reflective equilibrium, she must deny that philosophy is a kind of inquiry.

According to the extended mind thesis, cognitive processes are not confined to the nervous system but can extend beyond skin and skull to notebooks, iPhones, computers and such. The extended mind thesis is a metaphysical thesis about the material basis of our cognition. As such, whether the thesis is true can have implications for epistemological issues. Carter has recently argued that safety-based theories of knowledge are in tension with the extended mind hypothesis, since the safety condition implies that there is (...) an epistemic difference between subjects who form their beliefs via their biological capacities and between subjects who have extended their cognition. Kelp, on the other hand, has argued that a safety-based theory of knowledge can be correct only if the extended mind thesis is true. While these claims are not logically inconsistent, they do leave the safety theorist in an uncomfortable position. I will argue that safety-based theories of knowledge are not hostage to the truth of the extended mind thesis, and that once the safety condition is properly understood it is not in tension with the extended mind thesis.

Knowledge defeat occurs when a subject knows that _p_, gains a defeater for her belief, and thereby loses her knowledge without necessarily losing her belief. It’s far from obvious that externalists can accommodate putative cases of knowledge defeat since a belief that satisfies the externalist conditions for knowledge can satisfy those conditions even if the subject later gains a defeater for her belief. I’ll argue that virtue reliabilists can accommodate defeat intuitions via a new kind of error theory. I argue (...) that in cases where the subject holds dogmatically onto her belief in the face of an apparent defeater, her belief never qualified as knowledge, since the belief was not gained via an exercise of her epistemic virtues. In cases where the subject suspends her judgment upon receiving the putative defeater her original belief might have qualified as knowledge, but crucially, in such cases knowledge is lost due to loss of belief, rather than due to the epistemic force of the defeater. Therefore, knowledge defeat isn’t a genuine phenomenon even though there are no cases where a subject knows what she originally believed after receiving the putative defeater. (shrink)

We may usefully distinguish between one’s having fallible knowledge and having a fallibilist stance on some of one’s knowledge. A fallibilist stance could include a concessive knowledge-attribution. But it might also include a questioning knowledge-attribution. Attending to the idea of a QKA leads to a distinction between what we may call closed knowledge that p and open knowledge that p. All of this moves us beyond Elgin’s classic tale of the epistemic capacities of Holmes and of Watson, and towards a (...) way of resolving Kripke’s puzzle about dogmatism and knowing. (shrink)

In What Philosophers Know, Gary Gutting provides an epistemology of philosophical reflection. This paper focuses on the roles that various intuitive inputs are said to play in philosophical thought. Gutting argues that philosophers are defeasibly entitled to believe some of these, prior to the outcome of the philosophical reflection, and that they then rightly serve as significant (again defeasible) anchors on reflection. This paper develops a view of epistemic entitlement and applies it to argue that many prephilosophical convictions of the (...) kind Gutting discusses would be just the sort of belief for which entitlement would plausibly be defeated from the start. They then could not properly play the role in philosophical reflection that Gutting envisions for them. (shrink)

What is the relationship between virtue and safety? This paper argues that Sosa’s positions in A Virtue Epistemology and in Judgment and Agency regarding this question are, despite appearances to the contrary, in fact consistent. Moreover, Sosa’s position there is well motivated—his Virtue Epistemology explains why knowledge should require apt belief, and why aptness should imply safety. Finally, the paper shows how two kinds of safety are importantly related to Sosa’s response to the Pyrrhonian Problematic. Specifically, reflections on the modal (...) profiles of first-order and second-order safety allow us to answer two prominent objections to Sosa’s position. (shrink)

In this paper we give reasons to think that reflective epistemic subjects cannot possess mere animal knowledge. To do so we bring together literature on defeat and higher-order evidence with literature on the distinction between animal knowledge and reflective knowledge. We then defend our argument from a series of possible objections.

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic rationality is (...) sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

Ernest Sosa has made and continues to make major contributions to a wide variety of topics in epistemology. In this paper I discuss some of his core ideas about the nature of knowledge and scepticism. I start with a discussion of the safety account of knowledge – a view he has championed and further developed over the years. I continue with some questions concerning the role of the concept of an epistemic virtue for our understanding of knowledge. Safety and virtue (...) hang very closely together for Sosa. All this easily leads to some thoughts on epistemic scepticism and on Sosa's stance on this. (shrink)

Our beliefs utilize various sources: perception, memory, induction, etc. We trust these sources to provide reliable information about the world around us. My dissertation investigates how this trust could be justified. Chapter one introduces background material. I argue that justification rather than knowledge is of primary epistemological importance, discuss the internalism/externalism debate, and introduce an evidentialist thesis that provides a starting point/framework for epistemological theorizing. Chapter two introduces a puzzle concerning justification. Can a belief source provide justification absent prior justification (...) for believing it's reliable? Any answer appears to either make justifying the reliability of a source intellectually unsatisfying or all together impossible. Chapter three considers and rejects a plethora of proposed solutions to our puzzle. Investigating these solutions illustrates the need to further investigate evidence, evidence possession, and evidential support. Chapter four discusses the metaphysics of evidence. I argue that evidence always consists of a set of facts and that fact-proposition pairs stand in confirmation relations isomorphic to those holding between pairs of propositions. Chapter five argues that justification requires what I call actually connected possession of supporting evidence: a subject must be aware of supporting evidence and of the support relation itself. Chapter six argues that the relation constitutive of a set of facts being justificatory evidence is a sui generis and irreducible relation that is knowable a priori. Chapter seven begins by showing how Richard Fumerton's acquaintance theory meets the constraints on a theory of justification laid down in previous chapters. I modify the theory so as to: make room for fallible foundational justification, and allow inferential justification absent higher-order beliefs about evidential connections. Chapter eight applies the developed theory of justification to our initial puzzle. I show how my modified acquaintance theory is in a unique position to vindicate the idea that necessarily a source provides a person with justification only if she is aware of evidence for the reliability of that source. However, this awareness of evidence for a source's reliability falls short of a justified belief and thereby avoids impalement from our dilemma's skeptical horn. (shrink)

Regulative virtue epistemology argues that intellectual virtues can adjust and guide one’s epistemic actions as well as improve on the quality of the epistemic actions. For regulative virtue epistemologists, intellectual virtues can be cultivated to a higher degree; when the quality of intellectual virtue is better, the resulting quality of epistemic action is better. The intellectual virtues that regulative epistemologists talk about are character virtues (such as intellectual courage and open-mindedness) rather than faculty virtues (such as sight and hearing), since (...) they don’t think that faculty virtues could be cultivated. This article refers to Xunzi’s philosophy, explaining how a regulative faculty-based virtue epistemology is possible. If this explanation works, on the one hand, a new branch of contemporary virtue epistemology is shown, and, on the other hand, a clear theoretical framework of Xunzi’s epistemology is constructed.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

A new way to transpose the virtue epistemologist’s ‘knowledge = apt belief’ template to the collective level, as a thesis about group knowledge, is developed. In particular, it is shown how specifically judgmental belief can be realised at the collective level in a way that is structurally analogous, on a telic theory of epistemic normativity (e.g., Sosa 2020), to how it is realised at the individual level—viz., through a (collective) intentional attempt to get it right aptly (whether p) by alethically (...) affirming that p. An advantage of the proposal developed is that it is shown to be compatible with competing views—viz., joint acceptance accounts and social-distributive accounts—of how group members must interact in order to materially realise a group belief. I conclude by showing how the proposed judgment-focused collective (telic) virtue epistemology has important advantages over a rival version of collective virtue epistemology defended in recent work by Jesper Kallestrup (2016).

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)

Traditional accounts of justification can be characterized as trying to analyze justification in such a way that having a justified belief brings with it assurance of truth. The internalist offers a demanding requirement on justification: one's having a justified belief requires that one see what the belief has going for it. Externalists worry that the internalist's narrow conception of justification will lead to unacceptably radical and implausible skepticism. According to the externalist, one need not know what a belief has going (...) for it in order for that belief to be justified. Externalism, though, comes with its own problems. Ernest Sosa has attempted to bridge the divide between internalism and externalism by pairing the strengths of internalism with the strengths of externalism. Sosa distinguishes two kinds of knowledge: animal knowledge that is essentially externalist in character and reflective knowledge that is intended to capture our best intellectual procedure in regards to knowledge. On Sosa's view, one gains reflective knowledge by building upon animal knowledge. As a result, Sosa's view seems to illustrate a bottom-up approach to the analysis of knowledge : reflective knowledge is the result of animal knowledge and some other epistemic factor. My project, in contrast to Sosa's, is to argue that one should start with an account of ideal justification and then proceed by loosening the standards on ideal justification in an effort to develop the possibility of non- ideal kinds of justification. The view that I will develop will adopt Sosa's strategy of distinguishing kinds of knowledge, but will result in a top-down approach to the analysis of justification. Instead of starting with an undemanding standard and layer levels on top, I will start with an ideal standard and strip layers away. I will also argue that my view has some important advantages over Sosa's. Not only does Sosa's view seem to run into many of the problems that threaten externalism, but his view is incapable of offering the kind of assurance that the internalist is after. The view I develop will maintain the internalist's interest in assurance while also providing a response to some of the skeptical problems that have plagued internalists. If my project is successful, then, even if the justification that results in many of the cases I will be exploring is not ideal, we can use these conceptions of justification to help explicate how one might have justified beliefs about a great number of things. The essentially internalist account that I have offered will not only illustrate a serious approach to dealing with skepticism, but it will also capture how many of our commonsensically justified beliefs are in fact justified.

In this work, we will try to state the opposition between two approaches to the problem of the overall reliability of human knowing capacities, and a possible solution to that conflict. On the one hand, as we will point out, there exist a number of approaches that fall under the broad term of “evolutionary reliabilism” and according to which the reasons that we have for believing in the reliability of human cognition are empirical in character. Namely, the adaptive success of (...) our species in a biological environment characterised by the survival of the fittest provides us with a reason to believe that our belief-forming mechanisms are truth-tracking; if they were not, we would have gone extinct. On the other hand, nevertheless, we find analyses—of which we will focus on the case of Ernest Sosa—according to which the tenet that our knowing capacities are reliable cannot be empirically based, and thus contingent; on the contrary, they point out that we need to presuppose—without need of a proof—that such capacities are trustworthy. Given this conflict between an “empirical” defence and a defence “in principle” of our knowing capacities, we will consider two possible objections against Sosa’s proposal and try to answer them.

How do agents with limited cognitive capacities flourish in informationally impoverished or unexpected circumstances? Aristotle argued that human flourishing emerged from knowing about the world and our place within it. If he is right, then the virtuous processes that produce knowledge, best explain flourishing. Influenced by Aristotle, virtue epistemology defends an analysis of knowledge where beliefs are evaluated for their truth and the intellectual virtue or competences relied on in their creation. However, human flourishing may emerge from how degrees of (...) ignorance are managed in an uncertain world. Perhaps decision-making in the shadow of knowledge best explains human wellbeing—a Bayesian approach? In this dissertation I argue that a hybrid of virtue and Bayesian epistemologies explains human flourishing—what I term homeostatic epistemology. Homeostatic epistemology supposes that an agent has a rational credence p when p is the product of reliable processes aligned with the norms of probability theory; whereas an agent knows that p when a rational credence p is the product of reliable processes such that: 1) p meets some relevant threshold for belief, 2) p coheres with a satisficing set of relevant beliefs and, 3) the relevant set of beliefs is coordinated appropriately to meet the integrated aims of the agent. Homeostatic epistemology recognizes that justificatory relationships between beliefs are constantly changing to combat uncertainties and to take advantage of predictable circumstances. Contrary to holism, justification is built up and broken down across limited sets like the anabolic and catabolic processes that maintain homeostasis in the cells, organs and systems of the body. It is the coordination of choristic sets of reliably produced beliefs that create the greatest flourishing given the limitations inherent in the situated agent. (shrink)

Practical wisdom (hereafter simply “wisdom”) is the intellectual virtue that enables a person to make reliably good decisions about how, all-things-considered, to live and conduct herself. Because wisdom is such an important and high-level achievement, we should wonder: what is the nature of wisdom? What kinds of skills, habits and capacities does it involve? Can real people actually develop it? If so, how? I argue that we can answer these questions by modeling wisdom on expert decision-making skill in complex areas (...) like firefighting. I develop this expert skill model of wisdom using philosophical argument informed by relevant empirical research. I begin in Chapter 1 by examining the historical roots of analogies between wisdom and practical skills in order to motivate the expert skill model. In Chapter 2, I provide the core argument for the expert skill model. I then use the remaining chapters to pull out the implications of the expert skill model. In Chapter 3, I show that the expert skill model yields practical guidance about how to develop wisdom. In Chapter 4, I address the objection, due to Daniel Jacobson, that wisdom is not a skill that humans could actually develop, since skill development requires a kind of feedback in practice that is not available for all-things-considered decisions about how to live. Finally, in Chapter 5, I apply the expert skill model to the question, much discussed by virtue ethicists, of whether a wise person deliberates using a comprehensive and systematic conception of the good life.

This research addresses the justificatory role of conscious reflection within a naturalized, reliabilist epistemology. Reliabilism is the view that implicit, mechanistic processes can justify beliefs, e.g. perceptual beliefs formed after a history of consistent exposure to normal lighting conditions are justified in a given context with normal lighting. A popular variant of reliabilism is virtue epistemology where the cognitive circumstances and abilities of an agent play a justificatory role, e.g. the cooperation of the prefrontal cortex and primary visual cortex of (...) the individual perceiving the Müller-Lyer illusion partly justify the belief that the lines are equi-length. While virtue epistemology is a well-endorsed reliabilism for implicit beliefs, its application to explicit, consciously reflective processes is more controversial. Critics ask: How can iterations of dumb reliabilist processes produce higher order justification? To respond to this concern, I draw on another agent-centred, normative and reliabilist epistemology—Bayesian epistemology. A Bayesian virtue epistemology argues that reflective hypothesis-testing generated by implicit Bayesian mechanisms offers higher order reliabilist justification for beliefs. Iterative Bayesian mechanisms explain the development of higher order beliefs about abstract concepts such as causation, natural laws and theoretical entities traditionally explained by recourse to vague concepts such as ‘the a priori’, ‘intuition’ or ‘the intellect’. A hybrid Bayesian virtue epistemology offers an iterative reliabilist framework to explain how conscious reflection justifies beliefs. However, I acknowledge limitations on Bayesian accounts of justification such as confirmational holism, commutativity, and the frame problem. (shrink)
