We highlight connections between accessible categories and abstract elementary classes , and provide a dictionary for translating properties and results between the two contexts. We also illustrate a few applications of purely category-theoretic methods to the study of AECs, with model-theoretically novel results. In particular, the category-theoretic approach yields two surprising consequences: a structure theorem for categorical AECs, and a partial stability spectrum for weakly tame AECs.

We present a way of topologizing sets of Galois types over structures in abstract elementary classes with amalgamation. In the elementary case, the topologies thus produced refine the syntactic topologies familiar from first order logic. We exhibit a number of natural correspondences between the model-theoretic properties of classes and their constituent models and the topological properties of the associated spaces. Tameness of Galois types, in particular, emerges as a topological separation principle. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We introduce a family of rank functions and related notions of total transcendence for Galois types in abstract elementary classes. We focus, in particular, on abstract elementary classes satisfying the condition known as tameness, where the connections between stability and total transcendence are most evident. As a byproduct, we obtain a partial upward stability transfer result for tame abstract elementary classes stable in a cardinal $\lambda$ satisfying $\lambda^{\aleph_{0}}\gt \lambda$, a substantial generalization of a result of Baldwin, Kueker, and VanDieren.

We exhibit a bridge between the theory of cellular categories, used in algebraic topology and homological algebra, and the model-theoretic notion of stable independence. Roughly speaking, we show that the combinatorial cellular categories (those where, in a precise sense, the cellular morphisms are generated by a set) are exactly those that give rise to stable independence notions. We give two applications: on the one hand, we show that the abstract elementary classes of roots of Ext studied by Baldwin–Eklof–Trlifaj are stable (...) and tame. On the other hand, we give a simpler proof (in a special case) that combinatorial categories are closed under 2-limits, a theorem of Makkai and Rosický. (shrink)

We broaden the framework of metric abstract elementary classes (mAECs) in several essential ways, chiefly by allowing the metric to take values in a well-behaved quantale. As a proof of concept we show that the result of Boney and Zambrano (Around the set-theoretical consistency of d-tameness of metric abstract elementary classes, arXiv:1508.05529, 2015) on (metric) tameness under a large cardinal assumption holds in this more general context. We briefly consider a further generalization to partial metric spaces, and hint at connections (...) to classes of fuzzy structures, and structures on sheaves. (shrink)

We provide comprehensive, level-by-level characterizations of large cardinals, in the range from weakly compact to strongly compact, by closure properties of powerful images of accessible functors. In the process, we show that these properties are also equivalent to various forms of tameness for abstract elementary classes. This systematizes and extends results of [W. Boney and S. Unger, Large cardinal axioms from tameness in AECs, Proc. Amer. Math. Soc.145(10) (2017) 4517–4532; A. Brooke-Taylor and J. Rosický, Accessible images revisited, Proc.

In lieu of an abstract, here is a brief excerpt of the content:Recovering One's Self from PsychosisA Philosophical AnalysisThe author reports no conflicts of interest.Rosanna Wannberg (2024) has given us a dense but helpful introduction to certain philosophical questions raised by the fact that many patients recovering from psychotic illnesses describe their recovery in terms of gaining or regaining a 'sense of self' and a 'sense of agency,' which often involves acceptance of the 'fact' of being mentally ill, for example, (...) of 'having schizophrenia.' She raises two important questions: How should we understand what is going on in these accounts? and What are the implications of these reports for our understanding of what it is to have a 'sense of self' or a 'sense of agency'—of 'subjectivity' generally—which might have, both, clinical and nonclinical implications?What does it mean to have a self or a sense of having one, agency or a sense of having it? One might think these are the possession or experience of something 'inner' such as feelings of confidence or assurance, perhaps having a kind of inner structure or a set of deeply held ideas which give us coherence, motivate us and justify our actions, and which we can know by 'looking inward,' in an introspective act which provides direct, privileged acquaintance.Yet Wittgenstein called this a dangerously misleading 'picture' which 'held us captive,' and needed always to be 'gotten rid of' (Wittgenstein, 1958). One way of seeing the problem is to consider that no inner 'object,' no thing inside us, can be, or give us a sense of having, a self or agency, because no mere thing (whether an experience of confidence, or having an inner structure) can have any meaning or provide any explanation. A thing (like a word on a page) is just a thing—inert, dead— and must be interpreted, that is used, before it can play a role in our 'forms of life' (Wittgenstein, 1958) including explaining our sense of self or agency.Semantic externalists (Burge, 1979; Putnam, 1975), have argued that even what is internal to our minds—like thoughts—have contents which are determined by experiences in the 'outside' world in which we have lived and learned: if our experiences in the world, they have shown, were different, then so, also, would be the contents of our thoughts. It has even been argued that internal mental experiences which appear to be purely phenomenological (such as an image or a thought-token, so-called narrow content) can only [End Page 67] be identified and thought about using concepts having references in the external world: there is, so it is claimed, no narrow content (Yli-Vakkuri and Hawthorne, 2018); or, if there is, it is of no explanatory use in psychology (Fodor, 1994).If this is the philosophical background from which Wannberg confronts first-person accounts of recovery from psychosis which include (re)gaining a sense of self or agency, and if this philosophy is right, what becomes of the accounts? How are they to be understood?To meet this challenge, Wannberg invokes an alternative account of self-possession and firstperson authority provided by Richard Moran (2001). Moran's position is that we find or possess ourselves when we find or hold beliefs about the world which we do not merely believe but endorse or avow, where to endorse or avow a belief about the world is to find and endorse reasons in the world, which support that belief. Thus, I can avow that it's raining if I can look outside and see that it is raining. This Moran calls the transparency condition. Endorsing or avowing both a belief and the external reasons for it gives the self what Moran refers to as authenticity and which also might be said to provide cohesion, consistency and intelligibility—plausibly, a 'sense of self.'The transparency condition also applies to beliefs that justify actions. We act intentionally when we can give good reasons for what we do (Anscombe, 1957; Moran, 2001) and we can give good reasons for what we do when we can identify facts in the world that support those reasons. Thus, the transparency condition can explain both a sense of self and a sense... (shrink)

The renowned cognitive scientist Philip Lieberman demonstrates that there is no better guide to the world's living--and still evolving--things than Darwin and that the phenomena he observed are still being explored at the frontiers of science. Lieberman relates the insights that led to groundbreaking discoveries in both Darwin's time and our own.

In lieu of an abstract, here is a brief excerpt of the content:The Meanings and Function of Anti-System Ideology in the Weimar RepublicBen LiebermanThere are few, if any, ideological terms in the extensive historiography of the Weimar Republic so omnipresent and yet at the same time so obscure as the word “system.” Historical accounts of the Weimar Republic are strewn with references to the “system.” In recent works on the Weimar Republic Hagen Schulze points to the opposition of bourgeois (bürgerliche) (...) parties to the “Weimar ‘system,’ “ Detlev Peukert notes “hatred of ‘the system,’ the political and social order of the Republic”; Knut Borchardt observes the loss of faith in the capacity of “the system” to satisfy expectations; and Hans Mommsen refers to the “political system,” the “party system” and the “parliamentary system.” 1Historians, whatever their other differences, agree that mounting opposition to the System weakened the Weimar Republic, but the usefulness of this observation requires analysis of the meaning or meanings of the System. What, then, was the Weimar System? Surprisingly, many accounts of the Weimar Republic do not even attempt to provide a definition of the System, and the term receives only cursory treatment in several specialized works on ideology of the Weimar era. 2 Anti-System politics does receive attention, but Thomas [End Page 355] Childers’s insightful and pioneering essay on “anti-system politics” concentrates on mobilization against the System rather than on the problem of defining it. 3The best existing analysis of the System in Kurt Sontheimer’s valuable study of anti-democratic thought in the Weimar Republic suggests that historians cannot take the meaning of the term as a given. Sontheimer establishes that the System formed part of the array of anti-democratic thought of the Weimar Republic, but he also notes that the term’s meaning cannot easily be pinned down. The System conveyed a variety of political and economic meanings and ultimately formed a “nationalist counter myth.” 4During the Weimar Republic, attacks against the System emanated from a wide range of sources, most notably from a variety of nationalists as well as from Communists. Nationalists of many leanings detested the System. The DNVP (German National People’s Party), the largest political party of the right for most of the Weimar Republic, hated the System. So, too, did conservative revolutionaries and völkisch (ethnic or racist nationalist) groups including nationalist associations and the National Socialists. At the other end of the political spectrum, attacks against the System also surfaced in the pronouncements of the KPD (German Communist Party). 5No single ideological line of attack doomed the Weimar Republic, but use by an extraordinarily broad range of political groups lent tremendous force to anti-System discourse. Adopted by foes who sometimes agreed on little else, the System was the targets of repeated attacks spread across the German political spectrum and called into question Weimar legitimacy. Analyzing this broad pattern of use raises several tasks. As a prelude to investigating anti-System terminology, it is necessary to map out the patterns of use of the System during the Weimar Republic. The very ability of rival groups to adopt anti-System suggests that the System incorporated varied meanings.Beyond investigating the meaning or meanings of the System, an analysis of anti-System terminology should also explore the appeal and influence of anti-System terminology. Why did such a broad range of groups adopt anti-System discourse, and how did acceptance of anti-System terminology help to discredit the Weimar Republic and designate alternatives for Germany’s future? [End Page 356]Describing Weimar’s perceived failings, anti-System terminology simultaneously provided a partial guide to a presumably-better Germany without the System. The System came to envelop many institutions of German public life, but attention should also be paid to spaces left unoccupied by the System. What, if any, institutions or structures of public life were left untainted by the broad wave of attacks against the System? If the hated System could be swept away, what would be left in its place? It is noteworthy that the many enemies of the System generally desired a strong state.Exploring the effects of broad attacks against the System, analysis of the System should also... (shrink)

Inferences made from endocasts of fossil skulls cannot provide information on the function of particular neocortical areas or the subcortical pathways to prefrontal cortex that form part of the neural substrate for speech, syntax, and certain aspects of cognition. The neural bases of syntax cannot be disassociated from “communication.” Manual motor control was probably a preadaptive factor in the evolution of humansyntactic ability, but neurophysiological data on living humans show that speech motor control and syntax are more closely linked. The (...) evolution of fully modern speech occurred fairly recently; thoughHomo habilismay have had some degree of speech and syntactic ability, it was not fully modern.

We show that metric abstract elementary classes are, in the sense of [15], coherent accessible categories with directed colimits, with concrete ℵ1-directed colimits and concrete monomorphisms. More broadly, we define a notion of κ-concrete AEC—an AEC-like category in which only the κ-directed colimits need be concrete—and develop the theory of such categories, beginning with a category-theoretic analogue of Shelah’s Presentation Theorem and a proof of the existence of an Ehrenfeucht–Mostowski functor in case the category is large. For mAECs in particular, (...) arguments refining those in [15] yield a proof that any categorical mAEC is μ-d-stable in many cardinals below the categoricity cardinal. (shrink)

This book defends a form of ethical intuitionism, according to which (i) there are objective moral truths; (ii) we know some of these truths through a kind of immediate, intellectual awareness, or "intuition"; and (iii) our knowledge of moral truths gives us reasons for action independent of our desires. The author rebuts all the major objections to this theory and shows that the alternative theories about the nature of ethics all face grave difficulties.

In lieu of an abstract, here is a brief excerpt of the content:The Nature of Proof in PsychiatryPaul Lieberman (bio)Keywordspsychotherapy process, knowledge and psychiatry, externalism, WittgensteinThis vivid clinical report illustrates recognizably, and provocatively, a number of routine, but often unexamined, clinical questions. In its few paragraphs, it depicts challenges that each practitioner confronts, and, in the flux of clinical work, addresses, however implicitly and imperfectly, every day: From what data, and by what processes, does a clinical formulation, or way (...) of understanding, come into being? How do we appraise its accuracy and adequacy? Of what value is even a well-substantiated understanding, in the mind of the therapist, to the patient? What is the power of empathy as a treatment tool? How do we assess someone's status as a “good candidate for therapy?” When, typically, only the outlines of a problem are visible, and its origins and implications are largely hidden, by what right do we recommend psychotherapy, and with what conception, at what level of detail, of what its outcome will be? These are among the questions that Dr. Bailey's story challenges us to address.They are clinical questions, of course, because they deal with empirical matters of fact—psychological processes, outcomes studies, and evidence. But they are also philosophical because, as Freud insisted and Dr. Bailey shows, information obtained in the clinical situation often has power and authority that lead us to believe we understand what is going on, understand the other person, even in the absence of scientifically tested hypotheses, or the clear application of research-based evidence. Interactions between people—including clinical interactions—have a life and ability to engage us. Their meanings can seem so transparent and convincing that no doubt or questioning may seem cogent. At their most powerful, such experiences can reawaken us to important realms of experience and feeling which we might, otherwise, forget, ignore, suppress, deny, or in other ways keep out of awareness; they have the potential to arouse us and reconnect us with truths that, once revived, can seem both valid and important—perhaps the kind of experience that we may derive from works of art or literature (in fact, Dr. Bailey's account could be seen as a clinical parable—meant to be neither true nor false, but instructive). But even less dramatic examples are commonplace: we do routinely claim to know and be able to interpret and understand the actions of other people from our everyday interactions with and observations of them.What is less clear is how to account for these convictions and how to appraise their value, because they do not derive from established scientific procedures. Clinical intuition has a role throughout medicine, but we usually expect it to be subjected later to more rigorous tests to establish the correct diagnosis. Yet, as Dr. Bailey's case illustrates, clinical intuition in the psychiatric encounter seems somehow different. When Colin [End Page 225] leads Dr. Bailey to the conclusion that a “painful lack of wounds” has made him depressed, we find this credible. It seems similarly credible that Dr. Bailey might be anxious about his own capacity to defend his young family, because he says he is, that he perceives Colin as testing his manhood or sincerity, because that seems to fit Colin's temperament, that being accurately understood is helpful, because most of us have had that experience and valued it, and that, most generally, an absence of challenge or of activity could be depressing. But suppose a patient believed that a painful lack of wounds produced diabetes instead of depression, or suppose he had developed epilepsy and attributed that to an absence of combat experience. We might see these as ‘pre-scientific’ or ‘hypothesis-generating’ (or worse). By contrast, it seems timid to consider psychiatric formulations to be always and only provisional or hypothetical.In what ways and to what extent should we expect psychiatry to be different, and why? Several considerations suggest that psychiatry's reasons are not, always and everywhere, the same as those of general medicine, nor are its objectives.In general medicine, we distinguish between signs and symptoms, on the one hand, and “underlying” disease processes, on the other. But in psychiatry, this distinction can be... (shrink)

Putting feelings into words, or “affect labeling,” can attenuate our emotional experiences. However, unlike explicit emotion regulation techniques, affect labeling may not even feel like a regulatory process as it occurs. Nevertheless, research investigating affect labeling has found it produces a pattern of effects like those seen during explicit emotion regulation, suggesting affect labeling is a form of implicit emotion regulation. In this review, we will outline research on affect labeling, comparing it to reappraisal, a form of explicit emotion regulation, (...) along four major domains of effects—experiential, autonomic, neural, and behavioral—that establish it as a form of implicit emotion regulation. This review will then speculate on possible mechanisms driving affect labeling effects and other remaining unanswered questions. (shrink)

Virtually all philosophers agree that for a belief to be epistemically justified, it must satisfy certain conditions. Perhaps it must be supported by evidence. Or perhaps it must be reliably formed. Or perhaps there are some other "good-making" features it must have. But does a belief's justification also require some sort of awareness of its good-making features? The answer to this question has been hotly contested in contemporary epistemology, creating a deep divide among its practitioners. Internalists, who tend to focus (...) on scientific or theoretical beliefs as the ideal, insist that such awareness is required for justification. Externalists, who think children's ordinary beliefs in obvious facts are paradigm cases of justified belief, say it isn't required. Michael Bergmann's book offers a decisive refutation of internalism and a sustained defense of externalism. (shrink)

Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between situations where an individual him/herself is participating in inbreeding and inbreeding among other close relatives. The difference is merely quantitative, as fitness can be compromised via both routes. The question is whether humans are sensitive to the direct as well as indirect costs of inbreeding. Using (...) responses from a large population-based sample (27,364 responses from 2,353 participants), we found that human motivations to avoid inbreeding closely track the theoretical costs of inbreeding as predicted by inclusive-fitness theory. Participants were asked to select in a forced choice paradigm, which of two acts of inbreeding with actual family members they would want to avoid most. We found that the estimated fitness costs explained 83.6% of participant choices. Importantly, fitness costs explained choices also when the self was not involved. We conclude that humans intuit the indirect fitness costs of mating decisions made by close family members and that psychological inbreeding avoidance mechanisms extend beyond self-regulation.

Externalist theories of justification create the possibility of cases in which everything appears to one relevantly similar with respect to two propositions, yet one proposition is justified while the other is not. Internalists find this difficult to accept, because it seems irrational in such a case to affirm one proposition and not the other. The underlying internalist intuition supports a specific internalist theory, Phenomenal Conservatism, on which epistemic justification is conferred by appearances.

Across languages, children map words to meaning with great efficiency, despite a seemingly unconstrained space of potential mappings. The literature on how children do this is primarily limited to spoken language. This leaves a gap in our understanding of sign language acquisition, because several of the hypothesized mechanisms that children use are visual (e.g., visual attention to the referent), and sign languages are perceived in the visual modality. Here, we used the Human Simulation Paradigm in American Sign Language (ASL) to (...) determine potential cues to word learning. Sign‐naïve adult participants viewed video clips of parent–child interactions in ASL, and at a designated point, had to guess what ASL sign the parent produced. Across two studies, we demonstrate that referential clarity in ASL interactions is characterized by access to information about word class and referent presence (for verbs), similarly to spoken language. Unlike spoken language, iconicity is a cue to word meaning in ASL, although this is not always a fruitful cue. We also present evidence that verbs are highlighted well in the input, relative to spoken English. The results shed light on both similarities and differences in the information that learners may have access to in acquiring signed versus spoken languages. (shrink)

At the University of Sheffield during 2011 and 2012, a leading group of philosophers, psychologists, and others gathered to explore the nature and significance of implicit bias. The two volumes of Implicit Bias and Philosophy emerge from these workshops. Each volume philosophically examines core areas of psychological research on implicit bias as well as the ramifications of implicit bias for core areas of philosophy. Volume I: Metaphysics and Epistemology is comprised of two parts: “The Nature of Implicit Attitudes, Implicit Bias, (...) and Stereotype Threat,” and “Skepticism, Social Knowledge, and Rationality.” The first part contains chapters examining the relationship between implicit attitudes and “dual process” models of the mind; the role of affect in the formation and change of implicit associations; the unity (or disunity) of implicit attitudes; whether implicit biases are mental states at all; and whether performances on stereotype-relevant tasks are automatic and unconscious or intentional and strategic. The second part contains chapters examining implicit bias and skepticism; the effects of implicit bias on scientific research; the accessibility of social stereotypes in epistemic environments; the effects of implicit bias on the self-perception of members of stigmatized social groups as rational agents; the role of gender stereotypes in philosophy; and the role of heuristics in biased reasoning.

Causation: A Realist Approach Traditional empiricist accounts of causation and laws of nature have been reductionist in the sense of entailing that given a complete specification of the non-causal properties of and relations among particulars, it is therefore logically determined both what laws there are and what events are causally related. It is argued here, however, that reductionist accounts of causation and of laws of nature are exposed to decisive objections, and thus that the time has come for empiricists to (...) break with that tradition. -/- The basic goal of this book, therefore, is to set out and defend realistic accounts of those concepts. In the case of causal relations, for example, Tooley maintains that causation is basically a matter of theoretical relations between states of affairs that underlie and explain relative frequencies. He also argues that such an approach avoids the objections that tell against reductionist accounts and that it does so without making causal relations epistemologically inaccessible. (shrink)

Dignity plays a central role in current thinking about law and human rights, but there is sharp disagreement about its meaning. Combining conceptual precision with a broad historical background, Michael Rosen puts these controversies in context and offers a novel, constructive proposal. “Penetrating and sprightly...Rosen rightly emphasizes the centrality of Catholicism in the modern history of human dignity.

Whether or not one agrees with Rosen's arguments, there can be no doubt he has widened our horizons.” —Rae Langton, Times Literary Supplement. (shrink)

In this paper, I propose a new way of defining sport that I call a ‘core-periphery’ model. According to a core-periphery model, sport comes in degrees – what I refer to as ‘sport-likeness’ – and the aim of the philosopher of sport is to chart those dimensions along which an activity can be more or less a sport. By introducing the concept of sport-likeness, the core-periphery model complicates the picture of what is or is not a sport and encourages philosophers (...) interested in defining sport to engage with the social sciences in exploring the extension of the term sport in common usage. In this paper I present the results of a small survey about attitudes to sport, and use it to illustrate how a core-periphery definition of sport would proceed. (shrink)

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

In previous work I have argued against internalism by means of a dilemma intended to force all internalists to accept one of two undesirable options: either their internalism is unmotivated or it is saddled with vicious regress problems. Recently it has been argued that Phenomenal Conservatism—a theory of justification according to which justification depends on seemings—is a kind of internalism that can escape this dilemma. In this paper, I argue that Phenomenal Conservatism cannot escape my dilemma for internalism. In order (...) to do this, it is helpful to get clear on what Phenomenal Conservatism is saying, and for that reason I begin, in section I, by examining in some detail what seemings are. I then argue, in the remainder of the paper, that, whichever horn of the dilemma for internalism they take, Phenomenal Conservatives are in trouble. (shrink)

Can an ugly experiment be a good experiment? Philosophers have identified many beautiful experiments and explored ways in which their beauty might be connected to their epistemic value. In contrast, the present chapter seeks out (and celebrates) ugly experiments. Among the ugliest are those being designed by AI algorithms. Interestingly, in the contexts where such experiments tend to be deployed, low aesthetic value correlates with high epistemic value. In other words, ugly experiments can be good. Given this, we should conclude (...) that beauty is not generally necessary or sufficient for epistemic value, and increasing beauty will not generally tend to increase epistemic value. (shrink)

Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition of the 18th century Scottish (...) philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.
