The application of machine learning algorithms to healthcare data can enhance patient care while also reducing healthcare worker cognitive load. These algorithms can be used to detect anomalous physiological readings, potentially leading to expedited emergency response or new knowledge about the development of a health condition. However, while there has been much research conducted in assessing the performance of anomaly detection algorithms on well-known public datasets, there is less conceptual comparison across unsupervised and supervised performance on physiological data. Moreover, while (...) heart rate data are both ubiquitous and noninvasive, there has been little research specifically for anomaly detection of this type of data. Considering that heart rate data are indicative of both potential health complications and an individual’s physical activity, this is a rich source of largely overlooked data. To this end, we employed and evaluated five machine learning algorithms, two of which are unsupervised and the remaining three supervised, in their ability to detect anomalies in heart rate data. These algorithms were then evaluated on real heart rate data. Findings supported the effectiveness of local outlier factor and random forests algorithms in the task of heart rate anomaly detection, as each model generalized well from their training on simulated heart rate data to real world heart rate data. Furthermore, results support that simulated data can help configure algorithms to a degree of performance when real labeled data are not available and that this type of learning might be especially helpful in initial deployment of a system without prior data.

Epistemic Evaluation aims to explore and apply a particular methodology in epistemology. The methodology is to consider the point or purpose of our epistemic evaluations, and to pursue epistemological theory in light of such matters. Call this purposeful epistemology. The idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. Several contributions to this volume explicitly address this general methodology, or some version of it. Others focus on (...) advancing some application of the methodology rather than on theorizing about it. The papers go on to explore the idea that purposes allow one to understand the conceptual demands on knowing, examine how purposeful epistemology might shed light on the debate between internalist and externalist epistemologies, and further develop the idea of purposeful epistemology.

The chapter rehearses the main outlines of gatekeeping contextualism—the view that it is central to the concept of knowledge that attributions of knowledge function in a kind of epistemic gatekeeping for contextually salient communities. The case for gatekeeping contextualism is clarified within an extended discussion of the character of philosophical reflection. The chapter argues that normatively valenced, evaluative concepts constitute a broad class of concepts for which a sociolinguistic point or purpose may be readily sensed—and for which the intimate connection (...) between point/purpose and the concept itself is readily understandable. Commonly at the inception of philosophical reflection one’s sense for the point or purpose of a specific concept is seldom highly articulate. The chapter argues that this does not prevent one’s grasp of point/purpose from doing real work in philosophical reflection. (shrink)

This introductory chapter proceeds in three parts. The first section characterizes the general approach to epistemology around which the volume revolves—purposeful epistemology—and examines the general motivation for that approach. The guiding idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. The second section explores the approach by characterizing some important versions of it. Several themes and issues that we see running through the volume are here articulated (...) and highlighted. The third section provides a brief summary of each contribution to the collection. (shrink)

After characterizing the general outlines of Davidson's criticism of the idea of conceptual schemes, the specifics of his argument are examined and evaluated. It is argued that his argument against radically different conceptual schemes does mark out plausible limits to what might be thought of as differences against conceptual schemes, but it is doubtful that those he mentioned as proponents of the idea envisions such differences. It is argued that the stylized character of Davidson's arguments against the less radical variants (...) of the idea fail to foreclose the possibility of differences that many would find interesting.

Rosenberg argues that intentional generalizations in the human sciences cannot be law-like because they are not amenable to significant empirical refinement. This irrefinability is said to result from the principle that supposedly controls in intentional explanation also serving as the standard for successful interpretation. The only credible evidence bearing on such a principle would then need conform to it. I argue that psychological generalizations are refinable and can be nomic. I show how empirical refinement of psychological generalizations is possible by (...) considering concrete cases. A sufficiently detailed view of the role of psychological generalizations in interpretation allows us to find in psychological investigations instances of bootstrap testing. (shrink)

One of the central points of contention in the epistemology of testimony concerns the uniqueness (or not) of the justification of beliefs formed through testimony--whether such justification can be accounted for in terms of, or 'reduced to,' other familiar sort of justification, e.g. without relying on any epistemic principles unique to testimony. One influential argument for the reductionist position, found in the work of Elizabeth Fricker, argues by appeal to the need for the hearer to monitor the testimony for credibility. (...) Fricker (1994) argues, first, that some monitoring for trustworthiness is required if the hearer is to avoid being gullible, and second, that reductionism but not anti-reductionism is compatible with ascribing an important role to the process of monitoring in the course of justifiably accepting observed testimony. In this paper we argue that such an argument fails. (shrink)

Henderson and Horgan set out a broad new approach to epistemology. They defend the roles of the a priori and conceptual analysis, but with an essential empirical dimension. 'Transglobal reliability' is the key to epistemic justification. The question of which cognitive processes are reliable depends on contingent facts about human capacities.

The concept of knowledge is used to certify epistemic agents as good sources (on a certain point or subject matter) for an understood audience. Attributions of knowledge and denials of knowledge are used in a kind of epistemic gate keeping for (epistemic or practical) communities with which the attributor and interlocutors are associated. When combined with reflection on kinds of practical and epistemic communities, and their situated epistemic needs for gate keeping, this simple observation regarding the point and purpose of (...) the concept of knowledge has rich implications. First, it gives one general reason to prefer contextualism over various forms of sensitive invariantism. Second, when gate keeping for a select community of experts or authorities, with an associated body of results on which folk generally might then draw (when gate keeping for a general source community ) the contextual demands approximate those with which insensitive invariantists would be comfortable.

People develop and deploy epistemic norms – normative sensibilities in light of which they regulate both their individual and community epistemic practice. There is a similarity to folk's epistemic normative sensibilities – and it is by virtue of this that folk commonly can rely on each other, and even work jointly to produce systems of true beliefs – a kind of epistemic common good. Agents not only regulate their belief forming practices in light of these sensitivities, but they make clear (...) to others that they approve or disapprove of practices as these accord with their sensibilities – they thus regulate the belief forming practices of others in an interdependent pursuit of a good – something on the order of a community stock of true beliefs. Such general observations suggest ways in which common epistemic norms function as social norms, as these are characterized by Cristina Bicchieri's (2006) discussion of various kinds of norms. I draw on this framework – together with an important elaboration in Bicchieri (2017) – as it affords an analysis of the various related ways in which normative sensibilities function in communities of interdependent agents. The framework allows one to probe how these normative sensibilities function in the various associated choice situations. I argue that epistemic norms are fundamentally social norms, and, at the same time, they also are widely shared sensibilities about state-of-the-art ways of pursuing projects of individual veritistic value. The two foundations suggest the analogy of an arch. (shrink)

This paper explores a position that combines contextualism regarding knowledge with the idea that the central point or purpose of the concept of knowledge is to feature in attributions that keep epistemic gate for contextually salient communities. After highlighting the main outlines and virtues of the suggested gate-keeping contextualism, two issues are pursued. First, the motivation for the view is clarified in a discussion of the relation between evaluative concepts and the purposes they serve. This clarifies why one's sense for (...) the point of an evaluative concept ought to constrain and inform one's understanding of the concept. Second, the paper explores ways of avoiding a problem in the author's earlier development of gate-keeping contextualism. The initial development of the view opened the door to a form of skepticism that would hobble an important facet of our social-epistemic lives. (shrink)

This paper is a beginning—an initial attempt to think of the function and character of epistemic norms as a kind of social norm. We draw on social scientific thinking about social norms and the social games to which they respond. Assume that people individually follow epistemic norms for the sake of acquiring a stock of true beliefs. When they live in groups and share information with each other, they will in turn produce a shared store of true beliefs, an epistemic (...) public good. True beliefs, produced individually or in groups, constitute an epistemic good—one commonly stockpiled and distributed within a community. Epistemic norms can then be understood as a kind of socially developed and transmitted normative sensibility having to do with the production of this individual and public good. Epistemic norms should serve to regulate this practice—coordinating the practice of individuals so as to afford the benefits of life in an interdependent epistemic community—and to manage the risks of being epistemically dependent on others within such a community. Here, we provide some attempts to characterize the central aspects of "the epistemic game"—the epistemic choice situation confronted by communities of epistemic agents. (shrink)

This chapter examines how epistemic norms could be social norms, with a reliance on work on the philosophy and social science of social norms from Bicchieri (on the one hand) and Brennan, Eriksson, Goodin and Southwood (on the other hand). We explain how the social ontology of social norms can help explain the rationality of epistemic cooperation, and how one might begin to model epistemic games.

Accounts of what it is for an agent to be justified in holding a belief commonly carry commitments concerning what cognitive processes can and should be like. A concern for the plausibility of such commitments leads to a multi-faceted epistemology in which elements of traditionally conflicting epistemologies are vindicated within a single epistemological account. The accessible and articulable states that have been the exclusive focus of much epistemology must constitute only a proper subset of epistemologically relevant processing. The interaction of (...) such states looks rather contextualist. It might also be called quasi-foundationalist. However, in attending to our epistemological tasks we must rely on processing that is sensitive to information that we could not articulate, that is not accessible in the standard internalist sense. When focusing on the full range of epistemologically important processes, the structure of what makes for justification is rather more like that envisioned by some coherentists. (shrink)

Alvin Goldman’s contributions to contemporary epistemology are impressive—few epistemologists have provided others so many occasions for reflecting on the fundamental character of their discipline and its concepts. His work has informed the way epistemological questions have changed (and remained consistent) over the last two decades. We (the authors of this paper) can perhaps best suggest our indebtedness by noting that there is probably no paper on epistemology that either of us individually or jointly have produced that does not in its (...) notes and references bear clear testimony to the influence of Professor Goldman’s arguments. The present paper is no exception (and this would be a particularly inapt place to break with our tradition of indebtedness). Professor Goldman has produced a series of discussions that we find particularly important for coming to terms with the venerable idea that there may be truths that can be known a priori (Goldman 1992a, 1992b, 1999). We do not altogether follow his lead, while he draws on the idea that a priori justification has something to do with innateness or processess, we prefer to accentuate the idea that a priori justification turns on a conceptually grounded truths and access via acquired conceptual competence (at least in many significant philosophical cases). Still, in developing our understanding we have been aided by much that Professor Goldman says regarding concepts, conceptual competence, and related psychological processes. The influences should become progressively clear, particularly in the later sections of this paper. What would it take for there to be a priori knowledge or justification? We can begin by reflecting on a widely agreed on answer to this question—one that purports to identify something that would at least be adequate for a priori justification. The answer will then serve as one anchor for the present investigation, a bit of shared ground on which empiricists and rationalists can, and typically do, agree.. (shrink)

In "Epistemic Norms and the 'Epistemic Game' They Regulate", we advance a general case for the idea that epistemic norms regulating the production of beliefs might usefully be understood as social norms. There, we drew on the influential account of social norms developed by Cristina Bicchieri, and we managed to give a crude recognizable picture of important elements of what are recognizable as central epistemic norms. Here, we consider much needed elaboration, suggesting models that help one think about epistemic communities (...) and, ultimately, the temptations confronted in one's epistemic life. We suggest that once "the epistemic game" is embedded into a wider set of gains and losses, one can understand the epistemic choice situation as a form of mixed-motive game. This allows one to understand epistemic games more straightforwardly using Bicchieri's framework for thinking about social norms. That is, once the choice situation denominated only in terms of classical epistemic gains and losses is embedded in a wider accounting of goods that may compete with the production of true beliefs, one can see how an agent's individual and community epistemic project can be furthered by social norms regulating epistemic practices. We recommend thinking of epistemic norms as analogous to social norms for hygiene. (shrink)

Common formulations of the principle of charity in translation seem to undermine attributions of irrationality in social scientific accounts that are otherwise unexceptionable. This I call the problem of irrationality. Here I resolve the problem of irrationality by developing two complementary views of the principle of charity. First, I develop the view (ill-developed in the literature at present) that the principle of charity is preparatory, being needed in the construction of provisional first-approximation translation manuals. These serve as the basis for (...) explanatory accounts and associated refinements in the translation manual. In developing such explanatory accounts, the principle of charity is no longer constraining. Thus, the principle of charity applies only in the early stages of constructing translation manuals, and there is no problem of irrationality in the later stages of constructing translation manuals. Second, I reduce the principle of charity, where it does apply, to a special case of what I call the principle of explicability: so translate as to attribute explicable beliefs and practices to the speakers of the source-language. I show that the appropriate formulation of the principle of charity counsels just what the principle of explicability requires in the early stages of social scientific investigation. (shrink)

Reliablists have argued that the important evaluative epistemic concept of being justified in holding a belief, at least to the extent that that concept is associated with knowledge, is best understood as concerned with the objective appropriateness of the processes by which a given belief is generated and sustained. In particular, they hold that a belief is justified only when it is fostered by processes that are reliable (at least minimally so) in the believer’s actual world.[1] Of course, reliablists typically (...) recognize other concepts of justification--typically subjective notions--which are given a noncompeting sort of epistemic legitimacy. However, they have tended to focus on the epistemically central notion of "strong justification," and have come to settle on this familiar reliablist analysis, supposing that it pretty much exhausts what there is to say about "objective justification.".

Michael Hannon advocates an epistemological methodology – tracing its roots, articulating refinements, distinguishing it from alternative methodologies and giving reasons for preferring it to the alternatives. He also advances an account of knowledge as a compelling application of this methodology. As reflected in his title, both projects are pivotal to the work and intimately related. In its general outlines, I judge that that case for the method should be taken to heart – although details could stand for further attention – (...) and that its application does advance our epistemological understanding.

We propose an approach to epistemic justification that incorporates elements of both reliabilism and evidentialism, while also transforming these elements in significant ways. After briefly describing and motivating the non-standard version of reliabilism that Henderson and Horgan call “transglobal” reliabilism, we harness some of Henderson and Horgan’s conceptual machinery to provide a non-reliabilist account of propositional justification (i.e., evidential support). We then invoke this account, together with the notion of a transglobally reliable belief-forming process, to give an account (...) of doxastic justification. (shrink)

This paper brings together two lines of thought. The first is the broadly contextualist idea that what is takes to satisfy central epistemic concepts such as the concept of knowledge or that of objectively justified belief may vary with the stakes faced in settings or contexts. Attributions of knowledge, for example, certify an agent to those who might treat them as a source on which to rely. Henderson and Horgan write of gate-keeping for an epistemic community. The second line (...) of thought turns on the idea that such central epistemic concepts are keyed to the conformity with epistemic norms for the fitting fixation of belief—and that the epistemic norms function in important ways as social norms by which folk regulate their epistemic lives as members of communities of interdependent agents. The two lines of thought are practically made for one another! I develop the connections and show how the results both vindicate and reinforce a form of contextualist epistemology, but refine and limit the range of contextual variation one should envision.

The authors argue in favor of the “nonconciliation” (or “steadfast”) position concerning the problem of peer disagreement. Throughout the paper they place heavy emphasis on matters of phenomenology—on how things seem epistemically with respect to the net import of one’s available evidence vis-à-vis the disputed claim p, and on how such phenomenology is affected by the awareness that an interlocutor whom one initially regards as an epistemic peer disagrees with oneself about p. Central to the argument is a nested goal/sub-goal (...) hierarchy that the authors claim is inherent to the structure of epistemically responsible belief-formation: pursuing true beliefs by pursuing beliefs that are objectively likely given one’s total available evidence; pursuing this sub-goal by pursuing beliefs that are likely true (given that evidence) relative to one’s own deep epistemic sensibility; and pursuing this sub-sub-goal by forming beliefs in accordance with one’s own all-in, ultima facie, epistemic seemings.

The doctrine is familiar. In a sentence, a priori truths are those that are knowable on the basis of reflection alone (independent of experience) by anyone who has acquired the relevant concepts. This expresses the classical conception of the a priori. Of course, there are those who despair of finding any truths that fully meet these demands. Some of the doubters are convinced, however, that the demands, are somewhat inflated by an epistemological tradition that was nevertheless on to something of (...) importance. These thinkers would then seek to reconceive the a priori somewhat--accommodating some of the classical demands within a "retentive analysis." Ultimately, we will urge a place for both the classical conception and a complementary revisionary but retentive conception as well. (shrink)

The papers in this issue all concern the normative standards by which we do or should regulate our joint epistemic lives in communities. Plausibly, reflection on how we should regulate ourselves—what one should insist on in one's own practice and that of one's epistemic partners—takes some cues from reflection on what we do insist on. The reverse is plausibly also the case. These papers also, more or less explicitly, suggest that our epistemic sensibilities themselves reflect the demands of epistemic practice (...) within a community of interdependent agents. (shrink)

Familiar accounts have it that one explains thoughts or actions by showing them to be rational. It is common to find that the standards of rationality presupposed in these accounts are drawn from what would be thought to be aprioristic sources. I advance an argument to show this must be mistaken. But, recent work in epistemology and on rationality takes a less aprioristic approach to such standards. Does the new (psychological or cognitive scientific) realism in accounts of rationality itself significantly (...) improve the prospects for unproblematic forms of rationalizing explanation? Do earlier misgivings about rationalizing explanation ring hollow when the rationality to be attributed is "naturalized"? Answer: while explanation in terms of naturalized rationality would be free of one fatal flaw possessed by explanation in terms of rationality understood in the traditional fashion, it would yet have parallel flaws.

It seems that hope springs eternal for the cherished idea that norms (or normativeprinciples) explain actions or regularities in actions. But it also seems thatthere are many ways of going wrong when taking norms and normative principlesas explanatory. The author argues that neither norms nor normative principles—insofar as they are the sort of things with normative force—is explanatoryof what is done. He considers the matter using both erotetic and ontic models ofexplanation. He further considers various understandings of norms. Key Words: (...) explanation • norms • social science • rationality.

A key philosophical feature of Peter Jackson’s film interpretation of J.R.R. Tolkien’s _The Lord of the Rings_ is its use of fantasy to inspire a “recovery” of the actual or, in other words, a reawakening to the beauty of nature and the many possible ways of living in healthier ecological relation to the world. Though none of these ways is perfectly achieved, this pluralistic view is demonstrated in the various lifeways of Hobbits, Elves, Men, and Ents. All of the positive (...) relationships embodied in the films—to trees, mountains, horses, and vegetable gardens—involve loving care and attention, receiving nourishment and livelihood without instrumentalization, or reducing nature to mere resource. The films also vividly display a variety of ugly and destructive ways of using the land to accrue power and wealth. These noxious ways, specifically because they actively destroy the lands that they use, always need more. They will thus eventually annihilate the beautiful ways of being if they are not actively resisted. Some of those who would rather be tending their own trees, gardens, or horses or even wandering in the wild forests must therefore turn their attention to struggle and resistance instead. This is a struggle full of grief, and at times even verging on despair, but it is marked by the refusal to give up hope. Indeed, what Jackson and Tolkien have to say about hope is as important in responding to the ecological crisis as anything they have to say about nature, inasmuch as they help to remind us that even in our own times, “there is still hope.”.

We here propose an account of what it is for an agent to be objectively justified in holding some belief. We present in outline this approach, which we call transglobal reliabilism, and we discuss how it is motivated by various thought experiments. While transglobal reliabilism is an externalist epistemology, we think that it accommodates traditional internalist concerns and objections in a uniquely natural and respectful way.

This paper explores the role and limits of cognitive simulation in understanding or explaining others. In simulation, one puts one's own cognitive processes to work on pretend input similar to that one supposes that the other plausibly had. Such a process is highly useful. However, it is also limited in important ways. Several limitations fall out from the various forms of cognitive diversity. Some of this diversity results from cultural differences, or from differences in individuals' cognitive biographies. Such diversity is (...) clearly important in history. Some sorts of such diversity are discussed, with attention to the results of contemporary cognitive science. It is argued that one must sometimes employ mixed (simulation-based/theory-based) strategies, and that sometimes what is done will be neither purely simulation nor purely theory-based. (shrink)

Epistemology has recently come to more and more take the articulate form of an investigation into how we do, and perhaps might better, manage the cognitive chores of producing, modifying, and generally maintaining belief-sets with a view to having a true and systematic understanding of the world. While this approach has continuities with earlier philosophy, it admittedly makes a departure from the tradition of epistemology as first philosophy.

This paper provides an alternative narrative for organizing food systems. It introduces meshwork as a novel theoretical lens to examine the ontological assumptions underlying the shadow and informal dynamics of organizing food. Through a longitudinal qualitative case study, we place relationality and becoming at the centre of organizing food and food systems, demonstrating how entangled relationships can create a complex ontology through the meshwork knots, threads and weave. We show how issues of collective concern come together to form dynamic knots (...) of interactions, how the threads within the meshwork indicate processes of movement, and how the weave suggests degrees of food system resilience—but always in flow. This theoretical approach thus provides a platform for addressing thoughtful concerns about “food matters” including the integrity of our global food system, the negative health and environmental impacts of industrialized food production, and food safety issues.
