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.

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)

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)

Our true home is wilderness, even the world of everyday.—Henry G. Bugbee, Jr.Henry Bugbee was Born in New York City in 1915. This may not seem the most fortuitous birthplace for an interpreter of the wild rivers of Montana, but we might also remember that John Muir, interpreter of the High Sierras, was born in Scotland. Perhaps the movement west is an important prelude for such a vocation. Bugbee studied philosophy at Princeton and then at Berkeley, but before he could (...) finish his graduate work, he was called for naval service in the Pacific. The time at sea was a formative wilderness experience, on which his writing draws heavily. Returning from sea, he finished his PhD and took a teaching position at Harvard. Not .. (shrink)

Wilderness is often understood as land untouched by people. On this reading, wilderness management seems to be a simple contradiction, but it is in fact a thriving and functional practice. Wilderness is not simply an absence of human influence, but the presence of something else. Wilderness is land characterized by the flourishing of natural purpose. When this is understood, wilderness management becomes intelligible and several recent criticisms of wilderness preservation are defused.

We respond to the central concerns raised by our commentators to our book, The Epistemological Spectrum. Casullo believes that our account of what we term “low-grade a priori” justification provides important clarification of a kind of philosophical reflection. However he objects to calling such reflection a priori. We explain what we think is at stake. Along the way, we comment on his idea of that there may be an epistemic payoff to making a distinction between assumptions and presumptions. In the (...) book, we argued that an epistemically important form of nonaccidental reliability can be understood as a matter of processes being “transglobally reliable under modulational control.” Graham recommends another form of nonaccidental reliability, one rooted in evolutionary etiology. We explain why we think that the reliability of perceptual processes is best understood as turning of the kinds of modulational control that we highlight. We clarify how this approach represents a kind of reasonable epistemic patience—modulational control takes time, as it must turn on agents generating information about their own capacities and foibles. Lyons raises interesting questions regarding how (what we term) morphological content possessed by the agent can do the work that we set for it. We argue that it is necessary in order for agents to accommodate the background information that is relevant to many central problems of belief formation. We clarify how it can be expected to work.

David Henderson and Terry Horgan argue that doxastic epistemic justification requires the transglobal reliability of the belief-forming process. Transglobal reliability is reliability across a wide range of experientially possible global environments. Focusing on perception, I argue that justification does not require transglobal reliability, for perception is non-accidentally reliable and confers justification but not always transglobally reliable. Transglobal reliability is an epistemically desirable property of belief-forming processes, but not necessary for justification.

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)

The last decades have seen major advances in the study of gestures both in humans and non-human primates. In this paper, we seriously examine the idea that there may be gestural form types that are shared across great ape species, including humans, which may underlie gestural universals, both in form and meaning. We focus on one case study, the hand fling gesture common to chimpanzees and humans, and provide a semantic analysis of this gesture.

Teleosemantics seeks to explain meaning and other intentional phenomena in terms of their function in the life of the species. This volume of new essays from an impressive line-up of well-known contributors offers a valuable summary of the current state of the teleosemantics debate.

The advent of formal definitions of the simplicity of a theory has important implications for model selection. But what is the best way to define simplicity? Forster and Sober ([1994]) advocate the use of Akaike's Information Criterion (AIC), a non-Bayesian formalisation of the notion of simplicity. This forms an important part of their wider attack on Bayesianism in the philosophy of science. We defend a Bayesian alternative: the simplicity of a theory is to be characterised in terms of Wallace's Minimum (...) Message Length (MML). We show that AIC is inadequate for many statistical problems where MML performs well. Whereas MML is always defined, AIC can be undefined. Whereas MML is not known ever to be statistically inconsistent, AIC can be. Even when defined and consistent, AIC performs worse than MML on small sample sizes. MML is statistically invariant under 1-to-1 re-parametrisation, thus avoiding a common criticism of Bayesian approaches. We also show that MML provides answers to many of Forster's objections to Bayesianism. Hence an important part of the attack on Bayesianism fails. (shrink)

The proposal to create a chamber selected by sortition would extend this democratic procedure into the legislative branch of government. However, there are good reasons to believe that, as currently conceived by John Gastil and Erik Olin Wright, the proposal will fail to realize sufficiently two fundamental democratic goods, namely, political equality and deliberative reasoning. It is argued through analysis of its historic and contemporary application that sortition must be combined with other institutional devices, in particular, rotation of membership and (...) limited mandate, in order to be democratically effective and to realize political equality and deliberative reasoning. An alternative proposal for a responsive sortition legislature is presented as more realistic and utopian: one that increases substantially the number of members, makes more extensive use of internal sortition and rotation, and recognizes the importance of establishing limited mandates.

It is well known that Tarski proved a result which can be stated roughly as: no sufficiently rich, consistent, classical language can contain its own truth definition. Tarski's way around this problem is to deal with two languages at a time, an object language for which we are defining truth and a metalanguage in which the definition occurs. An obvious question then is: under what conditions can we construct a definition of truth for a given object language. Tarski claims that (...) it is necessary and sufficient that the metalanguage be "essentially richer". Our contention, put bluntly, is that this claim deserves more scrutiny from philosophers than it usually gets and in fact is false unless "essentially richer" means nothing else than "sufficient to contain a truth definition for the object language.".

Michael Friedman has recently argued that Carnap'sLogical Syntax of Language is fundamentally flawed in a way that reveals the ultimate failure of logical positivism. Friedman's argument depends crucially on two claims: (1) that Carnap was committed to the view that there is a universal metalanguage and (2) that given what Carnap wanted from a metalanguage, in particular given that he wanted a definition of analytic for an object language, he was in fact committed to a hierarchy of stronger and stronger (...) metalanguages. We argue that neither of these claims need be accepted. We show that there is no textual evidence for (1) and that if metalanguages are to be used for merely descriptive and not also justificatory purposes, Carnap does not need to define analyticity sufficiently for proving consistency, and so could have given a definition that does not entail a hierarchy of metalanguages.

Striking similarities across ape gestural repertoires suggest shared phylogenetic origins that likely provided a foundation for the emergence of language. We pilot a novel approach for exploring possible semantic universals across human and nonhuman ape species. In a forced‐choice task, n = 300 participants watched 10 chimpanzee gesture forms performed by a human and chose from responses that paralleled inferred meanings for chimpanzee gestures. Participants agreed on a single meaning for nine gesture forms; in six of these the agreed form‐meaning (...) pair response(s) matched those established for chimpanzees. Such shared understanding suggests apes' (including humans') gesturing shares deep evolutionary origins. (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)

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.

We criticise Shepard's notions of “invariance” and “universality,” and the incorporation of Shepard's work on inference into the general framework of his paper. We then criticise Tenenbaum and Griffiths' account of Shepard (1987b), including the attributed likelihood function, and the assumption of “weak sampling.” Finally, we endorse Barlow's suggestion that minimum message length (MML) theory has useful things to say about the Bayesian inference problems discussed by Shepard and Tenenbaum and Griffiths.

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.

Promyelocytic leukaemia nuclear bodies (PML NBs) are generally present in all mammalian cells, and their integrity correlates with normal differentiation of promyelocytes. Mice that lack PML NBs have impaired immune function, exhibit chromosome instability and are sensitive to carcinogens. Although their direct role in nuclear activity is unclear, PML NBs are implicated in the regulation of transcription, apoptosis, tumour suppression and the anti‐viral response. An emerging view is that they represent sites where multi‐subunit complexes form and where post‐translational modification of (...) regulatory factors, such as p53, occurs in response to cellular stress. Following DNA damage, several repair factors transit through PML NBs in a temporally regulated manner implicating these bodies in DNA repair. We propose that PML NBs are dynamic sensors of cellular stress, which rapidly disassemble following DNA damage into large supramolecular complexes, dispersing associated repair factors to sites of damage. The dramatically increased total surface area available would enhance interactions between PML‐associated factors regulating DNA repair and apoptosis.
