If we agree with the notion of a global community, then we must extend our concepts of justice, fairness, and equity beyond national borders by supporting measures to decrease global warming and to increase foreign aid, argues Peter Singer.

We compare astronomers' removal of Pluto from the listing of planets and psychiatrists' removal of homosexuality from the listing of mental disorders. Although the political maneuverings that emerged in both controversies are less than scientifically ideal, we argue that competition for "scientific authority" among competing groups is a normal part of scientific progress. In both cases, a complicated relationship between abstract constructs and evidence made the classification problem thorny.

While in the beginning of the environmental debate, conflicts over environmental and technological issues had primarily been understood in terms of ‘‘risk’’, over the past two decades the relevance of ignorance, or nonknowledge, was emphasized. Referring to this shift of attention to nonknowledge the article presents two main findings: first, that in debates on what is not known and how to appraise it different and partly conflicting epistemic cultures of nonknowledge can be discerned and, second, that drawing attention to nonknowledge (...) in technology conflicts results in significant institutional effects and new constellations of actors in public debates. To illustrate and substantiate this political dynamics of nonknowledge we draw upon examples from the areas of agri-biotechnology and mobile phoning. In a first step, we develop in greater detail the concept of scientific cultures of nonknowledge and identify three such cultures involved in the social conflicts within the two areas. Subsequently, we analyze the specific dynamics of the politicisation of nonknowledge looking at the variety of actors involved and the pluralisation of perceptions and evaluations of what is not known. Then, we point out some of the institutional reactions to the political and cultural dynamics of scientific nonknowledge. We argue that the equal recognition of the diverse cultures of nonknowledge is a key prerequisite for socially legitimate and ‘‘robust’’ decision-making under conditions of politicised scientific nonknowledge.

In this remarkably clear and original study of the Tractatus Peter Carruthers has two principal aims. He seeks to make sense of Wittgenstein's metaphysical doctrines, showing how powerful arguments may be deployed in their support. He also aims to locate the crux of the conflict between Wittgenstein's early and late philosophies. This is shown to arise from his earlier commitment to the objectivity of logic and logical relations, which is the true target of attack of his later discussion of (...) rule-following. Within this general framework Dr Carruthers explores a number of themes, including the early Wittgenstein's doctrine of the priority of logic over metaphysics, the nature and purpose of his programme of analysis for ordinary language and the various possible arguments supporting the existence of Simples. He offers many original interpretations and defends them with considerable attention to textual detail, yet the book's clarity and directness will make it accessible to anyone acquainted with the Tractatus. It will be required reading for all serious students of Wittgenstein's philosophy. (shrink)

Libertarianism holds that agents initially fully own themselves and have moral powers to acquire property rights in external things under certain conditions. It is normally advocated as a theory of justice in the sense of the duties that we owe each other. So understood, it is silent about any impersonal duties (i.e., duties owed to no one) that we may have.

David Chalmers argues that virtual objects exist in the form of data structures that have causal powers. I argue that there is a large class of virtual objects that are social objects and that do not depend upon data structures for their existence. I also argue that data structures are themselves fundamentally social objects. Thus, virtual objects are fundamentally social objects.

"Modern History" versions of the etiological theory claim that in order for a trait X to have the proper function F, individuals with X must have been recently favored by natural selection for doing F (Godfrey-Smith 1994; Griffiths 1992, 1993). For many traits with prototypical proper functions, however, such recent selection may not have occurred: traits may have been maintained due to lack of variation or due to selection for other effects. I examine this flaw in Modern History accounts and (...) offer an alternative etiological theory, the Continuing Usefulness account, which appears to avoid such problems. (shrink)

Propositional quantifiers are added to a propositional modal language with two modal operators. The resulting language is interpreted over so-called products of Kripke frames whose accessibility relations are equivalence relations, letting propositional quantifiers range over the powerset of the set of worlds of the frame. It is first shown that full second-order logic can be recursively embedded in the resulting logic, which entails that the two logics are recursively isomorphic. The embedding is then extended to all sublogics containing the logic (...) of so-called fusions of frames with equivalence relations. This generalizes a result due to Antonelli and Thomason, who construct such an embedding for the logic of such fusions. (shrink)

Scientist, mathematician, thinker, the father of pragmatism, the inspiration for William James and John Dewey, Charles Peirce has remained until recently a philosopher's philosopher. Peirce trod a fine line between the extremes of nominalism and realism, tough-minded pragmatism and metaphysical speculation. As Peter Skagestad makes clear, Peirce's system of thought was fragmented, incomplete, and sometimes inconsistent. But one overriding concern gives unity to the whole: the road of inquiry must never be blocked.

RÉSUMÉLes œuvres musicales sont à la fois multiples et audibles. Dans le domaine de l'ontologie musicale, deux des principaux modèles conçus pour expliquer ces caractéristiques des œuvres musicales sont le modèle type/instanciation et le modèle étape/continuité. Julian Dodd a soutenu que le modèle type/instanciation a un avantage sur le modèle étape/continuité, car il peut offrir une explication directe de l'audibilité des œuvres musicales en termes de catégorie ontologique. Je défends le modèle étape/continuité contre l'argument de Dodd en invoquant une relation (...) de continuité qui unifie l’œuvre. (shrink)

Many calls have been made for more research on social studies teachers’ practices and preservice training. Instructional practices employed by teachers are important for encouraging student learning. However, there is a history of social studies teachers focusing much of their time on teacher-centered instructional techniques that have not demonstrated strong learning for students. Therefore it is important to examine not just how teachers chose to teach, but also where they may have learned to teach. This study examined data from the (...) Teaching and Learning International Survey (TALIS) 2018 of 240 secondary social studies teachers to understand what instructional practices they report employing and their feelings about their preparation. Data analysis provided direct empirical evidence of the power of teacher preparation programs to shape social studies teachers’ instructional practices well into their teaching careers. (shrink)

This paper brings together two theories that I have propounded separately elsewhere. The first is the view that concrete individuals are constituted completely by tropes, that they are trope bundles. The second and more recently developed theory is that of the two major categories of concrete individuals, continuants and occurrents, the latter are ontologically more basic than the former and that continuants are to be viewed as invariants among occurrents under equivalence relations. The latter theory embodies on its own an (...) account of the nature of identity through time of things that are in time but not extended in time. The question is whether this view is compatible with the trope bundle account of concrete particulars, and, assuming it is (both theories being separately attractive) whether bringing them together entails any modifications (other than complexity) to either theory. After examining likely metaphysical difficulties the tentative conclusion is that the attractiveness of the trope bundle theory persists despite the marriage, but that the mental picture of what tropes and trope bundles are must be overhauled.

Discovering a deep unity in Nietzsche's work by exploring the structure and argumentative movement of a wide range of his books, Berkowitz shows that Nietzsche is a moral and political philosopher in the Socratic sense whose governing question is, "What is the best life?".

We present Birch and colleagues with a dilemma. On one interpretation, they aim to chart the distribution of a sort of minimal perceptual awareness across the animal kingdom, where that awareness can be fully characterized in third-person psychological terms. On this interpretation, the project is worthy but dull, since it doesn’t touch the question that has excited most people: whether other animals are phenomenally conscious. On an alternative interpretation, in contrast, they hope to resolve this latter question, arguing that phenomenal (...) consciousness is extremely widespread. But if this is their intention, then their argument begs the question. (shrink)

Emotion Review, Volume 14, Issue 1, Page 3-14, January 2022. Advocates for the psychological construction of emotion view themselves as articulating a non-essentialist alternative to basic emotion theory's essentialist notion of affect programs. Psychological constructionists have also argued that holding essentialist assumptions about emotions engenders misconceptions about the psychological constructionist viewpoint. If so, it is important to understand what psychological constructionists mean by “essentialism” and “non-essentialism.” To advance the debate, I take a deeper dive into non-essentialism, comparing the non-essentialist views (...) of the early empiricists with those of the psychological constructionists, focusing on the theories of James Russell and Lisa Barrett. Using Lakatos’ notion of scientific research programs, I also describe how Russell's and Barrett's views have evolved into different and potentially competing research programs under the psychological constructionist banner.

In this comparative analysis of twelve focus groups conducted in Austria, France, and the Netherlands, we investigate how lay people come to terms with two biomedical technologies. Using the term ‘‘technopolitical culture,’’ we aim to show that the ways in which technosciences are interwoven with a specific society frame how citizens build their individual and collective positions toward them. We investigate how the focus group participants conceptualized organ transplantation and genetic testing, their perceptions of individual agency in relation to the (...) two technologies and to more collective forms of acting and governing, and also their understanding of the two technologies’ relationship to broader societal value systems. Against the background of the sustained political effort to build common European values, we suggest that more fine-grained attention toward the culturally embedded differences in coming to terms with biomedical technologies is needed.

Human Quality Treatment (HQT) is a theoretical approach expressing different ways of dealing with employees within an organization and is embedded in humanistic management tenants of dignity, care, and personal development, seeking to produce morally excellent employees. We build on the theoretical exposition and present a measure of HQT-Scale across several studies including cross-culturally to enhance confidence in our results. Our first study generates the 25 items for the HQT-Scale and provides initial support for the items. We then followed up (...) with a large study of managers (n = 363) from Nigeria in study 2, which confirms the theoretical properties of the five dimensions of HQT and highlights a two-factor construct: HQT Ethically Unacceptable and HQT Ethically Acceptable using a 20-item HQT-Scale. Study 3 with a large sample of New Zealand employees (n = 452) again confirms the nature of the construct and provides construct validity tests. Finally, using time-lagged data, study 4 (n = 308) focuses on New Zealand employees and job attitudes and behaviors, and a well-being outcome. That study not only confirms the theoretically implied effects but also shows the HQT Ethically Acceptable factor mediates the detrimental effects of HQT Ethically Unacceptable. Overall, our four studies provide strong support for the HQT-Scale and highlight important understandings of HQT and humanistic management in the workplace. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.2 (2003) 161-167 [Access article in PDF] Social, Cognitive, and Neural Constraints on Subjectivity and Agency:Implications for Dissociative Identity Disorder Peter Q. Deeley In this commentary, I consider Matthew's argument after making some general observations about dissociative identity disorder (DID). In contrast to Matthew's statement that "cases of DID, although not science fiction, are extraordinary" (p. 148), I believe that there are natural analogs (...) of the disorder that, when considered, make it seem less puzzling and exotic. After discussing these examples, I examine the relations between social, cognitive, and neural processes supporting subjectivity and agency, to identify sources of personal identity in cases of DID that can be used as a basis for assessing Matthew's points against Behnke and Sinnott-Armstrong. I am not proposing a comprehensive theory, but rather identifying what I believe are components of such a theory. I then outline an approach to determining criminal responsibility in DID, drawing on analogies with other psychiatric disorders. Dissociative Identity Disorder DID is a disorder described in DSM-IV, which "is characterised by the presence of two or more distinct identities or personality states that recurrently take control of the individual's behaviour accompanied by an inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness" (American Psychiatric Association, p. 519). Recognizing Personal Identity How is personal identity recognized in normal cognition? If we take personhood to involve recognition of continuity of social, psychological, and physical identity for a given individual, then such judgments are routinely made rapidly and automatically as an aspect of what has come to be termed social cognition (Adolphs 2003). There is likely to be considerable redundancy in [End Page 161] the types of information used to make judgments about whether a person is the same as one who was previously encountered, or perhaps heard about—for example, facial features, movement patterns, speech prosody, dress, speech content, gender, ethnicity, social role, among other features, all provide information about individual identity, and hence personhood. When uncertainty exists, it is likely to reflect a loss or alteration of cues that would ordinarily be used in a rapid, automatic, unexamined way (Adolphs 2003). In such extreme cases (for example, severe mental illness or disfigurement), the problem of identification becomes the subject of explicit reasoning (and hence of potential disagreement, because we then engage in post hoc rationalizations to establish criteria for determining personhood, whereas normally we rely on essentially automatic, implicit abilities that work in most circumstances, some of which make little use of linguistic representations and formal reasoning—for example, individual facial identity recognition, which may occur as quickly as 170 ms after stimulus onset [Adolphs 2003]). Nevertheless, examining our judgments and intuitions in cases that force us to explicitly consider whether personal identity is preserved may provide analogies and clues for how we should proceed with DID. Let us consider, then, some natural analogs of DID. Natural Analogs of DID Method Acting I suggest that method acting is an analog of DID (Manderino 1985). Method acting refers to an approach to acting training and performance in which emphasis is placed on intensely imagining and identifying with the mental life of the character being portrayed. Training courses and manuals list many techniques and practices that can be used to facilitate absorption in a role, drawing on different kinds of memory—for example, experiential memories, memories of others, general knowledge (semantic memory), and memories of sensations and feelings, to creative a vivid sense of the subjective experience and actions of the character. Manderino, a method acting teacher, comments: "it is important to investigate the way in which your own mental makeup can improperly influence a character. Insecurities, self-consciousness, shyness or self-doubts can maintain a strong hold, and permitting any of these feelings to enter a performance is to remain the actor and not enter into the mental life of the character. For some, acting allows personal problems to be left behind, and they are thankful for the complete escape that... (shrink)

Suppose that a sign at the entrance of a hotel reads: “Don’t enter these premises unless you are accompanied by a registered guest”. You see someone who is about to enter, and you tell her: “Don’t enter these premises if you are an unaccompanied registered guest”. She asks why, and you reply: “It follows from what the sign says”. It seems that you made a valid inference from an imperative premise to an imperative conclusion. But it also seems that imperatives (...) cannot be true or false, so what does it mean to say that your inference is valid? It cannot mean that the truth of its premise guarantees the truth of its conclusion. One is thus faced with what is known as “Jørgensen’s dilemma” (Ross 1941: 55-6): it seems that imperative logic cannot exist because logic deals only with entities that, unlike imperatives, can be true or false, but it also seems that imperative logic must exist. It must exist not only because inferences with imperatives can be valid, but also because imperatives (like “Enter” and “Don’t enter”) can be inconsistent with each other, and also because one can apply logical operations to imperatives: “Don’t enter” is the negation of “Enter”, and “Sing or dance” is the disjunction of “Sing” and “Dance”. A standard reaction to this dilemma consists in basing imperative logic on analogues of truth and falsity. For example, the imperative “Don’t enter” is satisfied if you don’t enter and is violated if you enter, and one might say that an inference from an imperative premise to an imperative conclusion is valid exactly if the satisfaction (rather than the truth) of the premise guarantees the satisfaction of the conclusion. But before getting into the details, more needs to be said on what exactly imperatives are. (shrink)

BackgroundPatient-centred care and patient autonomy is one of the key factors to better quality of service provision, hence patient outcomes. It enables the development of patients’ trusts which is an important element to a better doctor-patient relationship. Given the increasing number of patient disputes and conflicts between patients and doctors in Chinese public hospital, it is timely to ensure patient-centred care is fully and successfully implemented. However, limited studies have examined the views and practice in different aspects of patient-centred care (...) among doctors in the Chinese public hospitals.MethodsA quantitative approach was adopted by distributing paper-based questionnaires to doctors and patients in two hospitals (Level III and Level II) in Jinan, Shandong province, China.ResultsIn total, 614 doctors from the surgical and internal medicine units of the two hospitals participated in the survey yielding 90% response rates. The study confirmed the inconsistent views among doctors in terms of their perception and practice in various aspects patient-centred care and patient autonomy regardless of the hospital where they work (category II or category III), their unit speciality (surgical or non-surgical), their gender or seniority. The high proportion of doctors (more than 20%) who did not perceive the importance of patient consultation prior to determining diagnostic and treatment procedure is alarming. This in in part due to the belief held by more than half of the doctors that patients were unable to make rational decisions and their involvement in treatment planning process did not necessarily lead to better treatment outcomes.ConclusionThe study calls for the development of system level policy and organisation wide strategies in encouraging and enabling the practice of patient-centred care and patient autonomy with the purposes of improving the quality of the service provided to patients by Chinese hospitals.

In the first two volumes of On What Matters Derek Parfit argues that there are objective moral truths, and other normative truths about what we have reasons to believe, and to want, and to do. In defending his view, Parfit argues that if there are no objective normative truths, nihilism follows, and nothing matters. He criticizes many leading contemporary philosophers working on ethics, including Simon Blackburn, Stephen Darwall, Allen Gibbard, Frank Jackson, Peter Railton, Mark Schroeder, Michael Smith, and Sharon (...)

Does Anything Really Matter? gives these philosophers an opportunity to respond to Parfit, and includes essays by Richard Chappell, Andrew Huddleston, Katarzyna de Lazari-Radek and Peter Singer, Bruce Russell, and Larry Temkin. A third volume of On What Matters, in which Parfit engages with his critics and breaks new ground in finding significant agreement between his own views and theirs, is appearing as a separate companion volume.

In 1936, G. Birkhoff and J. v. Neumann published an article with the title The logic of quantum mechanics'. In this paper, the authors demonstrated that in quantum mechanics the most simple observables which correspond to yes-no propositions about a quantum physical system constitute an algebraic structure, the most important proper ties of which are given by an orthocomplemented and quasimodular lattice Lq. Furthermore, this lattice of quantum mechanical proposi tions has, from a formal point of view, many similarities with (...) a Boolean lattice L8 which is known to be the lattice of classical propositional logic. Therefore, one could conjecture that due to the algebraic structure of quantum mechanical observables a logical calculus Q of quantum mechanical propositions is established, which is slightly different from the calculus L of classical propositional logic but which is applicable to all quantum mechanical propositions. This calculus has sometimes been called 'quan tum logic'. However, the statement that propositions about quantum physical systems are governed by the laws of quantum logic, which differ from ordinary classical logic and which are based on the empirically well-established quantum theory, is exposed to two serious objec tions: Logic is a theory which deals with those relationships between various propositions that are valid independent of the content of the respective propositions. Thus, the validity of logical relationships is not restricted to a special type of proposition, e. g. to propositions about classical physical systems. (shrink)

Vanderschraaf develops a new theory of game theory equilibrium selection in this book. The new theory defends general correlated equilibrium concepts and suggests a new analysis of convention.

The world as we perceive it is structured into objects, actions and places that form parts of events. In this article, my aim is to explain why these categories are cognitively primary. From an empiricist and evolutionary standpoint, it is argued that the reduction of the complexity of sensory signals is based on the brain's capacity to identify various types of invariances that are evolutionarily relevant for the activities of the organism. The first aim of the article is to explain (...) why places, object and actions are primary cognitive categories in our constructions of the external world. It is shown that the invariances that determine these categories have their separate characteristics and that they are, by and large, independent of each other. This separation is supported by what is known about the neural mechanisms. The second aim is to show that the category of events can be analyzed as being constituted of the primary categories. The category of numbers is briefly discussed. Some implications for computational models of the categories are also presented. (shrink)

This article explores a framework for analyses of what has variously been termed the ‘implied’, ‘imagined’, ‘virtual’ or ‘putative’ reader/addressee – the effect by which ostensibly ‘monologic’ texts, such as news media commentary, political pronouncements and academic essays project particular attitudes, beliefs and expectations on to the reader/addressee. The framework is demonstrated in being applied to an examination of the construal of putative addressee positioning in a selection of mass media texts concerned with the Israeli military’s invasion of Gaza in (...) 2014. The framework is novel in the way in which it mobilises the account of the options for dialogistic positioning offered by the appraisal-framework literature, combined with some insights from Toulmin’s notion of the argumentative ‘warrant’. Conclusions are offered as to how such analyses of the readers being ‘written into the text’ can extend insights into the rhetorical workings of such texts and their ideological functionality in naturalising particular value positions.

For the modern-day jihadist, the digital self-portrait or, more specifically, battlefield selfie is a popular tool for identity building. Similarly to the selfies taken by non-violent practitioners of self-capture culture, the jihadist selfie represents an alternative to the Cartesian formulation of a unitary and indivisible self. Rather, it is a product of social relations and performative actions, constituted in dialogue with others through very specific socio-cultural frameworks and expectations. However, unlike its non-violent Doppelganger, the expectations of this dialogue are centred (...) around a larger political agenda which actively seeks to reformat collective memories of imperial Islamic conquests and co-opt religion as a way to impose a moral order on its violence. Importantly, the battlefield selfie allows the jihadist easily to traverse the boundaries between two seemingly opposing belief systems. Although there exists a wealth of scholarship of self-capture culture, image sharing sites and micro-celebritism, their pervasive influence and practice on battlefield is understudied. This article draws from the personal histories of key Islamic extremists who were both lionized and demonized as a result of their battlefield micro-influencer practices. Today, however, the same individuals can achieve internet fame by participating in self-capture culture – posting selfies, videos or blogging. In other words, never before has a soldier’s public communication been so personal yet collective. (shrink)

Despite considerable recent attention, important features of Schelling’s famous work, the 1809 treatise On the Essence of Human Freedom, remain under-explored. One of these is the methodological dualism which Schelling advocates at the very start of the text. Schelling aims to weld together into a coherent position a first-person phenomenology of freedom and an explanation achieved by locating freedom within a conceptual system articulating the basic structure of the world. Most interpretations of the Freiheitsschrift, however, concentrate on only one of (...) these approaches, thus foreshortening their understanding of Schelling’s enterprise. The article explores this tendency towards one-sidedness by considering two sophisticated recent interpretations of the work, taking opposite tacks. One, by Markus Gabriel, focuses on the distinctive, self-reflexive metaphysics which Schelling proposes, while the other, by Sebastian Gardner, claims that Schelling’s ontology is extrapolated entirely from his account of our moral consciousness, a procedure pioneered by Kant. The article argues that neither of these interpretations can do full justice to Schelling’s project. Furthermore, although the Freiheitsschrift is not entirely successful, and hence points towards later developments in Schelling’s thinking, its treatment of freedom is superior to the ‘soft naturalism’ pioneered by Peter Strawson, and currently influential across various philosophical traditions.

First published in 1998, this volume argues that two conditions need to be met for any agreement between people with conflicting desires to count as an unforced one, namely, that the parties argue as if they had equal power and that their antipathy to being coerced exceeds their desire to coerce others. These conditions entail objective moral principles and a theory of justice, modifying and developing Rawls' contractarian theory, but without the veil of ignorance. They support Rawls on basic civil (...) liberties and constitutional liberal democratic government, including religious tolerance, anti-paternalism, anti-racism and anti-sexism, but dispute his Difference Principle, his circumstances of justice, Laws of Peoples, reflective equilibrium, and freedom of conscience as a basic liberty. The book also gives a contractarian account of epistemology, metaethics, education, the rationality of being moral, the rights of animals and other non-persons, and the rights of indigenous peoples. Writers such as Brian Barry, R.S. Peters, Isaiah Berlin, Vinit Haksar, Jurgen Habermas, R.M. Hare, Philip Pettit, Derek Parfit, Michael Smith, Peter Geach, Philippa Foot, Bronwyn Davies, Quentin Skinner and Will Kymlicka are also discussed. (shrink)

There is presently a debate between Subjectivists and Objectivists about moral wrongness. Subjectivism is the view that the moral status of our actions, whether they are morally wrong or not, is grounded in our subjective circumstances – either our beliefs about, or our evidence concerning, the world around us. Objectivism, on the other hand, is the view that the moral status of our actions is grounded in our objective circumstances – all those facts other than those which comprise our subjective (...) circumstances. A third view, Ecumenism, has it that the moral status of our actions is grounded both in our subjective and our objective circumstances. After outlining and evaluating the various arguments both against Subjectivism and against Objectivism, this Element offers a tentative defense of Objectivism about moral wrongness. (shrink)

[1] In twelve quite demanding chapters, outstanding scholars provide an overall view of the key issues of Scotus’s philosophical thought. To this a very concise introduction is added, concerning the life and works of John Duns (very good, especially the survey of works and the information on critical editions etc.). Throughout the book, I find the information clear and the difficult topics well explained. Moreover, the volume gives a quick entrance to the vast literature. Among the topics discussed are: ‘Metaphysics’ (...) (Peter King), ‘Universals and Individuation’ (Timothy Noone), ‘Modal Theory’ (Calvin Normore), ‘Natural Theology’ (James Ross & Todd Bates), ‘Philosophy of Mind’ (Richard Cross), ‘Cognition’ (Robert Pasnau), ‘Moral Dispositions’ (Bonnie Kent). What strikes the eye is the absence of important theological subjects: Trinity, Christology, sin and grace, to name a few. Since the cover text promises that ‘the essays in this volume systematically survey the full range of Scotus’ thought’, this omission is remarkable. It stems, I guess, from the strict philosophical scope of the series of the Cambridge Companions, but such a limitation should have been recognised explicitly: this companion provides, in fact, an introduction to John Duns’s philosophy—i.e., philosophy in our modern sense. Of course, this separation of philosophical from theological thought is not from Scotus. Most of his innovative ‘philosophical’ ideas are developed in a profoundly theological context! (shrink)

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social norms as a partial explanation for the reliability of testimony.
