The value of testimony as a source of knowledge has been a subject of epistemological debates. The "trust theory of testimony" suggests that human testimony is based on an affective relationship supported by social norms. However, the advent of generative artificial intelligence challenges our understanding of genuine testimony. The concept of "quasi-testimony" seeks to characterize utterances produced by non-human entities that mimic testimony but lack certain fundamental attributes. This article analyzes these issues in (...) depth, exploring philosophical perspectives on testimony and the implications of conversational AI technologies on our epistemic practices. (shrink)

Two key intuitions regarding knowledge are explored: that knowledge is a kind of cognitive achievement and that knowledge excludes luck. It is claimed that a proper understanding of how these intuitions should inform our conception of knowledge leads to some surprising results, not just as regards the theory of knowledge more generally but also as regards the epistemology of testimonial knowledge. In particular, it is argued that this conception of knowledge motivates a new kind of proposal B quasi-reductionism B (...) that can accommodate the motivations behind both reductionist and anti-reductionist accounts of the epistemology of testimonial knowledge.

Aesthetic judgements are autonomous, as many other judgements are not: for the latter, but not the former, it is sometimes justifiable to change one's mind simply because several others share a different opinion. Why is this? One answer is that claims about beauty are not assertions at all, but expressions of aesthetic response. However, to cover more than just some of the explananda, this expressivism needs combining with some analogue of cognitive command, i.e. the idea that disagreements over beuaty can (...) occur, and when they do it is a priori that one side has infringed the norms governing aesthetic discourse. This combination can be achieved by reading Kant’s aesthetic theory in expressivist terms. The resulting view is a form of quasi-realism about beauty. The position has its merits, but cannot ultimately explain the phenomena which motivate it. This conclusion generalises to quasi-realism about other matters. (shrink)

Drawing on both empirical evidence and evolutionary considerations, Sperber et al. argue that humans have a suite of evolved mechanisms for . On their view, vigilance plays a crucial role in ensuring the reliability and hence the evolutionary stability of communication. This article responds to their argument for vigilance, drawing on additional empirical evidence (from deception detection research) and evolutionary considerations (from animal signalling research) to defend a more optimistic, quasi-Reidian view of communication. On this alternative view, the lion's (...) share of the responsibility for explaining the reliability of testimony falls not to the vigilance of receivers but rather to the honesty of communicators, implying that vigilance does not play a major role in explaining the evolutionary stability of communication.

The starting point of this article is a surprising finding about Ricœur’s Time and Narrative. This impressive trilogy – essentially dedicated to the narrative and its capacity to refigure time, often defined as a poetics of history, laying the basis of the theory of narrative identity – barely considers the phenomenon of the testimony, generally understood as someone’s narration about a past event. But suspecting a paradoxical lacuna in the problematic of Time and Narrative doesn’t exempt us from searching (...) its ‘reasons’. Thus, in the first part of this paper, we’ll take into account, from a genealogical point of view, Ricœur’s article on the hermeneutics of the testimony, written few years before his trilogy. In the second part, the questioning of what we’ve called the quasi-absence of the testimony in Time and Narrative will involve keen analysis of the theories concerning the reality of the past determined according to different criteria: proximity / observation versus pertinence / possibility.

There is an existing debate regarding the view that technological instruments, devices, or machines can assert ‎or testify. A standard view in epistemology is that only humans can testify. However, the notion of quasi-‎testimony acknowledges that technological devices can assert or testify under some conditions, without ‎denying that humans and machines are not the same. Indeed, there are four relevant differences between ‎humans and instruments. First, unlike humans, machine assertion is not imaginative or playful. Second, ‎machine assertion is (...) prescripted and context restricted. As such, computers currently cannot easily switch ‎contexts or make meaningful relevant assertions in contexts for which they were not programmed. Third, ‎while both humans and computers make errors, they do so in different ways. Computers are very sensitive to ‎small errors in input, which may cause them to make big errors in output. Moreover, automatic error control ‎is based on finding irregularities in data without trying to establish whether they make sense. Fourth, ‎testimony is produced by a human with moral worth, while quasi-testimony is not. Ultimately, the notion of ‎quasi-testimony can serve as a bridge between different philosophical fields that deal with instruments and ‎testimony as sources of knowledge, allowing them to converse and agree on a shared description of reality, ‎while maintaining their distinct conceptions and ontological commitments about knowledge, humans, and ‎nonhumans.‎.

According to widely accepted views in metasemantics, the outputs of chatbots and other artificial text generators should be meaningless. They aren’t produced with communicative intentions and the systems producing them are not following linguistic conventions. Nevertheless, chatbots have assumed roles in customer service and healthcare, they are spreading information and disinformation and, in some cases, it may be more rational to trust the outputs of bots than those of our fellow human beings. To account for the epistemic role of chatbots (...) in our society, we need to reconcile these observations. This paper argues that our engagement with chatbots should be understood as a form of prop-oriented make-believe; the outputs of chatbots are literally meaningless but fictionally meaningful. With the make-believe approach, we can understand how chatbots can provide us with knowledge of the world through quasi-testimony while preserving our metasemantic theories. This account also helps to connect the study of chatbots with the epistemology of scientific instruments. (shrink)

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or (...) even let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

This article defends the thesis that the reflection which Ricœur conducts on the notion of testimony is not one research topic among others, but forms one of the keys to understanding the Ricœurian project as such. The notion of testimony enables one to get beyond the polarity of description and ascription, in order to return to the question of the real. Through an examination of the quadruple grammar of testimony that Ricœur proposes and its context in the (...) dialogue with historiography and theology, the article advances the thesis that with testimony, we broach the limit point of hermeneutics, a “non-interpretable” at the heart of interpretation. This “non-interpretable” acquires a quasi-transcendental status, because it allows interpretation to broach the thing it is dealing with and not another interpretation. Lastly, it will be important to show how Ricœur’s thought on testimony also reflects an ethics: this ethics prohibits treating the testimony as a mere source, referring to a positivity, but as a trace, within an experience, which as such is unrepeatable.

Recently, Kant’s account of aesthetic autonomy has received attention from those interested in a range of issues in aesthetics, including the subjectivity of aesthetic judgment, quasi-realism, aesthetic testimony, and aesthetic normativity. Although these discussions have shed much light on the implications of Kant’s account of aesthetic autonomy, the phenomenon of aesthetic autonomy itself tends to be under-described. Commentators often focus on the negative aspect of this phenomenon, i.e., the sense in which an aesthetic judgment cannot be grounded on (...) the testimony of others. However, on Kant’s view, autonomy is a positive phenomenon, something that involves self-determination and self-legislation. My aim in this paper is to clarify this positive aspect of Kantian aesthetic autonomy. In order to defend my interpretation of aesthetic autonomy, I appeal to another key concept in Kant’s aesthetics, viz., ‘common sense’. I claim that, for Kant, aesthetic common sense, which we acquire through aesthetic education, is what makes aesthetic self-determination and self-legislation, hence aesthetic autonomy, possible.

Background: The recent COVID-19 pandemic has highlighted the deficiencies that characterize the functioning of the Italian national health system. Prisons have always mirrored the most radical expressions of these weaknesses. During the early stages of the pandemic, prison facilities across Italy underwent a series of changes dictated by the need to ensure the safety of the prisoners and staff. The adoption of these rules contributed to a total or partial redefinition of many central facets of life in prison, such as (...) intake procedures for new arrivals and the ways prisoners were allowed to communicate with their families.Objectives: The aim of this qualitative study was to analyze the testimony of penitentiary healthcare workers in prisons throughout Italy to determine the impact of COVID-19 on their professional and personal lives.Participants: Thirty-eight participants were contacted and 20 decided to participate in the interview. The sample was made up of 10 women and 10 men. All the participants were members of the healthcare staff of a penitentiary facility. All were recruited through an Italian association whose mission is the development, promotion, and implementation of social solidarity projects including prisoners' social and health care. This study was facilitated through representatives serving in nine different regions of Italy. The participants were divided according to their professional roles in prisons.Method: In-depth interviews were conducted by telephone or online using telecommunication platforms. The transcribed texts underwent thematic analysis using the Atlas.ti software to identify patterns of meaning across the dataset.Results: Four main themes emerged from the analysis: Interpersonal difficulties, management and operational difficulties, the personal distress and bereavement of healthcare workers, and the distress of inmates. The importance of relationship management skills when interacting with prisoners emerged as a key topic in many interviews, and the participants highlighted the need for adequate training. The increase in prisoners' anxiety made communication more difficult.Conclusions: The findings suggest that healthcare workers in jails need emergency-oriented training. Participants described their feeling of loneliness and quasi-abandonment when carrying out their duties during the pandemic. In particular, they underscored the need for psychological guidance to better manage altered reactions with prisoners and colleagues as a result of heightened death anxiety and isolation. (shrink)

Four arguments are examined in order to assess the state of the Intelligent Design debate. First, critics continually cite the fact that ID proponents have religious motivations. When used as criticism of ID arguments, this is an obvious ad hominem. Nonetheless, philosophers and scientists alike continue to wield such arguments for their rhetorical value. Second, in his expert testimony in the Dover trial, philosopher Robert Pennock used repudiated claims in order to brand ID as a kind of pseudoscience. His (...) arguments hinge on the nature of methodological naturalism as a metatheoretic shaping principle. We examine the use of such principles in science and the history of science. Special attention is given to the demarcation problem. Third, the scientific merits of ID are examined. Critics rightly demand more than promissory notes for ID to move beyond the fringe. Fourth, although methodological naturalism gets a lot of attention, there is another shaping principle to contend with, namely, conservatism. Science, like most disciplines, tends to change in an incremental rather than revolutionary manner. When ID is compared to other non- or quasi-Darwinian proposals, it appears to be a more radical solution than is needed in the face of the anomalies. (shrink)

Among the reconstructions of the quasi-legendary figure of Pherecydes, one point of the doxography concerning possible astronomical activities of the Wise of Syros is quickly dismissed by modern commentators. The story is based on two testimonies reported by Diogenes Laertius: one attributes to Pherecydes the invention of an instrument for observing the solstices (the “heliotrope”); the other recalls the opinion of Andron of Ephesus, who distinguished between two Pherecydes of Syros: the “Wise” and the “astronomer”. The first seems to (...) stem from a misunderstanding of Homeric poetry ; the second, if derived from the former, would have no greater value. However, the various understandings of the testimonies of Diogenes Laertius on Andron and, immediately after him, on Eratosthenes, leave open the possibility that the general issue of Pherecydes’ astronomy implied more than a simple misunderstanding of a few Homeric verses (without excluding it). It could rather depend on: (a) the confusion over the identity of Pherecyde(s) that seems to have prevailed as early as the 4th century B.C.; (b) the philosophical character that earlier doxographers were willing to attribute to his work. These neglected testimonies then became a remarkable source of information on the first reception of Pherecydes of Syros in the 4th century B.C., and on the ways in which this thinker was integrated in the history of philosophy.

Le témoignage a retenu de très près l’herméneutique philosophique de Paul Ricœur. De son sens quasi empirique, celui du témoin d’un procès, à sa signification religieuse, celle du témoin de la foi, en passant par sa signification morale, le témoin vit du bien dont il témoigne. Se trouvant donc au croisement du juridique, de l’historique, de l’éthique et du religieux, le témoignage trouve, dans les analyses de Paul Ricœur, son principe unificateur dans le concept d’identité narrative. J.-Ph. Pierron montre (...) que pour le philosophe de Temps et récit, le témoignage dans le témoin est texte. Il donne donc à penser, ce qui implique une herméneutique de la réception, axée sur l’analyse d’un accueil du témoignage. Corrélativement, parler d’identité narrative, c’est donner l’occasion au témoignage de passer insensiblement d’un pôle d’extériorité, celui du narrateur qui n’est pas l’acteur de ce qu’il raconte, à un pôle d’intériorité, qui fait constitution progressive de soi. En quoi doit se définir une éthique du témoignage. Bearing witness is a very important concept in the philosophical hermeneutic of Paul Ricoeur. From its quasi-empirical meaning, that of the testimony of a witness in a trial, to its religious significance, that of a witness to the faith, and its moral significance, the witness lives from the good to which he bears witness. Bearing witness, which lies at the core of legal, historical, ethical, and religious testimony, finds its unifying principle in the analysis of Paul Ricoeur in the concept of narrative identity. J.-P. Pierron shows that, for the philosopher of Time and Narrative, the testimony of the witness becomes text in the one who bears witness. Thus, it leads to thinking, which implies a hermeneutic of receiving, centered on the analysis of how testimony from a witness is received. Correlatively, to speak of narrative identity is to give an opportunity for bearing witness to move imperceptibly from a position of exteriority, that of a narrator who is not the actor of that which he recounts, to a position of interiority, which makes for a progressive constitution of the self. This ought to define an ethic of bearing witness. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:In Their Father’s Library: Books Furnish Not Only a Room, But Also a Tradition ELIZABETH POWERS Although they shared close life dates and became famous in the same years for their epistolary novels, Johann Wolfgang von Goethe (1749–1832) and Fanny Burney (1752–1840) would seem to have been worlds apart literarily. (Goethe had in his Weimar library a copy of Evelina, while Burney was probably not ignorant of the Europe-wide (...) sensation The Sorrows ofYoung Werther.) What might be called their literary apprenticeship, however, was remarkably similar, consisting not of schooling in a traditional institution in which students (and, importantly, most eighteenth-century writers) were drilled in the classical curriculum, but, instead, from wide reading within the confines of their fathers’ libraries. It is true that Goethe and his younger sister Cornelia were supplied at home with a number of tutors and that their progress was monitored by their father, but their acquaintance with literature was fostered within the confines of the family home. Burney had no formal education at all. Indeed, on the appearance of Evelina, her father (according to her diary) remarked : “[S]he has had very little Education but what she has given herself,—less than any of the others!” Burney, however, had the advantage of growing up in a milieu in which books mattered. While the Goethes were eminently respectable, on the mother’s side part of what was the patriciate of the city of Frankfurt, the Burney household in London was bursting with wits and with what can only be called celebrities. The Burneys knew God and the world: David Garrick, Dr. Johnarion 28.1 spring/summer 2020 116 in their father’s library son, Hester Thrale. As Virginia Woolf noted of the famous father, Dr. Charles Burney, he was a musician “who could talk of intellectual things and ask clever people to his house.” Goethe has given plenty of evidence of roaming freely among his father’s books, a collection of 1,700 calfskin-bound volumes. When Burney went to serve at the court of King George III, Queen Charlotte was disappointed at how few books the author of Evelina possessed. (Similarities accumulate: Goethe also served at court, as minister in the duchy of Weimar.) But why cart around a load of books? As Burney wrote in her diary: “[M]y Father’s most delightful Library, as I then told her [the Queen], with my free access to it, had made [owning my own books] a thing unnecessary... ” Libraries in the eighteenth and early nineteenth century, whether private or public affairs, were not like contemporary public libraries, catering to a wide array of tastes, but were repositories of what Matthew Arnold termed “the best that is known and thought in the world.” Let’s call it the Western intellectual and cultural heritage. Most respectable homes would possess at a minimum a Bible, while the holdings in private homes, as evident in the library of Goethe’s father, could reach astounding proportions. According to Burney biographer Claire Harman, Fanny’s brother left at his death one of the finest private libraries of the age. Moreover, the antiquity of the works in the venerable libraries scattered across Europe from Dublin to Saint Petersburg, and especially their survival despite centuries of vicissitudes, was testimony to the authoritative nature of the transmission. Anyone who took the Bible in hand, who took lessons from it, adhering, for instance, to the injunctions of the Ten Commandments, was conscious of subscribing to values shared by preceding generations. Literary practitioners, also showing obeisance to authoritative predecessors, followed earlier models, in the process contributing to an evolving literary heritage. There was no purity in this transmission. It was truly promiscuous, but its quasi-biological character, like a mother’s left-handedness in a child, can be seen in the family Elizabeth Powers 117 resemblances among writers of different eras. Just as individuals perpetuate traits of their parents, so literature and the other arts recycled features of artistic predecessors. Writers as diverse in background and language and religion as Ariosto and Milton transmitted the dna, so to speak, of such epical forebears as Homer and Virgil. This sort of family legitimacy was...

This paper analyses the phenomenology and epistemology of chatbots such as ChatGPT and Bard. The computational architecture underpinning these chatbots are large language models (LLMs), which are generative artificial intelligence (AI) systems trained on a massive dataset of text extracted from the Web. We conceptualise these LLMs as multifunctional computational cognitive artifacts, used for various cognitive tasks such as translating, summarizing, answering questions, information-seeking, and much more. Phenomenologically, LLMs can be experienced as a “quasi-other”; when that happens, users anthropomorphise (...) them. For most users, current LLMs are black boxes, i.e., for the most part, they lack data transparency and algorithmic transparency. They can, however, be phenomenologically and informationally transparent, in which case there is an interactional flow. Anthropomorphising and interactional flow can, in some users, create an attitude of (unwarranted) trust towards the output LLMs generate. We conclude this paper by drawing on the epistemology of trust and testimony to examine the epistemic implications of these dimensions. Whilst LLMs generally generate accurate responses, we observe two epistemic pitfalls. Ideally, users should be able to match the level of trust that they place in LLMs to the degree that LLMs are trustworthy. However, both their data and algorithmic opacity and their phenomenological and informational transparency can make it difficult for users to calibrate their trust correctly. The effects of these limitations are twofold: users may adopt unwarranted attitudes of trust towards the outputs of LLMs (which is particularly problematic when LLMs hallucinate), and the trustworthiness of LLMs may be undermined.

The Greek geographer Strabo described Moses as a charismatic leader who had instilled in his followers a simple form of worship and an unconventional form of government. Subsequent generations of Moses’s successors had exploited people’s awe of the sacred, however, in order to erect a superstitious and tyrannical hierocracy. John Toland’s Origines Judaicae (1709) relied heavily on Strabo’s testimony in its denunciation of superstition and priestcraft. Strabo’s passage on Moses was well known, not only to Toland but to Christian (...) apologists who – since the sixteenth century – had used it to defend the account of Moses in the Old Testament. Yet, by the eighteenth century, Strabo had been transformed from a quasi-Christian authority into a historical liability to orthodoxy. Attending to the often-neglected reception of Strabo, this article uncovers continuities and discontinuities in ideas of superstition and priestcraft through the writings of Isaac Casaubon, Philippe de Mornay, Hugo Grotius, and John Toland. It argues that the reception of Strabo in the early modern period demonstrates how his Geography became increasingly caught in the crossfire of religious controversy. (shrink)

The figure of Socrates divides the history of Western thought into two parts. It inaugurates a model of philosophy that shaped all subsequent tradition with the sole force of its influence and the totemic aura from his tragic death. There were many accounts of what happened, but none of them overshadowed Plato's Apology of Socrates as a fundamental text for entering into the details of the trial and sentence. In this context, the opacity of this text is rarely taken into (...) account. It seems to be a testimonial document, a quasi-stenographic version of the process, but it is not. In fact, we are interested in referring to a fact that has been noted but not entirely dimensioned: Plato's Apology of Socrates presents similarities impossible to attribute to mere chance with Gorgias’ Apology of Palamedes. Why does this Platonic text present curious intertextual relationships with a rhetorical exercise based on mythical figures in the climate of the promotion of rhetoric? We will try to answer this question appealing to its link with the origin of the Socratic dialogue. (shrink)

Expressivism is the view that the function of normative sentences is not to represent a kind of fact, but to avow attitudes, prescribe behavior, or the like. The idea can be found in David Hume. In the 20th century, G.E. Moore’s Open Question Argument provided important support for the view. Elizabeth Anscombe introduced the notion of “direction of fit,” which helped distinguish expressivism from a kind of naive subjectivism. The central advantage of expressivism is that it easily explains the motivational (...) force of moral conviction. Its chief problem is it has difficulty explaining the “realist surface” of moralizing. Quasi-realism is a strategy for explaining the realist surface without abandoning the underlying ideas of expressivism. It aims to explain moral error as well as deal with the so-called Frege-Geach problem. This chapter explains quasi-realism, and evaluates it by comparison with its chief rivals: Aristotelian approaches, Kantian approaches, realist moral naturalism, and fictionalism. (shrink)

This volume collects some influential essays in which Simon Blackburn, one of our leading philosophers, explores one of the most profound and fertile of philosophical problems: the way in which our judgments relate to the world. This debate has centered on realism, or the view that what we say is validated by the way things stand in the world, and a variety of oppositions to it. Prominent among the latter are expressive and projective theories, but also a relaxed pluralism that (...) discourages the view that there are substantial issues at stake. The figure of the "quasi-realist" dramatizes the difficulty of conducting these debates. Typically philosophers thinking of themselves as realists will believe that they alone can give a proper or literal account of some of our attachments--to truth, to facts, to the independent world, to knowledge and certainty. The quasi-realist challenge, developed by Blackburn in this volume, is that we can have those attachments without any metaphysic that deserves to be called realism, so that the metaphysical picture that goes with our practices is quite idle. The cases treated here include the theories of value and knowledge, modality, probability, causation, intentionality and rule-following, and explanation. A substantial new introduction has been added, drawing together some of the central themes. The essays articulate a fresh alternative to a primitive realist/anti-realist opposition, and their cumulative effect is to yield a new appreciation of the delicacy of the debate in these central areas.

Is there a problem with believing based on moral testimony? The intuition that there is a problem is a starting point for much research on moral testimony.

The study confirms an asymmetry in the way we think about testimony about moral and descriptive matters and explores the extent to (...) which this asymmetry is explained by different metaphysical beliefs about the relevant domains, or beliefs about the relative background levels of deception or disagreement.

Many philosophers believe that aesthetic testimony can provide aesthetic knowledge. This leaves us with the question: why does getting aesthetic knowledge by experience – by seeing a painting up close, or witnessing a performance first-hand – nevertheless seem superior to aesthetic testimony? I argue that it is due to differences in their epistemic value; in the diversity of epistemic goods each one provides. Aesthetic experience, or the experience of art or other aesthetic objects, affords multiple, distinctive epistemic goods (...) whereas aesthetic testimony affords less. In particular, it provides aesthetic knowledge of truths, a kind of propositional knowledge, as well as aesthetic knowledge of things, a kind of non-propositional knowledge. Although aesthetic experience is superior because it has more epistemic value, this doesn’t mean that aesthetic testimony provides weaker justification for aesthetic belief than aesthetic experience; the difference is evaluative, not normative. In this way, we can explain a key pessimistic intuition about aesthetic testimony – that it is inferior to aesthetic experience – whilst preserving the optimistic view that aesthetic testimony makes aesthetic knowledge available to others. The superior epistemic value of first-hand aesthetic experience is compatible with a number of important observations about aesthetic testimony, including the importance of aesthetic trust. (shrink)

Kant claims that the judgement of taste, the judgement that some particular is beautiful, exhibits two ‘peculiarities’. First: [t]he judgement of taste determines its object in respect of delight with a claim to the agreement of every one , just as if it were objective.

A testimony is somebody else’s reported experience of what has happened. It is an indispensable source of knowledge. It only gives us historical cognition, however, which stands in a complex relation to rational or philosophical cognition: while the latter presupposes historical cognition as its matter, one needs the architectonic “eye of a philosopher” to select, interpret, and organize historical cognition. Kant develops this rationalist theory of testimony. He also practices it in his own work, especially while theorizing about (...) race as a subject of natural philosophy. In three dedicated essays on this subject, he treats race from the standpoint of a philosophical investigator of nature (Naturforscher), who (as Kant puts it in the first Critique) learns from nature “like an appointed judge who compels witnesses to answer the questions he puts to them.” This view underwrites Kant’s use of travel reports (a type of testimony) in developing and defending his theory of race.

Call the view that it is possible to acquire aesthetic knowledge via testimony, optimism, and its denial, pessimism. In this paper, I offer a novel argument for pessimism. It works by turning attention away from the basis of the relevant belief, namely, testimony, and toward what that belief in turn provides a basis for, namely, other attitudes. In short, I argue that an aesthetic belief acquired via testimony cannot provide a rational basis for further attitudes, such as (...) admiration, and that the best explanation for this is that the relevant belief is not itself rational. If a belief is not rational, it is not knowledge. So, optimism is false. After addressing a number of objections to the argument, I consider briefly its bearing on the debate concerning thick evaluative concepts. While the aim is to argue that pessimism holds, not to explain why it holds, I provide an indication in closing of what that explanation might be. (shrink)

Teaching is not testimony. Although both convey information, they have different uptake requirements. Testimony aims to impart information and typically succeeds if the recipient believes that informationon account of having been told by a reliable informant. Teaching aims to equip learners to go beyond the information given—to leverage that information to broaden, deepen, and critique their current understanding of a topic. Teaching fails if the recipients believe the information only because it is what they have been told.

Critics of virtue reliabilism allege that the view cannot account for testimonial knowledge, as the acquisition of such knowledge is creditable to the testifier, not the recipient's cognitive abilities. I defend virtue reliabilism by attending to empirical work concerning human abilities to detect sincerity, certainty, and seriousness through bodily cues and properties of utterances. Then, I consider forms of testimony involving books, newspapers, and online social networks. I argue that, while discriminatory abilities directed at bodily cues and properties of (...) utterances are impotent in the face of such testimony, alternative abilities facilitate the acquisition of knowledge from these sources.

Speaking with conversational AIs, technologies whose interfaces enable human-like interaction based on natural language, has become a common phenomenon. During these interactions, people form their beliefs due to the say-so of conversational AIs. In this paper, I consider, and then reject, the concepts of testimony-based beliefs and instrument-based beliefs as suitable for analysis of beliefs acquired from these technologies. I argue that the concept of instrument-based beliefs acknowledges the non-human agency of the source of the belief. However, the analysis (...) focuses on perceiving signs and indicators rather than content expressed in natural language. At the same time, the concept of testimony-based beliefs does refer to natural language propositions, but there is an underlying assumption that the agency of the testifier is human. To fill the lacuna of analyzing belief acquisition from conversational AIs, I suggest a third concept: technology-based beliefs. It acknowledges the non-human agency-status of the originator of the belief. Concurrently, the focus of analysis is on the propositional content that forms the belief. Filling the lacuna enables analysis that considers epistemic, ethical, and social issues of conversational AIs without excluding propositional content or compromising accepted assumptions about the agency of technologies.

This paper surveys some ways of distinguishing Quasi-Realism in metaethics from Non-naturalist Realism, including ‘Explanationist’ methods of distinguishing, which characterize the Real by its explanatory role, and Inferentialist methods. Rather than seeking the One True Distinction, the paper adopts an irenic and pragmatist perspective, allowing that different ways of drawing the line are best for different purposes.

ABSTRACT Testimony from victims of gendered violence is often wrongly disbelieved. This paper explores a way to address this problem by developing a phenomenological approach to testimony. Guided by the concept of ‘disclosedness’, a tripartite analysis of testimony as an affective, embodied, communicative act is developed. Affect indicates how scepticism may arise through the social moods that often attune agents to victims’ testimony. The embodiment of meaning suggests testimony should not be approached as an assertion, (...) but as a process of ‘articulating an understanding’. This account is deepened in the discussion of testimony as a communicative act. It is argued that testimony must be considered as a relational whole, and thus our aim in receiving victims’ testimony should be to honour the relational conditions under which the truth of testimony can be heard. Approaching testimony as the collaborative process of enabling an understanding to be articulated can enhance our conception of gendered violence, whilst also better serving the victims of gendered violence by helping to overcome the lack of trust and excessive scepticism with which victims’ testimony is often met.

Jonathan Cohen has claimed that in cases of witness agreement there is an inverse relationship between the prior probability and the posterior probability of what is being agreed: the posterior rises as the prior falls. As is demonstrated in this paper, this contention is not generally valid. In fact, in the most straightforward case exactly the opposite is true: a lower prior also means a lower posterior. This notwithstanding, there is a grain of truth to what Cohen is saying, as (...) there are special circumstances under which a thesis similar to his holds good. What characterises these circumstances is that they allow for the fact of agreement to be surprising. In making this precise, I draw on Paul Horwich's probabilistic analysis of surprise. I also consider a related claim made by Cohen concerning the effect of lowering the prior on the strength of corroboration. 1 Introduction 2 Cohen's claim 3 A counterexample 4 A weaker claim 5 A counterexample to the weaker claim 6 The grain of truth in Cohen's claim 7 Prior probability and strength of corroboration 8 Conclusion.

Two intuitionistic paradefinite logics N4C and N4C+ are introduced as Gentzen-type sequent calculi. These logics are regarded as a combination of Nelson’s paraconsistent four-valued logic N4 and Wansing’s basic constructive connexive logic C. The proposed logics are also regarded as intuitionistic variants of Arieli, Avron, and Zamansky’s ideal paraconistent four-valued logic 4CC. The logic N4C has no quasi-explosion axiom that represents a relationship between conflation and paraconsistent negation, but the logic N4C+ has this axiom. The Kripke-completeness and cut-elimination theorems (...) for N4C and N4C+ are proved. (shrink)

I discuss several views of the nature of testimony and show how each proposal has importantly different problems. I then offer a diagnosis of the widespread disagreement regarding this topic; specifically, I argue that our concept of testimony has two different aspects to it. Inadequate views of testimony, I claim, result either from collapsing these two aspects into a single account or from a failure to recognize one of them. Finally, I develop an alternative view of (...) class='Hi'>testimony that captures both aspects of the nature of testimony and thereby provides the basis for an illuminating theory of testimony's epistemological significance.

Since the Restitution of Land Rights Act 22 of 1994 came into operation, courts have come to attach considerable significance to historian expert testimony when ruling on land claims that made it to court. Therefore, a universal approach had to be adopted. Over the years the Supreme Court of Appeal and Constitutional Court have developed tried and tested methodologies to aid the courts in determining the weight and admissibility of a witness' testimony. In the Salem Commonage case, both (...) the Land Claims Court and the majority of the Supreme Court of Appeal deviated from these precedents by adopting arguably a broader interpretation of the Act than intended. The case is unique in the sense that the dispute involves a commonage that was subdivided via a court order in 1940, resulting in the removal of the remaining black African population from that land. The question therefore was whether or not this group of people fulfilled the requirements for a valid claim as set out in the Act. The Land Claims Court and Supreme Court of Appeal felt that it had. The landowners applied for leave to appeal to the Constitutional Court. The application was granted, but in his judgment, Edwin Cameron agreed with the rationale of both courts, and held that there was a valid claim. This was despite the fact that the testimony of the claimants' 'star witness', Msile Nondzube, was heavily criticised by the landowners as well as a Supreme Court of Appeal judge. The Constitutional Court emphasised that the Act was an extraordinary piece of legislation and had to be interpreted in such a way so as to address the injustices of the past. This included provisions of the Act which dealt with how oral and expert evidence would be dealt with. (shrink)

This interview with the philosopher Bernard Stiegler was conducted in Paris on 28 January 2015, and first appeared in Dutch translation in the journal De uil van Minerva. The conversation begins by discussing the fundamental place occupied by the concept of ‘technics’ in Stiegler’s work, and how the ‘constitutivity’ of technics does and does not relate to Kant and Husserl. Stiegler is then asked about his relationship with Deleuze, and he responds by focusing on the concept of quasi-causality, but (...) also by arguing that there is a certain trajectory in Deleuze’s thought, situating his own philosophy in relation to its various moments. Stiegler is then asked to respond to the Charlie Hebdo terrorist attacks carried out three weeks prior to the interview. After making a couple of precautionary remarks, Stiegler relates such occurrences to the problem of what he calls ‘spiritual poverty’, to the intensification of ‘negative sublimation’ that can occur when there is a disconnection between the generations, and more generally to the growth of nihilism. All of these phenomena relate to the exploitation of technology by a virulent capitalism that irrationally believes that only the market is rational. After consideration of the complex historical relationship between Islam and modernization, and of both of these to Nietzsche’s ‘death of God’, and after recalling the destructive role played by the West in the rise of fundamentalism and jihadism, Stiegler concludes by reflecting on the fact that, ultimately, ‘intellectuals’ have failed to use technologies in ways that produce alternatives to consumerism.

As past research has identified frontline employees as the primary communicators of a company’s CSR, this paper reports on a large-scale quasi-field experiment aimed at gaining a deeper understanding of the levers of successful in-store, point-of-sale, CSR communication. In cooperation with a large international retailer, the authors analyzed the effects of varying in-store CSR communication strategies in 48 unique stores, combining data from a customer survey, company records of customers’ real visits and purchases, and interviews with store managers. Taking (...) into account the nested structure of the data, the authors reveal that CSR-related training of frontline employees bestows its favorable effect on customers and customer behavior only if it is accompanied by the store managers’ personal support for CSR.

An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make (...) ad hominem fallacies seem effective, even when the irrelevance is recognized. (shrink)
