According to some theories of testimonial knowledge, testimony can allow you, as a knowing speaker, to transmit your knowledge to me. A question in the epistemology of testimony concerns whether or not the acquisition of testimonial knowledge depends on the speaker's testimony being sincere. In this paper, I outline two notions of sincerity and argue that, construed in a certain way, transmission theorists should endorse the claim that the acquisition of testimonial knowledge requires sincerity.

This article develops a social epistemological analysis of Web-based search engines, addressing the following questions. First, what epistemic functions do search engines perform? Second, what dimensions of assessment are appropriate for the epistemic evaluation of search engines? Third, how well do current search engines perform on these? The article explains why they fulfil the role of a surrogate expert, and proposes three ways of assessing their utility as an epistemic tool—timeliness, authority prioritisation, and objectivity. “Personalisation” is a current trend in (...) Internet-delivered services, and consists in tailoring online content to the interests of the individual user. It is argued here that personalisation threatens the objectivity of search results. Objectivity is a public good; so there is a prima facie case for government regulation of search engines. (shrink)

Neste ensaio, eu analisarei criticamente três definições de boato. Na primeira seção, eu considerarei a explicação de C. A. J. Coady, na qual o boato é um caso de testemunho aparente, mas não é um caso de testemunho genuíno. Na segunda seção, eu considerarei a definição de boato oferecida por David Coady, na qual o boato se espalha em uma larga cadeia sem status oficial. Na terceira seção, eu considerarei a definição de boato de Axel Gelfert, na qual o boato (...) não tem corroboração independente de evidência de primeira mão ou de fonte oficial. Na quarta e última seção, eu proporei uma definição, na qual o boato é um caso de testemunho genuíno sem confirmação oficial, cuja fonte original foi perdida ou nunca existiu. (shrink)

The COVID-19 pandemic has been accompanied on social media by an explosion of information disorders such as inaccurate, misleading and irrelevant information. Countermeasures adopted thus far to curb these informational disorders have had limited success because these did not account for the diversity of informational contexts on social media, focusing instead almost exclusively on curating the factual content of user’s posts. However, content-focused measures do not address the primary causes of the infodemic itself, namely the user’s need to post content (...) as a way of making sense of the situation and for gathering reactions of consensus from friends. This paper describes three types of informational context—weak epistemic, strong normative and strong emotional—which have not yet been taken into account by current measures to curb down the informational disorders. I show how these contexts are related to the infodemic and I propose measures for dealing with them for future global crisis situations. (shrink)

This article explores the norms that govern regular users’ acts of sharing content on social networking sites. Many debates on how to counteract misinformation on Social Networking Sites focus on the epistemic norms of testimony, implicitly assuming that the users’ acts of sharing should fall under the same norms as those for posting original content. I challenge this assumption by proposing a non-epistemic interpretation of (mis) information sharing on social networking sites which I construe as infrastructures for forms of life (...) found online. Misinformation sharing belongs more in the realm of rumour spreading and gossiping rather than in the information-giving language games. However, the norms for sharing cannot be fixed in advance, as these emerge at the interaction between the platforms’ explicit rules, local norms established by user practices, and a meta-norm of sociality. This unpredictability does not leave us with a normative void as an important user responsibility still remains, namely that of making the context of the sharing gesture explicit. If users will clarify how their gestures of sharing are meant to be interpreted by others, they will implicitly assume responsibility for possible misunderstandings based on omissions, and the harms of shared misinformation can be diminished.

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.

Rumors, for better or worse, are an important element of public discourse. The present paper focuses on rumors as an epistemic phenomenon rather than as a social or political problem. In particular, it investigates the relation between the mode of transmission and the reliability, if any, of rumors as a source of knowledge. It does so by comparing rumor with two forms of epistemic dependence that have recently received attention in the philosophical literature: our dependence on the testimony of others, (...) and our dependence on what has been called the ‘coverage-reliability’ of our social environment (Goldberg 2010). According to the latter, an environment is ‘coverage-reliable’ if, across a wide range of beliefs and given certain conditions, it supports the following conditional: If ~p were true I would have heard about it by now. However, in information-deprived social environments with little coverage-reliability, rumors may transmit information that could not otherwise be had. This suggests that a trade-off exists between levels of trust in the coverage-reliability of official sources and (warranted) trust in rumor as a source of information. (shrink)

Vrijednosni obrat u epistemologiji iznjedrio je posebno utjecajnu poziciju – epistemologiju vrlina. Radi se o raširenom i utjecajnom epistemološkom projektu čiji je cilj postulirati intelektualne vrline spoznavatelja, a ne istinitost propozicije, kao središnje epistemičke vrijednosti. U prvom dijelu članka kratko ćemo izložiti o kakvom se vrijednosnom obratu radi te izložiti temeljne postavke epistemologije vrline, ukazujući na raznorodnost stavova epistemologa koji su se priklonili ovom pristupu, ali i na plodno širenje epistemoloških obzora. U drugom dijelu fokusirat ćemo se na vrline epistemičke (...) odgovornosti i epistemičke pravednosti kao osobito primjerene za vrednovanje socijalnih spoznajnih procesa kao što je, primjerice, svjedočanstvo i komunikacija/konverzacija općenito. U trećem dijelu ćemo pokazati kako specifična spoznajna aktivnost – komunikacijski akt u psihijatriji i psihoterapiji – može biti analizirana i vrednovana iz perspektive vrline epistemičke pravednosti na epistemički bolji i učinkovitiji način nego što je to moguće kroz tradicionalni epistemički pristup utemeljen na monizmu istine.

Como una respuesta a la problemática mencionada, Axel Gelfert, profesor e investigador asociado en el Departamento de Filosofı́a de la Universidad de Singapur, publicó en 2014 su A critical introduction to testimony, el cual ha logrado posicionarse como una lectura obligatoria para aquellos interesados en la epistemologı́a del testimonio. En su libro se dedica a recorrer de manera propedéutica cada uno de los tópicos actuales de la epistemologı́a del testimonio, ello sin dejar de lado la profundidad y exhaustividad requerida para (...) una exposición apropiada de la complejidad epistemológica del testimonio como objeto de estudio.

This paper explores early Australasian philosophy in some detail. Two approaches have dominated Western philosophy in Australia: idealism and materialism. Idealism was prevalent between the 1880s and the 1930s, but dissipated thereafter. Idealism in Australia often reflected Kantian themes, but it also reflected the revival of interest in Hegel through the work of ‘absolute idealists’ such as T. H. Green, F. H. Bradley, and Henry Jones. A number of the early New Zealand philosophers were also educated in the idealist tradition (...) and were influential in their communities, but produced relatively little. In Australia, materialism gained prominence through the work of John Anderson, who arrived in Australia in 1927, and continues to be influential. John Anderson had been a student of Henry Jones, who might therefore be said to have influenced both main strands of Australian philosophical thought. (shrink)

Drawing on work by philosophers CAJ Coady and David Coady on the epistemology of rumours, I develop a theory which exploits the distinction between rumouring and rumour-mongering for the purpose of explaining why we should treat rumours as a species of justified belief. -/- Whilst it is true that rumour-mongering, the act of passing on a rumour maliciously, presents a pathology of the normally reliable transmission of rumours, I will argue that rumours themselves have a generally reliable transmission process, that (...) of rumouring, and should be considered to be examples of warranted beliefs. -/- My argument will also touch on the association of rumours with another class of beliefs that are usually considered to be suspect, conspiracy theories. I will argue that whilst rumours are reliable (as a mechanism for the transmission of justified beliefs) the analysis of the transmission of conspiracy theories requires us to realise they are different to rumours in some important respects.
