ABSTRACT What, if anything, should we do when someone says they don’t believe in anthropogenic climate change? Or that they worry that a COVID-19 vaccine might be dangerous? We argue that in general, we face an epistemic duty to object to such assertions, qua instances of science denial and science sceptical discourse, respectively. Our argument builds on recent discussions in social epistemology, specifically surrounding the idea that we ought to speak up against (epistemically) problematic assertions so as to fulfil an (...) important epistemic obligation – namely, preventing epistemic harms in others. We show that both science denial (SD) and vaccine hesitant (VH) discourses are harmful in a distinctively epistemic sense, and as such generate an especially strong duty to voice our disagreement. As we also argue, this obligation is nonetheless defeasible: depending on the situational features of those involved, voicing an objection to VH discourse may actually end up doing more harm than good. We conclude by tracing what seems like a promising path towards restoring well-placed public trust in scientific testifiers. Doing so is key in order to guarantee equitable access to warranted beliefs about important subject matters, such as the safety of vaccines, to all segments of society. (shrink)

Conversation, dialogue, reasonable disagreement, and the acquisition of knowledge through the words of others, all of this has always been at the center of philosophers’ concerns since the emergence of philosophy in Ancient Greece. It is also important to recognize that in contemporary philosophy, marked by the linguistic turn, there is a wealth of intellectual production on ethical, psycho-linguistic, logical-linguistic, and pragmatic aspects of the conversation. Despite all this, this is the first collection of texts dedicated exclusively to the strictly (...) epistemic aspects of this phenomenon which is so decisive for the very constitution of our humanity. This book brings together the contributions of fifteen leading philosophers on some of the most relevant issues of what we could call the Epistemology of Conversation. (shrink)

In this paper I argue that social networking sites (SNSs) are emotion technologies that promote a highly charged emotional environment where intrinsic emotion regulation is significantly weakened, and people's emotions are more strongly modulated by other people and by the technology itself. I show that these features of social media promote a simplistic emotional outlook which is an obstacle to the development and maintenance of virtue. In addition, I focus on the mechanisms that promote group-based anger and thus give rise (...) to affective polarisation. In the final section, after a discussion of the positive value of some forms of anger, I argue that SNSs should not be designed to prohibit or suppress anger, but that its encouragement should also be avoided. I conclude with a suggestion about how this might be achieved. (shrink)

According to the Assurance Theory of testimony, in telling an audience something, a speaker offers their assurance that what is told is true, which is something like their guarantee, or promise, of truth. However, speakers also tell lies and say things they do not have the authority to back up. So why does understanding tellings to be a form of assurance explain how tellings can provide a reason for belief? This paper argues that reasons come once it is recognised that (...) tellings are trusted. And the logic by means of which trust gives reason to believe is quite general; it applies equally to belief that is based on evidence rather than assurance. Outlining this logic requires the introduction of the idea of epistemic presumptions, whose truth plays the role of ensuring a connection between believer, justification and truth. (shrink)
