I outline what I call the ‘deniability problem’, explain why it is problematic, and identify the range of utterances to which it applies (using religious discourse as an example). The problem is as follows: To assign content to many utterances audiences must rely on their contextual knowledge. This generates a lot of scope for error. Thus, speakers are able to make assertions and deny responsibility for the proposition asserted, claiming that the audience made a mistake. I outline the problem (a (...) limited version of which Fricker 2012 discusses), before explaining why it is problematic. Firstly it blocks testimonial knowledge according to assurance views. Secondly it prevents epistemic buck passing (the importance of which is emphasized by Goldberg 2006 and McMyler 2013). Finally, it removes a key disincentive to dishonesty. The recent literature on context sensitivity (particularly Cappelen and Lepore 2004) seems to entail that the problem applies to a very wide range of utterances. I consider a series of responses which fail to provide a solution, but which help us narrow down the scope of the problem. (shrink)

This paper provides an account of anonymous speech treated as anonymized speech. It is argued that anonymous speech acts are best defined by reference to intentional acts of blocking a speaker's identification as opposed to the various epistemic effects that imperfectly correlate with these actions. The account is used to examine two important subclasses of anonymized speech: speech using pseudonyms, and speech anonymized in a specifically communicative manner. Several pragmatic and ethical issues with anonymized speech are considered.

There's been a great deal of interest in epistemology regarding what it takes for a hearer to come to know on the basis of a speaker's say-so. That is, there's been much work on the epistemology of testimony. However, what about when hearers don't believe speakers when they should? In other words, what are we to make of when testimony goes wrong? A recent topic of interest in epistemology and feminist philosophy is how we sometimes fail to believe speakers due (...) to inappropriate prejudices – implicit or explicit. This is known as epistemic injustice. In this article, I discuss Miranda Fricker's groundbreaking work on epistemic injustice, as well as more recent developments that both offer critique and expansion on the nature and extent of epistemic injustice.

Various social epistemologists employ what seem to be rather distinct notions of group rationality. In this essay, I offer an account of group rationality that is able to unify the dominant notions present in the literature under a single framework. I argue that if we employ a teleological account of epistemic rationality, and then allow that there are many different epistemic goals that are worth pursuing for various groups and individuals, we can then see how those seemingly divergent understandings of (...) group rationality are all intimately related. I close by showing how the view has the additional benefit of allowing us to generate practical, normative suggestions for groups in the real world. (shrink)

According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This paper aims to fill this gap. It offers a precise characterisation of assertoric commitment, and shows how it can be applied to define assertion. On the proposed view, acquiring commitment is (...) not sufficient for asserting. To assert, commitment must be acquired by explicitly presenting a proposition as true. (shrink)

I can, given the right conditions, transmit my knowledge to you by telling you some information. If I know the time, and if all goes well, I can bring it about that you know it too. If conditions are right, all I have to do is assert to you what time it is. Paradigmatically, speakers use assertions to transmit what they know to their hearers. Clearly, assertion and testimony are tightly connected. The nature of this connection, however, is not so (...) clear. According to many accounts, assertion has an epistemic constitutive norm. This norm appears to be able to account for some important features of testimony: first, testimonial knowledge transmission, second, the reliability of testimony, and third, the epistemic rights exchanged in cases of testimony. In this paper, however, I argue against this apparent ability. The constitutive norm of assertion, I argue, plays no role in accounts of testimonial knowledge transmission, or of the epistemic rights that testimony confers. This is especially clear whe..

The COVID-19 pandemic has been accompanied by an “infodemic” of misinformation and conspiracy theory. This article points to three explanatory factors: the challenge of forming accurate beliefs when overwhelmed with information, an implausibly individualistic conception of epistemic virtue, and an adversarial information environment that suborns epistemic dependence. Normally we cope with the problems of informational excess by relying on other people, including sociotechnical systems that mediate testimony and evidence. But when we attempt to engage in epistemic “superheroics” - withholding trust (...) from others and trying to figure it all out for ourselves – these can malfunction in ways that make us vulnerable to forming irrational beliefs. Some epistemic systems are prone to coalescing audiences around false conspiracy theories. This analysis affords a new perspective on philosophical efforts to understand conspiracy theories and other epistemic projects prone to collective irrationality. (shrink)

The world is witnessing a rise in speech-enabled devices serving as epistemic informants to their users. Some philosophers take the view that because the utterances produced by such machines can be phenomenologically similar to an equivalent human speech, and they may deliver the same function in terms of delivering content to their audience, such machine utterances should be conceptualized as “assertions”. This paper argues against this view and highlights the theoretical and pragmatic challenges faced by such a conceptualization which seems (...) to be based on a “functionalist” account of assertion. Instead, the paper argues that the view that some such machine utterances can be “proxy assertions”, made on behalf of the designers and/or deployers of such machines is more tenable. Existing accounts of such a view, however, need further refinement, which is provided here. The paper then discusses implications of this view for design of such machines, particularly those enabled and equipped with machine learning capabilities. (shrink)

This paper reviews recent philosophical work on assertion, with a special focus on work exploring the theme of assertion's norm. It concludes with a brief section characterizing several open questions that might profitably be explored from this perspective.
