Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

Drawing on work from Marina Sbisà’s “Ideology and the Persuasive Use of Presupposition,” Rae Langton has developed a powerful account of the subtle mechanisms through which hate speech and propaganda spread. However, this model has a serious limitation: it focuses too strongly on individual speech acts isolated from their wider context, rendering its applicability to a broader range of cases suspect. In this paper, I consider the limits of presupposition accommodation to clarify the audience’s role in helping hate speakers, and (...) claim the necessary mechanisms are much more active and social than Langton suggests, with effects not capturable in the analysis of isolated speech acts. I revisit Sbisà’s work on presupposition and develop an alternative model that (1) improves upon the Langtonian model for explaining the power of hate propaganda, and (2) is more in line with Sbisà’s original approach to ideology and the normative aspects of presupposition.

This chapter examines what protest is from the point of view of pragmatics, and how it relates to propaganda—specifically what Jason Stanley calls ‘positive propaganda.’ It analyzes the phrase “Black Lives Matter,” taking it to be a political speech act that offers a unique route to understanding of the pragmatics of protest. From this, it considers the moral-epistemological function of protest, and develops an account of the authority that protest, as a speech act, both calls upon and makes explicit. It (...) then argues that, rather than simply its effects, it is protest’s distinct pragmatic features—that is, its entitlement conditions, and the uptake it aim at—that best capture its important moral, political, and epistemic elements. It therefore rejects the idea that protests are paradigmatic examples of ‘positive propaganda,’ because the propaganda model cannot capture protests’ function of foregrounding the socially located moral authority of the protestor.

A lot of subordinating speech has moved online, which raises several questions for social philosophers of language. Can current accounts of oppressive speech adequately capture digital hate? How does the anonymity of online harassers contribute to the force of their speech? This paper examines online abuse and argues that standard accounts of licensing and accommodation are not up to the task of explaining the authority of online hate speech, as speaker authority often depends on the community in more ways than (...) these accounts suggests. Instead I argue that online abusive speech is best understood as collective subordinating speech acts, as their authority is drawn from an ad hoc collective. I argue that anonymity and shared language offer online abusers a path to a type of speaker authority that explains the harm their speech is capable of. I close by suggesting that similar considerations are in play for offline subordinating speech as well, and that attention to online abuse reveals features of subordinating speech across mediums that are under-emphasized in the existing literature.

This dissertation fits within the literature on subordinating speech and aims to demonstrate that how language subordinates is more complex than has been described by most philosophers. I argue that the harms that subordinating speech inflicts on its targets (chapter one), the type of authority that is exercised by subordinating speakers (chapters two and three), and the expansive variety of subordinating speech acts themselves (chapter three) are all under-developed subjects in need of further refinement—and, in some cases, large paradigm shifts. (...) I also examine cases that have yet to be adequately addressed by philosophers working on this topic, like the explosion of abusive speech online (chapter four) or the distinctive speech acts of protest groups (chapter five). I argue that by considering these alongside the ‘paradigm’ cases of subordinating speech that inform most models, we are better able to capture the lived realities of this phenomena, as described by members of groups targeted by such speech. I develop a novel account of speaker authority to explain the variety of pragmatic effects subordinating speech generates. Instead of seeing this authority as reducible to either a formal position or a merely local, linguistic phenomenon, I argue for a conception of speaker authority that is a richly contextual social fact, distributed unevenly among members of different social groups. I also develop an account of collective authority that explains how a group of speakers can join together to subordinate in a way that no individual speaker is capable of doing. This account, I argue, is better able to explain the social reality of subordinating speech than individualist models. Overall, I show how a more fine-grained account of subordinating speaker authority gives us a more accurate picture of the different subordinating speech acts available to different speakers, along with how these may harm their targets.
