Speech acts are governed by a variety of illocutionary norms. Building on Sbisà’s (2019) work, this chapter attempts to develop a common framework to study them. Four families of illocutionary rules are identified: (i) Validity rules set conditions for (actual) performance; (ii) Cooperative rules set conditions for cooperative performance; (iii) Illocutionary goals set conditions for successful performance; (iv) Illocutionary obligations set conditions for compliance. Illocutionary rules are often taken to play a constitutive role: speech acts are said to be constituted (...) by the unique set of rules that regulates them. Against this view, it is argued that many illocutionary rules are instead best construed as rationally derivable expectations of cooperation. This alternative paradigm provides fertile ground to reconcile scholarly disagreement between speech act theorists, and yields a promising explanation of how illocutionary norms are learned and evolve through time.

Can fictions lie? According to a classic conception, works of fiction cannot contain lies, since their content is neither presented as true nor meant to deceive us. But this classic view can be challenged. Sometimes fictions appear to make claims about the actual world, and these claims can be designed to convey falsehoods, historical misconceptions, and pernicious stereotypes. Should we conclude that some fictional statements are lies? This article presents two views that support a positive answer, and two that support (...) a negative one. After examining various ways in which fictions can deceive, it concludes in favour of the view that fictional statements can mislead, but never lie. (shrink)

This book challenges the view that bad beliefs - beliefs that blatantly conflict with easily available evidence - can largely be explained by widespread irrationality, instead arguing that ordinary people are rational agents whose beliefs are the result of their rational response to the evidence they're presented with.

Abstract The typical explanation of an event or process which attracts the label ‘conspiracy theory’ is an explanation that conflicts with the account advanced by the relevant epistemic authorities. I argue that both for the layperson and for the intellectual, it is almost never rational to accept such a conspiracy theory. Knowledge is not merely shallowly social, in the manner recognized by social epistemology, it is also constitutively social: many kinds of knowledge only become accessible thanks to the agent's embedding (...) in an environment that includes other epistemic agents. Moreover, advances in knowledge typically require ongoing immersion in this social environment. But the intellectual who embraces a conspiracy theory risks cutting herself off from this environment, and therefore epistemically disabling herself. Embracing a conspiracy theory therefore places at risk the ability to engage in genuine enquiry, including the enquiry needed properly to evaluate the conspiracy theory. (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)

This paper analyses the communicative and epistemic value of retweeting (and more generally of reposting content on social media). Against a naïve view, it argues that retweets are not acts of endorsement, motivating this diagnosis with linguistic data. Retweeting is instead modelled as a peculiar form of quotation, in which the reported content is indicated rather than reproduced. A relevance-theoretic account of the communicative import of retweeting is then developed, to spell out the complex mechanisms by which retweets achieve their (...) communicative goals. The last section outlines the epistemic threats posed by the increasing prevalence of retweeting on social media, linking them to the low reputational, cognitive and practical costs linked to this emerging form of communication.

There is a fundamental disagreement about which norm regulates assertion. Proponents of factive accounts argue that only true propositions are assertable, whereas proponents of non-factive accounts insist that at least some false propositions are. Puzzlingly, both views are supported by equally plausible (but apparently incompatible) linguistic data. This paper delineates an alternative solution: to understand truth as the aim of assertion, and pair this view with a non-factive rule. The resulting account is able to explain all the relevant linguistic data, (...) and finds independent support from general considerations about the differences between rules and aims. (shrink)

Not every speech act can be a lie. A good definition of lying should be able to draw the right distinctions between speech acts that can be lies and speech acts that under no circumstances are lies. This paper shows that no extant account of lying is able to draw the required distinctions. It argues that a definition of lying based on the notion of ‘assertoric commitment’ can succeed where other accounts have failed. Assertoric commitment is analysed in terms of (...) two normative components: ‘accountability’ and ‘discursive responsibility’. The resulting definition of lying draws all the desired distinctions, providing an intensionally adequate analysis of the concept of lying. (shrink)

How can we capture the intuitive distinction between lying and misleading? According to a traditional view, the difference boils down to whether the speaker is saying (as opposed to implying) something that they believe to be false. This view is subject to known objections; to overcome them, an alternative view has emerged. For the alternative view, what matters is whether the speaker can consistently deny that they are committed to knowing the relevant proposition. We point out serious flaws for this (...) alternative view, and sketch a simpler alternative that incorporates key insights of the traditional view. (shrink)

In a recent article, Krauss (2017) raises some fundamental questions concerning (i) what the desiderata of a definition of lying are, and (ii) how definitions of lying can account for partial beliefs. This paper aims to provide an adequate answer to both questions. Regarding (i), it shows that there can be a tension between two desiderata for a definition of lying: 'descriptive accuracy' (meeting intuitions about our ordinary concept of lying), and 'moral import' (meeting intuitions about what is wrong with (...) lying), vindicating the primacy of the former desideratum. Regarding (ii), it shows that Krauss' proposed 'worse-off requirement' meets neither of these desiderata, whereas the 'comparative insincerity condition' (Marsili 2014) can meet both. The conclusion is that lies are assertions that the speaker takes to be more likely to be false than true, and their distinctive blameworthiness is a function of the extent to which they violate a sincerity norm.

McKenna’s critique (rather than criticisms) of idealized approaches to epistemology is an important contribution to the literature. In this brief discussion, I set out his main concerns about more idealized approaches, within and beyond social epistemology, before turning to some issues I think he neglects. I suggest that it’s important to pay attention to the prestige hierarchy in philosophy, and to how that hierarchy can serve ideological purposes. The greater prestige of more abstract approaches plays a role in determining what (...) issues and what voices we attend to. (shrink)

Groups, like individuals, can communicate. They can issue statements, make promises, give advice. Sometimes, in doing so, they lie and deceive. The goal of this paper is to offer a precise characterisation of what it means for a group to make an assertion and to lie. I begin by showing that Lackey’s influential account of group assertion is unable to distinguish assertions from other speech acts, explicit statements from implicatures, and lying from misleading. I propose an alternative view, according to (...) which a group asserts a proposition only if it explicitly presents that proposition as true, thereby committing to its truth. This proposal is then put to work to define group lying. While scholars typically assume that group lying requires (i) a deceptive intent and (ii) a belief in the falsity of the asserted proposition, I offer a definition that drops condition (i) and significantly broadens condition (ii). (shrink)

A new definition of lying is gaining traction, according to which you lie only if you say what you know to be false. Drawing inspiration from “New Evil Demon” scenarios, I present a battery of counterexamples against this “Knowledge Account” of lying. Along the way, I comment upon the methodology of conceptual analysis, the moral implications of the Knowledge Account, and its ties with knowledge-first epistemology.

This paper is divided into two parts. In the first part, I extend the traditional definition of lying to illocutionary acts executed by means of explicit performatives, focusing on promising. This is achieved in two steps. First, I discuss how the utterance of a sentence containing an explicit performative such as “I promise that Φ ” can count as an assertion of its content Φ . Second, I develop a general account of insincerity meant to explain under which conditions a (...) given illocutionary act can be insincere, and show how this applies to promises. I conclude that a promise to Φ is insincere (and consequently a lie) only if the speaker intends not to Φ , or believes that he will not Φ , or both. In the second part, I test the proposed definition of lying by promising against the intuitions of ordinary language speakers. The results show that, unlike alternative accounts, the proposed definition makes the correct predictions in the cases tested. Furthermore, these results challenge the following necessary conditions for telling a lie with content p: that you have to assert p directly; that you have to believe that p be false; that p must be false; that you must aim to deceive the addressee into believing that p.

Assertions are our standard communicative tool for sharing and acquiring information. Recent empirical studies seemingly provide converging evidence that assertions are subject to a factive norm: you are entitled to assert a proposition p only if p is true. All these studies, however, assume that we can treat participants' judgments about what an agent 'should say' as evidence of their intuitions about assertability. This paper argues that this assumption is incorrect, so that the conclusions drawn in these studies are unwarranted. (...) It shows that most people do not interpret statements about what an agent 'should say' as statements about assertability, but rather as statements about what is in the agent's interest to do. It identifies some effective measures to force the intended reading of statements about what an agent 'should say', and shows that when these measures are implemented, people's judgments consistently and overwhelmingly align with non-factive accounts of assertion.

In a recent book (_Lying and insincerity_, Oxford University Press, 2018), Andreas Stokke argues that one lies iff one says something one believes to be false, thereby proposing that it becomes common ground. This paper shows that Stokke’s proposal is unable to draw the right distinctions about insincere performative utterances. The objection also has repercussions on theories of assertion, because it poses a novel challenge to any attempt to define assertion as a proposal to update the common ground.

According to an influential hypothesis, the speech act of assertion is subject to a single 'constitutive' rule, that takes the form: "One must: assert that p only if p has C". Scholars working on assertion interpret the assumption that this rule is 'constitutive' in different ways. This disagreement, often unacknowledged, threatens the foundations of the philosophical debate on assertion. This paper reviews different interpretations of the claim that assertion is governed by a constitutive rule. It argues that once we understand (...) the full import of assuming that assertion is governed by a constitutive rule, it becomes clear that some fundamental assumptions of the current debate are mistaken, and others unwarranted.

Can fictions make genuine assertions about the actual world? Proponents of the ‘Assertion View’ answer the question affirmatively: they hold that authors can assert, by means of explicit statements that are part of the work of fiction, that something is actually the case in the real world. The ‘Nonassertion’ View firmly denies this possibility. In this paper, I defend a nuanced version of the Nonassertion View. I argue that even if fictions cannot assert, they can indirectly communicate that what is (...) recounted as fictional is actually true. I show that this view is supported by independent linguistic data, and that it is able to defuse the objections that are typically raised against the Nonassertion View. I conclude by showing that this position has some interesting implications for testimonial cognitivism about fiction. (shrink)

Is truth the rule or the aim of assertions? Philosophers disagree. After reviewing the available evidence, the hypothesis that truth is the aim of assertion is defended against recent attempts to prove that truth is rather a rule of assertion.

Defends and transforms naturalism and materialism to show how culture itself is formed by nature. Bryant endorses a pan-ecological theory of being, arguing that societies are ecosystems that can only be understood by considering nonhuman material agencies such as rivers and mountain ranges alongside signifying agencies such as discourses, narratives and ideologies.

In the philosophical debate on lying, there has generally been agreement that either the speaker believes that his statement is false, or he believes that his statement is true. This article challenges this assumption, and argues that lying is a scalar phenomenon that allows for a number of intermediate cases – the most obvious being cases of uncertainty. The first section shows that lying can involve beliefs about graded truth values (fuzzy lies) and graded beliefs (graded-belief lies). It puts forward (...) a new definition to deal with these scalar parameters, that requires that the speaker asserts what he believes more likely to be false than true. The second section shows that statements are scalar in the same way beliefs are, and accounts for a further element of scalarity, illocutionary force. (shrink)

In the philosophical literature on the definition of lying, the analysis is generally restricted to cases of flat-out belief. This chapter considers the complex phenomenon of lies involving partial beliefs – beliefs ranging from mere uncertainty to absolute certainty. The first section analyses lies uttered while holding a graded belief in the falsity of the assertion, and presents a revised insincerity condition, requiring that the liar believes the assertion to be more likely to be false than true. The second section (...) analyses assertions that express graded beliefs, exploring how mitigation and reinforcement can alter the insincerity conditions for lying. The last section considers the case of lies that attack certainty (knowledge-lies), understood as attempt to alter the hearer's graded beliefs. (shrink)

In a series of articles (Pagin, 2004, 2009), Peter Pagin has argued that assertion is not a social speech act, introducing a method (which we baptize ‘the P-test’) designed to refute any account that defines assertion in terms of its social effects. This paper contends that Pagin's method fails to rebut the thesis that assertion is social. We show that the P-test is both unreliable (because it overgenerates counterexamples) and counterproductive (because it ultimately provides evidence in favor of some social (...) accounts). Nonetheless, we contend that assertion is not fully social. We defend an intermediate view according to which assertion is only a partly social speech act: assertions both commit the speaker to a proposition (a social component) and present their propositional content as true (a non-social component). The upshot is that assertion is in some important respect social, although it cannot be defined solely in terms of its social effects. (shrink)

This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)

Arguably, a theory of assertion should be able to provide (i) a definition of assertion, and (ii) a set of conditions for an assertion to be appropriate. This paper reviews two strands of theories that have attempted to meet this challenge. Commitment-based accounts à la Peirce define assertion in terms of commitment to the truth of the proposition. Restriction-based accounts à la Williamson define assertion in terms of the conditions for its appropriate performance. After assessing the suitability of these projects (...) to meet the desiderata of a theory of assertion, I argue that a speech act theoretic account à la Searle is more suitable for this purpose: it integrates the core intuitions of both restriction-based and commitment-based accounts while avoiding their respective problems, and has the further advantage of determining how assertion fits into a more general theory of illocutionary acts.

Continental philosophy has entered a new period of ferment. The long deconstructionist era was followed with a period dominated by Deleuze, which has in turn evolved into a new situation still difficult to define. However, one common thread running through the new brand of continental positions is a renewed attention to materialist and realist options in philosophy. Among the leaders of the established generation, this new focus takes numerous forms. It might be hard to find many shared positions in the (...) writings of Badiou, DeLanda, Laruelle, Latour, Stengers, and Žižek, but what is missing from their positions is an obsession with the critique of written texts. All of them elaborate a positive ontology, despite the incompatibility of their results. Meanwhile, the new generation of continental thinkers is pushing these trends still further, as seen in currents ranging from transcendental materialism to the London-based speculative realism movement to new revivals of Derrida. As indicated by the title The Speculative Turn, the new currents of continental philosophy depart from the text-centered hermeneutic models of the past and engage in daring speculations about the nature of reality itself. This anthology assembles authors, of several generations and numerous nationalities, who will be at the centre of debate in continental philosophy for decades to come. (shrink)

From one end of his philosophical work to the other, Gilles Deleuze consistently described his position as a transcendental empiricism. But just what is transcendental about Deleuze’s transcendental empiricism? And how does his position fit with the traditional empiricism articulated by Hume? In Difference and Givenness , Levi Bryant addresses these long-neglected questions so critical to an understanding of Deleuze’s thinking. Through a close examination of Deleuze’s independent work--focusing especially on Difference and Repetition-- as well as his engagement with thinkers (...) such as Kant, Mai;mon, Bergson, and Simondon, Bryant sets out to unearth Deleuze’s transcendental empiricism and to show how it differs from transcendental idealism, absolute idealism, and traditional empiricism. What emerges from these efforts is a metaphysics that strives to articulate the conditions for real existence, capable of accounting for the individual itself without falling into conceptual or essentialist abstraction. In Bryant’s analysis, Deleuze’s metaphysics articulates an account of being as process or creative individuation based on difference, as well as a challenging critique--and explanation--of essentialist substance ontologies. A clear and powerful discussion of how Deleuze’s project relates to two of the most influential strains in the history of philosophy, this book will prove essential to anyone seeking to understand Deleuze’s thought and its specific contribution to metaphysics and epistemology.

The principle of epistemic closure is the claim that what is known to follow from knowledge is known to be true. This intuitively plausible idea is endorsed by a vast majority of knowledge theorists. There are significant problems, however, that have to be addressed if epistemic closure – closed knowledge – is endorsed. The present essay locates the problem for closed knowledge in the separation it imposes between knowledge and evidence. Although it might appear that all that stands between knowing (...) the truth of the premises of a valid inference and knowledge of its conclusion is inferring it from the premises, the evidence for each of the premises may jointly count against the conclusion. The intuitive view regarding inferred knowledge says one thing, the evidence says another. One epistemological framework that seems to have the resources to resolve this tension endorses the view that knowledge always requires conclusive evidence. A second framework resolves the tension by limiting the scope of the closure principle. Only inferences drawn directly from propositions contained in the scope of a single knowledge operator are considered closed. The aim of the present essay is to revive the unpopular third option, the idea that knowledge is open. The essay proceeds by arguing that in different ways the two former frameworks only succeed in relocating the problem, not in resolving it. The first framework, the infallibilist view, relocates the problem to a sharp separation between knowledge of the occurrences of events from knowledge of their chance of occurring, a separation leading to several significant additional problems. The fallibilist view, the second framework, in endorsing closure neglects to take into full account the ways in which evidence fails to be transitive. For instance, evidence can count in favor of a conjunction while counting against each of its conjuncts. This fact, which is argued for in the essay on probabilistic as well as non-probabilistic grounds, is used as the foundation of an argument against closed knowledge that can be used as a way to understand several of the most fundamental challenges of epistemology. Not only can an open knowledge view that is based on open evidence resolve all these problems in a simple and natural way, it can also respond to formidable challenges that significantly hinder other open knowledge views. There are good reasons, then, to view both knowledge and evidence as open. (shrink)

What can Dungeons & Dragons teach us about the being of beings? This article argues that Dungeons & Dragons introduces us to a world composed of objects or entities, where the being of objects is defined not by their qualities, but rather by their powers, capacities or affects. Drawing on the thought of Spinoza, Deleuze and Molnar, objects are seen to be defined by what they can do or their capacities to act, such that qualities are effects of these acts. (...) Dungeons & Dragons is particularly suited to showing us this insofar as it focuses on the action of entities. (shrink)

In this paper the analysis of the classical dynamics of a charged particle is carried out without considering that the electromagnetic field necessarily goes to zero at infinity. A quite general non-linear equation of motion is obtained for an extended charged particle valid for any distribution of charge in the particle and for an electromagnetic field satisfying any boundary conditions. Some common approximations are analyzed with detail to determine how the usual difficulties arise.

An alternative approach to analyze the nonrelativistic quantum dynamics of a rigid and extended charged particle taking into account the radiation reaction is discussed with detail. Interpretation of the field operators as annihilation and creation ones, theory of perturbations and renormalization are not used. The analysis is carried out in the Heisenberg picture with the electromagnetic field expanded in a complete orthogonal basis set of functions which allows the electromagnetic field to satisfy arbitrary boundary conditions. The corresponding coefficients are the (...) field operators which satisfy the usual commutation relations. A nonlinear equation of motion for the charged particle is obtained. A careful consideration of the quantum effects allows the derivation of a linear equation of motion which is free of both runaway solutions and preacceleration, even for a point charge. Also, the electromagnetic mass, which is defined as the coefficient of the acceleration operator, vanishes for a point particle. However, this does not mean that the results are free of ambiguities which are exhibited and discussed. (shrink)

Since Kant, philosophy has been obsessed with epistemological questions pertaining to the relationship between mind and world and human access to objects. In The Democracy of Objects Bryant proposes that we break with this tradition and once again initiate the project of ontology as first philosophy. Drawing on the object-oriented ontology of Graham Harman, as well as the thought Roy Bhaskar, Gilles Deleuze, Niklas Luhman, Aristotle, Jacques Lacan, Bruno Latour and the developmental systems theorists, Bryant develops a realist ontology that (...) he calls “onticology”. This ontology argues that being is composed entirely of objects, properties, and relations such that subjects themselves are a variant of objects. By way of systems theory and cybernetics, Bryant argues that objects are dynamic systems that relate to the world under conditions of operational closure. In this way, he integrates the most vital discoveries of the anti-realists within a realist ontology that does justice to both the material and cultural. Onticology proposes a flat ontology where objects of all sorts and at different scales equally exist without being reducible to other objects and where there are no transcendent entities such as eternal essences outside of dynamic interactions among objects. This work will be of great interest to Continental philosophers, ecologists, cultural theorists, media theorists, and those following recent developments in the thought of speculative realists.

His most important essays in these areas are assembled here, with an introduction setting (...) out their main themes and connections. As a whole the volume presents a coherent, elaborated position which will be of great interest to a range of philosophers, decision theorists, welfare and social choice theorists and cognitive scientists.

Most philosophers think that phenomenal consciousness underlies, or at any rate makes a large contribution, to moral considerability. This paper argues that many such accounts invoke question-begging arguments. Moreover, they’re unable to explain apparent differences in moral status across and within different species. In the light of these problems, I argue that we ought to take very seriously a view according to which moral considerability is grounded in functional properties. Phenomenal consciousness may be sufficient for having a moral value, but (...) it may not be necessary, and it may contribute relatively little to our overall considerability. (shrink)

Moral realism is often taken to have common sense and initial appearances on its side. Indeed, by some lights, common sense and initial appearances underlie all the central positive arguments for moral realism. We offer a kind of debunking argument, taking aim at realism’s common sense standing. Our argument differs from familiar debunking moves both in its empirical assumptions and in how it targets the realist position. We argue that if natural selection explains the objective phenomenology of moral deliberation and (...) judgement, then this undermines arguments from that phenomenology. This results in a simpler, and in some ways more direct, challenge to realism. It is also less vulnerable to the main objections that have been leveled against such arguments. If accepted, our conclusion should make a real difference to the dialectic in this area. It means that neither realism nor its denial is the default, to-be-refuted, position. (shrink)
