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)

It is a widely shared intuition that there is a close connection between knowledge-how and intentional action. In this paper, I explore one aspect of this connection: the normative connection between intending to do something and knowing how to do it. I argue for a norm connecting knowledge-how and intending in a way that parallels the knowledge norms of assertion, belief, and practical reasoning, which I call the knowledge-how norm of Intention. I argue that this norm can appeal to support (...) from arguments which parallel those for other epistemic norms, that it can deal with a number of prima facie problem cases, and that alternative conditions in a norm on intention are implausible.

In this paper I consider the prospects for an epistemic norm which relates knowledge-how to showing in a way that parallels the knowledge norm of assertion. In the first part of the paper I show that this epistemic norm can be motivated by conversational evidence, and that it fits in with a plausible picture of the function of knowledge. In the second part of the paper I present a dilemma for this norm. If we understand showing in a broad sense (...) as a general kind of skill teaching, then the norm faces counterexamples of teachers who know how to teach, but not to do. On the other hand, it we understand showing more narrowly as involving only teaching by doing the relevant activity, then the data which initially supported the norm can be explained away by more general connections between knowledge-how and intentional action.

In this thesis, I propose and defend a theory according to which committing oneself to knowing the proposition expressed counts as an assertion of that proposition. A consequence of this view is the knowledge account of assertion, according to which one asserts that p correctly only if one knows that p. In support of this approach, I offer a strategy of identifying an assertion’s “normative consequences”, types of act that normally take place as a result of one’s making an assertion (...) incorrectly. I outline two such phenomena: retraction and disavowal of knowledge. In continuation, I put the theory to test and critically examine four sets of objections against it, arguing that it can convincingly defuse them. Finally, I discuss two related issues: I maintain that by performing “aesthetic assertions” one also normally performs a non-assertoric speech act of recommendation, and argue for the possibility of “non-linguistic assertions”, whose content is expressed by gestures in appropriate contexts.

Epistemologists have proposed various norms of assertion to explain when a speaker is in an epistemic position to assert a proposition. In this article I propose a distinct necessary condition on assertibility: that a speaker should assert only what she sensitively believes, where a subject's belief is sensitive just in case the subject would not hold it if it were false. I argue that the Sensitivity Rule underwrites simple explanations for three key features of assertibility that pose explanatory challenges to (...) other prominent proposals: the fact that assertibility is open under known entailment, the general impropriety of assertions that a lottery ticket has lost made purely on the basis of the speaker's knowledge of the odds, and the fact that assertibility varies widely with features of the conversational context. I close by considering three distinct roles the Sensitivity Rule might play in the overall theory of assertibility. (shrink)

ABSTRACTI describe two ways of thinking about what constitutes a knowledgeable assertion – the ‘orthodox view’ and the ‘isomorphic view’. I argue that we should discard the orthodox view and replace it with the isomorphic view. The latter is more natural and has greater theoretical utility than the former.

There has been much recent interest in questions about epistemic norms of assertion. Is there a norm specific to assertion? Is it constitutive of the speech act? Is there a unique norm of this sort? What is its content? These are important questions, so it's understandable that they have received the attention which they have. By contrast, little attention—little separate attention, at least—has been given to parallel questions about telling: Which norm or norms govern telling, etc.? A natural explanation for (...) this disparity in interest is that it's felt generally to be obvious that there can be no significant distinction between the two types of norms, and hence no need to consider them separately. This paper challenges that general feeling. The first part argues that it's not obvious that the same norms govern assertion and telling. The second part argues that far from being obvious, this idea is mistaken: there are significant differences between the two types of norms. (shrink)

Lackey’s (2007) class of “selfless assertions” is controversial in at least two respects: it allows propositions that express Moorean absurdity to be asserted warrantedly, and it challenges the orthodox view that the speaker’s belief is a necessary condition for warranted assertibility. With regard to the former point, I critically examine Lackey’s broadly Gricean treatment of Moorean absurdity and McKinnon’s (2015) epistemic approach. With regard to the latter point, I defend the received view by supporting the knowledge account, on which knowledge (...) is the necessary condition for warranted assertion. After examining two defenses of KA, by Montminy and Turri, I propose two alternative approaches. Although I remain neutral between them, I develop in more detail the view which classifies “selfless assertions” as “presentations”, a type of assertives distinct from genuine assertions. This account is motivated further by allowing for the expansion of the normative approach to other assertives, a feature we may be interested in, in the light of a recent wave of normative accounts of speech acts.
