This paper has two aims: it develops and defends a fully-fledged account of the epistemic normativity of conjecture it goes sharply against orthodoxy, in arguing that conjecture is epistemically more demanding than assertion. According to the view defended here, one’s conjecture that p is permissible only if one knows that one has warrant, but not sufficient warrant to believe that p. I argue for my account on three independent grounds: the Bach and Harnish account of the nature of communicative speech (...) acts, the plausible normative relation between assertion and other constatives, and the normativity of belief in conjunction with constatives’ epistemic function.

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and expertise, has been misconstrued at times. (...) (2) Questions of expertise and methodology could be separated more clearly. (3) The study of expertise may be important in its own right; however, there may be good reasons to give priority to methodological concerns. (4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project. (shrink)

During the past several decades, many epistemologists have argued for and contributed to a paradigm shift according to which knowledge is central to assertion, action, and interaction. This general position stands in sharp contrast to several recently developed accounts regarding specific epistemic contexts. These specific accounts resist applying traditional epistemic norms, including strong knowledge norms, to real-world situations of interest. In particular, I consider recent arguments about the epistemic standards for scientific pronouncements, expert testimony in a political context, and interactive (...) reasoning. I argue, firstly, that knowledge does have a crucial role to play in each case, contrary to appearances. Clarifying the role of knowledge fills gaps in our understanding left open by the existing accounts. Secondly, I show that combining the insights from the knowledge-centric approach and from the more specific accounts provides a new perspective on the open problem of developing an account of knowledge-based decisions. Specifically, I argue that the biggest open problem regarding knowledge-based decisions is not how we respond to uncertainty, but rather how we assess the relevance of our many disparate pieces of knowledge, choosing which to integrate, and how. A strong case emerges for a procedural solution to this part of the problem of how to make knowledge-based decisions. (shrink)

Most philosophers have largely downplayed any relevance of multiple meanings of the folk concept of truth in the empirical domain. However, confusions about what truth is have surged in political and everyday discourse. In order to resolve these confusions, we argue that we need a more accurate picture of how the term ‘true’ is in fact used. Our experimental studies reveal that the use of ‘true’ shows substantial variance within the empirical domain, indicating that ‘true’ is ambiguous between a correspondence (...) and a coherence reading. We then explore the consequences of these results for the project of re-engineering truth. (shrink)

According to the widely endorsed Knowledge Account of Assertion, the epistemic requirements on assertion are captured by the Knowledge Norm of Assertion, which requires speakers only to assert what they know. This paper proposes that in addition to the Knowledge Norm there is also an Epistemic Propositional Certainty Norm of Assertion, which enjoins speakers only to assert p if they believe that p on the basis of evidence which makes p an epistemic propositional certainty. The paper explains how this propositional (...) certainty norm accounts for a range of data related to the practice of assertion and defends the norm against general objections to certainty norms of assertion put forward by Duncan Pritchard, John Turri, and Timothy Williamson, by drawing on linguistic theories about epistemic modals and gradable predicate semantics. Together these considerations show that the prospects of a certainty account of assertion are much more promising than is usually assumed. (shrink)

If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced: 1. If causal determinism is true, all events are necessitated2. If all events are necessitated, then there are no powers3. Free will consists in the exercise of an agent’s powersTherefore, if causal determinism is true, there is no free will; which is to say (...) that free will is incompatible with determinism, so compatibilism is false.

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.

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.

When agents violate norms, they are typically judged to be more of a cause of resulting outcomes. In this paper, we suggest that norm violations also affect the causality attributed to other agents, a phenomenon we refer to as "causal superseding." We propose and test a counterfactual reasoning model of this phenomenon in four experiments. Experiments 1 and 2 provide an initial demonstration of the causal superseding effect and distinguish it from previously studied effects. Experiment 3 shows that this causal (...) superseding effect is dependent on a particular event structure, following a prediction of our counterfactual model. Experiment 4 demonstrates that causal superseding can occur with violations of non-moral norms. We propose a model of the superseding effect based on the idea of counterfactual sufficiency. (shrink)

Assertions are speech acts by means of which we express beliefs. As such they are at the heart of our linguistic and social practices. Recent research has focused extensively on the question whether the speech act of assertion is governed by norms, and if so, under what conditions it is acceptable to make an assertion. Standard theories propose, for instance, that one should only assert that p if one knows that p (the knowledge account), or that one should only assert (...) that p if p is true (the truth account). In a series of four experiments, this question is addressed empirically. Contrary to previous findings, knowledge turns out to be a poor predictor of assertability, and the norm of assertion is not factive either. The studies here presented provide empirical evidence in favour of the view that a speaker is warranted to assert that p only if her belief that p is justified. (shrink)

The topic of epistemic normativity has come to the fore of recent work in epistemology, and so naturally, theories of knowledge, truth and justification have been increasingly held accountable to preserving normative epistemological platitudes. Central to discussions of epistemic normativity are questions about epistemic agency and epistemic value. Here, our aim is to take up some of these issues as they come to bear on the rather unconventional brand of epistemology that was defended by Richard Rorty. Our purpose is to (...) explore whether Rorty’s epistemology—or perhaps his replacement for epistemology—can preserve these normative platitudes about epistemic agency, responsibility, achievement, and the value of knowledge. Our conclusion is a negative one: that Rorty’s commitments leave him firmly at odds with some of the most plausible assumptions about epistemic agency and epistemic value. (shrink)

Several studies have found a robust effect of truth on epistemic evaluation of belief, decision, action and assertion. Thus, truth has a significant effect on normative participant evaluations. Some theorists take this truth effect to motivate factive epistemic norms of belief, action, assertion etc. In contrast, I argue that the truth effect is best understood as an epistemic instance of the familiar and ubiquitous phenomenon of outcome bias. I support this diagnosis from three interrelating perspectives: (1) by epistemological theorizing, (2) (...) by considerations from cognitive psychology and (3) by methodological reflections on the relationship between folk epistemology and epistemological theorizing.

We report a series of experiments examining whether people ascribe knowledge for true beliefs based on probabilistic evidence. Participants were less likely to ascribe knowledge for beliefs based on probabilistic evidence than for beliefs based on perceptual evidence or testimony providing causal information. Denial of knowledge for beliefs based on probabilistic evidence did not arise because participants viewed such beliefs as unjustified, nor because such beliefs leave open the possibility of error. These findings rule out traditional philosophical accounts for why (...) probabilistic evidence does not produce knowledge. The experiments instead suggest that people deny knowledge because they distrust drawing conclusions about an individual based on reasoning about the population to which it belongs, a tendency previously identified by “judgment and decision making” researchers. Consistent with this, participants were more willing to ascribe knowledge for beliefs based on probabilistic evidence that is specific to a particular case. 2016 APA, all rights reserved). (shrink)

In what sense, if any, are philosophers experts in their domain of research and what could philosophical expertise be? The above questions are particularly pressing given recent methodological disputes in philosophy. The so-called expertise defense recently proposed as a reply to experimental philosophers postulates that philosophers are experts qua having improved intuitions. However, this model of philosophical expertise has been challenged by studies suggesting that philosophers’ intuitions are no less prone to biases and distortions than intuitions of non-philosophers. Should we (...) then give up on the idea that philosophers possess some sort of expertise? In this paper, I argue that instead of focusing on intuitions, we may understand the relevant results of philosophical practice more broadly and investigate the other kind of expertise they would require. My proposal is inspired by a prominent approach to investigating expert performance from psychology and suggests where and how to look for expertise in the results characteristic of philosophical practice. In developing this model, I discuss the following three candidates for such results: arguments, theories, and distinctions. Whether philosophers could be shown to be expert intuiters or not, there are interesting domains where we could look for philosophical expertise, beyond intuitions. (shrink)

This chapter reviews empirical research on the rules governing assertion and retraction, with a focus on the normative role of truth. It examines whether truth is required for an assertion to be considered permissible, and whether there is an expectation that speakers retract statements that turn out to be false. Contrary to factive norms (such as the influential “knowledge norm”), empirical data suggests that there is no expectation that speakers only make true assertions. Additionally, contrary to truth-relativist accounts, there is (...) no requirement for speakers to retract statements that are false at the context of assessment. We conclude by suggesting that truth still plays a crucial role in the evaluation of assertions: as a standard for evaluating their success, rather than permissibility. (shrink)

Contextualism is the view that the extension of perspectival claims (involving e.g. predicates of personal taste or epistemic modals) depends on the context of utterance. Relativism is the view that the extension of perspectival claims depends on the context of assessment. Both views make concrete, empirically testable predictions about how such claims are used by ordinary English language speakers. This chapter surveys some of the recent empirical literature on the topic and presents four new experiments (total N=724). Consistent with contextualism (...) and inconsistent with relativism, the results suggest that the extension of perspectival claims depends on the context of utterance, not the context of assessment.

The past eighteen years witnessed the rapid development of experimental philosophy of language. Adopting a bibliometric approach, this study examines the research trends and status quo of this burgeoning field based on a corpus of 237 publications retrieved from PhilPapers. It is observed that experimental philosophy of language has undergone three stages, the initiation stage, the development stage, and the extension stage, across which there is a clear upward trend in the annual number of publications. Michael Devitt, Edouard Machery, John (...) Turri, Nat Hansen, et al., are found to be the most productive philosophers, testifying their leading positions in this field. Journals, instead of books, are the major homes of works in this area. The analysis also yields a list of influential works, including the seminal work “Semantics, Cross-cultural Style” and other significant publications on the semantics of various types of expressions. Relatedly, the major research themes are found to include not only intuitions about the reference of proper names, but also a wide array of philosophically and linguistically interesting issues like the meaning of color adjectives, epistemic modals, and predicates of personal taste, the norms of assertions and the essence of lies, etc. These findings showcase that experimental philosophy of language has broadened the research territory and offered deep insights into central issues of philosophy of language that are beyond the reach of the conventional armchair methodology.

Asserting is the act of claiming that something is the case—for instance, that oranges are citruses, or that there is a traffic congestion on Brooklyn Bridge (at some time). We make assertions to share information, coordinate our actions, defend arguments, and communicate our beliefs and desires. Because of its central role in communication, assertion has been investigated in several disciplines. Linguists, philosophers of language, and logicians rely heavily on the notion of assertion in theorizing about meaning, truth and inference. -/- (...) The nature of assertion and its relation to other speech acts and linguistic phenomena (implicatures, presuppositions, etc.) have been subject to much controversy. This entry will situate assertion within speech act theory and pragmatics more generally, and then go on to present the current main accounts of assertion. (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)

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.

It is often thought that judgments about what we ought to do are limited by judgments about what we can do, or that “ought implies can.” We conducted eight experiments to test the link between a range of moral requirements and abilities in ordinary moral evaluations. Moral obligations were repeatedly attributed in tandem with inability, regardless of the type (Experiments 1–3), temporal duration (Experiment 5), or scope (Experiment 6) of inability. This pattern was consistently observed using a variety of moral (...) vocabulary to probe moral judgments and was insensitive to different levels of seriousness for the consequences of inaction (Experiment 4). Judgments about moral obligation were no different for individuals who can or cannot perform physical actions, and these judgments differed from evaluations of a non-moral obligation (Experiment 7). Together these results demonstrate that commonsense morality rejects the “ought implies can” principle for moral requirements, and that judgments about moral obligation are made independently of considerations about ability. By contrast, judgments of blame were highly sensitive to considerations about ability (Experiment 8), which suggests that commonsense morality might accept a “blame implies can” principle. (shrink)
