In the paper we argue that truth-relativism is potentially hostage to a problem of exhibiting witnesses of its own truth. The problem for the relativist stems from acceptance of a trumping principle according to which there is a dependency between ascriptions of truth of an utterance and ascriptions of truth to other ascriptions of truth of that utterance. We argue that such a dependency indeed holds in the case of future contingents and the case of epistemic modals and that, consequently, (...) the relativist about these domains cannot exhibit witnesses to his relativism. In the appendix we provide some results on the relation between trumping and multi-order relativism. (shrink)

§1 To many in or on the edges of the Academy, ”Relativism” is a word with overtones of sinister iconoclasm, representing a kind of intellectual and ethical free-for-all in which the traditional investigative virtues of clarity, rigour, objectivity, consistency and the unbiased pursuit of truth are dismissed as illusory and the great scientific constructions of the last two hundred years, together with our deepest moral convictions, rated merely as ‘our way of seeing’ the world, more elaborate and organised but otherwise (...) on all fours with the cosmology and customs of primitive tribes. In his short book, Paul Boghossian aims to address, and to expose as bankrupt, the idea that there is even a coherent, let alone defensible philosophical stance about truth and knowledge that can underwrite these ‘pluralist’, or ‘postmodernist’ tendencies. But since it is crucial to his project that his style of discussion make it available to non-specialists, much of the recent more technical, less emotional debate within analytical philosophy about relativism’s renaissance as a particular form of semantic theory is passed over unmentioned. Part of my aim in what follows is to illustrate how Boghossian's discussion connects quite straightforwardly with relativism in its contemporary analytical philosophical livery—what I have elsewhere called New Age relativism1— and how some of his critical arguments may be presented in that setting. My main contentions will be, first, that when relativism about epistemic justification, and about morals, are couched in the currently canonical sort of form, they still remain in range of artillery that Boghossian positions in chapter 6 of his book; second, that there is evasive action that they can..

A dynamic semantics for epistemically modalized sentences is an attractive alternative to the orthodox view that our best theory of meaning ascribes to such sentences truth-conditions relative to what is known. This essay demonstrates that a dynamic theory about might and must offers elegant explanations of a range of puzzling observations about epistemic modals. The first part of the story offers a unifying treatment of disputes about epistemic modality and disputes about matters of fact while at the same time avoiding (...) the complexities of alternative theories. The second part of the story extends the basic framework to cover some complicated data about retraction and the interaction between epistemic modality and tense. A comparison between the suggestion made in this essay and current versions of the orthodoxy is provided. (shrink)

Epistemic modals are a prominent topic in the literature on natural language semantics, with wide-ranging implications for issues in philosophy of language and philosophical logic. Considerations about the role that epistemic "might" and "must" play in discourse and reasoning have led to the development of several important alternatives to classical possible worlds semantics for natural language modal expressions. This is an opinionated overview of what I take to be some of the most exciting issues and developments in the field.

The purpose of this paper is to define the sentence-tokened—a product of utterance distinct from the act of utterance—and highlight the role that it can play in communication. In particular, the author will suggest that this entity is plausibly at the root of John MacFarlane’s motivating intuitions for the view that truth is assessment-sensitive. Here the author argues that the truth-value intuitions that MacFarlane uses to motivate his view can be accommodated within the Kaplanian semantic framework, once we acknowledge the (...) sentence-tokened and the role it can play.

The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we call (...) reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

Relativism is often motivated in terms of certain types of disagreement. In this paper, we survey the philosophical debates over two such types: faultless disagreement in the case of gustatory conflict, and fundamental disagreement in the case of epistemic conflict. Each of the two discussions makes use of a implicit conception of judgement: brute judgement in the case of faultless disagreement, and rule-governed judgement in the case of fundamental disagreement. We show that the prevalent accounts work with unreasonably high levels (...) of idealization. We defend two claims. First, philosophical discussions of disagreement need to be de-idealized. Second, once a less idealized account of disagreement is available, both our conception of judgement and our understanding of relativism need to be revised. Our example is a case study in the Sociology of Scientific Knowledge: Steven Shapin and Simon Schaffer’s classic Leviathan and the Air-Pump. This case study gives a less idealized account of disagreement that conceptualizes judgements as situated. We argue that this conception can and should be applied to cases of gustatory and epistemic disagreement. The payoff will be a reformulation of relativism in terms of rationally resolvable yet contingent disagreements. (shrink)

At the center of the debate between contextualist versus relativist semantics for epistemic modal claims is an empirical question about when competent subjects judge epistemic modal disagreement to be present. John MacFarlane’s relativist claims that we judge there to be epistemic modal disagreement across the widest range of cases. We wish to dispute the robustness of his data with the results of two studies. Our primary conclusion is that the actual disagreement data is not consistent with relativist predictions, and so, (...) that the primary motivation for relativism disappears. Our study differs from a related study by Knobe and Yalcin :1–21, 2014) in that we focus directly on the question of genuine disagreement, as opposed to a question about truth or the appropriateness of retraction. Some of our findings agree with theirs about relativism. We uncover new lessons along the way, including that there are widespread situation effects of epistemic modal discourse; idiosyncratic features of the vignettes significantly influencing judgments about epistemic modal disagreement. We reflect with mixed feelings on the prospects for contextualism to accommodate our findings. (shrink)

The argument from faultless disagreement employed by the relativist purports to show that contextualism falls short of explaining cases of faultless disagreement. The demonstration is intended to give credence to the relativist semantics of epistemic modality expressions. In this paper we present some cases showing that even though cases of faultless disagreement do reveal some intrinsic features of epistemic modality claims, they do not support the relativist semantics. The sophistication of faultless disagreement goes beyond what the relativist semantics can cope (...) with. We also advance an epistemologically oriented proposal to account for faultless disagreement. (shrink)

In this paper I offer some critical comments to MacFarlane's recent book "Assessment Sensitivity". I focus primarily on MacFarlane's understanding of the normative aspects of enquiry—in particular I take issue with the phenomena of retraction and disagreement as preclusion of joint accuracy. I argue that both notions are problematic and that—at least in the case of basic taste—they are not needed in order to account for our intuitions.

Relativism and contextualism are the most popular accounts of faultless disagreement, but Crispin Wright once argued for an account I call divergentism. According to divergentism, parties who possess all relevant information and use the same standards of assessment in the same context of utterance can disagree about the same proposition without either party being in epistemic fault, yet only one of them is right. This view is an alternative to relativism, indexical contextualism, and nonindexical contextualism, and has advantages over those (...) views. Wright eventually abandoned this view in favor of relativism for reasons related to a conciliationist view of disagreement between epistemic peers. I argue that he gave up on divergentism too soon.

I investigate the implication of the truth-relativist’s alleged ‘ faultless disagreements’ for issues in the epistemology of disagreement. A conclusion I draw is that the type of disagreement the truth-relativist claims to preserve fails in principle to be epistemically significant in the way we should expect disagreements to be in social-epistemic practice. In particular, the fact of faultless disagreement fails to ever play the epistemically significant role of making doxastic revision rationally required for either party in a disagreement. That the (...) truth-relativists’ disagreements over centred content fail to play this epistemically significant role that disagreements characteristically play in social epistemology should leave us sceptical that disagreement is what the truth-relativist has actually preserved.

Invariantism about ‘might’ says that ‘might’ semantically expresses the same modal property in every context. This paper presents and defends a version of invariantism. According to it, ‘might’ semantically expresses the same weak modal property in every context. However, speakers who utter sentences containing ‘might’ typically assert propositions concerning stronger types of modality, including epistemic modality. This theory can explain the phenomena that motivate contextualist theories of epistemic uses of ‘might’, and can be defended from objections of the sort that (...) relativists mount against contextualist theories.

Relativists about knowledge ascriptions think that whether a particular use of a knowledge-ascribing sentence, e.g., “Keith knows that the bank is open” is true depends on the epistemic standards at play in the assessor’s context—viz., the context in which the knowledge ascription is being as- sessed for truth or falsity. Given that the very same knowledge-ascription can be assessed for truth or falsity from indefinitely many perspectives, relativism has a striking consequence. When I ascribe knowledge to someone (e.g., when I (...) say that, at a particular time, “Keith knows that the bank is open”), what I’ve said does not get a truth-value absolutely, but only relatively. If this semantic thesis about the word “knows” and its cognates is true, what implications would this have for epistemology, the philosophical theory of knowledge? e present aim will be to engage with this mostly unexplored question, and then to consider how the epistemological conclusions drawn might bear on the plausibility of a relativist semantics for “knows”.

Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. Defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. Detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. Debates about relativism permeate the whole spectrum of philosophical sub-disciplines. From ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy (...) has felt the need to respond to this heady and seemingly subversive idea. Discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called “analytic and continental” camps in philosophy. And yet, despite a long history of debate going back to Plato and an increasingly large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. This entry attempts to provide a broad account of the many ways in which “relativism” has been defined, explained, defended and criticized. (shrink)

Recently, a number of theorists (MacFarlane (2003, 2011), Egan et al. (2005), Egan (2007), Stephenson (2007a,b)) have argued that an adequate semantics and pragmatics for epistemic modals calls for some technical notion of relativist truth and/or relativist content. Much of this work has relied on an empirical thesis about speaker judgments, namely that competent speakers tend to judge a present-tense bare epistemic possibility claim true only if the prejacent is compatible with their information. Relativists have in particular appealed to judgments (...) elicited in so-called eavesdropping and retraction cases to support this empirical thesis. But opposing theorists have denied the judgments, and at present there is no consensus in the literature about how the speaker judgments in fact pattern. Consequently there is little agreement on what exactly a semantics and pragmatics for epistemic modals should predict about the pattern of judgments in these cases. Further theorizing requires greater clarity on the data to be explained. To clarify the data, we subjected eavesdropping and retraction cases to experimental evaluation. Our data provide evidence against the claim that competent speakers tend to judge a present-tense bare epistemic possibility claim true only if the prejacent is compatible with their information. Theories designed to predict this result are accordingly undermined. (shrink)

Concerning the versions of the Tenseless Theory of Time, the Old Btheory has two: the Date-analysis version and the Token-reflexive version, while the New B-theory has three: the Date-analysis, the Token-reflexive and the Sentence-type versions. Each of these five versions of the B-theory has received serious attacks from the A-theorists, some of whom even claim that the tenseless theory “though still widely held, is a theory in retreat” (Craig 1996), and that “if Quentin Smith (1993) delivered the mortal blow to (...) the New B-Theory of Language then Laurie Paul (1997) has written its obituary” (Craig 1999). In this paper, by making more precise some key notions involved in the formulation of a tenseless theory – in particular, two notions of truth conditions, two notions of meaning and two notions of translation are distinguished – I have come up with a single B-thesis for the B-theory. When charitably interpreted, the two versions of the old theory and the three versions of the new theory can all be regarded as special ways of presenting the same B-thesis, and the various A-attacks raised against these versions can then be resolved in a systematic way.

Assessment relativism, as developed by John MacFarlane, is the view that the truth of our claims involving a variety of English expressions—‘tasty’, ‘knows’, ‘tomorrow’, ‘might’, and ‘ought’—is relative not only to aspects of the context of their production but also to aspects of the context in which they are assessed. Assessment relativism is thus a form of truth relativism which is offered as a new way of understanding perspectival thought and talk. In this article, I present the main theses of (...) assessment relativism, focusing in particular on highlighting the points of commonality and contrast with other forms of truth relativism. I then offer some critical remarks concerning the motivation of assessment relativism in relation to matters of taste. (shrink)
