John MacFarlane explores how we might make sense of the idea that truth is relative. He provides new, satisfying accounts of parts of our thought and talk that have resisted traditional methods of analysis, including what we mean when we talk about what is tasty, what we know, what will happen, what might be the case, and what we ought to do.

Philosophers of language and linguists tend to think of the interpreter as an essentially non-creative participant in the communicative process. There’s no room, in traditional theories, for the view that correctness of interpretation depends in some essential way on the interpreter. As a result, there’s no room for the possibility that while P is the correct interpretation of an utterance, u, for one interpreter, P* is the correct interpretation of that utterance for another interpreter. Recently, a number of theorists have, (...) for separate reasons, argued in favour of a radically different view of communication – a view in which the interpreter and her context play what should be thought of as a content-creating role. According to such views, natural languages contain what I’ll call interpretation sensitive terms: terms the correct interpretation of which varies across interpreters (or, more generally, contexts of interpretation).3 An interpretation sensitive sentence can have one content relative to one interpreter and another content relative to another interpreter. This paper is a development and (partial) defence of the view that interpretation sensitivity is ubiquitous in natural language. I call the view that there are interpretation sensitive terms content relativism. Before starting the discussion of content relativism, it is worth pointing out that recent attempts to develop semantically motivated versions of truth relativism should be seen as part of this trend of giving the interpreter a more active role.

I set out and defend a view on indicative conditionals that I call “indexical relativism ”. The core of the view is that which proposition is expressed by an utterance of a conditional is a function of the speaker’s context and the assessor’s context. This implies a kind of relativism, namely that a single utterance may be correctly assessed as true by one assessor and false by another.

The particular behavior exhibited by sentences featuring predicates of personal taste such as “tasty” may drive us to claim that their truth depends on the context of assessment, as MacFarlane does. MacFarlane considers two ways in which the truth of a sentence can depend on the context of assessment. On the one hand, we can say that the sentence expresses a proposition whose truth-value depends on the context of assessment. This is MacFarlane’s position, which he calls “truth relativism” and, following (...) Weatherson, I rebrand as “nonindexical relativism”. On the other hand, we can say that what proposition a sentence expresses depends on the context of assessment. MacFarlane calls this position “content relativism” and rejects it on the grounds that it leads to implausible readings of certain sentences and is unable to account for the speaker’s authority over the content of her assertions. In this paper, I too argue against content relativism, which, again following Weatherson, I rebrand as “indexical relativism”. However, my arguments against the theory are different from MacFarlane’s, which I prove unsound. In particular, I show that any version of indexical relativism will be unable to account for at least one of the phenomena that have been standardly used to motivate nonindexical relativism—faultless disagreement and retraction—in most of the ways in which it has been proposed to understand them.

Though the divide between reason-based and causal-explanatory approaches in psychiatry and psychopathology is old and deeply rooted, current trends involving multi-factorial explanatory models and evidence-based approaches to interpersonal psychotherapy, show that it has already been implicitly bridged. These trends require a philosophical reconsideration of how reasons can be causes. This paper contributes to that trajectory by arguing that Donald Davidson’s classic paradigm of 1963 is still a valid option.

It is commonly held that retraction data, if they exist, show that assessment relativism is preferable to non-indexical contextualism. I argue that this is not the case. Whether retraction data have the suggested probative force depends on substantive questions about the proper treatment of tense and location. One’s preferred account in these domains should determine whether one accepts assessment relativism or non-indexical contextualism.

Most meanings we express belong to large families of variant meanings, among which it would be implausible to suppose that some are much more apt for being expressed than others. This abundance of candidate meanings creates pressure to think that the proposition attributing any particular meaning to an expression is modally plastic: its truth depends very sensitively on the exact microphysical state of the world. However, such plasticity seems to threaten ordinary counterfactuals whose consequents contain speech reports, since it is (...) hard to see how we could reasonably be confident in a counterfactual whose consequent can be true only if a certain very finely tuned microphysical configuration obtains. This essay develops the foregoing puzzle and explores several possible solutions. (shrink)

Some propositional attitude verbs require that the complement contain some “subjective predicate”. In terms of the theory proposed by Lasersohn, these verbs would seem to identify the “judge” of the embedded proposition with the matrix subject, and there have been suggestions in this direction. I show that it is possible to analyze these verbs as setting the judge and doing nothing more; then according to whether a judge index or a judge argument is assumed, unless the complement contains a subjective (...) predicate, the whole matrix is redundant or there is a type conflict. I further show that certain clear facts argue for assuming a judge argument which can be filled by a contextually salient entity–or by the subject of a subjective attitude verb. (shrink)

Contemporary interpretations of Zhuangzi’s 莊子 philosophy as adumbrating a relativist position are legion. However, what is the scope and nature of the relativism that can be gleaned from a comprehensive analysis of relevant passages in the Zhuangzi? In this essay, I shall explain Zhuangzi’s alleged relativist position as motivated from a primary concern about disagreement. He in effect claims that since any disputant can foresee her assertion to be refuted by an opponent, the recourse to a higher tribunal in adjudicating (...) the debate is futile. The consequence of an apparent lack of justification for assertion is, in my opinion, what needs elucidation. For example, is “truth relativism” an apt label for the nature of assertion in a debate without the verdict of a judge? Or, is it more appropriate to shun the concept of truth altogether in our explanation? I deem the contemporary explanation of Zhuangzi’s relativism either trivializes disputation or fails to account for the difference between a claim’s being right and being acceptable. Hence, I shall argue that without the intrusion of a judge as an arbiter of truth, the kind of disputation Zhuangzi practices promulgates faultless disagreement, which does not appeal to the correctness of any perspective in a comparative or absolute sense. In this understanding, Zhuangzi’s advice of harmonizing with both right and wrong is indeed a viable alternative to relativism and dogmatism, both of which do not properly take heed of the point of disagreeing in a disputation.

An introduction to relativism about truth.

Contextualists and relativists about predicates of personal taste, epistemic modals, and so on (“CR-expressions”) agree that the interpretation of these expressions depends, in some sense, on context. Relativists claim that the sort of context-sensitivity exhibited by CR-expressions is importantly different from that exhibited by paradigm context-sensitive expressions. This bifurcation is often motivated by the claim that the two classes of expressions behave differently in patterns of agreement and disagreement. I provide cases illustrating that the same sorts of discourse phenomena that (...) have been thought problematic for contextualists can arise with paradigm context-sensitive expressions. These cases motivate a more unified treatment of paradigm context-sensitive expressions and the expressions that have figured in recent contextualism/relativism debates. (shrink)

In recent discussions on contextualism and relativism, some have suggested that audience-sensitivity motivates a content relativist version of radical relativism, according to which a sentence as said at a context can have different contents with respect to the different perspectives from where it is assessed. The first aim of this note is to illustrate how this is not so. According to Egan himself, the phenomenon motivates at least refinement of the characteristic moderate contention that features of a single context determine (...) the appropriate truth-value of the sentence. The second aim of this note is to explore how this may not be so. (shrink)

This chapter develops an account of the meaning and use of various types of legal claims, and uses this account to inform debates about the nature and normativity of law. The account draws on a general framework for implementing a contextualist theory, called 'Discourse Contextualism' (Silk 2016). The aim of Discourse Contextualism is to derive the apparent normativity of claims of law from a particular contextualist interpretation of a standard semantics for modals, along with general principles of interpretation and conversation. (...) Though the semantics is descriptivist, it avoids Dworkin’s influential criticism of so-called “semantic theories of law,” and elucidates the nature of “theoretical disagreements” about the criteria of legal validity. The account sheds light on the social, interpersonal function of normative uses of language in legal discourse. It also gives precise expression to Hart’s and Raz’s intuitive distinctions among types of legal claims (internal/external, committed/detached), while giving them a uniform type of analysis. The proposed semantics and pragmatics of legal claims provides a fruitful framework for further theorizing about the nature and metaphysics of law, the relation between law and morality, and the apparent practical character of legal language and judgment. Discourse Contextualism provides a solid linguistic basis for a broader account of legal discourse and practice. (shrink)

This thesis comprises three main chapters—each comprising one relatively standalone paper. The unifying theme is fragmentalism about truth, which is the view that the predicate “true” either expresses distinct concepts or expresses distinct properties. -/- In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic (...) and semantics that shows how they can answer central conceptual and logical challenges for their view. -/- In Chapter 2, I motivate and develop a modal account of propositions on the basis of an iterative conception of propositions, where the modality is logico-mathematical. The modal account of propositions takes the conception to motivate an inherently potential hierarchy of propositions. I show that the account helps provide satisfying solutions to the intensional paradoxes of Russell-Myhill, Kaplan, and Prior. -/- In Chapter 3, I propose that “true” is polysemous. I suggest that “true” is initially polysemous between correspondence truth and disquotational truth, and further polysemous between the meanings corresponding to the subconcepts of the concept truth generated by the indefinite extensibility of that concept. I show that the proposal provides satisfying solutions to the semantic paradoxes. (shrink)

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)

Content- relativism is a semantic theory that states that the content of an uttered sentence can vary according to some feature of an assessment context. This paper has two objectives. The first is to determine which features a motivational case for content- relativism would display – what would a good case for content- relativism look like? The second is to consider cases that appear to have the required features and evaluate their prospects as motivational cases. I identify two varieties of (...) motivational case for content- relativism : content interpretation and content enhancement. I conclude that only content enhancement cases are likely to motivate content- relativism. (shrink)

Contextualist theories of truth appeal to context to solve the liar paradox: different stages of reasoning occur in different contexts, and so the contradiction is dispelled. The word ‘true’ is relativized by the contextualists to contexts of use. This paper shows that contextualist approaches to the liar are committed to a form of semantic relativism: that the truth value of some sentences depends on the context of assessment, as well as the context of use. In particular, it is shown how (...) Simmons’s and Glanzberg’s contextualist approaches entail relativism. In both cases, the liar sentence gets different semantic evaluations as uttered in a fixed context of use but assessed from different contexts. Shift in context of use alone cannot provide the full explanation of the liar. These contextualist approaches, as originally presented, were thus mischaracterised and they should be re-evaluated according to their full implications. (shrink)

This paper motivates and describes a non-alethic approach to faultless disagreement involving predicates of personal taste. In section 1 I describe problems faced by Sundell's indexicalist approach, and MacFarlane's relativist approach. In section 2 I develop an alternative, non-alethic, approach. The non-alethic approach is broadly expressivist in that it endorses both the negative semantic thesis that simple sentences containing PPTs do not semantically encode complete propositions and the positive pragmatic thesis that such sentences are used to express evaluative mental states. (...) Finally, in section 3 I explain how the non-alethic approach explains faultless disagreement. (shrink)

El relativismo acerca de las atribuciones de conocimiento de John MarFarlane pretende ser una teoría que explica la corrección de las intuiciones centrales que tenemos acerca de ellas. Sin embargo, el relativismo es incompatible con la corrección de algunas intuiciones que tenemos con respecto a casos de Stanley, a conjunciones de estos casos y a casos en los que la situación práctica del evaluador es menos apremiante que la del sujeto o la del emisor de la atribución. Esto, no obstante, (...) no señala un límite a las posibilidades del relativismo, sino que insta a dar versiones más sofisticadas del mismo. MarFarlane's relativism about knowledge attributions aspires to be a theory that explains why the central intuitions about them are correct. Nevertheless, relativism is incompatible with the accuracy of some intuitions about Stanley's cases, with conjunctions of them and with intuitions about cases in which there is less at stake from the assessor than what is at stake from the subject or the attributor. Nevertheless, this doesn't establish a limit to the possibilities of relativism, but calls for an improvement of it. (shrink)

In this paper I put forward and substantiate a possible defensive move on behalf of the relativist about predicates of personal taste that can be used to block a recent contextualist argument raised against the view: the ‘argument from binding’ proposed in Schaffer (). The move consists in adopting Recanati's “variadic functions” apparatus and applying it to predicates of personal taste like ‘tasty’ and experiencer phrases like ‘for John’. I substantiate the account in a basic relativistic framework and reply to (...) several objections to the variadic-functions approach in general and to its application to the expressions at hand.
