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.

One can have no prior credence whatsoever (not even zero) in a temporally indexical claim. This fact saves the principle of conditionalization from potential counterexample and undermines the Elga and Arntzenius/Dorr arguments for the thirder position and Lewis' argument for the halfer position on the Sleeping Beauty Problem, thereby supporting the double-halfer position. -/- .

The new evil demon problem amounts to a difficult challenge for the externalist about epistemic justification. Many solutions to the problem have been proffered in the almost 40 years since its first appearance in the literature. Among the more promising responses is indexical reliabilism, a combination of two versions of actual world reliabilism where “actual” denotes either the world of utterance or a rigidly determined actual world. This paper does three things. First, it attempts to clarify indexical reliabilism (...) and how it purports to solve the new evil demon problem. Second, it attempts to mitigate some of the prominent criticism that has been leveled against the theory. Third, it poses an explanatory challenge for the theory which remains even after all of the premises supporting indexical reliabilism are accepted. The conclusion is that indexical reliabilism is not tenable until a linguistic mechanism for the use of “actually reliable” has been offered that explains how the theory avoids collapsing into a two-concepts response to the new evil demon problem.

David Lewis, Stewart Cohen, and Keith DeRose have proposed that sentences of the form S knows P are indexical, and therefore differ in truth value from one context to another.1 On their indexical contextualism, the truth value of S knows P is determined by whether S meets the epistemic standards of the speakers context. I will not be concerned with relational forms of contextualism, according to which the truth value of S knows P is determined by the standards (...) of the subject Ss context, regardless of the standards applying to the speaker making the knowledge claim. Relational contextualism is a form of normative relativism. Indexical contextualism is a semantic theory. When the subject is the speaker, as when S is the first person pronoun I, the two forms of contextualism coincide. But otherwise, they diverge. I critically examine the principal arguments for indexicalism, detail linguistic evidence against it, and suggest a pragmatic alternative. (shrink)

During vocal production, pulses natures in the voice and are related to the shape and of air generated by the rapid movement of the vocal length of the vocal tract.

E. J. Lowe sets out in a recent paper1 to refute McTaggart's proof of the unreality of time, by exposing an ‘indexical fallacy’ in his disproof of the existence of tensed (i. e., A-series) facts.2 Lowe then develops an original account of what makes time the dimension of change, based on his own account of tensed facts. But in our opinion he fails on both counts: (1) he fails to refute McTaggart's perfectly sound disproof of tensed facts, which shows (...) that time can be real only if (Lowe and McTaggart not withstanding) it needs no tensed facts, and (2) he fails to explain the temporal character of change, since his account of it has an exact spatial analogue. In what follows we argue these two points in turn. (shrink)

This book investigates the subjective and objective representations of the world, developing analogies between secondary qualities and indexical thoughts and arguing that subjective representations are ineliminable. Throughout, McGinn brings together historical and contemporary discussions to illuminate old problems in a novel way.

A context-shifting example involves a putatively non-ambiguous, non-elliptical, non-indexical declarative sentence, some distinct utterances of which differ in truth value despite sameness of place, time, surrounding objects, and other physical factors. Charles Travis has spawned a large literature by arguing that such examples undermine compositional truth-conditional semantics. After explaining how prior responses to Travis’s examples fail in the metaphysical details, the present essay develops a new approach that treats a wide range of subject terms as disguised indexicals sensitive to (...) mereological structure.

Many domains, notably the one involving predicates of personal taste, present the phenomenon of apparent faultless disagreement. Contextualism is a characteristically moderate implementation of the relativistic attempt to endorse such appearances. According to an often-voiced objection, although it straightforwardly accounts for the faultlessness, contextualism fails to respect “facts about disagreement.” With many other recent contributors to the debate, I contend that the notion of disagreement—“genuine,” “real,” “substantive,” “robust” disagreement—is indeed very flexible, and in particular can be constituted by contrasting attitudes. (...) As such, contextualism is clearly straightforwardly compatible with facts about the existence of disagreement. There is, however, a genuine prima facie worry for contextualism involving facts about the expression of disagreement in ordinary conversations. Elaborating on a suggestion by Lewis :113–138, 1989), I argue that the presupposition of commonality approach in López de Sa shows that there are versions of contextualism that are in good standing vis-à-vis such facts about the expression of disagreement.

This paper explores how organizational members use documents to share their knowledge within and across work settings. I suggest that organizational studies of distributed knowledge sharing and information systems would greatly benefit from the linguistic analysis of communicative practices. Specifically, the paper highlights the notion of indexical centering as formulated by the linguistic anthropologist William Hanks and demonstrates its analytical power in studying documenting as a communicative practice. Drawing on a 15-month, multi-sited ethnographic study in several pediatric healthcare settings, (...) the paper focuses on how two doctors compose and use two medical histories found in two distinct medical information systems. The analysis suggests that the doctors use documents to index the temporal, spatial, and participatory dimensions of their knowledge sharing. They do so by indexing, on the one hand, the participants, times and places for their communicative practices and, on the other hand, the participants, times and places of their general care practices. The indexical analysis allows us to perceive documents, as more than mere vessels for knowledge transfer among organizational members, but as an integrated part of how people structure their work practices and situate their knowledge sharing in complex distributed organizational settings.

On the basis of an experimental investigation of the construals of present under past in child French, we argue that French children, just like Japanese adult speakers, but unlike French adult speakers, allow pure simultaneous construals of present under past, where the present denotes an interval that lies completely in the past, be it in relative or complement clauses. We conclude that French children have two presents: an indexical present and a zero present (just like Japanese adults, cf. Ogihara (...) 1999, 2008), suggesting that French children have both the Japanese and the French setting for the Sequence of Tense parameter since they allow simultaneous construals of both present and past under past. This multiple grammar approach to tense interpretation in child French extends to child Japanese in so far as Japanese children have been argued to allow simultaneous readings of past under past, although this reading is unavailable in the target grammar (Matsuo & Hollebrandse 1999).

Against the traditional theory of indexicals, I suggest that some utterances of sentences containing occurrences of indexical expressions must be evaluated with respect to a context distinct from the context of utterance. This proposal yields an intuitively correct treatment of a variety of linguistic phenomena. I discuss the interpretation of recorded messages, certain peculiar examples involving 'here', 'now', and 'I', the generic uses of indexicals, and some problems related to discourse about fiction. I also consider the logical consequences of (...) my view, and I argue that certain examples which are commonly taken as logically valid are not recognized as logical truths in my system. (shrink)

This article demonstrates how Peirce’s core definition of Index extends even to Objects which do not co-occur in space and time with their referent. Although the arguments are philosophical in nature, they are supported by developmental and empirical findings. The case of absent Objects as constituting Objects of indexical use is the primary focus; and rationale is offered from Peirce’s early and later work to bolster this claim. The analysis proffers the bold assertion that Index, especially in its Degenerate (...) use without an Interpretant, qualifies as the most primary sign vehicle, and that Index to absent Objects determines whether indexical use is Degenerate or Genuine.

No word in English is shorter than the word I.' And yet no word is more important in philosophy. When Descartes said I think therefore I am' he produced something that was both about himself and a universal formula. The word I' is called an indexical' because its meaning always depends on who says it. Other examples of indexicals are you,' here,' this' and now.' John Perry discusses how these kinds of words work, and why they express important philosophical (...) thoughts. He shows that indexicals pose a challenge to traditional assumptions about language and thought. Over the years a number of these papers, now included in this book, have sparked lively debates and have been influential in philosophy, linguistics and other areas of cognitive science. With seven new papers, including the previously unpublished What Are Indexicals?,' the present volume expands on an earlier version of this book published in the early nineties. Also included are the well-known papers Frege on Demonstratives,' Cognitive Significance and New Theories of Reference,' Evading the Slingshot,' The Prince and the Phone booth', Fodor on Psychological Explanations', and related papers on situation semantics, direct reference, and the structure of belief. This book also includes afterwords written by the author that discuss responses to his work by Gareth Evans, Robert Stalnaker, Barbara Partee, Howard Wettstein and others. (shrink)

The indexicality of film and sound recordings remains an unresolved problem in contemporary documentary theory. The prevailing conceptualisation of the documentary assigns it the status of a sober discourse, a framing in which history is modelled as absent cause and the unqualified distinction between fiction and non-fiction is considered sacrosanct. The denotative literalism characteristic of indexical media, however, confounds this conceptualisation, which in turn encourages the devaluing of documentary aesthetics; the documentary is not a medium of art, it is (...) said, but of argument. In this article, I examine how philosopher Jacques Rancière offers an alternative account of the documentary grounded on aesthetics rather than sobriety. I show how, in rethinking the absent cause model of history as well as the relationship between fiction and nonfiction, Rancière's aesthetic approach resolves the conceptual problem posed by indexicality and brings clarity to the value and function of indexical media with respect to the documentary.

John Perry argued that the clearest case of an indexical that relies only on the narrow context is 'I,' whose designation depends on the agent and nothing else. In this presentation, I give some examples which show that this view, while essentially correct, may have problems in some rare divergent cases.

Abstract: Proponents of the this-universe objection to fine-tuning arguments for a multiverse claim that while the multiverse hypothesis raises the probability that some universe is fine-tuned for life, it fails to raise the probability that this one is. Because that is so, they further argue, those who take the fine-tuning of this universe as evidence for the multiverse hypothesis are guilty of a probabilistic fallacy. I argue that a proper evaluation of the this-universe objection requires the development of a general, (...) formal framework for reasoning probabilistically with evidence statements expressed using indexical terms (such as the statement This universe is fine-tuned). I proceed to develop such a framework and then to apply it to the this-universe objection. While my primary aim is to defend the this-universe objection from recent rebuttals, a secondary aim is to exhibit the utility of the framework itself, which has the potential for wider application.

In this essay I will defend a novel version of the indexical view on proper names. According to this version, proper names have a relatively sparse truth-conditional meaning that is represented by their rigid content and indexical character, but a relatively rich use-conditional meaning, which I call the (contextual) constraint of a proper name. Firstly, I will provide a brief outline of my favoured indexical view on names in contrast to other indexical views proposed in the (...) relevant literature. Secondly, two general motivations for an indexical view on names will be introduced and defended. Thirdly, I will criticize the two most popular versions of the indexical view on names: formal variable accounts and salience-based formal constant accounts. In the fourth and final section, I will develop my own use-conditional indexical view on names in three different steps by confronting an initial version of this view with three different challenges.

ABSTRACT This paper demonstrates that the presuppositions triggered by the 1st and 2nd persons behave differently in important ways from those triggered by the 3rd person and the genders. While the 1st and 2nd persons trigger indexical presuppositions, the 3rd person and the genders do not. I show that the presuppositions triggered by the 1st and 2nd persons are not susceptible to presupposition failure of the kind familiar from ordinary presuppositions. Such failures occur for the 3rd person and the (...) genders. Moreover, the presuppositions triggered by the 1st and 2nd persons do not exhibit the projection behavior of ordinary presuppositions. The 3rd person and the genders do. I sketch a semantics in which the relevant difference is between presuppositions that impose constraints on functions from contexts to intensions and presuppositions that impose constraints on intensions.

The ways of thinking of things associated with a few indexical expressions—e.g. ‘I’, ‘now’, ‘that’—have a special role in the causation of action. They have a role not had by, for example, the guise associated with the ‘Superman’, or the guise associated with any other proper name. So, at least, an orthodox view about action—often associated with the phrase ‘essential indexical’—has it. Recently, this view has come under scrutiny. An increasing number of philosophers think it is a myth. (...) In this paper, I do two things. First, I argue that the orthodox view really is an insight, not a myth. Second, I offer an explanation of why it is that the insight holds. (shrink)

I argue that a recent variation on the Sleeping Beauty case due to Titelbaum [2012a] puts significant pressure on Lewis's theory of doxastic content—the theory of content that Titelbaum and others presuppose. In particular, that theory cannot make sense of the rational constraints on credences imposed by the Principal Principle, as ordinarily understood. I then argue more generally that any theory on which contents of credences are sets of centered worlds cannot adequately represent all of the rational constraints on credences.
