L’agence d’expertise indépendante INDEX, constituée d’architectes, d’artistes et de chercheurs, enquête sur les violences d’État en France et depuis la France. Dans cet entretien, iels expliquent comment iels réinvestissent politiquement la notion d’expertise dans les enquêtes policières, racontent leurs liens avec le collectif Forensic Architecture, explicitent ce qu’iels entendent par « vérité » dans les enquêtes en sources ouvertes et ce qu’iels mettent en place pour permettre une plus grande dissémination des outils de l’OSINT.

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.

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.

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)

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)

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. -/- .

Contextualism concerning vagueness (hereafter ‘CV’) is a popular response to the puzzle of vagueness.[1] The goal in this paper is to uncover in what ways vagueness may be a particular species of context-sensitivity. The most promising form of CV turns out to be a version of socalled ‘Non-Indexical Contextualism’.[2] In §2, we sketch a generic form of CV (hereafter ‘GCV’). In §3, we distinguish between Truth CV and Content CV. A non-indexical form of CV is a form of (...) Truth CV, while an indexical form of CV is a form of Content CV. In §4, we argue that the theory of vagueness given in Fara (2000) is crucially incomplete but is best seen as a non-indexical form of CV. In §5, we set forth four kinds of error-theory to which CV might be committed. It turns out that Non-Indexical CV is committed to a weaker, and more plausible, error-theory than Indexical CV. In §6, we address a challenge posed by Keefe (2007) to the effect that CV entails that any speech report of what has been said by a particular vague utterance, where the context of utterance and the reporting context are relevantly different, will almost always be inaccurate. While this challenge is prima facie effective against Indexical CV it proves to be less effective against Non-Indexical CV. In §7, we look at two tests for context-sensitivity and assess whether they can be employed against CV. These tests, if cogent, reveal that the only workable form of CV is Non-Indexical CV. (shrink)

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)

Truth conditional semantics is the project of ‘determining a way of assigning truth conditions to sentences based on A) the extension of their constituents and B) their syntactic mode of combination’. This research program has been subject to objections that take the form of underdetermination arguments, an influential instance of which is presented by Travis: … consider the words ‘The leaf is green,’ speaking of a given leaf, and its condition at a given time, used so as to mean what (...) they do mean in English. How many distinct things might be said in words with all that true of them? Many.… Suppose a Japanese maple leaf, turned brown, was painted green for a decoration. In sorting leaves by colour, one might truly call this one green. In describing leaves to help identify their species, it might, for all the paint, be false to call it that. (shrink)

Some time ago, John Perry argued that the content of an indexical belief, that is, a belief expressible with a sentence containing an indexical or demonstrative, cannot be a proposition. I consider several of his arguments for this view, and show that they can be extended to show that belief expressible with other non-indexical expressions such as natural kind terms and proper names presents the very same problem for the traditional picture. I then suggest that if (...) class='Hi'>indexical belief has any special status, this is not because it has a special kind of content, but rather because action is impossible if agents do not have indexical belief.

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)

In his presidential address on “Symbols, Signs, and Signals,” given before the Association for Symbolic Logic, December 28, 1938, Professor C. J. Ducasse made and important distinction between what he there called the indicative and the quiddative symbol. He remarked in passing that he thought it possible to show that: 1) “The same entity may function both as indicative and as quiddative symbol: or one part of a complex symbol may be quiddative and another indicative”; and 2) “the difference between (...) the two roles is irreducible: the indicative is not a species of the quiddative nor vice versa.” An indicative symbol is defined as “one of which the distinctive property is to orient our attention to some place in an order system …”; and a quiddative symbol as “one of which the distinctive property is to make us conceive a certain kind of thing—a certain ‘what'—no matter where in any order system it may or may not be existing.”.

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.

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

The day to day experiences of answering machine messages, written notes, postcard messages, etc. and our intuitions regarding these seem to contradict the traditional assumptions in the semantics of indexicals. The primary analytical scope of the article is to undertake an analysis of Allyson Mount’s convergence of perspectives-based account of indexical reference and see whether it is able to successfully meet the challenges faced by Stefano Predelli’s intended context of interpretation approach towards the semantics of indexicals, thereby providing a (...) viable solution to the Answering Machine Paradox.
