Incorporating techniques from book history into traditional intellectual history, this article traces the effective origin of indexing to the early printed editions of two lexicographical works, Lorenzo Valla's Elegantie and Niccolò Perotti's Cornu copiae, and then follows its development through the editions of the Roman poet Virgil published between 1500 and 1800. Indexing practices turn out to be tied to how books were read, with a new way of consuming books, which is labeled "transverse reading," emerging during this period.

Indexicals are linguistic expressions whose reference shifts from context to context: some paradigm examples are ‘I’, ‘here’, ‘now’, ‘today’,‘he’, ‘she’, and ‘that’. Two speakers who utter a single sentence that contains an indexical may say different things. For instance, Fred and Wilma say different things when they utter the sentence ‘I am female’. Many philosophers (following David Kaplan 1989a) hold that indexicals have two sorts of meaning. The first sort of meaning is often called ‘character’ or ‘linguistic meaning’; the second (...) sort is often called ‘content’. Using this terminology, we can say that the word ‘I’ has a single character (or linguistic meaning), but has different contents in different contexts. (shrink)

Reichenbachian approaches to indexicality contend that indexicals are "token-reflexives": semantic rules associated with any given indexical-type determine the truth-conditional import of properly produced tokens of that type relative to certain relational properties of those tokens. Such a view may be understood as sharing the main tenets of Kaplan's well-known theory regarding content, or truth-conditions, but differs from it regarding the nature of the linguistic meaning of indexicals and also regarding the bearers of truth-conditional import and truth-conditions. Kaplan has criticized (...) these approaches on different counts, the most damaging of which is that they make impossible a "logic of demonstratives". The reason for this is that the token-reflexive approach entails that not two tokens of the same sentential type including indexicals are guaranteed to have the same truth-conditions. In this paper I rebut this and other criticisms of the Reichenbachian approach. Additionally, I point out that Kaplan's original theory of "true demonstratives" is empirically inadequate, and claim that any modification capable of accurately handling the linguistic data would have similar problems to those attributed to the Reichenbachian approach. This is intended to show that the difficulties, no matter how real, are not caused by idiosincracies of the "token-reflexive" view, but by deep facts about indexicality. (shrink)

The subject of this book is the first person in thought and language. The main question concerns what we mean when we say 'J'. Related to it are questions about what kinds of self-consciousness and self-knowledge are needed in order for us to have the capacity to talk about ourselves. The emphasis is on theories of meaning and reference for 'J', but a fair amount of space is devoted to 'I' -thoughts and the role of the concept of the self (...) in cognition. The purpose is to give a picture of how we think and talk about ourselves in a wide range of circumstances. The topic has been discussed in numerous articles during the last decades, but rarely in the form of a monograph. I felt the need for a book of this kind while working on my dissertation. The manuscript is the result of many years of reflection on the self and indexicals. Some of the theories that I advance have developed as a result of my teaching an undergraduate course in the philosophy of language the last couple of years. (shrink)

We discuss a recent attempt by Chris Daly and Simon Langford to do away with mathematical explanations of physical phenomena. Daly and Langford suggest that mathematics merely indexes parts of the physical world, and on this understanding of the role of mathematics in science, there is no need to countenance mathematical explanation of physical facts. We argue that their strategy is at best a sketch and only looks plausible in simple cases. We also draw attention to how frequently Daly and (...) Langford find themselves in conflict with mathematical and scientific practice. (shrink)

Cappelen and Dever present a forceful challenge to the standard view that perspective, and in particular the perspective of the first person, is a philosophically deep aspect of the world. Their goal is not to show that we need to explain indexical and other perspectival phenomena in different ways, but to show that the entire topic is an illusion.

In this paper I argue against one variety of contextualism about aesthetic predicates such as “beautiful.” Contextualist analyses of these and other predicates have been subject to several challenges surrounding disagreement. Focusing on one kind of contextualism— individualized indexical contextualism —I unpack these various challenges and consider the responses available to the contextualist. The three responses I consider are as follows: giving an alternative analysis of the concept of disagreement ; claiming that speakers suffer from semantic blindness; and claiming that (...) attributions of beauty carry presuppositions of commonality. I will argue that none of the available strategies gives a response which both satisfactorily explains all of the disagreement -data and is plausible independent of significant evidence in favor of contextualism. I conclude that individualized indexical contextualism about the aesthetic is untenable, although this does not rule out alternative contextualist approaches to the aesthetic. (shrink)

Semantic Indexicality shows how a simple syntax can be combined with a propositional language at the level of logical analysis. It is the adoption of such a base language which has not been attempted before, and it is this which constitutes the originality of the book. Cresswell's simple and direct style makes this book accessible to a wider audience than the somewhat specialized subject matter might initially suggest.

The article presents two concepts of indexicality. The first, more standard and narrow, identifies indexicality with systematic (meaning controlled) context-sensitivity. The second, broader (derived from the work of Jerzy Pelc), conceives indexicality in terms of the potential variability of the general semiotic characteristics expressions (with respect to the context of use). The text introduces the concept of a pragmatic matrix that serves for a schematic representation of contextual variation. I also recapitulate briefly the views of Jerzy Pelc (...) on the meaning (manner of use) and use of expressions, and briefly indicate its relationship approaches with contemporary debates around contextualism and status of non-sentential speech acts. Finally, the relationship between the broader notion of indexicality and the directival theory of meaning is analyzed. (shrink)

Epistemic contextualism—the view that the content of the predicate ‘know’ can change with the context of utterance—has fallen into considerable disrepute recently. Many theorists have raised doubts as to whether ‘know’ is context-sensitive, typically basing their arguments on data suggesting that ‘know’ behaves semantically and syntactically in a way quite different from recognised indexicals such as ‘I’ and ‘here’ or ‘flat’ and ‘empty’. This paper takes a closer look at three pertinent objections of this kind, viz. at what I call (...) the Error-Theory Objection, the Gradability Objection and the Clarification-Technique Objection. The paper concludes that none of these objections can provide decisive evidence against contextualism. (shrink)

Various data from communication that does not occur face-to-face are taken to be problematic for Kaplan’s account of indexical expressions, as is the case with the so-called answering machine paradox. One fix, developed by Sidelle (1991) and Briciu (2018), is the remote utterance view: recording artifacts are means by which speakers perform utterances at a distance, just as by means of other artifacts agents performs other types of actions at a distance. This view has faced an important objection, namely that (...) remote utterances lead to Moorean paradoxes. In this paper, I defend the remote utterance view against this objection and further develop the view. I argue that worries about Moorean paradoxes can easily be dispelled if we take into consideration the artifactual nature of recording devices, their materiality, and the communicative affordances they bring about. In the first section, we’ll present the answering machine paradox and give a brief overview of the remote utterance view. The second section presents the objection against the view, while the third gives a detailed rejoinder to the objection. Answering this objection is important also because it allows us to explore some underdeveloped aspects of the remote utterance view. First, I will discuss how the theorist calibrates her model with the data she seeks to explain and predict. Secondly, I will argue that speech acts performed via recording devices have different felicity conditions than their oral counterparts. I conclude with a short discussion of some semantic and pragmatic consequences of the view. (shrink)

In the last twenty years, recorded messages and written notes have become a significant test and an intriguing puzzle for the semantics of indexical expressions (see Smith 1989, Predelli 1996, 1998a,1998b, 2002, Corazza et al. 2002, Romdenh-Romluc 2002). In particular, the intention-based approach proposed by Stefano Predelli has proven to bear interesting relations to several major questions in philosophy of language. In a recent paper (Saul 2006), Jennifer Saul draws on the literature on indexicals and recorded messages in order to (...) criticize Rae Langton's claim that works of pornography can be understood as illocutionary acts – in particular acts of subordinating women or acts of silencing women. Saul argues that it does not make sense to understand works of pornography as speech acts, because only utterances in contexts can be speech acts. More precisely, works of pornography such as a film may be seen as recordings that can be used in many different contexts – exactly like a written note or an answering machine message. According to Saul, bringing contexts into the picture undermines Langton's radical thesis – which must be reformulated in much weaker terms. In this paper, I accept Saul's claim that only utterances in contexts can be speech acts, and that therefore only works of pornography in contexts may be seen as illocutionary acts of silencing women. I will, nonetheless, show that Saul's reformulation doesn't undermine Langton's thesis. To this aim, I will use the distinction Predelli proposes in order to account for the semantic behaviour of indexical expressions in recorded messages – namely the distinction between context of utterance and context of interpretation.

Recording devices are generally taken to present problems for the standard Kaplanian semantics for indexicals. In this paper, I argue that the remote utterance view offers the best way for the Kaplanian semantics to handle the recalcitrant data that comes from the use of recording devices. Following Sidelle I argue that recording devices allow agents to perform utterances at a distance. Using the essential, but widely ignored, distinction between tokens and utterances, I develop the view beyond the initial sketch given (...) by Sidelle, and I answer the main objections raised against the view. The paper is structured as follows. Section 1 gives a succinct presentation of Kaplanian semantics and of the problem raised by the use recording devices, Section 2 presents the remote utterance view and Section 3 answers the objections put forward against the view and further develops it. I conclude that the remote utterance view can handle the data that comes from the use of recording devices with only modest modifications of the Kaplanian semantics. (shrink)

Francois Recanati’s Mental Files presents a picture of the mind on which mental representations are indexical and transparent. I dispute this picture: there is no clear case for regarding mental representations as indexical, and there are counterexamples to transparency.

Stewart Cohen’s New Evil Demon argument raises familiar and widely discussed concerns for reliabilist accounts of epistemic justification. A now standard response to this argument, initiated by Alvin Goldman and Ernest Sosa, involves distinguishing different notions of justification. Juan Comesaña has recently and prominently claimed that his Indexical Reliabilism (IR) offers a novel solution in this tradition. We argue, however, that Comesaña’s proposal suffers serious difficulties from the perspective of the philosophy of language. More specifically, we show that the two (...) readings of sentences involving the word ‘justified’ which are required for Comesaña’s solution to the problem are not recoverable within the two-dimensional framework of Robert Stalnaker to which he appeals. We then consider, and reject, an attempt to overcome this difficulty by appeal to a complication of the theory involving counterfactuals, and conclude the paper by sketching our own preferred solution to Cohen’s New Evil Demon.

I critically examine Cappelen and Lepore’s definition of and tests for indexicality, and refine them to improve their adequacy. Indexicals cannot be defined as expressions with different referents in different contexts unless linguistic meaning and circumstances of evaluation are held constant. I show that despite Cappelen and Lepore’s claim that there are only a handful of indexical expressions, their “basic set” includes a number of large and open classes, and generates an infinity of indexical phrases. And while the tests (...) can be used effectively to combat contextualism concerning ‘knows’ and ‘actual,’ many expressions not in their basic set test positive for indexicality, including quantifier nouns, weather reports, and comparative adjectives. I rebut their claim that context-shifting arguments inevitably lead to radical contextualism, and that if there were any indexicals beyond their basic set, communication would be impossible.

This paper argues that a theory of situated vision, suited for the dual purposes of object recognition and the control of action, will have to provide something more than a system that constructs a conceptual representation from visual stimuli: it will also need to provide a special kind of direct (preconceptual, unmediated) connection between elements of a visual representation and certain elements in the world. Like natural language demonstratives (such as `this' or `that') this direct connection allows entities to be (...) referred to without being categorized or conceptualized. Several reasons are given for why we need such a preconcep- tual mechanism which individuates and keeps track of several individual objects in the world. One is that early vision must pick out and compute the relation among several individual objects while ignoring their properties. Another is that incrementally computing and updating representations of a dynamic scene requires keeping track of token individuals despite changes in their properties or locations. It is then noted that a mechanism meeting these requirements has already been proposed in order to account for a number of disparate empiri- cal phenomena, including subitizing, search-subset selection and multiple object tracking (Pylyshyn et al., Canadian Journal of Experimental Psychology 48(2) (1994) 260). This mechanism, called a visual index or FINST, is brie. (shrink)

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence φ allows for cases in which one party utters φ and the other its negation, and neither party’s claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a (...) doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other’s claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the par- ties to reject each other’s claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. e existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well. (shrink)

I propose a pragmatic approach to the kind of reference-shifting occurring in indexicals as used in e.g. written notes and answering machine messages. I proceed in two steps. First, I prepare the ground by showing that the arguments against such a pragmatic approach raised in the recent literature fail. Second, I take a first few steps towards implementing this approach, by sketching a pragmatic theory of reference-shifting, and showing how it can handle cases of the relevant kind. While the immediate (...) scope of the paper is restricted to indexicals and reference-shifting, and the discussion is confined to a specific range of theories and cases, the approach proposed is compatible with a fairly broad range of more or less semantically conservative theories, and many of the conclusions drawn are significant for the evaluation of pragmatic explanations in philosophy more generally. The overall goal is to offer a new perspective on the issues under discussion, and to prompt philosophers to reconsider some of the established methods by which pragmatic explanations are evaluated.

We distinguish, among other things, between the agent of the context, the speaker of the agent's utterance, the mechanism the agent uses to produce her utterance, and the tokening of the sentence uttered. Armed with these distinctions, we tackle the the ‘answer-machine’, ‘post-it note’ and other allegedly problematic cases, arguing that they can be handled without departing significantly from Kaplan's semantical framework for indexicals. In particular, we argue that these cases don't require adopting Stefano Predelli's intentionalism.

We present a computational analysis of de re, de dicto, and de se belief and knowledge reports. Our analysis solves a problem first observed by Hector-Neri Castañeda, namely, that the simple rule -/- `(A knows that P) implies P' -/- apparently does not hold if P contains a quasi-indexical. We present a single rule, in the context of a knowledge-representation and reasoning system, that holds for all P, including those containing quasi-indexicals. In so doing, we explore the difference between reasoning (...) in a public communication language and in a knowledge-representation language, we demonstrate the importance of representing proper names explicitly, and we provide support for the necessity of considering sentences in the context of extended discourse (for example, written narrative) in order to fully capture certain features of their semantics.

L'Index scolastico-cartesien elabore par Etienne Gilson se concoit avant tout comme un instrument de travail apportant des materiaux pour l'application d'une these audacieuse qui sera plus tard developpee dans les Etudes sur le role de la pensee medievale dans la formation du systeme cartesien, et que Gilson inaugure en ces termes : On a longtemps considere que le principal titre de gloire de Bacon et Descartes avait ete de constituer une philosophie radicalement detachee de toutes les philosophies anterieures, et d'en (...) construire l'edifice entier a nouveaux frais. [...] Une pareille conception du cartesianisme peut a la limite se soutenir en ce qui concerne la physique, mais la psychologie, la doctrine de la connaissance, la morale et la metaphysique de Descartes sont remplies d'elements empruntes a la scolastique. La doctrine du temps, des elements et qualites des corps, de Dieu et de ses attributs, des preuves de son existence, de la creation et conservation du monde, de la substance et de son rapport aux accidents, des idees innees et de notre mode de connaissance, des etats actifs et passifs de l'ame, du rapport de la volonte a l'entendement, enfin les vues de Descartes sur la religion et ses rapports avec la philosophie temoignent que sa pensee n'est pas sans devoir quelque chose a la philosophie de l'Ecole.

Eros Corazza presents a fascinating investigation of the role that indexicals play in our thought. Indexicality is crucial to the understanding of such puzzling issues as the nature of the self, the nature of perception, social interaction, psychological pathologies, and psychological development. Corazza draws on work from philosophy, linguistics, and psychology to illuminate this key aspect of the relation between mind and world. By highlighting how indexical thoughts are irreducible and intrinsically perspectival, Corazza shows how we can depict someone (...) else's indexical thought from a third-person perspective. The phenomenon of quasi-indexicality is introduced here: to represent Jane saying, "I am prosperous", we use what Castañeda termed a quasi-indicator in a report of the form "Jane said that she is prosperous". Corazza argues that quasi-indicators play such an important role in our linguistic, social, and psychological life that they have a cognitive primacy over other mechanisms of reference. Quasi-indexicality also emerges as a key notion when we come to consider our ability to understand other minds. Corazza argues that indexicality and quasi-indexicality are two sides of the same coin, best understood within the framework of direct reference. (shrink)

This book argues that there is a common cognitive mechanism underlying all indexical thoughts, in spite of their seeming diversity. Indexical thoughts are mental representations, such as beliefs and desires. They represent items from a thinker's point of view or her cognitive perspective. We typically express them by means of sentences containing linguistic expressions such as 'this ' or 'that ', adverbs like 'here', 'now', and 'today', and the personal pronoun 'I'. While generally agreeing that representing the world from a (...) thinker's cognitive perspective is a key feature of indexical thoughts, philosophers disagree as to whether a thinker's cognitive perspective can be captured and rationalized by semantic content and, if so, what kind of content this is. This book surveys competing views and then advances its own positive account. Ultimately, it argues that a thinker's cognitive perspective - or her indexical point of view - is to be explained in terms of the content that is believed and asserted as the only kind of content that there is which thereby serves as the bearer of cognitive significance. The Indexical Point of View will be of interest to philosophers of mind and language, linguists, and cognitive scientists. (shrink)

Indexicals are unique among expressions in that they depend for their literal content upon extra-semantic features of the contexts in which they are uttered. Taking this peculiarity of indexicals into account yields solutions to variants of Frege's Puzzle involving objects of attitude-bearing of an indexical nature. If names are indexicals, then the classical versions of Frege's Puzzle can be solved in the same way. Taking names to be indexicals also yields solutions to tougher, more recently-discovered puzzles such as Kripke's well-known (...) case involving Paderewski. We argue that names are in fact rigidly designating indexicals. We also argue that fully developed, the direct reference theory's best strategy for solving the puzzles amounts to the adoption of the indexical theory of names – a move that we argue should be thought of as a natural development of the direct reference theory, and not as antagonistic to it.

Existing indexing systems used to arrange philosophical works have been shown to misrepresent the discipline in ways that reflect and perpetuate exclusionary attitudes within it. In recent years, there has been a great deal of effort to challenge those attitudes and to revise them. But as the discipline moves toward greater equality and inclusivity, the way it has indexed its work has unfortunately not. To course correct, we identify in this article some of the specific changes that are needed within (...) current indexing systems and propose a new model that could embody them. We use the Diversity Reading List in Philosophy as a case study and PhilPapers as a basis for comparison. The model we propose not only represents the discipline in a more inclusive and fair way, but it is also efficient, easy to use or implement, and adaptable for a variety of contexts. (shrink)

This paper advances the thesis that sensory concepts have as a semantic component the first-person indexical. It is argued that the private nature of our access to our own sensations forces, in our talking about them, an indexical reference to the inner states of the speaker in lieu of publicly accessible properties by which reference is usually fixed. Indexicals, such as ‘here’, can be understood despite ignorance of their referent. Such is the case with sensory terms. Furthermore, the thesis that (...) sensory terms are indexical has considerable explanatory power. I give two examples: firstly, I argue that clashes of intuition over Block's ‘inverted spectrum’ thought experiment can be explained by appeal to semantic properties of indexicals. Secondly, I argue that multiple realisability intuitions can be shown to be consistent with the view that sensations are type-identical with brain states. (shrink)

An ω-language is a set of infinite sequences on a countable language, and corresponds to a set of real numbers in a natural way. Languages may be described by logical formulas in the arithmetical hierarchy and also may be described as the set of words accepted by some type of automata or Turing machine. Certain families of languages, such as the equation image languages, may enumerated as P0, P1, … and then an index set associated to a given property R (...) of languages is just the set of e such that Pe has the property. The complexity of index sets for 7 types of languages is determined for various properties related to the size of the language. (shrink)

When you use the word “I” it designates you; when I use the same word, it designates me. If you use “you” talking to me, it designates me; when I use it talking to you, it designates you. “I” and “you” are indexicals. The designation of an indexical shifts from speaker to speaker, time to time, place to place. Different utterances of the same indexical designate different things, because what is designated depends not only on the meaning associated with the (...) expression, but also on facts about the utterance. An utterance of “I” designates the person who utters it; an utterance of “you” designates the person to whom it is addressed, an utterance of “here” designates the place at which the utterance is made, and so forth. Because indexicals shift their designation in this way, sentences containing indexicals can be used to say different things on different occasions. Suppose you say to me, “You are wrong and I am right about reference,” and I reply with the same sentence. We have used the same sentence, with the same meaning, but said quite different and incompatible things. (shrink)

In this essay I examine how we use indexicals. The key function of indexicals, I claim, is to help the audience --- that is the hearers or readers of the utterance with whom the speaker intends to be communicating---to find supplementary channels of information about the object to which the indexical refers. To keep the discussion manageable, I will oversimplify the epistemology of conversation. I ignore the fact that people sometimes lie and sometimes make mistakes. I talk freely about what (...) one learns and the information one gets from an utterance. (shrink)

The main purpose of this paper is to characterize and compare two forms any relativist thesis can take: indexical relativism and genuine relativism. Indexical relativists claim that the implicit indexicality of certain sentences is the only source of relativity. Genuine relativists, by contrast, claim that there is relativity not just at the level of sentences, but also at propositional level. After characterizing each of the two forms and discussing their difficulties, I argue that the difference between the two is (...) significant. (shrink)

To avoid difficulties facing intention-based accounts of indexicals, Cohen () recently defends a conventionalist account that focuses on the context of tokening. On this view, a token of ‘here’ or ‘now’ refers to the place or time at which it tokens. However, although promising, such an account faces a serious problem: in many speech acts, multiple apparent tokens are produced. If I call Alaska from Paris and say ‘I'm here now’, an apparent token of my utterance will be produced in (...) both Paris and Alaska. The token-contextual account seems to imply that in such cases I will refer to both places and contradict myself. Here I argue that to resolve this and similar puzzles we must realize that not all apparent semantic tokens really are semantic tokens, and that to decide which ones count we must appeal to speaker intentions. However, because this appeal is made at the level of the metaphysics of semantic tokens rather than to determine their meaning, it does not raise the problems associated with intentionalism that the conventionalist hopes to avoid. The metaphysics of semantic tokens uncovered is surprisingly complex, showing that shapes and sounds can transition in and out of being utterances. (shrink)
