In this paper I argue for a non-referential interpretation of some uses of indexicals embedded under epistemic modals. The so-called descriptive uses of indexicals come in several types and it is argued that those embedded within the scope of modal operators do not require non-referential interpretation, provided the modality is interpreted as epistemic. I endeavor to show that even if we allow an epistemic interpretation of modalities, the resulting interpretation will still be inadequate as long as we (...) retain a referential interpretation of indexicals. I then propose an analysis of descriptive indexicals that combines an epistemic interpretation of modality with a non-referential interpretation of indexicals. (shrink)

We assume a central thesis about modal auxiliaries due to Angelika Kratzer, the modal base presupposition: natural language expressions that contain a modal component in their meaning, including all English modal auxiliaries and epistemic modal auxiliaries (EMA)s in particular, presuppose a modal base, a function that draws from context a relevant set of propositions which contribute to a premise-semantics for the modal. Accepting this thesis for EMAs leaves open (at least) the following two questions about the meaning of English (...) EMAs like _must_ and _might_: (i) What constraints, if any, are there on the character of the premise set for an EMA? And (ii) what is the nature of the relationship between premises and conclusion that is required for truth of the EMA statement? I argue for at least a partial answer to (i), with a hypothesis about constraints on the modal base for an EMA: EMAs, unlike some other types of modals, are indexical: They are anchored to an agent-in-a-situation whose doxastic state is currently under discussion in the context of utterance. Realized in a Kratzerian semantics, indexicality sheds new light on a number of outstanding puzzles, including the widely observed variability of anchoring of EMAs, the ways in which EMAs differ from so-called root modals, Yalcin’s (Mind 116:983–1026, 2007) puzzle (a version of Moore’s paradox for epistemic modals embedded under attitudes), how to explain the apparent weakness of necessity EMAs, and problems with second order belief and disagreement.

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)

The verb 'knows' is often taken to be context-sensitive in an interesting way. What 'knows' means seems to be sensitive to the epistemic features of the context, e.g. the epistemic standard in play, the set of relevant alternatives, etc. There are standard model-theoretic semantic frameworks which deal with both intensional operators and context-sensitive expressions. In this chapter, we provide a brief overview of the various moving parts of these frameworks, the roles of context and index, the need for (...) double indexing, and the relationship between semantic value and content. With the best version of the standard framework explicated we then return at the end to the treatment of ‘know’ as a context-sensitive intensional operator (contrasting it with an invariantist treatment). (shrink)

Theorists with otherwise radically different commitments agree that epistemic modals mark the necessity or possibility of a prejacent proposition relative to a body of evidence or knowledge. However, there is vast disagreement about the semantics of epistemic modals, which stems in part from the fact that statements of epistemic possibility or necessity make no explicit reference to a speaker or group, an audience, or an evidence set. This volume introduces new philosophical papers that mark a significant contribution (...) to the debate about epistemic modals. (shrink)

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.

In the first part of this paper I sketch a theory of indexical concepts within a broadly epistemic framework. In the second part I discuss and dismiss an argument due to Jerry Fodor, to the effect that any epistemic approach to concept individuation (including the theory of indexical concepts I will sketch) is doomed to failure.

This thesis consists of four essays and an introduction dedicated to two main topics: indexicality and presupposition. The first essay is concerned with an alleged problem for the standard treatment of indexicals on which their linguistic meanings are functions from context to content. Since most indexicals have their content settled, on an occasion of use, by the speaker’s intentions, some authors have argued that this standard picture is inadequate. By demonstrating that intentions can be seen as a parameter of the (...) kind of context that characters operate on, these arguments are rejected. In addition, it is argued that a more recent, variable-based framework is naturally interpreted as an intention-sensitive semantics. The second essay is devoted to the phenomenon of descriptive uses of indexicals on which such an expression seems to contribute, not its standard reference as determined by its character, but a property to the interpretation. An argument that singular readings of the cases in question are incoherent is shown to be incorrect, and an approach to descriptive readings is developed on which they arise from e-type uses akin to other well known cases. Further, descriptive readings of the relevant kind are seen to arise only in the presence of adverbs of quantification, and all sentences in which such an adverb takes scope over an indexical are claimed to be ambiguous between a referential and an e-type reading. The third essay discusses a version of the variable analysis of pronouns on which their descriptive meanings are relegated to the so-called phi-features – person, gender and number. In turn, the phi-features are here seen as triggering semantic presuppositions that place constraints on the definedness of pronouns, and ultimately of sentences in which they appear. It is argued that the descriptive information contributed by the phi-features diverges radically from presuppositional information of both semantic and pragmatic varieties on several dimensions of comparison, and instead the main role of the phi-features is seen to be that of guiding hearers’ attempts to ascertain the speaker’s intentions. The fourth essay addresses an issue concerning the treatment of presuppositions in dynamic semantics. Representing a semantic treatment of pragmatic presuppositions, the dynamic framework is shown to incorrectly regard conversational infelicity as sufficient for semantic undefinedness, given the standard way of defining truth in terms of context change. Further, it is shown that a proposal for a solution fail to make correct predictions for epistemic modals. A novel framework is developed on which context change potentials act on contexts that have more structure than the contexts usually countenanced by dynamic semantics, and it is shown that this framework derives truth from context change while making correct predictions for both presuppositions and modals.

Reference and indexicality are two central topics in the Philosophy of Language that are closely tied together. In the first part of this book, a description theory of reference is developed and contrasted with the prevailing direct reference view with the goal of laying out their advantages and disadvantages. The author defends his version of indirect reference against well-known objections raised by Kripke in Naming and Necessity and his successors, and also addresses linguistic aspects like compositionality. In the second part, (...) a detailed survey on indexical expressions is given based on a variety of typological data. Topics addressed are, among others: Kaplan's logic of demonstratives, conversational versus utterance context, context-shifting indexicals, the deictic center, token-reflexivity, vagueness of spatial and temporal indexicals, reference rules, and the epistemic and cognitive role of indexicals. From a descriptivist perspective on reference, various examples of simple and complex indexicals are analyzed in first-order predicate logic with reified contexts. A critical discussion of essential indexicality, de se readings of attitudes and accompanying puzzles rounds up the investigation. (shrink)

There are two issues I want to very briefly raise in response to Robin McKenna’s paper, “Epistemic Contextualism, Epistemic Relativism, and Disagreement.” First, I want to question whether or not the disagreement problem faced by indexical contextualism is truly a problem. Secondly, I want to consider whether or not McKenna’s solution is really in keeping with indexical contextualism.

In this paper I try to challenge some received views about the role and the function of the traditional academic practice of publishing papers in peer?reviewed journals. I argue that our publishing practices today are rather based on passively accepted social norms and humdrum work habits than on actual needs for communicating the advancements of our research. By analysing some examples of devices and practices that are based on tacitly accepted norms, such as the Citation Index and the new role (...) of DOI attributions in digital publishing, I advocate an epistemically vigilant stance not only towards our ways of acquiring knowledge, but also towards the implicit norms we accept when we produce research.

State‐of‐the‐art surveys such as John H. Zammito has produced are usually read prior to engaging seriously upon some course of study. Yet his book will be even more helpful, perhaps, to those who can look retrospectively upon the field of science studies in order to consider how the field has changed and whether postmodernism remains the threat that Zammito thinks it. By explicitly including the history of the development of the philosophy of language in a history of science studies, he (...) makes an original, provocative claim that goes beyond the wealth of information on Quine and Kuhn’s supposed refutation of the Vienna Circle’s positivism, the creation of the Edinburgh School’s sociology of scientific knowledge (SSK), and the debates that followed in the wake of each. Analytic philosophers from Quine to Rorty and Continental philosophers from Derrida to the postmoderns thus play a central role in the development of science studies, despite the fact that they focus on language in general rather than on science.

The paper presents an epistemic logic with quantification over agents of knowledge and with a syntactical distinction between de re and de dicto occurrences of terms. Knowledge de dicto is characterized as ‘knowledge that’, and knowlegde de re as ‘knowledge of’. Transition semantics turns out to be an adequate tool to account for the distinctions introduced.

Does game theory—the mathematical theory of strategic interaction—provide genuine explanations of human behaviour? Can game theory be used in economic consultancy or other normative contexts? Explaining Games: The Epistemic Programme in Game Theory—the first monograph on the philosophy of game theory—is an attempt to combine insights from epistemic logic and the philosophy of (...) science to investigate the applicability of game theory in such fields as economics, philosophy and strategic consultancy. I prove new mathematical theorems about the beliefs, desires and rationality principles of individual human beings, and explore in detail the logical form of game theory as it is used in explanatory and normative contexts. I argue that game theory reduces to rational choice theory if used as an explanatory device, and that game theory is nonsensical if used as a normative device. A provocative account of the history of game theory reveals that this is not bad news for all of game theory, though. Two central research programmes in game theory tried to find the ultimate characterisation of strategic interaction between rational agents. Yet, while the Nash Equilibrium Refinement Programme has done badly thanks to such research habits as overmathematisation, model-tinkering and introversion, the Epistemic Programme, I argue, has been rather successful in achieving this aim. "The 'epistemic' approach to game theory has emerged over the past twenty-five years. What is this approach? How does it differ from the conventional equilibrium-based approach to game theory? What have been its strengths and weaknesses to date? To find out, read this comprehensive and excellently written account". Adam Brandenburger, J. P. Valles Professor of Business Economics and Strategy, Stern School of Business, New York University "Reading Boudewijn de Bruin's book should be rewarding both for game theorists interested in the conceptual foundations of their discipline and for philosophers who want to learn more about formal analysis of strategic interaction. It provides an in-depth logical study of the currently dominant epistemic approaches to non-cooperative games, with an eye both to the attractions and to the serious challenges facing the Epistemic Programme".

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality is preserved via (...) purely abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

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)

How do words stand for things? Taking ideas from philosophical semantics and pragmatics, this book offers a unique, detailed, and critical survey of central debates concerning linguistic reference in the twentieth century. It then uses the survey to identify and argue for a novel version of current 'two-dimensional' theories of meaning, which generalise the context-dependency of indexical expressions. The survey highlights the history of tensions between semantic and epistemic constraints on plausible theories of word meaning, from analytic philosophy and (...) modern truth-conditional semantics, to the Referentialist and Externalist revolutions in theories of meaning, to the more recent reconciliatory ambition of two-dimensionalists. It clearly introduces technical semantical notions, theses, and arguments, with easy-to-follow, step-by-step guides. Wide-ranging in its scope, yet offering an accessible route into literature that can seem complex and technical, this will be essential reading for advanced students, and academic researchers in semantics, pragmatics, and philosophy of language.

Terence Horgan defends the thirder position on the Sleeping Beauty problem, claiming that Beauty can, upon awakening during the experiment, engage in “synchronic Bayesian updating” on her knowledge that she is awake now in order to justify a 1/3 credence in heads. In a previous paper, I objected that epistemic probabilities are equivalent to rational degrees of belief given a possible epistemic situation and so the probability of Beauty’s indexical knowledge that she is awake now is necessarily 1, (...) precluding such updating. In response, Horgan maintains that the probability claims in his argument are to be taken, not as claims about possible rational degrees of belief, but rather as claims about “quantitative degrees of evidential support.” This paper argues that the most plausible account of quantitative degree of support, when conjoined with any of the three major accounts of indexical thought in such a way as to plausibly constrain rational credence, contradicts essential elements of Horgan’s argument.

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.

Grice’s Razor is a methodological principle that many philosophers and linguists have used to help justify pragmatic explanations of linguistic phenomena over semantic explanations. A number of authors in the debate over contextualism argue that an invariant semantics together with Grice’s (1975) conversational principles can account for the contextual variability of knowledge claims. I show here that the defense of Grice’s Razor found in these “Gricean invariantists,” and its use against epistemic contextualism, display all the problems pointed out earlier (...) in Davis (1998). The everyday variation in acceptable knowledge claims is better explained in terms of implicature than indexicality, but general conversational principles shed little light on whether ‘know’ is used hyperbolically, meiotically, or loosely in a context, although this issue is crucial in deciding what if anything ‘S knows p’ implicates. I present reasons favoring an account of the representative bank case in terms of loose use, making clear how they differ from Grice’s Razor. (shrink)

Although the members’ categories associated with institutional settings may seem obvious, more can be said about the actions that make them noticeable and persistent across contexts. This study investigates how epistemic stance displays make the standardized relational pair ‘teacher–student’ relevant during writing conferences in a US university. Analysis of the interaction between teachers and their students shows that teachers tended to display more knowledgeable stances concerning writing and institutional practices, whereas students displayed knowledgeable stances with respect to their own (...) papers, indexing the immediate relevance of the ‘teacher–student’ relational pair and a tension between authority and autonomy. Further analysis reveals that participants also mentioned past and future writing activities, thus indexing the persistence of the ‘teacher–student’ pair as well as the emergence of the category ‘autonomous writer’. Additionally, participants’ orientation to the more general ‘writer–reader’ pair also functioned to index the persistent and emergent aspects of these categories. (shrink)

Inspired by two-dimensional modal logic, some have sought to provide analyses of the notion of the contingent a priori which identify the a priori with truths which have a necessary diagonal. I argue that these analyses fail insofar as they miss the crucial epistemic aspect of the a priori. Augmenting these analyses with specifically epistemic accounts might be possible, but the interest would then reside in these epistemic accounts of the a priori and not in the formal (...) models.

One of the fundamental properties inclassical equational reasoning isLeibniz's principle of substitution. Unfortunately, this propertydoes not hold instandard epistemic logic. Furthermore,Herbrand's lifting theorem which isessential to thecompleteness ofresolution andParamodulation in theclassical first order logic (FOL), turns out to be invalid in standard epistemic logic. In particular, unlike classical logic, there is no skolemization normal form for standard epistemic logic. To solve these problems, we introduce anintensional epistemic logic, based on avariation of Kripke's possible-worlds semantics that need (...) not have a constant domain. We show how a weaker notion of substitution through indexed terms can retain the Herbrand theorem. We prove how the logic can yield a satisfibility preserving skolemization form. In particular, we present an intensional principle for unifing indexed terms. Finally, we describe asound andcomplete inference system for a Horn subset of the logic withequality, based onepistemic SLD-resolution. (shrink)

This article looks at Husserlian ideas as an analytical tool to explain the cognitive aspects of experiences that range between knowledge acts in inferences and Mulligan’s contemporary perspective of meaning formation, through reflections of relations. The essay also takes into consideration the views of Levinas and Hintikka, for whom experiences form the foundations of intuitive capacity. These perspectives are essential concerning epistemic evidence to self (I/me-ness): mental objects and spatiotemporal relations are the structural notions of episteme on their own; (...) their dynamics were tightly coordinated at an intentional process to strengthen episteme; this coordination appeared to be a state change caused in epistemic evidence.

By an incomplete sentence we shall understand a declarative sentence that can be used, without variation in its meaning, to make different statements in different contexts. Although the point deserves supporting argument, which we will not provide, sentences whose grammatical subjects are indexical expressions or demonstratives are obvious, plausible examples of incomplete sentences. Uttered in one context the sentence ‘He is ill’ may be used to make one statement, for example, that George is ill, while in another context the very (...) same sentence may be used to make a quite different statement, for example, that Paul is ill.

Within the philosophy of mind, consciousness is currently understood as the expression of one or other cognitive modality, either intentionality , transparency , subjectivity or reflexivity . However, neither intentionality, subjectivity nor transparency adequately distinguishes conscious from nonconscious cognition. Consequently, the only genuine index or defining characteristic of consciousness is reflexivity, the capacity for autonoetic or self-referring, self-monitoring awareness. But the identification of reflexivity as the principal index of consciousness raises a major challenge in relation to the cognitive mechanism responsible (...) for operationalizing such a reflexive state. Current reliance by higher-order and intrinsic self-representational theories on self-representing data structures to achieve reflexive self-awareness is highly problematic, suggesting a solution in terms of a self-referential processing regime.

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.

In my commentary, I first challenge Chakravartty’s claim that naturalized metaphysics cannot be indexed to science simpliciter.

Third, I argue that it is unclear what stops epistemic stances from having unlimited influence. Finally, I (...) argue that Chakravartty’s epistemic stance voluntarism is inadequately motivated and lacks empirical support for its psychological content. (shrink)

1) We will begin by offering a short introduction to Epistemic Logic and presenting Fitch’s paradox in an epistemic‑modal logic. (2) Then, we will proceed to presenting three Epistemic Temporal logical frameworks creat‑ ed by Hoshi (2009) : TPAL (Temporal Public Announcement Logic), TAPAL (Temporal Arbitrary Public Announcement Logic) and TPAL+P ! (Temporal Public Announcement Logic with Labeled Past Operators). We will show how Hoshi stated the Verificationist Thesis in the language of TAPAL and analyze his argument (...) on why this version of it is immune from paradox. (3) Edgington (1985) offered an interpretation of the Verificationist Thesis that blocks Fitch’s paradox and we will propose a way to formulate it in a TAPAL‑based lan‑ guage.

Using indexed satisfi‑ ability relations (as introduced in (Wang 2010 ; 2011)) we will offer a prospec ‑ tive semantics for this language. We will investigate whether the tentative re‑ formulation of Edgington’s Verificationist Thesis in TAPAL+P !+P is free from paradox and adequate to Edgington’s ideas on how „all truths are knowable“ should be interpreted.

Philosophers of science typically focus on the epistemic performance of scientific models when evaluating them. Analysing the effects that models may have on the world has typically been the purview of sociologists of science. We argue that the reactive (or “performative”) effects of models should also figure in model evaluations by philosophers of science. We provide a detailed analysis of how models in financial economics created the impetus for the growing importance of the phenomenon of “passive investing” in financial (...) markets. Considering this case motivates the position that we call contextualism about model evaluation, or _model contextualism_ for short. Model contextualism encompasses standard analyses of the epistemic performance of the model, but also includes their reactive aspects. It entails identifying the _epistemic and contextual import of the model_, the ways in which a model can engender change in the world (which we call the _channels of transmission_), and the _interactions between the epistemic and reactive import of a model_.

Both because of the non-epistemic consequences of the inquiry related to its inductive risk and because such inquiry is a case in which there is legitimate and necessary integration between epistemic and non-epistemic values and that it is also a case in which Douglas’ criteria of objectivity is reached. By virtue of these reasons, the significance of Douglas’ contribution to the analysis of the relationship between science and politics is emphasized. (shrink)

Epistemic Contextualism is generally treated as a semantic thesis that may or may not have epistemological consequences. It is sometimes taken to concern only knowledge claims (as the assertion that the word “know” means different things in different contexts of use). Still, at other times it is taken to regard the knowledge relation itself (as the assertion that knowledge itself has no single univocal nature). Call the former view Semantic EC, the latter view Substantive EC, and the idea that (...) the plausibility of Semantic EC presupposes that of Substantive EC, the “Presupposition Thesis.” Numerous authors argue against the Presupposition Thesis on the grounds that an understanding of the nature of knowledge is no more required to understand the meaning of knowledge assertions than an understanding of the self, for instance, is needed to understand the meaning of sentences containing “I.” These authors then offer additional arguments for the same conclusion, using further comparisons between “know” and other indexicals, as well as between “know” and quantifiers, gradable and modal adjectives. Herein, I defend the Presupposition Thesis by arguing against these authors’ claims (based as they are on these types of comparisons) that Semantic EC is plausible without the supposition of Substantive EC.

The expression ‘Oh’ in natural conversation is a signal topic in the development of the Epistemic Program. This article attempts to bring into view a sense of place for this simple expression in the early literature, beginning with ‘Oh’ as a ‘change-of-state token’ and through its subsequent treatments in the production of assessments. It reviews them with an interest in two allied developments. One is the rendering of ‘Oh’ as an expression that ‘indexes’ epistemic structure. The other, pursued (...) in the detail of transcript in Part 2, is how, as of this rendering, the literature manages its tasks of ‘animating transcript’, or how we portray ordinary talk as social action. We think these two moves are closely connected within the EP. And we think they yield a very different ‘vocabulary of motives’, different from the natural language studies of conversation analysis. Our discussions address in turn the central phrases of our title. (shrink)

Are indices a purely linguistic, textual phenomenon or are linguistic indices a special case of a more general type of indexical signs? In comparing Carlo Ginzburg's restrictive view of indices and traces in particular with Peirce's general approach to indexical signs, this paper argues that Peirce's account of indexicality makes it possible to connect the sciences and the humanities by a flexible relational concept of the epistemic function of an identification that indexical experiences allows for. In this way Peirce's (...) flexible concept of indexicality allows us to connect e.g. the experience of a condensation trace of an electron in a cloud chamber with that of the trace of a deer in the snow.
