In “Complex Demonstratives: A Quantificational Account” (MIT Press 2001) (henceforth CD), I argued that complex demonstratives are quantifiers. Many philosophers had held that demonstratives, both simple and complex, are referring terms. Since the publication of CD various objections to the account of complex demonstratives I defended in it have been raised. In the present work, I lay out these objections and respond to them.

This paper presents a semantic and pragmatic theory of complex demonstratives. According to this theory, the semantic content of a complex demonstrative, in a context, is simply an object, and the semantic content of a sentence that contains a complex demonstrative, in a context, is a singular proposition. This theory is defended from various objections to direct reference theories of complex demonstratives, including King's objection from quantification into complex demonstratives.

ABSTRACT: Complex demonstratives raise problems in semantics and force a re-examination of basic principles underlying the New Theory of Reference. First, I present these problems and the relevant principles. Then, I explore the most common suggestions, for instance, as those put forward by Braun and Dever. Finally, I introduce my own view. The latter is a non-ad hoc extension of the Reflexive-Referential analysis of context-sensitive terms as discussed by Perry. It accounts for familiar problems, including those raised by the (...) fact that sometimes the object referred to does not satisfy the nominal, nor preserve the relevant principles.RÉSUMÉ: Les demonstratifs complexes soulèvent des problèmes sémantiques majeurs qui incitent à l’examen de principes sous-jacents à la nouvelle théorie de la référence. Je présente ces problèmes de même que les principes qu’ils semblent remettre en question, expose les deux principales approches des démonstratifs (celIes défendue par Braun et par Dever) et, finalement, suggère une théorie inspirée destravaux de John Perry sur les expressions référentielles sensibles aux contextes d’énonciation. Ma façon d’aborder les démonstratifs complexes est un prolongement de l’approche réflexive référentielle et fait appel à de multiples propositions exprimées par des énonciations. (shrink)

Complex demonstrative phrases, in English, are phrases such as ‘that woman in the department’ and ‘that car on the corner’. They are of particular interest to philosophers for two related reasons. The first involves the problem of intentionality. If there are phrases that are candidates for “latching directly onto the world,” they are such phrases, and their “simple” counterparts, as in the occurrences of ‘that’ in ‘that is nice’. As a result, philosophers interested in intentionality, from the sense-data (...) theorists to contemporary philosophers of mind, have devoted considerable attention to the question of how a demonstrative thought links to its object. The second reason involves issues in semantics and the philosophy of language. In the course of investigations into the model theory for modal logic in the 1950s and 1960s, philosophers recognized that the simplest way to treat terms was as modally rigid, namely as designating their actual designations relative to any possible world in which they existed, and nothing else in other worlds. It was soon recognized that this semantic property could be elegantly explained by the assumption that the semantics of singular terms reflects the role of singular terms in linking representations directly to the world. If the semantic contribution of a singular term to a thought is simply the object it denotes, and the thought is the object of modal evaluation, then the modal rigidity of the class of terms falls out as a consequence. Demonstrative phrases, both simple and complex, have always been taken to be among the paradigms for this picture of reference, which has come to be known as “the direct reference” model. (shrink)

Jeffrey King has famously argued that there are several prima facie problems with the direct reference theory of the semantics of complex demonstratives, three of which apparently resist solution. King concludes by observing that, if these outstanding problems cannot be solved, then the prospects for a direct reference semantics for complex demonstratives will be poor. I shall focus on just one of these outstanding problems—the objection from belief attributions—and suggest that it, at least, can be answered.

I have two aims for the present paper, one narrow and one broad. The narrow aim is to show that a class of data originally described by Lynsey Wolter empirically undermine the leading treatments of complex demonstratives that have been described in the literature. The broader aim of the paper is to show that Wolter demonstratives, as I will call the constructions I focus on, are a threat not just to existing treatments, but to any possible theory that retains (...) the uncontroversial assumptions that relative clauses always form a constituent with the nouns they modify, and that semantic composition proceeds sequentially and locally, with the inputs to interpretation having the structure syntax tells us they do.

Some demonstrative expressions, those we might term ‘bare demonstratives’, appear without any appended descriptive content (e.g. occurrences of ‘this’ or ‘that’ simpliciter). However, it seems that the majority of demonstrative occurrences do not follow this model. ‘Complex demonstratives’ is the collective term I shall use for phrases formed by adjoining one or more common nouns to a demonstrative expression (e.g. ‘that cat’, ‘this happy man’) and I will call the combination of predicates immediately concatenated with the (...) demonstrative in such phrases the ‘matrix’ of the expression. The question, then, is how we should construe the logical form of such expressions within a semantic theory for our language; and I wish to suggest that some recent answers to this question are, in fact, mistaken. The structure of the paper is as follows: first, I wish to highlight two (often underlying) assumptions about the nature of noun phrases in general, and suggest that, if they are both adopted, they apparently constrain the possible accounts of the logical form of complex demonstratives to just three options. The second and third parts of the paper will be concerned with expanding these options and arguing that none of them are adequate; thus the major part of the paper is concerned with the negative claim that the most obvious moves to make in this area must actually fail on closer inspection. The fourth and final section will then (very briefly) sketch the positive thesis of the paper: that we can deliver a clear and cohesive account of complex demonstratives, armed simply with elements which we will draw from David Kaplan’s theory of demonstratives, but only at the cost of rejecting (or at least refining) one assumption we recognised initially.

Standard semantic theories predict that non-deictic readings for complex demonstratives should be much more widely available than they in fact are. If such readings are the result of a lexical ambiguity, as Kaplan (in: Almog, Perry, Wettstein (eds) Themes from Kaplan, Oxford University Press, Oxford, 1977) and others suggest, we should expect them to be available wherever a definite description can be used. The same prediction follows from ‘hidden argument’ theories like the ones described by King (Complex Demonstratives: (...) a Quantificational Account, MIT Press, Cambridge, 2001) and Elbourne (Situations and Individuals, MIT Press, Cambridge, 2005). Wolter (That’s That; the Semantics and Pragmatics of Demonstrative Noun Phrases. Ph.D. thesis, University of California at Santa Cruz, 2006), however, has shown that complex demonstratives admit non-deictic interpretations only when a precise set of structural constrains are met. In this paper, I argue that Wolter’s results, properly understood, upend the philosophical status quo. They fatally undermine the ambiguity theory and demand a fundamental rethinking of the hidden argument approach. (shrink)

result from combining the determiners `this' or `that' with syntactically simple or complex common noun phrases such as `woman' or `woman who is taking her skis off'. Thus, `this woman', and `that woman who is taking her skis off' are complex demonstratives. There are also plural complex demonstratives such as `these skis' and `those snowboarders smoking by the gondola'. My book Complex Demonstratives: A Quantificational Account argues against what I call the direct reference account of (...) class='Hi'>complex demonstratives (henceforth DRCD) and defends a quantificational account of complex demonstratives. In two recent papers, Nathan Salmon has criticized one of the book's arguments against DRCD. In this essay I show that Salmon's criticism fails. I also show that the version of DRCD that Salmon ends up endorsing is false. (shrink)

This seminar will investigate the semantics of complex demonstratives, that is phrases like that dog with a blue collar and this table where this or that is followed by an NP. There has been much debate recently on the overall semantic shape of these items, with some theorists (e.g. Braun) claiming that they are directly referential in the sense of Kaplan, some (e.g. King) claiming that they are quantificational, some (e.g. Roberts) claiming that they are to be treated as (...) definites in a dynamic semantics, and some (e.g. Elbourne) claiming that this and that are basically Fregean definite articles. Some of the discussion will involve presupposition and possible worlds semantics: does a sentence of the form That F is G (with speaker demonstration) express a proposition if the object demonstrated is not F ? and does the object demonstrated have to be F at an arbitrary world w in order for the proposition expressed by such a sentence to be true at w? Attention will also be paid to the nature of the proximal and distal features on this and that and their translation equivalents in other languages. (shrink)

I criticized Jeffrey King’s theory of complex demonstratives in “Problems for a Quantificational Theory of Complex Demonstratives.” King replied in “Complex Demonstratives as Quantifiers: Objections and Replies.” I here comment on some of King’s replies.

This squib presents a rebuttal to two of King’s (Complex demonstratives: A quantificational account. Cambridge, Mass.: MIT Press, 2001) arguments that complex demonstratives are quantifier phrases like every man. The first is in response to King’s argument that because complex demonstratives induce weak crossover effects, they are quantifier phrases. I argue that unlike quantifier phrases and like other definite determiner phrases, complex demonstratives in object position can corefer with singular pronouns contained in the subject DP. Although (...) complex demonstratives could undergo LF-movement, the ruling out by weak crossover is empirically undetectable. The second rebuttal is in response to King’s argument that because complex demonstratives allow antecedent-contained deletion, they are quantifier phrases. I present data showing that along with quantifier phrases, complex demonstratives pattern with proper names in allowing ACD with restrictive modification, but usually not with non-restrictive modification.

According to a straightforward, conservative account of English demonstratives, simple and complex demonstratives are referring expressions belonging to the same semantic category (but they could be understood as either terms or quantifiers); the denotation of a complex demonstrative “dF” (if it has one) must satisfy the nominal “F” in “dF”; and both simple and complex demonstratives function as rigid designators. According to a recent alternative advanced by Lepore and Ludgwig, simple and complex demonstratives belong to (...) different semantic categories (the former being terms while the latter are restricted quantifier phrases); the denotation of a complex demonstrative “dF”(if it has one) need not satisfy the nominal “F”; and complex demonstratives can have narrow scope, which implies that they do not always function as rigid designators. This paper provides evidence that supports the conservative account against the claims of Lepore and Ludwig’s alternative. (shrink)

In a recent book, Jeffrey King (King 2001) argues that complexdemonstratives, i.e., noun phrases of the form `this/that F, are not singular terms. As such,they are not devices of direct reference contributing the referent to the proposition expressed.In this essay I challenge King's position and show how a direct reference view can handle the datahe proposes in favor of the quantificational account. I argue that when a complex demonstrativecannot be interpreted as a singular term, it is best understood as (...) a case of deferredreference – in which case it should be viewed as an anaphora inheriting its value from a quantifiedterm – or as an emphatic description. (shrink)

Until recently it was standard to think that all demonstratives are directly referential. This assumption has played important roles in work on perception, reference, mental content, and the nature of propositions. But Jeff King claims that demonstratives with a nominal complement (like ‘that dog’) are quantifiers, largely because there are cases in which the semantic value of such a “complex demonstrative” is not simply an object (2001). Although I agree with King that such cases preclude a directly referential, (...) Kaplanian semantics for complex demonstratives, I will argue that without contentious further assumptions they do not vindicate King’s claim that they are quantifiers. This is because familiar pronouns act like King’s examples of complex demonstratives. Indeed, pronouns and complex demonstratives share behavior that even King overlooks. None of this pronoun behavior shows that pronouns are quantifiers, and similarly none of the analogous demonstrative behavior shows that complex demonstratives are quantifiers. (shrink)

Following Aristotle (who himself was following Parmenides), philosophers have appealed to the distributional reflexes of expressions in determining their semantic status, and ultimately, the nature of the extra-linguistic world. This methodology has been practiced throughout the history of philosophy; it was clarified and made popular by the likes of Zeno Vendler and J.L. Austin, and is realized today in the toolbox of linguistically minded philosophers. Studying the syntax of natural language was fueled by the belief that there is a conceptually (...) tight connection between the syntax of our language and its semantics, and the belief that there is a similarly tight connection between the semantics of our language and metaphysical facts about the world. We are less confident than our colleagues about the relation syntax has to semantics and metaphysics. In particular, we do not believe that the current status of theoretical syntax (or semantics or metaphysics) provides much support for either of the above two beliefs. We will illustrate our view with a case study regarding the status of complex demonstratives. We will show that a recent and particularly subtle syntactically based argument for the semantic/metaphysical status of complex demonstratives does not in fact show what semantic category complex demonstratives are..

In this paper, we offer a theory of the role of the nominal in complex demonstrative expressions, such as 'this dog' or 'that glove with a hole in it'.

Complex demonstratives, expressions of the form 'That F', 'These Fs', etc., have traditionally been taken to be referring terms. Yet they exhibit many of the features of quantified noun phrases. This has led some philosophers to suggest that demonstrative determiners are a special kind of quantifier, which can be paraphrased using a context sensitive definite description. Both these views contain elements of the truth, though each is mistaken. We advance a novel account of the semantic form of (...) class='Hi'>complex demonstratives that shows how to reconcile the view that they function like quantified noun phrases with the view that simple demonstratives function as context sensitive referring terms wherever they occur. If we are right, previous accounts of complex demonstratives have misconceived their semantic role; and philosophers relying on the majority view in employing complex demonstratives in analysis have proceeded on a false assumption.

This paper presents a number of objections to Jeffrey King's quantificational theory of complex demonstratives. Some of these objections have to do with modality, whereas others concern attitude ascriptions. Various possible replies are considered. The debate between quantificational theorists and direct reference theorists over complex demonstratives is compared with recent debates concerning definite descriptions.

There’s a long but relatively neglected tradition of attempting to explain why many researchers working on the nature of phenomenal consciousness think that it’s hard to explain.1 David Chalmers argues that this “meta-problem of consciousness” merits more attention than it has received. He also argues against several existing explanations of why we find consciousness hard to explain. Like Chalmers, we agree that the meta-problem is worthy of more attention. Contra Chalmers, however, we argue that there’s an existing explanation that is (...) more promising than his objections suggest. We argue that researchers find phenomenal consciousness hard to explain because phenomenal concepts are complex demonstratives that encode the impossibility of explaining consciousness as one of their application conditions.

A structured character is a semantic value of a certain sort. Like the more familiar Kaplanian characters, structured characters determine the contents of expressions in contexts. But unlike Kaplanian characters, structured characters also have constituent structures. The semantic theories with which most of us are acquainted do not mention structured characters. But I argue in this paper that these familiar semantic theories fail to make obvious distinctions in meaning---distinctions that can be made by a theory that uses structured characters. Thus (...) I conclude that we should reject these familiar semantic theories, and accept a semantic theory that includes structured characters among its semantic values. (shrink)

However, our case study will act as a cautionary note against any theory that attempts to derive important philosophical consequences from the shapes of sentences. (shrink)

In this paper I defend two claims regarding complex demonstratives. On the one hand I argue that, when one of these expressions misdescribes the referred object, the right semantic analysis is to treat the expression as uninterpretable. On the other, I claim that the uninterpretability thesis finds itself in trouble when it comes to dealing with non-deictic uses of complex demonstratives, i.e., uses of “that F” in which the speaker has no acquaintance or direct perception of any object (...) that could satisfy the predicative material. In order to make these two claims compatible, I set out to modify the way the uninterpretability thesis has been traditionally formulated. (shrink)

This paper argues for a different logical form for complex demonstratives, given that the quantificational account is correct. In itself that is controversial, but two aspects will be assumed. Firstly, there are arguments to believe that complex demonstratives have quantificational uses. Specifically, there are syntactic arguments. Secondly, a uniform semantics is preferable to a semantics of ambiguity. Given this, the proposed logical forms for complex demonstratives that are prevalent do not respect a fundamental property of quantifiers: permutation (...) invariance. The reason for this is the attempt to retain, in the logical forms proposed, the strong intuitions of reference that uses of complex demonstratives display. The paper suggests that the directly referential intuitions surrounding complex demonstratives cannot be taken to be part of the semantics of the expression. There appears to be no need to do so, either. The paper defends the new logical form against various objections. (shrink)

There is agreement neither concerning the point that is being made in Posterior analytics 96b15–25 nor the issue Aristotle intends to address. There are two major lines of interpretation of this passage. According to one, sketched by Themistius and developed by Philoponus and Eustratius, Aristotle is primarily concerned with determining the definitions of the infimae species that fall under a certain genus. They understand Aristotle as arguing that this requires collating definitional predictions, seeing which are common to which species. Pacius, (...) on the other hand, takes Aristotle to be saying that a genus is studied scientifically through first determining the infimae species that fall under that genus. This interpretation attributes to Aristotle a distinction between primary and derivative subjects. I argue for Pacius’s interpretation, defending it against Barnes’s objections.Author Keywords: Demonstration; Definition; Aristotle; Species; Principles. (shrink)

When analyzing complex longitudinal data, especially data from different educational settings, researchers generally focus only on the mean part (i.e., the regression coefficients), ignoring the equally important random part (i.e., the random effect variances) of the model. By using Project English Language and Literacy Acquisition (ELLA) data, we demonstrated the importance of taking the complex data structure into account by carefully specifying the random part of the model, showing that not only can it affect the variance estimates, the (...) standard errors, and the tests of significance of the regression coefficients, it also can offer different perspectives of the data, such as information related to the developmental process. We used xxM (Mehta, 2013), which can flexibly estimate different grade-level variances separately and the potential carryover effect from each grade factor to the later time measures. Implications of the findings and limitations of the study are discussed. (shrink)

Most philosophers recognize that applying the standard semantics for complex demonstratives to non-deictic instances results in truth conditions that are anomalous, at best. This fact has generated little concern, however, since most philosophers treat non-deictic demonstratives as marginal cases, and believe that they should be analyzed using a distinct semantic mechanism. In this paper, I argue that non-deictic demonstratives cannot be written off; they are widespread in English and foreign languages, and must be treated using the same semantic machinery (...) that is applied to deictic instances.

Grammatical metaphor in M. A. K. Halliday’s sense has long been extensively investigated by researchers in terms of theoretical and empirical studies. Regarding the empirical studies, they have predominantly employed observed or normalized frequencies of grammatical metaphor to uncover its distribution in different text types. Few studies, however, were conducted to quantitatively examine the complexity of grammatical metaphor in that no indicator presently is proposed to measure the degree of complexity in grammatical metaphor. This paper targeted at investigating the feasibility (...) of implementing entropy to measure this complexity. The findings demonstrate that the entropy value could be afforded as an indicator of complexity of grammatical metaphor to efficiently uncover the way that disciplines of different registers build knowledge by means of employing such linguistic features as grammatical metaphor. This research is significant in that it sheds light on the quantitative comparison of complexity of grammatical metaphor in text analysis. (shrink)

Our socio-economic innovation ecosystem is riddled with ever-increasing complexity, as we are faced with more frequent and intense shocks, such as COVID-19. Unfortunately, addressing complexity requires a different kind of economic governance. There is increasing pressure on economics to not only going beyond its traditional mainstream boundaries but also to tackle real-world problems such as fostering structural change, enhancing sustained growth, promoting inclusive development in the era of the digital economy, and boosting green growth, while addressing the divide between the (...) financial sector and the real economy. This book demonstrates how to apply complexity science to economics, in an effective and instructive way, in the interest of life-enhancing policies. The book revolves around the non-negligible problem of why economics, to date, seems to be insufficient in guiding economic governance to navigate through real and ever-intensifying complex socio-economic and environmental challenges. With its interdisciplinary approach, the book scans the nuanced nexus between complexity and economics by incorporating, as well as transcending the state-of-the-art literature. It identifies ways to trigger opportunities for behaviour change in the economic profession with respect to how to teach and what, introducing and developing further complexity economics thinking with the configuration of its main principles and outlining the silhouette of next-generation economic governance. The book deciphers recommendations both for economic theory, practice, and education and economic governance. It will be of interest to students, scholars, academics, think tank researchers and economic policy practitioners at the national and/or supranational level.

This paper presents a dual intention model (DIM) of demonstrations as actions to show the agentive nature of demonstrations. According to the DIM, demonstrations are complex actions that contain as components at least three elements: an abductive intention, a deictic intention, and a basic ostensive act of indication. This paper unpacks these three components and discusses their roles from the viewpoint of the philosophy of action and the philosophy of language. It also shows how the DIM applies in selected (...) practical examples and explains the merits of the model in the context of other views on demonstrations and demonstratives. (shrink)

Fractal patterns offer one way to represent the rough complexity of the natural world. Whilst they dominate many of our visual experiences in nature, little large-scale perceptual research has been done to explore how we respond aesthetically to these patterns. Previous research (Taylor et al., 2011) suggests that the fractal patterns with mid-range fractal dimensions have universal aesthetic appeal. Perceptual and aesthetic responses to visual complexity have been more varied with findings suggesting both linear (Forsythe et al., 2011) and curvilinear (...) (Berlyne, 1970) relationships. Individual differences have been found to account for many of the differences we see in aesthetic responses but some, such as culture, have received little attention within the fractal and complexity research fields. This 2-study paper aims to test preference responses to fractal dimension and visual complexity, using a large cohort (N=443) of participants from around the world to allow universality claims to be tested. It explores the extent to which age, culture and gender can predict our preferences for fractally complex patterns. Following exploratory analysis that found strong correlations between fractal dimension and visual complexity, a series of linear mixed-effect models were implemented to explore if each of the individual variables could predict preference. The first tested a linear complexity model (likelihood of selecting the more complex image from the pair of images) and the second a mid-range fractal dimension model (likelihood of selecting an image within mid-range). Results show that individual differences can reliably predict preferences for complexity across culture, gender and age. However, in fitting with current findings the mid-range models show greater consistency in preference not mediated by gender, age or culture. This paper supports the established theory that the mid-range fractal patterns appear to be a universal construct underlying preference but also highlights the fragility of universal claims by demonstrating individual differences in preference for the interrelated concept of visual complexity. This highlights a current stalemate in the field of empirical aesthetics. (shrink)

A universally acknowledged, core property of language is its complexity, at each level of structure – sounds, words, phrases, clauses, utterances, and higher levels of discourse. How does this complexity originate and develop in a language? We cannot fully answer this question from spoken languages, since they are all thousands of years old or descended from old languages. However, sign languages of deaf communities can arise at any time and provide empirical data for testing hypotheses related to the emergence of (...) language complexity. An added advantage of the signed modality is a direct correspondence between visible physical articulations and linguistic structures, providing a more transparent view of linguistic complexity and its emergence (Sandler 2012). These essential characteristics of sign languages allow us to address the issue of emerging complexity by documenting the use of the body for linguistic purposes. We look at three types of discourse relations of increasing complexity motivated by research on spoken languages – additive, symmetric and asymmetric (Mann and Thompson 1988; Sanders, Spooren, and Noordman 1992), Each relation type can connect units at two different levels: within propositions (simpler) and across propositions (more complex). We hypothesized that these relations provide a measure for charting the time course of emergence of complexity, from simplest to most complex, in a new sign language. We test this hypothesis on Israeli Sign Languages (ISL), a young language, some of whose earliest users are still available for recording. Taking advantage of the unique relation in sign languages between bodily articulations and linguistic form, we study fifteen ISL signers from three different generations, and demonstrate that the predictions indeed hold. We also find that younger signers tend to converge on more systematic marking of relations, that they use fewer articulators for a given linguistic function than older signers, and that the form of articulations becomes reduced, as the language matures. Mapping discourse relations to the bodily expression of linguistic components across age groups reveals how simpler, less constrained, and more gesture-like expressions, become language. (shrink)

We use a method suggested by Kolmogorov complexity to examine some relations between Kolmogorov complexity and noncomputability. In particular we show that the method consistently gives us more information than conventional ways of demonstrating noncomputability . Also, many sets which are awkward to embed into the halting problem are easily shown noncomputable. We also prove a gap-theorem for outputting consecutive integers and find, for a given length n, a statement of length n with maximal proof length.

Phrases like "That man" are called complex demonstrative phrases. They are usually considered to be directly referential in nature. There are many arguments to suggest that such phrases are not directly referential, but are quantificational. This work examines the philosophical debate over the semantic status of complex demonstratives at length, arriving at the conclusion that the quantificational view is right. A new logical form is also suggested for complex demonstratives.

There is a perennial philosophical dream of a certain natural order for the natural kinds. The name of this dream is ‘the hierarchy requirement’. According to this postulate, proper natural kinds form a taxonomy which is both unique and traditional. Here I demonstrate that complex scientific objects exist: objects which generate different systems of scientific classification, produce myriad legitimate alternatives amongst the nonetheless still natural kinds, and make the hierarchical dream impossible to realize, except at absurdly great cost. Philosophical (...) hopes for a certain order in nature cannot be fulfilled. Natural kinds crosscut one another, ubiquitously so, and this crosscutting spells the end of the hierarchical dream.

In a spirit of collegial support, this paper argues that Beckett and Hager’s theoretical justification and empirical exemplifications do not do full justice to the complexity of group or team learning. We firstly reaffirm our support for the theoretical argument Becket and Hager make, though expressing some reservations about Complexity Theory, to explain the taken-for-granted assumptions that learning by an individual is the paradigm case of learning and that context plays a minimal role in this process. Drawing on our joint (...) and separate work, we demonstrate that Becket and Hager’s argument is less radical than it may initially seem because it is predicated on: (i) cognitive-bounded rather than “distributed” or “extended” conception of mind; (ii) material rather than a “immaterial” conception of activity; and (iii) co-present rather than a “fractional” or “connective” conception of ontology. Despite making this critique, we conclude by making the case that we are adding further substance to Becket and Hager’s overarching argument and, in doing so, encouraging them to be more radical about how they conceptualise the complexity of learning.

The arbitrariness of a signal has long been seen as a theoretically important but difficult to pin down notion. In this article, we suggest there are at least two different notions of arbitrariness at play in philosophical and scientific debates concerning the use of arbitrary signals, and work towards improved analyses of both. We then consider how these different types of arbitrariness can co-occur and come apart. Finally, we examine the connections between these two types of arbitrariness and the cognitive (...) complexity of signal users with an eye towards better evaluating one possible form of human-nonhuman communicative continuity. We show that each type of arbitrariness bears its own nuanced relationship to cognitive complexity, demonstrating the theoretical importance of keeping these two notions separate. (shrink)
