I identify a number of problematic aspects of Christiansen & Chater's (C&C's) contribution. These include their suggestion that subjacency and binding reflect non-domain-specific mechanisms; that proto-language is a ; and that non-adaptationism requires overly rich innate structures, and is incompatible with acceptable evolutionary processes. It shows that a fully UG (Universal Grammar)-free version of the authors' neo-adaptationism would be incoherent.

How can abductive reasoning be physical, feasible, and reliable? This is Fodor’s riddle of abduction, and its apparent intractability is the cause of Fodor’s recent pessimism regarding the prospects for cognitive science. I argue that this riddle can be solved if we augment the computational theory of mind to allow for non-computational mental processes, such as those posited by classical associationists and contemporary connectionists. The resulting hybrid theory appeals to computational mechanisms to explain the semantic coherence of inference and associative (...) mechanisms to explain the efficient retrieval of relevant information from memory. The interaction of these mechanisms explains how abduction can be physical, feasible, and reliable. (shrink)

The connection between theories of truth and meaning is explored. Theories of truth and meaning are connected in a way such that differences in the conception of what it is for a sentence to be true are engendered by differences in the conception of how meanings depend on each other, and on a base of underlying facts. It is argued that this view is common ground between Davidson and Dummett, and that their dispute over realism is really a dispute in (...) the theory of meaning over holism and molecularism. The view offered is contrasted with influential pragmatist and modest views. (shrink)

I defend the non-cognitivist outlook on knowledge of grammar from the criticisms levelled against it by Jonathan Knowles. The first part of the paper is largely critical. First, I argue that Knowles's argument against Christopher Peacocke and Martin Davies's non-cognitivist account of the psychological reality of grammar fails, and thus that no reason has been given to think that cognitivism is integral to an understanding of Chomskyan theoretical linguistics. Second, I argue that cognitivism is philosophically problematic. In particular, I argue (...) (a) that Knowles misunderstands Stephen Stich and Gareth Evans's points about inferential integration; and (b) that Knowles misunderstands the philosophical status and demands of Evans's Generality Constraint. In the final, non-critical part of the paper, I try to show that the Stich and Evans's constraints, together with a Self-Knowledge Constraint, are genuine constitutive constraints by showing how they have rationality as their underlying organizing principle. I argue further that recognizing the constitutive character of these constraints allows one to distinguish two kinds of psychological explanation; in this sense, the constraints mark a genuine boundary in our theorizing about the mind.

Along with the increasing popularity of connectionist language models has come a number of provocative suggestions about the challenge these models present to Chomsky's arguments for nativism. The aim of this paper is to assess these claims. We begin by reconstructing Chomsky's argument from the poverty of the stimulus and arguing that it is best understood as three related arguments, with increasingly strong conclusions. Next, we provide a brief introduction to connectionism and give a quick survey of recent efforts to (...) develop networks that model various aspects of human linguistic behavior. Finally, we explore the implications of this research for Chomsky's arguments. Our claim is that the relation between connectionism and Chomsky's views on innate knowledge is more complicated than many have assumed, and that even if these models enjoy considerable success the threat they pose for linguistic nativism is small.

Two kinds of theoretical framework for syntax are encountered in current linguistics. One emerged from the mathematization of proof theory, and is referred to here as generative-enumerative syntax (GES). A less explored alternative stems from the semantic side of logic, and is here called model-theoretic syntax (MTS). I sketch the outlines of each, and give a capsule summary of some mathematical results pertaining to the latter. I then briefly survey some diverse types of evidence suggesting that in some ways MTS (...) seems better suited to theorizing about the relevant linguistic phenomena. (shrink)

Cappelen proposes a radically externalist framework for conceptual engineering. This approach embraces the following two theses. Firstly, the mechanisms that underlie conceptual engineering are inscrutable: they are too complex, unstable and non-systematic for us to grasp. Secondly, the process of conceptual engineering is largely beyond our control. One might think that these two theses are peculiar to the Austerity Framework, or to metasemantic externalism more generally. However, Cappelen argues that there is no reason to think that internalism avoids either commitment. (...) Cappelen argues that to do so she must provide arguments for 3 claims: there are inner states that are scrutable and within our control; concepts supervene on these inner states; and the determination relation from supervenience base to content is itself scrutable and within our control. In this paper, I argue that internalist conceptual role theories of content can meet Cappelen’s challenge. (shrink)

Two of the main theoretical approaches to the evolution of language are biolinguistics and usage-based approaches. Both are often conceptualized as belonging to seemingly irreconcilable ‘camps.’ Biolinguistic approaches assume that the ability to acquire language is based on a language-specific genetic foundation. Usage-based approaches, on the other hand, stress the importance of domain-general cognitive capacities, social cognition, and interaction. However, there have been a number of recent developments in both paradigms which suggest that biolinguistic and usage-based approaches are actually moving (...) closing together. For example, theoretical advancements such as evo-devo and complex adaptive systems theory have gained traction in the language sciences, leading to changed conceptions of issues like the relative influence of “nature” and “nurture.” In this paper, we outline points of convergence between current minimalist biolinguistic and usage-based approaches regarding four contentious issues: a) modularity and domain-specificity, b) innateness and development, c) cultural and biological evolution, d) knowledge of language and its description. We show that across both paradigms, researchers have come to increasingly embrace more complex views of these issues. They also have come to appreciate the view that biological and cultural evolution are closely intertwined, which leads to an increased amount of common ground between minimalist biolinguistics and usage-based approaches.

The meaning that expressions take on particular occasions often depends on the context in ways which seem to transcend its direct effect on context-sensitive parameters. ‘Truth-conditional pragmatics’ is the project of trying to model such semantic flexibility within a compositional truth-conditional framework. Most proposals proceed by radically ‘freeing up’ the compositional operations of language. I argue, however, that the resulting theories are too unconstrained, and predict flexibility in cases where it is not observed. These accounts fall into this position because (...) they rarely, if ever, take advantage of the rich information made available by lexical items. I hold, instead, that lexical items encode both extension and non-extension determining information. Under certain conditions, the non-extension determining information of an expression e can enter into the compositional processes that determine the meaning of more complex expressions which contain e. This paper presents and motivates a set of type-driven compositional operations that can access non-extension determining information and introduce bits of it into the meaning of complex expressions. The resulting multidimensional semantics has the tools to deal with key cases of semantic flexibility in appropriately constrained ways, making it a promising framework to pursue the project of truth-conditional pragmatics.

Often, the deepest disagreements are about starting points, and which considerations are relevant.

The meaning of 'most' can be described in many ways. We offer a framework for distinguishing semantic descriptions, interpreted as psychological hypotheses that go beyond claims about sentential truth conditions, and an experiment that tells against an attractive idea: 'most' is understood in terms of one-to-one correspondence. Adults evaluated 'Most of the dots are yellow', as true or false, on many trials in which yellow dots and blue dots were displayed for 200 ms. Displays manipulated the ease of using a (...) 'one-to-one with remainder' strategy, and a strategy of using the Approximate Number System to compare of (approximations of) cardinalities. Interpreting such data requires care in thinking about how meaning is related to verification. But the results suggest that 'most' is understood in terms of cardinality comparison, even when counting is impossible. (shrink)

Philosophy and Phenomenological Research, EarlyView.

Davidson conjectured that suitably formulated Tarski-style theories of truth can “do duty” as theories of meaning for the spoken languages that humans naturally acquire. But this conjecture faces a pair of old objections that are, in my view, fatal when combined. Foster noted that given any theory of the sort Davidson envisioned, for a language L, there will be many equally true theories whose theorems pair endlessly many sentences of L with very different specifications of whether or not those sentences (...) are true. And if L includes words ‘true’, then for reasons stressed by Tarski, it’s hard to see how any truth theory for L could be correct. Moreover, each of these concerns amplifies the other. Appealing to possible worlds will not help with Foster’s Problem, for reasons that Chomsky discussed in the 1950s, and appealing to trivalent models of truth will not avoid concerns illustrated with Liar Sentences.

I argue that linguistic meanings are instructions to build monadic concepts that lie between lexicalizable concepts and truth-evaluable judgments. In acquiring words, humans use concepts of various adicities to introduce concepts that can be fetched and systematically combined via certain conjunctive operations, which require monadic inputs. These concepts do not have Tarskian satisfaction conditions. But they provide bases for refinements and elaborations that can yield truth-evaluable judgments. Constructing mental sentences that are true or false requires cognitive work, not just an (...) exercise of basic linguistic capacities. (shrink)

: Jerry Fodor and Zenon Pylyshyn have proposed a purely referential-causal semantics, a semantics without meanings. Adopting Pylyshyn’s previous treatment of the fact that we can perceive and track something before we have any idea of what that is, these authors claim that such causal relations to external entities allow us to word-label them and thereby build an entire lexicon with specific referents. I disagree and explain why I do so. The kind of semantics that I prefer is radically opposite: (...) the one proposed by Noam Chomsky and Paul Pietroski. This is an internalist semantics that only has meanings, reference being indirect, often indefinite, sometimes problematic. Chomsky insists that the only posit that is tenable is the internal structure of the speaker-hearer, a complex, abstractly characterizable, computational-derivational apparatus, optimal if left alone, that interfaces with other cognitive apparatuses: the articulatory-perceptual one and the conceptual-intentional one, satisfying the constraints that they impose. I show that the semantics proposed by Fodor and Pylyshyn is especially problematic when inexistent entities, possible entities, fictional characters and objects in the remote past are examined. It is, however, problematic even when dealing with more ordinary concepts. On the contrary, an internalist semantics avoids all these problems. Keywords: Internalist Semantics; Theory of Meaning and Reference; Jerry A. Fodor; Noam Chomsky; Paul Pietroski Menti con significati Riassunto: Jerry Fodor e Zenon Pylyshyn hanno proposto una semantica interamente causale-referenziale, una semantica priva di qualsiasi nozione di significato. Adottando la precedente trattazione di Pylyshyn di come è possibile percepire e inseguire oggetti prima di avere alcuna idea di cosa essi siano, questi autori pretendono che queste interazioni causali con enti esterni bastano a etichettarli con dei termini lessicali, costruendo un intero lessico con referenti specifici, senza la componente del significato. Io dissento e spiego perché. Il tipo di semantica che adotto è diametralmente opposto, una semantica che ha solo significati, per la quale i referenti esterni sono indiretti, spesso non definiti, talvolta problematici. Noam Chomsky e Paul Pietroski hanno perfezionato questa semantica puramente internalista, insistendo che l’unico attributo sostenibile è la struttura mentale interna al locutore, una struttura complessa, caratterizzabile solo a un livello di astrazione adeguato, atta a soddisfare i vincoli imposti dai sistemi cognitivi con i quali interagisce: quello articolatorio-percettivo e quello concettuale-intenzionale. Mostro che la semantica proposta da Fodor e Pylyshyn si scontra con problemi insolubili quando tratta enti inesistenti, enti possibili, invenzioni letterarie e oggetti appartenenti a un passato remoto. In effetti, si scontra con problemi insolubili anche quando tratta oggetti e proprietà ordinari. Una semantica interamente internalista non incontra nessuno di questi problemi.

How do we know what other speakers say? Perhaps the most natural view is that we hear a speaker's utterance and infer what was said, drawing on our competence in the syntax and semantics of the language. An alternative view that has emerged in the literature is that native speakers have a non-inferential capacity to perceive the content of speech. Call this the perceptual view. The disagreement here is best understood as an epistemological one about whether our knowledge of what (...) speakers say is epistemically mediated by our linguistic competence. The present paper takes up the question of how we should go about settling this issue. Arguments for the perceptual view generally appeal to the phenomenology of speech comprehension. The present paper develops a line of argument for the perceptual view that draws on evidence from empirical psychology. The evidence suggests that a speaker's core syntactic and semantic competence is typically deployed sub-personally. The point is not just that the competence is tacit or unconscious, but that the person is not the locus of the competence. I argue that standing competence can enter into the grounds for knowledge only if it is subject to a certain sort of epistemic assessment, an assessment that is appropriate only if the person is the locus of that competence. If the person is not the locus of a speaker's core linguistic competence, as the psychological evidence suggests, then that competence does not enter into the grounds for our knowledge of what speakers say. If this line of argument is right, it has implications for the epistemology of perception and for our understanding of how empirical psychology bears on epistemology generally. (shrink)

According to the approach developed by Thomas A. Sebeok (1921–2001) and his ‘global semiotics,’ semiosis and life converge. This leads to his cardinal axiom: ‘semiosis is the criterial attribute of life.’ His global approach to sign life presupposes his critique of anthropocentrism and glottocentrism. Global semiotics is open to zoosemiotics, indeed, even more broadly, biosemiotics which extends its gaze to semiosis in the whole living universe to include the realms of macro- and microorganisms. In Sebeok’s conception, the sign science is (...) not only the study of communication in culture, but of communicative behaviour from a biosemiotic perspective. (shrink)

In the present study, using event-related functional magnetic resonance imaging, we investigated a group of participants on a grammaticality classification task after they had been exposed to well-formed consonant strings generated from an artificial regular grammar. We used an implicit acquisition paradigm in which the participants were exposed to positive examples. The objective of this studywas to investigate whether brain regions related to language processing overlap with the brain regions activated by the grammaticality classification task used in the present study. (...) Recent meta-analyses of functional neuroimaging studies indicate that syntactic processing is related to the left inferior frontal gyrus (Brodmann's areas 44 and 45) or Broca's region. In the present study, we observed that artificial grammaticality violations activated Broca's region in all participants. This observation lends some support to the suggestions that artificial grammar learning represents a model for investigating aspects of language learning in infants [TICS 4 (2000) 178] and adults [Proceedings of the National Academy of Sciences of United States of America 99 (2002) 529].

The emperor's new mind (hereafter Emperor) is an attempt to put forward a scientific alternative to the viewpoint of according to which mental activity is merely the acting out of some algorithmic procedure. John Searle and other thinkers have likewise argued that mere calculation does not, of itself, evoke conscious mental attributes, such as understanding or intentionality, but they are still prepared to accept the action the brain, like that of any other physical object, could in principle be simulated by (...) a computer. In Emperor I go further than this and suggest that the outward manifestations ofconscious mental activity cannot even be properly simulated by calculation. To support this view, I use various arguments to show that the results of mathematical insight, in particular, do not seem to be obtained algorithmically. The main thrust ofthis work, however, is to present an overview ofthe present state of physical understanding and to show that an important gap exists at the point where, quantum and classical physics meet, as well as to speculate on how the conscious brain might be taking advantage ofwhatever new physics is needed to fill this gap to achieve its nonalgorithmic effects.

It is often thought that the computational paradigm provides a supporting case for the theoretical autonomy of the science of mind. However, I argue that computation is in fact incompatible with this alleged aspect of intentional explanation, and hence the foundational assumptions of orthodox cognitive science are mutually unstable. The most plausible way to relieve these foundational tensions is to relinquish the idea that the psychological level enjoys some special form of theoretical sovereignty. So, in contrast to well known antireductionist (...) views based on multiple realizability, I argue that the primary goal of a computational approach to the mind should be to facilitate a translation of the psychological to the neurophysiological.

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account attributes this deficit to an impairment in syntactic representations, whereas others propose that the underlying structural representations are unimpaired, but sentence comprehension is affected by processing deficits, such as slow lexical activation, reduction in memory resources, slowed processing and/or intermittent deficiency, among others. We test the claims of two processing accounts, slowed processing and intermittent deficiency, (...) and two versions of the Trace Deletion Hypothesis, in a computational framework for sentence processing implemented in ACT-R. The assumption of slowed processing is operationalized as slow procedural memory, so that each processing action is performed slower than normal, and intermittent deficiency as extra noise in the procedural memory, so that the parsing steps are more noisy than normal. We operationalize the TDH as an absence of trace information in the parse tree. To test the predictions of the models implementing these theories, we use the data from a German sentence—picture matching study reported in Hanne, Sekerina, Vasishth, Burchert, and De Bleser. The data consist of offline and online measures. From among the models considered, the model assuming that both slowed processing and intermittent deficiency are present emerges as the best model of sentence processing difficulty in aphasia. The modeling of individual differences suggests that, if we assume that patients have both slowed processing and intermittent deficiency, they have them in differing degrees. (shrink)

The article reconstructs the main lines of three hypotheses in the current literature concerning the evolutionary pace which characterized the natural history of human language: the “continuist” and gradualist perspective, the “discontinuist” and evolution-free perspective, and the “punctuationist” view. This current debate appears to have a long history, which starts at least from Darwin’s time. The article highlights the similarities between the old and the modern debates in terms of history of ideas, and it shows the current limits of each (...) of these perspectives. In the final part, we present an alternative approach which considers human language not as a single trait, but as the result of a mosaic of different elements, some of which recently evolved, and some others gradually evolved and phylogenetically ancient. When matched with a tree thinking and comparative perspective, this view suggests that expressions of symbolic and linguistic behaviors in other human species could have preceded the more complex and systematic behaviors showed by Homo sapiens.

The externalist examples of Burge, Putnam etc. were offered as examples of how it is physically identical twins can differ in mental states such as belief, and little attention was paid to the interpretations the twins impose on their respective acoustic inputs. The received story today is that this form of interpretation—the semantic reading one assigns the sounds one hears—is the product of inference. The problem for this inferential model is simple to state: though the twins are physical doppelgangers and (...) don't differ in their acoustic inputs, they differ in the interpretations they impose on their respective inputs. I argue that the inferential model does not allow for how it is the twins arrive at these different interpretations. And, since the externalist examples are compelling, this tells against the inferential model. (shrink)

The range of hypotheses considered is surprising in that the most arguably plausible one is not included: the invariant principles of language are available for life, while the parameters of variation cannot be set after puberty. This hypothesis provides a better explanation than the author's for both the deep similarities and the vast differences between child “language growth” and adult language acquisition.

Frankfurt-Style Cases (FSCs) seem to elicit the intuitive judgment that an agent is morally responsible despite being unable to act otherwise, which is supposed to falsify the Principle of Alternative Possibility (PAP). Recent empirical studies have shown that the inclination toward this intuitive judgment is shared among people, which seems to reinforce the argument against the PAP. However, some scholars have argued for Descriptive Anti-Intuitionism (DAI) — intuitive judgments have never played an evidential role in philosophy — and thus denied (...) the philosophical significance of such empirical findings. I point out that although DAI fails in its literal claim for FSCs, an associated insight remains potent: an intuitive judgment is so fragile that it can be easily defeated by further arguments. Nevertheless, I argue, empirical studies are significant in uncovering the general principles to which we are committed in our practice concerning moral responsibility. I clarify how such findings can play a robust evidential role in philosophical debates concerning moral responsibility by tracing the literature written by Frankfurt and philosophers. (shrink)

Epstein et al.'s theory of SLA is heavily dependent on assumptions about both the nature of the acquisition device and the grammar that it produces. This commentary briefly explores the consequences of an alternative set of assumptions, focusing on the possibility that the acquisition device does not include UG and that syntactic representations do not contain functional projections.

This discussion article addresses the assumption formulated in Dan Everett's new book Language: The Cultural Tool that language is not only an instrument for communication, but also an instrument for thought. It argues that the latter assumption is far from obvious, and that, in any case, one cannot put communication and thought on a par in discussing the functionality of language.

Recent research suggests that language evolution is a process of cultural change, in which linguistic structures are shaped through repeated cycles of learning and use by domain-general mechanisms. This paper draws out the implications of this viewpoint for understanding the problem of language acquisition, which is cast in a new, and much more tractable, form. In essence, the child faces a problem of induction, where the objective is to coordinate with others (C-induction), rather than to model the structure of the (...) natural world (N-induction). We argue that, of the two, C-induction is dramatically easier. More broadly, we argue that understanding the acquisition of any cultural form, whether linguistic or otherwise, during development, requires considering the corresponding question of how that cultural form arose through processes of cultural evolution. This perspective helps resolve the “logical” problem of language acquisition and has far-reaching implications for evolutionary psychology. (shrink)
