: 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.

This book dares to challenge natural selection--not in the name of religion but in the name of good science. Most scientists are so terrified of religious attacks on the theory of evolution that it is never examined critically. There are significant scientific and philosophical problems with the theory of natural selection. Darwin claimed the factors that determine the course of evolution are very largely environmental. Empirical results in biology are increasingly calling this thesis into question. The authors show that Darwinism (...) is committed to inferring, from the premise that a kind of creature with a certain trait was selected, the conclusion that that kind of creature was selected for having that trait. Though such inferences are fallacious, they are nevertheless unavoidable within the Darwinist framework. Ultimately, Jerry Fodor and Massimo Piattelli-Palmarini level a devastating critique against Darwinist orthodoxy and suggest new ways of thinking about evolution.--From publisher description.

Most biologists and some cognitive scientists have independently reached the conclusion that there is no such thing as learning in the traditional “instructive‘ sense. This is, admittedly, a somewhat extreme thesis, but I defend it herein the light of data and theories jointly extracted from biology, especially from evolutionary theory and immunology, and from modern generative grammar. I also point out that the general demise of learning is uncontroversial in the biological sciences, while a similar consensus has not yet been (...) reached in psychology and in linguistics at large. Since many arguments presently offered in defense of learning and in defense of “general intelligence‘ are often based on a distorted picture of human biological evolution, I devote some sections of this paper to a critique of “adaptationism,‘ providing also a sketch of a better evolutionary theory. Moreover, since certain standard arguments presented today as “knock-down‘ in psychology, in linguistics and in artificial intelligence are a perfect replica of those once voiced by biologists in favor of instruction and against selection, I capitalize on these errors of the past to draw some lessons for the present and for the future.

"Fascinating and insightful.... I cannot recall a book that has made me think more about the nature of thinking." -- Richard C. Lewontin Harvard University Everyone knows that optical illusions trick us because of the way we see. Now scientists have discovered that cognitive illusions, a set of biases deeply embedded in the human mind, can actually distort the way we think. In Inevitable Illusions, distinguished cognitive researcher Massimo Piattelli-Palmarini takes us on a provocative, challenging, and thoroughly entertaining (...) exploration of the games our minds play. He opens the doors onto the newly charted realm of the cognitive unconscious to reveal the full range of illusions, showing how they inhibit our ability to reason--no matter what our educational background or IQ. Inevitable Illusions is stimulating, eye-opening food for thought. (shrink)

While the search for the neural basis of the language of thought is a laudable enterprise, and the article by Hurford a valiant first attempt, we argue that in investigating the argument structure of natural language it will ultimately prove more fruitful to consider the restrictions forced on the system by its inherently syntactic character.

Christiansen & Chater ignore the many linguistic universals that cannot be reduced to processing or cognitive constraints, some of which we present. Their claim that grammar is merely acquired language processing skill cannot account for such universals. Their claim that all other universal properties are historically and culturally based is a nonsequitur about language evolution, lacking data.

Why Jerry Fodor and Massimo Piattelli-Palmarini are wrong about Darwin and evolution.

Three types of problems are raised in this commentary: On the linguistic side, we emphasize the importance of an appropriate definition of the different domains of linguistics. This is needed to define the domains (lexicon-syntax-semantics) to which transformational relations apply. We then question the concept of Broca's aphasia as a “functional” syndrome, associated with a specific lesion. Finally, we discuss evidence from functional brain imaging. The breadth and potential impact of such evidence has grown considerably in the last few years, (...) expanding our knowledge of the multiple contributions of the “Broca's region” to phonological, lexical-semantic, and syntactic processing. “Lumping” under diagnostic labels, such as Broca's aphasia, should be replaced by more detailed linguistic and neurological descriptions of the clinical cases.

In their book What Darwin Got Wrong, Jerry Fodor and Massimo Piattelli-Palmarini construct an a priori philosophical argument and an empirical biological argument. The biological argument aims to show that natural selection is much less important in the evolutionary process than many biologists maintain. The a priori argument begins with the claim that there cannot be selection for one but not the other of two traits that are perfectly correlated in a population; it concludes that there cannot (...) be an evolutionary theory of adaptation. This article focuses mainly on the a priori argument. (shrink)

What Jerry Fodor and Massimo Piattelli-Palmarini got wrong about Darwin and evolution.

Bloom masterfully captures the state-of-the-art in the study of lexical acquisition. He also exposes the extent of our ignorance about the learning of names for non-observables. HCLMW adopts an innatist position without adopting modularity of mind; however, it seems likely that modularity is needed to bridge the gap between object names and the rest of the lexicon.

Hume? Yes, David Hume, that's who Jerry Fodor looks to for help in advancing our understanding of the mind. Fodor claims his Treatise of Human Nature as the foundational document of cognitive science: it launched the project of constructing an empirical psychology on the basis of a representational theory of mind. Going back to this work after more than 250 years we find that Hume is remarkably perceptive about the components and structure that a theory of mind requires. Careful (...) study of the Treatise helps us to see what's amiss with much twentieth-century philosophy of mind, and to get on the right track. Hume says in the Treatise that his main project is to construct a theory of human nature and, in particular, a theory of the mind. Hume Variations examines his account of cognition and how it is grounded in his 'theory of ideas'. Fodor discusses such key topics as the distinction between 'simple' and 'complex' ideas, the thesis that an idea is some kind of picture, and the roles that 'association' and 'imagination' play in cognitive processes. He argues that the theory of ideas, as Hume develops it, is both historically and ideologically continuous with the representational theory of mind as it is now widely endorsed by cognitive scientists. This view of Hume is explicitly opposed to recent discussions by critics who hold that the theory of ideas is the Achilles heel of his philosophy and that he would surely have abandoned it if only he had read Wittgenstein carefully.You don't have to know much about Hume to enjoy this inventively argued, provocative, and stimulating defence of the representational theory of mind--which is looking increasingly hard to resist.LINES OF THOUGHTPhilosophy books don't need to be hundreds of pages long to make a substantial contribution to the subject.

Christiansen & Chater (C&C) have taken the interactionist approach to linguistic universals to an extreme, adopting the metaphor of language as an organism. This metaphor adds no insights to five decades of analyzing language universals as the result of interaction of linguistically unique and general cognitive systems. This metaphor is also based on an outmoded view of classical Darwinian evolution and has no clear basis in biology or cognition.

Jerry Fodor and Ernie Lepore have produced a series of original and controversial essays on issues relating to compositionality in language and mind; they have now revised them all for publication together in this volume. Compositionality is the following aspect of a system of representation: the complex symbols in the system inherit their syntactic and semantic properties from the primitive symbols of the system. Fodor and Lepore argue that compositionality determines what view we must take of the nature of (...) concepts. Anyone trying to figure out how language and mind work must take account of this challenging work by two leading figures in the field. (shrink)

This study synthesizes current information from the various fields of cognitive science in support of a new and exciting theory of mind. Most psychologists study horizontal processes like memory and information flow; Fodor postulates a vertical and modular psychological organization underlying biologically coherent behaviors. This view of mental architecture is consistent with the historical tradition of faculty psychology while integrating a computational approach to mental processes. One of the most notable aspects of Fodor's work is that it articulates features not (...) only of speculative cognitive architectures but also of current research in artificial intelligence.

The renowned philosopher Jerry Fodor, a leading figure in the study of the mind for more than twenty years, presents a strikingly original theory on the basic constituents of thought. He suggests that the heart of cognitive science is its theory of concepts, and that cognitive scientists have gone badly wrong in many areas because their assumptions about concepts have been mistaken. Fodor argues compellingly for an atomistic theory of concepts, deals out witty and pugnacious demolitions of rival theories, (...) and suggests that future work on human cognition should build upon new foundations. This lively, conversational, and superbly accessible book is the first volume in the Oxford Cognitive Science Series, where the best original work in this field will be presented to a broad readership. Concepts will fascinate anyone interested in contemporary work on mind and language. Cognitive science will never be the same again. (shrink)

Several arguments for combinatorial structure in mental representations are then reviewed. These include arguments based on the ‘systematicity’ of mental representation: i.e., on the fact that cognitive capacities always exhibit certain symmetries, so that the ability to entertain a given thought implies the ability to entertain thoughts with semantically related contents. We claim that such arguments make a powerful case that mind/brain architecture is not Connectionist at the cognitive level. We then consider the possibility that Connectionism may provide an account of the neural (or ‘abstract neurological’) structures in which Classical cognitive architecture is implemented.

The paper explores the distinction between two doctrines, both of which inform theory construction in much of modern cognitive psychology: the representational theory of mind and the computational theory of mind. According to the former, propositional attitudes are to be construed as relations that organisms bear to mental representations. According to the latter, mental processes have access only to formal (nonsemantic) properties of the mental representations over which they are defined.The following claims are defended: (1) That the traditional dispute between (...) “rational” and “naturalistic” psychology is plausibly viewed as an argument about the status of the computational theory of mind. Rational psychologists accept a formality condition on the specification of mental processes; naturalists do not. (2) That to accept the formality condition is to endorse a version of methodological solipsism. (3) That the acceptance of some such condition is warranted, at least for that part of psychology which concerns itself with theories of the mental causation of behavior. This is because: (4) such theories require nontransparent taxonomies of mental states; and (5) nontransparent taxonomies individuate mental states without reference to their semantic properties. Equivalently, (6) nontransparent taxonomies respect the way that the organism represents the object of its propositional attitudes toitself, and it is this representation which functions in the causation of behavior.The final section of the paper considers the prospect for a naturalistic psychology: one which defines its generalizations over relations between mental representations and their environmental causes, thus seeking to account for the semantic properties of propositional attitudes. Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)

Jerry Fodor presents a new development of his famous Language of Thought hypothesis, which has since the 1970s been at the centre of interdisciplinary debate about how the mind works. Fodor defends and extends the groundbreaking idea that thinking is couched in a symbolic system realized in the brain. This idea is central to the representational theory of mind which Fodor has established as a key reference point in modern philosophy, psychology, and cognitive science. The foundation stone of our (...) present cognitive science is Turing's suggestion that cognitive processes are not associations but computations; and computation requires a language of thought. So the latest on the Language of Thought hypothesis, from its progenitor, promises to be a landmark in the study of the mind. LOT 2 offers a more cogent presentation and a fuller explication of Fodor 's distinctive account of the mind, with various intriguing new features. The central role of compositionality in the representational theory of mind is revealed: most of what we know about concepts follows from the compositionality of thoughts. Fodor shows the necessity of a referentialist account of the content of intentional states, and of an atomistic account of the individuation of concepts. Not least among the new developments is Fodor 's identification and persecution of pragmatism as the leading source of error in the study of the mind today. LOT 2 sees Fodor advance undaunted towards the ultimate goal of a theory of the cognitive mind, and in particular a theory of the intentionality of cognition. No one who works on the mind can ignore Fodor 's views, expressed in the coruscating and provocative style which has delighted and disconcerted countless readers over the years. (shrink)

This book is largely a reconsideration of the arguments that are supposed to ground this consensus.

Written in a highly readable, irreverent style, The Elm and the Expert provides a lively discussion of semantic issues about mental representation, with special attention to issues raised by Frege's problem, Twin cases, and the putative indeterminacy of reference. Bound to be widely read and much discussed, The Elm and the Expert, written in Jerry Fodor's usual highly readable, irreverent style, provides a lively discussion of semantic issues about mental representation, with special attention to issues raised by Frege's problem, (...) Twin cases, and the putative indeterminacy of reference. The book extends and revises a view of the relation between mind and meaning that the author has been developing since his 1975 book, The Language of Thought. There is a general consensus among philosophers that a referential semantics for mental representation cannot support a robust account of intentional explanation. Fodor has himself espoused this view in previous publications, and it is widespread (if tacit) throughout the cognitive science community. This book is largely a reconsideration of the arguments that are supposed to ground this consensus. Fodor concludes that these considerations are far less decisive than has been supposed. He offers a theory sketch in which psychological explanation is intentional, psychological processes are computational, and the semantic properties of mental representations are referential. Connections with the problem of "naturalizing" intentionality are also explored. The four lectures in The Elm and the Expert were originally delivered in Paris in the spring of 1993 to inaugurate the Jean Nicod Lecture series. The Jean Nicod Lectures are delivered annually by a leading philosopher of mind or philosophically oriented cognitive scientist. The 1993 lectures marked the centenary of the birth of the French philosopher and logician Jean Nicod (1893-1931). The lectures are sponsored by the Centre National de la Recherche Scientifique (CNRS) as part of its effort to develop the interdisciplinary field of cognitive science in France. Jean Nicod series.

The Modularity of Mind proposes an alternative to the or view of cognitive architecture that has dominated several decades of cognitive science. Whereas interactionism stresses the continuity of perceptual and cognitive processes, modularity theory argues for their distinctness. It is argued, in particular, that the apparent plausibility of New Look theorizing derives from the failure to distinguish between the (correct) claim that perceptual processes are inferential and the (dubious) claim that they are unencapsidated, that is, that they are arbitrarily sensitive (...) to the organism's beliefs and desires. In fact, according to modularity theory, perceptual processes are computationally isolated from much of the background knowledge to which cognitive processes have access. The postulation of autonomous, domain-specific psychological mechanisms underlying perceptual integration connects modularity theory with the tradition of faculty psychology, in particular, with the work of Franz Joseph Call. Some of these historical affinities, and some of the relations between faculty psychology and Cartesianism, are discussed in the book. (shrink)
