I present the symbol grounding problem in the larger context of a materialist theory of content and then present two problems for causal, teleo-functional accounts of content. This leads to a distinction between two kinds of mental representations: presentations and symbols; only the latter are cognitive. Based on Milner and Goodale’s dual route model of vision, I posit the existence of precise interfaces between cognitive systems that are activated during object recognition. Interfaces are constructed as a child learns, and is (...) taught, how to interact with its environment; hence, interface structure has a social determinant essential for symbol grounding. Symbols are encoded in the brain to exploit these interfaces, by having projections to the interfaces that are activated by what they symbolise. I conclude by situating my proposal in the context of Harnad’s (1990) solution to the symbol grounding problem and responding to three standard objections. (shrink)

Jerry Fodor's argument for an innate language of thought continues to be a hurdle for researchers arguing that natural languages provide us with richer conceptual systems than our innate cognitive resources. I argue that because the logical/formal terms of natural languages are given a usetheory of meaning, unlike predicates, logical/formal terms might be learned without a mediating internal representation. In that case, our innate representational system might have less logical structure than a natural language, making it possible that we augment (...) our innate representational system and improve our ability to think by learning a natural language.

I demonstrate that locking on, a key notion in Jerry Fodor's most recent theory of content, supplemented informational atomism (SIA), is cashed out in terms of asymmetric dependence, the central notion in his earlier theory of content. I use this result to argue that SIA is incompatible with the language of thought hypothesis because the constraints on the causal relations into which symbols can enter imposed by the theory of content preclude the causal relations needed between symbols for them to (...) serve as the elements of the medium of thought.

Barsalou's elision of the personal and sub-personal levels tends to conceal the fact that he is, at best, providing the “specs” but not yet a model for his hypothesized perceptual symbols.

I consider how several results from cognitive science bear on the nature of representation and how representations might be structured. Distinguishing two notions of representation, presentations, which are cases of direct sensing, and symbols, which stand in for something else, I argue that only symbols pose a philosophical problem for naturalizing content. What is required is an account of how one thing can stand in for another. Milner and Goodale’s dual route model of vision offers a model for this ‘stand-in’ (...) relation. Following this model, symbols must play a functional role of activating cognitive operations relevant to what the symbols stand in for. What emerges is an interconnected network of symbols whose tokenings are central – as opposed to modular – cognitive operations. A consequence of this view, which I call an acquired language of thought (ALOT) since most of the symbols humans use are the words of a natural language, is that the framework for central cognition is constructed during the acquisition of a natural language lexicon.Presentations and Symbols: What Cognition Requires of Representationalism.

Palmer=s main intuition pump, the Acolor machine, @ greatly underestimates the complexity of a system isomorphic in color experience to humans. The neuroscientific picture of this complexity makes clear that the brain actively produces our experiences by processes that science can investigate, thereby supporting functionalism and leaving no (color) room for a passive observer to witness subisomorphic experiential differences.

We offer a novel argument for one-boxing in Newcomb’s Problem. The intentional states of a rational person are psychologically coherent across time, and rational decisions are made against this backdrop. We compare this coherence constraint with a golf swing, which to be effective must include a follow-through after the ball is in flight. Decisions, like golf swings, are extended processes, and their coherence with other psychological states of a player in the Newcomb scenario links her choice with the way she (...) is predicted in a common cause structure. As a result, the standard argument for two-boxing is mistaken. (shrink)

We focus on Folieism, Rey's brand of Eliminativism about languages, according to which words, sentences, phonemes, and such, and consequently languages, do not exist; they are intentional inexistents, on a par with unicorns that speakers, under an ineluctable illusion, mistake as real. We present a simplified reconstruction of his argument, challenge what we take to be its presuppositions, and argue that its conclusion has unwanted social/ethical consequences and construes linguistics writ large in a strange light, as a kind of pretense, (...) leading us to reject Folieism.

In "The pitfalls of heritability," a review of Edward O. Wilson’s Consilience Times Literary Supplement, Feb 12, 1999, p33], Jerry Hirsch claims to have convicted Wilson of a "confusion about genetic similarity and difference." In his book, Wilson claims that if we assume that "a mere one thousand genes out of the fifty to a hundred thousand genes in the human genome were to exist in two forms in the population," the probability of any two humans--excluding identical siblings--having the same (...) genotype is vanishingly small. Hirsch points out that a single genotype can be produced in more than one way, thus increasing the likelihood of a single genotype recurring in the human population. Hirsch’s point is fair enough as far it goes, but it does not go nearly far enough. Hirsch has failed to carry out all the relevant calculations needed to determine the probability of two humans having the same genotype. In the realm of Vast numbers ("Very much greater than ASTronomical"--Dennett, 1995, p109), increased likelihood in and of itself tells us nothing. Here, then, are some of the relevant calculations.

I met Ernie in 1965 on the wrestling mats of our high school in North Bergen, New Jersey, a township on top of the plateau overlooking Hoboken and across the Hudson River from Manhattan. Hoboken then was still the Hoboken of Elia Kazan’s “On the Waterfront” (1954).1 Even though the Hudson was less than a mile across at that point, it was a wide spiritual divide. We were Jersey boys, not New Yorkers. Ernie was as ambitious as I was about (...) wrestling, and, so, after the season was over, we used to take a bus to Journal Square in Jersey City, and then walk about eight city blocks to a gym to lift weights. In those days, high schools didn’t have weight rooms; and gyms were scarce, men only, quite filthy, and entirely devoid of cardio equipment and Nautilus machines. They were all sweat, grunts, groans, and clanking iron. By 1968, on Tuesdays and Thursdays, after a grueling wrestling practice at the high school, we would take a bus to New York City (it took about a half hour to get into “the City” by bus, less if the Lincoln Tunnel was not crowded), and then a short subway ride up to the New York Athletic Club on 59th street, across from Central Park, to spend a couple of hours working out with former university wrestling stars—guys in their mid-twenties from places like Oklahoma, Nebraska, and Iowa—who were training to make the Olympic team. Even with all of this wrestling time, we were frustrated by the fact that there was nowhere to work out on Sundays. We investigated and found out that the Jersey City YMCA had a wrestling mat and was open on Sundays. We then spent our Sunday afternoons working out there, so as not to miss a day of wrestling. Wrestling was our savior: a healthy way to get out anger.2 But it wasn’t all wrestling. We did something else too: We talked. We spent many hours together introspecting out loud, and just trying to make sense of things. Ernie has mentioned in print one early topic of discussion: “We spent years trying to solve various logical conundra like how on earth the Virgin Mary could have been a virgin.... (shrink)

This volume contains fourteen essays discussing recent issues in the philosophy of language and the philosophy of mind. The collection is arranged into three sections: one on language, one on the intersection of language and mind, and a final section on mind. The topics include the context-sensitivity of semantics, anaphora, proper names, the nature of understanding, folk psychology and the Theory of Mind, self-awareness, the structure of the human mind and the extent to which it is modular, among others.

In an age where issues like climate change and the unintended consequences of technological innovation are high on the ethical and political agenda, questions about the nature and extent of our responsibilities to future generations have never been more important, yet simultaneously so difficult to answer. This book takes a unique approach to the problem by drawing on diverse traditions of thinking about care (including developmental psychology, phenomenology and feminist ethics) to explore the nature and meaning of our relationship with (...) the future. Demonstrating that many influential perspectives on intergenerational ethics, including positions advanced by John Rawls, Brian Barry, and Ulrich Beck are undermined by problems relating to uncertainty, it shows that an approach based on care ethics can confront the uncertain future successfully and give a viable account of the nature and scope of future-oriented responsibilities.

The Realm of Reason develops a new, general theory of what it is for a thinker to be entitled to form a given belief. The theory locates entitlement in the nexus of relations between truth, content, and understanding. Peacocke formulates three principles of rationalism that articulate this conception. The principles imply that all entitlement has a component that is justificationally independent of experience. The resulting position is thus a form of rationalism, generalized to all kinds of content.To show how these (...) principles are realized in specific domains, Peacocke applies the theory in detail to several classical problems of philosophy, including the nature of perceptual entitlement, induction, and the status of moral thought. These discussions involve an elaboration of the structure of entitlement in ways that have applications in many other areas of philosophy. He also relates the theory to classical and recent rationalist thought, and to current issues in the theory of meaning, reference and explanation. In the course of these discussions, he proposes a general theory of the a priori.The focus of the work lies in the intersection of epistemology, metaphysics, and the theory of meaning, and will be of interest both to students and researchers in these areas, and to anyone concerned with the idea of rationality.

Discovering high-utility itemsets (HUIs) consists of finding sets of items that yield a high profit in customer transaction databases. An important limitation of traditional high-utility itemset mining (HUIM) is that only the utility measure is used for assessing the interestingness of patterns. This leads to finding several itemsets that have a high profit but contain items that are weakly correlated. To address this issue, this paper proposes to integrate the concept of correlation in HUIM to find profitable itemsets that are (...) highly correlated, using the all-confidence and bond measures. An efficient algorithm named FCHM (fast correlated high-utility itemset miner) is proposed to efficiently discover correlated high-utility itemsets (CHIs). Two versions of the algorithm are proposed: FCHM|$_{all\text{-}confidence}$| and FCHM|$_{bond}$|⁠, which are based on the all-confidence and bond measures, respectively. An experimental evaluation was done using four real-life benchmark datasets from the HUIM literature: mushroom, retail, kosarak and foodmart. Results show that FCHM is efficient and can prune a huge amount of weakly CHIs. (shrink)

Suppose we believe that God created the world. Then surely we want it to be the case that he intended, in some sense at least, to create THIS world. Moreover, most theists want to hold that God didn't just guess or hope that the world would take one course or another; rather, he KNEW precisely what was going to take place in the world he planned to create. In particular, of each person P, God knew that P was to exist. (...) Call this the "standard" conception. Most theists find the standard conception appealing. Unfortunately, the view seems to conflict with the equally appealing idea — call it "temporal actualism" — that there are no "future" individuals beyond those that already exist in the present moment. For, on this view, for any historical person P, prior to creation, there was no such person as P and hence nothing about P for God to know. Hence, in particular, God couldn't have known that P was to exist. This is of course not a new problem. But past solutions to it are highly problematic. In this paper, after canvassing previous approaches, I will propose a solution that seems to preserve both temporal actualism and a suitably robust form of the standard conception while avoiding the pitfalls of the past.

In February 54b.c. Cicero concludes a missive to his brother with a passing and – for us – tantalizing remark:Lucreti poemata ut scribis ita sunt, multis luminibus ingeni, multae tamen artis. sed cum veneris. virum te putabo si Sallusti Empedoclea legeris; hominem non putabo. Quintus had, it seems, readDe rerum natura, or at least parts thereof, just before he left Rome for an undisclosed location nearby, and he shared his enthusiasm with his brotherper codicillos. Meanwhile, he was corresponding with Julius (...) Caesar, whose staff in Gaul he was about to join. When, a few months later, he was stationed with Caesar, he was involved in another literary affair, this time concerning his brother who wrote to him, inquiring about his autobiographicalDe temporibus suis:quo modo nam, mi frater, de nostris versibus Caesar? nam primum librum se legisse scripsit ad me ante, et prima sic ut neget se ne Graeca quidem meliora legisse; reliqua ad quendam locum ῥᾳθυμότερα (hoc enim utitur verbo). dic mihi verum: num aut res eum aut χαρακτὴρ non delectat?(Q.fr.2.15.5).

Aristotle attaches particular significance to the homonymy of many central concepts in philosophy and science: that is, to the diversity of ways of being common to a single general concept. His preoccupation with homonymy influences his approach to almost every subject that he considers, and it clearly structures the philosophical methodology that he employs both when criticizing others and when advancing his own positive theories. Where there is homonymy there is multiplicity: Aristotle aims to find the order within this multiplicity, (...) and believes that doing so is crucial to scientific inquiry and philosophical progress.Christopher Shields investigates and evaluates Aristotle's approach to questions about homonymy, characterizing the metaphysical and semantic commitments necessary to establish the homonymy of a given concept. Then, in a series of case-studies, Shields examines in detail some of Aristotle's principal applications of homonymy--to the body, sameness and oneness, life, goodness, and being. Shields's aim is not only to give a fuller understanding of Aristotle's methodology and to illuminate his specific doctrines in a variety of areas, but to show that this methodology remains fruitful today.

Expressives like damn and bastard have, when uttered, an immediate and powerful impact on the context. They are performative, often destructively so. They are revealing of the perspective from which the utterance is made, and they can have a dramatic impact on how current and future utterances are perceived. This, despite the fact that speakers are invariably hard-pressed to articulate what they mean. I develop a general theory of these volatile, indispensable meanings. The theory is built around a class of (...) expressive indices. These determine the expressive setting of the context of interpretation. Expressives morphemes act on that context, actively changing its expressive setting. The theory is multidimensional in the sense that descriptives and expressives are fundamentally different but receive a unified logical treatment. (shrink)

The essays in this volume illuminate a central topic in ethical theory: moral dilemmas. Some contemporary philosophers dispute the traditional view that a true moral dilemma -- a situation in which a person has two irreconcilable moral duties -- cannot exist. This collection provides the historical background to the ongoing debate with selections from Kant, Mill, Bradley, and Ross. The best recent work on the question is represented in essays by Donagan, Foot, Hare, Marcus, Nagel, van Fraassen, Williams, and others.

The norms surrounding pejorative language, such as racial slurs and swear words, are deeply prohibitive. Pejoratives are typically a means for speakers to express their derogatory attitudes. As these attitudes vary along many dimensions and magnitudes, they initially appear to be resistant to a truth-conditional, semantic analysis. The goal of the paper is to clarify the essential linguistic phenomena surrounding pejoratives, survey the logical space of explanatory theories, evaluate each with respect to the phenomena and provide a preliminary assessment of (...) the initial resistance to a truth-conditional analysis.

Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails. I claim that the companions in guilt theorist must understand epistemic reasons as evidential support relations if her argument is to be dialectically effective. I then present a dilemma. Either epistemic reasons are evidential support relations or they are not. If (...) they are not, then the companions in guilt argument fails. If they are, then a reduction of epistemic reasons to evidential support relations becomes available and, consequently, epistemic reasons cease to be a viable ‘companion’ for moral reasons. I recommend this structure of argument over existing strategies within the literature and defend my claims against recent objections from companions in guilt theorists. (shrink)

No existing normative decision theory adequately handles risk. Expected Utility Theory is overly restrictive in prohibiting a range of reasonable preferences. And theories designed to accommodate such preferences (for example, Buchak's (2013) Risk‐Weighted Expected Utility Theory) violate the Betweenness axiom, which requires that you are indifferent to randomizing over two options between which you are already indifferent. Betweenness has been overlooked by philosophers, and we argue that it is a compelling normative constraint. Furthermore, neither Expected nor Risk‐Weighted Expected Utility Theory (...) allow for stakes‐sensitive risk‐attitudes—they require that risk matters in the same way whether you are gambling for loose change or millions of dollars. We provide a novel normative interpretation of Weighted‐Linear Utility Theory that solves all of these problems. (shrink)

Fallacies and Argument Appraisal presents an introduction to the nature, identification, and causes of fallacious reasoning, along with key questions for evaluation. Drawing from the latest work on fallacies as well as some of the standard ideas that have remained relevant since Aristotle, Christopher Tindale investigates central cases of major fallacies in order to understand what has gone wrong and how this has occurred. Dispensing with the approach that simply assigns labels and brief descriptions of fallacies, Tindale provides fuller (...) treatments that recognize the dialectical and rhetorical contexts in which fallacies arise. This volume analyzes major fallacies through accessible, everyday examples. Critical questions are developed for each fallacy to help the student identify them and provide considered evaluations.

Discusses Derrida's writings on Plato, Kant, Hegel, Rousseau, Nietzsche, and Freud.

Christopher Hookway presents a series of studies of themes from the work of the great American philosopher and pragmatist, Charles S. Peirce (1839-1913). These themes center on the question of how we are to investigate the world rationally. Hookway shows how Peirce's ideas about this continue to play an important role in contemporary philosophy.

In Libanius' speechFor the Temples(Or. 30), sometimes regarded as the crowning work of his career, he refers to an unnamed city in which a great pagan temple had recently been destroyed; the date of the speech is disputed, but must be in the 380 s or early 390 s, near the end of the speaker's life. After deploring the actions of a governor appointed by Theodosius, often identified with the praetorian prefect Maternus Cynegius, Libanius continues (30.44–5):Let no-one think that all (...) this is an accusation against you, Your Majesty. For on the frontier with Persia (πρὸς τοῖς ὁρίοις Περσῶν) there lies in ruins a temple which had no equal, as one may hear from all who saw it, so very large was it and so very large the blocks with which it was built, and it occupied as much space as the city itself. Why, amid the terrors of war, to the benefit of the city's inhabitants, those who took the city gained nothing because of their inability to take the temple as well (τοῖς ἑλοῦσι τὴν πόλιν οὐκ ἔχουσι κἀκεῖνον προσεξελεῖν), since the strength of the walls defied every siege-engine. Besides that, one could mount up to the roof and see a very great part of enemy territory, which gives no small advantage in time of war. I have heard some people disputing which of the two sanctuaries was the greater marvel, this one that has gone, or one that one hopes may never suffer in the same way, and contains Sarapis. But this sanctuary, of such a kind and size, not to mention the secret devices of the ceiling and all the sacred statues made of iron that were hidden in darkness, escaping the sun – it has vanished and is destroyed.Jacques Godefroy (Gothofredus), best known for his edition of the Theodosian Code, also produced theeditio princepsof the speechFor the Temples, supplying a Latin translation and extensive notes. He hesitated whether to identify the city in question with Apamea in Syria or with Carrhae, ‘urbs superstitione Gentilicia tum referta’, but opted for a third choice: Edessa, the capital of Osrhoene. In doing so he took for granted that a law of the Theodosian Code (16.10.8), in which the emperors order that a pagan temple in Osrhoene remain open, referred to the same temple; I shall argue below that this is incorrect. Opinion continues to be divided, though with a majority favouring Edessa. But this lay some ten or fifteen miles from the border with Persia, whereas Carrhae was directly on it, and is much more likely than Edessa to have had a temple from which one ‘could observe a vast area of enemy country’. The principal deity of Carrhae (Harran) was Sîn, the Moon God, said by some sources to be male, by others to be female. Describing how Caracalla was assassinated while on a pilgrimage to the god, Cassius Dio says that he had ‘set out from Edessa for Carrhae’, and was murdered on the way: according to Herodian, he was staying in Carrhae when he decided to go in advance of his army ‘and to reach the temple of the Moon, whom the local people greatly revere: the temple is a long way from the city [presumably Carrhae], so as to require a (special) journey’. Another emperor to visit the sanctuary was Julian on his march into Babylonia. Theodoret of Cyrrhus alleges that ‘he entered the sanctuary honoured by the impious’ and cut open a human victim, a woman suspended by the hair, in order to obtain an omen of his future victory.

The literature on the nature of understanding can be divided into two broad camps. Explanationists believe that it is knowledge of explanations that is key to understanding. In contrast, their manipulationist rivals maintain that understanding essentially involves an ability to manipulate certain representations. The aim of this paper is to provide a novel knowledge based account of understanding. More specifically, it proposes an account of maximal understanding of a given phenomenon in terms of fully comprehensive and maximally well-connected knowledge of (...) it and of degrees of understanding in terms of approximations to such knowledge. It is completed by a contextualist semantics for outright attributions of understanding according to which an attribution of understanding is true of one just in case one knows enough about it to perform some contextually determined task. It is argued that this account has an edge over both its explanationist and manipulationist competitors. (shrink)

Plato's Utopia Recast is an illuminating reappraisal of Plato's later works, which reveals radical changes in his ethical and political theory. Christopher Bobonich examines later dialogues, with a special emphasis upon the Laws, and argues that in these late works, Plato both rethinks and revises the basic ethical and poltical positions that he held in his better-known earlier works, such as the Republic. This book will change our understanding of Plato. His controversial moral and political theory, so influential in (...) Western thought, will henceforth be seen in a new light. (shrink)

The paper provides a systematic overview of recent debates in epistemology and philosophy of science on the nature of understanding. We explain why philosophers have turned their attention to understanding and discuss conditions for “explanatory” understanding of why something is the case and for “objectual” understanding of a whole subject matter. The most debated conditions for these types of understanding roughly resemble the three traditional conditions for knowledge: truth, justification and belief. We discuss prominent views about how to construe these (...) conditions for understanding, whether understanding indeed requires conditions of all three types and whether additional conditions are needed.

Schopenhauer's philosophy was formed during the years 1810–18. This chapter looks at the influences that shaped it, principally Kant, but also Plato, and the Upanishads. Schopenhauer aimed at a synthesis of these influences. Although indebted to Kant for the framework of his thought, he developed a conception of metaphysics and a ‘better consciousness’ of objective reality that would be free from the limitations imposed by Kant. Schopenhauer's antagonistic relationship with Fichte, Schelling, and Hegel is also mentioned.
