Background To produce and understand words, humans access the mental lexicon. From a functional perspective, the long-term memory component of the mental lexicon is comprised of three levels: the concept level, the lemma level, and the phonological level. At each level, different kinds of word information are stored. Semantic as well as phonological cues can help to facilitate word access during a naming task, especially when neural dysfunctions are present. The processing corresponding to word access occurs in specific parts of (...) working memory. Neural models for simulating speech processing help to uncover the complex relationships that exist between neural dysfunctions and corresponding behavioral patterns. Methods The Neural Engineering Framework (NEF) and the Semantic Pointer Architecture (SPA) are used to develop a quantitative neural model of the mental lexicon and its access during speech processing. By simulating a picture-naming task (WWT 6-10), the influence of cues is investigated by introducing neural dysfunctions within the neural model at different levels of the mental lexicon. Results First, the neural model is able to simulate the test behavior for normal children that exhibit no lexical dysfunction. Second, the model shows worse results in test performance as larger degrees of dysfunction are introduced. Third, if the severity of dysfunction is not too high, phonological and semantic cues are observed to lead to an increase in the number of correctly named words. Phonological cues are observed to be more effective than semantic cues. Conclusion Our simulation results are in line with human experimental data. Specifically, phonological cues seem not only to activate phonologically similar items within the phonological level. Moreover, phonological cues support higher-level processing during access of the mental lexicon. Thus, the neural model introduced in this paper offers a promising approach to modeling the mental lexicon, and to incorporating the mental lexicon into a complex model of language processing.

A broad sketch for a model of speech production is outlined which describes developmental aspects of its cognitive-linguistic and sensorimotor components. A description of the emergence of phonological knowledge is a central point in our model sketch. It will be shown that the phonological form level emerges during speech acquisition and becomes an important representation at the interface between cognitive-linguistic and sensorimotor processes. Motor planning as well as motor programming are defined as separate processes in our model sketch and it (...) will be shown that both processes revert to the phonological information. Two computational simulation experiments based on quantitative implementations are undertaken to show proof of principle of key ideas of the model sketch: the emergence of phonological information over developmental stages, the adaptation process for generating new motor programs, and the importance of various forms of phonological representation in that process. Based on the ideas developed within our sketch of a production model and its quantitative spell-out within the simulation models, motor planning can be defined here as the process of identifying a succession of executable chunks from a currently activated phoneme sequence and of coding them as raw gesture scores. Motor programming can be defined as the process of building up the complete set of motor commands by specifying all gestures in detail. This full specification of gesture scores is achieved in our model by adapting motor information from phonologically similar syllables or by assembling motor programs from sub-syllabic units.

In Pragmatism’s Evolution, Trevor Pearce demonstrates that the philosophical tradition of pragmatism owes an enormous debt to specific biological debates in the late 1800s, especially those concerning the role of the environment in development and evolution. Many are familiar with John Dewey’s 1909 assertion that evolutionary ideas overturned two thousand years of philosophy—but what exactly happened in the fifty years prior to Dewey’s claim? What form did evolutionary ideas take? When and how were they received by American philosophers? Although (...) the various thinkers associated with pragmatism—from Charles Sanders Peirce to Jane Addams and beyond—were towering figures in American intellectual life, few realize the full extent of their engagement with the life sciences. In his analysis, Pearce focuses on a series of debates in biology from 1860 to 1910—from the instincts of honeybees to the inheritance of acquired characteristics—in which the pragmatists were active participants. If we want to understand the pragmatists and their influence, Pearce argues, we need to understand the relationship between pragmatism and biology. (shrink)

This paper first argues that we can bring out a tension between the following three popular doctrines: (i) the canonical reduction of metaphysical modality to essence, due to Fine, (ii) contingentism, which says that possibly something could have failed to be something, and (iii) the doctrine that metaphysical modality obeys the modal logic S5. After presenting two such arguments (one from the theorems of S4 and another from the theorems of B), I turn to exploring various conclusions we might draw (...) in light of these results, and argue that none comes cost free. In the course of laying out possible responses to my arguments, we'll have a chance to evaluate various doctrines about the interplay between contingency and essence, as well as develop some alternative reductions of metaphysical modality to essence. I don't decisively come down in favor of one response over the others, though I say some things that point towards the conclusion that essence has no role to play in reducing metaphysical modality.

This commentary aims to place Grace de Laguna’s critique of pragmatism in its historical context. It examines her 1904 response to Henry Heath Bawden, her 1909 attack on John Dewey’s immediate empiricism, and her 1910 book Dogmatism and Evolution, focusing on the following question: Why did she describe her approach as an attempt to complete the pragmatists’ Darwinian revolution in logic?

The hole argument purports to show that all spacetime theories of a certain form are indeterministic, including the General Theory of Relativity. The argument has given rise to an industry of searching for a metaphysics of spacetime that delivers the right modal implications to rescue determinism. In this paper, I first argue that certain prominent extant replies to the hole argument—namely, those that appeal to an essentialist doctrine about spacetime—fail to deliver the requisite modal implications. As part of my argument, (...) I show that threats to determinism of the sort brought out by the hole argument are more general than has heretofore been recognized. I then use these results to propose a novel essentialist doctrine about spacetime that successfully rescues determinism, what I call sufficiency metric essentialism. However, I go on to argue that once we realize what an essentialist doctrine about spacetime must look like in order to address the hole argument, we should reject all such doctrines, because they can't fulfill their ambition of improving on standard modal replies to the argument. I close by suggesting some lessons for future work on spacetime and the metaphysics of physics more broadly, and also drawing some general morals for contemporary metaphysics, in particular about (i) whether essence can be used to articulate a precise structuralist doctrine, and (ii) the relationship between essence and modality.

This book considers how language can be appropriately theorized as both a natural and cultural phenomenon. In reaching his conclusion, Pateman draws on a wide range of work in linguistics, philosophy, and social theory, and argues in defense of Chomsky and against Wittgenstein, all within the framework of a realist philosophy of science and contemporary social theory.

In this paper I argue that the “dynamic functionalism” of Dewey’s evolutionary approach to ethics – moral norms emerge to address specific problems but must be constantly readjusted to changing contexts – had its roots in the comparative jurisprudence of Sir Henry Sumner Maine and Oliver Wendell Holmes Jr. First, I will discuss the rise of the comparative sciences in the nineteenth century, part of the backdrop for the work of Maine and various evolutionary anthropologists. Next, I will examine Maine’s (...) Ancient Law (1861), Edward Burnett Tylor’s Primitive Culture (1871), and Holmes’s The Common Law (1881), three related books that set up a dichotomy between existing custom and historical progress. Finally, I will show how this dichotomy was reflected in Dewey’s writing and teaching at the University of Michigan in the early 1890s, including “Anthropology and Law” (1893) and several courses in political philosophy.

The consensus among spacetime substantivalists is to respond to Leibniz's classic shift arguments, and their contemporary incarnation in the form of the hole argument, by pruning the allegedly problematic metaphysical possibilities that generate these arguments. Some substantivalists do so by directly appealing to a modal doctrine akin to anti-haecceitism. Other substantivalists do so by appealing to an underlying hyperintensional doctrine that implies some such modal doctrine. My first aim in this paper is to pose a challenge for all extant forms (...) of this consensus position. My second aim is to show what form substantivalism must take in order to uphold the consensus while addressing this challenge. The result is a novel "plenitudinous" substantivalist view, which predicts that certain modal facts about spacetime are vague or indeterminate. I then argue against this view on independent grounds, concluding that substantivalists should reject the consensus position. The paper also discusses the way forward for substantivalists in light of this conclusion. (shrink)

Formal criteria of theoretical equivalence are mathematical mappings between specific sorts of mathematical objects, notably including those objects used in mathematical physics. Proponents of formal criteria claim that results involving these criteria have implications that extend beyond pure mathematics. For instance, they claim that formal criteria bear on the project of using our best mathematical physics as a guide to what the world is like, and also have deflationary implications for various debates in the metaphysics of physics. In this paper, (...) I investigate whether there is a defensible view according to which formal criteria have significant non-mathematical implications, of these sorts or any other, reaching a chiefly negative verdict. Along the way, I discuss various foundational issues concerning how we use mathematical objects to describe the world when doing physics, and how this practice should inform metaphysics. I diagnose the prominence of formal criteria as stemming from contentious views on these foundational issues, and endeavor to motivate some alternative views in their stead. (shrink)

This article reads Carlyle as a reader of Goethe to recover why he proclaimed Goethe as the `benignant spiritual revolutionist' of modernity and `first of the moderns'. As Goethe's first major English translator, Thomas Carlyle was also arguably the first to grasp the nature and purpose of Goethe's project to interpret modernity as a revolutionary epoch involving changes in consciousness, culture and material development. For Carlyle, Goethe's Faust presents modern consciousness and culture from the side of elegy - as the (...) search by an old man for eternal youth and an infinite world without constraints involving tragic loss. Wilhelm Meisters Lehrjahre, by contrast, presents the same processes from the side of romantic quest, that is, from the perspective of a youth growing into adulthood, as looking into the future with infinite hope. Finally in Wilhelm Meisters Wanderjahre, Carlyle discerns that the radical form of this novel as a discontinuous narrative that embodies movement, change and incompletion enables Goethe to represent the social conditions of moderns as a spiritual challenge and historic achievement. Carlyle's critical perspicacity is evident not least in his choice of Goethe's works to translate as much as his own essays on Goethe's place in modern European letters. In his close reading of Goethe, Carlyle captures the symbolic form of modernity as incorporating three levels of revolutionary transformation of individual consciousness, of culture and of modernity as mythic condition consisting of tragic development, creative destruction and perpetual movement and change. Moderns then are challenged to become authors of their own texts and lives. Carlyle contrasts Goethe's achievement against other primary candidates for the title of modern spiritual revolutionist in ironically Goethean terms: Napoleon (Prometheus), Byron (Faust and Young Werther) and Voltaire (Mephistopheles). Thereafter, the older Carlyle puts aside his critical readings of Goethe to become his own Goethean authority on the modern condition, most notably in his most famous books, Sartor Resartus, The French Revolution, Chartism, On Heroes, and Past and Present. By reading Carlyle as a reader of Goethe we can begin to discern that Carlyle was not only an historian, biographer and political commentator of his own place and times but a critical theorist seeking to interpret the modern epoch, with and beyond Goethe.

Interest in the neural processes underlying decision making has led to a flurry of recent research in the fields of both moral psychology and neuroeconomics. In this paper, we first review some important findings from both disciplines, and then argue that the two fields can mutually benefit each other. A more explicit recognition of the role of values and norms will likely lead to more accurate models of decision making for neuroeconomists, whereas the tasks, insights into neural mechanisms, and mathematical (...) modeling common in neuroeconomic research offer moral psychologists the opportunity to expand their field and move beyond methodological limitations that may have hindered the field’s progress to this point. We conclude by highlighting an exciting group of recent studies that illustrate the potential of research that embraces the integrated moral/neuroeconomic approach that we suggest here. (shrink)

Significant challenges arise for clinical care teams when a patient or surrogate decision-maker hopes a miracle will occur. This article answers the question, “How should clinical bioethicists respond when a medical decision-maker uses the hope for a miracle to orient her medical decisions?” We argue the ethicist must first understand the complexity of the miracle-invocation. To this end, we provide a taxonomy of miracle-invocations that assist the ethicist in analyzing the invocator's conceptions of God, community, and self. After the ethicist (...) appreciates how these concepts influence the invocator's worldview, she can begin responding to this hope with specific practices. We discuss these practices in detail and offer concrete recommendations for a justified response to the hope for a miracle. (shrink)

The word ‘environment’ has a history. Before the mid-nineteenth century, the idea of a singular, abstract entity—the organism—interacting with another singular, abstract entity—the environment—was virtually unknown. In this paper I trace how the idea of a plurality of external conditions or circumstances was replaced by the idea of a singular environment. The central figure behind this shift, at least in Anglo-American intellectual life, was the philosopher Herbert Spencer. I examine Spencer’s work from 1840 to 1855, demonstrating that he was exposed (...) to a variety of discussions of the ‘force of circumstances’ in this period, and was decisively influenced by the ideas of Auguste Comte in the years preceding the publication of Principles of psychology (1855). It is this latter work that popularized the word ‘environment’ and the corresponding idea of organism–environment interaction—an idea with important metaphysical and methodological implications. Spencer introduced into the English-speaking world one of our most enduring dichotomies: organism and environment. (shrink)

A number of studies have investigated and found a significant relationship among economic wealth, Hofstede’s national culture dimensions, and software piracy rates (SPR). No study, however, has examined the relationship between economic wealth, culture, and the fact that national SPRs have been declining steadily since 1994. Using a larger sample than has previously been available (57 countries), we confirm the expected negative relationship between economic wealth, culture (individualism and masculinity) and levels of software piracy. The rate of decline in software (...) piracy, however, is found to be a cultural phenomenon, with two factors (power distance (PDI) and uncertainty avoidance (UAI)) working in opposition. Similar results are found for a subset of 37 relatively poor countries. This suggests that, while the rise in economic wealth seen for most countries should lead to a reduction in software piracy, the rate of decline is determined by cultural factors. Global strategies for dealing with software piracy are discussed. (shrink)

A large body of research has examined the relationship between moral intensity (MI) and the four‐component model of morality, typically, by separating MI into its constituent dimensions and regressing them individually against the four‐component model. This approach, however, violates the definition of MI as a single construct. To correct this problem, we develop and test a model of the impact of MI as a single, 6‐item formative construct. We find that when MI is taken into account, moral recognition is not (...) significant. MI does, however, serve as a strong trigger for judgment. We also determine that splitting MI into multiple factors does not significantly affect the results, confirming the assertion that MI is a single, coherent construct. (shrink)

In Metaphor and Film, Trevor Whittock demonstrates that feature films are permeated by metaphors that were consciously introduced by directors. An examination of cinematic metaphor forces us to reconsider the nature of metaphor itself, and the ways by which such visual imagery can be recognised and understood, as well as interpreted. Metaphor and Film identifies the principal forms of cinematic metaphor, and also provides an analysis of the mental operations that one must bring to it. Recent developments in cognitive (...) psychology, especially those relating to the nature and formation of categories, are called upon to explain these processes. Metaphor and Film ranges widely over film theory as it does over philosophical, literary, linguistic, and psychological accounts of metaphor. Particularly useful to those studying film, literature, and aesthetics, this study is also a provocative contribution to an important debate in which film theorists and philosophers are currently engaged.

Trevor Pearce examines Mead’s early intellectual development and shows in detail how difficult it was for a young Christian at the time to integrate Darwin into his worldview. Pearce explores the deep existential crisis that resulted from these difficulties. Based on new and newly reevaluated biographical material, Pearce traces the development of Mead’s views through his years in college, in a longer phase of existential reorientation, and as a student of philosophy and psychology. Pearce also shows how Mead’s education (...) with Josiah Royce at Harvard and Wilhelm Dilthey in Berlin—both authors who saw the doctrine of evolution as a means to come to a better understanding of the human being’s “spiritual” nature—was key to resolving his early intellectual and personal problems and continued to form the center of his later work.

Background independence begins life as an informal property that a physical theory might have, often glossed as 'doesn't posit a fixed spacetime background'. Interest in trying to offer a precise account of background independence has been sparked by the pronouncements of several theorists working on quantum gravity that background independence embodies in some sense an essential discovery of the General Theory of Relativity, and a feature we should strive to carry forward to future physical theories. This paper has two goals. (...) The first is to investigate what a world must be like in order to be truly described by a background independent theory given extant accounts of background independence. The second is to argue that there are no non-empirical reasons to be more confident in theories that satisfy extant accounts of background independence than in theories that don't. The paper concludes by drawing a general moral about a way in which focussing primarily on mathematical formulations of our physical theories can adversely affect debates in the metaphysics of physics.

Lei, a twenty‐seven‐year‐old Mandarin speaker, visits the United States seeking curative treatments for his acute myeloid leukemia. His mother, Hua, has traveled with him. Neither she nor Lei speak English, and the hospital does not have an onsite professional Mandarin‐speaking interpreter. Using a professional interpreter over the phone, Lei's oncologist, Dr. Branson, attempts to initiate a face‐to‐face goals‐of‐care conversation with Hua as the surrogate decision‐maker. Dr. Branson explains that Lei has “only weeks to months to live” and recommends initiating comfort‐care‐only (...) measures, but Hua says that she wants (and that Lei would want) continued aggressive measures. Hua says that her son might be a candidate for a phase I trial. Eventually, Dr. Branson brings in Dr. Chou, a Mandarin‐speaking resident to provide face‐to‐face interpretation. Hua insists that “there must be more standard therapies available” and says that she will wait until the trial begins. She begins crying, and the meeting disintegrates. Following this, Dr. Branson calls for an ethics consultation for “help in end‐of‐life communicating and reconciling discordance about prognostic information.”How should the ethicist use the institution's interpreter services?

John Nolt’s “Hope, Self-Transcendence, and Environmental Ethics” is a unique attempt to defend a partial biocentrism – the view that we should regard a significant portion of non-sentient life (as well as sentient life) as having direct moral standing. After defending a general duty to optimize human hope, Nolt argues that this duty requires us to become self-transcendent toward living things in nature. Self-transcendence refers to an intentional state of valuing the good of some object other than yourself as an (...) end. Thus, though Nolt begins from an anthropocentric starting point, his argument reaches a conclusion that biocentrists should find palatable (though some may feel it does not go far enough, since it does not grant direct moral standing to all life). Although Nolt’s argument is novel and thought-provoking, I contend that it is nevertheless unsuccessful because it cannot overcome three significant difficulties. First, it is not clear that self-transcendence toward living things in nature would actually optimize hope. Second, the general duty to optimize hope does not entail an individual duty to seek self-transcendence toward living things in nature. Third, the value of the hope attained by achieving self-transcendence toward non-sentient life seems astronomically minute compared to the hope attained by achieving self-transcendence toward sentient life and especially toward human life. In light of these difficulties, I conclude the essay by arguing that self-transcendence is best directed only toward sentient living things. (shrink)

In this lively series of conversations with writer Michel Treguer, René Girard revisits the major concepts of mimetic theory and explores science, democracy, and the nature of God and freedom. Girard affirms that “our unprecedented present is incomprehensible without Christianity.” Globalization has unified the world, yet civil war and terrorism persist despite free trade and economic growth. Because of mimetic desire and the rivalry it generates, asserts Girard, “whether we’re talking about marriage, friendship, professional relationships, issues with neighbors or matters (...) of national unity, human relations are always under threat.” Literary masters including Marivaux, Dostoevsky, and Joyce understood this, as did archaic religion, which warded off violence with blood sacrifice. Christianity brought a new understanding of sacrifice, giving rise not only to modern rationality and science but also to a fragile system that is, in Girard’s words, “always teetering between a new golden age and a destructive apocalypse.” Treguer, a skeptic of mimetic theory, wonders: “Is what he’s telling me true...or is it just a nice story, a way of looking at things?” In response, Girard makes a compelling case for his theory.

In this paper I argue that the technologizing of most things in our daily lives, from work and education to finance and leisure, can be seen to promote a loss of the tangible and a rootlessness for human societies, causing a disorientation in the knowledge and beliefs acquired over millennia. Arendt’s proposal that ‘the earth is the very quintessence of the human condition’ (1958, p. 2) appears to be challenged as digital interactions create new spaces that coax humans away from (...) a focus on their physical world. Instantaneity and simultaneity avoid the historic conditions of humanity in relation to time and place, while the hyperreal images and simulations of the virtual either distort reality or do not depict anything with a real existence. Stiegler goes so far as to suggest that human knowledge and memory is being confiscated by technology. The acceleration of reality, as a condition of the instant, erases the beginning as much as the end, and past, present and future are diminished as contemporary becomes simply temporary. My position, while not utopian, does not seek to be irrationally dystopian and accepts that there is much in technology that advances human physical well-being and thought. It is, however, cautionary in its concern that private technology corporations, having seconded science, actively seek to increase their market and control over hyperconnectivity, thinking, knowledge and the human condition. I draw on the writings of Stiegler and Virilio in particular, both of whom acknowledge a debt to Heidegger. (shrink)

We challenge the standard interpretation of pain asymbolia (PA), a neuropsychiatric condition that causes unusual reactions to pain stimuli. The standard interpretation asserts that PA subjects experience pain but lack important features of the experience. However, we argue that the clinical evidence for PA does not support this interpretation and that the arguments put forward by the defenders of the standard interpretation end up making self-contradicting claims. Finally, we suggest that the best interpretation of the available evidence is to take (...) a deflationist stance toward PA, at least until further evidence becomes available. (shrink)

f gravity is examined in the context of a five-dimensional Kaluza-Klein theory with degenerate metric. In this theory electromagnetism is described by two vector fields, and there is a reflection symmetry between them which unifies them with gravitation. For matter, it is shown how the Lagrangian may be any function and still generate the same equations of motion, provided that some simple conditions are satisfied. The field equations are derived, and it is found that f gravity is not consistent with (...) the reflection symmetry. (shrink)
