We welcome the proposal to use forward models to understand predictive processes in language processing. However, Pickering & Garrod (P&G) miss the opportunity to provide a strong framework for future work. Forward models need to be pursued in the context of learning. This naturally leads to questions about what prediction error these models aim to minimize.

Unification grammars are known to be Turing-equivalent; given a grammar G and a word w, it is undecidable whether w L(G). In order to ensure decidability, several constraints on grammars, commonly known as off-line parsability (OLP), were suggested, such that the recognition problem is decidable for grammars which satisfy OLP. An open question is whether it is decidable if a given grammar satisfies OLP. In this paper we investigate various definitions of OLP and discuss their interrelations, proving that some of (...) the OLP variants are indeed undecidable. We then present a novel, decidable OLP constraint which is more liberal than the existing decidable ones. (shrink)

People's treatment of others (humans, nonhuman animals, or other entities) often depends on whether they think the entity is worthy of moral concern. Recent work has begun to investigate which entities are included in a person's moral circle, examining how certain target characteristics (e.g., species category, perceived intelligence) and judge characteristics (e.g., empathy, political orientation) shape moral inclusion. However, the relative importance of target and judge characteristics in predicting moral inclusion remains unclear. When predicting whether a person will deem an (...) entity worthy of moral consideration, how important is it to know who is making the judgment (i.e., characteristics of the judge), who is being judged (i.e., characteristics of the target), and potential interactions between the two factors? Here, we address this foundational question by conducting a variance component analysis of the moral circle. In two studies with participants from the Netherlands, the United States, the United Kingdom, and Australia (N = 836), we test how much variance in judgments of moral concern is explained by between‐target differences, between‐judge differences, and by the interaction between the two factors. We consistently find that all three components explain substantial amounts of variance in judgments of moral concern. Our findings provide two important insights. First, an increased focus on interactions between target and judge characteristics is needed, as these interactions explain as much variance as target and judge characteristics separately. Second, any theoretical account that aims to provide an accurate description of moral inclusion needs to consider target characteristics, judge characteristics, and their interaction. (shrink)

The first classification of general types of transition between phases of matter, introduced by Paul Ehrenfest in 1933, lies at a crossroads in the thermodynamical study of critical phenomena. It arose following the discovery in 1932 of a suprising new phase transition in liquid helium, the “lambda transition,” when W. H. Keesom and coworkers in Leiden, Holland observed a λhaped “jump” discontinuity in the curve giving the temperature dependence of the specific heat of helium at a critical value. This apparent (...) jump led Ehrenfest to introduce a classification of phase transitions on the basis of jumps in derivatives of the free energy function. This classification was immediately applied by A.J. Rutgers to the study of the transition from the normal to superconducting state in metals. Eduard Justi and Max von Laue soon questioned the possibility of its class of “second-order phase transitions” -- of which the “lambda transition was believed to be the arche type -- but C.J. Gorter and H.B.G. Casimir used an “order parameter to demonstrate their existence in superconductors. As a crossroads of study, the Ehrenfest classification was forced to undergo a slow, adaptive evolution during subsequent decades. During the 1940s the classification was increasingly used in discussions of liquid-gas, order-disorder, paramagnetic-ferromagnetic and normal-super-conducting phase transitions. Already in 1944 however, Lars Onsagers solution of the Ising model for two-dimensional magnets was seen to possess a derivative with a logarithmic divergence rather than a jump as the critical point was approached. In the 1950s, experiments further revealed the lambda transition in helium to exhibit similar behavior. Rather than being a prime example of an Ehrenfest phase transition, the lambda transition was seen to lie outside the Ehrenfest classification. The Ehrenfest scheme was then extended to include such singularities, most notably by A. Brain Pippard in 1957, with widespread acceptance. During the 1960s these logarithmic infinities were the focus of the investigation of “scaling” by Leo Kadanoff, B. Widom and others. By the 1970s, a radically simplified binary classification of phase transitions into “first-order” and “continuous” transitions was increasingly adopted. (shrink)

Like every major new technology, genetic engineering is affecting the hopes and fears of many people. The risks involved are perceived differently by different groups. One group regards genetic engineering as a simple extension of older techniques with no special risks, e.g. traditional breeding. This conservative denial of special risks is confronted with a different kind of conservatism from a group which, in the name of the preservation of nature, opposes any kind of genetic engineering. A third group, rooted in (...) the liberal tradition, is prepared to accept the risks of genetic engineering as long as they are outweighed by prospective benefits. The liberal as well as the two conservative approaches, however, face serious difficulties in trying to develop a sound ethical argument concerning genetic engineering. In order to avoid these difficulties, an ethical approach focused on paradigmatic examples of good and evil is proposed. Such examples constitute rules of moral description, much as standards of measurement constitute rules of physical description. These rules are elaborated and interpreted in processes of social learning. In the present state of development of genetic engineering, such social learning requires appropriate institutional procedures. (shrink)

L'interrogation sur le rôle que jouent aujourd'hui les convictions religieuses en philosophie des sciences peut paraître une démarche surprenante, car trop souvent la religion est rejetée hors du champ de l'enquête philosophique. Cet ouvrage ose au contraire demander dans quelle mesure les options religieuses d'un penseur influencent sa conception de l'ordre cosmique. L'examen du concept de loi de la nature s'inscrit dans une quête plus large : il permet de tester la façon dont les choix épistémologiques d'un individu dépendent de (...) sa vision du monde et ainsi de porter une attention particulière aux interactions entre science, épistémologie et religion. L'étude porte sur quatre figures des plus marquantes du débat contemporain sur les lois de la nature : David Armstrong, Nancy Cartwright, David Lewis et Bas van Fraassen. L'analyse de leurs écrits, approfondie d'entretiens personnels, fait ressortir pour chacun les liens qui existent entre sa posture religieuse et son compte rendu de la légalité naturelle. (shrink)

This book offers an introduction to the Sophists of fifth-century Athens and a new overall interpretation of their thought. Since Plato first animadverted on their activities, the Sophists have commonly been presented as little better than intellectual mountebanks - a picture which Professor Kerferd forcefully challenges here. Interpreting the evidence with care, he shows them to have been part of an exciting and historically crucial intellectual movement. At the centre of their teaching was a form of relativism, most famously expressed (...) by Protagoras as 'Man is the measure of all things', and which they developed in a wide range of views - on knowledge and argument, virtue, government, society, and the gods. On all these subjects the Sophists did far more than simply provoke Plato to thought. Their contributions were substantial and serious; they inaugurated the debate on many central philosophical questions and decisively shifted the focus of philosophical attention from the cosmos to man.

La figure de l’entrepreneur est aujourd’hui utilisée dans une grande variété de discours publics. Ce travail cherche à remonter à l’une des sources théoriques de la constitution de cette figure : la théorie de l’entrepreneur de Schumpeter (1911a et 1911b). Ce retour montre que Schumpeter, dans son contexte intellectuel et théorique, est amené à importer une anthropologie philosophique en économie, celle de Nietzsche, auteur largement lu dans l’Autriche du début du xxe siècle. En transposant, à l’intérieur de sa théorie économique, (...) certaines caractéristiques majeures du grand homme créatif nietzschéen dans la figure de l’entrepreneur, Schumpeter développe une explication originale de la nature dynamique du marché et de l’évolution économique. Néanmoins il importe aussi de Nietzsche une série d’ambiguïtés, notamment en ce qui concerne l’origine de l’exceptionnalité individuelle de l’entrepreneur, et plus particulièrement de sa puissance créatrice. Une seconde ambiguïté est très largement héritée, qui concerne l’extension du modèle de l’individu entrepreneur : constitue-t-il une théorie de l’action valable pour tous les individus ou uniquement pour un type d’individus particuliers? Comment concilier exceptionnalité de l’entrepreneur et norme d’un entreprenariat pour tous? La dernière partie de ce travail s’attache ainsi à explorer ces ambiguïtés, qui apparaissent chez Schumpeter et ses successeurs, notamment Israël Kirzner.Codes JEL : B13, B25, B31, B40. (shrink)

Recent work in quantum information science has produced a revolution in our understanding of quantum entanglement. Scientists now view entanglement as a physical resource with many important applications. These range from quantum computers, which would be able to compute exponentially faster than classical computers, to quantum cryptographic techniques, which could provide unbreakable codes for the transfer of secret information over public channels. These important advances in the study of quantum entanglement and information touch on deep foundational issues in both physics (...) and philosophy. This interdisciplinary volume brings together fourteen of the world's leading physicists and philosophers of physics to address the most important developments and debates in this exciting area of research. It offers a broad spectrum of approaches to resolving deep foundational challenges - philosophical, mathematical, and physical - raised by quantum information, quantum processing, and entanglement. This book is ideal for historians, philosophers of science and physicists"--Provided by publisher. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.3 (2003) 227-231 [Access article in PDF] World Traveling as a Clinical Methodology for Psychiatric Care Suzanne M. Jaeger Keywords embodiment, dialogical consciousness, interpersonal communication, epistemic responsibility, self-knowledge, understanding IN HER ARTICLE "Moral Tourists and World Travelers," Nancy Potter suggests a way in which psychiatrists and psychologists could gain a better understanding of their mentally ill patients' experiences. Rather than assuming that hallucinations and (...) incoherent speech and behavior are merely senseless disconnections from reality, Potter argues that mental health care clinicians ought to spend time engaging patients on their own terms. Even when mental illness is a result of brain disease, much can be learned about the patient's experiences of their disease by temporarily setting aside the scientific frameworks of diagnosis and medical treatment. Potter uses Maria Lugones' concept of world traveling and recommends playfully accepting, and even entering into the patient's world (Lugones 1990). She calls world traveling a methodology and explains it in some detail. Moreover, at the close of her essay, Potter suggests that clinicians have a moral obligation to understand the mentally ill patient's world from the patient's perspective. This obligation is based on an appeal to our sense of what it is to be a responsible knower who attends to issues of trust and truth. Relying on arguments made by Lorraine Code (1987), Potter asserts that to try to understand the other's perspective is the responsible thing to do.My discussion focuses on the notion of play to which Potter appeals, as well as on what she sees as the moral obligation of clinicians to communicate with their mentally ill patients in extra-professional ways. This moral obligation arises because (a) the theoretical and professional frameworks of medical science are seen as inadequate, and (b) playfulness opens up mutually respectful, authentic interaction between persons. I generally agree with Potter's claims, and I want to situate them in the wider framework of an epistemological debate about the status of our knowledge of others. A broader context will help to elucidate the strengths of Potter's analysis as well as some points for critical discussion. I begin with the relationship of trust between clinicians and patients.Few people would disagree with the claim that patients need to be able to trust that their physicians are not harming them, but helping them to get better. If patients feel misunderstood, they will not trust their caretakers. This is probably even truer for psychiatric patients, whose conditions and loss of autonomy make establishing trust even more challenging. Psychiatric patients [End Page 227] often have their own ways of compensating for the symptoms of their mental illness. If either their will to survive or their compensatory strategies go unrecognized or misinterpreted, patients may respond by rejecting the well-intentioned efforts of caretakers to restore them to a degree of ease, measured as it must be by the standards of the professionals under whose care the patient remains. 1 Despite the fact that these standards are established through scientific testing procedures for the treatment of diseases, they may be experienced by patients as indifferent to the particular and unique features of their condition. Nestled within the issue of trust is thus a question of truth.Although current scientific knowledge of the human brain, and of human behavior, has made available a range of sophisticated therapies and psychotropic drugs, there are still many mental illnesses that leave families and clinicians wondering whether the treatment plans are providing any help. Alzheimer's disease and schizophrenia are two examples. There is a difference between, on the one hand, containing the patient's behavior by admitting the patient to a psychiatric ward and managing symptoms with psychotropic medications, and, on the other hand, understanding what is happening for the patient, from his or her perspective. Although psychiatric patients may not have a realistic sense of either their abilities or the extent and nature of their disease, there may be much about their experiences that ought to be known and understood by the professionals caring for them...

Evolutionary systems biology (ESB) aims to integrate methods from systems biology and evolutionary biology to go beyond the current limitations in both fields. This article clarifies some conceptual difficulties of this integration project, and shows how they can be overcome. The main challenge we consider involves the integration of evolutionary biology with developmental dynamics, illustrated with two examples. First, we examine historical tensions between efforts to define general evolutionary principles and articulation of detailed mechanistic explanations of specific traits. Next, these (...) tensions are further clarified by considering a recent case from another field focused on developmental dynamics: stem cell biology. In the stem cell case, incompatible explanatory aims block integration. Experimental approaches aim at mechanistic explanation while dynamical system models offer explanation in terms of general principles. We then discuss an ESB case in which integration succeeds: search for general attractors using a dynamical systems framework synergizes with the experimental search for detailed mechanisms. Contrasts between the positive and negative cases suggest general lessons for achieving an integrated understanding of developmental and evolutionary dynamics. The key integrative move is to acknowledge two complementary aims, both relevant to explanation: identifying the space of possible dynamic states and trajectories, and mechanistic understanding of causal interactions underlying a specific phenomenon of interest. These two aims can support one another in a joint project characterizing dynamic aspects of evolving lineages. This more inclusive project can lead to insights that cannot be reached by either approach in isolation. (shrink)

The positive operator (valued) measures (POMs) allow one to generalize the notion of observable beyond the traditional one based on projection valued measures (PVMs). Here, we argue that this generalized conception of observable enables a consistent notion of unsharp reality and with it an adequate concept of joint properties. A sharp or unsharp property manifests itself as an element of sharp or unsharp reality by its tendency to become actual or to actualize a specific measurement outcome. This actualization tendency—or potentiality—of (...) a property is quantified by the associated quantum probability. The resulting single-case interpretation of probability as a degree of reality will be explained in detail and its role in addressing the tensions between quantum and classical accounts of the physical world will be elucidated. It will be shown that potentiality can be viewed as a causal agency that evolves in a well-defined way. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units (...) affect speakers’ preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.

This book traces the intellectual revolution initiated by Thales in the sixth century BC to its culmination in the metaphysics of Parmenides.

There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self-paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting (...) the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times. We additionally replicated previously observed effects of expectation violation, orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension. (shrink)
