The Turing Test (TT), as originally specified, centres on theability to perform a social role. The TT can be seen as a test of anability to enter into normal human social dynamics. In this light itseems unlikely that such an entity can be wholly designed in an off-line mode; rather a considerable period of training insitu would be required. The argument that since we can pass the TT,and our cognitive processes might be implemented as a Turing Machine(TM), that consequently a (...) TM that could pass the TT could be built, isattacked on the grounds that not all TMs are constructible in a plannedway. This observation points towards the importance of developmentalprocesses that use random elements (e.g., evolution), but in these casesit becomes problematic to call the result artificial. This hasimplications for the means by which intelligent agents could bedeveloped. (shrink)

I examine one of the conceptual cornerstones of the field known as computational neuroscience, especially as articulated in Churchland et al. (1990), an article that is arguably the locus classicus of this term and its meaning. The authors of that article try, but I claim ultimately fail, to mark off the enterprise of computational neuroscience as an interdisciplinary approach to understanding the cognitive, information-processing functions of the brain. The failure is a result of the fact that the authors provide no (...) principled means to distinguish the study of neural systems as genuinely computational/information-processing from the study of any complex causal process. I then argue for two things. First, that in order to appropriately mark off computational neuroscience, one must be able to assign a semantics to the states over which an attempt to provide a computational explanation is made. Second, I show that neither of the two most popular ways of trying to effect such content assignation -- informational semantics and 'biosemantics' -- can make the required distinction, at least not in a way that a computational neuroscientist should be happy about. The moral of the story as I take it is not a negative one to the effect that computational neuroscience is in principle incapable of doing what it wants to do. Rather, it is to point out some work that remains to be done. (shrink)

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...) parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language. Key Words: efference copies; emulation theory of representation; forward models; Kalman filters; motor control; motor imagery; perception; visual imagery. (shrink)

When first published twenty years ago, The Logic of Medicine presented a new way of thinking about clinical medicine as a scholarly discipline as well as a profession. Since then, advances in research and technology have revolutionized both the practice and theory of medicine. In this new, extensively rewritten edition, Dr. Murphy includes changes to show how these different areas of scholarship may affect details of "the logic of medicine" without compromising its fundamental coherence. New to this edition are discussions (...) of the challenge of the flood of new empirical data, new ideas in genetics, molecular biology, homeostasis, pathogenesis, cancer, aging, and Alzheimer's disease. Murphy also comments on such new theoretical topics as dynamic systems, chaos, and fractals and their impact on the burgeoning fields of philosophy and practice of medicine. Written with medical students in mind, the book includes a glossary, many new examples, and problems for solutions with comments on each. An entirely new chapter deals with modeling. Clinicians and researchers will also find the principles thought-provoking and illuminating. (shrink)

Using the Godel incompleteness result for leverage, Roger Penrose has argued that the mechanism for consciousness involves quantum gravitational phenomena, acting through microtubules in neurons. We show that this hypothesis is implausible. First the Godel result does not imply that human thought is in fact non-algorithmic. Second, whether or not non-algorithmic quantum gravitational phenomena actually exist, and if they did how that could conceivably implicate microtubules, and if microtubules were involved, how that could conceivably implicate consciousness, is entirely speculative. Third, (...) cytoplasmic ions such as calcium and sodium are almost certainly present in the microtubule pore, barring the quantum-mechanical effects Penrose envisages. Finally, physiological evidence indicates that consciousness does not directly depend on microtubule properties in any case, rendering doubtful any theory according to which consciousness is generated in the microtubules.

This brief commentary has three goals. The first is to argue that ‘‘framework debate’’ in cognitive science is unresolvable. The idea that one theory or framework can singly account for the vast complexity and variety of cognitive processes seems unlikely if not impossible. The second goal is a consequence of this: We should consider how the various theories on offer work together in diverse contexts of investigation. A final goal is to supply a brief review for readers who are compelled (...) by these points to explore existing literature on the topic. Despite this literature, pluralism has garnered very little attention from broader cognitive science. We end by briefly considering what it might mean for theoretical cognitive science. (shrink)

The Philosophy of Matter is a journey in thinking through the material fate of the earth itself; its surfaces and undercurrrents, ecologies, environments and irreparable cracks. With figures such as Spinoza, Gilles Deleuze and Michel Serres as philosophical guides and writings on New Materialism, Posthumanism and Affect Theory as intellectual context, Rick Dolphijn proposes a radical rethinking of some of the basic themes of philosophy: subjectivity, materiality, body (both human and otherwise) and the act of living. This rethink is (...) a work of imagination and meditation in order to conceive of "another earth for another people". It is a homage to courageous thinking that dares to question the religious, capitalist and humanist realities of the day. A poetic philosophy of how to live in troubling times when even the earth beneath us feels unstable, Dolphijn offers a way to think about the world with depth, honesty and glimpses of hope. (shrink)

Dans un passage de Physique iii (7, 207b15-21), Aristote s’exprime d’une manière qui suppose valide l’implication suivante : « Si une grandeur peut être infinie en puissance, une telle grandeur peut aussi être infinie en acte ». Cette implication a intrigué les commentateurs tant anciens et médiévaux que modernes. Ces derniers se sont en général bornés à constater que l’implication n’est pas logiquement valide, sans expliquer comment et en quel sens Aristote avait pu la tenir pour telle. En rapprochant le (...) passage précité d’un autre passage de Physique iii (6, 206b16-27), le présent article en propose une interprétation qui semble lever toutes les difficultés. Au Moyen Age, le sens de l’implication a été très discuté, et l’interprétation proposée ici a été vue et soutenue par plusieurs commentateurs : on l’étudie chez quelques-uns de ceux-ci en situant leur position dans le cadre du débat médiéval sur la question, notamment en référence aux deux interprétations alors fameuses proposées par Averroès.

Michel Serres captures the urgencies of our time; from the digital revolution to the ecological crisis to the future of the university, the crises that code the world today are addressed in an accessible, affirmative and remarkably original analysis in his thought. This volume is the first to engage with the philosophy of Michel Serres, not by writing 'about' it, but by writing 'with' it. This is done by expanding upon the urgent themes that Serres works on; by furthering his (...) materialism, his emphasis on communication and information, his focus on the senses, and the role of mathematics in thought. His famous concepts, such as the parasite, 'amis de viellesse', and the algorithm are applied in 21st century situations. With contributions from an international and interdisciplinary team of authors, these writings tackle the crises of today and affirm the contemporary relevance of Serres' philosophy. (shrink)

In Knowing Emotions, Furtak argues that it is only through the emotions that we can perceive meaning in life, and only by feeling emotions that we are able to recognize the value or significance of anything whatsoever. Our affective responses and dispositions therefore play a critical role in human existence, and their felt quality is intimately related to the awareness they provide.

Groundhog Day (Harold Ramis, 1993) and Only Lovers Left Alive (Jim Jarmusch, 2013) are fantasy films that use the device of practical immortality in order to raise important philosophical questions about what constitutes a good life and to explore the nature of romantic love. Groundhog Day provides fairly conventional answers about how to live a good life by focusing on issues of spiritual redemption, selflessness, and developing one’s human potential. In contrast, Lovers provides a dark portrayal of a civilization on (...) the brink of extinction but offers a glimmer of hope for the future. The lifestyle and values of married vampires Adam and Eve represent an alternative vision of the core values needed to sustain a better world: greater reliance on human imagination, maintaining a sense of wonder and curiosity about the world, creating and appreciating works of art and living in harmony with the natural world. Both films also offer a perspective on the importance of romantic love in living a good life. Although these perspectives often diverge from one another, they do overlap in some interesting ways. The style of film criticism used in this paper is inspired by the film philosophy of Stanley Cavell. (shrink)

Globally, chronic disease and conditions such as diabetes, cardiovascular disease, depression and cancer are the leading causes of morbidity and mortality. Why, then, are public health efforts and programs aimed at preventing chronic disease so difficult to implement and maintain? Also, why is primary care—the key medical specialty for helping persons with chronic disease manage their illnesses—in decline? Public health suffers from its often being socially controversial, personally intrusive, irritating to many powerful corporate interests, and structurally designed to be largely (...) invisible and, as a result, taken for granted. Primary care struggles from low reimbursements, relative to specialists, excessive paperwork and time demands that are unattractive to medical students. Our paper concludes with a discussion of why the need for more aggressive public health and redesigned primary care is great, will grow substantially in the near future, and yet will continue to struggle with funding and public popularity.

I argue against a growing radical trend in current theoretical cognitive science that moves from the premises of embedded cognition, embodied cognition, dynamical systems theory and/or situated robotics to conclusions either to the effect that the mind is not in the brain or that cognition does not require representation, or both. I unearth the considerations at the foundation of this view: Haugeland's bandwidth-component argument to the effect that the brain is not a component in cognitive activity, and arguments inspired by (...) dynamical systems theory and situated robotics to the effect that cognitive activity does not involve representations. Both of these strands depend not only on a shift of emphasis from higher cognitive functions to things like sensorimotor processes, but also depend on a certain understanding of how sensorimotor processes are implemented - as closed-loop control systems. I describe a much more sophisticated model of sensorimotor processing that is not only more powerful and robust than simple closed-loop control, but for which there is great evidence that it is implemented in the nervous system. The is the emulation theory of representation, according to which the brain constructs inner dynamical models, or emulators, of the body and environment which are used in parallel with the body and environment to enhance motor control and perception and to provide faster feedback during motor processes, and can be run off-line to produce imagery and evaluate sensorimotor counterfactuals. I then show that the emulation framework is immune to the radical arguments, and makes apparent why the brain is a component in the cognitive activity, and exactly what the representations are in sensorimotor control.

b>: In this article I outline, apply, and defend a theory of natural representation. The main consequences of this theory are: i) representational status is a matter of how physical entities are used, and specifically is not a matter of causation, nomic relations with the intentional object, or information; ii) there are genuine (brain-)internal representations; iii) such representations are really representations, and not just farcical pseudo-representations, such as attractors, principal components, state-space partitions, or what-have-you;and iv) the theory allows us to (...) sharply distinguish those complex behaviors which are genuinely cognitive from those which are merely complex and adaptive.

Work injury compensation and pensions are often determined according to medical disability rating scales attributing a percentage to each impaired body part or function. Incorporated into central medical–administrative networks of committees and examinations, these produce disability as a calculable space. This article examines the specific case of the Israeli National Insurance regulations regarding work injuries of 1956 and analyzes the shifted order they set. Looking at this system in the specific historical context of transition from the British Mandate workmen’s compensation (...) system to the “disability percentages” system, provides insight into the process of structuring and stabilizing durable numerical forms and the production of centralized government. Drawing on conceptualizations regarding the sociotechnical role of classification systems, I contend that through encoding and calculating classifications of disability, heterogeneity is eliminated and an ordering based on physiology is “black boxed,” illustrating the importance of technoscientific formations in structuring the “medical model of disability.”.

There is a large literature on technology adoption and environmental management in agriculture. Included in this literature are debates about the role world view or attitudinal variables play in adoption decisions, and whether smaller farms or larger farms exhibit superior environmental performance or differ in commitment to environmental values. In this paper we attempt to extend the literature in this area by proposing and measuring discrete environmental management approaches among sixty-six farmers in Northern New York. Using key informants interviews, purposeful (...) sampling of farmers and a mail survey we find two environmental management types: (1) the larger-scale conservation farmer; and (2) the alternative/ecological farmer.

A community's abilities to promote health and maximize its response to public health threats require fulfillment of one of the four elements of public health legal preparedness, the capacity to effectively coordinate law-based efforts across different governmental jurisdictions, as well as across multiple sectors and disciplines. Government jurisdictions can be viewed “vertically” in that response efforts may entail coordination in the application of laws across multiple levels, including local, state, tribal, and federal governments, and even with international organizations. Coordination of (...) legal responses to public health emergencies also may involve a horizontal dimension comprising numerous and diverse sectors, such as public health, public and private health care, emergency management, education, law enforcement, the judiciary, and the military.Although responses to many acute health threats can implicate multiple jurisdictions and sectors, the jurisdictional and sectoral dimensions of legal preparedness are complex and may vary substantially by the nature of a threat, its geographic and geopolitical extent, and the operational response demanded.

This study investigates the relations between narrative experiences and film enjoyment, and explores the possibility that transportability and perceived realism facilitate narrative experience and indirectly influence enjoyment. The study measured narrative experience and realism in three films from different genres. Results demonstrate that transportability, and both external realism and narrative realism positively influence at least one aspect of narrative experience, and that narrative experience in turn is a significant predictor for enjoyment.

We explored the influence of negation on cognitive dynamics, measured using mouse‐movement trajectories, to test the classic notion that negation acts as an operator on linguistic processing. In three experiments, participants verified the truth or falsity of simple statements, and we tracked the computer‐mouse trajectories of their responses. Sentences expressing these facts sometimes contained a negation. Such negated statements could be true (e.g., “elephants are not small”) or false (e.g., “elephants are not large”). In the first experiment, as predicted by (...) the classic notion of negation, we found that negation caused more discreteness in the mouse trajectory of a response. The second experiment induced a simple context for these statements, yet negation still increased discreteness in trajectories. A third experiment enhanced the pragmatic context of sentences, and the discreteness was substantially diminished, with one primary measure no longer significantly showing increased discreteness at all. Traditional linguistic theories predict rapid shifts in cognitive dynamics occur due to the nature of negation: It is an operator that reverses the truth or falsity of an interpretation. We argue that these results support both propositional and contextual accounts of negation present in the literature, suggesting that contextual factors are crucial for determining the kind of cognitive dynamics displayed. We conclude by drawing broader lessons about theories of cognition from the case of negation. (shrink)

The question of whether time is its own best representation is explored. Though there is theoretical debate between proponents of internal models and embedded cognition proponents (e.g. Brooks R 1991 Artificial Intelligence 47 139–59) concerning whether the world is its own best model, proponents of internal models are often content to let time be its own best representation. This happens via the time update of the model that simply allows the model’s state to evolve along with the state of the (...) modeled domain. I argue that this is neither necessary nor advisable. I show that this is not necessary by describing how internal modeling approaches can be generalized to schemes that explicitly represent time by maintaining trajectory estimates rather than state estimates. Though there are a variety of ways this could be done, I illustrate the proposal with a scheme that combines filtering, smoothing and prediction to maintain an estimate of the modeled domain’s trajectory over time. I show that letting time be its own representation is not advisable by showing how trajectory estimation schemes can provide accounts of temporal illusions, such as apparent motion, that pose serious difficulties for any scheme that lets time be its own representation.

In 1996, the Land and Water Fund of the Rockies (LAW Fund), a nonprofit environmental lawand policy center based in Boulder, Colorado, released How the West Can Win: A Blueprint for a Clean and Affordable Energy Future.

b>: The problem of how physical systems, such as brains, come to represent themselves as subjects in an objective world is addressed. I develop an account of the requirements for this ability that draws on and refines work in a philosophical tradition that runs from Kant through Peter Strawson to Gareth Evans. The basic idea is that the ability to represent oneself as a subject in a world whose existence is independent of oneself involves the ability to represent space, and (...) in particular, to represent oneself as one object among others in an objective spatial realm. In parallel, I provide an account of how this ability, and the mechanisms that support it, are realized neurobiologically. This aspect of the article draws on, and refines, work done in the neurobiology and psychology of egocentric and allocentric spatial representation. (shrink)
