This paper continues joint work of the authors with P. Clote, R. Soare and S. Wainer (Annals of Pure and Applied Logic, vol. 31 (1986), pp. 145--163). An element x of the Cantor space 2 ω is said have rank α in the closed set P if x is in $D^\alpha(P)\backslash D^{\alpha + 1}(P)$ , where D α is the iterated Cantor-Bendixson derivative. The rank of x is defined to be the least α such that x has rank α in (...) some Π 0 1 set. The main result of the five-author paper is that for any recursive ordinal λ + n (where λ is a limit and n is finite), there is a point with rank λ + n which is Turing equivalent to O (λ + 2n) . All ranked points constructed in that paper are Π 0 2 singletons. We now construct a ranked point which is not a Π 0 2 singleton. In the previous paper the points of high rank were also of high hyperarithmetic degree. We now construct ▵ 0 2 points with arbitrarily high rank. We also show that every nonrecursive RE point is Turing equivalent to an RE point of rank one and that every nonrecursive ▵ 0 2 point is Turing equivalent to a hyperimmune point of rank one. We relate Clote's notion of the height of a Π 0 1 singleton in the Baire space with the notion of rank. Finally, we show that every hyperimmune point x is Turing equivalent to a point which is not ranked. (shrink)

Kant starts the Groundwork of the Metaphysics of Morals by emphasizing the importance of separating the a priori or rational part of moral philosophy from the a posteriori or empirical aspects. Indeed, he reserves the term moral philosophy for the rational part. He writes ‘ethics … the empirical part might be given the special title practical anthropology, the term moral philosophy being properly used to refer just to the rational part’. Throughout his writings in both theoretical and practical philosophy the (...) distinction between what is a priori and what is a posteriori is given paramount importance. We need to separate that which has its source a priori from its application to, for example human beings. (shrink)

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)

... there are cases in which on the basis of a temporally extended content of consciousness a unitary apprehension takes place which is spread out over a temporal interval (the so-called specious present). ... That several successive tones yield a melody is possible only in this way, that the succession of psychical processes are united "forthwith" in a common structure.

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)

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, brain activations, and corresponding (...) perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (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)

In evolutionary medicine, researchers characterize some outcomes as evolutionary mismatch. Mismatch problems arise as the result of organisms living in environments to which they are poorly adapted, typically as the result of some rapid environmental change. Depression, anxiety, obesity, myopia, insomnia, breast cancer, dental problems, and numerous other negative health outcomes have all been characterized as mismatch problems. The exact nature of evolutionary mismatch itself is unclear, however. This leads to a lack of clarity about the sorts of problems that (...) evolutionary mismatch can actually explain. Resolving this challenge is important not only for the evolutionary health literature, but also because the notion of evolutionary mismatch involves central concepts in evolutionary biology: fitness, evolution in changing environments, and so forth. In this paper, I examine two characterizations of mismatch currently in the literature. I propose that we conceptualize mismatch as a relation between an optimal environment and an actual environment. Given an organism and its particular physiology, the optimal environment is the environment in which the organism’s fitness is maximized: in other words, the optimal environment is that in which the organism’s fitness is as high as it can possibly be. The actual environment is the environment in which the organism actually finds itself. To the extent that there is a discordance between the organism’s actual and optimal environments, there is an evolutionary mismatch. In the paper, I show that this account of mismatch gives us the right result when other accounts fail, and provides useful targets for investigation. (shrink)

This article outlines the main tenets of affect theory and links these to Sloterdijk’s spherology. Where affect foregrounds prepersonal energies and posthuman impulses, spherology provides a lens for considering how humans congregate in constantly reconfiguring socialities in their pursuit of legitimacy and immunity. The article then explores the relevance of “affective spheres” for contemporary social science research. The article’s main argument here is that research of contemporary organisational and professional practices must increasingly be spherogenic, or seeking to build “affective spheres.” (...) The basis of this argument are the in situ complexity and fast-changing nature of practices, and the increasing challenges involved in objectifying or ‘freezing’, and analysing or dissecting such practices. The article draws for its case study on a video-reflexive project conducted in a U.S. health service. The article concludes that the notion of research as spherogenics counterbalances the conventional methodological emphasis on a predetermined stance —whether neutral or political—in our construction and enactment of social science research.

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.

Profinite groups are Galois groups. The effective study of infinite Galois groups was initiated by Metakides and Nerode [8] and further developed by LaRoche [5]. In this paper we study profinite groups without considering Galois extensions of fields. The Artin method of representing a finite group as a Galois group has been generalized by Waterhouse [14] to profinite groups. Thus, there is no loss of relevance in our approach.The fundamental notions of a co-r.e. profinite group, recursively profinite group, and the (...) degree of a co-r.e. profinite group are defined in §1. In this section we prove that every co-r.e. profinite group can be effectively represented as an inverse limit of finite groups. The degree invariant is shown to behave very well with respect to open subgroups and quotients. The work done in this section is basic to the rest of the paper.The commutator subgroup, the Frattini subgroup, thep-Sylow subgroups, and the center of a profinite group are essential in the study of profinite groups. It is only natural to ask if these subgroups are effective. The following question exemplifies our approach to this problem: Is the center a co-r.e. profinite group? Theorem 2 provides a general method for answering this type of question negatively. Examples 3,4 and 5 are all applications of this theorem. (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)

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.

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.

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)

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)

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. The blueprint found that rapid growth in the West would lead to another round of fossil fuel–fired power plants and the associated environmental impacts unless policy makers changed course toward a more sustainable energy future. The study provided a set of strategies that lawmakers, (...) regulators, and other stakeholders could use to help implement such a course change. It is concluded that the blueprint’s recommendations are even more salient than they were 5 years ago. The article leads off with an overview of changes in the electric industry over the past 5 years in the interior West and concludes with a review of the executive summary of the LAW Fund’s 1996 report, the policy directives of which remain valid today.

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.

Within natural language semantics, pronouns are often thought to correspond to variables whose values are contributed by contextual assignment functions. This paper concerns the application of this idea to cases where the antecedent of a pronoun is a plural quantifiers. The paper discusses the modelling of accessibility patterns of quantifier antecedents in a dynamic theory of interpretation. The goal is to reach a semantics of quantificational dependency which yields a fully semantic notion of pronominal accessibility. I argue that certain dependency (...) phenomena that arise in quantificationally created contexts require a representation of context wherein the labelling of antecedents is not rigid but rather dynamic itself. I propose a stack-based alternative to classic assignment functions, along the lines of Vermeulen (1993) and van Eijck (2001), and give a dynamic semantics of quantification which correctly accommodates the problematic anaphoric phenomena.

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.

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.
