Short-term or working memory provides temporary storage of information in the brain after an experience and is associated with conscious awareness. Neurons sensitive to the multiple stimulus attributes comprising an experience are distributed within many brain regions. Such distributed cell assemblies, activated by an event, are the most plausible system to represent the WM of that event. Studies with a variety of imaging technologies have implicated widespread brain regions in the mediation of WM for different categories of information. Each kind (...) of WM may thus be expected to involve many brain regions rather than a local, uniquely dedicated set of cells. Neurons in a distributed “cell assembly” may be self-selected by their temporally coherent activations. The process by which this fragmented representation of the recent past is reassembled to accomplish essentially automatic and reliable recognition of a recurrent event constitutes an important problem. One plausible mechanism to achieve the identification of past with previous events would require that the representational system mediating WM must coexist in spatial extent and somehow overlap in temporal activation with cell ensembles registering input from subsequent events. The detection of such a postulated mechanism required an experimental approach which would focus upon spatial patterns of coherent activation while information about different events was stored in WM and retrieved, rather than focusing upon the temporal sequences of activation in localized regions of interest. For this purpose, the familiar delayed matching from sample task was modified. A series of information-free flashes, or “noncontingent probes,” was presented before an initial series of visual information items, the Priming Sample, which were to be held in WM during a Delay Period. A second series of visual information items were then presented, the Matching Sample. The task required detection of any item in the second series which had beenabsentfrom the initial series. Thirty such trials with a particular category of visual information constituted a single task. Several DMS tasks with this standardized design, but with different categories of visual information, were presented within each test session. The information categories included letters of the alphabet, single digit numbers, or faces from a school yearbook. Event-related potentials , were computed from 21 standardized electrode placements, separately for information-free probes and for information items in each interval of the trials within a task. Because each electrode is particularly sensitive to coherent activation of neurons in the immediately underlying brain regions, topographic maps were constructed and interpolated across the surface of the scalp. The momentary fluctuations of the resulting voltage “landscapes” throughout the task were then subjected to quantitative analysis. Distinctive landscapes sometimes persisted for prolonged periods, implying sustained engagement of very large populations of neurons. “Difference landscapes” were constructed by subtraction of topographic maps evoked by noncontingent probes during the Delay Period from maps of probe ERPs before the presentation of the initial information in the Priming Sample. Such probe difference landscapes displayed recurrent high similarity to momentary landscapes elicited during subsequent presentation of the information items in the Matching Sample. It seemed as if the distributed cell assembly continuously engaged by mediation of WM of the diverse attributes of the initial stimuli was being dynamically compared to the ensembles engaged by registration of the subsequent stimuli. Spatial Principal Component Analysis was applied to the sequences of momentary voltage landscapes observed throughout trials of each task. This method sought a small number of spatial patterns with which these large sets of inhomogeneous spatial distributions of voltage could be reconstructed. This is the spatial analog of the reconstruction of local ERPs by temporal principal components, as often described previously. Five Spatial Principal Components were found which accounted for about 90% of the total variance of voltage across the surface of the scalp throughout every task. Theloadings,or distinguishing topographic features, of these SPCs, were highly similar during every cognitive task for every subject. However,factor scores,or relative average contribution to the overall voltage distributions, of the different SPCs varied substantially among subjects between the tasks and momentarily within successive intervals of each task. These five SPCs may reflect coherent activation of huge distributed ensembles of neurons which comprise independent but interacting functional brain subsystems. These subsystems may correspond to basic resources available to individuals for allocation to mediate conscious evaluation of information during cognitive activity, providing a filter to bind together fractionated representations of the past to evaluate the present.

People consistently act in ways that harm the environment, even when believing their actions are environmentally friendly. A case in point is a biased judgment termed the negative footprint illusion, which arises when people believe that the addition of “eco-friendly” items to conventional items, reduces the total carbon footprint of the whole item-set, whereas the carbon footprint is, in fact, increased because eco-friendly items still contribute to the overall carbon footprint. Previous research suggests this illusion is the manifestation of (...) an “averaging-bias.” We present two studies that explore whether people’s susceptibility to the negative footprint illusion is associated with individual differences in: environment-specific reasoning dispositions measured in terms of compensatory green beliefs and environmental concerns; or general analytic reasoning dispositions measured in terms of actively open-minded thinking, avoidance of impulsivity and reflective reasoning. A negative footprint illusion was demonstrated when participants rated the carbon footprint of conventional buildings combined with eco-friendly buildings and conventional cars combined with eco-friendly cars. However, the illusion was not identified in participants’ ratings of the carbon footprint of apples. In Studies 1 and 2, environment-specific dispositions were found to be unrelated to the negative footprint illusion. Regarding reflective thinking dispositions, reduced susceptibility to the negative footprint illusion was only associated with actively open-minded thinking measured on a 7-item scale and 17-item scale. Our findings provide partial support for the existence of a negative footprint illusion and reveal a role of individual variation in reflective reasoning dispositions in accounting for a limited element of differential susceptibility to this illusion.

Objectives: The objective of this post hoc exploratory analysis was to examine the relationship between age and measures of cortical excitability and inhibition. Methods: Forty-six participants (24 with major depressive disorder and 22 healthy controls) completed MT, SICI, ICF, and CSP testing in a cross-sectional protocol. Of these 46 participants, 33 completed LICI testing. Multiple linear robust regression and Spearman partial correlation coefficient were used to examine the relationship between age and the TMS measures. Results: In the overall sample (...) of 46 participants, age had a significant negative relationship with motor threshold in both the right (rs = -0.49, adjusted p =.007; β= -0.08, adjusted p=.001) and left (rs = -0.42, adjusted p =.029; β= -0.05, adjusted p=.004) hemispheres. This significant negative relationship of age with motor threshold was also observed in the sample of depressed youth in both the right (rs = -0.70, adjusted p =.002; β= -0.09, adjusted p=.001) and left (rs = -0.54, adjusted p =.034; β= -0.05, adjusted p=.017) hemispheres, but not in healthy controls. In the sample of the 33 participants who completed LICI testing, age had a significant negative relationship with LICI (200 millisecond interval) in both the right (rs = -0.48, adjusted p =.05; β= -0.24, adjusted p=.007) and left (rs = -0.64, adjusted p =.002; β= -0.23, adjusted p=.001) hemispheres. This negative relationship between age and LICI (200 millisecond interval) was also observed in depressed youth in both the right (rs = -0.76, adjusted p =.034; β= -0.35, adjusted p=.004) and left (rs = -0.92, adjusted p =.002; β= -0.25, adjusted p=.001) hemispheres. Conclusion: These findings suggest that younger children have higher motor thresholds. This is more pronounced in depressed youth than healthy controls. LICI inhibition may also increase with age in youth. (shrink)

Measuring neuronal activity with electrophysiological methods may be useful in detecting neurological dysfunctions, such as mild traumatic brain injury (mTBI). This approach may be particularly valuable for rapid detection in at-risk populations including military service members and athletes. Electrophysiological methods, such as quantitative electroencephalography (qEEG) and recording event-related potentials (ERPs) may be promising; however, the field is nascent and significant controversy exists on the efficacy and accuracy of the approaches as diagnostic tools. For example, the specific measures derived from an (...) electroencephalogram (EEG) that are most suitable as markers of dysfunction have not been clearly established. A study was conducted to summarize and evaluate the statistical rigor of evidence on the overall utility of qEEG as an mTBI detection tool. The analysis evaluated qEEG measures/parameters that may be most suitable as fieldable diagnostic tools, identified other types of EEG measures and analysis methods of promise, recommended specific measures and analysis methods for further development as mTBI detection tools, identified research gaps in the field, and recommended future research and development thrust areas. The qEEG study group formed the following conclusions: 1. Individual qEEG measures provide limited diagnostic utility for mTBI. However, many measures can be important features of qEEG discriminant functions, which do show significant promise as mTBI detection tools. 2. ERPs offer utility in mTBI detection. In fact, evidence indicates that ERPs can identify abnormalities in cases where EEGs alone are nondisclosing. 3. The standard mathematical procedures used in the characterization of mTBI EEGs should be expanded to incorporate newer methods of analysis including nonlinear dynamical analysis, complexity measures, analysis of causal interactions, graph theory and information dynamics. 4. and 5. are too long to include here.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

In the exploratory study reported here, we tested the efficacy of an intervention designed to train teenagers with Möbius syndrome (MS) to increase the use of alternative communication strategies (e.g., gestures) to compensate for their lack of facial expressivity. Specifically, we expected the intervention to increase the level of rapport experienced in social interactions by our participants. In addition, we aimed to identify the mechanisms responsible for any such increase in rapport. In the study, five teenagers with MS interacted with (...) three naïve participants without MS before the intervention, and with three different naïve participants without MS after the intervention. Rapport was assessed by self-report and by behavioral coders who rated videos of the interactions. Individual non-verbal behavior was assessed via behavioral coders, whereas verbal behavior was automatically extracted from the sound files. Alignment was assessed using cross recurrence quantification analysis and mixed-effects models. The results showed that observer-coded rapport was greater after the intervention, whereas self-reported rapport did not change significantly. Observer-coded gesture and expressivity increased in participants with and without MS, whereas overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact non-verbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment. (shrink)

This paper synthesizes convergent lines of evidence to evaluate the hypothesis that objective falsity is essential to lying. Objective accounts of lying affirm this hypothesis; subjective accounts deny it. Evidence from history, logic, social observation, popular culture, lexicography, developmental psychology, inference, spontaneous description, and behavioral experimentation strongly supports the hypothesis. Studies show that the only apparent evidence against the hypothesis is due to task substitution, i.e. ethical concerns or perspective-taking interfering with performance on categorization tasks. I conclude that, overall, (...) existing evidence decisively favors objective accounts. (shrink)

We consider the varieties and directions of influence that the source and target domains involved in a conceptual metaphor can have on each other during the course of understanding metaphorical utterances based on the metaphor. Previous studies have been restricted both as to direction of influence and as to type of influence. They have been largely confined to the “forward” (source to target) direction of influence, and they have concentrated on the transfer of features or propositions and (to some extent) (...) the highlighting of aspects of a domain. By contrast, this article stresses the importance both of other varieties of influence (e.g., transfer of queries and uncertainty effects) and of “reverse” influence (target to source). We seek to curb the natural tendency to think that, because metaphor involves an overall move from source to target, therefore all inter-domain influences in the course of understanding go in that direction. The bulk of the article explores the theoretical issues involved. These issues have arisen out of a reasoning-based approach to metaphor, seeking to make best use of information from metaphorical utterance, context, source and target domains, and known metaphorical mappings, by applying a complex overall reasoning process. The article briefly explains the thorough implementation of reverse influence in a computer program for metaphorical reasoning called ATT-Meta, although the theoretical considerations are relevant to all disciplines concerned with metaphor. We make some suggestions for further computational and psychological research on metaphor. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:15 LOCKE, HUME AND THE NATURE OF VOLITIONS 1. The concept of a volition plays a key role in the theories of mind that both Locke and Hume devise. It is central to the views each develops on the nature of action and of explanations of actions, on the character of practical reasoning, on the nature of desire, on the ways in which, most usefully, to categorize the several (...) kinds of mental states and events. Without attending closely to their concepts of volition, one cannot get quite clear about the views of each, and the considerations thought to support those views, on the vexed questions of free action and of responsibility. Whether it be Locke or Hume, then, there is good reason to scrutinize what he says of volitions. Why take them together? The principal reason is that the views of each, when considered closely, throw a quite considerable light on those of the other (or so I hope to show). But there is a philosophical point as well. A theory of volitions more adequate than either proposes must borrow from each. What is amenable to being borrowed, and what ought to be borrowed, are fairly readily seen when the two theories are put face to face. I concentrate on three central issues: the question whether volitions are thoughts; the relationship of volition to practical reasoning; the links between volitions and their effects. Hume's views on these topics are to be found chiefly in the Treatise and the first Enquiry; Locke's, of course, in the Essay. Locke's recently published correspondence with the Dutch theologian Philippus van Limborch is, however, essential reading here, and I have made extensive use of it. 16 2. Locke and Hume agree that volitions are indefinable psychological primitives that must be invoked in an analysis of voluntary action (T 399, EHU 69, E 249). They agree, too, in a number of the things that each says in his efforts to characterize volitions. They differ, however, on a fundamental point, Hume's volitions are 'internal impression[s]' (T 399); Locke's are 'thought[s] of the Mind' (E 235). As internal impressions Humean volitions are feelings akin to, but not 'properly speaking' (T 399) instances of, passions. They are like the 'direct passions' (desire and aversion, grief and joy, hope and fear) in two respects: they are 'immediate effects of pain and pleasure' (T 399); they are 'propense and averse motions of the mind' (T 574), and thus bear a special relation to action. Though they are not thoughts they have causal, thus contingent, links to thoughts, including in particular thoughts whose content specify the so-called 'immediate object of volition' (E 66). As 'distinct impression[s]' (T 625) volitions do not modify the thoughts of their objects in the logically intimate way in which, in Hume's view, the feeling essential to belief 'modiffies] the conception' (T 625) of what is believed. Hume frequently compares volitions to commands (T 623, 629, 632; EHU 48, 64, 65, 67, 68). He also, not surprisingly, denies them truth values: because they are not capable of 'an agreement or disagreement either to the real relations of ideas, or to real existence and matter of fact' it is 'impossible... they can be pronounced either true or false' (T 458; compare T 415). Locke's volitions are thoughts, not feelings; and they have their own contents and objects. '[T]he proper and only object of the will', he writes, 'is some action of ours' (E 258); in forming a volition one 17 'wills to number', say, or 'wills to walk' (C 405). Locke never says as much, but his overall theory is best read as requiring volitions to be thoughts without truth values. He contrasts 'Will' or 'the Power of Volition1 with 'Understanding' or 'the Power of Thinking' (E 128). Since 'Volition' is as much a 'Mode... £f thinking' as is 'Reasoning' or 'Judging' (E 227), however, the contrast is most plausibly taken as one between thoughts that do and thoughts that do not purport to represent the way the world is. Locke's distinction, to be examined below, between volitions and 'last judgements of the understanding' suggests the... (shrink)

During balanced growth of cells in culture all extensive properties of the culture — e.g. cell number, total mass, total DNA content — increase exponentially at the same specific growth rate. Therefore, in some average sense, each component of a cell must double between birth and division. For DNA there exists an elaborate mechanism to ensure precise replication of the genetic material and accurate partitioning of identical copies of the genome to the two daughter cells. Do cells possess another mechanism (...) that intentionally relates the timing of cell division to overall increase in cell size, or is the coordination of growth and division an incidental consequence of size‐independent rules for progress through the cell cycle?.

The Palgrave Handbook of Practical Animal Ethics is a recent addition to anthologies in the field, joining The Oxford Handbook of Animal Ethics, and The Routledge Handbook of Animal Ethics. Edited by Andrew Linzey and Clair Linzey of the Oxford Centre for Animal Ethics, the book boasts more than 30 contributors, many of them philosophers, but also including sociologists, scientists, theologians, lawyers, psychologists, and animal advocates. The editors were intentionally multidisciplinary in their approach, noting that “there is currently no book (...) series that is a focus for multidisciplinary research in the field,” and calling attention to the need not only for philosophical inquiry into what we owe animals, but also into the “social, legal, cultural, religious and political” influences that “legitimate animal abuse” (p. viii).The book is divided up into four sections: “The Ethics of Control,” “The Ethics of Captivity,” “The Ethics of Killing,” and “The Ethics of Causing Suffering.” Each of these sections includes an editorial introduction and multiple entries spanning diverse issues, including animal research, animal agriculture, hunting, fishing, zoos, the role of animals in religion, the role of language in structuring thought about nonhuman animals, and others. Similarly, the chapters span issues affecting many species, including farmed animals, fish, deer, elephants, whales and dolphins, rodents, companion animals (e.g., dogs and cats), and others.While the book is billed as a “practical” handbook of animal ethics, it does wade into some conceptual territory, tackling such issues as the ethical permissibility of confining and controlling animals, the question of whether (painless) death harms nonhuman animals, and the comparative wrongness of killing humans and nonhuman animals. This said, it largely stays away from more detailed discussion of normative ethical theory and the moral standing of nonhuman animals, focusing instead on the specific ways that humans treat nonhuman animals. In focusing more on practical than theoretical ethics, the Palgrave Handbook of Practical Animal Ethics both complements and differentiates itself from some other anthologies in the field.The book has several strengths to recommend it, the first being the logic of its organization. The ethically problematic aspects of humans’ treatment of nonhuman animals frequently map onto one or more of the categories of causing suffering, killing, and confining. The organization of chapters under these section headings helps to provide a rational structure to the text, as well as an easy way for the reader to navigate which sections they would like to tackle first (although there is some overlap between sections). With this, the explicit and sustained focus on the ethics of control (section 1) is a welcome and differentiating feature of the text. Much prior work in animal ethics has addressed questions of harming and killing animals, but the ethical permissibility of control per se has received comparatively lesser attention.The multidisciplinary nature of the book is also a selling point. In any anthology on animal ethics, the reader can expect entries from academic philosophers, but the book's inclusion of empirical scientific reviews, sociological and legal analyses, and work in discourse analysis are strengths. One danger in focusing exclusively on what we ought to think and do is that it ignores the influences on how we actually think and act. Many of the book's entries address these influences and thus round out the normative analysis.The middle two sections of the book seem most successful to this reviewer. The section on the ethics of killing contains two well-argued conceptual chapters, coupled with practical analyses of fishing, deer hunting, and religious perspectives on killing nonhuman animals. While animal research and animal agriculture are not directly addressed in this section, the conceptual arguments can be applied to the killing of nonhuman animals in these contexts. The section on the ethics of captivity is not as conceptually strong but contains excellent empirical chapters on the welfare of elephants, whales, and dolphins in captivity. Prior work in normative ethics has established how confinement can be harmful to nonhuman animals by directly causing suffering or depriving them of opportunities for satisfaction (see, e.g., DeGrazia, 2002). However, it is important to complement such theoretical frameworks with substantiation of how captivity actually is harmful to nonhuman animals in virtue of the interests they have and how captivity infringes upon such interests. These chapters argue that captivity is fundamentally (and not conditionally) incompatible with the welfare of elephants, whales, and dolphins.If I have one criticism of the book, it is that it could be stronger on certain conceptual issues. Acknowledging its practical and not theoretical focus, it is nonetheless true that if controlling, confining, killing, and causing suffering to nonhuman animals is wrong, then it is important to say something about why it is wrong—even if that explanation amounts to a short synopsis of more theoretical work done elsewhere. While the question of killing is addressed well, the section on the ethics of causing suffering does not address directly why (or under what conditions) causing suffering is wrong. The chapters in this section are worthwhile reading and review practices causing animal suffering in a variety of contexts. Nonetheless, some additional conceptual front matter would have strengthened the section overall.From a conceptual standpoint, the sections on the ethics of control and captivity seem to hang together. Confinement is a form of control and might be argued against on the grounds that it deprives nonhuman animals of opportunities for satisfaction, directly causes physical injury, or causes psychological distress, anxiety, or boredom. These kinds of arguments fit into interest-based accounts of animal welfare, which in turn can be subsumed under a principle of nonmaleficence: We should not cause harm to animals under some specified set of conditions; confinement harms animals in ways x, y, or z; therefore, we should not confine animals in this way.While such interest-based arguments do make an appearance in the text, several of the book's authors also elaborate an autonomy-based argument against control and confinement: Nonhuman animals have their own kind of autonomy, and just as infringing upon the autonomy of paradigmatic persons is wrong, infringing upon nonhuman animals’ autonomy is also wrong. The problem with this argument is that different kinds of autonomy are likely to be at stake. The wrongness of infringing upon paradigmatic persons’ autonomy is often explained by the facts that we are self-conscious, capable of abstract thought (including language use), and capable of intentionally choosing the kind of life that we want to live (e.g., relating to long-term projects or schemes of personal ethics). It could be argued that because nonhuman animals are not capable of exercising this kind of autonomy, they therefore cannot be harmed by its infringement.Some of the book's authors chip away at this presumption, noting (inter alia) that nonhuman animals have desires to move around and do things that are thwarted by confinement or control, that these desires constitute a form of agency, and that (following previous scholarship) nonhuman animals possess some forms of self-awareness. Specifically, the chapters from Valéry Giroux and Carl Saucier-Bouffard, Lori Gruen, and Carlos Naconecy consider such arguments. Naconecy draws upon David DeGrazia's (2009) analysis of animal self-awareness in making his argument. Though the issue deserves more treatment than I can give it here, it seems that nonhuman animals’ autonomy and self-awareness, even if granted, are of a different sort than that possessed by paradigmatic persons. Specifically, (most) nonhuman animals cannot feel wronged by having their preferences overridden because they are not the kinds of beings who are capable of abstractly considering themselves as autonomous and worthy of self-direction. They may desire things, and thwarting these desires might sometimes harm them, but that is a different kind of argument.Infringing upon nonhuman animals’ (more limited kind of) autonomy might nonetheless be wrong, but if different sorts of autonomy are at stake, then moral arguments relating to paradigmatic persons cannot be directly transposed to nonhuman animals. Some additional argument(s) must be supplied, but (on my reading) the book's contributors stop short of this. Nonetheless, as stated above, the ethics of control and questions of nonhuman animals’ autonomy are not as well trod as other issues in animal ethics. Despite my taking issue with some of the details, the discussions contained in the book's first two sections are worthy reading and help to advance the field.Overall, the book's chapters are well written and cogently argued, and given its breadth, different readers will find different things to value in it. The Palgrave Handbook of Practical Animal Ethics is a welcome addition to the literature. (shrink)

Teaching about homosexuality, especially in a positive light, has long been held to be a controversial issue. There is, however, a view of the capacity for reason that finds that those who deem homosexuality to be controversial will ultimately contradict themselves, becoming unreasonable. By this standard of reason, homosexuality should be treated as non controversial in schools. In this essay, John Petrovic argues that this epistemic position is problematic. Instead, he defends a Deweyan epistemology that casts reason as, in (...) part, a set of socially acquired habits of mind. People who have been socialized into heterosexist habits of mind must be exposed to counterhegemonic discourses. One such discourse can be found in the public values of liberal democracy through which the practice of reason must be pursued. Petrovic discusses the practical guidance provided by assuming a view of normative reason versus habituated reason in terms of both pedagogy and curriculum. (shrink)

In this article we consider the material dimensions of schooling as constitutive of the possibilities inherent in “fixing” education. We begin by mapping out the problem of “fixing education,” pointing to the necrophilic tendencies of contemporary education—a desire to kill what otherwise might be life-giving. In this sense, to “fix” education is to make otherwise fluid processes-of-living static. We next point to the material realities of this move to fix. After establishing the material consequences of perpetually fixing schools, we provide (...) a brief overview of two critical perspectives that might be shown as attempts to “unfix” education: critical pedagogy and unschooling. Though both offer critiques of normative education, these approaches are also bound by their failure to fully engage with the material dimensions of schooling. As such, both critical pedagogy and unschooling inadvertently cut off key possibilities for human flourishing within educational environments. In their rush to “unfix”—to counter the necrophilic tendencies of contemporary education—these approaches exclude or otherwise foreclose upon resistive challenges to the normative order that extend from the margins. In response, we turn to the possibilities for unschooling within the materially public spaces of schools. These are the spaces where fixity fails—possibility extends from unschooling in schools, from unfixing the process of fixing education. We end by considering the possibilities inherent in Community Service Learning as a valuable means to engage in a radically public, and unfixed, educational system. (shrink)

This interview with John Cottingham explores some major themes in his recent work in moral philosophy and the philosophy of religion. It begins by discussing his views on the task of philosophy and focuses particularly on philosophy’s role in achieving an overall view of the world and for understanding and achieving the good life. It also discusses some ‘limits of philosophy’ with respect to understanding and achieving the good life; i.e., some ways in which philosophical reflection on the (...) good life needs to draw on insights found in other domains such as psychoanalysis and religious faith and spiritual practice. The role of philosophy and spiritual practice in coming to religious faith and supporting it is also discussed. (shrink)

The overall goal of this essay is to explore the initial findings of neuroscientific research on meditation; in doing so, the essay also suggests potential avenues of further inquiry. The essay consists of three sections that, while integral to the essay as a whole, may also be read independently. The first section, “Defining Meditation,” notes the need for a more precise understanding of meditation as a scientific explanandum. Arguing for the importance of distinguishing the particularities of various traditions, the (...) section presents the theory of meditation from the paradigmatic perspective of Buddhism, and it discusses the difficulties encountered when working with such theories. The section includes an overview of three practices that have been the subject of research, and it.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:15 LOCKE, HUME AND THE NATURE OF VOLITIONS 1. The concept of a volition plays a key role in the theories of mind that both Locke and Hume devise. It is central to the views each develops on the nature of action and of explanations of actions, on the character of practical reasoning, on the nature of desire, on the ways in which, most usefully, to categorize the several (...) kinds of mental states and events. Without attending closely to their concepts of volition, one cannot get quite clear about the views of each, and the considerations thought to support those views, on the vexed questions of free action and of responsibility. Whether it be Locke or Hume, then, there is good reason to scrutinize what he says of volitions. Why take them together? The principal reason is that the views of each, when considered closely, throw a quite considerable light on those of the other (or so I hope to show). But there is a philosophical point as well. A theory of volitions more adequate than either proposes must borrow from each. What is amenable to being borrowed, and what ought to be borrowed, are fairly readily seen when the two theories are put face to face. I concentrate on three central issues: the question whether volitions are thoughts; the relationship of volition to practical reasoning; the links between volitions and their effects. Hume's views on these topics are to be found chiefly in the Treatise and the first Enquiry; Locke's, of course, in the Essay. Locke's recently published correspondence with the Dutch theologian Philippus van Limborch is, however, essential reading here, and I have made extensive use of it. 16 2. Locke and Hume agree that volitions are indefinable psychological primitives that must be invoked in an analysis of voluntary action (T 399, EHU 69, E 249). They agree, too, in a number of the things that each says in his efforts to characterize volitions. They differ, however, on a fundamental point, Hume's volitions are 'internal impression[s]' (T 399); Locke's are 'thought[s] of the Mind' (E 235). As internal impressions Humean volitions are feelings akin to, but not 'properly speaking' (T 399) instances of, passions. They are like the 'direct passions' (desire and aversion, grief and joy, hope and fear) in two respects: they are 'immediate effects of pain and pleasure' (T 399); they are 'propense and averse motions of the mind' (T 574), and thus bear a special relation to action. Though they are not thoughts they have causal, thus contingent, links to thoughts, including in particular thoughts whose content specify the so-called 'immediate object of volition' (E 66). As 'distinct impression[s]' (T 625) volitions do not modify the thoughts of their objects in the logically intimate way in which, in Hume's view, the feeling essential to belief 'modiffies] the conception' (T 625) of what is believed. Hume frequently compares volitions to commands (T 623, 629, 632; EHU 48, 64, 65, 67, 68). He also, not surprisingly, denies them truth values: because they are not capable of 'an agreement or disagreement either to the real relations of ideas, or to real existence and matter of fact' it is 'impossible... they can be pronounced either true or false' (T 458; compare T 415). Locke's volitions are thoughts, not feelings; and they have their own contents and objects. '[T]he proper and only object of the will', he writes, 'is some action of ours' (E 258); in forming a volition one 17 'wills to number', say, or 'wills to walk' (C 405). Locke never says as much, but his overall theory is best read as requiring volitions to be thoughts without truth values. He contrasts 'Will' or 'the Power of Volition1 with 'Understanding' or 'the Power of Thinking' (E 128). Since 'Volition' is as much a 'Mode... £f thinking' as is 'Reasoning' or 'Judging' (E 227), however, the contrast is most plausibly taken as one between thoughts that do and thoughts that do not purport to represent the way the world is. Locke's distinction, to be examined below, between volitions and 'last judgements of the understanding' suggests the... (shrink)

Establishes the importance of Husserl's phenomenology for Levinas's ethics.

As a work of a scholarship it seems to me to compare favourably with the best books on the subject, including those by Marcus Singer and Onora Nell.' Prof.

In the first comprehensive biography of Ferdinand de Saussure, John E. Joseph restores the full character and history of a man who is considered the founder of modern linguistics and whose ideas have influenced literary theory, philosophy, cultural studies, and virtually every other branch of humanities and the social sciences.

This book, first published in 1990, takes a critical look at the major assumptions which support critical thinking programs and discovers many unresolved questions which threaten their viability. John McPeck argues that some of these assumptions are incoherent or run counter to common sense, while others are unsupported by the available empirical evidence. This title will be of interest to students of the philosophy of education.

Is morality too difficult for human beings? Kant said that it was, except with God's assistance. Contemporary moral philosophers have usually discussed the question without reference to Christian doctrine, and have either diminished the moral demand, exaggerated human moral capacity, or tried to find a substitute in nature for God's assistance. This book looks at these philosophers--from Kant and Kierkegaard to Swinburne, Russell, and R.M. Hare--and the alternative in Christianity.

Examines Arthur Schopenhauer's (1788-1860) conception of human agency and responsibility, his unique ethics of the morally virtuous character, and his assessment of life as fundamentally suffering. This title focuses on his contention that the human will and the human body cannot have a cause and effect relationship with each other.

This article summarizes a variety of current as well as previous research in support of a new theory of consciousness. Evidence has been steadily accumulating that information about a stimulus complex is distributed to many neuronal populations dispersed throughout the brain and is represented by the departure from randomness of the temporal pattern of neural discharges within these large ensembles. Zero phase lag synchronization occurs between discharges of neurons in different brain regions and is enhanced by presentation of stimuli. This (...) evidence further suggests that spatiotemporal patterns of coherence, which have been identified by spatial principal component analysis, may encode a multidimensional representation of a present or past event. How such distributed information is integrated into a holistic percept constitutes the binding problem. How a percept defined by a spatial distribution of nonrandomness can be subjectively experienced constitutes the problem of consciousness. Explanations based on a discrete connectionistic network cannot be reconciled with the relevant facts. Evidence is presented herein of invariant features of brain electrical activity found to change reversibly with loss and return of consciousness in a study of 176 patients anesthetized during surgical procedures. A review of relevant research areas, as well as the anesthesia data, leads to a postulation that consciousness is a property of quantumlike processes, within a brain field resonating within a core of structures, which may be the neural substrate of consciousness. This core includes regions of the prefrontal cortex, the frontal cortex, the pre- and paracentral cortex, thalamus, limbic system, and basal ganglia. (shrink)

If one is an egalitarian, what should one want to equalize? Opportunities or outcomes? Resources or welfare? These positions are usually conceived to be very different. I argue in this paper that the distinction is misconceived: the only coherent conception of resource equality implies welfare equality, in an appropriately abstract description of the problem. In this section, I motivate the program which the rest of the paper carries out.

This work is an exploration of divine command theory, which is the theory that what makes something morally obligatory is that God commands it.
