The rotating spot method of timing subjective events involves the subject’s watching a rotating spot on a computer and reporting the position of the spot at the instant when the subjective event of interest occurs. We conducted an experiment to investigate factors that may impact on the results produced by this method, using the subject’s perception of when they made a simple finger movement as the subjective event to be timed. Seven aspects of the rotating spot method were investigated, using (...) a factorial experiment. Four of these aspects altered the physical characteristics of the computer generated spot or clock face and the remaining three altered the instructions given to the participant. We found compelling evidence that one factor, whether the subject was instructed to report the instant when the finger movement was initiated or the instant when it was completed, resulted in a systematic shift in the response. Evidence that three other factors affect the observed variability in the response was also found. In addition, we observed that there are substantial systematic differences in the responses made by different subjects. We discuss the implications of our findings and make recommendations about the optimal way of conducting future experiments using the rotating spot method. Our overall conclusion is that our results strongly validate the rotating spot method of timing at least the studied variety of subjective event. (shrink)

Exploring the Illusion of Free Will and Moral Responsibility is an edited collection of new essays by an internationally recognized line-up of contributors. It is aimed at readers who wish to explore the philosophical and scientific arguments for free will skepticism and their implications.

Leading scholars continue the debate over whether consciousness causes behavior or plays no functional role in it, discussing the question in terms of neuroscience, philosophy, law, and public policy.

Power density spectra and phase synchrony measurements were taken from intracranial electrode grids implanted in epileptic subjects. Comparisons were made between data from the waking state and from the period of unconsciousness immediately following a generalised tonic–clonic seizure. Power spectra in the waking state resembled coloured noise. Power spectra in the unconscious state resembled coloured noise from 1 to about 5 Hz, but at higher frequencies changed in two out of three subjects to resemble white noise. This boosted unconscious gamma (...) power to a higher level than conscious gamma power. For both gamma and beta passbands, synchrony measurements showed more widespread phase synchrony in the unconscious than the conscious state. We conclude that neither gamma activity per se nor phase synchrony per se are neural correlates of consciousness. (shrink)

The original data reported by Benjamin Libet and colleagues are reinterpreted, taking into account the facilitation which is experimentally demonstrated in the first of their series of articles. It is shown that the original data equally well or better support a quite different set of conclusions from those drawn by Libet. The new conclusions are that it takes only 80 ms for stimuli to come to consciousness and that “subjective back-referral of sensations in time” to the time of the stimulus (...) does not occur.

The duration of “now” is shown to be important not only for an understanding of how conscious beings sense duration, but also for the validity of the phenomenological enterprise as Husserl conceived it. If “now” is too short, experiences can not be described before they become memories, which can be considered to be transcendent rather than immanent phenomena and therefore inadmissible as phenomenological data. Evidence concerning (a) the objective duration of sensations in various sensory modalities, (b) the time necessary for (...) sensations to enter consciousness and (c) the variability in the subjective sense of time's passing under different conditions is used to conclude that the duration of “now” can actually vary under normal conditions from about 10 ms to several seconds and in extreme cases up to several hours. Thus the immanent moment can be long enough to encompass a report of the contents of consciousness, making phenomenology a viable project. A further speculation from the evidence described is that consciousness takes discrete samples of the external world, at a rate inversely proportional to the duration of the “now” moment. (shrink)

The first priority of this response is to address Libet's rebuttal of my reinterpretation of his data. Then, because many authors have commented on various aspects of the debate, the rest of the response is organized in terms of subject matter, not as replies to each individual commentator. First, I reply to an objection expressed by two separate commentators to part of my reinterpretation of those of Libet's data supposedly supporting backward referral. This leads to a brief discussion of the (...) whole concept of backward referral. The relevance of the flash-lag illusion to possible measurement errors in the Libet/Trevena and Miller paradigm is addressed next. Finally, I have a few words to say on the relationship between quantum mechanical ontology and free will. (shrink)

The author's version of the electromagnetic field theory of consciousness is stated briefly and then three difficulties with the theory are discussed. The first is a purely technical problem: how to measure accurately enough the spatial properties of the fields which are proposed to be conscious and then how to generate these artificially, so that the theory can be tested. The second difficulty might also be merely technical, or it might be substantive and fatal to the theory. This is that (...) present measurements seem to show a non-constant relationship between brain-generated electromagnetic fields and sensation. The third difficulty involves the basic question of whether consciousness per se has any direct effect on the brain. As an afterword, the disproportionate contribution of synchronously firing neurons to conscious percepts is simply explained in terms of the electromagnetic field theory of consciousness.

Empirical work is reviewed which correlates the presence or absence of various parts of the auditory evoked potential with the disappearance and reemergence of auditory sensation during induction of and recovery from anesthesia. As a result, the hypothesis is generated that the electrophysiological correlate of auditory sensation is whatever neural activity generates the middle latency waves of the auditory evoked potential. This activity occurs from 20 to 80 ms poststimulus in the primary and secondary areas of the auditory cortex. Evidence (...) is presented suggesting that earlier or later waves in the auditory evoked potential do not covary with auditory sensation (as opposed to auditory perception) and it is therefore suggested that they are possibly not the electrophysiological correlates of sensation.

The electromagnetic field theory of consciousness proposes that conscious experiences are identical with certain electromagnetic patterns generated by the brain. While the theory has always acknowledged that not all of the electromagnetic patterns generated by brain activity are conscious, until now it has not been able to specify what might distinguish conscious patterns from non-conscious patterns. Here a hypothesis is proposed about the 3D shape of electromagnetic fields that are conscious, as opposed to those that are not conscious. Seven predictions (...) arising from this hypothesis are described. Existing empirical evidence shows that four of these predictions have already been successfully tested. Requirements for experimental testing of the other three are discussed. (shrink)

Continuing the debate over whether consciousness causes behaviour or plays no functional role in it, leading scholars discuss the question in terms of neuroscience, philosophy, law, and public policy.

Evidence is summarised for and against the hypothesis that potentiation or facilitation of neural responses during a train of threshold-level stimuli occurred in the experiments reported by Libet et al. . It is concluded that such potentiation probably did occur. Since the main arguments for the existence of subjective backwards referral take it as given that such potentiation did not occur, it is further concluded that the main arguments for the existence of subjective backwards referral fail.

In a provocative article published in the Journal of Consciousness Studies, Susan Pockett argues for the plausibility of considering consciousness as an epiphenomenon of neural activity. This means that consciousness, though caused by the brain, would not in its turn have any role in the causation of neural activity and, consequently, of behaviour. Critical for her argument is the distinction she makes between 'consciousness per se' and 'the neural processing that accompanies it' . In her discussion, though, the (...) author begs the question concerning whether there really is such 'consciousness itself, as distinct from the neural processing that goes with it' . If consciousness as it exists happens not to be distinct from some sort of neural processing, then Pockett's 'consciousness per se' has no causal effect simply because it does not exist. (shrink)

In this “Reply” paper, the arguments and experimental findings by Pockett, Pollen, and Haggard et al. are analyzed. It had been shown that a 0.5 s duration of repetitive activations of sensory cortex is required to produce a threshold of sensation. The view that this is due to a facilitatory buildup in excitatory state to finally elicit neuronal firing is shown to be incompatible with several lines of evidence. Objections to the phenomenon of subjective referral backwards in time are (...) also untenable. Haggard, Cartledge, Dafydd, and Oakley report that a self-initiated act can, under hypnotic suggestion, appear to the subject to be “involuntary.” The act under hypnosis is better viewed as one initiated unconsciously, not as an act of conscious will.

Susan Pockett presents sound arguments supporting her reinterpretations of data that Libet and co-workers used to support a number of intriguing and influential conclusions regarding the microgenesis and timing of conscious sensory experience and volitionally controlled motor responses. The following analysis, extending and elaborating some of her main arguments, proposes that Libet's experimental methodologies and rationales, and thus also his interpretation of data, are flawed and that neglect or ignorance of methodological and empirical constraints well known to sensory (...) psychologists risks drawing premature or faulty conclusions about the timing of conscious experience.

According to transhumanists who urge the radical enhancement of human beings, humanity’s top priority should be engineering “posthumans,” whose features would include agelessness. Increasingly, transhumanism is critiqued on foundational grounds rather than based largely on anticipated results of its implementation, such as rising social inequality. This expansion is crucial but insufficient because, despite its radical aim, transhumanism reflects beliefs and attitudes that are evident in the broader culture. With a focus on the yearning to eliminate aging, I consider four of (...) these: a disproportionate reliance on science and technology to address major human challenges; the conceptualization of human beings in terms of binaries like “young-old”; a repudiation of vulnerability; and intensifying perfectionism. Illuminating these interlocked commitments both deepens an existing critique of transhumanism and draws our attention to deleterious cultural views that must be vigorously contested if our commitment to human flourishing is to be deep and unwavering.

The book is an investigation of the semantics of numericals, counting and measuring, and its connection to the mass/count distinction from a theoretical and crosslinguistic perspective. It reviews some recent major linguistic results in these topics, and presents the author's new research including in-depth case studies of a number of typologically unrelated languages.

A nativist moral psychology, modeled on the successes of theoretical linguistics, provides the best framework for explaining the acquisition of moral capacities and the diversity of moral judgment across the species. After a brief presentation of a poverty of the moral stimulus argument, this chapter sketches a view according to which a so-called Universal Moral Grammar provides a set of parameterizable principles whose specific values are set by the child's environment, resulting in the acquisition of a moral idiolect. The principles (...) and parameters approach predicts moral diversity, but does not entail moral relativism. (shrink)

Reading Feminist Theory: From Modernity to Postmodernity interweaves classical and contemporary writings from the social sciences and the humanities to represent feminist thought from the late eighteenth century to the present. Editors Susan Archer Mann and Ashly Suzanne Patterson pay close attention to the multiplicity and diversity of feminist voices, visions, and vantage points by race, class, gender, sexuality, and global location. Along with more conventional forms of theorizing, this anthology points to multiple sites of theory production--both inside and (...) outside of the academy--and includes personal narratives, poems, short stories, zines, and even music lyrics. Offering a truly global perspective, the book devotes three chapters and more than thirty readings to the topics of colonialism, imperialism and globalization. It also provides extensive coverage of third-wave feminism, poststructuralism, queer theory, postcolonial theory, and transnational feminisms. (shrink)

If you're woke, you're left. If you're left, you're woke. We blur the terms, assuming that if you're one you must be the other. That, Susan Neiman argues, is a dangerous mistake. The intellectual roots and resources of wokeism conflict with ideas that have guided the left for more than 200 years: a commitment to universalism, a firm distinction between justice and power, and a belief in the possibility of progress. Without these ideas, Neiman argues, they will continue to (...) undermine their own goals and drift, inexorably and unintentionally, towards the right. In the long run, they risk becoming what they despise. One of the world's leading philosophical voices, Neiman makes this case by tracing the malign influence of two titans of twentieth-century thought, Michel Foucault and Carl Schmitt, whose work undermined ideas of justice and progress and portrayed social life as an eternal struggle of us against them. A generation schooled with these voices in their heads, raised in a broader culture shaped by the ruthless ideas of neoliberalism and evolutionary psychology, has set about changing the world. It's time they thought again. (shrink)

A unique and interdisciplinary collection in which scholars from Philosophy join those from Film Studies, English, and Comparative Literature to explore the nature and limits of love through in-depth reflection on particular works of literature and film.

This original and authoritative book offers a first-ever attempt to define a poetics of the editing arts. It proposes a new field of editing studies, in which the 'ideal editor' can be understood in relation to the long-theorised author and reader. The book's premise is that editing, like other forms of 'making', is mostly invisible and can only be brought into full view through a comparative analysis that includes the insights of practitioners. The argument, laid down in careful layers, is (...) supported by a panoramic historical narrative that tracks the shifts in textual authority from religious and secular institutions to the romanticised self of the digital present. The dangers posed by the anti-editing rhetoric of this hybrid romanticism are confronted head-on. To the traditional perception of editing as the imposition of closure, A Poetics of Editing adds a perspective on a dynamic process with a sense of the possible. (shrink)

Presented as a diary of a year-long search, this book explores Sabbath-keeping from the point of view of a doubting Jew trying to make sense of what has become a quaint, obsolete practice. Although the book relies upon centuries of philosophical thought, it is accessible, direct, and often humorous, aimed at others who, like Susan Pashman, cannot blindly 'obey, ' but who demand a sensible basis for their practices. Remember the Sabbath and keep it holy. What does this mean? (...) And why is it a moral obligation, ranked high on a list of commandments that includes refraining from murder, lying, cursing, and picturing God? Ultimately, Dr. Pashman decides that 'stepping back' to an objective position--the starting point for moral conduct--is the detachment that Sabbath observance demands. A Sabbath properly observed is not just a day to unplug from technology; it is a day to attentively contemplate the lives and needs of others, to take a 'God's eye' view of the world. From time to time, the journey is paused for brief personal memoirs of Pashman's Sabbath experiences over the years. These poignant, often hilarious glimpses into her life before this quest introduce the reader to her atheist grandfather, her observant Uncle Wolfie, her sly mother-in-law, her cynical older son, and her younger son whose own children, she hopes, will continue engaging with Jewish traditions. Filled with wisdom and much humor, this is a book for both contemporary, skeptical Jews seeking to preserve personal autonomy while continuing family traditions, and also for those 'spiritual seekers' of all religions in search of the rootedness that tradition supplies, without having to engage in what they might regard as hypocrisy.

Antisthenes was famous in antiquity for his studies of Homer's poems, his affiliation with Gorgias and the sophistic movement, his pure Attic writing style, and his inspiration of Diogenes of Sinope, who founded the Cynic philosophical movement. Antisthenes stands at two of the greatest turning points in ancient intellectual history: from pre-Socraticism to Socraticism, and from classical Athens to the Hellenistic period. Antisthenes' works form the path to a better understanding of the intellectual culture of Athens that shaped Plato and (...) laid the foundations for Hellenistic philosophy and literature. Antisthenes of Athens keeps in mind the goals and polemics framing each philosophical and textual discussion. The volume considers the ancient traditions about Antisthenes' rejection of Plato's “Theory of Forms,” his assertion of the paradox, “It is impossible to gainsay,” and his denial that definition of essence is possible, as well as the plausible intentions of Antisthenes. In cases where these questions are not easily settled, and where modern interpretation has varied, Susan H. Prince identifies the roots of the disagreements. The goal and meaning of Antisthenes' other famous ancient paradox, “I would rather go mad than have pleasure,” is illuminated by comparison with other evidence showing that pleasure does have a place in his ideology. Evidence for his relationship to Diogenes of Sinope, and for his receptions by the Cynics, Stoics, Skeptics, Christians, and Neo-Pagans is examined for both its historical value and its distorting tendencies.

This illuminating Research Handbook analyses the role that emotions play and ought to play in legal reasoning and practice, rejecting the simplistic distinction between reason and emotion. International expert contributors take multidisciplinary approaches, drawing on neuroscience, philosophy, literary theory, psychology, history, and sociology to examine the role of a wide range of emotions across a variety of legal contexts. Chapters consider how the rich tapestry of human emotion impacts legal actors, influences legal doctrine, and shapes the dynamics of legal institutions. (...) Moving beyond legal contexts traditionally considered rife with emotion such as the criminal law and jury trials, the Handbook explores how emotion relates to contracts, property, bankruptcy, international law, and truth and reconciliation commissions. It also reflects on the importance of research methodologies, theories, and techniques for assessing the role of emotion in the legal arena. Surveying the depth and complexity of law and emotion across a panoply of legal actions, institutional contexts, and legal doctrines, this Research Handbook will be critical reading for academics and students of legal theory and legal philosophy. Its detailed examination of emotions in the practice of private, public, international, and criminal law will also be beneficial for lawyers, judges, and policymakers. (shrink)

Have you ever gotten chills while listening to a particularly gorgeous piece of music? Or felt a sense of calm while gazing at a painting of a serene landscape? We have experiences like those every day, but rarely stop to consider what's happening internally to cause them. In Your Brain on Art, founder of the International Arts + Mind Lab at Johns Hopkins University School of Medicine Susan Magsamen and Google designer Ivy Ross explain how, by understanding how we (...) biologically react to aesthetic experiences, we can not only heal as individuals but thrive as communities. Using the new science of neuroaesthetics, which explores our physiological reactions to art, Magsamen and Ross show us how, for instance, gardening can help a person heal from trauma or listening to a major fifth interval can snap the body out of a fight-or-flight response. Beyond enjoyment and abstraction, art can change the way we operate on a daily, practical level. And, in addition to helping each of us heal from stress, anxiety, burnout, and other malaises of modern life, neuroaesthetics can effect major change in society writ large, whether through public art murals in high-crime areas or music and dance therapy for patients experiencing neurodegenerative disorders.

Recent years have seen educationalists turning to Emmanuel Levinas when considering the relationship between ethics and education. While it is true that Levinas never speaks of ethics in relation to the practice of classroom education, nonetheless, for Levinas, ethics is a teaching, and learning can only take place in the presence of the Other. This book considers how, within the constraints of the Irish primary school education system, teachers can develop a Levinasian approach to teaching, that affords both them and (...) the children they teach multiple opportunities throughout the school day to take up their ethical responsibility for each other as Other. Beginning from a Levinasian understanding of learning and teaching as constituting primordially relational and ethical events, and weaving the philosophies of Levinas, and the educationalists he inspires, into the approaches of philosophy with children, restorative practice, and PAX, this book suggests a unique approach to ethics in Irish primary school classrooms. The focus of this thesis, then, is on both the philosophical underpinnings that anchor teaching as a Levinasian, and a consideration of what practical approaches could be employed by the Levinasian teacher.

Only human beings have a rich conceptual repertoire with concepts like tort, entropy, Abelian group, mannerism, icon and deconstruction. How have humans constructed these concepts? And once they have been constructed by adults, how do children acquire them? While primarily focusing on the second question, in The Origin of Concepts , Susan Carey shows that the answers to both overlap substantially. Carey begins by characterizing the innate starting point for conceptual development, namely systems of core cognition. Representations of core (...) cognition are the output of dedicated input analyzers, as with perceptual representations, but these core representations differ from perceptual representations in having more abstract contents and richer functional roles. Carey argues that the key to understanding cognitive development lies in recognizing conceptual discontinuities in which new representational systems emerge that have more expressive power than core cognition and are also incommensurate with core cognition and other earlier representational systems. Finally, Carey fleshes out Quinian bootstrapping, a learning mechanism that has been repeatedly sketched in the literature on the history and philosophy of science. She demonstrates that Quinian bootstrapping is a major mechanism in the construction of new representational resources over the course of childrens cognitive development. Carey shows how developmental cognitive science resolves aspects of long-standing philosophical debates about the existence, nature, content, and format of innate knowledge. She also shows that understanding the processes of conceptual development in children illuminates the historical process by which concepts are constructed, and transforms the way we think about philosophical problems about the nature of concepts and the relations between language and thought.

Sound and Grammar: A Neo-Sapirian Theory of Language by Susan F. Schmerling offers an original overall linguistic theory based on the work of the early American linguist Edward Sapir, supplemented with ideas from the philosopher-logicians Kazimierz Ajdukiewicz and Richard Montague and the linguist Elisabeth Selkirk. The theory yields an improved understanding of interactions among different aspects of linguistic structure, resolving notorious issues directly inherited by current theory from (post- ) Bloomfieldian linguistics. In the theory presented here, syntax is a (...) filter on a phonological algebra, not a linguistic level; linguistic expressions are phonological structures, and syntax is semantically relevant relations among phonological structures. The book shows how Neo-Sapirian grammar sheds new light on syntax-phonology interactions in English, German, French, and Spanish. (shrink)

In this short paper I will introduce an idea which, I will argue, presents a fundamental additional challenge to the machine consciousness community. The idea takes the questions surrounding phenomenology, qualia and phenomenality one step further into the realm of intersubjectivity but with a twist, and the twist is this: that an agent’s intersubjective experience is deeply felt and necessarily co-affective; it is enkinaesthetic, and only through enkinaesthetic awareness can we establish the affective enfolding which enables first the perturbation, and (...) then the balance and counter-balance, the attunement and co-ordination of whole-body interaction through reciprocal adaptation.
