This commentary proposes that “cognitive control” is neither componential nor emergent, but a fundamental feature of behavior. The term “control” requires an operational definition. This is best provided by the negative feedback loop that utilizes behavior to control perception; it does not control behavior per se. In order to model complex cognitive control, Perceptual Control Theory proposes that loops are organized into a dissociable hierarchical network (PCT; Powers, Clark, & McFarland, 1960; Powers, 1973a, 2008). In this way, behavior is dynamically (...) adaptive to environmental disturbances, rather than being formed by, or superimposed upon, learned associations between stimulus and response. (shrink)

The Covid-19 crisis has clarified the demand for an ultra-brief single-session, online, theory-led, empirically supported, psychological intervention for managing stress and improving well-being, especially for people within organizational settings. We designed and delivered “4Ds for Dealing with Distress” during the crisis to address this need. 4Ds unifies a spectrum of familiar emotion regulation strategies, resilience exercises, and problem-solving approaches using perceptual control theory and distils them into a simple four-component rubric. In essence, the aim is to reduce distress and restore (...) wellbeing, both in the present moment through current actions, and through expressing longer-term goal conflicts to discover new perspectives that arise spontaneously after sufficient time and consideration. The intervention is user-led in that it draws on users’ own idiosyncratic and pre-existing experiences, knowledge, skills and resources to help them apply an approach, or combination of approaches, that are proportionate and timed to the nature and context of the stress they are experiencing. In this article we review the empirical basis of the approach within experimental, social, biological and clinical psychology, illustrate the novel and time-efficient delivery format, describe its relevance to sports and exercise, summarise feedback from the recipients of the intervention to date, and describe the directions for future evaluation.

The Interdisciplinary Handbook of Perceptual Control Theory brings together the latest research, theory, and applications from W. T. Powers' Perceptual Control Theory (PCT) that proposes that the behavior of a living organism lies in the control of perceived aspects of both itself and its environment. Sections cover theory, the application of PCT to a broad range of disciplines, why perceptual control is fundamental to understanding human nature, a new way to do research on brain processes and behavior, how the role (...) of natural selection in behavior can be demystified, how engineers can emulate human purposeful behavior in robots, and much more. Each chapter includes an author biography to set the context of their work within the development of PCT. Presents case studies that show how PCT can be applied in different disciplines Illustrates the Test for the Controlled Variable (TCV) and the construction of functional models as fruitful alternatives to mainstream experimental design when studying behavior Shows how theory illuminates structure and functions in brain anatomy Compares and contrasts PCT with other contemporary, interdisciplinary theories.

Research studies have identified various different mechanisms in the effects of nature engagement on well-being and mental health. However, rarely are multiple pathways examined in the same study and little use has been made of first-hand, experiential accounts through interviews. Therefore, a semi-structured interview was conducted with seven female students who identified the role of nature engagement in their well-being and mental health. After applying thematic analysis, 11 themes were extracted from the data set, which were: “enjoying the different sensory (...) input,” “calm nature facilitates a calm mood,” “enhancing decision making and forming action plans,” “enhancing efficiency and productivity,” “alleviating pressure from society's expectations regarding education,” “formation of community relations,” “nature puts things into perspective,” “liking the contrast from the urban environment,” “feel freedom,” “coping mechanism,” and “anxious if prevented or restricted.” The results indicate complementary mechanisms for how nature-related activities benefit mental health and well-being that may occupy different levels of experience within a hierarchical framework informed by perceptual control theory.

The business of cognitive therapy is to transform meanings. What better way to achieve this than through a metaphor? Metaphors straddle two different domains at once, providing a conceptual bridge from a problematic interpretation to a fresh new perspective that can cast one's experiences in a new light. Even the simplest metaphor can be used again and again with different clients, yet still achieve the desired effect. This book is the first to show just how metaphors can be used productively (...) in CBT as an integral part of the treatment. It describes the use of metaphors for a wide range of problems, including anxiety and depression, and provides countless examples of metaphors that have been used by others in CBT. It brings together in one place hundreds of metaphors that experienced therapists have used to great success. It will be a valuable sourcebook for all cognitive behaviour therapists, as well as those training in CBT. (shrink)

ObjectivesThis paper aims to identify potential areas for refinement in existing theoretical models of suicide, and introduce a new integrative theoretical framework for understanding suicide, that could inform such refinements.MethodsLiterature on existing theoretical models of suicide and how they contribute to understanding psychological processes involved in suicide was evaluated in a narrative review. This involved identifying psychological processes associated with suicide. Current understanding of these processes is discussed, and suggestions for integration of the existing literature are offered.ResultsExisting approaches to understanding (...) suicide have advanced the current knowledge of suicide in various ways. They have guided valuable research in the following areas: motivations for suicide and the psychological distress which influences suicide attempts; ambivalence about suicide; suicidal individuals’ focus of attention; and ways in which individuals who contemplate suicide differ from individuals who attempt suicide. We outline a new theoretical framework as a means to integrating all of these concepts into the three principles of control, conflict, and awareness. Within this framework, suicide is regarded as occurring due to a long standing conflict between an individual’s personal goals, culminating in an episode of acute loss of control. The new framework posits that the individual then strives to regain control through the means of suicide because of a narrowed awareness of consequences of their actions on other valued goals. This psychological mechanism of limited awareness is posited to be the common pathway by which individuals make a suicide attempt, regardless of which risk factors are present.ConclusionThis article introduces a theoretical framework that generates several hypotheses for future research, and focuses on psychological processes occurring during immediate crisis. One of the key hypotheses resulting from our predictions on how individuals progress from contemplating to attempting suicide will be tested in an ongoing program of research: Individuals who attempt suicide have a significantly reduced awareness of consequences of suicide, which would negatively impact on their important life goals, values, principles, or ideals, compared to individuals who contemplate suicide. Therapy guided by the new framework may be more flexible, immediate, and client-focused than other therapies for suicidal individuals. (shrink)

Building relationships is crucial for satisfaction and success, especially when entering new social contexts. In the present paper, we investigate whether attempting to improve others’ feelings helps people to make connections in new networks. In Study 1, a social network study following new networks of people for a twelve-week period indicated that use of interpersonal emotion regulation (IER) strategies predicted growth in popularity, as indicated by other network members’ reports of spending time with the person, in work and non-work interactions. (...) In Study 2, linguistic analysis of the tweets from over 8000 Twitter users from formation of their accounts revealed that use of IER predicted greater popularity in terms of the number of followers gained. However, not all types of IER had positive effects. Behavioral IER strategies (which use behavior to reassure or comfort in order to regulate affect) were associated with greater popularity, while cognitive strategies (which change a person’s thoughts about his or her situation or feelings in order to regulate affect) were negatively associated with popularity. Our findings have implications for our understanding of how new relationships are formed, highlighting the important the role played by intentional emotion regulatory processes. (shrink)

Hobbes’s account of the individual’s right to resist sovereign authority is nuanced. His allowance for cases in which a sovereign’s command falls outside the terms of the social contract, despite recent reappraisals, cannot rescue him from the accusation that his system is contradictory. It has been suggested that some Hobbesian rights can be transferred whilst others are quarantined, or that it is the institution of law, rather than the particular commands of the sovereign, which Hobbes ultimately upholds. By reconsidering Hobbes’s (...) concept of sovereignty alongside his theory of natural law, I argue that his system remains in tension with itself. Hobbes’s prioritisation of sovereign judgement over that of the individual, when combined with the principles he retains from the natural law tradition, renders his theory of resistance irreconcilable with his position on sovereignty.

The Epicurean philosophical system has enjoyed much recent scrutiny, but the question of its philosophical ancestry remains largely neglected. It has often been thought that Epicurus owed only his physical theory of atomism to the fifth-century BC philosopher Democritus, but this study finds that there is much in his ethical thought which can be traced to Democritus. It also finds important influences on Epicurus in Democritus' fourth-century followers such as Anaxarchus and Pyrrho, and in Epicurus' disagreements with his own Democritean (...) teacher Nausiphanes. The result is not only a fascinating reconstruction of a lost tradition, but also an important contribution to the philosophical interpretation of Epicureanism, bearing especially on its ideal of tranquillity and on the relation of ethics to physics.

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

In this article, I show how Bruschi’s Le matérialisme politique de Louis Althusser offers, against all attempts conjure up a self-generating general theory of history, a reconstruction of Althusser’s work that shows how its systematicity relies upon the unfinished, incomplete and provisional character of scientific research, always subject to constant rectification. I then claim that, from the conceptualisa-tion of the reproduction of the mode of production as dependent upon the singularity of the con-juncture, to the theorisation of the encounter as (...) the source of historical necessity, this constant re-working is crucial to Althusser’s ability to grasp the reality of class struggle.

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions (...) are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed. (shrink)

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism (...) as a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

This book is the first extensive treatment of Husserl's phenomenology of time-consciousness. Nicolas de Warren uses detailed analysis of texts by Husserl, some only recently published in German, to examine Husserl's treatment of time-consciousness and its significance for his conception of subjectivity. He traces the development of Husserl's thinking on the problem of time from Franz Brentano's descriptive psychology, and situates it in the framework of his transcendental project as a whole. Particular discussions include the significance of time-consciousness for (...) other phenomenological themes: perceptual experience, the imagination, remembrance, self-consciousness, embodiment, and the consciousness of others. The result is an illuminating exploration of how and why Husserl considered the question of time-consciousness to be the most difficult, yet also the most central, of all the challenges facing his unique philosophical enterprise"--Provided by publisher.

Astbury's role in the X-ray study of DNA; his failure to continue his pioneering appraisal; surprising details of his MRC grant application; and his disinterest in Beighton's DNA photographs demand attention. Rosie Franklin's later involvement and behaviour receive comments, which, as with Astbury, are based on personal knowledge.

Writings by a thinker—a psychiatrist, a philosopher, a cybernetician, and a poet—whose ideas about mind and brain were far ahead of his time. Warren S. McCulloch was an original thinker, in many respects far ahead of his time. McCulloch, who was a psychiatrist, a philosopher, a teacher, a mathematician, and a poet, termed his work “experimental epistemology.” He said, “There is one answer, only one, toward which I've groped for thirty years: to find out how brains work.” Embodiments of (...) Mind, first published more than fifty years ago, teems with intriguing concepts about the mind/brain that are highly relevant to recent developments in neuroscience and neural networks. It includes two classic papers coauthored with Walter Pitts, one of which applies Boolean algebra to neurons considered as gates, and the other of which shows the kind of nervous circuitry that could be used in perceiving universals. These first models are part of the basis of artificial intelligence. Chapters range from “What Is a Number, that a Man May Know It, and a Man, that He May Know a Number,” and “Why the Mind Is in the Head,” to “What the Frog's Eye Tells the Frog's Brain” (with Jerome Lettvin, Humberto Maturana, and Walter Pitts), “Machines that Think and Want,” and “A Logical Calculus of the Ideas Immanent in Nervous Activity” (with Walter Pitts). Embodiments of Mind concludes with a selection of McCulloch's poems and sonnets. This reissued edition offers a new foreword and a biographical essay by McCulloch's one-time research assistant, the neuroscientist and computer scientist Michael Arbib. (shrink)

Frederick Soddy's contributions to fundamental aspects of atomic physics are well known. His foresight on questions of atomic, i.e. nuclear, energy have frequently been quoted, and his early concern for the social responsibilities of science and scientists has received comment. Less widely appreciated have been his many publications expounding basic weaknesses in the economic-financial system of the Western world. This paper brings together, mostly in the form of direct quotations from Soddy's many books, an overview of the insights he expressed (...) on these topics. The dates associated with his statements provide the bases for claiming their prophetic status. (shrink)

This book challenges the usual introductions to the study of law. It argues that law is inherently political and reflects the interests of the few even while presenting itself as neutral. It considers law as ideology and as politics, and critically assesses its contribution to the creation and maintenance of a globalised and capitalist world. The clarity of the arguments is admirably suited to provoking discussions of the role of law in our contemporary world. The third edition provides contemporary examples (...) to sustain the arguments in their relevance to the 21st century. The book includes an analysis of the common sense of law; the use of anthropological examples to gain external perspectives of our use and understanding of law; a consideration of central legal concepts, such as order, rules, property, dispute resolution, legitimation and the rule of law; an examination of the role of law in women's subordination; and finally a critique of the effect of our understanding of law upon the wider world. This book is ideal for undergraduate and postgraduate students reading law. (shrink)

Warren Quinn was widely regarded as a moral philosopher of remarkable talent. This collection of his most important contributions to moral philosophy and the philosophy of action has been edited for publication by Philippa Foot. Quinn laid out the foundations for an anti-utilitarian moral philosophy that was critical of much contemporary work in ethics, such as the anti-realism of Gilbert Harman and the neo-subjectivism of Bernard Williams. Quinn's own distinctive moral theory is developed in the discussion of substantial, practical (...) moral issues. For example, there are important pieces here on the permissibility of abortion, the justification of punishing criminals when no particular good seems likely to result, and on the distinction between killing and allowing to die, a distinction crucial to the subject of euthanasia and other topics in medical ethics. The volume would be ideally suited to upper-level undergraduate courses and graduate seminars on the foundations of ethics. (shrink)

This paper distinguishes four senses of naturalism: reductive physicalism; a naturalism that departs from what Thompson calls “natural-historical judgments”; a naturalism that recognizes that physical nature is located within the space of reasons; and a phenomenological naturalism that shifts the focus to the “natural” experiences of subjects who encounter the world. The paper argues for a “phenomenological neo-Aristotelianism” that accounts both for the internal justification of our first-order moral experience and the need for a broader grounding in a universalistic account (...) of the goods of agency.

This article draws on the moral philosophy of Immanuel Kant to explore whether a corporate ‘duty of beneficence’ to non-shareholders is consistent with the orthodox ‘shareholder theory’ of the firm. It examines the ethical framework of Milton Friedman’s argument and asks whether it necessarily rules out the well-being of non-shareholders as a corporate objective. The article examines Kant’s distinction between ‘duties of right’ and ‘duties of virtue’ (the latter including the duty of beneficence) and investigates their consistency with the shareholder (...) theory. The article concludes that it is possible within the ethical framework of shareholder theory for managers to pursue directly the happiness of non-shareholders. Furthermore, shareholders have a duty to hold management to account for the moral consequences of the firm’s activities on non-shareholding stakeholders. (shrink)

"Ashby includes the great thinkers and periods that have shaped Western ethics: the Greeks, the Hebrew prophets, the Roman Stoics, St. Augustine, the medieval ethicists, the Renaissance and Reformation, the Enlightenment, the Romantics, and the radical revolutions of the late nineteenth and early twentieth centuries. In the period from 1850 to 1920, Ashby notes, the transformations wrought by the four great modern thinkers - Darwim, Marx, Nietzsche, and Freud - both extended and significantly challenged the traditional core beliefs of the (...) West and, as a result, bestowed upon us a profound moral crisis, one that we have not yet successfully met. Consequently, as we stand at the brink of the twenty-first century, with its further technological breakthroughs and social upheavals, how will we deal with the moral uncertainties that await us? In his final chapter Ashby contends that while remaining alive to our Western ethical heritage, we will have no choice but to confront its basic presuppositions as we move into a more pluralistic society, for he asserts that the ideology of the future cannot be exclusively Western; future history cannot be purely Western history. So, while this history of ethics cannot tell us how to live, it can offer to the reader what is prerequisite to a more satisfying life: an insightful and inclusive history of where our own ethical beliefs have come from and a sense of the challenges that await us all.".

This book evaluates the consequences of economic, social, environmental and cultural change on people living and working within Teesside in the North-East of England. It assesses the lived experiences, working lives, health and cultural perspectives of residents and key stakeholders in the wake of serious de-industralisation in the region. The narrative is embedded within the long-term industrial history of Stockton: an area once dominated by steel, coal and chemical industries. This past still continues to shape its future and influences the (...) ways in which that future is conceived and envisioned. The author explores a 'biography of place' analytical framework to offer a holistic view of the area, which considers the interaction between the social, economic, cultural, visual and environmental legacy of the community, which is firmly grounded in the past, present and future prospects of those who live and work there.

The role of paleontology in evolutionary biology between the publication of The Origin of Species in 1859 and the Evolutionary Synthesis of the 1940s is frequently described as mostly misguided failure. However, a significant number of American and British PDPS invertebrate paleontologists of this period did devote considerable attention to evolution, and their evolutionary theories and conclusions were a good deal more diverse and nuanced than previous histories have suggested. This paper brings into focus a number of important but underrecognized (...) aspects of the history of paleontology within the history of biology, including that PDPS paleontologists were not all as theoretically backward as they have been portrayed; that the post-Synthesis narrative of the history of evolution should be continually reevaluated, in part to decouple historical understanding from the agendas of authors who have used history to advance particular views of evolution; and that there is a much richer story to be told about the history of evolutionary biology in both the pre- and post-Synthesis eras.
