In the Spring of 1944, an informal discussion took place in Cambridge between Mr. R. S. Whipple, Professor Allan Ferguson and Mr. F. H. C. Butler, concerning the formation of a national Society for the History of Science. This is the opening sentence of the inaugural issue of the Bulletin of the British Society for the History of Science, the Society's first official publication. Butler himself was the author of this outline account of the subsequent approach to the Royal (...) Society, the parallel moves to establish a National Committee of the International Academy of the History of Science, the formation of a provisional committee to prepare a draft constitution for a national society, and the proceedings of the first Annual General Meeting in May 1947. Whipple had been in Cambridge to discuss his offer to present his collection of old scientific instruments to the University and the possible foundation of a new museum, and Butler, as Secretary of the History of Science Committee in Cambridge, was the chief mover in both this development and an initiative coupled with it to establish a department of the history of science.

Previously we reported a three-factor structure for hallucinations accompanying sleep paralysis . These earlier analyses were, however, based on retrospective accounts. In a prospective study, 383 individuals reported individual episodes online providing further evidence for the three-factor structure as well as clearer conceptually meaningful relations among factors than retrospective studies. In addition, reports of individual episodes permitted a more fine-grained analysis of the internal structure of factors to assess predictions based on the hypothesis that a sensed or felt presence is (...) a core experience affecting other SP hallucinations. Results were generally consistent with this hypothesis. In particular, associations among, and temporal stability of, sensory hallucinations were largely explained by their common association with FP. The findings are consistent with REM initiation of a threat activated vigilance system with pervasive effects on the SP experience and suggest a potential model for the thematic organization of nightmares and dreams more generally.

Nielsen [Nielsen, T. . Felt presence: Paranoid delusion or hallucinatory social imagery? Consciousness and Cognition, 16, 975–983.] raises a number of issues and presents several provocative arguments worthy of discussion regarding the experience of the felt presence during sleep paralysis . We consider these issues beginning with the nature of FP and its relation to affective-motivational systems and provide an alternative to Nielsen’s reduction of FP to a purely spatial hallucination. We then consider implications of the “normal social imagery” model. (...) We can find only one specific empirical hypothesis articulated within this framework and it turns out to be one that we explicitly addressed in our original paper. We also review our position regarding the possible relation of FP during SP to a number of related anomalous experiences and contrast FP to anomalous vestibular-motor phenomena. We review our position that the neuromatrix concept, in the light of available evidence, is more appropriately applied to V-M experiences than FP. Finally, we pursue speculations, raised in Nielsen’s commentary, on the wider implications of FP. (shrink)

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability (...) and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values. (shrink)

An analytic cognitive style denotes a propensity to set aside highly salient intuitions when engaging in problem solving. We assess the hypothesis that an analytic cognitive style is associated with a history of questioning, altering, and rejecting supernatural claims, both religious and paranormal. In two studies, we examined associations of God beliefs, religious engagement, conventional religious beliefs and paranormal beliefs with performance measures of cognitive ability and analytic cognitive style. An analytic cognitive style negatively predicted both religious and paranormal beliefs (...) when controlling for cognitive ability as well as religious engagement, sex, age, political ideology, and education. Participants more willing to engage in analytic reasoning were less likely to endorse supernatural beliefs. Further, an association between analytic cognitive style and religious engagement was mediated by religious beliefs, suggesting that an analytic cognitive style negatively affects religious engagement via lower acceptance of conventional religious beliefs. Results for types of God belief indicate that the association between an analytic cognitive style and God beliefs is more nuanced than mere acceptance and rejection, but also includes adopting less conventional God beliefs, such as Pantheism or Deism. Our data are consistent with the idea that two people who share the same cognitive ability, education, political ideology, sex, age and level of religious engagement can acquire very different sets of beliefs about the world if they differ in their propensity to think analytically.

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between (...) the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep. (shrink)

Argues that the brain and the mind are one--that the thoughts, feelings, dreams, and memories that constitute our consciousness are in fact an amalgam of electrical impulses and chemical interactions.

Where does consciousness come from and how does it work? Is it a purely biological thing? Where does the brain leave off and the mind begin? These questions, once viewed as ethereal and impossible to study empirically, are now being addressed by science in bold and startling new ways.In Consciousness, world-renowned neuropsychiatrist J. Allan Hobson presents a witty and introspective consideration of this mysterious concept, connecting it to specific areas of the brain and their chemical and physical states. Hobson (...) guides his readers through the various states of waking, dreaming, and nonconsciousness using the theories and data of neuroscience, psychiatry, and neurophysiology. Although his ideas are based in science, his imaginative approach keeps us in touch with the mysterious and seductive nature of his subject.Richly woven, with references to literature, philosophy, and the author's personal experiences, Consciousness is a delightful and compact introduction to a concept central to the human experience.

We examined the affective consequences of everyday attention lapses and memory failures. Significant associations were found between self-report measures of attention lapses , attention-related cognitive errors , and memory failures , on the one hand, and boredom and depression , on the other. Regression analyses confirmed previous findings that the ARCES partially mediates the relation between the MAAS-LO and MFS. Further regression analyses also indicated that the association between the ARCES and BPS was entirely accounted for by the MAAS-LO and (...) MFS, as was that between the ARCES and BDI-II. Structural modeling revealed the associations to be optimally explained by the MAAS-LO and MFS influencing the BPS and BDI-II, contrary to current conceptions of attention and memory problems as consequences of affective dysfunction. A lack of conscious awareness of one’s actions, signaled by the propensity to experience brief lapses of attention and related memory failures, is thus seen as having significant consequences in terms of long-term affective well-being.

What is dreaming, and what causes it? Why are dreams so strange, and why are they so hard to remember? Replacing dream mystique with modern dream science, J. Allan Hobson provides a new and increasingly complete picture of how dreaming is created by the brain. Dreaming explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness. Through an investigation of his own dreams to illustrate (...) and explain some of the fascinating discoveries of modern sleep science, Hobson challenges some of the traditionally accepted theories about the meaning of dreams and reveals why sleep is not just good for health but essential for life.

This paper considers the Cartesian theatre as a metaphor for the virtual reality models that the brain uses to make inferences about the world. This treatment derives from our attempts to understand dreaming and waking consciousness in terms of free energy minimization. The idea here is that the Cartesian theatre is not observed by an internal audience but furnishes a theatre in which fictive narratives and fantasies can be rehearsed and tested against sensory evidence. We suppose the brain is driven (...) by the imperative to infer the causes of its sensory samples; in much the same way as scientists are compelled to test hypotheses about experimental data. This recapitulates Helmholtz's notion of unconscious inference and Gregory's treatment of perception as hypothesis testing. However, we take this further and consider the active sampling of the world as the gathering of confirmatory evidence for hypotheses based on our virtual reality. The ensuing picture of consciousness resolves a number of seemingly hard problems in consciousness research and is internally consistent with current thinking in systems neuroscience and theoretical neurobiology. In this formalism, there is a dualism that distinguishes between the process of inference and the process that entails inference. This separation is reflected by the distinction between beliefs and the physical brain states that encode them. This formal approach allows us to appeal to simple but fundamental theorems in information theory and statistical thermodynamics that dissolve some of the mysterious aspects of consciousness.

Hypnagogic and hypnopompic experiences (HHEs) accompanying sleep paralysis (SP) are often cited as sources of accounts of supernatural nocturnal assaults and paranormal experiences. Descriptions of such experiences are remarkably consistent across time and cultures and consistent also with known mechanisms of REM states. A three-factor structural model of HHEs based on their relations both to cultural narratives and REM neurophysiology is developed and tested with several large samples. One factor, labeled Intruder, consisting of sensed presence, fear, and auditory and visual (...) hallucinations, is conjectured to originate in a hypervigilant state initiated in the midbrain. Another factor, Incubus, comprising pressure on the chest, breathing difficulties, and pain, is attributed to effects of hyperpolarization of motoneurons on perceptions of respiration. These two factors have in common an implied alien ''other'' consistent with occult narratives identified in numerous contemporary and historical cultures. A third factor, labeled Unusual Bodily Experiences, consisting of floating/flying sensations, out-of-body experiences, and feelings of bliss, is related to physically impossible experiences generated by conflicts of endogenous and exogenous activation related to body position, orientation, and movement. Implications of this last factor for understanding of orientational primacy in self-consciousness are considered. Central features of the model developed here are consistent with recent work on hallucinations associated with hypnosis and schizophrenia. (shrink)

The studies reported in the following articles are aimed at providing a comprehensive, detailed, and quantitative picture of cognition in human dreaming. Our main premises are that waking, REM sleep, and non-REM sleep represent physiologically distinct and identifiable brain states and that the differences between waking, REM, and NREM mentation reflect these physiological differences. We have studied dreams at a formal level of analysis and, in these papers, have studied the specific dream properties of emotions, bizarre transformations, scene shifts, and (...) plot coherence, in adults and 4- to 10-year-old children, as part of a larger effort to map state-dependent mental phenomena back onto the varying neurobiological processes that must underlie them. We believe that such efforts will enhance our understanding not only of dreaming and its neurophysiological substrates, but also of the cognitive processes that dreaming shares with other unusual mental states.

A 'sensed presence' often accompanies hypnagogic and hypnopompic hallucinations associated with sleep paralysis. Qualitative descriptions of the sensed presence during sleep paralysis are consistent with the experience of a monitoring, stalking predator. It is argued that the sensed presence during sleep paralysis arises because of REM-related endogenous activation of a hypervigilant and biased attentive state, the normal function of which is to resolve ambiguities inherent in biologically relevant threat cues. Given the lack of disambiguating environmental cues, however, the feeling of (...) presence persists as a protracted experience that is both numinous and ominous. This experience, in turn, shapes the elaboration and integration of the concurrent hallucinations that often take on supernatural and daemonic qualities. The sense of presence considered here is an 'other' that is radically different from, and hence more than a mere projection of, the self. Such a numinous sense of otherness may constitute a primordial core consciousness of the animate and sentient in the world around us. (shrink)

Definitions of dreaming are not required to map formal features of mental activity onto brain measures. While dreaming occurs during all stages of sleep, intense dreaming is largely confined to REM. Forebrain structures and many neurotransmitters can contribute to sleep and dreaming without negating brainstem and aminergic-cholinergic control mechanisms. Reductionism is essential to science and AIM has considerable heuristic value. Recent findings support sleep's role in learning and memory. Emerging technologies may address long-standing issues in sleep and dream research.

Do the most celebrated works of Rousseau—more particularly his Discourse on Inequality, émile , and Control Social —present on the whole a coherent answer to the problems of Education and Society? My impression is that Rousseau has here been very much calumniated, owing to the incredible haste and superficiality with which his writings have generally been studied. Even sympathetic inquirers, like M. Schinz in his thorough and attractive work La Pensée de J. J. Rousseau , seem to be too easily (...) discouraged in the quest for unity. (shrink)

In contrast to the behavioral sciences, the nature and impact of ethical procedures such as informed consent and constraints on the use of deception have been addressed infrequently in the marketing discipline. This article describes an initial investigation into the methodological and ethical practices reported in published marketing research articles since the mid-1970s. Empirical articles appearing in the Journal of Marketing Research and the Journal of Consumer Research between 1975 and 1976, 1989 and 1990, and 1996 and 1997 were coded (...) according to methodological and ethical practices employed and compared with recent trends in the social psychological research literature. The marketing findings revealed an increase over time in laboratory experimentation, the utilization of active deception and debriefing, and the use of university student samples. Although the results suggest that marketing researchers use deception with less frequency and intensity overall than social psychologists, the observed rise in deception procedures in marketing investigations stands in stark contrast to the situation in social psychology, where deception rates have been declining along with a corresponding increase in nonexperimental methodologies and nonstudent samples. The article concludes with a call for greater attention to the ethical, methodological, and disciplinary consequences of the increasing use of deception in marketing research and emphasizes the need for more complete reporting of ethical procedures in published research.

This book provides a multidisciplinary analysis of the potential conflict between a government’s duty to protect children and a parent’ right to raise children in a manner they see fit. Using philosophical, bioethical, and legal analysis, the author engages with key scholars in pediatric decision-making and individual and religious rights theory. Going beyond the parent-child dyad, the author is deeply concerned both with the inteests of the broader society and with the appropriate limits of government interference in the private sphere. (...) The text offers a balance of individual and population interests, maximizing liberty but safeguarding against harm. Bioethics and law professors will therefore be able to use this text for both a foundational overview as well as specific, subject-level analysis. Clinicians such as pediatricians and gynecologists, as well as policy-makers can use this text to achieve balance between these often competing claims. The book is written by a physician with practical and theoretical knowledge of the subject, and deep sympathy for the parental and family perspectives. As such, the book proposes a new way of evaluating parental and state interventions in children's’ healthcare: a refreshing approach and a useful addition to the literature. (shrink)

O idealismo transcendental anunciado por Husserl como idêntico à própria fenomenologia nunca deixou de ser um dos pontos mais polêmicos de sua filosofia. A esse respeito, um dos primeiros críticos da posição filosófica esposada publicamente por Husserl a partir de Ideias para uma fenomenologia pura foi seu outrora aluno Roman Ingarden. Seu denso e resoluto criticismo em relação à perspectiva idealista de Husserl é amparado por minuciosas investigações de ordem ontológica, contidas sobretudo em seu magnum opus, Controvérsia acerca da existência (...) do mundo. Contudo, algumas das discussões aí indicadas já se faziam presentes em seu famoso escrito A obra de arte literária, de 1929. Com efeito, neste texto, que busca demarcar o estatuto ontológico das obras literárias, Ingarden já empreende análises que lhe permitem questionar alguns dos pressupostos centrais ao idealismo transcendental advogado por Husserl. A proposta do presente trabalho é apresentar algumas das noções básicas da ontologia ingardeniana, bem como sua visão acerca do modo de ser da obra literária, e tentar compreender como estes elementos se coordenam a fim de fornecer a Ingarden alguns dos elementos que lhe permitem ensaiar uma resposta realista à perspectiva de Husserl.

While all states in the United States require certain vaccinations for school attendance, all but three allow for religious exemptions to receiving such vaccinations, and 18 allow for exemptions on the basis of other deeply held personal beliefs. The rights of parents to raise children as they see fit may conflict with the duty of the government and society to protect the welfare of children. In the U.S., these conflicts have not been settled in a uniform and consistent manner. We (...) apply a test that provides a concrete and formal rubric to evaluate such conflicts. For some vaccinations, based on the individual medical characteristics of the disease and the risks of being unvaccinated, the test would suggest that permitting conscientious exemptions is ethical. However, for vaccinations protecting against other diseases that are more severe or easily transmitted, the test would suggest that the federal government may ethically impose laws that deny such exemptions.

Opponents of male circumcision have increasingly used human rights positions to articulate their viewpoint. We characterize the meaning of the term “human rights.” We discuss these human rights arguments with special attention to the claims of rights to an open future and to bodily integrity. We offer a three-part test under which a parental decision might be considered an unacceptable violation of a child's right. The test considers the impact of the practice on society, the impact of the practice on (...) the individual, and the likelihood of adverse impact. Infant circumcision is permissible under this test. We conclude that infant circumcision may be proscribed as violating local norms, even though it does not violate human rights. (shrink)

Female genital alteration is any cutting, removal or destruction of any part of the external female genitalia. Various FGA practices are common throughout the world. While most frequent in Africa and Asia, transglobal migration has brought ritual FGA to Western nations. All forms of FGA are generally considered undesirable for medical and ethical reasons when performed on minors. One ritual FGA procedure is the vulvar nick. This is a small laceration to the vulva that does not cause morphological changes. Besides (...) being performed as a primary ritual procedure it has been proposed as a substitute for more extensive forms of FGA. Measures advocated or taken to reduce the burden of FGA can be punitive or non-punitive. Even if it is unethical to perform VN, we argue that it also is unethical to attempt to suppress it through punishment. First, punishment of VN is likely to cause more harm than good overall, even to those ostensibly being protected. Second, punishment is likely to exceed legitimate retributive ends. We do not argue in favor of performing VN. Rather, we argue that non-punitive strategies such as education and harm reduction should be employed. (shrink)

Scholars of classical philosophy have long disputed whether Aristotle was a dialectical thinker. Most agree that Aristotle contrasts dialectical reasoning with demonstrative reasoning, where the former reasons from generally accepted opinions and the latter reasons from the true and primary. Starting with a grasp on truth, demonstration never relinquishes it. Starting with opinion, how could dialectical reasoning ever reach truth, much less the truth about first principles? Is dialectic then an exercise that reiterates the prejudices of one's times and at (...) best allows one to persuade others by appealing to these prejudices, or is it the royal road to first principles and philosophical wisdom? In From Puzzles to Principles? May Sim gathers experts to argue both these positions and offer a variety of interpretive possibilities. The contributors' thoughtful reflections on the nature and limits of dialectic should play a crucial role in Aristotelian scholarship. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Circumcision:Ordinary and Universal in My CommunityAllan J. JacobsMy1 circumcision experiences are remarkable mostly for their ordinariness. My wife Danaë gave birth to our son Perseus2 while I was a resident in obstetrics and gynecology in a city where we had no family. Perseus was circumcised in a Jewish brit milah3 ceremony on the eighth day of his life, as were my wife's and my male ancestors back into ancient (...) times. We were relieved because Perseus had just recovered from a potentially serious condition. After a difficult forceps delivery, his blood bilirubin rose almost to the point where he might have developed the dreaded kernicterus syndrome. Kernicterus can cause permanent severe motor, intellectual and visual impairment. It was unclear whether he would be discharged from the hospital in time. He had to spend a week in restraints under a bright light whose frequency degraded bilirubin. Happily, he came home the day before the scheduled brit.Our four parents attended the brit. Danaë's father was the sandek,4 being granted the honor of holding our son on his lap during the circumcision ceremony. The mohel, or circumciser, was the local Conservative rabbi. We were mildly anxious because he didn't do many circumcisions in this city with few Jews. Perseus cried briefly after he was circumcised. The circumcision undoubtedly was far less stressful than treatment of elevated bilirubin. The circumcision certainly was less painful than the prodding and sticks for the many blood tests he had to undergo in the hospital, not to mention the pain of his difficult forceps delivery. Perseus did not seem to have much discomfort in his penis afterward, and had no circumcision complications.After the brit, our parents and my resident colleagues ate refreshments and chatted for an hour or so. A brit milah is a happy occasion, but not an elaborate one. It marks the end of the joy, anxiety, and excitement of the child's birth and its aftermath and is followed by the less exalted rhythm of feedings, diaper changes, and sleep deprivation.At the brit, our boys are assigned Hebrew names and confirmed in the Biblical covenant between God and the Hebrew people established between God and Abraham, and reaffirmed between God and Moses. Regardless of the historical truth of the formation of the covenant, it is accepted as a myth tantamount to [End Page 71] truth. In other words, regardless of its literal truth, such a myth is to be regarded as true because it concretizes God's demands or a moral truth. The covenant is real for me whether or not there was a historical Abraham. As with other religious commitments, the obligation to circumcise our sons is unprovable, but binding. On this basis, Perseus's ancestors on both sides were circumcised in brit milah ceremonies for many centuries into the past.My two grandsons were circumcised as well. Achilles was circumcised among friends and relatives. The mohel was an experienced obstetrician who was certified to officiate at a brit milah following the practices of Conservative Judaism. He administered adequate analgesia with topical local anesthetic cream followed by an injected regional block. Achilles slept through his circumcision, suffered no complications, and had little discomfort afterward. My other grandson had a circumcision performed as an infant outside the context of Judaism and is not being raised as a Jew.The two brit milah in my family were beautiful, dignified ceremonies, welcoming the infants into the Jewish fold, and bestowing their Hebrew names.5 Some of my relatives, including Perseus's son, had circumcisions performed in a medical setting without a ceremony. None of the many boys in my family had obvious short- or long-term problems with their circumcisions. My social circle has many Reform and Conservative Jews. I have never heard any Jewish man in my circle of acquaintances complain about his circumcision. Circumcision is a given. Problems are rare, and an exposed glans is the norm. Our men typically enjoy sex and have no difficulty in fathering children. Circumcision is part of the comforting cocoon of custom and tribe that helps to protect us as a group. It also reinforces Jewish endogamy... (shrink)
