The cognitive science of religions’ By-Product Theory contends that much religious thought and behavior can be explained in terms of the cultural activation of maturationally natural cognitive systems. Those systems address fundamental problems of human survival, encompassing such capacities as hazard precautions, agency detection, language processing, and theory of mind. Across cultures they typically arise effortlessly and unconsciously during early childhood. They are not taught and appear independent of general intelligence. Theory of mind undergirds an instantaneous and automatic intuitive understanding (...) of minds, mental representations, and their implications for agents’ actions. By-Product theorists hypothesize about a social cognition content bias, holding that mentalizing capacities inform participants’ implicit understanding of religious representations of agents with counter-intuitive properties. That hypothesis, in combination with Baron-Cohen’s account of Autistic Spectrum Disorder in terms of diminished theory of mind capacities, suggests an impaired religious understanding hypothesis. It proposes that people with ASD have substantial limitations in intuitive understanding of and creative inferences from such representations. Norenzayan argues for a mind-blind atheism hypothesis, which asserts that the truth of these first two hypotheses suggests that people with ASD have an increased probability, compared to the general population, of being atheists. Numerous empirical studies have explored these three hypotheses’ merits. After carefully pondering distinctions between intuitive versus reflective mentalizing and between explicit versus implicit measures and affective versus cognitive measures of mentalizing, the available empirical evidence provides substantial support for the first two hypotheses and non-trivial support for the third.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Mettre en rapport des textes de Hegel sur l’amour érotique avec quelques passages du penseur romantique Friedrich Schlegel permet de mettre en relief la méfiance hégélienne à l’égard du désir sexuel. Selon l’échelle hiérarchique de désirs chez Hegel, le désir érotique fait preuve d’un déséquilibre entre le sujet désirant et l’objet désiré, ce qui est typique d’un rapport purement naturel et non spirituel. C’est dire que la connaissance charnelle, avec son objet dénué de Soi propre, représente pour Hegel une forme (...) inférieure de savoir. L’inégalité sujet-objet propre à l’amour érotique n’est dépassée que par la participation à la substance éthique, ce qui exige la reconnaissance réciproque de consciences de soi égales. Dans ce contexte, il s’agit du mariage. Juxtaposing some of Hegel’s texts on erotic love with certain passages from the romantic thinker Friedrich Schlegel throws light on Hegel’s problematic relationship with sexual desire. According to his hierarchy of types of desire, erotic desire betrays an imbalance between the desiring subject and the object of desire, typical of a purely natural, non-spiritual relation. This means that carnal knowledge, with its self-less object, represents an inferior form of knowing. The inequality between subject and object, inherent in erotic love, is only surpassed through participation in the ethical substance, requiring the reciprocal recognition of equal self-consciousnesses. In the present context, this means marriage. (shrink)

L'objectivité dont s'occupe la science hégélienne n'est pas celle d'une réalité détachée, mue selon les lois dialectiques, et le discours scientifique n'est pas vrai et objectif parce qu'il serait la réflexion adéquate d'une telle réalité. L'objectivité scientifique chez Hegel doit être saisie comme le logos , c'est-à-dire le discours de la science elle-même dans son actualité existante. Il s'agit d'un discours qui est son objet et qui est l'objectivité véritable. Ce type de langage est seulement possible s'il est compris comme (...) le moyen terme entre l'être et le penser, c'est-à-dire en termes du syllogisme hégélien et non pas de la prédication. Concrètement, les objets de la science, ou les contenus de l' Encyclopédie , sont eux-mêmes des discours objectifs, c'est-à-dire existants et vrais. Ainsi, par exemple, c'est seulement comme discours que l'Etat peut constituer un objet/contenu de la science hégélienne.The objectivity that Hegelian science deals with is not a detached reality running on dialectical laws, and scientific discourse is not true and objective because it is the faithful reflection of such a reality. Scientific objectivity, in Hegel, should be understood as logos, as existing scientific discourse. It is a discourse that is its object and is true objectivity. This type of language is only possible if it is grasped as the middle term between mere being and thought, in terms of the Hegelian syllogism rather than predication. Concretely, the objects of science, or the contents of the Encyclopedia, are themselves existing, true discourses. Thus, for example, only as discourse does the State become an object/content of science. (shrink)

ABSTRACTDiffraction gratings are famously associated with Henry Rowland of Johns Hopkins University but there were precursors. Although gratings were first made and used in Europe, reliable machines for ruling gratings were developed in the USA, and two men, Lewis Rutherfurd and William Rogers, tackled the problem before Rowland. Rutherfurd, a wealthy independent astronomer, designed and built the first screw-operated engine for ruling diffraction gratings, the fore-runner of almost all subsequent ruling engines. With it he and his assistant D. C. Chapman (...) ruled many gratings which he generously distributed to practising scientists, thereby materially advancing the science of spectroscopy. Rogers was a Harvard astronomer who developed an interest in the ruling of fine lines on glass that led him to construct a ruling engine with which he investigated the causes of the errors in the rulings he had examined. He continued to seek improvements with a second engine designed for ruling diffraction gratings. He ceased developing this engine when Rowland’s excellent gratings began to be available, concentrating instead on related problems to which he could apply the knowledge and skills he had gained, but his investigations assisted Rowland and other later ruling engine builders. This paper brings together what is known about the ruling engines of Rutherfurd and Rogers, their development, the gratings they produced, their quality and the work that was done with them, and assesses and compares their achievements and the impacts of the work of these two men.

SummaryDiffraction gratings have contributed enormously to modern science. Although some historians have written about them, there is much more to be brought to light. This paper discusses their development and use in the period up to about 1880 before Rowland began to produce them. Rittenhouse described the action of a diffraction grating in 1786, but no explanation was possible until the wave theory of light was developed. Fraunhofer discovered the dark lines in the solar spectrum in 1814, and then investigated (...) diffraction, producing the first ruled gratings, making detailed measurements and calculating the wavelengths of prominent spectral lines. After Bunsen and Kirchhoff showed the association between spectral lines and chemical elements there was an upsurge of interest in measuring wavelengths. The gratings used in this work almost all came from one source, a relatively unknown instrument maker called Nobert, who made them by an extremely laborious process using a machine he had built himself. The most significant wavelength measurements were made by Ångström, but Mascart, Van der Willigen, Stefan, Ditscheiner and Cornu also did important work. Nobert gratings were investigated by Quincke, copied photographically by Rayleigh, and were known and discussed in the USA. Nobert's work helped to advance spectroscopy much more than has been acknowledged. (shrink)

The present paper is an extract from a thesis concerning the debate between bradley and russell on the nature of relations. it concerns only the most general points of interaction - the positive influence of bradley upon russell with respect to psychologism, logic, and constructions; the negative influence: russell's work seen as a reaction to bradley. the intention is to show that bradley was an extremely strong influence in russell's development hardly worthy of the disregard which russell showed him.

A major problem in developing an effective gene therapy for the nervous system lies in understanding the principles that maintain or turn off the expression of genes following their transfer into the CNS.

We consider Berezin's algebraic considerations regarding the quantization of phase space polynomials. After making a connection with Prugovečki's stochastic quantization approach, we give a particular construction of Berezin's L-Kernel in terms of Prugovečki's ξ-functions.

In “Two Concepts of Liberty” Berlin notes the protean nature of the word “freedom” and then systematically proceeds to narrow its range of meanings. In the process, Berlin eliminates much of what most people, in everyday communication, regard as freedom, believing that this is in the best interest of intellectual clarity. As he puts it: [N]othing is gained by a confusion of terms. To avoid glaring inequality or widespread misery I am ready to sacrifice some, or all, of my freedom: (...) I may do so willingly and freely: but it is freedom that I am giving up for the sake of justice or equality or the love of my fellow men. I should be guilt‐stricken, and rightly so, if I were not, in some circumstances, ready to make this sacrifice. But a sacrifice is not an increase in what is being sacrificed, namely freedom, however great the moral need or the compensation for it. Everything is what it is: liberty is liberty, not equality or fairness or justice or culture, or human happiness or a quiet conscience. (Emphasis added). Berlin's other, perhaps overarching, aim is to show how inattention to the specificity of the meanings of concepts might have potentially dangerous political repercussions. He implicitly argues that the intellectuals who promoted the idea of positive freedom as opposed to that of negative freedom contributed to the emergence of totalitarianism and fascism in Europe.

Feed-forward Pavlovian conditioning can serve as a proximate mechanism for the evolution of social behavior. Feed-forward can provide the impetus for animals to associate other individuals' presence, and cooperation with them, with the acquisition of resources, whether or not the animals are genetically related. Other social behaviors such as play and grooming may develop as conditioned stimuli in feed-forward social systems.

Transsexualism, a condition in which from earliest recollection the individual is unshakeably convinced he or she has been endowed with the wrong physical sexual body presents one of the most difficult problems as regards management and treatment in clinical medicine. The aetiology and treatment is discussed and the problems with which the medical practitioner may be faced in advising his transsexual patient which include change in social role and marriage and the difference between sex and gender.
