AimVisual functions of the dorsal stream are considered vulnerable in children with early brain damage. Considering the recognition of objects in suboptimal representations a dorsal stream dysfunction, we examined whether children with early brain damage and impaired object recognition had either general or selective dorsal stream dysfunctions.MethodIn a group of children with early brain damage we evaluated the dorsal stream functioning. To determine whether these patients had an increased risk of a dorsal stream dysfunction we compared the percentage of patients (...) with impaired object recognition, assessed with the L94, with the estimated base rate. Then we evaluated the performance levels on motion perception, visual attention and visuomotor tasks in patients with and without object recognition abnormalities. A general dorsal stream dysfunction was considered present if a patient showed at least one abnormally low score in two out of three additional dorsal stream functions.ResultsSix of the eighteen patients with object recognition problems scored abnormally low on at least two additional dorsal stream functions. This was significantly higher than the base rate. The difference of 24.1% between the patients with and without object recognition problems was not significant. Of the patients with object recognition problems 72.2% had at least 1 dorsal weakness, whereas this was only the case in 27.3% of patients without object recognition problems. Compared to patients with normal object recognition, patients with object recognition problems scored significantly more abnormally low on motion perception and visual attention but did not differ on visuomotor skills.ConclusionChildren with object recognition problems seem at risk for other dorsal stream dysfunctions, but dysfunctions might be rather specific than general. Multiple functions/aspects should be evaluated in neuropsychological assessment of children at risk. (shrink)

CQ: The Baby Bas Ross case stirred much public debate in The Netherlands since 1988 -a newborn infant with Down's syndrome whose parents refused to consent to a surgery that would have repaired an otherwise fatal congenital anomaly. Can you share your thoughts with us on this case?HD: I was the first ethicist to comment on this case because I was a friend of Dr. Molenaar, who was the final surgical decision maker for Baby Bas. A physician and I supported (...) his decision throughout the prosecution that followed. We also summarized the case in the N.T.V.G., the Dutch Magazine of Medicine. We argued In the article that parents should have the option to make nontreatment decisions. Moreover, In cases where the physician has to perform aggressive medical interventions, there certainly must be thorough and sound justification to ensure that the decision to Intervene Is in the best interest of the child.Heleen M. Dupuis, Ph.D., is Professor of Bioethics at the Leiden University School of Medicine, where she heads the Department of Metamedica and teaches in the Department of Philosophy.

The Christian church had its early development in the Hellenistic, Greco-Roman world and for that reason it can certainly be stated that the church was “Hellenized”. But how should we define this Hellenization? And what should be our judgement of it? The collection of essays entitled Hellenization revisited centers on an important theme.

Ethicists differ considerably in their reasons for using empirical data. This paper presents a brief overview of four traditional approaches to the use of empirical data: “the prescriptive applied ethicists,” “the theorists,” “the critical applied ethicists,” and “the particularists.” The main aim of this paper is to introduce a fifth approach of more recent date (i.e. “integrated empirical ethics”) and to offer some methodological directives for research in integrated empirical ethics. All five approaches are presented in a table for heuristic (...) purposes. The table consists of eight columns: “view on distinction descriptive-prescriptive sciences,” “location of moral authority,” “central goal(s),” “types of normativity,” “use of empirical data,” “method,” “interaction empirical data and moral theory,” and “cooperation with descriptive sciences.” Ethicists can use the table in order to identify their own approach. Reflection on these issues prior to starting research in empirical ethics should lead to harmonization of the different scientific disciplines and effective planning of the final research design. Integrated empirical ethics (IEE) refers to studies in which ethicists and descriptive scientists cooperate together continuously and intensively. Both disciplines try to integrate moral theory and empirical data in order to reach a normative conclusion with respect to a specific social practice. IEE is not wholly prescriptive or wholly descriptive since IEE assumes an interdepence between facts and values and between the empirical and the normative. The paper ends with three suggestions for consideration on some of the future challenges of integrated empirical ethics. (shrink)

The Dutch law states that a physician may perform euthanasia according to a written advance euthanasia directive when a patient is incompetent as long as all legal criteria of due care are met. This may also hold for patients with advanced dementia. We investigated the differing opinions of physicians and members of the general public on the acceptability of euthanasia in patients with advanced dementia.

Since the late 1990s, the Russian Orthodox Church and several mainline Western Protestant churches have been at odds over homosexuality to such an extent that it has turned into a church-dividing issue. This article aims to find new openings for the ecumenical dialogue by examining how the ROC’s negative attitude toward same-sex relations has been influenced by cultural and historic factors. The analysis focuses on the affective dimension of the ROC’s discourse on homosexuality in important social documents and public speeches. (...) The methodology applied is taken from affect studies. The rhetoric of the ecclesial texts recalls ‘shadows from the gulag’ and frightening memories of the chaos of the 1990s, and functions to create an imagined national, moral and religious community – the ‘Russian Christian civilization’ – which is characterized by masculine heterosexuality. Religious concepts tend to become subordinate to the affective politics of the discourse. In conclusion, the author proposes that ecumenical partners continue with a profound theological discussion on human sexuality in all its diversity and complexity, and clarify to each other how understandings of basic theological notions such as human dignity and freedom have also been shaped by formative historic experiences. Furthermore, ecclesiological debates should address, at a fundamental level, the relationship between Christian community and the freedom ‘to be different.’. (shrink)

Deep neural network (DNN) models of human-like vision are typically built by feeding blank slate DNN visual images as training data. However, the literature on human perception and perceptual learning suggests that developing DNNs that truly model human vision requires a shift in approach in which perception is not treated as a largely bottom-up process, but as an active, top-down-guided process.

Emotions are ”feelings of bodily changes’, according to William James. This definition was the starting point of a debate that has been going on for more than a century now. James’ approach soon seemed empirically falsified by experimental psychologists and it was seriously undermined by philosophers who called his views untenable, because he seemed to reduce emotions to non-cognitive sensations. But time and again James rose from his grave. Today we witness his revival in the work of ”neo-Jamesians’ like Jesse (...) Prinz and ”neo-phenomenologists’ like Matthew Ratcliffe. In this article the main reactions to James’ ”feelings of bodily changes’ are examined. My conclusion is that both his critics and his supporters have started from an incomplete interpretation of the theory. James’ pragmatically embedded psychology of emotion as the experience of a dynamic, bodily self has until today received insufficient philosophical attention. (shrink)

Overzicht van de gewijzigde visie in de 20e-eeuwse filosofie op emoties.

William James’s reputation in the field of emotion research is based on his early psychological writings where he defines emotions as ‘feelings of bodily changes’. In his later work, particularly in his study of mystic emotion, James comes up with what looks like a completely different approach. Here his focus is on positive feelings of inspiration and joy, but also on downbeat moods like melancholy and depression. He examines how these feeling states give meaning to an individual’s life. Theorists often (...) speculate about a gap between James’s early writings and his later work, and assume that the later James turned from an evolutionary-minded natural scientist into a metaphysical philosopher. In my paper, I follow Ratcliffe in his view that a sharply drawn line between the early and the late work is implausible and that James’s later study of mysticism fits nicely with his early psychology. Drawing on James, I show how in his later work, James develops a theory of embodied emotions that anticipates the role ascribed by twentieth century phenomenology to anxiety and other ‘bad moods’, as possibilities for philosophical reflection and self-understanding.

For the theorists of crisis, the revolutionary state comes into existence through violence, and due to its inability to provide an authoritative katechon (restrainer) against internal and external violence, it perpetuates violence until it self-destructs. Writing during extreme economic depression and growing social and political violence, the crisis theorists––Joseph de Maistre, Juan Donoso Cortés, and Carl Schmitt––each sought to blame the chaos of their time upon the Janus-faced postrevolutionary ideals of liberalism and socialism by urging a return to pre-revolutionary moral (...) and religious values. They are united by three counterrevolutionary principles, all of which are purported to remedy revolutionary violence: traditional constitutional fidelity, the philosophy of the decision, and opposition to bourgeois liberalism. This essay is followed by the first complete English translation and publication of Donoso’s letter of October 24, 1851, which contains Donoso’s only reference to the “discussing class,” a political entity later popularized by Schmitt in his 1922 work Political Theology.

The idea of the spherical world, poised in space, and encircled at different distances by the celestial bodies, was introduced by the early Greek cosmologists. With some modifications, it is still our Western world-picture. It differs fundamentally from that of other cultures, which all accept, in one version or another, the idea of a flat earth with the dome of the celestial vault above it. The Greek conception, however, entails the problem of falling. How to account for the earth's stability? (...) Why is it that the earth does not fall? This anxious question has already bothered the Presocratics. Aristotle provided the solution that was satisfying for many hundred of years. Falling, according to Aristotle, is not the problem, but the answer, as the earth, consisting of the heaviest of the elements, finds its natural place in the centre of the spherical universe. For the same reason the earth itself, according to Aristotle, has to be spherical. Thus, his main line of argumentation was what we now would call 'metaphysical'. Recently, some scholars have argued that the early Greek idea of a spherical earth was developed as a protoscientifie hypothesis, based on empirical reasoning and observation. In this article, we show this to be an example of the 'anachronistic fallacy' that seriously obscures our understanding of the ancient Greek philosophers. Aristotle's conception held for two millennia, until the work of Copernicus, Kepler, and Thomas Digges overthrew it. Consequently, Newton had to cope with the fear of falling again — a fear that still haunts our modern world-picture and that was brilliantly articulated by Blaise Pascal, in his Pensées. (shrink)

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Introduction to collection of papers by group of scholars and ACO missionaries brought together to discuss the developments within the ACO over the past hundred years during a conference that was organised by Dr Wilbert van Saane of Haigazian University in January 2021. I will briefly summarise what strikes me as characteristic of the ACO on the basis of these articles, and conclude with a discussion of how this may contribute to further reflection in Mission Studies and World Christianity.
