In lieu of an abstract, here is a brief excerpt of the content:Keiji Nishitani and Karl Rahner: A Response to NihilityHeidi Ann RussellIn his essay “Kenosis and Emptiness,” Buddhist scholar Masao Abe states that “the necessity of tackling the Buddhist-Christian dialogue not merely in terms of interfaith dialogue, but also as an inseparable part of the wider sociocultural problem of religion versus irreligion has become more and more pressing in the past few decades.” 1 From Keiji Nishitani’s perspective a culture (...) of self-centeredness has developed out of the inability of many people to move beyond a sense of nihilism in their lives. Furthermore, technological advances and an increased understanding of the laws of nature have allowed humans to manipulate those laws for their own purposes. In this development, Nishitani believes that “the perversion that occurred in the original relationship of man to the laws of nature has taken the shape of a fundamental intertwining of the mechanization of man and his transformation into a subject in pursuit of its desires, at the ground of which nihility has opened up as a sense of the meaninglessness of the whole business.” 2Both Nishitani and Karl Rahner see in the development of science and technology a tendency to manipulate the laws of nature for one’s own benefit in a way that increases the self-centeredness and self-absorption of humankind while at the same time devaluing humanity and engendering an attitude of meaninglessness. In a world today that is confronted with issues such as war and global warming and in which religious communities are trying to make sense out of scientific issues such as stem cell research and cloning, the ability to address a nihilistic standpoint that sees the surrounding world as simply being at human disposal has never been more crucial. So how does one confront this crisis of a nihilistic culture? Abe recommends that both Buddhism and Christianity need “to pursue a fundamental reorganization in characterizing their faith such that the prevailing basic assumptions are drastically changed—for example, a revolutionary reinterpretation of the concept of God in Christianity and the concept of Emptiness in Buddhism—thereby allowing a new paradigm or model of understanding to emerge.” 3 The concept of emptiness or nothingness in Keiji Nishitani’s Religion and Nothingness and the concept of God as incomprehensible mystery in the theology of Karl Rahner 4 could allow for the [End Page 27] emergence of a model of understanding that addresses the problem of irreligion or nihility from an interreligious perspective.5 While in no way negating the very real dissimilarities between the concepts of Nishitani and Rahner or the respective religious traditions of which they are a part, one need not think of their concepts as diametrically opposed to one another in such a way that dialogue is impossible. To that effect, this essay will explore the common ground between Nishitani’s concept of śūnyatā6 (often translated or defined as ku /emptiness or mu /nothingness) and Rahner’s incomprehensible God 7 based on their interpretations of the human experience of meaninglessness and the need for a surrender of the self that manifests itself in one’s loving relationship with others. Common human experience, such as the experience of death or meaninglessness, and the interpretations of that experience found in various religions can provide ground from which to begin interreligious dialogue. One can search for a connection between the religious concepts by looking at the way they make sense out of a common affective experience without requiring an absolute identity between the cognitive religious concepts themselves.8 The important point of comparison is not manufacturing a false identity between the concepts, but the way the concepts work within the living communities to move one to volitive action. In this way the practical or ethical implications of the concepts and how they are lived out in the world become the focus. In the work of Nishitani and Rahner, that common human experience is the meaninglessness encountered in the world today and the call for a selfless love that will transcend such meaninglessness. In their roles as philosopher-theologians, both Nishitani and Rahner have probably had more influence on individuals or leaders within certain Buddhist and Christian... (shrink)

The dynamic developmental theory (DDT) has benefited from the insights of the commentators, particularly in terms of the implications for the proposed steepened delay gradients in attention-deficit/hyperactivity disorder (ADHD). The introduction of modified memory processes as a basis for the delay gradients improved the links to aspects of ADHD. However, it remains unclear whether the hyperactive-impulsive and inattentive subtypes are separate subgroups or may be explained as different outcomes of the same genetic factors and thus explicable by the same principles. (...) The DDT suggests that altered reinforcement and extinction processes define an endophenotype in ADHD that can be related dimensionally to inattention, hyperactivity, and impulsivity. The relation between the suggested endophenotype, characterized by changes in basic learning mechanisms, and other endophenotypes characterized by delay aversion or response disinhibition, needs to be tested in future studies.

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives rise to delay (...) aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to “inhibit” responses (“disinhibition”). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological “soft signs,” and a “failure to inhibit” responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns. Key Words: catecholamine; clumsiness; dopamine; hyperkinesis; hyperkinetic disorder; impulsivity; monoamine; neuromodulator; overactivity; pollutants; reinforcement; reward; verbally governed behavior; soft signs; variability.

The presented study introduces a new theoretical model of collapse for social, cultural, or political systems. Based on the current form of quantum anthropology conceptualized by Heidi Ann Russell, further development of this field is provided. The new theoretical model is called the spiral model of collapses, and is suggested to provide an analytical framework for collapses in social, cultural, and political systems. The main conclusions of this study are: 1) The individual crises in the period before a (...) collapse of social, cultural, and political systems form the trajectory of a conical helix similar to a vortex. 2) The occurrences of crises in the period before a collapse have the shape of the trajectory on the surface of the circular cone with a convex wall narrowing up to its peak. The shape of this cone is based on the Fibonacci sequence coiled into the three-dimensional space. 3) The constant circular movement along the trajectory of crises can occur in exceptional situations in the development of social, cultural, and political systems; however, such a state is always temporary. In such cases, the trajectory of the crisis does not follow the Fibonacci sequence, but the shape of a regular helix. Remaining on the trajectory of a regular helix in the long-term is highly improbable for social, cultural, and political systems. 4) The creation of new potentialities after the final collapse of a system is explained by the conception of topological inversion, when the heretofore embodied part of the energy-information field returns to the global, wave-particle energy-information potential. 5) The global, wave-particle energy-information potential is a source of energy-information for future embodiments in the sense of the future collapses of wave functions.

Going beyond the hype of recent fMRI "findings," this interdisciplinary collection examines such questions as: Do women and men have significantly different brains? Do women empathize, while men systematize? Is there a "feminine" ethics? What does brain research on intersex conditions tell us about sex and gender?

This article suggests that in the delicate balance between grace and freedom, the opposite of rejecting God’s grace is not acceptance of grace, but rather is non-rejection or the openness to God that is the human person’s obediential potency. Using the insights of Karl Rahner and David Coffey, this article goes on to explain efficacious grace and sufficient grace as the one self-communication of God in the modes of acceptance and rejection. To protect the human freedom, one must emphasize that (...) human persons can reject God’s offer of self, but to protect the gratuity of grace, one must acknowledge that acceptance of God’s grace is always undergirded and empowered by that same grace. The mediating point between these two modes is human openness or obediential potency for grace. One does not have to accept God’s grace to be this openness, but rather one must simply not reject God’s offer of grace, hence the primary categories of human freedom are not rejection and acceptance, but rejection and non-rejection.

The Covid-19 pandemic creates an unprecedented threatening situation worldwide with an urgent need for critical reflection and new knowledge production, but also a need for imminent action despite prevailing knowledge gaps and multilevel uncertainty. With regard to the role of research ethics in these pandemic times some argue in favor of exceptionalism, others, including the authors of this paper, emphasize the urgent need to remain committed to core ethical principles and fundamental human rights obligations all reflected in research regulations and (...) guidelines carefully crafted over time. In this paper we disentangle some of the arguments put forward in the ongoing debate about Covid-19 human challenge studies and the concomitant role of health-related research ethics in pandemic times. We suggest it might be helpful to think through a lens differentiating between risk, strict uncertainty and ignorance. We provide some examples of lessons learned by harm done in the name of research in the past and discuss the relevance of this legacy in the current situation. (shrink)

A recent article in this journal described practical and conceptual difficulties faced by public health researchers studying scabies outbreaks in British residential care facilities. Their study population was elderly, decisionally incapacitated residents, many of whom lacked a legally appropriate decision-maker for healthcare decisions. The researchers reported difficulties securing Research Ethics Committee approval. As practicing healthcare ethicists working in a large Canadian research hospital, we are familiar with this challenge and welcomed the authors’ invitation to join the discussion of the ‘outstanding (...) ambiguities and further questions’ that their experience uncovered. We propose a Power of Attorney for Research as one substantive solution to help address the problems they identified. Although we acknowledge the familiar shortcomings associated with Advance Directives in the clinical context, we believe that Powers of Attorney for Research Participation, accompanied by Advance Research Directives, may increase the likelihood of gaining deeper understandings of potential participant’s values and priorities and how they might apply to foreseeable research opportunities.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

Well-known predictors of prejudice toward Muslims include social dominance and authoritarianism. However, a gap exists for variables reflecting a rejection or mitigation of ideological motivations associated with prejudice toward Muslims. We examined if quiet ego was related to positive attitudes toward Muslims, and whether this could be explained by lower levels of authoritarianism, social dominance, and the motivation to express prejudice. We explored this possibility across two studies of adults in the United States. In Study 1, regression results showed quiet (...) ego was directly associated with positive attitudes toward Muslims. Study 2 utilized path analyses and found that the direct relationship between quiet ego and positive attitudes toward Muslims was explained by associations between quiet ego and lower endorsement of authoritarianism, social dominance, and the internal motivation to express prejudice toward Muslims. Moreover, these associations held when accounting for several correlates of intergroup attitudes. (shrink)

Magnetoencephalography is increasingly used for presurgical planning in people with medically refractory focal epilepsy. Localization of interictal epileptiform activity, a surrogate for the seizure onset zone whose removal may prevent seizures, is challenging and depends on the use of multiple complementary techniques. Accurate and reliable localization of epileptiform activity from spontaneous MEG data has been an elusive goal. One approach toward this goal is to use a novel Bayesian inference algorithm—the Champagne algorithm with noise learning—which has shown tremendous success in (...) source reconstruction, especially for focal brain sources. In this study, we localized sources of manually identified MEG spikes using the Champagne algorithm in a cohort of 16 patients with medically refractory epilepsy collected in two consecutive series. To evaluate the reliability of this approach, we compared the performance to equivalent current dipole modeling, a conventional source localization technique that is commonly used in clinical practice. Results suggest that Champagne may be a robust, automated, alternative to manual parametric dipole fitting methods for localization of interictal MEG spikes, in addition to its previously described clinical and research applications.

Picking up the question of what FLaK might be, this editorial considers the relationship between openness and closure in feminist legal studies. How do we draw on feminist struggles for openness in common resources, from security to knowledge, as we inhabit a compromised space in commercial publishing? We think about this first in relation to the content of this issue: on image-based abuse continuums, asylum struggles, trials of protestors, customary justice, and not-so-timely reparations. Our thoughts take us through the different (...) ways that openness and closure work in struggles against violence, cruel welcomes, and re-arrangements of code and custom. Secondly, we share some reflections on methodological openness and closure as the roundtable conversation on asylum, and the interview with Riles, remind us of #FLaK2016 and its method of scattering sources as we think about how best to mix knowledges. Thirdly, prompted by the FLaK kitchen table conversations on openness, publishing and ‘getting the word out’, we respond to Kember’s call to ‘open up open access’. We explain the different current arrangements for opening up FLS content and how green open access, the sharedit initiative, author request and publisher discretion present alternatives to gold open access. Finally drawing on Franklin and Spade, we show how there are a range of ‘wench tactics’—adapting gifts, stalling and resting—which we deploy as academic editors who are trying to have an impact on the access, use and circulation of our journal, even though we do not own the journal we edit. These wench tactics are alternatives to the more obvious or reported tactic of resignation, or withdrawing academic labour from editing and reviewing altogether. They help us think about brewing editorial time, what ambivalence over our 25th birthday might mean, and how to inhabit painful places. In this, we respond in our own impure, compromised way to da Silva’s call not to forget the native and slave as we do FLaK, and repurpose shrapnel, in our common commitments. (shrink)

This book provides practical and research-based chapters that offer greater clarity about the particular kinds of teacher reflection that matter and avoids talking about teacher reflection generically, which implies that all kinds of reflection are of equal value.

Abstract: Many, if not most philosophers, deny that a sentence like ‘Sherlock Holmes smokes’ could be true. However, this attitude conflicts with the assignment of true to that sentence by natural language speakers. Furthermore, this process of assigning truth values to sentences like ‘Sherlock Holes smokes’ seems indistinguishable from the process that leads speakers to assign true to other sentences, those like ‘Bertrand Russell smokes’. I will explore the idea that when speakers assign the value true to the first (...) sentence, they are not mistaken or confused — that we ought to take these assignments at face value. I show how the most popular alternative to this idea is inadequate for explaining various sentences involving fictional names. In addition, I offer evidence that these truth value assignments to sentences are tracking semantic content rather than pragmatic effects. (shrink)

This study is a major reappraisal of Virginia Woolf's relationship to Bloomsbury and the aesthetic and philosophical developments of her time. Through extensive archival research, Ann Banfield offers the first full analysis of Woolf's engagement with the theories of a remarkable trinity of thinkers: G. E. Moore, Bertrand Russell, and Roger Fry.

Several themes arise here. First is the need to coalition with ecofeminists in struggle against ecocide of our planet earth. Second is the incredible violence committed against Native women in the name of continuing manifest destiny. Third is the overlapping of racism, sexism, and capitalism to create an imperial system of domination over the earth's resources. Fourth, there is a need to heal ourselves and our communities. Authors include Bonita Lawrence, Ana Mariella Bacigalupo, M.A. Jaimes* Guerrero, Andrea Smith, Lisa M. (...)

In a recent article, Christopher Ormell argues against the traditional mathematical view that the real numbers form an uncountably infinite set. He rejects the conclusion of Cantor’s diagonal argument for the higher, non-denumerable infinity of the real numbers. He does so on the basis that the classical conception of a real number is mys- terious, ineffable, and epistemically suspect. Instead, he urges that mathematics should admit only ‘well-defined’ real numbers as proper objects of study. In practice, this means excluding as (...) inadmissible all those real numbers whose decimal expansions cannot be calculated in as much detail as one would like by some rule. We argue against Ormell that the classical realist account of the continuum has explanatory power in mathematics and should be accepted, much in the same way that "dark matter" is posited by physicists to explain observations in cosmology. In effect, the indefinable real numbers are like the "dark matter" of real analysis. (shrink)

Le logicisme de Russell consiste en une thèse affirmant que toutes les mathématiques pures peuvent être exprimées à l’aide de constantes logiques et de variables. Il est compris habituellement comme une réduction des mathématiques pures à la logique. Pourtant cette thèse est une garantie de non-réduction des mathématiques au nombre et à la grandeur, de l’arithmétique aux seuls nombres finis, de la géométrie à celle d’Euclide, de la logique à la syllogistique. Le logicisme ne peut donc être interprété comme (...) doctrine positive et dogmatique d’un fondement logique des mathématiques. L’œuvre philosophique de Russell poursuit par ailleurs une critique des thèmes liés aux fondements. L’ensemble des points de vues de Russell sur les liens de la lo­gique et des mathématiques ne peut être compris qu’en considérant la logique comme une science à part entière et non comme un langage formel. Cette façon d’aborder le logicisme fait voir des perspectives « hétérodoxes » auxquelles est amené Russell, qui n’est pas partout le « classique » que la littérature décrit trop vite. Cette lecture s’appuie notamment sur la correspondance récemment éditée entre Bertrand Russell et Louis Couturat (1897-1913). (shrink)

An initial distinction is made between two ways of referring in thought to a particular object. One can think of an object in virtue of having a descriptive condition in mind which uniquely denotes that object. Alternatively, one can think about a particular in a more direct way. It is with the nature of this more direct sort of reference that the subsequent discussion is primarily concerned. ;It has been argued that the relation of direct reference is purely causal in (...) nature. A number of difficulties are raised for this causal view. A diagnosis of these difficulties suggests that the causal view ignores the cognitive aspects of direct reference. ;The idea that direct reference is a cognitive relation is not new. Bertrand Russell's notion of knowledge by acquaintance can be thought of as involving the idea of a relation of reference which is direct and cognitive. A good place to begin an exploration of the cognitive dimensions of direct reference is with Russell's notion of acquaintance. Thus this notion is analysed in some depth. ;An objection to the effect that acquaintance is a relation incapable in principle of playing a role in an account of reference is shown to be unfounded. This clears the way for an extended discussion of the nature of acquaintance. This discussion suggests that we should posit a special demonstrative way in which objects can be presented to us. This demonstrative way of being presented with an object is in turn explored by way of an extended metaphor, in which it is suggested that becoming acquainted with an object should be thought of as the opening of a mental file of a special sort for that object. ;Some indirect support for this account of demonstrative modes of presentation and the associated account of direct reference comes from the fact that these notions can help solve the problem of cognitive significance that has been thought to pose a serious threat to theories that somehow treat reference as direct. ;Finally, some potential counterexamples are examined and shown not to seriously threaten the acquaintance theory of direct reference.

This is a reply to comments on my paper Cog, a Humanoid Robot, and the Questions of the Image of God; one was written by Mary Gerhart and Allan Melvin Russell, and another one by Helmut Reich. I will start with the suggested analogy of the relationship between God and us and the one between us and the humanoid robot Cog and will show why this analogy is not helpful for the dialogue between theology and artificial intelligence (AI). Such (...) a dialogue can succeed only if both our fascination for humanoids and our fear of them are equally accepted. Any avoidance of these emotions, as well as any rejection of the possibility that Cog might one day be humanlike, destroy the dialogue. The interpretation of both scientific theories and religious metaphors as stories replaces seemingly “rational” arguments with the confession of the respective commitments to a body of stories and opens up a space for exchange and friendship between AI‐researchers and theologians—an option that usually remains closed.

Yes, Aristotle was named ‘Aristotle’. I want to show that since ‘Aristotle’ is a proper name, this is true by definition. My theory of proper names is a version of Russell's, a theory that a name is equivalent in meaning to definite description which single out the individual, if there is one, to which the name refers. Braithwaite at one time said that the proper name ‘Aristotle’ meant the description ‘the individual named “Aristotle” ’. This theory, which makes it (...) contradictory to suppose that Aristotle was not named ‘Aristotle’ I will argue is the correct one. This will involve some explanation of what naming is, which I will carry out in the first two sections. My contention is that naming is an activity that can be done either explicitly or non-explicitly. And names can be conferred either on the basis of acquaintance or by associating the name with descriptions. (shrink)

Foerst says that a robot must have human features if it is to learn to relate to human beings. She argues that the image of God (imago dei) represents no more than a promise of God to relate to us. In our view, however, the principle of embodied artificial intelligence (AI) in the robot suggests some kind of embodiedness of the image of God in human beings if they are to learn to relate to God.Foerst's description of how people react (...) to a humanoid robot reads like Otto's description of the divine as mysterium fascinans et tremendum (awesome and alluring mystery). Her description makes robot‐human interaction seem more religious than human‐God interaction. (shrink)
