In this unprecedented time, there are many questions and plenty of speculation surrounding what life will be like after the South African nationwide lockdown. There is concern over the effects that the lockdown will have on worship services when churches are in a position to open their doors to the public once more. As a result of recognising the lockdown as a liminal phase, perspectives are shared when considering how the church will gather again in a post-lockdown context and therefore (...) a post-liminal phase. One prevailing perspective in considering this post-liminal phase involves koinonia and how an undiscriminating virus can remind those to further practise inclusivity and ubuntu, by embracing sameness and difference when ‘being church’. In contrast, another important perspective focuses on ritualising certain measures in the worship service to prevent the spread of coronavirus disease 2019, when gathering in church buildings is permissible in a post-lockdown context. This is concluded by echoing the spirit of ubuntu, namely, ‘I am because we are’, in ‘being church’ during and after the crisis of the COVID-19 global pandemic.Contribution: From the perspective of Liturgical and Ritual Studies, this article aims to contribute to the Theological perspectives of COVID-19.

This collection of essays forms a lively debate over the fundamental characteristics of legal and moral rights. The essays examine whether rights fundamentally protect individuals' interests or whether they instead fundamentally enable individuals to make choices.

Illness is a reality that affects all people, and healing is the main reason why people attend worship services in sub-Saharan Africa. According to the Ritual Studies scholar Ronald Grimes, illness is a social reality; it is socially imagined and constructed. Healing in the church is something that many believers experience, also in the context of worship and liturgy. In order to explore such healing as it occurs in liturgy a research project was undertaken making use of both empirical work (...) and a literature study. The aim of this research was to take the light off of direct pastoral care and investigate how the liturgy affects individuals within the congregation with regard to healing. A praxis-theory cycle was followed in the research, and a preliminary liturgical theory for praxis was developed based on the insight from the empirical study and ritual theory that healing through worship entails either transformation or reconciliation.

It is human nature to wonder how things might have turned out differently--either for the better or for the worse. For the past two decades psychologists have been intrigued by this phenomenon, which they call counterfactual thinking. Specifically, researchers have sought to answer the "big" questions: Why do people have such a strong propensity to generate counterfactuals, and what functions does counterfactual thinking serve? What are the determinants of counterfactual thinking, and what are its adaptive and psychological consequences? This important (...) work brings together a collection of thought-provoking papers by social and cognitive psychologists who have made important theoretical and empirical contributions to our understanding of this topic. The essays in this volume contain novel theoretical insights, and, in many cases descriptions of previously unpublished empirical studies. The Psychology of Counterfactual Thinking provides an excellent overview of this fascinating topic for researchers, as well as advanced undergraduates and graduates in psychology--particularly those with an interest in social cognition, social judgment, decision judgment, decision making, thinking and reasoning.

O presente artigo tem como objeto o historicismo, a abordagem filosófica que considera a história como um fator crucial para a configuração dos valores e crenças e critérios dos homens e mulheres. De modo mais específico, eu exploro nas páginas seguintes alguns problemas que cercam a abordagem historicista e sua relação com a ação política e o discurso filosófico. Faço isso através da análise do pensamento de dois filósofos cuja contribuição tem sido considerada muito importante para a filosofia política hodierna: (...) Cornélius Castoriadis e Richard Rorty. Ambos os autores, além de decididamente historicistas, desenvolveram sua obra a partir de crítica e releitura de alguns elementos filosofia hegeliana e os dois procuram oferecer uma alternativa para a filosofia marxista. A minha análise de Castoriadis acompanha a sua crítica ao “universalismo objetivista do marxismo” e a sua proposta de uma “ontologia histórica” para daí então comentar alguns possíveis problemas decorrentes do seu historicismo. Em seguida eu exploro as possíveis virtudes da filosofia de Castoriadis, apontadas por Richard Rorty, para em seguida mostrar como o próprio Rorty oferece uma possível saída aos impasses do historicismo de Castoriadis.

The suppression of the Modus Ponens inference is described as a loss of confidence in the conclusion C of an argument “If A1 then C; If A2 then C; A1” where A2 is a requirement for C to happen. It is hypothesised that this loss of confidence is due to the derivation of the conversational implicature “there is a chance that A2 might not be satisfied”, and that different syntactic introductions of the requirement A2 (e.g., “If C then A2”) will (...) lead to various frequencies in the derivation of this implicature, according to previous studies in the field of causal explanation. An experiment is conducted, whose results support those claims. Results are discussed in the light of the Mental Logic and Mental Model theories, as well as in the light of the pragmatic approach to uncertain reasoning. (shrink)

Previous articles on Russell's hypothesis and on criteria for scientific explanations are used as a springboard for analyzing some modern trends in science. Specifically, recent suggestions of the concept of "creation from nothing" in Big-Bang cosmology are compared to Russell's hypothesis, in light of James Woodward's criteria for an explanation purporting to be scientific. The discussion is then extended to the broader question of the direction of scientific theorizing, through examples showing that one generation's science may not build conformably upon (...) the mindset of the previous generation.

§1. Introduction. Asymptotic cones of metric spaces were first invented by Gromov. They are metric spaces which capture the ‘large-scale structure’ of the underlying metric space. Later, van den Dries and Wilkie gave a more general construction of asymptotic cones using ultrapowers. Certain facts about asymptotic cones, like the completeness of the metric space, now follow rather easily from saturation properties of ultrapowers, and in this survey, we want to present two applications of the van den Dries-Wilkie approach. Using ultrapowers (...) we obtain an explicit description of the asymptotic cone of a semisimple Lie group. From this description, using semi-algebraic groups and non-standard methods, we can give a short proof of the Margulis Conjecture. In a second application, we use set theory to answer a question of Gromov.§2. Definitions. The intuitive idea behind Gromov's concept of an asymptotic cone was to look at a given metric space from an ‘infinite distance’, so that large-scale patterns should become visible. In his original definition this was done by gradually scaling down the metric by factors 1/nfornϵ ℕ. In the approach by van den Dries and Wilkie, this idea was captured by ultrapowers. Their construction is more general in the sense that the asymptotic cone exists for any metric space, whereas in Gromov's original definition, the asymptotic cone existed only for a rather restricted class of spaces.

This book brings together contributions from seventeen of the world's foremost legal and political philosophers to examine the lasting influence of H.L.A. Hart. The essays explore the major subjects of Hart's work: general jurisprudence, criminal responsibility, rights, justice, causation and the foundations of liberalism.

Recently, psychological phenomena have been expanded to new domains, crisscrossing boundaries of organizational levels, with the emergence of areas such as social personality and ecosystem learning. In this contribution, we analyze the ascription of an individual-based concept (personality) to the social level. Although justified boundary crossings can boost new approaches and applications, the indiscriminate misuse of concepts refrains the growth of scientific areas. The concept of social personality is based mainly on the detection of repeated group differences across a population, (...) in a direct transposition of personality concepts from the individual to the social level. We show that this direct transposition is problematic for avowing the nonsensical ascription of personality even to simple electronic devices. To go beyond a metaphoric use of social personality, we apply the organizational approach to a review of social insect communication networks. Our conceptual analysis shows that socially self-organized systems, such as isolated ant trails and bee’s recruitment groups, are too simple to have social personality. The situation is more nuanced when measuring the collective choice between nest sites or foraging patches: some species show positive and negative feedbacks between two or more self-organized social structures so that these co-dependent structures are inter-related by second-order, social information systems, complying with a formal requirement for having social personality: the social closure of constraints. Other requirements include the decoupling between individual and social dynamics, and the self-regulation of collective decision processes. Social personality results to be sometimes a metaphorical transposition of a psychological concept to a social phenomenon. The application of this organizational approach to cases of learning ecosystems, or evolutionary learning, could help to ground theoretically the ascription of psychological properties to levels of analysis beyond the individual, up to meta-populations or ecological communities.

"The Bush administration and Congress are in concert on the goal of developing a fleet of unmanned aircraft that can reduce both defense costs and aircrew losses in combat by taking on at least the most dangerous combat missions. Unmanned combat aerial vehicles (UCAVs) will be neither inexpensive enough to be readily expendable nor-- at least in early development-- capable of performing every combat mission alongside or in lieu of manned sorties. Yet the tremendous potential of such systems is widely (...) recognized, and allies as well as potential adversaries are moving quickly to mount their own research and development programs. The United States is committed to fielding UCAV capabilities by 2010, principally for the missions of suppression of enemy air defense and deep strike, which are among the highest risk tasks for the Air Force and naval aviation."--Overview.

'Philosophy' in the context of this book means that the author is looking at education as a whole, without restrictions or simplifications; looking at ends and purposes, not merely at methods and means.

The purpose of this study was to compare working memory (WM), executive function, academic ability and problem classroom behaviors in children aged 8 to 11 years who were either identified via routine screening as having low WM, or had been diagnosed with ADHD. Standardised assessments of WM, executive function and reading and mathematics were administered to 83 children with ADHD, 50 children with low WM and 50 typically developing children. Teachers rated problem behaviors on checklists measuring attention, hyperactivity/impulsivity, oppositional behavior, (...) and difficulties associated with executive function in the classroom. The ADHD and low WM groups had highly similar WM and executive function profiles, but were distinguished in two key respects: children with ADHD had higher levels of rated and observed impulsive behavior, and children low WM had slower response times. Possible mechanisms for these common and distinct deficits are discussed. (shrink)
