A commonly used dynamic epistemic logic is one obtained by adding commonknowledge and public announcements to a basic epistemic logic. It is known from Kooi (2007) that adding public substitutions to such a logic adds expressivity over the class K of models. Here I show that substitutions also add expressivity over the classes KD45, S4 and S5 of models. Since the combination of common knowledge, public announcements and substitutions, was shown in Kooi (2007) to be equally expressive to relativized common (...) knowledge these results also show that relativized common knowledge is more expressive than common knowledge and public announcements over KD45, S4 and S5. These results therefore extend the result from van Benthem et al. (2006) that shows that relativized common knowledge is more expressive than common knowledge and public announcements over K.

We define balance games, which describe the formation of friendships and enmity in social networks. We show that if the agents give high priority to future profits over short term gains, all Pareto optimal strategies will eventually result in a balanced network. If, on the other hand, agents prioritize short term gains over the long term, every Nash equilibrium eventually results in a network that is stable but that might not be balanced.

Normative arrow update logic (NAUL) is a logic that combines normative temporal logic (NTL) and arrow update logic (AUL). In NAUL, norms are interpreted as arrow updates on labeled transition systems with a CTL-like logic. We show that the satisfiability problem of NAUL is decidable with a tableau method and it is in EXPSPACE.

“Neo-inclusivism” is explained and assessed as an approach to the problem of the conflicting claims to truth of different religions, with reference to inter alia John B. Cobb (Jr.), Gavin D'Costa and Paul Ingram. For the neo-inclusivist the truth of a religious tradition depends on its inclusivistic capacity, i.e. its capacity to assimilate other traditions. For ex ample, by being enriched and transformed through “radical openness” to other traditions, while remaining “committed” to her own tradition – so the neo-inclusivist claims (...) – the theology of the Christian can become “truly global”. Neo-inclusivism seemingly transcends the absolutist habits of inclusivists, i.e. to assess the religious other in view of criteria (the inclusivist's own religious tradition) with which the other does not identify himself or herself. However, the neo-inclusivist plays down the possible limits of inter religious openness and is overly optimistic about the possibility of a “truly global” theology. Moreover, whether the neo-inclusivist's “committed openness” significantly differs from the approach of those who arbitrarily use the definitive norms of their own religious tradition to assess other traditions, is at least debatable. Whatever the case may be, insofar as tolerance cannot tolerate intolerance, the neo-inclusivist is necessarily intolerant, and, in this sense, “absolutist”, towards those who make their own beliefs normative for all and shun themselves from the assessments and new insights of others.

The practice of ‘Philosophical Counselling’ (henceforth ‘PC’) is growing. But what exactly is PC? The variety of attempts to define PC can be summarised in terms of three overlapping sets of opposites: practical versus theoretical definitions; monistic versus pluralistic definitions; and substantive versus antinomous definitions. ‘Practical’ definitions of PC include descriptive accounts of its actual practice. ‘Theoretical’ definitions exclude such accounts. ‘Monistic definitions’ refers to definitions of PC that define it in terms of the work of one specific philosopher or (...) approach in philosophy. ‘Pluralistic’ definitions draw on the work of a variety of philosophers or approaches. ‘Substantive’ definitions are definitions that purport to say what PC is, while ‘antinomous’ definitions of PC say what it is not . My aim is not to define PC definitively. The aim of this article is rather to: (i) provide an overview of the wide variety of efforts to define PC; and, (ii) briefly suggest a preliminary understanding of PC that seems to cover most of the other definitions thereof.

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, as (...) proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

This article was motivated by the need to academically frame and share the response of the North-West University to the perceived increase of academic dishonesty during Covid-19. Within the ambit of the online teaching and learning approach that became dominant during the Covid-19 pandemic, the NWU established a Community of Practice for Academic Integrity to enhance Academic Integrity in a holistic manner. By critically discussing the NWU’s response through their CoPAI, the lessons learned, and strategies developed in the process, the (...) NWU can hopefully assist other Higher Education institutes to progressively enhance AI in the future. This is important, because many contextual shifts in teaching and learning approaches, pedagogy, assessment, and the application of technology, that were enforced in an online mode of delivery during the pandemic, will prevail in future.In writing this article, we focused on contextualising the NWU CoPAI within current literature on community of practice and Academic integrity and emphasising the unique strategy and holistic nature of this CoPAI. The establishment of the CoPAI is discussed within the appreciative inquiry as methodological framework. This methodology is commonly used by CoPs, but it is particularly relevant to the CoPAI since CoPAI sought answers to all the AI questions that presented itself due to disruptions in the higher education landscape. The appreciative inquiry method allowed for the opportunity to find some answers in a holistic manner. Some of these answers or insights gained through the activities of CoPAI is further discussed in the latter part of the article. In conclusion, some of the outcomes and shortcomings of CoPAI at the NWU are highlighted.The main finding of this article concluded that the establishment of a CoPAI can enhance AI at HE institutions in a holistic manner. The applicability, relevance, and success of this CoPAI was realised through its holistic approach which included the valorisation of institutional aspects, the engagement and empowerment of lecturers, and the engagement and empowerment of students. This novel and unique approach to promote AI in HE could fill the existing knowledge gap in the South African context, where the establishment of a CoPAI, the application of appreciative inquiry as methodology, and the inclusion of a holistic approach are still absent. It might however also be an example for other HE institutions to follow globally. (shrink)

The 1992 Convention on Biological Diversity (CBD) and its 2010 Nagoya Protocol brought about a breakthrough in global policy making. They combined a concern for the environment with a commitment to resolving longstanding human injustices regarding access to, and use of biological resources. In particular, the traditional knowledge of indigenous communities was no longer going to be exploited without fair benefit sharing. Yet, for 25 years after the adoption of the CBD, there were no major benefit sharing agreements that led (...) to significant funding streams for indigenous communities. This changed with the signing of the Rooibos Benefit Sharing Agreement in South Africa, described in this paper. As the authors report, the Rooibos Agreement is a superlative in two respects. It is the biggest benefit sharing agreement between industry and indigenous peoples to date. It is also the first industry-wide agreement to be formed in accordance with biodiversity legislation. This article is a co-production between traditional knowledge holders, the lawyer who represented their interests, the Co-Chair of the Nagoya Protocol negotiations, and an ethicist who analyzed the major challenges of this historic agreement. With no precedent in the benefit sharing world, the agreement stands as a concrete example of the ‘art of the possible.’ Although the rooibos case is unique in a number of aspects, the experience offers many transferable insights, including: patience; incrementalism; honesty; trust; genuine dialogue; strong legal support; a shared recognition that a fair, win-win deal is possible; government leadership; and unity amongst indigenous peoples. Such ingredients of success can apply well beyond southern Africa. (shrink)

In the past fifteen years, there has been a virtual explosion of anthropological literature arguing that morality should be considered central to human practice. Out of this explosion new and invigorating conversations have emerged between anthropologists and philosophers. Moral Engines: Exploring the Ethical Drives in Human Life includes essays from some of the foremost voices in the anthropology of morality, offering unique interdisciplinary conversations between anthropologists and philosophers about the moral engines of ethical life, addressing the question: What propels humans (...) to act in light of ethical ideals?

Since independence, at least 28 African countries have legalized some form of gambling. Yet a range of informal gambling activities have also flourished, often provoking widespread public concern about the negative social and economic impact of unregulated gambling on poor communities. This article addresses an illegal South African numbers game called fahfee. Drawing on interviews with players, operators, and regulatory officials, this article explores two aspects of this game. First, it explores the lives of both players and runners, as well (...) as the clandestine world of the Chinese operators who control the game. Second, the article examines the subjective motivations and aspirations of players, and asks why they continue to play, despite the fact that their aggregate losses easily outstrip their aggregate gains. In contrast with those who reduce its appeal simply to the pursuit of wealth, I conclude that, for the (mostly) black, elderly, working class women who play fahfee several times a week, the associated trade-off—regular, small losses, versus the social enjoyment of playing and the prospect of occasional but realistic windfalls—takes on a whole new meaning, and preferences for relatively lumpy rather than steady consumption streams help explain the continued attraction of fahfee. This reinforces the need to understand players’ own accounts of gambling utility rather than simply to moralistically condemn gambling or to dismiss gamblers behaviour as irrational. (shrink)

Dementia is an illness that raises important questions about our own attitudes to illness and aging. It also raises very important issues beyond the bounds of dementia to do with how we think of ourselves as people--fundamental questions about personal identity. Is the person with dementia the same person he or she was before? Is the individual with dementia a person at all? In a striking way, dementia seems to threaten the very existence of the self.LThis book brings together philosophers (...) and practitioners to explore the conceptual issues that arise in connection with this increasingly common illness. Drawing on a variety of philosophers such as Descartes, Lock, Hume, Wittgenstein, the authors explore the nature of personal identity in dementia. They also show how the lives and selfhood of people with dementia can be enhanced by attention to their psychological and spiritual environment. Throughout, the book conveys a strong ethical message, arguing in favor of treating people with dementia with all the dignity they deserve as human beings. The book covers a range of topics, stretching from talk of basic biology to talk of a spiritual understanding of people with dementia. Accessibly written by leading figures in psychiatry and philosophy, the book presents a unique and long overdue examination of an illness that features in so many of our lives. (shrink)

The article investigates the hypothesis that preaching implies more than merely verbalising, proclaiming and rhetoric reasoning. Preaching is fundamentally the art of poetic seeing; an aesthetic event on an ontic and spiritual level; that is, it provides vocabulary and images in order to help people to discover meaning in life (preaching as the art of foolishness). In this regard, preaching should provide God-images that open up the dimension of aesthetics and provide vistas of the ‘unseen’. The iconic dimension of preaching (...) is about symbols and metaphors that help people to ‘see’ in everyday life (a poetic gaze) the presence of God in such a way that tragic events, the awareness of death and the anguish about the fear for loss and rejection become events for signifying life and for healing (the quest for wholeness). It is argued that practical theology should be about a liturgy of life. In this regard, the ‘ugliness of God’ becomes an aesthetic category in a Christian spiritual approach to iconography. In order to do this a critical approach to praxis thinking should probe into the realm of paradigms, especially paradigms that describe the ‘power of God’. Due to the assumption that the depiction of God’s power was predominantly influenced by the Serapis, Zeus and Roman cult (Emperor mystique), a paradigm shift from omni-categories (pantokrator) to bowel categories (passio Dei) in the homiletic depiction of God is proposed.

The _Platform Sutra_ records the teachings of Hui-neng, the Sixth Patriarch, who is revered as one of the two great figures in the founding of Ch'an (Zen) Buddhism. This translation is the definitive English version of the eighth-century Ch'an classic. Phillip B. Yampolsky has based his translation on the Tun-huang manuscript, the earliest extant version of the work. A critical edition of the Chinese text is given at the end of the volume. Dr. Yampolsky also furnishes a lengthy and detailed (...) historical introduction which contains much information hitherto unavailable even to scholars, and provides the context essential to an understanding of Hui-neng's work. He gives an account of the history and legends of Ch'an Buddhism, with particular attention to the traditions associated with Hui-neng, quoting or summarizing the most important narratives. He then discusses the various texts of the _Platform Sutra_, and analyzes its contents. (shrink)

The late Jacob Klein’s important book is, remarkably, a lucid presentation of esoteric argument. Dealing with the famed Platonic triad, Theaetetus, Sophist, and Statesman, Klein settles the dispute about the missing dialogue, "The Philosopher," by first denying that it is missing and second showing that it is unnecessary. He argues, in short, that the triad is a dyad. That argument is reinforced by the distinction Klein strongly implies between the Socratic Theaetetus and the Eleatic Sophist and Statesman. "We can now (...) understand why the conversations of the ‘trilogy’ occur in two, not three, days and why the Sophist, the Statesman, and the Philosopher are dealt with in two, not three, dialogues".

Postcolonialism and decolonising campaigns are expressions of human pain on the level of identity confusion (inferiority), ideological abuse (cultural discrimination) and structural oppression (imperialistic exploitation). The slogan ‘Black Pain is a White Commodity’ in the #MustFall campaigns is critically analysed within the framework of postcolonial theory and imperialistic power categories. The basic hypothesis of the article is that in early Christianity, pantokrator images of God were influenced by iconography stemming mostly from the Roman Emperor cult and Egyptian mythology. The power (...) (omnipotence) and dominiumship of God directly and indirectly played a role in Christian imperialistic thinking regarding the expansion of the Kingdom of God and missio Dei strategies during times of European and colonial expansionism. In order to address the quest for ‘moving beyond’ in postcolonial theory, the impact of pantokrator-images of God on ecclesial thinking is researched. In order to contribute to sustainability and stability within the complexity of cultural diversity and current civil unrest on campuses in South Africa, the paracletic notion of compassionate being-with is developed within the framework of practical theological thinking. Instead of a Caesar-depiction, the theological notion of passio Dei is proposed: the decolonialising (post-imperialising) God. (shrink)

The pastoral ministry of caregiving inevitably implies a cost. The spiritual ethos in the Christian ministry implies a huge sacrifice. Dietrich Bonhoeffer described this ethos as ‘the cost of discipleship’. Very specifically in the case of unexpected and the so-called ‘undeserved modes of suffering’, the meaning framework of the caregiver is being interpenetrated, causing a kind of ‘depleted sense of being’. It is argued here that an appropriate diagnosis, and a description of the phenomenon of compassion fatigue, can help caregivers (...) to better understand their sense of being depleted. Instead of leaving the pastoral ministry, this can help them to attend anew to their spiritual capacity. In this regard, a theology of compassion, framed by theopaschitic theology, can help pastors to become ‘healed’ in order to re-enter the pastoral ministry and regain a sense of parrhēsia. (shrink)

In our exposure to weakness, vulnerability, loss, anguish and different forms of impairment, the following pastoral theological questions arises: What is meant by divine almightiness within the human need for spiritual strength, empowerment, encouragement and well-being? The epithet of almightiness (omnipotence, pantokratōr) gave birth to fictitious and speculative associations, even fear and anxiety: The paralyzing fear of God Almighty – divine intoxicating and spiritual pathology. Instead of a pantokratōr-definition of God, a paraklēsis-infinition of God is proposed. This paradigm shift is (...) based on the hermeneutical insight, namely, that the El Shadday of Yahweh is based on the respect in Jewish hermeneutics to render God not as a personified substance, but as an ‘operating verb’ – hjh. In the verbing of God, El Shadday points to encouragement, empowerment and a kind of pity and comfort based on the passio Dei. Contribution: How one perceives the power of God, determines the practice of Christian devotion and spirituality. Therefore, the emphasis on the notion of ‘God Almighty’ (omnipotence of God) and its link to the notion of the ‘weakness of God’ as exposed in the basic outline for a theology of the cross and as a source for hope in pastoral care and compassionate reaching out. (shrink)

Pastoral care must recover its unique identity as a theological discipline. In addressing the reality of evil, pastoral care reinterprets divine power as compassionate and creative empowerment, the basis for hopeful activity.
