Poverty remains a critical socio-economic challenge in South Africa, deeply rooted in the country’s history of colonialism and apartheid. This article examines the multifaceted role of churches in poverty alleviation efforts in South Africa, spanning both historical and contemporary contexts. Through analysis of historical records and contemporary literature, it argues that while churches have significantly addressed poverty, a more comprehensive and transformative approach is needed. The study proposes adopting a missional ecclesiology framework to enhance the effectiveness of church-led poverty alleviation (...) initiatives, offering insights into how churches can engage more deeply and sustainably in the fight against poverty.Contribution: This research contributes to existing scholarship by: (1) Providing a comprehensive historical analysis of church involvement in poverty alleviation in South Africa. (2) Critically examining challenges and opportunities in contemporary church-led poverty alleviation efforts. (3) Proposing missional ecclesiology as a framework for enhancing church-based poverty alleviation initiatives. (4) Offering practical recommendations for churches to address poverty within South Africa’s unique socio-economic context. (shrink)

We describe our explicit Lorentz-invariant solution of the Einstein and null geodesic equations for the deflection experiment of 2002 September 8 when a massive moving body, Jupiter, passed within 3.7’ of a line-of-sight to a distant quasar. We develop a general relativistic framework which shows that our measurement of the retarded position of a moving light-ray deflecting body (Jupiter) by making use of the gravitational time delay of quasar’s radio wave is equivalent to comparison of the relativistic laws of the (...) Lorentz transformation for gravity and light. Because, according to Einstein, the Lorentz transformation of gravity field variables must depend on a fundamental speed c, its measurement through the retarded position of Jupiter in the gravitational time delay allows us to study the causal nature of gravity and to set an upper limit on the speed of propagation of gravity in the near zone of the solar system as contrasted to the speed of the radio waves. In particular, the v/c term beyond of the standard Einstein’s deflection, which we measured to 20% accuracy, is associated with the aberration of the null direction of the gravity force (“aberration of gravity”) caused by the Lorentz transformation of the Christoffel symbols from the static frame of Jupiter to the moving frame of observer. General relativistic formulation of the experiment identifies the aberration of gravity with the retardation of gravity because the speed of gravitational waves in Einstein’s theory is equal to the speed of propagation of the gravity force. We discuss the misconceptions which have inhibited the acceptance of this interpretation of the experiment. We also comment on other interpretations of this experiment by Asada, Will, Samuel, Pascual–Sánchez, and Carlip and show that their “speed of light” interpretations confuse the Lorentz transformation for gravity with that for light, and the fundamental speed of gravity with the physical speed of light from the quasar. For this reason, the “speed of light” interpretations are not entirely consistent with a retarded Liénard–Wiechert solution of the Einstein equations, and do not properly incorporate how the phase of the radio waves from the quasar is perturbed by the retarded gravitational field of Jupiter. Although all of the formulations predict the same deflection to the order of v/c, our formulation shows that the underlying cause of this deflection term is associated with the aberration of gravity and not of light, and that the interpretations predict different deflections at higher orders of v/c beyond the Shapiro delay, thus, making their measurement highly desirable for deeper testing of general relativity in future astrometric experiments like Gaia, SIM, and SKA.

In this book, Yaqub describes a simple conception of truth and shows that it yields a semantical theory that accommodates the whole range of our seemingly conflicting intuitions about truth. This conception takes the Tarskian biconditionals as correctly and completely defining the notion of truth. The semantical theory, which is called the revision theory, that emerges from this conception paints a metaphysical picture of truth as a property whose applicability is given by a revision process rather than by a fixed (...) extension. The main advantage of this revision process is its ability to explain why truth seems in many cases almost redundant, in others substantial, and yet in others paradoxical. Yaub offers a comprehensive defense of the revision theory of truth by developing consistent and adequate formal semantics for languages in which all sorts of problematic sentences can be constructed. Yaqub concludes by introducing a logic of truth that further demonstrates the adequacy of the revision theory. (shrink)

This book takes a bold new look at ways of exploring the nature, origins, and potentials of consciousness within the context of science and religion.

Neuronal aggregates involved in conscious awareness are not evenly distributed throughout the CNS but comprise key components referred to as the neural network correlates of consciousness (NNCC). A critical node in this network is the posterior cingulate, precuneal, and retrosplenial cortices. The cytological and neurochemical composition of this region is reviewed in relation to the Brodmann map. This region has the highest level of cortical glucose metabolism and cytochrome c oxidase activity. Monkey studies suggest that the anterior thalamic projection likely (...) drives retrosplenial and posterior cingulate cortex metabolism and that the midbrain projection to the anteroventral thalamic nucleus is a key coupling site between the brainstem system for arousal and cortical systems for cognitive processing and awareness. The pivotal role of the posterior cingulate, precuneal, and retrosplenial cortices in consciousness is demonstrated with posterior cingulate epilepsy cases, midcingulate lesions that de-afferent this region and are associated with unilateral sensory neglect, observations from stroke and vegetative state patients, alterations in blood flow during sleep, and the actions of general anesthetics. Since this region is critically involved in self reflection, it is not surprising that it is similarly a site for the NNCC. Interestingly, information processing during complex cognitive tasks and during aversive sensations such as pain induces efforts to terminate self reflection and result in decreased processing in posterior cingulate and precuneal cortices.

On Islamic standards of basic needs of human beings.

This essay explains the inescapability of moral demands. I deny that the individual has genuine reason to comply with these demands only if she has desires that would be served by doing so. Rather, the learning of moral reasons helps to shape and channel self- and other-interested motivations so as to facilitate and promote social cooperation. This shaping happens through the “embedding” of reasons in the intentional objects of motivational propensities. The dominance of the instrumental conception of reason, according to (...) which reasons must be based in desires of the individual, has made it harder to recognize that reasons shape desires. I attempt to undermine this dominance by arguing that the concept of a self that extends over time is constructed to meet the demands of social cooperation. Prudential reasons to act on behalf of the persisting self's desires are often taken to constitute the paradigm of reasons based on desires of the individual. But such reasons, along with the very concept of the persisting self, are constructed to promote human cooperation and to shape the individual's desires. (shrink)

In this collection, Stations on the Journey of Inquiry, David Burrell launches a revolutionary reinterpretation of how any inquiry proceeds, boldly critiquing presumptuous theories of knowledge, language, and ethics. While his later publications, Analogy and Philosophical Language (1973) and Aquinas: God and Action (1979), elucidate Aquinas's linguistic theology, these early writings show what often escapes articulation: how one comes to understanding and "takes" a judgment. Although Aquinas serves as an axial figure for Burrell's expansive corpus of scholarship spanning more than (...) fifty years, this selection of essays presents other positions and counterpositions to whom his own philosophical theology is beholden: Plato, Aristotle, Cajetan, Kant, Peirce, Moore, Wittgenstein, Sellars, Weiss, Ross, McInerny, and Lonergan. With renewed interest in philosophy of language by postmodern thinkers as well as in the wake of Mulhall's Stanton Lectures on Wittgenstein and "Grammatical Thomism," the publication of these formative writings proves timely for the academy at large. Burrell invites us to reconsider not only the way in which we conduct an inquiry, but what it is we take language to be and how we take responsibility for what we say. (shrink)

Chaos theory is a rapidly growing field. As a technical term, chaos refers to deterministic but unpredictable processes being sensitively dependent upon initial conditions. Neurobiological models and experimental results are very complicated and some research groups have tried to pursue the neuronal chaos. Babloyantz's group has studied the fractal dimension (d) of electroencephalograms (EEG) in various physiological and pathological states. From deep sleep (d=4) to full awakening (d>8), a hierarchy of strange attractors paralles the hierarchy of states of consciousness. In (...) epilepsy (petit mal), despite the turbulent aspect of a seizure, the attractor dimension was near to 2. In Creutzfeld-Jacob disease, the regular EEG activity corresponded to an attractor dimension less than the one measured in deep sleep. Is it healthy to be chaotic? An active desynchronisation could be favourable to a physiological system. Rapp's group reported variations of fractal dimension according to particular tasks. During a mental arithmetic task, this dimension increased. In another task, a P300 fractal index decreased when a target was identified. It is clear that the EEG is not representing noise. Its underlying dynamics depends on only a few degrees of freedom despite yet it is difficult to compute accurately the relevant parameters.What is the cognitive role of such a chaotic dynamics? Freeman has studied the olfactory bulb in rabbits and rats for 15 years. Multi-electrode recordings of a few mm2 showed a chaotic hierarchy from deep anaesthesia to alert state. When an animal identified a previously learned odour, the fractal dimension of the dynamics dropped off (near limit cycles). The chaotic activity corresponding to an alert-and-waiting state seems to be a field of all possibilities and a focused activity corresponds to a reduction of the attractor in state space. For a couple of years, Freeman has developed a model of the olfactory bulb-cortex system. The behaviour of the simple model without learning was quite similar to the real behaviour and a model with learning is developed. (shrink)

This essay reflects on 25 years since Christian Bioethics began publication and, in somewhat autobiographical fashion, engages two core concerns. First, although “non-ecumenism” may often appear a pretext for contention and division, I suggest that a respectful non-ecumenism may provide the opportunity for dialogue and the occasion for employing certain tools from religious studies. Second, although many are skeptical about the possibilities of identifying a “common morality,” a defense of that notion provides a plausible explanation for the development of limited (...) consensus on some issues in bioethics.

Modern science developed in the interflow of culture between west and east. Combing of pratice technology with philosophic thoughts formed experimental method. Holistic views contacting atomism produced system theory. System thoughts are applicated in the science and engineering of biosystems, and the cencepts of system biomedicine (Kamada T.1992), systems biology (Zieglgansberger W, Tolle TR.1993), system bioengineering and system genetics (Zeng BJ. 1994) were established. From positive to synthetic thoughts, philosophy have been developed ontology, cosmology, organism theories. Structurity is structure logic (...) system founded on entity, develop, exist axioms, tolerance, adaptation, fluctuate, interweave, transform theorems and integrate, adaptation, construct laws. Structurity be discussed on the cosmos, life, culture system, creation, hologram theories of structure ontology, construct mutation, simi-structure organism and entity emergence, symbol implication. From the relation of structure, function and development, the structurity put forward the cycle, spiral, triangle structure stability patterns of self-organization in structure complement each other and stratification, functional couple and interflow bounds growth, coordinativetransformation and holographic symmetry.
