A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein's famous E = mc² . The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

In lieu of an abstract, here is a brief excerpt of the content:Apostolic Letter of Our Most Holy Father PAUL VI, by Divine Providence, POPE to Our Venerable Brethren, Cardinal John Carmel Heenan, Archbishop of Westminster, and Gordon Joseph Gray, Archbishop of Saint Andrews and Edinburgh and to the other Archbishops and Bishops of England, Wales and Scotland. On the Occasion of the Second Scholastic Congress held at Oxford and Edinburgh on the Seventh Centenary of the Birth of John Duns (...) Scotus. Venerable Brethren, Greetings and Apostolic Blessing: A devoted mother of valiant men, Great Britain is distinguished by a quality no less estimable than the honour and the feats of her glorious children, for she knows how to cherish fondly the memory of her glorious sons and, when tradition demands that recurrences be celebrated solemnly, she knows how to sing their praises as though striving to repay them a debt of honour. These were the thoughts that sprang to our mind, and gave no slight satisfaction as we dwelt upon them, when we first learned the details of the Second International Scholastic Congress which is being prepared in your countries in memory of the Venerable John Duns Scotus on the seven hundredth anniversary of his birth. This Congress will be held at Oxford and Edinburgh under your patronage, Venerable Brethren, with lively interest and careful organization. One can already foresee that it will produce excellent results and will be of considerable importance, in view both of the arguments that will be discussed and of the distinguished persons who will take part in the sessions. Universities of England and Scotland and, from abroad, the universities of Paris and Cologne where he lectured, and many others, will send official representatives; apart from Catholics, there will be outstanding members of the Anglican Communion, of the Church of Scotland, of other Christian Communities of Great Britain, and well known exponents of sacred learning from every part of the world. As We voice our wishes for a successful Congress and abundant fruits to follow from it, we express frankly our satisfaction at the particular character of this Congress and certain features with which it is intended to distinguish it. Its principal and definite purpose is to shed 6 POPE PAUL VI. a brilliant light on the person of John Duns Scotus, on his philosophical and theological doctrine, and his moral and ascetic principles. Avoiding the reefs of discussion and controversy which so often stood in the way in times gone by, the critico-historical method has been adopted in accordance with modern preferences, a method which, employed by learned men in discovering which are the genuine works of the Subtle Doctor and what are really and truly his teachings, has yielded excellent results. For this reason combined efforts are being made to produce the broad outline of a panorama, namely a unified vision of the whole family of the Scholastic doctors, in which it will be possible to measure and understand the variety, the richness, and the fecundity of the philosophical and theological doctrine which flourished in the Middle Ages. There is no doubt that in this panorama Saint Thomas Aquinas with his "Summa theologica" rises like a lofty peak dominating the mountains in the vicinity, that is, the whole world of sacred learning developed during his time. The synthesis created bythe Angelic Doctor in describing the relationship between Faith and Reason, between Faith seeking understanding (as your own Saint Anselm of Canterbury had already expressed it1) and understanding seeking Faith, achieved such universal agreement that he is recognised as leader in the ranks of the Scholastics and is rightly celebrated by the name of Doctor Communis. Side by side with him, however, other prominent Scholastic teachers and doctors stand out, like stars illuminating the Catholic learning of the period. In the encyclical letter Aeterni Patris, in which Our Predecessor of happy memory, Pope Leo XIII, pleads for the revival of Scholasticism under the leadership of Saint Thomas Aquinas in opposition to modern errors, after the statement that "Saint Thomas towers above all others",2 other Scholastic doctors are enumerated and a prominent place is reserved for Saint Bonaventure, whom Saint Pius X afterwards called "the second leader of Scholasticism",3 and it is universally recognised...

Abduction and metaphor are two significant concepts in cognitive science. It is found that the both mental processes are on the basis of certain similarity. The similarity inspires us to seek the answers to the following two questions: Whether there is a common cognitive mechanism behind abduction and metaphor? And if there is, whether this common mechanism could be interpreted within the unified frame of modern intelligence theory? Centering on these two issues, the paper attempts to characterize and interpret the (...) generation and evolution of scientific metaphors from the perspective of the cognitive mechanism of abductive inference. Then it interprets the common cognitive mechanism behind abduction and metaphor within Hawkins’ frame of intelligence theory. The commonality between abduction and metaphor indicates the potential to further explore human intelligence. (shrink)

Background: Informed consent in clinical research is mandated throughout the world. Both patient subjects and investigators are required to understand and accept the distinction between research and treatment.Aim: To document the extent and to identify factors associated with therapeutic misconception in a population of patient subjects or parent proxies recruited from a variety of multicentre trials .Patients and methods: The study comprised two phases: the development of a questionnaire to assess the quality of informed consent and a survey of patient (...) subjects based on this questionnaire.Results: A total of 303 patient subjects or parent proxies were contacted and 279 questionnaires were analysed. The median age was 49.5 years, sex ratio was 1 and 61% of respondents were professionally active. Overall memorisation of the oral or written communication of informed consent was good , and satisfaction with the process was around 70%. Therapeutic misconception was present in 70% of respondents, who expected to receive better care and ignored the consequence of randomisation and treatment comparisons. This was positively associated with the acuteness and severity of the disease.Conclusion: The authors suggest that the risk of therapeutic misconception be specifically addressed in consent forms as an educational tool for both patients and investigators.

Abstract. There is an ongoing debate in the philosophical and jurisprudential literature regarding the nature and possibility of Contract theory. On one hand, are those who argue (or assume) that there is, or should be, a single, general, universal theory of Contract Law, one applicable to all jurisdictions and all times. On the other hand, are those who assert that Contract theory should be localized to particular times and places, perhaps even with different theories for different types of agreements. This (...) article considers one facet of this debate: evaluating the relevance of the fact that the remedies available for breach of contract can vary significantly from one jurisdiction to another. This wide variation in remedies for breach of a (contractual) promise is one central difference between promises in morality and enforceable agreements in law. The article asserts that variation of remedies strongly supports the conclusion that there is (and can be) no general, universal theory of Contract Law. (shrink)

The current global ecological crises have, inter alia, led to an upsurge in massive migrations, food crises, diseases, pandemics, increased conflict and war especially in African societies. Most of those affected are the small farmers in rural communities who depend on agriculture. This crisis has not only raised concerns about the extent of the damage humans and human activities are causing to the natural environment but has also ignited discussions about the urgent necessity for a change in human behavior and (...) our obligations towards a new agrarian philosophy. In this chapter, I argue that Henry Odera Oruka’s Parental Earth Ethics could be adopted as a new principle of global justice and for grounding global environmental ethics. This principle invites us towards rethinking ecological fairness and global justice. Specifically, I opine that Oruka’s Parental Earth Ethics could be a veritable resource in our search for: (i) promoting global justice in the use and equal distribution of wealth and world resources for the common good and security of all, and (ii) global environmental ethics. It is basically driven by the ethical principle of the human minimum, which ought to inspire us humans to be more ethically and politically responsible in their use and distribution of world resources for the good and security of all.

In this paper, I make a case for an intercultural philosophy of religion from an African perspective. I focus on the philosophical underpinnings of the various meaningful religious practices and beliefs that give rise to the concepts of God, death and the problem of evil. A philosophical study of African traditional religions, based on anthropological findings across African cultural orientations, gives us a good starting point in understanding African worldviews and religious experiences. It also reveals that the various world religions (...) may all be seen as offering different perspectives on the same reality. Specifically, I argue that traditional African conceptions of God, death and the problem of evil could make significant contributions to global discourses in the philosophy of religion. First, I articulate points of convergence and divergence between African traditional religions with Saint Aquinas’ proofs for God’s existence; Second, I question the phenomenon of death and one’s life’s meaning. And third, I approach the problem of evil and attempt an African solution to the Epicurean dilemma. (shrink)

In this paper, I engage in a critical discussion of Francophone African philosophy focusing on its history, the influences, and emerging trends. Beginning the historical account from the 1920s, I examine the colonial discourses on racialism, and the various reactions generated leading to the Négritude movement in Francophone African intellectual history. I explore the wider implications of the debate on Négritude as an integral component of ethnophilosophy in postcolonial Francophone African philosophy. Finally, I argue that in spite of the apparent (...) linguistic divides/boundaries between Francophone African philosophy and the philosophical traditions in Anglophone and Lusophone Africa, there are robust interactions and critical exchanges of ideas converging and reconnecting with other philosophical orientations outside Africa. Keywords: African Philosophy, Colonialism, Francophone, Anglophone, Lusophone, Négritude, Ethnophilosophy. (shrink)

In this paper, I argue that traditional African communitarian values such as togetherness, mutual cooperation and solidarity are more consistent with the social structure and the political organization of many traditional societies in Africa and could be a veritable framework for implementing a program of inclusive development. I establish that African communitarian values take into consideration the contributions of all stakeholders, including the poor, vulnerable, and the marginalized in a bid to address development issues. I also provide strong reasons for (...) implementing communitarian strategies of togetherness, solidarity and mutual cooperation which support mutual interdependence and could promote inclusive development in Africa. I draw examples from traditional African ethic with communitarian values salient among small self-governing communities, and reflect on the ethic / politics of consensus in light of important developmental challenges facing the world today. I draw the conclusion that a critical and creative reevaluation of the communitarian values may help Africans and the rest of humanity in meeting the challenges of inclusive development.
