In his extensive work as a theologian and a historian, Walter H. Principe, CSB, (1922-1996) was committed to reflecting on both the present and the past. He was well-known as an historian of medieval theology and philosophy - especially through the work of Thomas Aquinas, as well as a contemporary theologian. This memorial collection addresses a fundamental feature of Principe's thought, namely his concern that the history of medieval theology and philosophy have a significant role to play in contemporary discussions. (...) Strengthening the ties between historical study and contemporary theological and philosophical thought, this book offers much to those who teach and research in historical theology and the history of philosophy. The ten essays provide significant test cases of how modern scholars may utilise the historical record judiciously for contemporary debates. Those who are concerned with intellectual history (both medieval and modern), the history of doctrines, and Thomism will also find this collection a useful contribution to modern scholarship.

The Century between the death of Copernicus and the birth of Newton witnessed a major reshaping of traditional ways of viewing the universe. The Ptolemaic system was challenged by Copernican heliocentrism, the Aristotelian world was assailed by Galilean physics and revived atomism, and theology was troubled by the progressive distancing of God from the daily operation of His creation. Besides earning this era the title of ‘the Scientific Revolution’, the intellectual ferment of these times offered many world systems as successors (...) to the throne of crumbling Aristotelianism.

In 1905 Albert Einstein, in a paper entitled “On the Electrodynamics of Moving Bodies”, as a solution to the disagreement between classical mechanics and the results of the Michelson's experiment, who showed the invariance of the speed of light in vacuum measured in different inertial reference systems, developed the theory of special relativity. In this essay Einstein expounded a theory that, instead of introducing a privileged system, required the revision of the concepts of space and time of classical physics. Combining (...) the principle of Galilean relativity, according to which the laws of physics are invariant in all inertial reference systems, with the physics of electromagnetism, according to which the speed of light in a vacuum is constant, Einstein concluded that time is no more than a relative measure, namely that whenever we have to do with speed equal to or close to that of light, time is no longer a variable absolute and independent of the reference system adopted, but depends on the variable position. This is what Einstein shows through the critical examination of the concept of simultaneity. The abandonment of the traditional conception of space and time based on the idea of a spatial continuum flowing through a temporal continuum coherently leads to the assumption of a space-time continuum in which distances and time intervals vary with the changing the reference system, and together vary, of course, all other sizes to those connected.

As reflexões metodológicas de Poincaré sobre a modelação mecânica dos fenômenos, as teorias físicas, a hierarquização das leis e a evolução do seu estatuto e sistema são susceptíveis de uma leitura kantiana que exibe a função constitutiva das matemáticas e a função reguladora dos princípios de conveniência e dos princípios da física, correspondendo estes a uma importante etapa na evolução das teorias físicas. The methodological reflections of Poincaré on the mechanical modeling of phenomena, physical theories, the hierarchy of laws and (...) the evolution of their status and system are illuminated by a Kantian reading that displays the constitutive function of mathematics and the regulative function of principles of convenience and of the principles of physics, these corresponding to an important step in the evolution of physical theories.

As fontes da pedagogia trabalhista de António Sérgio Resumo: Porventura o traço mais saliente da proposta educativa de António Sérgio para o Portugal republicano é a de ser uma pedagogia trabalhista, em que a preparação para e pelo trabalho é uma condição para a construção de pessoas autónomas, membros de uma sociedade baseada na cooperação. Para Sérgio, a correcta operacionalização dos novos métodos de ensino, valorizadores dos interesses imanentes das crianças, implicava uma fundamentação filosófica séria, um modelo antropológico coerente no (...) qual uma concepção do trabalho humano é fulcral. O propósito deste artigo é o de articular sinteticamente os fundamentos da sua proposta trabalhista do valor educativo e social de um ideal de trabalho, cuidando das fontes estrangeiras de inspiração da mesma, entre as quais destacaremos Pierre-Joseph Proudhon, John Dewey e Georg Kerschensteiner. Mostra-se que Sérgio soube encontrar uma fundamentação que junta reflexões daqueles pensadores, estabelecendo uma relação habitualmente ignorada entre os pedagogos seus, e nossos, contemporâneos. Pretende-se assim, recorrendo aos métodos da história das ideias, valorizadores da genealogia e da contextualização intelectual, homenagear, no cinquentenário da sua morte, um dos paladinos da Escola Nova em Portugal, dissipando algumas dúvidas sobre as reais motivações daquele Movimento pedagógico progressista no Portugal Republicano. Palavras Chave: António Sérgio. Pedagogia trabalhista. Proudhon. Dewey. Kerschensteiner. The sources of the labour pedagogy of António Sérgio: Perhaps the most striking feature of the thought of António Sérgio is his proposal of a labour pedagogy, where the preparation for and through work is a condition for the construction of persons that live in a society based on cooperation. For Sérgio the proper implementation of new teaching methods, that respect the true interests of children, implies a serious philosophical reflection, a coherent anthropological model in which a conception of human labour is critical. Our purpose is to articulate his philosophical reflections that justify the educational and social value of human labour, taking care of foreign sources of inspiration, among which are Pierre-Joseph Proudhon, John Dewey and Georg Kerschensteiner. It is shown that Sérgio brought together reflections of those thinkers, establishing a harmonic philosophical communion, usually ignored. By using the methods of the history of ideas that value the search of genealogy and intellectual context, we honour, in the fiftieth anniversary of his death, one of the paladins of the Éducation Nouvelle in Portugal, showing the real motivations of that progressive educational movement during the First Portuguese Republic. Keywords: António Sérgio. Labour pedagogy. Proudhon. Dewey. Kerschensteiner. Les sources de la pédagogie travailliste d’António Sérgio Résumé: Peut-être la caractéristique la plus frappante de la pensée éducationnelle d'António Sérgio est son pari dans une pédagogie du travail, où la préparation pour et par le travail est une condition pour la construction de personnes qui vivent dans une société fondée sur la coopération. Pour Sérgio, la mise en œuvre de nouvelles méthodes d'enseignement, qui respectent les véritables intérêts des enfants, implique une réflexion philosophique sérieuse, un modèle anthropologique cohérent pour lequel une conception du travail humain est essentielle. Notre but est d'articuler ses réflexions philosophiques qui justifient la valeur éducative et sociale du travail humain, en prenant soin des sources étrangères d'inspiration: Pierre-Joseph Proudhon, John Dewey et Georg Kerschensteiner. On démontre que Sérgio a rassemblé des réflexions de ces penseurs, en établissant une communion philosophique harmonique, généralement ignorée par les pédagogues et philosophes de son temps et du notre. En utilisant les méthodes de l'histoire des idées qui reconstruisent des généalogies et des contextes intellectuels, nous rendons hommage, dans le cinquantième anniversaire de sa mort, à l'un des paladins de l’Éducation Nouvelle au Portugal, en montrant les motivations réelles de ce mouvement éducatif pendant la Première République portugaise.

In 1677, Georges Pierre des Clozets visited Robert Boyle and told him that he had been approved for membership in the Asterism, a secret international society of alchemical masters, headed by Pierre's patron Georges du Mesnillet, the Patriarch of Antioch. Extensive correspondence followed, replete with gifts and bizarre claims, until Pierre vanished in August 1678. This paper links several new documents—articles in the Mercure galant and the Gazette de France and a manuscript account by another convinced admirer of Pierre—to my (...) previous study of him, particularly in regard to Pierre's claim to be working with the Patriarch to reunite Eastern and Western Churches. Dating from before and after Boyle's involvement, these sources add fresh details about Pierre and his other contacts, and show the consistency of Pierre's stories and the credibility he fashioned as he travelled around Europe convincing people of his claims alchemical and otherwise.

Cette étude montre que les réflexions épistémologiques de Poincaré émergèrent dans le cadre de ses recherches scientifiques et qu’elles furent en partie inspirées par sa lecture de savants philosophes comme Helmholtz et surtout Maxwell. Elle donne une analyse systématique des textes philosophiques publiés par Poincaré vers 1900, au moment où il juge que la physique des principes constitue le sommet de l’évolution des théories. Enfin, elle met en rapport certaines de ses thèses sur la physique avec l’Analytique et la Dialectique (...) transcendantales kantiennes. (shrink)

Can Lewisian counterpart theory adequately account for the deliberation involved in universalizing moral judgments? In this paper, the dispute between Shalom Lappin and Yehudah Freunlich over the answer to this question is examined and clarified. Then it is argued that Lappin andFreunlich do not join issue in a way which allows for satisfactory adjudication of their dispute. Specifically, they are unaware of the different models of role projection which each employs. By making these models explicit, it can be seen that, (...) regardless of how universalization is construed, a Lewisian can indeed offer an adequate account of moral deliberation. (shrink)

The question initially raised in this paper was on how one’s religious sensibility affects one’s response to suffering. Focusing on three particular disasters that hit the Philippines, we look at the various media sources: the writing about the rains and flooding found in broadsheets and online media, and some ethnographic descriptions coming from the social sciences; we also look at experiential or anecdotal sources. All this provides us with material to establish certain traits and topics that come to fore in (...) times of disaster, including such concerns as the lessons learned during disaster, the wrath of God, and points of cultural pride such as notions of solidarity and resilience. A significant upshot of this study has been the recognition of epistemic and methodological reevaluations that had to constantly be taken. This concludes in a retrieval of the contextuality of suffering, a redefinition of what it means to say that the response is a Christian one, and finally a proposal that paying closer attention to these points, in addition to non-philosophical sources, might be a way of rethinking the problem of suffering beyond the scope of traditional theodicies.

In lieu of an abstract, here is a brief excerpt of the content:AN IMPORTANT NEW STUDY OF THOMAS AQUINAS: JEAN-PIERRE TORRELL'S INITIATION A SAINT THOMAS D'AQUIN WALTER H. PRINCIPE, C.S.B. Pontifical Institute of Mediaeval Studies Toronto, Canada BEFORE BECOMING professor of theology at the Universite de Fribourg, Jean-Pierre Torrell, O.P., was a member of the Leonine Commission. This editorial experience, together with his continuing association with members of the commission, enables him in his new work, Initiation a saint Thomas d'Aquin: (...) Sa personne et son oeuvre, to clarify and frequently modify previous research conclusions about the life and work of Thomas Aquinas.1 Thus other recent studies in this area, e.g., those of James A. Weisheipl and Simon Tugwell, will have to be reassessed in the light of Torrell's findings in this important volume.2 Torrell, however, does more than examine the dates and places of Thomas's career and writing: as the book's subtitle and introduction make clear, his aim is to present the person of Thomas Aquinas in his context. This he does in a warm but measured fashion, situating Aquinas in his times, following Thomas's journeys about France and Italy on his intellectual apostolatea true ministry in the Dominican tradition-portraying him as 1 In the series Vestigia: Pensee antique et medievale 13 (Fribourg Suisse: Editions Universitaires; Paris: Cerf, 1993), pp. xviii, 592. 2 See Weisheipl, Friar Thomas d'Aquino: His Life, Thought, and Works, 2nd ed. (Washington, D.C.: Catholic University of America Press, 1983), and Tugwell, trans., ed., introd., Albert & Thomas: Selected Writings, The Classics of Western Spirituality (New York-Mahwah: Paulist Press, 1988), introd. [to Thomas Aquinas], pp. 201-351. 489 490 WALTER H. PRINCIPE, C.S.B. often nearly overwhelmed by the duties of this apostolate, yet vigorous and lively in defense of the faith and of the legitimate role of reason, a warm friend to many con,freres and others, a loyal and sometimes deeply involved member of his family. Torrell is especially adept at linking Thomas's apostolic activity with his profound and distinctive spirituality; this augurs well for Torrell 's promised companion volume, which will deal far more thoroughly with Thomas's spirituality than was possible within the editorial constraints of his earlier article in the Dictionnaire de spiritualite.3 New conclusions about the place and dating of Thomas's works Here, first, will be given a summary, with occasional comment, of this study's significant new conclusions about the place and dating of Thomas's works. Torrell accepts Weisheipl's view that Aquinas did his initial biblical commentary at Cologne before coming to Paris in 1252 and spent the years 1252-1256 working on the Scriptum super Sententiis. The "bref catalogue" at the end, prepared by G. Emery, O.P., states that this work is the "fruit of his teaching as bachelor of the Sentences at the begin;.. ning of his first stay in Paris ( 1252-54) ; its redaction had not yet been completed when he began his activity as Master ( 1256)" (485; emphasis mine). Weisheipl, with whom Torrell agrees as to Thomas's having done his cursory teaching of the Bible at Cologne, holds that Thomas lectured on the Senten:ces for the four years, 1252-1256 (71, 358); Tugwell seems to hold the same position when he speaks of Thomas "writing [his lectures on the Sentences] up for publication as he went" (211). Torrell's limitation of the teaching of the Sentences to 1252-1254 is based on the university statutes prescribing that this teaching be completed in two years (66), after which the candidate for the mastership would be a " formed bachelor " (baccalaureus formatus) whose main task would be to assist the master of 3 See his "Thomas d'Aquin," Dictionnaire de Spiritualite 15 (1991), cols. 718-73. INITIATION A SAINT THOMAS D1 AQUIN 491 theology with his disputed questions (58). This would mean that Thomas spent two whole years, 1254-1256, carrying out this rather minimal duty, redacting the Sentences (a task not completed until the beginning of his period as a master of theology), and composing two small works, the De ente et essentia and the De principiis naturae. Although the Scriptum is a... (shrink)

En 1705, Wilhem Homberg, le principal chimiste de l’Académie royale des sciences, proposa une nouvelle théorie chimique selon laquelle le Soufre principe des corps mixtes était identique à la lumière. Il affirma par la suite que cette lumière corporelle était la seule source d’activité et de changement dans les substances matérielles. Cet article montre comment la théorie de Homberg s’élabora progressivement pendant de nombreuses années sous l’influence de ses observations et des résultats de ses expériences de laboratoire, ce qui (...) nous fournit un exemple de la manière selon laquelle un chimiste du début du XVIIIe siècle a pu développer une théorie raffinée grâce à l’interaction de la réflexion et de la manipulation. L’influence probable de la théorie de Homberg sur les fameuses « questions chimiques » de Newton est également signalée ici pour la première fois. Enfin l’article avance que nous comprendrons plus précisément l’histoire de la chimie si nous reconnaissons le caractère spécifique de la chimie et sa relative autonomie, plutôt que si nous cherchons à lui imposer des développements faciles et convenus tirés d’autres champs du savoir comme la philosophie ou la physique.

Après 1850, la physique moléculaire laplacienne ou ampérienne s’est trouvée en compétition avec d’autres approches impliquant la thermodynamique et les théories cinétiques. Henri Poincaré est l’un des deux seuls savants français qui contribuèrent au développement de la mécanique statistique classique au tournant du siècle. Son ouverture à la physique étrangère et son engagement pour une physique des principes et pour un pluralisme méthodologique marquent une rupture avec l’autosuffisance prétendue de la physique française. Cependant, l’évolution des idées de Poincaré sur le (...) réductionnisme mécaniste ne peut se comprendre sans évoquer la cosmovision laplacienne, laquelle restait vivante vers 1880, à rebours d’une vision positiviste ou descriptive. Son apport à la mécanique statistique a des liens avec ce vieil engagement thématique des physiciens français, alors même qu’il s’ouvre aux idées de Maxwell et qu’il mobilise la mécanique céleste. Dans son cours sur la thermodynamique (1888-1889), il s’intéresse d’abord aux analogies mécaniques non-probabilistes proposées par Helmholtz pour les principes de la thermodynamique, en harmonie avec cette cosmovision. Vers 1893, il se rapproche des idées de Boltzmann et Maxwell et établit un rapport entre quelques résultats de mécanique céleste (récurrence, intégrales non-uniformes) et les fondements de la statistique. Il développe aussi un intérêt croissant pour les explications de l’irréversibilité thermodynamique. (shrink)
