This paper studies Bukharin’s Theory and Practice from the Standpoint of Dialectical Materialism presented at the 2nd International Congress of the History of Science in London, June 29–July 3, 1931. Bukharin’s paper has not received the attention it deserves despite the fact that it provides the theoretical framework for the paper mostly highlighted in this Congress, Boris Hessen’s The Social and Economic Roots of Newton’s Principia. In this work, I try to show that Bukharin’s main achievement is a theory of (...) science based on the concept of practice and at the same time present the internal coherence and the logical structure of Bukharin’s schema. Finally, I discuss what, in my opinion, is a drawback in Bukharin’s paper: his failure to discuss the possibility for scientific objectivity. (shrink)

We argue that, if taken seriously, Kripke's view that a language for science can dispense with a negation operator is to be rejected. Part of the argument is a proof that positive logic, i.e., classical propositional logic without negation, is not categorical.

This interview, conducted over the span of several months, tracks the respective journeys of Constantin V. Boundas and Daniel W. Smith with the philosophy of Gilles Deleuze. Rather than “becoming Deleuzian,” which is neither desirable nor possible, these exchanges reflect an array of encounters with Deleuze. These include the initial discoveries of Deleuze’s writings by Boundas and Smith, in-person meetings between Boundas and Deleuze, and the wide-ranging and influential philosophical work on Deleuze’s concepts produced by both Boundas and Smith. At (...) stake in this discussion are key contributions by Deleuze to continental philosophy, including the distinction between the virtual and the actual and the very nature of a “concept.” Also at stake is the formative or pedagogical impact of a philosopher, like Deleuze, on those who find and fully engage with his texts, concepts, and project. Cette interview, menée sur plusieurs mois, suit les parcours respectifs de Constantin V. Boundas et Daniel W. Smith avec la philosophie de Gilles Deleuze. Au lieu de « devenir Deleuzien, » ce qui n’est ni souhaitable ni possible, ces échanges reflètent un éventail de rencontres avec Deleuze. Il s’agit notamment des premières découvertes des écrits de Deleuze par Boundas et Smith, des rencontres en personne entre Boundas et Deleuze, et du travail philosophique vaste et in????luent sur les concepts de Deleuze produit par Boundas et Smith. L’enjeu ici étant les contributions clés de Deleuze à la philosophie continentale, y compris la distinction entre le virtuel et l’actuel, et la nature même d’un « concept. » Mais il y a aussi l’impact formateur ou pédagogique d’un philosophe, comme Deleuze, sur ceux qui trouvent et s’engagent pleinement dans ses textes, ses concepts et ses projets.

Does nostalgia for one’s time at university predict current intentions to engage with the university? In Study 1, United States participants’ nostalgia for their university experience (university nostalgia) at a southern public university predicted stronger intentions to socialize with fellow alumni, attend a future reunion, volunteer for their university, and donate money to their university. Study 2 replicated these findings with alumni from a northeastern private university, and extended them by finding that the links between university nostalgia and university engagement (...) emerged even when controlling for the positivity of university experience. In both studies, feelings of university belonging mediated most of the associations between university nostalgia and university engagement. In Study 2, the positivity of the university experience moderated the relation between university nostalgia and two indices of university engagement. Specifically, university nostalgia was more strongly associated with intentions to attend a reunion and donate money among those who had a relatively negative university experience. Nostalgia for one’s university past predicts future engagement with the university as well as its members. (shrink)

We dispute Henrich et al.'s analysis of cultural differences at the level of a narrow behavioral-expression for assessing a universalist argument. When Researchers Overlook uNderlying Genotypes (WRONG), they fail to detect universal processes that generate observed differences in expression. We reify this position with our own cross-cultural research on self-enhancement and self-esteem.

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

Le projet de Jean Piaget ne se réduit pas à son œuvre épistémologique. Il prend sa source, dès l'adolescence, dans une volonté de réconcilier la science et la foi. C'est de cette source-là, morale et humaniste, que lui vient son intérêt pour l'éducation. Sa pensée éducative se fonde sur la ferme conviction que la morale est une logique de l'action comme la logique est une morale de la pensée. Il s'ensuit qu'éducation morale et éducation intellectuelle doivent être menées de front, (...) et donc, qu'il faut éduquer la personne entière. Mais l'éducation est ambiguë par essence, selon qu'elle enferme l'enfant dans son égocentrisme intellectuel et la morale conventionnelle ou, au contraire, qu'elle stimule, par une pédagogie appropriée, sa marche vers une plus grande rationalité et une éthique personnelle. Dans de nombreux textes, Piaget explique comment l'école peut aider l'élève, citoyen de demain, à construire sa liberté intérieure, liberté de jugement autant que liberté de conscience. Humaniser l'humanité par l'éducation grâce à l'école, tel est le sens de son engagement - pendant trois décennies - à la tête du Bureau international d'éducation et à l'Unesco. (shrink)

The main novelty my article brings concerns a particular iconographic motif: that known as the ‘trial by the water of reproach’. In the few cases where this is rendered, usually only Mary is presented as undergoing this test, but in Cappadocian art Joseph is also subjected to it. Additionally, to this visual topic, another one that is rarely depicted will be introduced and commented upon: that known as ‘Christ’s first bath’. I will provide a particular example: the fresco which constitutes (...) part of the decoration that embellishes the walls of Karabaş Kilise/ ‘The Big Church’ in Soğanlı Valley, southern Cappadocia.

In the period between Constantine's reunification of the Empire in 324 and the deposition of Romulus Augustulus in 476 M. Valerius Probus enjoyed a large reputation as master of all areas of the ars grammatica. The commentary on Terence attributed to Donatus and the commentary of Servius on Virgil cite him more often than they do any other ancient authority. His fame persisted through the Dark Ages. Eugenius of Toledo set him with Varius and Tucca against Aristarchus, the greatest (...) of the Alexandrian students of Homer. Modern writers on the history of Roman scholarship have estimated in widely different ways his quality as a textual critic, the level of his reputation during the century after his death and the influence which his activities had on the transmission of the Latin classics. That he ‘annotated’ at least some of these in the manner of an Aristarchus is not in dispute, but everything about the nature of his ‘annotation’ is. This paper will treat afresh a famous statement about Probus in Suetonius' De grammaticis, two lists of notae associated with Probus’ name in a late eighth-century manuscript from Monte Cassino, cod. Paris, Bibl. Nat. lat. 7530, two references to such notae which have been detected in Virgilian scholia and a number of statements in these scholia which appear to give Probus’ reasons for affixing notae. The results of my study are largely negative but may help to control general discussion of the history of a number of Latin texts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Consistently Pro-Life: The Ethics of Bloodshed in Ancient Christianity by Rob Arner, and: Christ at the Checkpoint: Theology in the Service of Justice and Peace ed. by Paul Alexander, and: Becoming Nonviolent Peacemakers: A Virtue Ethic for Catholic Social Teaching and US Policy by Eli Sarasan McCarthyBrian D.

Taking as his point of departure the vigilante killing of abortion doctor George Tiller in Wichita, Kansas, in 2009, he argues not only that abortion is always morally impermissible but so also is [End Page 217] the murder of abortion doctors and the use of the death penalty to punish those who murder them. In addition, he turns to the early church fathers to contend that, prior to Constantine, “without exception, the church strongly condemned the taking of human life in any form whatsoever”—thus rejecting abortion and infanticide, the blood sport of the Roman games, suicide, and killing in war (120). This was because the New Testament witness to Jesus and his death on the cross required early Christians to view “the means as just as important, if not more important, than the ends” (xiii).Arner supplements this deontological argument for Christian pacifism, which he learned from John Howard Yoder, with a brief consideration of the virtue of patience cultivated in the early churches, reflecting the influence of Stanley Hauerwas on his thought. This “cardinal virtue” connoting “longsuffering, forbearance, patient endurance”—as found in Jesus’s teaching in the Sermon on the Mount (Mt 5:38–48)—enabled early Christians to practice non-violent resistance “deferring personal revenge in favor of God’s vindicating justice” (98). If Christians were to adopt this same consistently pro-life ethic today, argues Arner, it would “lead to greater healing and peace in our blood-soaked world” (121). The book closes with three appendices—one of which is a chart of terminology that dehumanizes vulnerable victims, including unborn human beings. Unfortunately, the book does not have an index.Christ at the Checkpoint, edited by Paul Alexander (professor of Christian ethics and public policy at the Palmer Theological Seminary of Eastern University), includes thirteen plenary addresses delivered at a conference on the Arab-Israeli conflict organized by Palestinian Evangelical Christians at Bethlehem Bible College in March 2010. Almost all of the contributors to this volume—including biblical scholars, theologians, ethicists, pastors, activists, and others—criticize the ideology of Christian Zionism and its support of a theology of dispensationalism that, in their view, distorts the scriptures and fosters violence rather than reconciliation between the Israelis and the Palestinians. In his own presentation titled “What Can Pentecostals and Charismatics Do for Peace with Justice in Israel and Palestine?,” Alexander—who describes himself as a former “one-sided” Christian Zionist who later discovered the writings of Yoder and Hauerwas—appeals to Jesus’s teaching in the Sermon on the Mount and urges Pentecostals to create church communities “that cultivate persons of character and conviction, who through habits, practices, and action live out the core of our faith” (69). Along with being faithful to the “greater challenges” of love, mercy, compassion, and forgiveness, he argues that they should publicly declare that Jesus does not want Israel to continue the occupation of Palestine, and they should engage in the “easier tasks” of promoting human rights, lending support to United Nations Resolutions, and working toward a two-state solution (72). “The time has come in human history,” writes Alexander, “for Pentecostals to speak and act prophetically regarding this present injustice … [End Page 218] and to use every nonviolent weapon in our arsenal—stories, preaching...

Ce deuxième tome des Hommes de la fraternité s'achève avec le règne de Constantin et le concile de Nicée (325). Les quelques deux cent cinquante évêques qui participent à ce concile dit " œcuménique " représentent bien mal, par leur provenance, ce qu'on appelait alors l'oïkouméné (l'ensemble des terres habitées). Mais le concile est présidé par l'empereur, et une ère nouvelle commence pour les chrétiens au sein de l'Empire. Ils sont si bien traités par le prince, ces évêques conciliaires, qu'ils (...) " se demandent s'ils ne sont pas déjà dans le Royaume de Dieu ". Il semble loin le temps de l'épître à Diognète (vers 195) qui parlait des chrétiens en ces termes : " toute terre étrangère leur est une patrie, toute patrie une terre étrangère. " avec Constantin s'inaugure ce qu'on appellera plus tard l'alliance du trône et de l'autel. Ce deuxième tome est celui d'un tournant décisif pour la suite de l'histoire. Mais l'historien qu'est Michel Clévenot se garde bien d'illustrer une thèse, fût-elle éclairante. Il donne au contraire à voir et à entendre la diversité des situations aux quatre coins de l'Empire et au sein des classes sociales si peu homogènes : le lecteur fait connaissance avec le " directeur de conscience " de la bourgeoisie d'Alexandrie, mais il visite aussi les petits agriculteurs d'Italie, d'Afrique du Nord ou des bords du Nil. Les querelles commerciales, les tensions économiques, les controverses théologiques, les affrontements politiques et guerriers, rien de tout cela n'est négligeable pour celui qui entend " l'appel de Jésus à ne pas déserter l'Histoire ".

This is a well written, clear, instructive, erudite book. The author begins with what he calls Ancient Catholicism, which reaches until the Alliance of Church and State under Constantine. Careful attention is given to Patristics, including of course the tremendous achievement of Augustine, the emergence of monasticism, the conflict of the Papacy with the Holy Empire and the East-West Schism. A special section is devoted to what Professor Burkill calls Medieval Developments in which he includes ecclesiastical structures and their (...) political involvements as well as the academic achievements of Scholasticism in its different forms. The analysis of the complexity of the Renaissance, from a humanistic, religious and political point of view, is in the opinion of this reviewer, impressively presented. Indeed these pages, with their factual and ideological content, are among the best. From this heap of facts and ideas arise certain common features which we would do well to remember, as for example, the frequency with which men have been willing to die for their convictions, whatever these happen to be. Every belief has its martyrs, and to hold this as a criterion of truth would be presumptuous. What strikes the reader furthermore in Burkill’s unbiased analysis is the tendency for the persecuted, once triumphant, to become in turn the persecutors. Persecution, religious no less than political, has unfortunately appeared to most if not to all, to be a means of survival. In the last section of his book, where Burkill deals with the last three hundred years, religious pluralism has become overwhelming. Burkill strives to do justice to all and yet to keep some form of unity. The book reaches unto modern times and the last name mentioned is that of Teilhard de Chardin. I should add one more remark. This book is not an apologetics. The author, partial to no one particular brand of Christianity, treats all with respect and objectivity. It is the work of an observer. If he does not reveal the beauty of religion "from within," neither does he deny it. This is not his purpose. Furthermore, although his historical approach is laced with philosophical observations, the book is not what might be called a philosophy of religion either, at least not explicitly. It is a survey written by a man who is both a philosopher and a theologican [[sic]], and in my opinion a very good one.—W. D. (shrink)

In 1883 Alexander Enmann demonstrated the existence of ‘eine verlorene Geschichte der romischen Kaiser’. Not all of his arguments or conclusions were valid, but one fundamental postulate is undeniable: Aurelius Victor in 359/60 and Eutropius a decade later independently used a common source, a lost Kaiser geschichte of relatively brief compass. This lost work went down to the death of Constantine in 337, and traces of it can also be discovered in other writings of the late fourth century: in (...) Festus’ Breviarium, in Jerome's revision of Eusebius’ Chronicle, in the Epitome de Caesaribus—and in the HA. If the HA used the Kaisergeschichte, its composition postdates 337— as Otto Seeck stated plainly in 1890. (shrink)

Ammianus Marcellinus, by common consent the last great historian of Rome, rounds off his obituary notice of the emperor Constantius II with the following observation: The plain simplicity of Christianity he obscured by an old woman's superstition; by intricate investigation instead of seriously trying to reconcile, he stirred up very many disputes, and as these spread widely he nourished them with arguments about words; with the result that crowds of bishops rushed hither and thither by means of public mounts on (...) their way to synods , and while he tried to make all their worship conform to his own will, he cut the sinews of the public transport service. This is a perceptive judgement of the ecclesiastical politics of the reign of Constantius, remarkable in a pagan writer, and of exceptional significance in that it lies outside those very ‘arguments about words’ which contaminate all the Christian assessments of this emperor. Although Ammianus is unsympathetic to Constantius, he manages succinctly to grasp the basic drift of imperial policy, inherited from Constantine himself, of trying to enforce the emperor's view of doctrinal and ecclesiastical unity by the summoning of repeated episcopal councils and browbeating the bishops into agreement — thus paying lip-service to the independence of the church's judgements. To the observant outsider, this process was notable above all for the burden it placed on the cursus publicus, as the bishops went about their business around the empire now provided with official evectiones; and Ammianus' comment finds confirmation in the letter issued by eastern bishops attending one of the many councils of Constantius' reign, that at Sardica in 343, who complained of the ‘attrition’ of the transport service caused by the imperial summons.

In lieu of an abstract, here is a brief excerpt of the content:Lorenzo Valla’s Oratio on the Pseudo-Donation of Constantine: Dissent and Innovation in Early Renaissance HumanismSalvatore I. CamporealeWhy did I write about the Donation of Constantine?... Bear one thing in mind. I was not moved by hatred of the Pope, but acted for the sake of the truth, of religion, and also of a certain renown—to show that I alone knew what no one else knew.Valla to Cardinal (...) Trevisan, 1443. 1Lorenzo Valla’s well known work, the Oration on the Falsely-Believed and Forged Donation of Constantine, was written by the humanist in the year 1440. It was occasioned by the strife between Pope Eugenius IV and Alfonso of Aragon over the Kingdom of Naples. Valla wrote in favor of the Ara-gonese claim, arguing against pretensions of the Papacy to determine who should rule Naples that were based on the pseudo-Constantinian Donation. 2 [End Page 9]The Donation of Constantine: History and ForgeryAs is now well known, the Constitutum Constantini was a forgery that probably originated in the papal Curia in the eighth century. Subsequently it was often contested by the anti-papal Germanic Imperial tradition. The Constitutum portrayed the popes as assuming the role of the Emperor in the western part of the Empire as a result of the “donation” made by Constantine to the “Roman Pontiff and his successors.” The Donation was said to have taken place at a time subsequent to Constantine’s seizure of the city of Rome with the victory at the Milvian Bridge in a.d. 312, and immediately after his “conversion” to the Christian faith and his “reception of baptism” by the bishop of Rome, Pope (“Saint”) Sylvester.The Constitutum presents itself as an imperial decree, drafted and signed by Constantine himself, dated in Rome with an ambiguous formulation which could indicate the year 315 or 317 or even 330. The most significant and comprehensive passage of the entire document reads as follows:In order that the supreme pontificate may not deteriorate, but may rather be adorned with glory and power even greater than the dignity of earthly rule, behold, we give over and relinquish to the aforesaid our most blessed Pontiff, Sylvester, the universal Pope, our palace, as has been said, and also the city of Rome, and all the provinces, places and cities of Italy and the western regions, and we decree by this our godlike and pragmatic sanction that they are to be controlled by him and by his successors, and we grant that they shall remain under the law of the Holy Roman Church. 3The forgery was based an on older fictional source, the Legenda Sylvestri. It was later (at least as maintained first by Nicholas of Cusa, then by Valla) introduced by the canonist Paucapalea (Gratian’s disciple and collaborator) into the collection of canon law that had been made by Gratian, the Concordantia discordantium canonum, or Decretum (c. 1140). 4 Assertions that the Constitutum derived from the Legenda and that it was a later [End Page 10] insertion into the Concordantia represent discrete stages of Valla’s philological procedure. In fact Valla’s argumentation evolves in a kind of concentric movement. After discussing the hagiographic “fiction” of the Legenda, he treats the canonical “inauthenticity” of the Constitutum as a later insertion into the Concordantia. Then Valla returns to the notion that it was “made up” or “fictional” when he declares the Constitutum a juridical “forgery.” 5Valla’s Methodology and Argumentative ProcedureThe Oratio—this was how Valla titled his work—is a confutative discourse, rhetorically structured in the epideictic mode, although particular passages also assume forensic and deliberative modes. The oration was written in accordance with rhetorical norms for investigation and argumentation that Valla had learned from and elaborated on the Institutio oratoria of Quintilian, the writer Valla considered preeminent in the rhetorical tradition. 6“This speech of mine,” Valla emphasizes, is a speech intended for and offered to the universal assembly of Christendom. Although directly addressing the Papacy and in particular the ruling pope, Eugenius IV, the “oration” is conceived as though delivered in the presence of both the ecclesiastical hierarchy and civil authorities (“quasi...

In this paper two models for movement of respiratory gases in the insect trachea are presented. One model considers the tracheal system as a single flexible compartment while the other model considers the trachea as a single flexible compartment with gas exchange. This work represents an extension of Ben-Tal’s work on compartmental gas exchange in human lungs and is applied to the insect tracheal system. The purpose of the work is to study nonlinear phenomena seen in the insect respiratory system. (...) It is assumed that the flow inside the trachea is laminar, and that the air inside the chamber behaves as an ideal gas. Further, with the isothermal assumption, the expressions for the tracheal partial pressures of oxygen and carbon dioxide, rate of volume change, and the rates of change of oxygen concentration and carbon dioxide concentration are derived. The effects of some flow parameters such as diffusion capacities, reaction rates and air concentrations on net flow are studied. Numerical simulations of the tracheal flow characteristics are performed. The models developed provide a mathematical framework to further investigate gas exchange in insects. (shrink)

The present monograph is devoted to the principal problems of quantum mechanics and is based on the conception first stated in my course on 'Fundamentals of Quantum Mechanics'. The scope and purpose of the above course did not allow some principal questions to be brought out as fully as they deserved, and besides, some important points were only very recently developed to a sufficient extent. This refers especially to the analysis of the action of the measuring instrument, whose dual role (...) as an analyser of a quantum ensemble and as a detector of individual events was insufficiently elucidated. The reader will find that the present monograph is concerned more with theoretical physics than with philosophy. However, I have never separated Weltanschauung from science (and particularly theoretical physics) so that the philosophical implications are also discussed, justi fying publication in the philosophical series. In conclusion, I should like to thank the publisher and the translator, whose initiative and effort have made it possible for the book to reach the English-speaking reader. (shrink)

P¯an.ini’s grammar includes several types of metarules which determine how its operational rules apply. Among them are “traffic rules” which constrain how rules interact with each other in grammatical derivations. These are typically formulated as designating a rule or class of rules asiddha “not effected” (or asiddhavat “as if not effected”) with respect to another rule or class of rules. For economy, the rules so designated are grouped into several sections, whose headings collectively declare them to be asiddha(vat). The biggest (...) such section, under the famous heading 8.2.1 p ¯urvatr¯asiddham, extends from 8.2.1 through the end of the grammar (8.4.68), and is hence called the Trip¯ad¯ı ‘Three Sections’.

First collected in Italy in 1985, _Art's Claim to Truth_ is considered by many philosophers to be one of Gianni Vattimo's most important works. Newly revised for English readers, the book begins with a challenge to Plato, Aristotle, Kant, and Hegel, who viewed art as a metaphysical aspect of reality rather than a futuristic anticipation of it. Following Martin Heidegger's interpretation of the history of philosophy, Vattimo outlines the existential ontological conditions of aesthetics, paying particular attention to the works of (...) Kandinsky, which reaffirm the ontological implications of art. Vattimo then builds on Hans-Georg Gadamer's theory of aesthetics and provides an alternative to a rationalistic-positivistic criticism of art. This is the heart of Vattimo's argument, and with it he demonstrates how hermeneutical philosophy reaffirms art's ontological status and makes clear the importance of hermeneutics for aesthetic studies. In the book's final section, Vattimo articulates the consequences of reclaiming the ontological status of aesthetics without its metaphysical implications, holding Aristotle's concept of beauty responsible for the dissolution of metaphysics itself. In its direct engagement with the works of Gadamer, Heidegger, and Luigi Pareyson, _Art's Claim to Truth_ offers a better understanding of the work of Vattimo and a deeper knowledge of ontology, hermeneutics, and the philosophical examination of truth.
