Some twenty years after the Gregorian calendar reform, towards the end of his life, François Viète published his own calendar proposal. This treatise contains a sharp attack against the Jesuit scholar Clavius, the mathematical mind behind the reform. Understandably enough, Clavius prepared a negative reply. Viète heard of it and exploded in a fit of rage, ``I demonstrated that you are a false mathematician [... ], and a false theologian.'' Sadly, Clavius' rejection, added as a chapter to his monumental (...) apology of the Gregorian reform, appeared when Viète had already passed away.Viète seriously believed that the true aim of the Gregorian reform has been betrayed and he was furious about some logical inconsistencies which he claimed to have found in Clavius' calendar. Clavius apparently confused solar day and epactal day (or ``tithi''), the thirtieth part of a lunar month. This is the very core of Viète's attack against Clavius whom he accused of having introduced a false lunar period (``falsa periodus lunaris''). But his own work has some logical inconsistencies too. For instance, he reproaches Clavius for having introduced lunar months of 31 days which, indeed, are unrealistic. Grievously, his own rules can likewise give rise to lunations of unnatural lengths.In order to understand these subtle twists reader and author must work largely through both Clavius and Viète's methods of Easter reckoning. The fruit of all those efforts might be an insight into Viète's clear mathematical thinking. His calendar, however, was never considered. (shrink)

These techniques can be used to persuade others—colleagues, editors, publishers, and research integrity committees—when academic plagiarism has been committed.

Katelis Viglas’ book: Jeremiah II Tranos. Archbishop of Constantinople, New Rome and Ecumenical Patriarch (1536-1595) is a historical-theological description and analysis of the most important data and facts concerning the life and works of Jeremiah II Tranos, Patriarch of Constantinople in the 16th century. The book consists of a Prologue, which refers to the aim of the treatise and the method followed. In the Introduction there is a general outline of the era of Jeremiah II and its origins, as well (...) as a brief presentation of his contribution to the Greek Genus. The First Chapter is divided into three subchapters. The first subchapter provides a brief overview of the history of the birthplace of Jeremiah II, Anchialos, a city on the shores of the Black Sea, and describes patriarch’s character and education, along with an extensive reference to his teachers. In this subchapter information is included relative to Jeremiah’s life until his ordination as Metropolitan of Larissa. The second subchapter briefly narrates the glorious ordination of Jeremiah II to Patriarch of Constantinople. In the third subchapter of the First Chapter, the three breaks during Jeremiah II’ patriarchate –caused by the selfish ambitions of his competitors, who coveted the patriarchal throne– are recounted. The Second Chapter consists of four subchapters. In the first subchapter there are a brief reference to the life and religious beliefs of the founder of the Reformation, Martin Luther, and the interest and curiosity of the Lutherans in the situation of the Eastern Orthodox Church. The second subchapter of the Second Chapter contains biographical details of the Protestant scholar and philhellene Philip Melanchthon, and a reference to the first contact attempt of Lutherans with the Patriarchate of Constantinople. The third subchapter of the Second Chapter is divided into six other subsections. The first section of the third subchapter describes the way the relationships of the Lutheran theologians of Tubingen with Patriarch Jeremiah II developed and to the starting point of their correspondence. Yet, the Philhellenism of the German Hellenist Martin Crusius and the role he played in the correspondence are highlighted. The second section outlines Jeremiah II’ responses to each article of the Augsburg Confession send to him by the Tubingen theologians. The third section highlights the key points of the reply of the Tubingen theologians to the First Answer from Jeremiah II. The third section refers to the Second Answer from Jeremiah II. In the short fifth section there is a reference to the reply of the Tubingen theologians to the Second and the Third Answer from Jeremiah II. The sixth section provides information related to the publication of that correspondence. In the fourth subchapter of the Second Chapter there are general and evaluative judgments on the correspondence between Jeremiah II and the Tubingen theologians. The Third Chapter is divided into five subchapters. The first subchapter explains the ancient Roman calendars of Numa and Julius Caesar and their shortcomings. The second subchapter presents the findings of these imperfections by various scholars. The third subchapter describes the Gregorian Reform of the calendar. The fourth subchapter analyses the social situation within the Orthodox Church during the Gregorian Reform. The fifth subchapter aims to show the orthodox reaction of Jeremiah II to the Gregorian calendar and its causes. The Fourth Chapter is divided into two subchapters, of which the first is related to Jeremiah’s travels in Poland and the regulation by him of Church life in this country, while the second gives an overview of the circumstances, under which the foundation of the Russian Patriarchate took place. The Fifth Chapter is divided into three subchapters. The first subchapter examines Jeremiah II’s concern on various issues. The second subchapter deals with Jeremiah II’ concern on the education of the Greek Genus. The third subchapter explains the attitude of Jeremiah II towards the Pontifical Greek College in Rome. At the end of the treatise there is an Epilogue, with concluding remarks on the evaluation of the historical figure of Jeremiah II, his spiritual identity and the status of the Orthodox East under his leadership. An extensive Bibliography, a Chronology, an Index of Names, 21 Illustrations and 2 Maps, complete the book. (shrink)

Dans l’Europe médiévale, l’art de la guerre est considéré comme spécifiquement masculin. Et pourtant, au détour des chroniques et des documents d’archives, il est possible de croiser des guerrières qui combattent pour défendre leurs fiefs ou s’engagent parmi les rangs des croisés. Cette pratique de la guerre au féminin, très minoritaire, mais avérée, reposait-elle sur un droit, ou, bien au contraire, bravait-elle toutes les interdictions des lois civiles et religieuses? Si le droit civil l’interdit, la réponse de l’Église semble parfois (...) plus ambigüe. C’est le cas aux xie et xiie siècles où, dans le cadre de la Querelle des Investitures, la comtesse Mathilde de Toscane est à l’origine d’une polémique qui a vu s’opposer les partisans de la réforme grégorienne à ceux de l’empereur Henri iv et qui s’est précisément cristallisée sur cette question : les femmes ont-elles le droit de faire la guerre?

In lieu of an abstract, here is a brief excerpt of the content:Objective Reality of Ideas in Descartes, Caterus, and Su irez NORMAN j. WELLS IT HAS LONG BEEN ACKNOWLEDGEDthat Francisco Sufirez's distinction between a formal and an objective concept exercised some influence upon Descartes's teaching on 'idea'.' It would appear, however, that not enough attention has been given to that distinction of Sufirez (and especially to another to be mentioned shordy) to aid in dispelling what I take to be (...) a widespread confusion and misunderstanding with regard to 'idea' in Descartes, especially with respect to 'idea' taken 'objectively'. Much, if not all, of the confusion in question has to do with Descartes's admittedly equivocal use of the term 'idea'. For he had allowed that 'idea' could be taken 'materially' (materialiter), on the one hand, for the knowing activity of the intellect. On the other hand, it could be taken 'objectively' (objective) for the thing (res) represented by that knowing activity.' At this point, the contemporary reader can only be brought up short, See E.

The [33] 34 JOURNAL OF THE HISTORY OF PHILOSOPHY 28"1 JANUARY 1990 conditioned as we are by an appreciation of 'objectivity' altogether extramental! It makes for a considerable wrench of perspective to do justice to Descartes's acknowledged doctrine of intramental objectivity and an intramental 'thing represented' (resrepraesentata). 'Idea', then, in traditional Cartesian fashion, designates the act of representing as well as the 'thing represented '. S Yet, for all this, and despite repeated expressions of the same doctrine, there is a persistent tendency in the history of Cartesianism and its scholarship to interpret 'idea' taken 'objectively' as in some way representative. Contrary to what I take to be Descartes's constant position, such a rendering unwittingly transfers that function which is proper to the cognitive activity, mind is the efficient cause of its cognitive activity. With respect to ideas taken 'objectively', such as the ideas of God and the triangle on the levels of metaphysical and mathematical intelligibility, an efficient cause, extrinsic to the mind, is certainly at issue. For here we are in the presence of what is independent of the mind, however intramental it may be. On the triangle, see Medit. 5; 7: 64. ]4s7 : "...est tamen profecto determinata quaedam ejus natura, sire essentia, sive forma, immutabUis et aeterna, quae a me non efficta est, nec a mente mea dependet."

Divine inspiration through the Holy Ghost is topical in the portraits of Gregory the Great: A dove brings him the divine words, which he writes himself or dictates to his deacon Petrus. Thus the charismatic Father of the Church became, like the Evangelists, a divinely inspired medium who transmitted the mandate of spreading the gospel and guaranteed the heavenly origin of the texts that were recited and sung in the liturgy. The preface ‘Gregorius presul’, which is to be found in (...) variant forms introducing antiphonaries and cantatories, states that Gregory, the “powerful teacher” of church chant, composed the songbooks (composuit hunc libellum musicae artis), thereby sanctifying them. Scholars see in this preface a Carolingian strategy of legitimation based on this dynasty’s theocratic concept of power. Gregorian chant, the quintessence of medieval monophonic tradition, has his origins in the Frankish church adopting the “authentic” Roman rite, which was declared canonical liturgy in all churches of the Frankish empire because of Gregory’s authorship. But the consolidation of Gregory’s myth unintentionally legitimated the process of composition, too, because the connection between the concepts of authorship and inspiration justified the composer’s claim to the ministry of spreading the gospel and of attaining the highest knowledge.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 157-161 [Access article in PDF] Book Review Toward a Christian Theology of Religious Pluralism Toward a Christian Theology of Religious Pluralism. By Jacques Dupuis, S.J. Maryknoll, New York: Orbis Books. 1997. xiv + 433 pp. There may not be another individual more qualified than Jacques Dupuis to write this book. He has not only spent a lifetime teaching and serving in a part of the (...) world where the encounter between Christianity and other faiths has been particularly pressing (India), but he has also previously reflected intensively and published widely on this topic. Even more impressive, however, is the fact that the scholarship that emerges in this volume reflects Dupuis as a faithful Catholic Christian, both in the sense of paying sincere heed to the wide range of the Roman Church's official teachings on this and related topics (he taught for years at the Gregorian University in Rome and edited, with Josef Neuner, the massive The Christian Faith in the Doctrinal Documents of the Catholic Church 1 ) and in the sense of thinking along with others in the universal community of faithful Christians. Here we have a master theologian practicing his craft, working within a community of theological inquirers, bringing out, displaying, and putting to work old things and new in the effort to understand one of the most crucial issues of our time.The result is a comprehensive and lucid discussion of Christian theology of religions that is indispensable as an introduction to students without any knowledge of the landscape even while it also serves as a handy status questionis to those already [End Page 157] familiar with the terrain. The first half of the book (part 1) is an overview of the history of Christian approaches to other faiths, beginning with the biblical material, continuing through the Logos spermatikos theology of the early Fathers, the developments surrounding the Extra ecclesiam nulla salus ("no salvation outside the Church") axiom over the centuries, and the pre- and post-Vatican II attempts to develop a theology of religions in the Catholic Church. This part concludes by summarizing the paradigm shifts from ecclesiocentrism to (in order) christocentrism, theocentrism, and regnocentrism/soteriocentrism. Throughout the discussion--especially of the pre-twentieth-century history that focused much more so on the fate of the unevangelized--Dupuis manages to provide important connections to developments in Christian thinking about the role of the religions in the divine scheme of things.The second half of the volume (part 2) presents seven of the most difficult theological questions in Christian theologia religionum today. First, concerning the covenant: is there only one, or are there many? Is salvation history particular, or universal? Dupuis' provisional response is that there is one cosmic covenant that is never revoked. This covenant is revealed according to what he calls a "trinitarian rhythm" whereby God covenants through his Word, in his Spirit, and this covenant includes the witnesses of God left in other religions as well. Second, concerning revelation: does revelation come to us from "without," or emerge from "within" ourselves? What about the sacred texts of other traditions? How are Christians to understand the fullness of the revelation in Jesus Christ vis-à-vis other faiths? Dupuis' answer is that divine revelation is indeed scattered among the various religions, even if fully captured only in Christ, and that these revelations are thereby differentiated but complementary. 2 Third, concerning the divine mystery: is the "Real" beyond the categories of "personal" and "impersonal"? Is God one, or many (triune)? Dupuis responds that the religions have complementary and converging insights into the divine reality. Fourth, concerning Jesus Christ: is he one among many savior figures? What does the uniqueness of Christ mean? Is there a distinction or an absolute identity between Jesus and Christ? Is the Christ particular, or universal? Dupuis posits a "searching christology" whereby God reveals Godself in and through the images and symbols of the religions and through which humankind therefore responds to the divine graciousness. Jesus' uniqueness is thereby both "constitutive" (of universal significance) and "relational" (inserted in the overall plan of... (shrink)

This essay analyzes the work of Paolo Prodi (1932–2016), which is characterised by a constant reflection on secularisation. As a democratic Catholic, he explored the relationship between the Roman Church and the modern world starting from the Council of Trent and from the dual figure of the pope as a temporal ruler and spiritual guide. His original contribution concerned the conflict between law and conscience: a problem that led him to design a triptych of books on the foundations of the (...) western world. He was influenced not only by Verfassungsgeschichte (German constitutional history), but also by Harold Berman. If for Weber the modern world was born from the Reformation, for Berman it was the ‘Gregorian revolution’ that changed the fate of Latin Europe. For Prodi, too, the medieval conflict between canon and civil law introduced a peculiar structure in Europe that would last until the triumph of the nation states and the so-called ‘political religions’. In his three books (the first dedicated to the oath, the second to justice, the last to economics), Prodi placed at the centre of his analysis the notion of forum; the history of moral theology and casuistry and the relationship between penitence and justice.

Although most natural law ethical theories recognize moral absolutes, there is not much agreement even among natural law theorists about how to identify them. The author argues that in order to understand and determine the morality (or immorality) of a human action, it must be considered in relation to the organized system of human practices within which it is performed. Such an approach, he argues, is to be found in the natural law theory of Thomas Aquinas, especially once it is (...) recognized that the logical structure of Aquinas's ethical theory is basically that of an Aristotelian science. In order to depict this structure and to explain how it bears upon the analysis of action, the author investigates a number of issues that have attracted the attention of Thomistic and Aristotelian scholarship. He examines the nature of practical reason, its relationship with theoretical reason, the derivation of lower from higher ethical principles, the incommensurability of human goods, the relationship between will and intellect, and the principle of double effect. The book will be useful to students and scholars interested in ethics, especially from an Aristotelian and/or Thomistic perspective. One appendix reproduces the Leonine text of the De malo (question 6), with facing English translation. Another appendix provides facing Latin text and English translation of the Summa Theologiae I-II (question 94, article 2). ABOUT THE AUTHOR: Kevin L. Flannery, S.J., author of many works on the history of logic--particularly Aristotelian logic--is dean of the faculty of philosophy and professor of the history of ancient philosophy at the Pontifical Gregorian University in Rome. PRAISE FOR THE BOOK: ""I know of no more careful and detailed study of Thomas's principle that the realms of theoretical and practical rationality are parallel. This principle is indeed central to an understanding of Thomas Aquinas's ethical thought, and Father Flannery examines its ramifications most perspicaciously. His book constitutes a valuable and important addition to the Thomistic literature. Father Flannery's writing is lucid, if not always extremely engaging, and his arguments are well supported by references to, and quotations from, the Aristotelian and Thomistic texts upon which they are based.""--The Medieval Review ""It would be hard to overstate the importance of this book at the present juncture of Thomistic studies.""--Ralph McInerny, University of Notre Dame ""... of interest and of great value mostly to specialists in Aquinas's ethics or moral theory more generally. Flannery presents complex matters clearly, and his explanations of the logical presuppositions of Aquinas's moral thought are always illuminating.""--Jean Porter, Theological Studies ""This is a significant work that belongs on the bookshelf of any serious student of Aquinas.... An important contribution to Thomistic studies.""--Irish Theological Quarterly ""This scholastic text will particularly appeal to thinkers interested in Aristotelian mathematics and logic and their practical integration into Thomistic natural law ethics. However, all natural law scholars must address the questions of context and method raised by Flannery's insights and his careful, precise textual analyses."" -- Beverly Whelton, Review of Metaphysics.

Macphail’s ‘null hypothesis’, that there are no differences in intelligence, qualitative or quantitative, between non-human vertebrates has been controversial. This controversy can be useful if it encourages interest in acquiring a detailed understanding of how non-human animals express flexible problem-solving capacity (‘intelligence’), but limiting the discussion to vertebrates is too arbitrary. As an example, we focus here on Portia, a spider with an especially intricate predatory strategy and a preference for other spiders as prey. We review research on pre-planned detours, (...) expectancy violation and a capacity to solve confinement problems where, in each of these three contexts, there is experimental evidence of innate cognitive capacities and reliance on internal representation. These cognitive capacities are related to, but not identical to, intelligence. When discussing intelligence, as when discussing cognition, it is more useful to envisage a continuum instead of something that is simply present or not; in other words, a continuum pertaining to flexible problem-solving capacity for ‘intelligence’ and a continuum pertaining to reliance on internal representation for ‘cognition’. When envisaging a continuum pertaining to intelligence, Daniel Dennett’s notion of four Creatures (Darwinian, Skinnerian, Popperian, Gregorian) is of interest, with the distinction between Skinnerian and Popperian Creatures being especially relevant when considering Portia. When we consider these distinctions, a case can be made for Portia being a Popperian Creature. Like Skinnerian Creatures, Popperian Creatures express flexible problem solving capacity, but the manner in which this capacity is expressed by Popperian Creatures is more distinctively cognitive.

In the Cairo Genizah were manuscripts with Gregorian notation and Hebrew script. They also appeared documents that point to author of the scores at Giovanni-Obadiah, a twelfth century Christian monk, born in southern Italy, who converted to Judaism. Until now, the study of this personage has been realized almost exclusively from the Jewish point of view. Nevertheless, like Obadiah synthesizes the traditions Christian and Jewish in its notation when copying Hebrew melodies with Christian notation, also it does in his (...) texts. Obadiah transcribed a Latin appointment of Joel to Hebrew characters. This article pretends to oppose his conversion to Judaism with his ordination as a Christian monk through the prophecy of Joel, which implies an intense dialogue between the two traditions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The 2005 Meeting of the Society for Buddhist-Christian StudiesFrances S. Adeney, SecretaryThe annual meeting of the Society for Buddhist-Christian Studies was held in Philadelphia on November 18, 2005. The theme of the program was visual and aural expressions in Christianity and Buddhism and their relationship to religious practice.The focus of the first session was visual images of sacred art. Victoria Scarlett presented the paper "The Iconography of Compassion: Visualizing (...) Guanyin and the Virgin Mary." She noted that meditation exercises that explore visual imagery can mediate the experience of the holy in both Buddhism and Christianity. By comparing and contrasting the images of Guanyin and the Virgin Mary through both commentary and slides, she pointed toward the qualities of compassion, healing, empathy, generosity, and selfless love presented in both Buddhism and Christianity. Scarlett stressed the role of visualization in generating compassion and taking responsibility for cultivating and living the devotional life. Engaging the religious imagination in those visual ways, she said, can help us generate compassion in our world today.Alice Keefe presented the second paper, "The Visual Dimension of Religion in Comparative Perspective." She challenged the assumption that visual experience is a derived or secondary aspect of religious life. As Tibetan Buddhism clearly shows, through its depiction of Buddhas, lamas, bodisattvas, and deities, the divine is form as well as formless. In Christian Orthodox traditions, the icon is viewed as material and glory, the transcendent visible to the human eye. Visual images in both Buddhist and Christian traditions indicate the possibility of transformation as one imagines one's own body as a body of light.Keefe challenged us to bring the centrality of the visual in Buddhism and some portions of Christianity into our academic discussion. Western thinkers present the body in opposition to the spiritual, sometimes understanding images as idolatrous. We assume that the generative locus of meaning is in the subjective consciousness and seek out ideas, ignoring the body. However, communicating an idea is not the [End Page 181] object of visual attention to an icon—rather, it involves the constitution of a self in relation to others. Through practices that activate the visual dimension of religions, we come to know ourselves as part of a pantheon of beings.Rita Gross responded to both papers, focusing on the biases of Western religion in the study of Buddhism. The prohibition of idolatry in Western religion has been identified with the sense of sight, rather than hearing or the use of words. Furthermore, idolatry is always a category defined by outsiders, Gross asserted. People who use the sense of sight to reach beyond themselves to the sacred know what they are doing. The papers and visual images presented gave the attendees insight into how that might happen in Buddhism and Christianity.Michael Monhart and Jisho Shizuka opened the second session with their presentation of "Chanting as Practice: Japanese Shingon Buddhist Sutra Chant." After a brief history of the Shingon sect, the presenters focused on a central aspect of Shingon chanting practice: a realization of one's inherent Buddha-nature in this life. Through activating the mysteries of the ritual activities of the body, voice, and mind, chanting develops the specific connection between Buddha-nature and human nature. An explanation of the chanting itself—its modes, patterns, and energies—led to the conclusion that sound and word become reality through their use by the practitioner of ritual, a conclusion that was demonstrated by the chanting of three sutras.Bill McJohn and Joseph Anderson next presented their work, "The Aural Dimension of Religion: Chanting Psalms in Gregorian Chant." McJohn focused on the history of chanting the Psalter, beginning in the monasteries of the fourth century. Singing the Psalms was motivated by a desire to pray constantly, and as the monastic communities developed, a practice of working through the 150 psalms developed. A shorter version, which eventually became the rosary, also developed. Anderson noted that the recitation of the Psalms is the analog to Buddhist chanting of the sutras. One is actually speaking as the Christ in recitation of the Psalms. Both also find a balance between time and timelessness as they are re-created in different ways... (shrink)

Father Jakub Gorczyca, a Polish Jesuit, is a professor of philosophy at the Gregorian University in Rome. The subject of his particular concern is the set of problems encountered in philosophical anthropology, fundamental ethics and the philosophy of religion. Gorczyca draws philosophical inspiration from the intellectual tradition of Christianity, from phenomenology, and from the philosophy of dialogue.

This paper examines the purport of epact tables encountered on scientific instruments, and explains their use. The epact is a valuable chronological aid for calculating the age of the moon. In handbooks of chronology, usually two types of epacts are distinguished: the epact used in medieval times, and the so-called Lilian epact used after 1582 in the Gregorian perpetual calendar. By examining the rules for calculating the age of the moon, it turns out that the Julian and Gregorian (...) epacts encountered on instruments must be distinguished from the medieval and Lilian epacts. It is shown that the Julian epact was already in use in 1478, and that, by adjusting for the shift of ten days in the date of the vernal equinox, the Gregorian epact was derived from it in 1582. The common association of the latter with the Lilian epact employed in the Gregorian perpetual calendar is incorrect. It is further shown that in contrast to the medieval and Lilian epacts, which served purely ecclesiastical purposes, the Julian and Gregorian epacts were mainly used to calculate the true age and zodiacal position of the moon. This knowledge was applied to secular interests such as ‘lunar astrology’, tidal computations, and the conversion of lunar into solar time. (shrink)

We discuss the astronomical underpinning of the improved calendar of 1700. Starting from the astronomical motivation of the Gregorian calendar of 1582 and the rejection of this reform in Protestant states in Europe, we describe how the astronomical Easter reckoning based on Kepler’s Rudolphine tables led to the foundation of Berlin Observatory and enabled the founding of the Electoral Brandenburg Society of Sciences, which had to finance itself through a calendar monopoly.

In lieu of an abstract, here is a brief excerpt of the content:Montaigne on Witches and the Authority of Religion in the Public SphereBrian RibeiroThe pleasure in reading Michel de Montaigne, the French Counter-Reformer and fideistic skeptic, is due in no small part to the ways in which he so frequently defeats our expectations. The surprises occur at several levels, beginning with the very titles of his essays, which frequently have little to do with the topics he actually discusses. Who, (...) for example, would expect an essay titled "Of Three Good Women" (II.35) to praise the three women for their variously successful attempts at committing suicide—and little else? Or who would expect an essay with the innocent title "On Some Verses of Virgil" (II.5) to be richly confessional, as well as very explicitly sexual? Or, as one final example, who would expect an essay "Of Cripples" (II.11) to either (a) discuss the witch trials or (b) discuss cripples principally in terms of whether the lame make better sexual partners?The surprises are not confined to the formal features of Montaigne's text, but also appear in the views he articulates. We would not expect an early modern Frenchman to write so sympathetically and even admiringly about the cannibals of the New World (I.31). Nor would we expect an early modern French Catholic to write in opposition to the witch trials. Montaigne does both—with incredible finesse. But despite the attractively progressive attitude seemingly manifested in these two stances, Montaigne's overall view is in fact far more conservative and quietistic than we might expect, were we judging based only on these few cases. And so he surprises us yet again: We are surprised to find him opposing the witch trials, and we are surprised a second time to find that his opposition does not signal any deeper tendency toward progressive or politically liberal views. In short, there is good reason [End Page 235] to see Montaigne's general stance as firmly traditional. While he sometimes expresses apparently progressive views, he does so in a way that has no stable basis in his overall conceptual scheme, as I will argue. Of course, merely observing this tension in Montaigne's work is nothing new. Hugo Friedrich, writing in 1949, and discussing II.11, claimed that "Montaigne bravely takes a position against the delusion of the masses and against clerical fanaticism."1 But in the same passage (and elsewhere) Friedrich shows himself to be well-aware that this apparent radicalism is balanced by Montaigne's conservatism.2 That tension—in a nutshell—encapsulates the debate.3 However, "Of Cripples" presents this tension in its most perplexing form, making a detailed analysis of II.11 our best hope of making progress on the debate.4To support these claims I propose to offer a careful textual analysis of Montaigne's discussion of the witch trials in "Of Cripples."5 After considering several philosophical interpretations of his key Augustinian principle, I will argue that Montaigne's critique of the witch trials is primarily driven by problems internal to the religious perspective, and so does not represent an attempt to circumscribe the authority of religion in the public sphere more generally.6 Such a position, then, is both traditional and quietistic—another of Montaigne's surprises for his readers. If this is correct, then one of the principal texts used for promoting a "liberal" Montaigne—namely, II.11—can be be reappropriated by the defenders of a "quietistic" Montaigne. Nonetheless, even on my reading, there remain some incompletely resolved tensions. That, perhaps, is no less than we should expect from history's only self-proclaimed "accidental philosopher."7IMontaigne opens "Of Cripples" by discussing the Gregorian reform of the calendar, which had been adopted in France in 1582. Yet as odd as this opening is, it serves to quickly introduce a familiar theme in the Essays: Even so basic a matter as the calendar is subject to "[s] o much uncertainty"—just like everything else—that "we are every day in doubt" about how to "keep a record of past events" (F, pp. 784–85). These thoughts are then quickly transformed into a skeptical reflection on human reason itself... (shrink)
