Examines interrelated topics in Medieval and Renaissance Latin literature: the status of women as writers, the status of women as rhetorical figures, and the status of women in society from the fifth to the early seventeenth century.

This book presents novel formalizations of three of the most important medieval logical theories: supposition, consequence and obligations. In an additional fourth part, an in-depth analysis of the concept of formalization is presented - a crucial concept in the current logical panorama, which as such receives surprisingly little attention.Although formalizations of medieval logical theories have been proposed earlier in the literature, the formalizations presented here are all based on innovative vantage points: supposition theories as algorithmic hermeneutics, theories of consequence (...) analyzed with tools borrowed from model-theory and two-dimensional semantics, and obligations as logical games. For this reason, this is perhaps the first time that these medieval logical theories are made fully accessible to the modern philosopher and logician who wishes to obtain a better grasp of them, but who has always been held back by the lack of appropriate ‘translations' into modern terms.Moreover, the book offers a reflection on the very nature of logic, a reflection that is prompted by the comparisons between medieval and modern logic, their similarities and dissimilarities. It is thus a contribution not only to the history of logic, but also to the philosophy of logic, the philosophy of language and semantics.The analysis of medieval logic is also relevant for the modern philosopher and logician in that, being the unifying methodology used across all disciplines at that time, logic really provided unity to science. It thus presents a unified model of scientific investigation, where logic plays the aggregating role. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Crossing Borders: Love between Women in Medieval French and Arabic LiteraturesCary Howie (bio)Sahar Amer, Crossing Borders: Love between Women in Medieval French and Arabic Literatures. Philadelphia: U of Pennsylvania P, 2008, xii + 254 pp.Sahar Amer’s Crossing Borders adds to the expanding bibliography on medieval sexualities by showing the resonances between certain female same-sex relationships in medieval French literature and analogous, though generally more explicit, relationships between (...) women in the medieval Arabic tradition. In the process, sexuality becomes a way of talking about the porous boundaries that constitute the field of Old French, and perhaps even Western, literature as such.Amer’s book couldn’t have arrived at a better time, as Sarkozy’s French government once again, in the name of French values, intervenes in the debates around religion and clothing in the public sphere, debates in which the old divides between France and its constitutive others—in this case, certain kinds of Islam and certain kinds of women— have once again come to the fore. By proposing that “medieval French writing is essentially a hybrid, cross-cultural project” (163), Amer contributes not just to the emerging sense of the Middle Ages’ postcoloniality (as articulated by Jeffrey Jerome Cohen and Sharon Kinoshita, among others) but also to the work being done by intellectual historians and cultural theorists such as Joan Scott and Diane Rubenstein on the fantastic investments that take place within and around French universalism (which could be said to inform the idea of the literary no less than the idea of the citizen).Crossing Borders begins with the notion of borders as “fluid spaces of cultural exchange, adaptation, and collaboration” (ix), and it is the emphasis on a more general sense of cultural exchange, more than the fact of borders per se, that will permeate the chapters that follow. (In fact, the border, like “the lesbian,” Amer’s polemical term of choice for the women she describes, may be important for her argument precisely insofar as it resists visibility, as it remains to some extent difficult to locate.) Amer’s reading of Old French texts, in dialogue with a handful of medieval Arabic narratives and erotic compilations, proceeds from an understanding of medieval culture in which there is “a continuity rather than a rupture between medieval and modern conceptions of alternative [End Page 156] sexualities” (9), and in which it is possible to argue for influences that are tough, if not impossible, to trace empirically. According to this logic, ideas and stories may have circulated “next to” more tangible material goods taken to and from the Arab Islamicate world (13), and French authors may have “culled some elements from Arabic material and wove[n] them into a literary fabric to suit their audience’s sensibilities” (163). This attentiveness to what “may have” happened (e.g., 44, 110) is one of the signature gestures of Amer’s critical poetics, which I am tempted to describe as an imaginative historicism, committed at once to the explanatory power of historical context and to what Amer will repeatedly call the “imagination of the audience” (e.g., 79).After an initial chapter outlining this “cross-cultural” poetics of contextualization and imaginative investment, chapter 2, “Crossing Linguistic Borders,” is dedicated to seven stanzas of a late twelfth-century poem, Étienne de Fougères’s Livre des manières, in which a long description is given of women who go “against Nature” by “join[ing] shield to shield without a lance” (32). Amer reads these military metaphors for female homoeroticism in light of Arabic sources including, for example, al-Jurjani’s eleventh-century Anthology of Metonymic Devices, in which one of the cited commonplaces observes, “They [lesbians] manifest a war in which there is no spear-thrusting” (36). Most provocatively, Amer argues for the Arabic provenance of two otherwise untranslatable words in Étienne’s text, “trutennes,” which she traces to an Arabic root meaning “the mons of the beloved” (40), and “eu,” which she interprets as an orgasmic onomatopoeia. From mons to moans, the “medieval French literary lesbian” is a condensation of forms and fantasies—and noises—that come from before and beyond medieval France. In fact, the... (shrink)

Medieval analyses of molecular propositions include many non-truthfunctional connectives in addition to the standard modern binary connectives (conjunction, disjunction, and conditional). Two types of non-truthfunctional molecular propositions considered by a number of 13th- and 14th-century authors are temporal and local propositions, which combine atomic propositions with `while' and `where'. Despite modern interest in the historical roots of temporal and tense logic, medieval analyses of `while' propositions are rarely discussed in modern literature, and analyses of `where' propositions are almost completely (...) overlooked. In this paper we introduce 13th- and 14th-century views on temporal and local propositions, and connect the medieval theories with modern temporal and spatial counterparts. (shrink)

The present chapter sketches the adoption of logic in late nineteenth and early twentieth century China. Addressing both conceptual and institutional aspects of this process, it contextualizes the raising interest in the discipline among Qing scholars and Republican intellectuals. Arranged largely chronologically, it delineates the successive periods in the reception of major works of and intellectual trends in the field. It introduces the most influential scholars promoting a public discourse on logic in the final years of the empire, but also (...) the ever more professional agents who participated in the ensuing establishment of a modern institutional framework for studies in logic like universities, departments of logic, academic societies, journals etc. While at the beginning, these people were mostly no trained logicians, progress in the establishment of academic logic in the 1930s provided the conditions for the formation of the first Chinese specialists in the field who were often internationally trained and soon to engage in cutting-edge research. In some contrast, academic discourse on logic well into the 1930s was dominated by exaggerated social and political expectations, not least due to the successive influence on intellectuals of inductionist scientism in the first decades of the twentieth century, of an inflated pragmatist notion of logic in the 1920s, and of an overly simplistic “antiformalist” notion of logic propagated by (vulgar-)Marxist historical dialecticians in the 1930s. The arrival of scientific logic also went in tandem with a renewed interest in studies in the traditional Buddhist “science of reasons” (yinming, hetuvidyā, “Buddhist logic”) and spurred the search for contributions to the field of logic in the record of inherited Chinese literature, a development which soon led to the common acceptance of the existence of genuinely Chinese traditions of logic. It is eventually a peculiarity of the Chinese reception of logic that since around 1920, less than two decades after the first modern translations of textbooks on traditional syllogistics, the visit of Bertrand Russell – one of the fathers of mathematical logic – fueled the spread of this new approach to logic which has eventually changed its face for good. Designed as a historical survey, this chapter is a general account on the major contributions to the field by Chinese scholars of the time and has to forego detailed discussions. (shrink)

Unione Accademica Nazionale, Corpus Philosophorum Medii Aevi, Subsidia XVIII. (...) Florence: SISMEL–Editioni del Galluzzo, 2010. Pp. xiii + 208. Cloth, €95.00.These two books are part of a series of volumes that will bring into final publication form one of the most significant scholarly achievements of the last half-century, Charles Lohr's inventory of the authors and manuscripts of Latin commentaries on the works of Aristotle up to 1650. The project began in the 1960s, and the initial results for the Middle Ages were published sequentially as articles in Traditio between 1967 and 1974, and the inventory for the period from 1500 to 1650 appeared in Studies in the Renaissance and Renaissance Quarterly between 1974 and 1981. The project was modeled along the lines of two great research tools achieved earlier in the twentieth century at Freiburg by Friedrich Stegmüller, namely his Repertorium Commentariorum in Sententias Petri Lombardi (1947) and his Repertorium Biblicum Medii Aevi (1940–). Now, through the Unione Accademica Nazionale and SISMEL, both of Lohr's inventories in revised and expanded form are being published as stand-alone volumes. The first two that appeared were Latin Aristotle Commentaries, II: Renaissance Authors (Subsidia VI, 1988), followed by Latin Aristotle Commentaries, III: Index initiorum—index finium (Subsidia X, 1995). The two volumes being reviewed here are the next two installments.The first of these, the Bibliography of Secondary Literature, is a much-expanded version of Lohr's Commentateurs d'Aristote au moyen-âge latin: Bibliographie de la littérature secondaire récente, Vestigia 2 (Fribourg-Paris, 1988). The intent of that volume was, as the title indicates, to provide a list of the scholarly literature on Aristotelian commentaries since the publication of the articles in Traditio, as well as some older literature that had not been included earlier in the entries for each author. The present version of this work is more than twice as large as the 1988 version, adding books and articles that were missed in the earlier bibliographies as well as publications since 1986 (the cutoff date for the earlier edition). Moreover, the Commentateurs d'Aristote provided a bibliography only for medieval commentaries, while the new Bibliography of Secondary Literature begins with a section covering literature about translations of the works of Aristotle and their Wirkungsgeschichte, then [End Page 141] the section for the literature on medieval authors, and finally the section for bibliography on Renaissance authors.The organization of the bibliography for authors that have generated extensive literature is more complex than for the others. The longer bibliographies are divided into works concerned with biographical information and manuscripts; general accounts; and, depending on the contributions of a specific author, sections on logic, metaphysics, natural philosophy, and practical philosophy. Within each of these sections the literature is arranged by date of publication, moving from the older to the most recent (limited, of course, by the cutoff date at which this volume was prepared for publication, apparently around 2003). The principle of inclusion was broad, citing works that relate tangentially to the subject areas of Aristotelian philosophy mentioned. And although bibliographies of this kind should be made available on the Internet, where they can be continually expanded and updated, it is useful and pleasurable to have such a volume on the shelf at one's fingertips, particularly for those of us still attuned to a print culture.The other volume, Latin Aristotle Commentaries, I.2: M–Z, published in 2010, is the second half of the revised edition of medieval authors and their commentaries on Aristotle's works. Some bibliography is included here in the individual entries, but only what relates to the manuscripts. The entries consist of a brief biographical sketch of the author, followed by the list of commentaries (both extant and lost), each one with an... (shrink)

The doctrine of the Trinity is central to mainstream Christianity. But insofar as it posits “three persons” (Father, Son and Holy Spirit), who are “one God,” it appears as inconsistent as the claim that 1+1+1=1. -/- Much of the literature on “The Logical Problem of the Trinity,” as this has been called, attacks or defends Trinitarianism with little regard to the fourth century theological controversies and the late Hellenistic and early Medieval philosophical background in which it took shape. I (...) argue that this methodol- ogy, which I call “the Puzzle Approach,” produces obviously invalid arguments, and it is unclear how to repair it without collapsing into my preferred method- ology, “the Historical Approach,” which sees history as essential to the debate. I also discuss “mysterianism,” arguing that, successful or not, it has a different goal from the other approaches. I further argue that any solution from the His- torical Approach satisfies the concerns of the Puzzle Approach and mysterianism anyway. -/- I then examine the solution to the Logical Problem of the Trinity found in St. Gregory of Nyssa’s writings, both due to his place in the history of the doctrine, and his clarity in explicating what I call “the metaphysics of synergy.” I recast his solution in standard predicate logic and provide a formal proof of its consistency. I end by considering the possibilities for attacking the broader philosophical context of his defense and conclude that the prospects for doing so are dim. In any case, if there should turn out to be any problem with the doctrine of the Trinity at all, it will not be one of mere logical inconsistency in saying that “These Three are One.”. (shrink)

This splendid little volume is the edited version of a series of lectures delivered at the Catholic University of America in March, 1981, by a noted authority on both Stoicism and the history of medieval philosophy. Its aim is not to track down all of the Stoic elements imbedded in the philosophic and theological literature of the Middle Ages--a vast enterprise to which scholars have yet to turn their attention--but to offer a preliminary survey that could conceivably "serve as (...) a stimulus for further research". The assembled material, and there is much of it, has been conveniently organized under the following chapter headings: "The Challenge of Materialism", "Ethical Perspectives", and "Fatalism and Freedom". In the interest of time and space, other important considerations, such as those pertaining to Stoic cognitive theory and Stoic logic, have been mostly left aside. Chapter One, which constitutes an introduction to the work as a whole, is devoted to an examination of the various sources to which the medievals were indebted for their knowledge of Stoic philosophy. The achievement is an impressive one by any standard and the reader can only admire the ease with which the author, who is so obviously in command of his subject, is able to move from one topic to another or from one author to another.

The volume provides an overview of the origins of early medieval aristocratic literature. Although there are regional, linguistic and formal differences, one can observe a number of similarities. Oral literature disseminates a range of themes that are shared by narratives in most parts of the continent. The authors address these similarities in Roman, Nordic, Anglo-Saxon and Germanic literature and use different methodologies to explain them.

Purpose. The purpose of the study is to show the connection of romanticism with the anthropological doctrine that goes back to Hegelianism and Kantianism, and at the same time – with the concepts of the future, structuralism and postmodernism. Theoretical basis. The man is a central figure of the Romantic literary, therefore it makes sense to single out romantic human anthropological doctrine and the image of man associated with a specific historical and cultural era called the "epoch of romanticism"; to (...) show that many romantic philosophical positions remained relevant to the basic foundations of contemporary anthropological research and coincide with it in analytical and critical thinking about a man, a person, his historical and evolutionary fate. Originality. The romantic worldview determined the specifics of anthropological discourse, both logical and illogical, remaining symbols and attaching, as for example, a real historical anecdote, a popular history, a philosophical thought, a myth, a famous literary episode and the arts multiplied by creative inspiration and imagination. This tendency determined the fragmentation of thinking and the scientific image of man as a dual being, nevertheless, presented and described in all the variety of relations with the world and with himself, that allows us to call this area of thought "the romantic human science". Conclusions. Structural analysis of numerous romantic texts allows us to draw the following conclusion: with mythopoetic imagery and anthropological thought about a man, romantic writers introduced the reader to any wisdom, to philosophical understanding of their human essence, to past and modern teachings, in a way processed antique, medieval and enlightening views, in which an important place was given to reflections on the place of man in nature, society, and history. Correlating the well-known statements about a person as a descendant of the "old Adam", "person", "personality", "soul", with the modern idea of historical and social development, about the evolution of the consciousness of a person who revealed himself as an individual in modern times, with scientific and aesthetic views, the writers of the first half of the XIX century gave romantic thought anthropological meaning and, in fact, laid the foundations of historical, social, psychological, cultural and psychoanalytic anthropology.

This chapter contains sections titled: A Timeline of Medieval Logicians A Guide to the Literature.

This series of interpretations of selected classics examines premodern Japanese literature from the perspective of conflictual ideologies. Professor Marra's analysis of such works as the Ise Monogatari, the Hojoki, and Tsurezuregusa highlights the existence of discontent in the authors of the so-called high tradition and explains the means these authors used to express their social dissatisfaction in literary texts. His aim is to recover the validity of the historicist approach in literary studies by focusing on the importance of the (...) context in the formation of the text. The text is seen as a product of ideological manipulation on the part of those who, by reading, writing or editing, appropriate it according to specific and private concerns. Professor Marra displays both sensitivity to the texts and a comprehensive grasp of Japanese and Western scholarship in making his argument that aesthetics and politics in premodern Japanese literature are mutually defining.

Our current society seems to require a sharp separation between what can be tolerated in public and what must remain hidden. There is explicit and implicit censorship of both the subject of death and of the crying and suffering of surviving relatives and friends. Medieval literature and literary studies, however, show how the experience of dying and its appropriate manifestations of grief seemed to be more integrated into everyday life, as opposed to the apparent “disintegration” of nowadays. It is (...) possible to begin to detect this evolution already in medieval Hispanic literature itself, from an apparently more public, visible and integrated death in 13th-century Hispanic literature to a more private, concealed and disintegrated death in 15th-century Hispanic literature. This process will continue its journey to the present society of eternal springs and summers from which we have eradicated autumns and winters, seasons as necessary for the cycle of life – for personal, psychological and social balance – as the first two. Keywords: death; mourning; crying; medieval literature. Resumen Nuestra sociedad actual parece presentar una tajante separación entre lo que puede ser tolerado en público y lo que debe permanecer oculto. Hay una censura explícita e implícita tanto del tema de la muerte como del llanto y el sufrimiento de los familiares y amigos supervivientes. Sin embargo, la literatura medieval y los estudios literarios sobre la misma muestran cómo la experiencia del morir y sus apropiadas manifestaciones de dolor parecían estar más integradas en la vida cotidiana en contraposición a la aparente “desintegración” actual. Es posible comenzar a detectar esta evolución ya en la propia literatura hispánica medieval, desde una muerte aparentemente más pública, visible e integrada en la literatura hispánica del siglo XIII hasta una muerte más privada, oculta y desintegrada en la literatura hispánica del siglo XV. Este proceso continuará su recorrido hasta una sociedad actual de eternas primaveras y veranos de la que hemos erradicado los otoños e inviernos, estaciones tan necesarias para el ciclo de la vida —para el equilibrio personal, psicológico y social— como las dos primeras. Palabras clave: muerte; duelo; llanto; literatura medieval. (shrink)

The focus on the Logica Nova in the research on 11th and 12th century Quaestio-literature is misleading. It seems to derive from a particular view of the Logica Vetus, which takes Boethius seriously only as a translator and perhaps a commentator of Aristotle. The puzzlement dissappears when Boethius is taken seriously as a logician and dialectician in his own right. Two Boethian works are of particular importance for early medieval as well as for Boethian dialectic, namely the commentary on (...) Cicero's Topica and the De Differentiis Topicis. While all great historians and medieval philosophy acknowledge the early presence and importance of these works, the extent of their influence on the development of the Quaestio has yet to be appreciated. The first section develops the problem by giving an outline of the important features of Bazàn's account of the Quaestio and its place between Lectio and Disputatio. The second section studies Boethius account of dialectic, with particular consideration of teh commentary on Cicero's Topica and the De Differentiis Topicis. The third section argues that Bazàn's and Grabmann's assumption that the 'old logic' did not provide the necessary means for the development of the Quaestio is unjustified. The fourth and final section offers some remarks on the relation of Abelard's Sic et Non to the method of the Quaestio. (shrink)

Name der Zeitschrift: Der Islam Jahrgang: 94 Heft: 1 Seiten: 304-308.

Exploring and understanding how medieval Christians perceived and constructed the figure of the Prophet Muhammad is of capital relevance in the complex history of Christian-Muslim relations. Medieval authors writing in Latin from the 8th to the 14th centuries elaborated three main images of the Prophet: the pseudo-historical, the legendary, and the eschatological one. This volume focuses on the first image and consists of texts that aim to reveal the truth about Islam. They have been taken from critical editions, where available, (...) otherwise they have been critically transcribed from manuscripts and early printed books. They are organized chronologically in 55 entries: each of them provides information on the author and the work, date and place of composition, an introduction to the passage reported, and an updated bibliography listing editions, translations and studies.

Focusing on the sixteenth-century Oriya Lakshmi Purana by Balaram Das, this essay shows how distinctly “modern” values are being explored and elaborated in this religious poem. Das’s narrative develops the notion of a self-critical individuality that is distinct from—rather than merely embedded in—the dominant social structure and its patriarchal and caste-based value system. The LP provides a feminist and anticaste critique of patriarchal behavior and defends the value of the work done by women and others who are socially marginalized. This (...) literary-critical analysis is a contribution to contemporary scholarship on “alternative” or “precolonial” modernities, especially in the Indian context. (shrink)

In this paper I examine Avicenna’s conception of the consequence relation. I will consider in particular his categorical and hypothetical logics. I will first analyse his definition of the implication and will show that this relation is not a consequence relation in his frame. Unlike the medieval logicians, he does not distinguish explicitly between material and formal consequences. The arguments discussed in al-Qiyās, where the conclusion is true only in some matters, and would seem close to a material consequence for (...) that reason, are rejected explicitly as not syllogistic. He also rejects the ‘enthymemes’ unless they are complemented by their missing premise and the superfluous premises which, according to him, should promptly be ruled out. It seems then that the consequence relation in his theory is formal. It can be characterized as being ‘productivity in all matters’ or ‘necessary truth preserving’. It is illustrated by some single premise arguments, and above all by all kinds of syllogisms which, in his theory, are more numerous and various than in Aristotle’s one. The syllogism may contain two or more premises, including disjunctive ones. When it is hypothetical, it may lead to several conclusions. The premises may be in conflict, but then, the conclusion is false. He thus rejects the principle according to which ‘anything follows from a contradiction’. But, unlike what some scholars say, he does not admit any connexive principle. In the compound syllogisms, the conclusion follows by steps, each step taking two premises at once. (shrink)

Inspired by an interesting quotation from the literature, we propose four modalities, called ‘sane belief’, ‘insane belief’, ‘reliable belief’ and ‘unreliable belief’, and introduce logics with each operator as the modal primitive. We show that the four modalities constitute a square of opposition, which indicates some interesting relationships among them. We compare the relative expressivity of these logics and other related logics, including a logic of false beliefs from the literature. The four main logics are all less expressive (...) than the standard modal logic over various model classes, and the logics of sane and insane beliefs are, respectively, equally expressive as the logics of unreliable and reliable beliefs on any class of models. The logics of reliable and unreliable beliefs are then combined into a bimodal logic, which turns out to be equally expressive as the standard modal logic. Despite this, we cannot obtain a complete axiomatization of the minimal bimodal logic, by simply translating the axioms and rules of the minimal modal logic $\textbf{K}$ into the bimodal language. We then introduce a schematic modality which unifies reliable and unreliable beliefs and axiomatize it over the class of all frames and also the class of serial frames. This line of research is finally extended to unify sane and insane beliefs and some axiomatizations are given. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.2 (2003) 168-172 [Access article in PDF] Logic and the Art of Memory: The Quest for a Universal Language. Paolo Rossi. Trans. Stephen Clucas. Chicago: University of Chicago Press, 2000. Pp. xxviii + 333. $32.00 cloth. Of the traditional five canons of rhetoric—inventio, dispositio, elocutio, memoria, and actio—the most circuitous and fascinating history belongs to memoria. From its propulsion of Homeric lore to its grounding of (...) rhetorical invention to its exile under print culture to its recent revival in public memory studies, the promiscuous and perplexing history of memory in the West may be one of the least appreciated, and perhaps least understood, elements of rhetorical and intellectual history. The publication in 1966 of Frances Yates's highly praised The Art of Memory drew the attention of contemporary scholars to the importance of mnemotechnics to the culture of late medieval and early modern Europe. 1 Yates persuasively argued that the art of memory is an integral element of European intellectual history, one that can enrich our understanding of everything from Dominican theology to Shakespearian theater. However, six years earlier, in 1960, the Italian intellectual historian Paolo Rossi published in Italian an important precursor to Yates's work entitled Clavis Universalis: Arti Della Memoria e Logica Combinatoria da Lullo a Leibniz. The book traces the encyclopaedic and mnemotechnical traditions from Aristotle through Cicero and Raymond Lull and into the early-modern period, arguing that the art of memory provides an important antecedent to the advent of method in seventeenth-century philosophy, especially in the works of Bacon, Descartes, and Leibniz. Yates, in her preface to The Art of Memory, acknowledges her debt to Rossi's work, and now this work has been made available in English translation. Stephen Clucas's translation, under the title Logic and the Art of Memory, will no doubt stimulate and supplement research into the mnemotechnical tradition in the English-speaking world, and perhaps lead us to reconsider the relationship between philosophy and rhetoric.Rossi argues that the neglect of the mnemotechnical tradition in its Ciceronian and Lullian strands has distorted our understanding of the "new" science and philosophy of the seventeenth-century, which is often interpreted as constituting, in a Kuhnian sense, a drastic paradigm shift from a [End Page 168] Renaissance worldview that still retained occult elements. Rossi places the work of Bacon, Descartes, and Leibniz within the historical strand of the logico-encyclopaedic and mnemotechnical traditions, suggesting that these figures culminate late medieval and early modern intellectual and cultural ambitions as much as they give rise to new ones. Rossi makes his argument by providing a history of mnemotechnics from Aristotle into the fifteenth century in chapter one; by examining the fascination with encyclopaedism, combinatoria, and memory in the sixteenth century in chapters two and three; by investigating the role of artificial memory in the works of key intellectual figures in the late sixteenth and seventeenth centuries in chapters four through six; and by tracing the impulse toward universal knowledge and its connection to mnemotechnics among seventeenth-century Cartesians, Baconians, and in the work of Leibniz, in chapters seven and eight.Chapter one, after showing the pervasiveness of Renaissance mnemotechnical literature, surveys its classical and medieval antecedents in philosophy and rhetoric. Rossi argues that Aristotle's De memoria et reminiscentia, Cicero's De oratore, Quintilian's De institutione oratoria, the Rhetorica ad Herennium, and the works of Albertus Magnus and Thomas Aquinas were each important to the mnemotechnical tradition into the seventeenth century. Fourteenth- and fifteenth-century treatises on the ars memorativa and the ars predicandi, drawing on these classical and medieval theories, emphasize the importance of memory places (loci), images (imagines), and order or arrangement (dispositio) in mnemotechnics. Additionally, they intimately link the memory to the imagination, stressing the importance of exciting and stimulating the imagination in memorization. The Italian Pietro da Ravenna, for example, attributed the might of his memory to, in his own words, turning "the images of the most beautiful virgins into memory places" (22). Such imaginative mnemonic techniques were considered to... (shrink)
