In its formlessness and potentiality, prime matter is a problematic entity of medieval metaphysics and its ontological limitations drastically affect human possibility of conceiving it. In this article, I analyse three influential strategies elaborated to justify an epistemic access to prime matter. They are incidental perception, negative abstraction, and analogy. Through a systematic and historical analysis of these procedures, the article shows the richness of interpretations and theoretical stakes implied by the conundrum of how prime matter can be known by (...) human beings. In particular, the reasons behind the later medieval acceptance of analogy as the main way to unveil prime matter become clearer by pointing out the correlation between the ontological and epistemological levels of the medieval examination of prime matter.

This article analyses the peculiarities of Dominicus Gundissalinus’s reading and use of Avicenna’s writings in his original works. Gundissalinus (1120ca – post 1190) is the Latin translator of Avicenna’s De anima and Liber de philosophia prima, but also an original philosopher whose writings are precious witnesses of the very first reception of Avicennian philosophy in the Latin West. The article points out the structural bond with the Persian philosopher upon which Gundissalinus grounds his own speculation. This contribution stresses, in particular, (...) the important role played by Avicenna’s psychology, epistemology, and metaphysics in order to provide Gundissalinus with a different set of answers to at least two main questions. On the one hand, the problem of creatural existence and cosmological causation, concerning which Gundissalinus tends to doctrinally merge Avicenna with Ibn Gabirol. On the other hand, Avicenna’s influence is crucial for Gundissalinus’s attempt at elaborating a new system of knowledge, which was supposed to be able to include the new sciences made available by the translation movement, but that also needed to be internally organised through firm epistemological principles. Beside his crucial contribution as translator, Gundissalinus’s first philosophical encounter with the Avicenna paved the road for the subsequent reception of the Persian philosopher’s works, opening a hermeneutical perspective which would be pivotal for the thirteenth-century discussions on soul, knowledge, and being.

In this essay, the author examines the problem of the composition of spiritual substances in Thierry of Chartres and Gundissalinus. While Thierry is reticent to admit a hylomorphism in spiritual creatures, Gundissalinus develops Thierry’s thought on the matter through al-Ghazālī’s and Ibn Daud’s treatment of the composition in spiritual substances. Gundissalinus concludes that spiritual creatures are composed of matter and form, a conclusion that would be unacceptable to his main philosophical authorities.

Scholastic hylomorphism conceives prime matter and substantial form as metaphysical parts of every physical substance. During the early modern period, both hylomorphic constituents faced significant criticism as scientists and philosophers sought to replace Aristotelianism with physical explanations for the workings of the universe. This paper focuses specifically on prime matter and delves into the arguments put forth by four 16th-century scholastic philosophers – Toledo, Fonseca, Góis, and Suárez – in their attempts to establish the existence of prime matter. Firstly, I (...) analyse a set of arguments rooted in substantial change, which emphasize the crucial role of a persistent, common substrate in the processes of generation and corruption. Secondly, I explore a set of ex-nihilo arguments and, thirdly, I examine a series of demonstrations based on the interplay between accidental and substantial change. Although these three sets of arguments converge on the necessity of a common substrate for substantial change to occur, they fall short of demonstrating that this substrate is both prime and shared by all natural entities. Fourthly, I turn to a set of arguments centred on the impossibility of infinite regress, designed to complement those related to natural change, and I assess additional arguments that do not primarily focus on substantial change. Lastly, I draw my conclusions on these argumentative strategies to demonstrate the existence of prime matter. (shrink)

Cette étude présente les principaux témoignages en notre possession, ainsi que les hypothèses émises par les historiens, sur la biographie de Dominique Gundisalvi, traducteur et philosophe actif à Tolède dans la seconde moitié du xii e siècle.

L’article pointe des détails importants concernant le séjour de Gundisalvi à Ségovie, tout en essayant d’expliquer les raisons de son installation (...) à Tolède en 1162. (shrink)

RésuméCet article envisage la stratégie d'altération textuelle réalisée par Dominique Gundisalvi dans ses œuvres originales. Un des exemples les plus significatifs de cette stratégie peut être reconnu dans la longue citation de Metaphysica I, 6–7 d'Ibn Sīnā dans le traité cosmologique de Gundisalvi, le De processione mundi, où le philosophe espagnol modifie différemment le texte qu'il a traduit quelques années auparavant. Après une brève présentation du double rôle de Gundisalvi comme traducteur et philosophe, on analyse la doctrine de l’être nécessaire (...) et de l’être possible d'Ibn Sīnā, et les cinq démonstrations de l'unicité sans relation de l’être nécessaire offertes par Ibn Sīnā. Ces arguments sont cités directement par Gundisalvi: l'auteur cependant modifie le texte en plusieurs passages qui sont examinés à travers l'analyse des cas les plus exemplaires. Les résultats de cette enquête nous suggèrent que Gundisalvi suit une véritable stratégie d'altération, ayant en vue deux finalités principales: la clarification de la ligne de raisonnement d'Ibn Sīnā et l'assimilation de ses théories dans le système doctrinal de Gundisalvi. En appendice à cet article on présente en entier le texte des deux variantes de Metaphysica I, 6–7. (shrink)

This study deals with Dominicus Gundissalinus’s discussion on metaphysics as philosophical discipline. Gundissalinus’s translation and re-elaboration of al-Fārābī’s Iḥṣā’ al-ʿulūm furnish him, in the De scientiis, a specific and detailed procedure for metaphysical analysis articulated in two different stages, an ascending and a descending one. This very same procedure is presented by Gundissalinus also in his De divisione philosophiae, where the increased number of sources –in particular, Avicenna– does not prevent Gundissalinus to quote the entire passage on the methods of (...) metaphysical science from the Iḥṣā’ al-ʿulūm, with some slight changes in his Latin translation. The analytical procedure herein proposed becomes an effective ‘metaphysical programme’ with regards to Gundissalinus’s onto-cosmological writing, the De processione mundi. The comparative analysis of this treatise with the procedure received by al-Fārābī shows Gundissalinus’s effort to follow and apply this metaphysical programme to his own reflection, in a whole different context from al-Fārābī’s and presenting doctrines quite opposed to the theoretical ground on which al-Fārābī’s epistemology is based, like ibn Gabirol’s universal hylomorphism. Nevertheless, thanks to the application of the ‘metaphysical programme’, one can effectively claim that Gundissalinus’s metaphysics is, at least in the author’s intentions, a well-defined metaphysical system. In appendix to this article the three Latin versions of al-Fārābī’s discussion on metaphysics are reported, e.g., Gundissalinus’s quotations in De scientiis and De divisione philosophiae, and Gerard of Cremona’s translation in his De scientiis.

With his original reflection—deeply influenced by many important Arabic thinkers—Gundissalinus wanted to renovate the Latin debate concerning crucial aspects of the philosophical tradition. Among the innovative doctrines he elaborated, one appears to be particularly problematic, for it touches a very delicate point of Christian theology: the divine creation of the human soul, and thus, the most intimate bond connecting the human being and his Creator. Notwithstanding the relevance of this point, Gundissalinus ascribed the creation of the human soul to the (...) angels rather than God. He also stated that the angels create the souls from prime matter, and through a kind of causality which cannot be operated by God. What are the sources of this unusual and perilous doctrine? And what are the reasons which led Gundissalinus to hold such a problematic position? This article thoroughly examines the theoretical development and sources of Gundissalinus’s position, focusing on the correlations between this doctrine, the overall cosmological descriptions expounded by Gundissalinus in his original works, and the main sources upon which this unlikely doctrine is grounded: Avicenna and Ibn Gabirol.

Cette contribution s’intéresse à la position problématique des arts mécaniques dans les systèmes médiévaux du savoir. Remplaçant la position secondaire assignée aux arts mécaniques du début du Moyen Âge, les solutions proposées par Hugues de Saint-Victor et Gundissalinus eurent une influence forte durant le XIIIe s. Alors que l’intégration des arts mécaniques dans le système de connaissance de Saint-Victor trahit leurs positions encore accessoires vis-à-vis de la considération des arts libéraux, Gundissalinus propose deux principales nouveautés. D’un côté il place les (...) arts mécaniques aux côtés de l’alchimie et des arts de prédiction et de magie. D’un autre côté cependant, utilisant la théorie avancée par Avicenne, il subordonne ces « sciences naturelles » à la philosophie naturelle elle-même, établissant ainsi une architecture du savoir plus vaste et plus organisée hiérarchiquement. Notre contribution examine les implications découlant de ces développements ainsi que leur réception à Paris durant le XIIIe s., soulignant la pertinence des solutions proposées par Gundissalinus dans les discussions qui ont suivi, concernant la structure de la connaissance humaine.

La contribución de Domingo Gundisalvo a la historia de la filosofía medieval ha sido de fundamental importancia especialmente por su originalidad y sincretismo. Sin embargo, la recepción explícita de las obras de Gundisalvo en el siglo XIII ha sido explorada sólo parcialmente. Este artículo discute el problema desde un punto de vista metodológico a través del examen de un caso particular: la influencia de las obras de Gundisalvo en la Summa Halensis. Después de haber presentado los problemas principales de un (...) análisis del impacto de Gundisalvo en el siglo XIII, el artículo discute algunos ejemplos de la influencia explicita en Roger Bacon y Thomas de York. La ultima parte de la contribución examina el uso del De unitate et uno de Gundisalvo por parte de los autores de la Summa Halensis y un posible ejemplo de influencia implícita de otros textos gundisalvianos en esta obra.

Few figures of the Middle Ages command the attention of so many modern disciplines as Robert Grosseteste (c. 1170-1253). Theology, Philosophy, History, and Science are all areas which his life and thought continue to have significance and to inspire re-interpretation. Accompanied by a series of original commentaries, this new edition of Grosseteste's work, with English translation, draws together the perspectives of modern scientists and medieval specialists. Volume I of a six volume series, Knowing and Speaking presents two of the earliest (...) of Grosseteste's works, the treatises On the Liberal Arts and On the Generation of Sounds. These are accompanied by a significant Middle English treatise on the Seven Liberal Arts whose anonymous fifteenth-century author translated and excerpted passages from Grosseteste's treatises in a re-imagining of their structure and function.0Each work is treated separately within the volume, which is constructed in three parts. On the Liberal Arts sets Grosseteste's thoughts on the arts subjects and emphasises moral concerns about the purpose of learning. On the Generation of Sounds builds on the theories and statements of On the Liberal Arts in connection to the production of sound, elaborating the earlier position, relating the generation of sounds to human vocal and speech production.

The Philosophy and Science of Roger Bacon offers new insights and research perspectives on one of the most intriguing characters of the Middle Ages, Roger Bacon. At the intersections between science and philosophy, the volume analyses central aspects of Bacon's reflections on how nature and society can be perfected. The volume dives into the intertwining of Bacon's philosophical stances on nature, substantial change, and hylomorphism with his scientific discussion of music, alchemy, and medicine. The Philosophy and Science of Roger Bacon (...) also investigates Bacon's projects of education reform and his epistemological and theological ground maintaining that humans and God are bound by wisdom, and therefore science. Finally, the volume examines how Bacon's doctrines are related to a wider historical context, particularly in consideration of Peter John Olivi, John Pecham, Peter of Ireland, and Robert Grosseteste. The Philosophy and Science of Roger Bacon is a crucial tool for scholars and students working in the history of philosophy and science and also for a broader audience interested in Roger Bacon and his long-lasting contribution to the history of ideas.

Dominicus Gundissalinus was both a philosopher and a translator; he was active in the unique context of Toledo in the second half of the twelfth century, a cultural melting pot of Muslims, Jews, and Christians. While he was philosophically trained in the Latin tradition, he found answers to the philosophical problems originating from that Latin training in the Arabic tradition of authors and texts which he himself translated. Outside the boundaries of specialised knowledge and research, this intriguing thinker is unknown; (...) this study contributes to the re-discovery of Gundissalinus, with a philosophical and historical analysis of his metaphysical reflection in order to display its profound originality and pioneering contribution to the course of medieval philosophy.

The volume gathers eleven studies on the intellectual exchanges during the Middle Ages among the three cultures which existed side by side in the same geographical area, i.e. the vast space from the British Isles to the Sahara Desert, and from the Douro Valley to the Hindu Kush. These three cultures – who may not be reduced to their confession or ethnicity – are historically related to each other in many respects, both material (trade, wars, marriages) and immaterial (the interdependence (...) among their religious narratives and their philosophical speculations). The studies herein presented focus on some peculiar examples of the transcultural interactions among exponents of the Arabic, Hebrew and Latin philosophical and theological traditions. While we do not want to downplay the fundamental role of the religious contexts, our focus on the linguistic denominations of these cultures aims at drawing attention to the conceptual medium, or rather media, which underlined and shaped the interactions and interplays among these traditions – interplays that were characterized by the contact of these three languages being used by people of different religious beliefs in their quest for knowledge: Spanish Jews writing in Arabic, Jews collaborating in the translation of Arabic texts into Latin through the vernacular, Western Muslims whose writings were read mainly by Jews and Christians in Hebrew and Latin.

Gundisalvo desempeñó su papel principal como filósofo, y como tal, fue el primero en acoger críticamente las doctrinas avicenianas, farabianas, gabirolianas y aristotélicas. En este sentido, Gundisalvo nos proporciona un panorama donde el platonismo timaico típico de la Escuela de Chartres y de Hermann de Carintia estaba en crisis y que, en varias décadas, llegó a ser superado por la revolución aristotélica del siglo XIII. En sus escritos, Gundisalvo parece quedarse entre las dos orillas de este caudal especulativo, acogiendo el (...) aristotelismo neoplatónico árabe y rechazando fundamentos doctrinales timaicos, sin renegar de su formación platónica y boeciana. Por consiguiente, además del explícito valor de sus traducciones y de aquellos textos que tuvieron una gran difusión y recepción, como el De divisione o el De unitate, resulta evidente el valor implícito de la figura de Domingo Gundisalvo como filósofo un contexto cultural irrepetible como lo fue Toledo en el siglo XII.

The volume collects twenty-eight original essays by colleagues and friends of Michela Pereira offered on the occasion of her seventieth birthday. As a pioneer of the re-evaluation of fundamental areas of the Western philosophical and scientific tradition, starting with alchemy, Michela Pereira has dedicated important studies to Hildegard of Bingen, Roger Bacon, Ramon Llull, in addition to being one of the most authoritative interpreters of the feminist movement in the modern world. «Seeing in the shadow», the title of this volume, (...) recalls a suggestive image coined by Hildegard to establish a connection between the work of creation, human nature and prophetic knowledge, three contexts around which the interests of Michela Pereira turn. The essays of the volume interpret these topics in many thought-provoking ways. Covering a wide temporal arc, from late Antiquity to Early Modern Times, and ranging from alchemy and medicine to spirituality, prophecy and myth, from the body-soul relation to performative arts, such as theatre and music, they also include brief editions of unedited medieval texts and an updated bibliography of Michela Pereira’s publications.
