The first part of this essay treats Eriugena's concept of theophany. Because nature is to be understood as theophany, every visible and invisible creature is a divina apparitio. The second part explains that appearing nature is the metaphor of a creative principle. Metaphor is the inner structure of nature as a process of appearance and the inner structure of our speaking about nature as metaphor. The third part infers that the recognition of nature as metaphor is based upon the (...) thinking of appearance. To understand the cause through which every phenomenon of nature becomes a metaphor means to understand the dialectic of appearing nature: it means to understand nature as apparitio non apparentis. The fourth part concludes that in moments of beauty we recognize the nature of metaphor and nature as metaphor. Beauty is the givenness of what we think as the vivid cause of appearing nature. Its cause - and beauty fundamentally - is the self-consciousness of nature as appearance. Both nature as well as beauty are nonmetaphorical metaphors of themselves. (shrink)

This article charters the history and work of the Society for the Promotion of Eriugenian Studies, which celebrated its 50-year jubileum in 2020. After a brief introduction to the thought of John Scottus Eriugena, with emphasis on his primary text, Periphyseon, written between 864 and 866 and condemned as heretical in 1050, 1059, 1210 and finally in 1225, the development of SPES over the past five decades is surveyed in detail and connected to an outstanding work published in the (...) Brill’s Companions to the Christian Tradition series in Leiden, under the editorship of Adrian Guiu. The article is descriptive and analytical in its presentation of the relevant history of ideas and synthetical in its attempt to coherently integrate the most recent secondary texts on the relevant philosophical themes in Eriugena research.Contribution: The article contributes to the Society for the Promotion of Eriugenian Studies’ 50-year jubileum by summarising its conference outputs over the past five decades in an extensive overview as well as connecting its work to A Companion to John Scottus Eriugena, thereby furthering the society’s efforts and specialist research outputs to a broader, non-specialised readership.

This article reconsiders the historical–philosophical significance of the monk and abbot of Corbie Abbey (est. 657), Paschasius Radbertus (c. 790–860). Radbert is contextualised within the cultural and academic setting of the Carolingian period of the eighth and ninth centuries while taking into account the diverse scholarly accomplishments of his contemporaries such as Alcuin of York (c. 740–804), Rabanus Maurus (c. 780–856), Walafrid Strabo (c. 809–849) and John Scottus Eriugena (815–877). The characteristic absence of contributions regarding Radbert in otherwise comprehensive (...) introductions and editorial works in medieval philosophy is subsequently surveyed. It is shown that only a few introductory works of note contain references to Radbert, while the current specialised research is also relatively limited. Reconsidering depictions of Radbert in several older commentaries, notably Martin Grabmann’s (1875–1949) Die Geschichte der Scholastischen Methode I ( 1957 ), it is suggested that Radbert’s philosophical importance could be traced to Vorscholastik or the earliest development of scholasticism, as presented in his extensive commentary Expositio in Matheo Libri XII – without diminishing the ecclesiastical weight of his dispute with Ratramnus (d.c. 868) regarding their interpretation of the Eucharist in their similarly titled but disparate treatises De corpore et sanguine Domini, for which Radbert is generally better known and accordingly reflected in studies of early medieval intellectual history. Contribution: This article contributes to scholarship in early medieval philosophy by reassessing the philosophical influence of Paschasius Radbertus, based on the most recent specialised analyses and older modern receptions of his texts De corpore et sanguine Domini and Expositio in Matheo Libri XII.

Johannes Scottus Eriugena ragt als ein der Antike kongenialer Denker mit seinem originellen theologisch-philosophischen Entwurf von Gott und Welt weit über seine Zeitgenossen des 9. Jahrhunderts hinaus. Die vorliegende Untersuchung arbeitet die zentrale Bedeutung des freien Willens und einer optimistischen Sicht der Schöpfung für das Gesamtsystem heraus und zeigt inhaltliche Parallelen zwischen dem Werk des frühmittelalterlichen Autors und seiner irisch-keltischen Herkunft auf.

In this article I wish to re-examine the vexed issue of the possibility of idealism in ancient and medieval philosophy with particular reference to the case of Johannes Scottus Eriugena (c. 800–c. 877), the Irish Neoplatonic Christian philosopher. Both Bernard Williams and Myles Burnyeat have argued that idealism never emerged (and for Burnyeat, could not have emerged) as a genuine philosophical position in antiquity, a claim that has had wide currency in recent years, and now constitutes something of (...) an orthodoxy.1. Myles Burnyeat, “Idealism and Greek Philosophy: What Descartes Saw and Berkeley Missed,” Philosophical Review 91 (1982): 3–40, repr. in Godfrey Vesey, ed., Idealism—Past and Present (Cambridge: Cambridge U.P., 1982), pp. 19–50. Hereafter this essay will be cited in the version printed in Vesey, ed. Richard Sorabji (instancing Gregory of Nyssa) and Werner Beierwaltes (citing Proclus and Eriugena), and Eyjólfur Kjalar Emilsson (discussing Plotinus), on the other hand, have all argued that idealism is to be found in the Neoplatonic tradition, a tradition neglected by Burnyeat.Richard Sorabji, “Gregory of Nyssa: The Origins of Idealism,” in Time, Creation and Continuum. Theories in Antiquity and the Early Middle Ages (London: Duckworth, 1983), pp. 287–96; Werner Beierwaltes, Denken des Einen.

Eine kurze, unsystematische Nachlese,” in Eriugena. Grundzüge seines Denkens (Frankfurt: Klostermann, 1994), pp. 313–330. Eyjólfur Kjalar Emilsson, “Cognition and its Object,” in Lloyd P. Gerson, ed., The Cambridge Companion to Plotinus (Cambridge: Cambridge U.P., 1996), pp. 217–49, esp. pp. 245–49. But see, Lloyd P. Gerson, Plotinus (London: Routledge, 1994), p. 227, n.3, who maintains that Plotinus is not an idealist. Similarly, in a 1989 study, I argued not only that idealism was a genuine possibility in late classical and in medieval philosophy, but that that the ninth-century Carolingian philosopher Johannes Eriugena presents a striking example of an extremely radical, almost fantastical, idealism.Dermot Moran, The Philosophy of John Scottus Eriugena. A Study of Idealism in the Middle Ages (Cambridge: Cambridge U.P., 1989). Of course, the whole discussion depends entirely on what is meant by ‘idealism’. Burnyeat uses Berkeley’s immaterialism as his standard for idealism, and it is this decision, coupled with his failure to acknowledge the legacy of German idealism, which prevents him from seeing the classical and medieval roots of idealism more broadly understood.

This book deals with Eriugena's view of man in the context of his thinking on universal nature.

This book deals with Johannes Scottus Eriugena, an Irish scholar at the Court of Charles the Bald in France in the second half of the ninth century - to be clearly distinguished from John Duns Scotus, after whom `Scotist' philosophy is named. Eriugena's main work, Periphyseon, is a remarkable attempt at a real intellectual synthesis between the Bible and Neoplatonist philosophy. It was not looked upon with great favour in the West except by the mystics and, more (...) recently, by German Idealist philosophers of the last century. Now, however, because of the growth of interest in Medieval Studies, there is an increasing curiosity about Eriugena and his work - but there has been no comprehensive book about him since that of M. Cappuyns in 1933. Bringing together the results of the most recent research on Eriugena, this book discusses his background in Ireland and life in France, and of his career as teacher, controversialist, translator, and poet. It gives an extended and careful summary of the Periphyseon, and the first translation into English of the brief Homily on the Prologue to St.John's Gospel. (shrink)

Abstrakt Der vorliegende Artikel befasst sich mit der Theorie des Schönen und der Schönheit im Denken des Johannes Scottus Eriugena, basierend auf seinem Hauptwerk Periphyseon, den ‚Aulae sidereae‘, einem Gedicht Eriugenas, und dem Kommentar zur Schrift ‚Über die himmlische Rangfolge‘ des Pseudo-Dionysius Areopagita. Dazu werden zunächst die metaphysischen Grundlagen für eine Theorie des Schönen im System des Eriugena, wie er sie im s.o. erarbeitet, kurz und prägnant vorgestellt: Für Eriugena ist das Seiende eine Erscheinung und Manifestation (...) Gottes, des unsagbaren Prinzips, des Einen. Danach wird aufgezeigt, wie Eriugena das Schöne als Konkretwerdung des Einen denkt, wobei zuerst die Schönheit der Natur besprochen wird, um dann einen Blick auf den Sonderfall der menschengemachten Kunst zu werfen. Das Ergebnis der Untersuchung ist, dass Eriugena die Kunst als eine reflexive Haltung des Menschen zur Welt und ihrem Ursprung versteht. (shrink)

Ancient Greek philosophers were the first to postulate the possibility of explaining nature in theoretical terms and to initiate attempts at this. With the rise of monotheistic religions of revelation claiming supremacy over human reason and envisaging a new world to come, studies of the natural order of the transient world were widely considered undesirable. Later, in the Middle Ages, the desire for human understanding of nature in terms of reason was revived. This article is concerned with the fundamental reversal (...) of attitudes, from "undesirable" to "desirable", that eventually led into the foundations of modern science. One of the earliest, most ingenious and most interesting personalities involved was Eriugena, a theologian at the Court of Charles the Bald in the 9th century. Though understanding what we call nature is only one of the several aspects of his philosophical work, his line of thought implies a turn into a pro-scientific direction: the natural order is to be understood in abstract terms of "primordial causes"; understanding nature is considered to be the will of God; man encompasses the whole of creation in a physical as well as a mental sense. Basically similar ideas on the reconciliation of scientific rationality and monotheistic religions of revelation were conceived, independently and nearly simultaneously, by the Arab philosopher al-Kindi in Bagdad. Eriugena was more outspoken in his claim that reason is superior to authority. This claim is implicit in the thought of Nicholas of Cusa with his emphasis on human mental creativity as the image of God's creativity; and it is the keynote of Galileo's "Letter to the Grand Duchess Christina" some 800 years later, the manifesto expressing basic attitudes of modern science.

Airuijiena is a medieval philosophy in the ninth century AD, the rise of a peak, it is the essence of mystical experience with God or with God, God included two adults and people of God into history. This article focuses on the Gospel of John describes Airuijiena Introduction sermons, also known as "Eagle Spirit Music," which contains the secret Qisi think, to be explored, but also involves its philosophy, theology and intellectual history of some of the relevant problem. This article (...) will first discuss the Airuijiena inherited traditions, such as the Irish spirit, Seven Arts in humanities education, Augustine Xing Greek Fathers, etc., and in "On the distinction between natural" will include them in a large integrated system. His "Gospel of St. John preaching preamble", or "Eagle Spirit Music," is a delicate little synthesis, which contains a wealth of secret Qisi want. This article will focus on St. John that he admired the mystical soul, show the people must continue to run away, until all finite things out, into the infinite God. This is a "self out of the" meaning of "extrapolation" of the most extreme, the most profound example. Then this paper to discuss Airuijiena by Zhu Zhong Jing's knowledge of God, to God and experience God together with their philosophical significance, particularly to understand the basis of the theory of divine light and darkness, which indicates not only the Word is the light itself, and all things even one grain of sand stone, they are the beacon. However, their theory of the divine darkness, God is also revealed that he is the ultimate person. In short, Airuijiena extrapolation of ideas and filled with the spirit of comparison, the system's deep and majestic, worthy I inspired. In the development of mediaeval philosophy, Johannes Scotus Eriugena stood like a "lofty rock in the midst of a plain", as Copleston puts it. His mysticism emphasized the union of God and Man in the double process of incarnation and deification. This paper will focus on his mysticism and its philosophical and historical implications in his Homily on the Prologue to the Gospel of St. John, also know as Vox Spiritualis Aquilae. We will discuss, first of all, what Eriugena had received from his Irish tradition, Neo-Platonism as interpreted by Greek fathers and St. Augustine and how he synthesized them into his Periphyseon. His Homily, as a marvelous work of synthesis in miniature, is very rich of mystic insights. We'll focus fist on his understanding of St. John's speculative mind, as a mind always going beyond itself that finally reaches the divine and thereby becomes deified in order to know God in himself. For me this is an extreme case of strangification. Then we will proceed to discuss Eriugena's mystic and philosophical concept of gnosis and theosis, and also his understanding of Logos as Light and that all things, even so tiny and low, are lights too. By contrast, his notion of Darkness of God leads us to the concept of God as totally Other , or the Ultimate Other. In sum, Eriugena's system of mystical philosophy is always deep and magnanimous, enough to inspire more generations to come. (shrink)

Engaging Eriugena, Eckhart and Cusanus contains two new essays and nine others published between 2005 and 2019. The essays explore Eriugena, Eckhart and Cusanus as bold thinkers deeply engaged with their times and culture. John Scottus Eriugena, Meister Eckhart and Nicholas of Cusa are key figures in the medieval Christian Neoplatonic tradition. This book focuses on their engagement with practical, experiential issues and controversies. Eriugena revises Genesis' Adam and Eve narrative and makes sexual difference and overcoming (...) it central to his Periphyseon. Eckhart's Annunciation sermons urge his hearers to give birth to God's son within their lives, and he develops a distinctive approach to pain and suffering. His radical preaching on the Eucharist and mystical union was judged heretical, but was later taken up by Nicholas of Cusa. Coins and banking became key symbols in Cusanus' exploration of humanity as created in God's image, and he used mechanical clocks in reflecting on time and eternity. 'Engagement' also describes these thinkers' reception of their predecessors and how later readers appropriated their works. Eriugena struggled with the legacy of Augustine and the Greek Fathers. Eckhart's theology of suffering provoked varied responses from his students Henry Suso and Johannes Tauler, and the twentieth-century therapist Ursula Fleming. Cusanus provides the volume's lynchpin as two articles analyse his reading of Eriugena and Eckhart, and a third discusses how he deftly countered Johannes Wenck's accusations of heresy. The book will be of interest to students of Medieval Philosophy, Theology, Spirituality and their place within Cultural History. (shrink)

The contributors cover a wide range of philosophical writers and texts to which the label “idealism” has been or might reasonably be attached. These include Plato, the Roman Stoics, the Neoplatonism of Plotinus, Augustinian Neoplatonism, Johannes Scottus Eriugena, the Arabic _Book of Causes_, George Berkeley, Immanuel Kant, and classical German idealism. "This is a rich, subtle, thought-provoking collection on central, though neglected topics in idealism and its history, offering fresh and important insights into both familiar and less familiar (...) major figures, views, and issues. Most important, perhaps, are its presentation and assessment of non-subjective forms of idealism, as well as mind-dependence forms of idealism prior to Descartes. Contemporary philosophers have become sophisticated about various forms of realism, anti-realism and irrealism. Such discussions, among others, will benefit significantly by accepting this volume’s invitation to become more sophisticated about idealism as well. This very welcome contribution to the literature should find a broad readership." —_Kenneth R. Westphal, University of East Anglia_ "If it is true—as Hegel and his followers have claimed—that being and truth are indissociable from history, then philosophy cannot be successful if it limits itself exclusively to investigations of individual thinkers and periods. What is at stake, ultimately, is the development of Western thought as a whole. In this volume, a fine international group of scholars investigate the meaning of idealism across the ages. Without sacrificing nuance, their contributions show that a core of shared assumptions characterizes idealist philosophies. The historical dialogue which this volume advances emphasizes the relevance of ancient and medieval thinkers for the current debate, but it also challenges us to place modern representatives of idealism—such as Berkeley, Kant, and Hegel—in historical perspective." —_Philipp W. Rosemann, University of Dallas_. (shrink)

Addressed to historians of medieval and Byzantine thought, philosophers and theologians, Eriugena: East and West provides an in-depth study of how the great Irish scholar, John Scottus Eriugena, bridged the gap between Eastern, Greek-speaking Christianity and the Latin West.

This volume provides a brief and accessible introduction to the 9th-century philosopher and theologian John Scottus Eriugena--perhaps the most important philosophical thinker to appear in Latin Christendom in the period between Augustine and Anselm. Eriugena was known as the interpreter of Greek thought to the Latin West, and this book emphasizes the relation of Eriugena's thought to his Greek and Latin sources.

This is an informative book dealing with a little known philosopher, Johannes Scottus Eriugena. In his first chapter O'Meara gives a succinct yet scholarly account of the historical context of Eriugena's writings--ninth-century Ireland and France. In particular O'Meara stresses that in that century there is abundant evidence that the Irish knew Greek and certainly the groundwork of Eriugena's later knowledge of Greek, evidenced in his translation of Pseudo-Dionysius, could have been laid in the Irish monastic schools. (...) Eriugena emerges in history as a liberal arts teacher and theological polemicist, and O'Meara's second and third chapters deal with these aspects of his career. Eriugena engaged in a theological dispute on the meaning of divine predestination, in which he argued against the view of Gottschalk that there was a double predestination, and propounded his own radical view that God is identical with predestination. In other words, all beings tend towards God, they are damned not by God but by their own perverse will. (shrink)

Quiero sostener en este artículo (en contra de la posición de Myles Burnyeat) que el idealismo es una posibilidad filosófica genuina previa a Descartes. En efecto, podemos encontrar una versión del idealismo que supone un concepto desarrollado de subjetividad en una sofisticada versión del Periphyseon de Escoto Eriúgena. El inmaterialismo intelectualista extremo de Eriúgena difiere del idealismo moderno en la medida en que aquél no está motivado tanto por una consideración epistemológica de argumentos escépticos relacionados con la existencia del mundo (...) externo, cuanto por una consideración más bien teológica de las consecuencias de la doctrina de la creación divina. Eriúgena considera que el mundo es una expresión de la mente divina y que todas las cosas en él están contenidas en la mente divina. Más aun, siguiendo la tradición neoplatónica, niega la existencia de la materia como un principio independiente y considera que la creatio ex nihilo significa creatio ex deo.---“Idealism in Medieval Philosophy: The Case of Johannes Scottus Eriugena”. In this paper, I wish to argue (against Myles Burnyeat) that idealism is a genuine philosophical possibility prior to Descartes. Indeed, a version of idealism which implies a developed concept of subjectivity is actually to be found in a sophisticated version in the Periphyseon of Johannes Scottus Eriugena. Eriugena’s extreme intellectualist immaterialism differs from modern idealism in that it is motivated not so much by an epistemological consideration of skeptical arguments concerning the existence of the external world, but rather by theological consideration of the consequences of the doctrine of divine creation. Eriugena thinks of the world as an expression of the divine mind, and of all things in the world as contained in the divine mind. Furthermore, following the Neoplatonic tradition, he denies the existence of matter as a separate principle, and considers creatio ex nihilo to mean creatio ex deo. (shrink)

This thesis is a study of the philosophical system of a little-studied, but important medieval thinker, John Scottus Eriugena , concentrating on his Periphyseon . ;I argue that Eriugena's system of nature must be approached through an investigation of his epistemology and general philosophy of mind. Instead of beginning with his fourfold classification of Nature, as most commentators have done, I begin with Eriugena's concept of the mind and its dialectical operations , and continue with an examination (...) of his anthropology , and his concept of self-knowledge , before turning to his relativist ontology of being and non-being . Chapter Seven examines Eriugena's fourfold division of Nature in the light of the earlier chapters. ;Against some recent commentators, I argue that Eriugena should not be interpreted solely from within the framework of the Latin-Augustinian metaphysical tradition of the early Middle Ages, that it was his sympathy for Greek Christian Neoplatonism which led him to develop an idealist philosophical outlook . Eriugena synthesises the Greek Eastern and the Latin Western traditions into a profound and original philosophical system. ;I show further that Eriugena "deconstructs" Latin metaphysical realism in favour of his own "me-ontology" or "meta-ontology," inspired by the Greeks. He produces the most detailed account of non-being between Plato's Parmenides and the phenomenologies of nothingness of Heidegger and Sartre. ;The summit of Eriugena's system is infinite Non-being, or infinite self-identical subjectivity. This philosophy bears strong similarities to post-Kantian critical philosophy, especially the Idealism of Fichte, Schelling and Hegel. My interpretation thus agrees with the nineteenth-century Idealist reading of Eriugena. At the same time, it suggests the implications of Eriugena's idealism for the interpretation of certain modern philosophies. (shrink)

This paper argues against the call to democratize artificial intelligence (AI). Several authors demand to reap purported benefits that rest in direct and broad participation: In the governance of AI, more people should be more involved in more decisions about AI—from development and design to deployment. This paper opposes this call. The paper presents five objections against broadening and deepening public participation in the governance of AI. The paper begins by reviewing the literature and carving out a set of claims (...) that are associated with the call to “democratize AI”. It then argues that such a democratization of AI (1) rests on weak grounds, because it does not answer to a demand of legitimization, (2) is redundant in that it overlaps with existing governance structures, (3) is resource intensive, which leads to injustices, (4) is morally myopic and thereby creates popular oversights and moral problems of its own, and finally, (5) is neither theoretically nor practically the right kind of response to the injustices that animate the call. The paper concludes by suggesting that AI should be democratized not by broadening and deepening participation but by increasing the democratic quality of the administrative and executive elements of collective decision making. In a slogan: The question is not so much whether AI should be democratized but how. (shrink)

It is necessary to consider medieval Western Neoplatonism as a current of thought inserted in a wide cultural atmosphere where liturgical, theological, aesthetic, and artistic patterns play an important role as elements of a common historical past. In this article the author argues to what extent Neoplatonic concepts (Epiphany, Negative Theology, Theology of Light and Metaphor of Light) derived from Johannes Scotus Eriugena, translator of the Corpus Areopagiticum into latin, relate to the Iconography of Crist-Light or Maiestas domini (...) in a mandorle of light. Writings of various thinkers, paintings from the 12th century and medieval epigraphy are taken as primary sources in order to understand the relationship between Neoplatonism and Iconography in the European Middle Ages.

In “Some Remarks on Extending and Interpreting Theories with a Partial Truth Predicate”, Reinhardt [21] famously proposed an instrumentalist interpretation of the truth theory Kripke–Feferman ( $\mathrm {KF}$ ) in analogy to Hilbert’s program. Reinhardt suggested to view $\mathrm {KF}$ as a tool for generating “the significant part of $\mathrm {KF}$ ”, that is, as a tool for deriving sentences of the form $\mathrm{Tr}\ulcorner {\varphi }\urcorner $. The constitutive question of Reinhardt’s program was whether it was possible “to justify the (...) use of nonsignificant sentences entirely within the framework of significant sentences”. This question was answered negatively by Halbach & Horsten [10] but we argue that under a more careful interpretation the question may receive a positive answer. To this end, we propose to shift attention from $\mathrm {KF}$ -provably true sentences to $\mathrm {KF}$ -provably true inferences, that is, we shall identify the significant part of $\mathrm {KF}$ with the set of pairs $\langle {\Gamma, \Delta }\rangle $, such that $\mathrm {KF}$ proves that if all members of $\Gamma $ are true, at least one member of $\Delta $ is true. In way of addressing Reinhardt’s question we show that the provably true inferences of suitable $\mathrm {KF}$ -like theories coincide with the provable sequents of matching versions of the theory Partial Kripke–Feferman ( $\mathrm {PKF}$ ).

The purpose of the present mixed method study was to investigate personal benefits, perceptions, and the effect of a 15-week sport psychological skills training program adapted for musicians. The program was individually tailored for six music performance students with the objective of facilitating the participants' instrumental practice and performance. The participants learnt techniques such as goal setting, attentional focus, arousal regulation, imagery, and acceptance training / self-talk. Zimmerman's ( 1989 ) cyclical model of self-regulated learning was applied as a theoretical (...) frame for the intervention. The present study's mixed-method approach (i.e., quan+ QUAL) included effect size, semi-structured interviews, a research log, and practice diaries of the participants (Creswell, 2009 ). Thematic analysis revealed that participants had little or no experience concerning planning and goal setting in regard to instrumental practice. Concentration, volition, and physical pain were additional issues that the participants struggled with at the time of pre-intervention. The study found that psychological skills training (with special emphasis on planning and goal setting) facilitated cyclical self-regulated learning patterns in the participants. In essence, the intervention was found to facilitate the participants' concentration, self-observation, self-efficacy, and coping in the face of failure. The appliance of practice journals facilitated the participants‘ self-observation, self-evaluation, and awareness of instrumental practice. Finally, the psychological skills intervention reduced participants' worry and anxiety in performance situations. An 8-month follow up interview revealed that the participants were still actively applying psychological skills. (shrink)
