Despite his prominent role in the formation of Christian thought, John Scottus Eriugena still remains an enigmatic figure whose background and potential arouse a great deal of scholarly interest. This is true especially today, when faith seeks to regenerate: his honesty and profundity encourage us in our search for the authentic teaching of Christ. As a theologian who strongly believes in human dignity as equal to that of the imago dei, Eriugena helps us meet Christ again and follow him towards a new horizon of being. What makes Eriugena’s theology unique is his innovative approach to theological thinking, which is to be properly understood, as argued in this book, in terms of the paradigmatic shift from metaphysics to dialectic. The way we think, while trying to adopt and follow the truth of revelation so as to get freed from the world of finite things, cannot actually dispense with a dialectical treatment of contradiction. And Eriugena is explicit about this, which allows him to win a reputation as the “Hegel of the ninth century” and to make us look at our faith anew in coherence with such pivotal ideas as the divine unity, right reason, and return to the reality of creation.

This work is a substantial contribution to the history of philosophy. Its subject, the ninth-century philosopher John Scottus Eriugena, developed a form of idealism that owed as much to the Greek Neoplatonic tradition as to the Latin fathers and anticipated the priority of the subject in its modern, most radical statement: German idealism. Moran has written the most comprehensive study yet of Eriugena's philosophy, tracing the sources of his thinking and analyzing his most important text, the Periphyseon. This volume will be of special interest to historians of mediaeval philosophy, history, and theology.

Revisiting the history of Western religious thought and the role of nature and creation therein, this book paves the way for a new natural theology by bringing medieval theologian John the Scot Eriugena into conversation with American philosopher Ralph Waldo Emerson.

John Scottus Eriugena (d. ca. 877) is regarded as the most important philosopher and theologian in the Latin West from the death of Boethius until the thirteenth century. He incorporated his understanding of Latin sources, Ambrose, Augustine, Boethius and Greek sources, including the Cappadocian Fathers, Pseudo-Dionysius, and Maximus Confessor, into a metaphysics structured on Aristotle’s Categories, from which he developed Christian Neoplatonist theology that continues to stimulate 21st-century theologians. This collection of essays provides an overview of the latest scholarship on various aspects of Eriugena’s thought and writings, including his Irish background, his use of Greek theologians, his Scripture hermeneutics, his understanding of Aristotelian logic, Christology, and the impact he had on contemporary and later theological traditions.

Unjustly ignored as a result of a 13th century condemnation, the thought of Johannes Scottus Eriugena (ca. 810-877) has only been subject to critical study in the 20th century. Now, with the completion of the critical edition of Eriugena's masterwork -- the Periphyseon -- the time has come to explore what is arguably the most intriguing and vital theme in his work: creation and nature. In honor of Edouard Jeauneau -- Institute Professor at the Pontifical Institute of Mediaeval Studies, University of Toronto and Honorary Research Director at the C.N.R.S. in Paris, to whom the field of Eriugenian studies is enormously indebted -- this volume seeks to undertake a serious examination of the centrality of Eriugena's thought within the Carolingian context, taking into account his Irish heritage, his absorption of Greek thought and his place in Carolingian culture; of Eriugena as a medieval thinker, both his intellectual influences and his impact on later medieval thinkers; and of Eriugena's reception by modern philosophy, from considerations of philosophical idealism to technology.

The medieval Christian West's most radical practitioners of a Neoplatonic, negative theology with a mystical focus are John Scottus Eriugena, Meister Eckhart and Nicholas Cusanus. All three mastered what Cusanus described as docta ignorantia: reflecting on their awareness that they could know neither God nor the human mind, they worked out endlessly varied attempts to express what cannot be known. Following Pseudo-Dionysius the Areopagite, they sought to name God with symbolic expressions whose negation leads into mystical theology. For within their Neoplatonic dialectic, negation moves beyond reason and its finite distinctions to intellect, where opposites coincide and a vision of God's infinite unity becomes possible. In these papers Duclow views these thinkers' efforts through the lens of contemporary philosophical hermeneutics. He highlights the interplay of creativity, symbolic expression and language, interpretation and silence as Eriugena, Eckhart and Cusanus comment on the mind's work in naming God. This work itself becomes mystical theology when negation opens into a silent awareness of God's presence, from which the Word once again 'speaks' within the mind - and renews the process of creating and interpreting symbols. Comparative studies with Gregory of Nyssa, Pseudo-Dionysius, Anselm and Hadewijch suggest the book's wider implications for medieval philosophy and theology.
