John Scottus Eriugena
First published Thu Aug 28, 2003; substantive revision Wed Oct 30, 2019 Johannes (c–c), who signed himself as “Eriugena” in one manuscript, and who was referred to by his contemporaries as “the Irishman” (scottus—in the ninth century Ireland was referred to as “Scotia Maior” and its inhabitants as “scotti”) is the most significant Irish intellectual of the early monastic period. He is generally recognized to be both the most outstanding philosopher (in terms of originality) of the Carolingian era and of the whole period of Latin philosophy stretching from Boethius to Anselm. Eriugena is, also, though this parallel remains to be explored, more or less a contemporary of the Arab Neoplatonist Al-Kindi. Since the seventeenth century, it has become usual to refer to this Irish philosopher as John Scottus (or “Scotus”) Eriugena to distinguish him from the thirteenth-century John Duns Scotus (see entry). Eriugena’s uniqueness lies in the fact that, quite remarkably for a scholar in Western Europe in the Carolingian era, he had considerable familiarity with the Greek language, affording him access to the Greek Christian theological tradition, from the Cappadocians to Gregory of Nyssa, hitherto almost entirely unknown in the Latin West. He also produced a complete, if somewhat imperfect, Latin translation of the Corpus Dionysii, the works of the obscure, possibly Syrian, Christian Neoplatonist, Pseudo-Dionysius the Areopagite, a follower of Proclus. In addition, Eriugena translated Gregory of Nyssa’s De hominis opificio and Maximus Confessor’s Ambigua ad Iohannem, and possibly other works, such as Epiphanius’ Anchoratus. Eriugena’s thought is best understood as a sustained attempt to create a consistent, systematic, Christian Neoplatonism from diverse but primarily Christian sources. Eriugena had a unique gift for identifying the underlying intellectual framework, broadly Neoplatonic but also deeply Christian, assumed by the writers of the Christian East. Drawing especially on Basil, Gregory of Nyssa, Pseudo-Dionysius the Areopagite, Maximus Confessor, as well as on the more familiar authorities (auctores) of the Latin West (e., Cicero, Augustine, Macrobius, Martianus Capella, Boethius), he developed a highly original cosmology, where the highest principle, “the immovable self-identical one” (unum et idipsum immobile, Periphyseon, Patrologia Latina 122: 476b), engenders all things and retrieves them back into itself. Contrary to what some earlier commentators supposed, it is most unlikely that Eriugena had direct knowledge of the original texts of Plotinus, Porphyry, Proclus, or other pagan Neoplatonists, but he did have some direct knowledge of Plato (a portion of Timaeus in the translation of Calcidius) as well as familiarity with the pseudo-Augustinian Categoriae decem. Overall, Eriugena develops a Neoplatonic cosmology according to which the infinite, transcendent, and “unknown” God, who is beyond being and non-being, through a process of self-articulation, procession, or “self-creation”, proceeds from his divine “darkness” or “non-being” into the light of being, speaking the Word who is understood as Christ, and at the same timeless moment bringing forth the Primary Causes of all creation. These causes in turn proceed into their Created Effects and as such are creatures entirely dependent on, and will ultimately return to, their sources, which are the Causes or Ideas in God. These Causes, considered as diverse and infinite in themselves, are actually one single principle in the divine One. The whole of reality or nature, is involved in a dynamic process of outgoing (exitus) from and return (reditus) to the One. God is the One or the Good or the highest principle, which transcends all, and which therefore may be said to be “the non-being that transcends being”. In an original departure from traditional Neoplatonism, in his dialogue Periphyseon, this first and highest cosmic principle is called “nature” (natura) and is said to include both God and creation. Nature is defined as universitas rerum, the “totality of all things”, and includes both the things which are (ea quae sunt) as well as those which are not (ea quae non sunt). This divine nature may be divided into a set of four “species” or “divisions” (divisiones) which nevertheless retain their unity with their source. These four divisions of nature taken together are to be understood as God, presented as the “Beginning, Middle, and End of all things”.
Apart from having a minor influence in France in the ninth century, Eriugena’s cosmological speculations appear too conceptually advanced for the philosophers and theologians of his time, and his philosophical system was generally neglected in the tenth and eleventh centuries. His main work, Periphyseon, was revived by twelfth-century Neoplatonists, and also circulated in a compendium, Clavis Physicae (The Key of Nature) of Honorius Augustodunensis. The Periphyseon was popular among the philosophers of Chartres and St. Victor (e., Hugh of St. Victor refers to it) but was condemned in the thirteenth century, alongside the writings of David of Dinant and Amaury of Bène, for promoting the identity of God and creation. In the fourteenth and fifteenth centuries, Eriugena continued to have a relatively clandestine but still important influence on Christian Neoplatonists such as Meister Eckhart and especially Nicholas of Cusa. The first printed editions of his works appeared in the seventeenth century, but it was not until the nineteenth century that interest in him was revived, especially among followers of Hegel who saw Eriugena as a forerunner to speculative idealism, as a “Proclus of the West” (Hauréau, 1872) and the “Father of Speculative Philosophy” (Huber, 1861). The first truly scholarly attempt to establish the facts of his life, his works and influence was by the Belgian scholar Maiul Cappuyns, whose 1933 work Jean Scot Erigène: sa vie, son oeuvre, sa pensée is still reliable. Many valuable twentieth-century studies (e., Contreni, 1992; Marenbon, 1981, 2006; Schrimpf, 1982; O’Meara, 1969, 1988) have explored Eriugena’s Carolingian background and continuity with Latin authors. However, systematic studies of his thought (Beierwaltes, 1980, 1987, 1990; Gersh, 1978, 2006; Moran, 1989, 1999) have also recognized him as a highly original metaphysician and speculative thinker of the first rank whose work transcends the limitations of his age and mode of expression. 1.

1. Life and Writings
1 Eriugena as Liberal Arts Master
transcendence, and goodness. While purporting merely to interpret Augustinian texts, this early theological treatise is philosophically significant for its rationalistic, dialectical analysis of key theological concepts and its reliance on argument rather than scriptural citation. In this treatise, Eriugena, citing Augustine’s De uera religione 5, PL 34: 126, claims “that true philosophy is true religion and conversely that true religion is true philosophy”. As one gloss in the Annotationes in Marcianum attests: “no one enters heaven except through philosophy” (nemo intrat in celum nisi per philosophiam, Annotationes 57, AM: 64). Eriugena then argues that philosophy has four principal parts—division, definition, demonstration, and resolution—and the pursuit of this fourfold method of reasoning will lead to truth. This focus on dialectic as the path to truth is a constant theme of Eriugena’s philosophy, one recognized by his contemporaries. Eriugena argues in De divina praedestinatione that God, being perfectly good, wants all humans to be saved, and does not predestine souls to damnation. God’s being is His willing and “no necessity binds the will of God”. On the contrary, humans damn themselves through their own free choices: “Sin, death, unhappiness are not from God”. Since God is outside time, He cannot be said to fore-know or to pre-destine, terms that involve temporal predicates. Furthermore, if God’s being is His wisdom, God can be said to have but a single knowledge and hence a “double” predestination cannot be ascribed to Him. Human nature, on the other hand, was created rational, and rationality requires freedom. Human nature is therefore essentially free: “For God did not create in man a captive will but a free one, and that freedom remained after sin” (De divina praedestinatione, 4). In the course of his diatribe against the “ravings” of Gottschalk, Eriugena locates his opponent’s heresy as midway between the heresy of Pelagius, which rejects the power of grace, and the opposing heresy, which denies the possibility of human freedom. Ironically, Eriugena himself would in turn be accused of “Origenism” and “Pelagianism” by Gottschalk’s advocate, Bishop Prudentius of Troyes (see the latter’s De Praedestinatione, PL 115: 1010c), due to his perceived emphasis on human free-will in the salvific process. Prudentius, an erstwhile admirer of Scottus, published an opposing treatise, which, while acknowledging his “Irish eloquence” (Celtica eloquentia, PL 115: 1194a), dismisses Eriugena’s reasoning as confused and not based on sound knowledge of scripture. Florus too attacked Eriugena. Subsequently, On Divine Predestination was condemned by the bishops in France at the councils of Valence (855) and Langres (859), in part for its over-use of logical method or dialectic (dialectica). The phrase “Irish porridge” (pultes scottorum), recalling Jerome’s sneer against Pelagius, is used in these official denunciations.
1 Eriugena as Translator
Despite the official ecclesiastical condemnations of On Predestination, for reasons that are not known but are presumed to be political, Eriugena continued to have the protection and patronage of King Charles the Bald, who, around 860, invited him to translate the writings of Pseudo-Dionysius the Areopagite, a mysterious Christian Neoplatonist who purported to be Dionysius, the first convert of St. Paul at Athens, but was more likely a late fifth or early sixth-century Christian follower of Proclus. The Corpus Dionysii had been given a gift to Charles the Bald’s father, Louis the Pious, from the Byzantine Emperor Michael the Stammerer in 827, a gift thought appropriate possibly because of a misidentification of Pseudo-Dionysius with the patron saint of France, St. Denis. Hilduin had attempted an earlier translation in 832–5, but Eriugena’s version was most successful and remained in circulation until the thirteenth century when Jean Sarrazin’s translation replaced it. Indeed, Eriugena’s translation was utilized by the Vatican Librarian Anastasius, who added scholia to it. Anastasius decried the word-for-word translation, however he contributed to it, thereby indicating its importance (Harrington, 2004). Soon after completing his translation of Pseudo-Dionysius (c. 862), he went on to translate other Greek Christian texts: he translates Maximus Confessors’ Ambigua ad Ioannem and then his Quaestiones ad Thalassium; Gregory of Nyssa’s De hominis opificio, under the title of De imagine and possibly Epiphanius’ Anchoratus de Fide. Eriugena also wrote a long commentary on Pseudo-Dionysius’ Celestial Hierarchy (Expositiones in hierarchiam coelestem). It is possible he made other translations which have not survived or which cannot be definitively attributed to him, e., Boethius’ De musica.
1 The Dialogue Periphyseon (On the Division of Nature)—The Manuscripts
Eriugena’s major work, the Periphyseon, also titled in some manuscripts, De divisione naturae (On the Division of Nature), is a long dialogue between a “teacher” (Nutritor) and a “student” (Alumnus), was probably begun in the early 860s, just after he had completed the Pseudo-Dionysius translation, and finished around 867 (the date Wulfad, to whom the work is dedicated, became bishop, making it unlikely that Eriugena would have referred to him as frater, brother,
after his consecration as bishop). The first printed edition of this dialogue appeared in 1681 and subsequently an edition by Floss appeared in 1853 which is now contained in PL 122. Inglis Patrick Sheldon-Williams (1908–1973) began a new edition of Periphyseon with the publication of his text and translation of Book One in 1968 in the Scriptores Latini Hiberniae series of the Dublin Institute of Advanced Studies, followed soon after by his edition of Periphyseon Book Two in 1970, and Book Three, published after Sheldon-Williams’ death, in the same series in 1981, seen through the press by the late John J. O’Meara. Sheldon-Williams had assembled materials for the edition of Books Four and Five and had completed a draft English translation of these books, which was published separately in one volume edited by John J. O’Meara. O’Meara and Édouard Jeauneau continued the edition of Sheldon-Williams, bringing out Book Four in the same series in 1995. However, due to some deficiencies in Sheldon-Williams’ manner of editing, and his mistaken conception of the manuscript tree, Jeauneau has undertaken an entirely new critical edition of the Periphyseon for the Corpus Christianorum Continuatio Mediaevalis series. All five books of the Periphyseon have appeared in this series. Sheldon-Williams was of the opinion that Periphyseon Book One had emerged from an earlier “essay in dialectic”, but offered no evidence for this interpretation, which takes an overly restrictive view of the first book of the dialogue. The main weakness of Sheldon-Williams’ editing strategy was that it had conflated various versions of the text drawn from several different manuscripts into a single composite script, in a similar manner to the earlier editors, Thomas Gale in 1681 and H.-J. Floss in 1853. Gale and Floss had published editions that combined into a single text both the text of the main body of the manuscript and the various marginal annotations in different hands. This composite version disguised the gradual evolution of the text and Jeauneau is of the opinion that this mixed type of edition is inadequate to the needs of scholarship. The new Jeauneau edition is based on six manuscripts, including two manuscripts, Paris Bibl. nat. lat. 12965 and Bamberg Phil. 2/2, not used by Sheldon-Williams since they contained only Books Four and Five. Jeauneau has suggested that the extant manuscripts of the Periphyseon show four distinct levels of development, that is, four early “editions”. One special difficulty in editing the Periphyseon is that the earliest manuscripts preserve only the first three books whereas the extant manuscripts for Books Four and Five date from the twelfth century. Avranches and Cambridge, both twelfth century manuscripts, are the sole witnesses for the end of Book Four and the whole of Book Five in Stage Two versions, with Avranches noticeably less accurate than Cambridge in several places.
1 Other Writings
A fragmentary Commentary on the Gospel of St. John (Commentarius in Evangelium Iohannis) and a sermon (Homilia in Johannem) on the Prologue to St. John’s Gospel were also written probably in the late 860s or 870s. A number of interesting poems (Carmina) survive which show the breadth of Eriugena’s learning; but also portray him as a courtier quite well versed in political affairs. Some poems are written specifically in praise of the king, including an important poem, Aulae sidereae (Starry Halls) which appears to celebrate the dedication of Charles the Bald’s new church in Compigne on 1 May 875. The poems show Eriugena’s fascination with Greek and some poems are actually written entirely in Greek; and the poems are probably the most Maximean in character through their cosmic Christology. It is probable that Eriugena died sometime around 877. An apocryphal tale, dating from the twelfth century, records that Eriugena was stabbed to death by his students with their pens!
2. Eriugena’s Sources
Despite the claims of some nineteenth-century commentators, it is now clear that Eriugena did not have direct knowledge of the writings of Plotinus, Porphyry, or Proclus. He had almost no contact with pagan Neoplatonism in general (apart possibly from Priscianus Lydus and Calcidius’ translation of the Timaeus). His familiarity with Aristotle was also indirect—through the anonymous but widely circulated compilation, Categoriae decem, the Pseudo- Augustinian paraphrase of Aristotle’s Categories. He knew Boethius’ trinitarian tracts (Opuscula sacra) and possibly the Consolation of Philosophy, since a set of glosses on this work may be in Eriugena’s hand (although this is disputed). His chief authorities in the Latin Christian Tradition were the works of the Fathers, chiefly Augustine (especially his De Genesi ad litteram), Ambrose, Hilary of Poitiers, and Jerome. His originality is largely due to the manner in which he assimilated (often translating) the Neoplatonic thought of Eastern Christian writers such as the Cappadocians, Basil the Great, Gregory of Nyssa, Gregory Nazianzus, as well as Pseudo-Dionysius the Areopagite and Maximus Confessor. He also was familiar with Rufinus’ Latin translation of Origen’s On First Principles and was often linked with Origen in medieval times. Though he took the view that the authorities of East and West were not in conflict, nevertheless he usually expressed a preference for the Eastern Church Fathers. An especially important authority was Maximus Confessor, whose account of the return of all things Eriugena copiously borrowed. Eriugena’s exceptional learning would be sufficient to distinguish him from contemporary Carolingian scholars, such as Alcuin and Sedulius Scottus; but his true and lasting genius lay in his ability to combine elements from these auctores
2 Maximus Confessor
Although he has recourse to Maximus Confessor hoping that he might offer some clarifications for understanding Pseudo-Dionysius, Maximus will offer Eriugena much more: a trove of ideas, methods, and philosophical vocabulary. Thus, Maximus allows him to expand and clarify the insights received from Dionysius and provides him with an eclectic philosophical and theological vocabulary: the Maximian oeuvre offers a palimpsest of Neo-Aristotelian and Neoplatonic philosophical terms and concepts along with a rich theological vocabulary which is mostly a synthesis of terms and concepts derived from Pseudo-Dionysius and the Cappadocian Fathers (Gregory Nazianzus, Gregory of Nyssa, and Basil the Great). The very method of the Periphyseon, which employs natural philosophy and exegesis of the Bible interchangeably, in order to contemplate and “read” the two “books” (creation and Scripture) in which the divine signs (theophanies) are manifested, can be traced back to Maximus’ notion of knowledge as contemplation of nature (theoria physikè). If contemplated and read from the right perspective, scripture and creation become transparent to divine presence. Eriugena adopts the cosmological framework of Maximus’ Christian Neoplatonism: the cosmic movement of exitus becomes the incarnation, the mystery of Christ becoming man; reditus, the return of all beings to their source, coincides with deification, humans ascending to God through deification (θέωσις). Eriugena will go further and correlate these cosmic movements with the two main operations of dialectic: division and analysis; this allows him to construct a deep correspondence between epistemology and ontology. Thus, Maximus’ cosmic Christology based on the Logos-logoi ontology, offers Eriugena a framework which allows him to expand the use of dialectic from mere method to a cosmic framework which underlies both epistemology and ontology. Maximus’ understanding of the incarnation as a cosmic event informs Eriugena’s ontology and his notion of theophanic creation; although the notion of theophany is first derived from Dionysius, it is enhanced through Maximus’ understanding of the incarnation of Christ as a cosmic mediation and unification of all aspects and levels of reality. Through the ideas of Pseudo-Dionysius and Maximus, Eriugena overcomes the distrust of visible and material nature found in Neoplatonism; rather he believes contemplating the theophanies encountered in nature (which has been redeemed through the incarnation of the Logos) is necessary for the return of creation to its divine source. Eriugena’s anthropology is based on Maximus’ insight that the human being is a synthesis of all aspects of creation, as he says, the “workshop of creation“ (officina omnium) and as such plays a crucial role in unifying creation through proper knowledge; the entire dialogue of the Periphyseon could be seen as a spiritual exercise (exercitatio animi) of training through the liberal arts in order to attain the level of intellectual knowledge; the goal of exercitatio is to contemplate nature in the right way in order to repair the fragmentation of creation by achieving a unified vision and thus realize the return of all things to their divine source. The human being as officina omnium plays a central role in the process of return (reditus) because as a primordial idea in the divine mind, it can mediate between the primordial causes and the created effects. However, only through the incarnation (in which Christ assumes human nature in its totality), can the full, cosmic scope of this process of mediation and unification through the human being as officina omnium be realized: through the incarnation of Christ the Logos, the universal human nature and through it the rest of creation is unified, redeemed and ultimately divinized. [see also section 3 Human Nature]
2 Augustine
The Periphyseon as a grand dialogue on physiology (physiologia is Eriugena’s hybrid science of physics-theology- philosophy) stands in continuity with the exercitatio animi and the liberal arts tradition of Augustine’s early philosophical dialogues. Eriugena appropriates and expands on Augustine’s trust that reason (ratio) can be trained by the liberal arts and can thus contemplate creation. Augustine’s intellectualism is crucial for Eriugena’s philosophical anthropology although Eriugena seems to be much more trusting than Augustine in the ability of the human to refashion itself through paideia. Informed by Dionysius notion of theophanic cosmic order, Eriugena is more comfortable with the complexities of Neoplatonic cosmology and with mediation (medietas) and less preoccupied with the issue of divine simplicity. Nevertheless, the Augustinian strain is not lost in Eriugena: both the human being and the creation have a Trinitarian structure. Along with Basil the Great, it is Augustine (through his great commentary on Genesis, De Genesi ad litteram) who teaches Eriugena to read and interpret the Hexaemeron (the creation account in Genesis 1) in a more literal and realistic manner and thus to counter-balance the more allegorical reading of Gregory of Nyssa; Augustine constitutes
both a foil and a catalyst for Eriugena’s thinking; his great challenge in the Periphyseon is trying to reconcile the Augustinian perspective with that of the Eastern thinkers. Augustine’s concept of the primordial causes (primordiales causae ) along with Maximus’ concept of logoi allow Eriugena to forge a realistic ontology based on intelligible species of visible things which are immanent in created beings (see Erismann, 2011).
2 Gregory of Nyssa, Gregory of Nazianzus and Basil the Great
Eriugena cites almost 25% of Gregory of Nyssa’s De Imagine—as he refers to the De hominis opificio—in the Periphyseon. Gregory of Nyssa’s and Basil the Great’s accounts of creation provide the missing pieces, and complements the cosmology Eriugena derives from the partial Latin translation of the Timaeus. Basil’s Homilies on the Hexaemeron provide him with a model for reading Genesis literally. Gregory of Nyssa’s imago dei anthropology provides the scaffolding for Maximus’ understanding of the role and status of the human being. Eriugena extrapolates from both Gregory of Nazianzus’ view that the essence of God is ineffable and ultimately beyond definition and from Gregory of Nyssa’s apophatic anthropology; therefore, both the divine and the human are ultimately unfathomable and ineffable: as the image of God (imago dei), the human being in its essence is as incomprehensible and undefinable as God. The idea that the human being is uncircumscribed and indefinable is derived from Gregory of Nyssa, and Eriugena connects it with Maximus’ officina omnium view of the human being and with Augustine’s Trinitarian theology.
3. The Philosophical System of the Periphyseon
Eriugena’s masterpiece is undoubtedly the Periphyseon (written c–c), a long dialogue in five books—between an anonymous “teacher” (Nutritor) and his “student” (Alumnus)—that attempts to be a compendium of all knowledge presented within a Neoplatonic cosmology of the procession and return of all things from the divine One. The Periphyseon, deeply influenced by Eriugena’s engagement with Greek Christian authors, is a work of astonishing scope, a veritable Christian Neoplatonic summa. At the beginning of Book Four, Eriugena labels his enterprise a physiologia, a “study of nature”, and indeed one manuscript of the Periphyseon in the British Library in London calls the whole dialogue “Liber Phisiologiae Iohannis Scottigenae”. The term “physiologia” is apt in that the term “nature” for Eriugena spans the whole cosmological domain, including not just created nature but also the Divine Creator, and treats of the essentially dialectical relation between Creator and created, where God expresses Himself in creation and creation culminates in return to the divine. Nature is to be understood as what is real in the widest sense, the totality of all things that are and are not. Nature includes both God and creation and has four divisions: nature which creates and is not created (God), nature which creates and is created (the Primordial Causes), nature which is created and does not create (the Created Temporal Effects), and nature which is neither created nor creates (Non-Being). The original intention (expressed at III–620b) was to devote one book to each of the four divisions; thus Book One deals with the divine nature and the procession or exitus of all things from God, Book Two treats of the Primordial Causes, and Book Three of their Created Effects, including the nature of ex nihilo creation and the stages of the creation of the world. The topic of creation requires Eriugena to address issues related to the Biblical account of creation, and thus, in Book Three, he embarks on his own version of a Hexaemeron. The momentous event of the emergence of human nature on the Sixth Day of creation requires extended treatment, and Eriugena is forced to devote a fourth book to this topic, thus relegating the return of all things to God to a fifth book. Thus, Eriugena was forced to depart from his original plan of four books and add a fifth. This change of plan is particularly important in that it helps to identify different stages of composition of the text. One of the most fascinating aspects of the Periphyseon is Eriugena’s ability to bring together into a symphony of ideas such a variety of thinkers and sources: the liberal arts and the philosophical dialogue traditions, the officina omnium anthropology of Maximus Confessor, the theophanic ontology of Dionysius the Areopagite, Augustine’s Trinitarian theology, Basil the Great’s realistic hermeneutics of the Hexaemeron, and Gregory of Nyssa’s imago dei anthropology and his account of creation; however, we may say that the grand tapestry of the Periphyseon is woven from many threads but the fabric is Maximian. Maximus Confessor’s vision provides the impetus that drives the argument of the dialogue and also the framework in which the encounter and conversation among the various sources takes place.
overt metaphysical statements. Thus when Eriugena calls God “nothing”, he means that God transcends all created being, God is nihil per excellentiam (“nothingness on account of excellence”) or, as he puts it, nihil per infinitatem (“nothingness on account of infinity”). Matter, on the other hand, is also called “nothing” but it is “nothing through privation” (nihil per privationem). Similarly, created things are called “nothing” because they do not contain in themselves their principles of subsistence (Eriugena is here repeating St. Augustine’s view that the creature, considered apart from God, is mere nothing).
3 The Attributes of God
Periphyseon Book One examines the first division, God understood as a transcendent One above, and yet cause of, all creation. God transcends everything; He is, following Pseudo-Dionysius, the “negation of all things” (negatio omnium, III). According to Eriugena—who in this respect is following a tradition which includes Augustine and Boethius as well as Dionysius and other Greek authors—the Aristotelian categories are considered to describe only the created world and do not properly apply to God (I). God cannot “literally” (proprie) be said to be substance or essence (ousia, essentia), nor can He be described in terms of quantity, quality, relation, place or time. He is “superessentialis” (I), a term which, for Eriugena, belongs more to negative theology than to affirmative. His “being” is “beyond being”. Eriugena particularly admires a Dionysian saying from the Celestial Hierarchy (CH iv 1; PG 3: 177d1–2): to gar einai panton estin he hyper to einai theotes (“for the being of all things is the Divinity above being”, III) which he translates as esse omnium est superesse divinitatis, (“the being of all things is the super-being of divinity”, III, I; see also I; III, V). This is perhaps Eriugena’s favorite phrase from Dionysius. (Indeed, Maximus Confessor had also commented on it in I Ambigua xiii, PG 91: 1225d, a passage well known to Eriugena who translated the Ambigua.) Sometimes, instead of invoking the Dionysian formula superesse divinitatis, Eriugena speaks of the “divine superessentiality” (divina superessentialitas, III), or—quoting Divine Names I 1–2 (PG 3: 588b–cb) —of the “superessential and hidden divinity” (superessentialis et occulta divinitas, I). God is a “nothingness” (nihilum) whose real essence is unknown to all created beings, including the angels (447c). Indeed, Eriugena argues in a radical manner, following Maximus Confessor, that God’s nature is infinite and uncircumscribable, such that He is unknown even to Himself, since He is the “infinity of infinities” and beyond all comprehension and circumscription. In the Periphyseon, Eriugena repeats the position of the De Praedestinatione that God does not know evil, and, in a genuine sense, God may be said not to know anything; his ignorance is the highest wisdom.
3 Creation as Divine Self-Manifestation
Eriugena conceives of the act of creation as a kind of self-manifestation wherein the hidden transcendent God creates himself by manifesting himself in divine outpourings or theophanies (I). He moves from darkness into the light, from self-ignorance into self-knowledge. The divine self-creation or self-manifestation (I) is, at the same time (or rather timelessly), the expression of the Word (Logos) and hence the creation of all other things, since all things are contained in the Word. The Word enfolds in itself the Ideas or Primary Causes of all things and in that sense all things are always already in God: .. Creative nature permits nothing outside itself because outside it nothing can be, yet everything which it has created and creates it contains within itself, but in such a way that it itself is other, because it is superessential, than what it creates within itself. (Periphyseon, III) God’s transcendent otherness above creatures is precisely that which allows creatures to be within God and yet other than God. Eriugena stresses both the divine transcendence above and immanence in creation. The immanence of God in the world is at the same time the immanence of creatures within God. Creatures however, as fallen, do not yet know that they reside in God. In cosmological terms, however, God and the creature are one and the same: It follows that we ought not to understand God and the creature as two things distinct from one another, but as one and the same. For both the creature, by subsisting, is in God; and God, by manifesting himself, in a marvelous and ineffable manner creates himself in the creature.... (Periphyseon, III) Elsewhere Eriugena’s asserts that God is the “essence of all things” (essentia omnium) and the “form of all things” (forma omnium). In the thirteenth century, expressions such as these led to the accusation of heresy, i., that Eriugena is collapsing the difference between God and creation. It must be noted, however, that although Eriugena asserts the
identity of God and creation, he explicitly rejects the view that God is the “genus” or “whole” (totum) of which the creatures are “species” or “parts”. Only metaphorically (metaforice, translative) can it be said that God is a “genus” or a “whole”. Assertions concerning the immanence of God in creation are always balanced in Eriugena’s writings by assertions of God’s transcendence above all things. God is both “form of all things” and also is without form, formless. Since God cannot be said to be anything, God cannot be simply identified with any or every creature either.
3 The Primordial Causes
The main focus of the Second Book of the Periphyseon is an analysis of what Eriugena terms “the Primary Causes” (causae primordiales) which are the patterns of all things located in the mind of God and function as the timeless and unchanging causes of all created things. This doctrine represents an eclectic combination of various earlier doctrines, including the Platonic theory of Forms or ideai, Dionysius’ discussion of the divine names, and Augustine’s revival of the Stoic notion of eternal reasons (rationes aeternae). God’s mind, understood as the logos or verbum, contains in one undivided Form all the reasons for every individual thing. These reasons (rationes, logoi) are productive of the things of which they are the reasons. Their number is infinite and none has priority over the other, e., Being is not prior to Goodness, or vice-versa. Each is a divine theophany, a way in which the divine nature is manifested. The very nature of these Causes is to flow out from themselves, bringing about their Effects. This “outflowing” (πρόοδος, proodos; processio, exitus) creates the whole universe from the highest genus to the lowest species and “individuals” (atoma). In his understanding of this causal procession, Eriugena accepts Neoplatonic principles: like produces like; incorporeal causes produce incorporeal effects; an eternal cause produces an eternal effect. Since the causes are immaterial, intellectual and eternal, so their created effects are essentially incorporeal, immaterial, intellectual, and eternal. Eriugena, however, thinks of cause and effect as mutually dependent, relative terms (Periphyseon, V. 910d–912b): a cause is not a cause unless it produces an effect, an effect is always the effect of a cause.
3 The Created Effects
What is the ontological status of the created effects? By nature, they are eternal and incorruptible, but Eriugena also thinks of individual created things as located spatially and temporally. He seems to think there are two kinds of time: an unchanging time (a reason or ratio in the divine mind,Periphyseon, V) and a corrupting time. Place and time are definitions in that they situate or locate the things they define, and since definitions are in the mind, then place and time are in the mind (Periphyseon, I). Following Gregory of Nyssa, Eriugena holds that the sensible, corporeal, spatio- temporal appearances of things are produced by the qualities or “circumstances” of place, time, position, and so on, which surround the incorporeal, eternal essence. The whole spatio-temporal world and our corporeal bodies are a consequence of the Fall, an emanation of the mind. Eriugena is somewhat ambiguous about this. His considered position appears to be that God, foreseeing that man would fall, created a body and a corporeal world for him. But this corporeal body is not essential to human nature and in the return of all things to God, the body will be absorbed back into the spiritual body (spirituale corpus) and the spiritual body back to the mind (mens, intellectus, νοῦς). The corporeal world will return to its incorporeal essence, and place understood as the extension will return back into its cause or reason as a definition in the mind (Periphyseon, V).
3 Creation from Nothing
Book Three discusses the nature of created effects and the meaning of “creation from nothing” (creatio ex nihilo). The term “nothing” has two meanings: it can mean “nothing through privation” (nihil per privationem), or “nothing on account of excellence” (nihil per excellentiam). The lowest rung in the hierarchy of being, unformed matter, is “almost nothing” (prope nihil), or “nothing through privation”. In contrast, God is non-being through the excellence of His nature which transcends all being. Since there is nothing outside God, “creation from nothing” cannot mean creation from some principle outside God, rather it means: creation out of God’s superabundant nothingness. God creates out of himself (a se) and all creation remains within him.
3 The Return of All Things
Books Four and Five, originally planned as one book, discuss the return (ἐπιστροφή, epistrophe, reditus, reversio) of all things to God. According to the cosmic cycle Eriugena accepts, drawing heavily on Maximus Confessor and his
But, according to the Church’s reasoning, the greatness of man lies not in his likeness to the created world but in the fact that he is created according to the image of the Creator of nature. (Periphyseon, IV) Eriugena, however, recognizes the crucial role of human nature in mediating between the divine and created things. Human nature is the “workshop of all things” (officina omnium, II; IV). Human nature is a medium between animal and angel, a medietas between the earthly and the intelligible worlds. Human nature contains not only elements from the corporeal world but also belongs to the intelligible world: I declare that man consists of one and the same rational soul conjoined to the body in a mysterious manner, and that it is by a certain wonderful and intelligible division that man himself is divided into two parts, in one of which he is created in the image and likeness of the Creator, and participates in no animality ... while in the other he communicates with the animal nature and was produced out of the earth, that is to say, out of the common nature of all things, and is included in the universal genus of animals. (Periphyseon, IV–b) The highest dignity for human nature is that it uniquely mirrors transcendent divine nature. Only of human nature can it be said that it is made in the image and likeness of God. Not even the angels are accorded that honor, so in a sense man is greater than the angels. Human nature may even require the application of affirmative and negative propositions: Man is an animal and man is not an animal (IV). Although, for Eriugena, “rational animal” does not completely define human nature, this mirroring of God in man occurs especially in the cognitive domain. Like Maximus, Eriugena argues that God knows that He is (quia est), but not what He is (quid est). God has existential knowledge, but no circumscribing knowledge of His essence, since, as infinite, He is uncircumscribable: So God does not know of Himself what He is because He is not a “what”, being in everything incomprehensible both to Himself and to every intellect ... But He does not recognize Himself as being something (Se ipsum autem non cognoscit aliquid esse) ... For if He were to recognize Himself in something, He would show that He is not in every respect infinite and incomprehensible. (Periphyseon, II–c) Following Maximus Confessor, Gregory of Nyssa, and Augustine, Eriugena takes the imago dei idea to its ultimate consequence by forging an apophatic-negative anthropology: the human being, as the image of God, knows that it is, but it cannot comprehend or circumscribe its own essence or nature, since, in its deepest core, as imago dei, it too is infinite as God is infinite. All that can be done is to specify the “circumstances” (circumstantiae) which surround his essence, e., place, time, rest, motion, condition, etc., (Periphyseon, II). The human being in this sense is an image of the infinite and uncircumscribable God, and an image is identical to its archetype in all respects “except in respect of subject” (praeter rationem subiecti, Periphyseon II). Any difference between God and human nature is the result not of essence but of “an accident produced by sin” (sed ex delicto accidit, II). Human self-ignorance mirrors the divine self-ignorance; human incomprehensibility mirrors divine incomprehensibility. This makes human nature share in infinity. Eriugena elaborates on the parallels between human and divine nature. Perfect human nature would have possessed the fullest knowledge of its Creator, of itself, and of everything else, had it not sinned (Periphyseon, IV). Man would have ruled the whole of the universe as a king rules his subjects (Periphyseon, IV). Man, like God, is the plenitudo bonorum (Periphyseon, IV). Just as God is unbounded by any category and ultimately indefinable, human nature is ineffable and incomprehensible and open to infinite possibility and perfectibility (Periphyseon, V). God’s transcendence and immanence are reflected in human transcendence and immanence with regard to its world. Consider the following remarkable passage from Book Four which is a typical example of Eriugena’s dialectical thinking and of the close parallelism between human and divine: For just as God is both beyond all things and in all things—for He Who only truly is, is the essence of all things, and while He is whole in all things He does not cease to be whole beyond all things, whole in the world, whole around the world, whole in the sensible creature, whole in the intelligible creature, whole creating the universe, whole created in the universe, whole in the whole of the universe and whole in its parts, since He is both the whole and the part, just as He is neither the whole nor the part—in the same way human nature in its own world (in its own subsistence) in its own universe and in its invisible and visible
parts is whole in itself, and whole in its whole, and whole in its parts, and its parts are whole in themselves and whole in the whole. (Periphyseon, IV–b) Eriugena concludes that human nature is wholly in the wholeness of the whole created nature (in universitate totius conditae naturae tota est), seeing that in it every creature is fashioned, and in it all are linked together (in ipsa copulata), and into it all shall return, and through it must all be saved. (Periphyseon, IV) Eriugena’s cosmological account has been criticized for collapsing the differences between God and creation, leading to a heresy later labeled as pantheism. There is no doubt that Eriugena’s theological intentions are orthodox, but he is a bold, speculative thinker, who believes that philosophy uncovers the true meaning of faith. Eriugena (as does Nicholas of Cusa) gives a unique place to Christ in the outgoing and return of all things. In Christ, the hypostatic union of the divine and the created orders is realized. Christ possesses all the perfections of human nature, since vir autem perfectus est Christus (Periphyseon, IV), and Christ is also one in substance with God. Eriugena recognizes that Christ is unique and that the individual is not collapsed into the universal, even in the return. Humans will always be different from God in that they have been created and God is Creator (Periphyseon, IV). However, a case can also be made for saying that Eriugena really intends his perfected human nature to possess divine attributes in a genuine way. The argument turns on an answer to the following question: To what extent is man made in the image and likeness of God? Eriugena has two answers: an image is not an image unless it is identical to its exemplar in all respects “except number” or “subject” (excepta subiecti ratione, Periphyseon, IV). From this we may conclude that the human being differs from God in subiecto, that is, there is solely a difference in number. But difference in number does not mean that God and man stand apart from each other as two identical billiard balls would occupy different places. Neither God nor man is in space or time; both are incorporeal, and hence numerical difference, or difference in subject, can only have the Neoplatonic meaning that the first will always differ from what comes after the first. God is first, and hence man comes after. But “after” (post) here has no temporal meaning, as Eriugena emphasizes (Periphyseon, IV). A second answer he gives is that God is creator and man is created, but since creation is self-manifestation, that amounts to saying no more than that God manifests himself fully in man. Eriugena sometimes qualifies this by saying that man is by grace (per gratiam) what God is by nature, quoting Maximus Confessor (e., Periphyseon, V–880a), but elsewhere, especially in the concept of theophany or divine manifestation, he fuses the notion of nature with that of grace: all natures are theophanies, divine manifestations, so God is the source of both dona (gifts of grace) and data (what are given in nature), both are revelations of the divine nature. Indeed, there are many places where Eriugena cites texts (e., Maximus) to suggest that God and man mirror each other. His translation of Maximus includes the proposition: “For they say that man and God are paradigms of each other” (Dicunt enim inter se invicem paradigmata Deum et hominem, PL 122: 1220a). One is at the heart of the other. Similarly, human nature and the angelic nature are mutually mirroring. This notion of the intertwining and merging of minds is at the very core of Eriugena’s mysticism and of his understanding of the relation between human and divine natures and their coming together in the person of Christ. Christ is actually what all human beings can become and that is precisely the promise of salvation for Eriugena. Consider the following passage from Book Two: For if Christ Who understands of all things, (Who) indeed is the understanding of all things, really unified all that He assumed, who doubts then that what first took place in the Head and principal Exemplar of the whole of human nature will eventually happen in the whole? (Periphyseon, II) Eriugena articulates the view that God’s becoming human (His incarnation or inhumanisation) is balanced cosmologically by the human being becoming divinized in deification (deificatio, Greek: theosis). The phrase “God was made man so that man could be made God” (Latin: factus est Deus homo, ut homo fieret Deus) is a commonplace among the Christian Fathers, especially in the Eastern tradition. It is to be found in Greek in St. Irenaeus, in St. Athanasius (298–373) in his treatise De incarnatione 54, 3 (PG 25: 192B); and, in Latin, in St. Augustine, (e., his sermon In natali Domini, VIII, PL 38: 1009 footnote; and In natali Domini, XII, PL 39: 1997) and elsewhere. There are several passages where Eriugena (following St. Augustine and Maximus Confessor) balances the humanization/incarnation of God with the deification of man (see for instance his Homilia XXIII, PL 122: 296a–c; Commentarius in Evangelium Iohannis I, xxiv, PL 122: 300a). It is often expressed in terms of man becoming “by grace” (per gratiam) what God is “by nature” (per naturam). Eriugena follows the Greek formulation of the Council of Nicaea (NB: not the Latin version) and the Greek Christian tradition (specifically Maximus Confessor) in occasionally distinguishing between inhumanatio (Greek: enanthropesis)—the relation between the Second Person of the Trinity and human nature)—and incarnatio (Greek: ενσάρκωση)—the temporal becoming flesh of the Verbum in Jesus (see for instance Periphyseon I; and Homilia XIX, PL 122: 294c). Eriugena refers to the theosis or deification of human
Eriugena is an original philosopher who articulates the relation between God and creation in a manner which preserves both divine transcendence and omnipresence. His theory of human nature is rationalist and intellectualist but also apophatic. His theory of place and time as defining structures of the mind anticipates Kant, his dialectical reasoning prefigures Hegel. But above all, Eriugena is a mystic who emphasizes the ultimate unity of human nature and through it of the entire creation with God.
