The Development of Dialectic in Eriugena

Reference to the Logos as developed by Origen, the Cappadocian Fathers, and Maximus, for many if not most just means the development of Neoplatonism, so it is no surprise that John Scotus Eriugena, who specifically takes up the mantle of Origen, Gregory, and Maximus is also read as a Neoplatonist. What may be refused by this insistence, is that Christianity is introducing a new way of thinking, a different logic, or a new order of understanding, which Eriugena will refer to and explain as “dialectics.” It is impossible to correctly read his understanding, and its constructive use of “contradiction,” through a Neoplatonic lens, which has no notion of contradiction as the means of breaking through to a unified understanding, devoid of duality.[1] For Eriugena, dialectic is not simply a mechanism of understanding, but is at once an epistemology and ontology which unifies being and non-being (his “fundamental division”). This is not just more Neoplatonist metaphysics. As Sergei Sushkov, notes, “no matter how attractive a metaphysical schematism might seem to be, it is in fact utterly irrelevant to a dialectically coherent way of thinking of the living whole, and for this reason can hardly be imposed upon Eriugena’s discourse.”[2]

Of course, neither Origen nor Maximus can be reduced to Neoplatonism either, as both are specifically developing an alternative to a Greek metaphysics, while like Eriugena, each deploys Greek resources. Origen identifies Christ as a unique and new order of understanding. “All who believe and are assured that grace and truth came through Jesus Christ, and who know Christ to be the truth, according to his saying, I am the truth, derive the knowledge which leads human beings to live a good and blessed life from no other source than from the very words and teaching of Christ.”[3] Christ is the singular source of this Truth. Origen notes specifically, that his principle is a departure from a Greek understanding and is a turn to Christ as first principle (see my blog on Origen here): “For just as, although many Greeks and barbarians promise the truth, we gave up seeking it from all who claimed it for false opinions after we had come to believe that Christ was the Son of God.”[4] Origen is clearly working within a Christological frame. He is setting forth an alternative world-view, a Christ centered logic, or a Christian metaphysic. The problem is that very few may have been up to the task of following the subtlety of Origen.

Beyond the fact that the name of Eriugena’s major work, Periphyseon, is taken directly from Origen, he is developing Origen’s apokatastasis or the notion of a universal return and divinization. According to Ilaria Ramelli, The noun ἀποκατάστασις, related to the verb ἀποκαθίστημι, “I restore, reintegrate, reconstitute, return,” bears the fundamental meaning of “restoration, reintegration, reconstitution.”[5] She argues that “this doctrine was abundantly received throughout the Patristic era, up to the one who can be regarded as the last of the Fathers: John Eriugena.”[6] She considers Eriugena “to have been the last great Patristic philosopher, whose thought was nourished by the best of Greek Patristics.”[7] There was nothing heretical about apokatastasis. It was deployed by Origen, Gregory, and Eriugena to combat the heresies of the Gnostics, Marcionites, and predestinationists.[8] As she explains, Eriugena is consistent with Origen’s idea “that precisely participation in the three Persons of the Trinity will bring every rational creature to its restoration. For rational beings receive their existence from the Father (who is the Being par excellence and the Good, so that progress toward the Good is also a greater and greater acquisition of being and existence), their rationality from the Son-Logos, and holiness from the Holy Spirit (Princ. 1,3,8).”[9] Book V of the Periphyseon, demonstrates the deep continuity between Origen and Eriugena, as here he deals with the reditus of all beings to God. As Daniel Heide argues, Origen is the greatest ancient advocate of apokatastasis and Eriugena its greatest mediaeval proponent.[10]

Eriugena is also developing Maximus’ picture of Christ being “all in all”, which is thematic for him. Jordan Daniel Wood has laid to rest the notion that participation, in the Greek sense, adequately encompasses Maximus understanding of divinization, and it is Maximus notion (for the most part, along with Augustine) that Eriugena is developing (see my blog on Maximus here). [11] The logic of Origen’s apokatastasis is summed up in Maximus’ formula, “The Word of God, very God, wills that the mystery of his Incarnation be actualized always and in all things” (Ambigua, 7.22). The union of divinity and humanity, the bringing together of the contrary pairs, God/man, or hypostasis, involves a new order of understanding grounded on total identity between God and human. This is not just true in the case of Christ, but according to Maximus, the Christian becomes Christ: “they will be spiritually vivified by their union with the archetype of these true things, and so become living images of Christ, or rather become one with Him through grace (rather than being a mere simulacrum), or even, perhaps, become the Lord Himself, if such an idea is not too onerous for some to bear.”[12] He “draws near to us in his humanity” while bearing the fulness of his divinity, and “having given the whole of Himself, and assuming the whole of man” he witnesses to perfection of humanity and deity “bearing witness within His whole self—by the perfection of the two natures in which He truly exists—to the unchangeable and unalterable condition of both.”[13]

Maximus (and Eriugena) will deploy Origen’s notion of logoi, which makes Christ the ground of the developing dialectic:

The logoi stemming from the Body of Logos will concur anew according to the divine administration in order to form new souls (i.e. the logoi will be ‘embodied’ afresh), in accordance with the Universal Causality which originates in the Body of Logos (i.e. in the will and judgement of Logos) and determines what the new cosmic setting will be for the drama of History (i.e. the dialectical relationship between creaturely and divine will) to take place.[14]

This dialectical exchange is no mere rhetoric, but is descriptive of the taking place of cosmic theosis. Sushkov explains, “According to the dialectical understanding of unity (with a strong appeal to a dialectically coherent treatment of contradiction) that Eriugena does adhere to, the reality of creation cannot be thought of, and therefore known, otherwise than in the way of being inseparable from the universal Principle of all.”[15] The universal principle of the logoi, stemming from the body of Christ, is the ontological ground of this dialectic. As Eriugena claims, “a logical dialectic can lead us to a clear knowledge of spiritual things.”[16]

Eriugena, like Hegel, recognizes that God is in no way excluded from finitude (which would be a form of finitude), but God’s eternality is inclusive of the finite. For Hegel, “God becomes man generically, universally, essentially.”[17] Likewise for Eriugena, “God cannot be known as a finite being, and cannot therefore be thought of by means of predicating attributes of His essence.”[18] Rather, “The infinite is only conceivable by means of contradiction dialectically treated.”[19] Knowing the infinite involves a complete transformation of the mind through which the unity with God restores human integrity, and dialectic pertains to entering this reality. “The combination of dialectic interpreted as a science of being, capable of expressing truths about the sensible world as well as about discourse, with an ontological interpretation of logical concepts allows Eriugena to develop his metaphysical theory, a strong realism.”[20]

One of the examples Eriugena deploys of dialectic contradiction is “man is an animal” and “man is not an animal.” “When taken together in their integrity as the two inseparable aspects of a truly simple (undivided) and therefore really subsisting human nature, in which the inner and the outer cannot be severed, these predicates are to be rightly understood as mutually complementary or, as Eriugena himself puts it, ‘entirely suitable’ (755b).”[21] There is a real contradiction residing in human nature, where man is in one instance bound by an animal state, but he surpasses himself through a dialectical exchange. It is not simply a negation or denial of the body or animality but a revealing or coming to his true nature, in which God Himself is revealed, not through a disconnection but an integration with the flesh. According to Eriugena, “For everything which her Creator primordially created in her” (i.e. human nature) “remains whole and intact, though remaining hidden until now, ‘awaiting the revelation of the sons of God.’”[22] As John puts it, humans were made to be born of God to become “children of God, who were born, not of blood or of the will of the flesh or of the will of man, but of God” (Jn. 1, 12-13). People are to be twice born, of the flesh and the spirit.

Just as Christ is divine and human, so too the apparent duality in human nature – the “contradictory and mutually opposed predicates” taken separately are contradictory but this contradiction describes a potential wholeness so that each is said to be “everywhere a whole in itself.”[23] Humans are both animal and not animal. “This finally means that man’s proper nature can neither be conceived in its truth nor actually affirmed in reality without the negation, which in fact is but the negation of the one-sided finitude of his being, leading to the restoration of its proper wholeness.”[24] “Not animal” must be understood along with “animal” as both true, but neither of which alone captures the fulness of the truth.

The dialectical treatment of the opposition arrives at a new logic: “This is the reality which is embraced by the contraries and is therefore approached when coherently thought of by means of contradiction, aimed at overcoming all dichotomies between the opposites, including the ultimate ones of being and non-being.”[25] This dialectic logic which accords with a dialectic reality enables a restoration of the mind and human nature as a whole, unified with divine reality. The person “becomes at the same time one with the whole of the substantial reality of God’s creation, where the universal contains the particular, and the cause gives rise to the effects, but not vice versa.”[26] The dialectically shaped mind is restored to the reality of the image by which it was created.

Along with other medieval scholastics, Eriugena takes the “image” in Genesis to refer to the natural capacities and the “likeness” to refer to the supernatural endowment, and concludes that through dialectic man is both the image and likeness of God (Gen. 1:26).

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… – in the same way human nature in its own world (in its subsistence) in its own universe and in its visible and invisible parts is whole in itself….[27]

For Eriugena there is not a Neoplatonic hierarchy, but “even the lowest and least valuable part, the body, is according to its own principles whole in the whole man, for the body, in so far as it is truly body, subsists in its own reasons which were made in the beginning of creation; and since human nature is so in itself, it goes beyond its whole.”[28] We are made to “cleave” to God, as Eriugena explains. As the Gospel tells us, “Where I am there is My servant also” (Jn. 12:26).“But He is above all things: above all things therefore is the man who cleaves to Him, and above himself in so far as he is in all things.”[29]

Through a dialectic very similar to that of Hegel, Eriugena pictures how it is that Christ is “all in all” or why “incarnation is creation.” As Sushkov concludes, “All this convinces a careful reader of the Periphyseon that the logic Eriugena is pursuing is all about the transformation of the entire human being (brought about through the cardinal change of the way the mind operates) and bringing it into the substantial reality of creation as it truly is in union with God.”[30] He argues that Eriugena’s dialectic through contradiction, which does not seek a Neoplatonic harmony (a mere difference), marks this new order of logic and reality, through which a true uniformity of subject is realized.

Eriugena’s purpose is not to abolish the Greek logic of non-contradiction, but his aim is to escape the finitude of this thought. Contradiction is not a sign of error but a way of thinking and realizing wholeness spread between being and non-being. “Understood like this, contradiction becomes for the human mind nothing other than an effective instrument of uncovering the infinite nature of things as they genuinely are beyond their one-sided appearance, while belonging to proper (unconfined) being and actually participating in it.”[31] Or the way Eriugena puts it, “Let it then not trouble you that it is said of human nature that it is everywhere a whole in itself, that the Image is whole in the animal, and that the animal is whole in the Image. For everything which her Creator primordially created in her remains whole and intact, though remaining hidden until now, awaiting the revelation of the Sons of God.” Through this dialectic is realized “the unity of substance with Him.”[32]

The Living Letter/Logoi of Creation: The Science of David Bohm as Illustration of the Theology of Maximus

In drawing out the connection between Paul’s positive use of “letter” and Maximus’ development of the term logoi (see here), the material world is inseparably bound-up with meaning. Significance in the Logos is incarnate or embodied and in turn what is embodied has significance. Maximus works out this participatory ontology through his identification of the Logos directly with creation (in the logoi). His is not the Neoplatonic notion of emanation, with its distinction between the One (in whom there is no distinction) and divine Intellect (with its logos and distinction) but in the explanation of Mika Törönen, “This is another kind of simultaneous union and distinction where wholes and parts through God’s providence and judgement make up a harmonious manifold.”[1] The structure of reality, according to Maximus, is in its wholeness through which things are united, but this takes place at both the level of the particular (logoi) and the universal (Logos). In Paul’s terms Christians are the particular instantiation of the letter of Christ, and for Maximus, Christ’s stamp is put upon all creation in the logoi: “‘Who … would not recognize that the one Logos is many logoi distinguished in the undivided difference of created things through their unconfused individuality in relation to each other and themselves?”[2] This accounts for the union between the created and the uncreated but also, according to Maximus, the “union of the mind with the senses, and the union of heaven with earth, and the union of sensible things with the intelligible, and the union of nature with the logos.”[3] The one being made “all in all” or incarnate in all things “lends” the meaning of personhood to all of creation and it is through this incarnate reality that meaning is available (the Logos/logoi relation). This is the primary principle, I would argue, behind Maximus’ theory of logoi and it is the driving presumption (“discovery”) reflected in the theoretical physics of David Bohm.

Theologically the choice is between a theology which divides the Logos and incarnation, so that a preexistent Logos is separated from the incarnate Christ (a logos asarkos or disembodied Christ), or incarnation is understood to be an eternal fact about God in Christ being worked out in and through all of creation. In physics the choice is between a matter and mind duality or, as in quantum theory, the recognition that matter is interdependent with mind and meaning. According to quantum theory, elementary particles account for and respond to the observer, so that mind appears on both sides of observation. In the words of biochemist Rupert Sheldrake, commenting on Bohm, “mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call ‘chance’ when they are made by an electron.”[4]

In most contemporary science reality is presumed to be material or physical, and this is foundational. Matter serves as the final reference, so that the brain may produce consciousness, but this is a by-product of the brain’s activity. A purposeless evolution has produced a material based human activity grounded in the set structures of the physical world. As Sheldrake sums up, in contemporary science everything, including people and animals are reduced to the mechanical and matter is unmixed with consciousness; nature is fixed and unchanging as the total amount of matter is the same and the laws of nature are fixed; all life is based on biological structures carried in genetic material such as DNA; minds are inside heads and are the product of brains; memories are material traces in brains; there is no direct activity between mind and matter (such as found in telepathy); and mechanical or material medication alone is authentic.[5]

Even where this neo-evolutionary doctrine may be denied, the Cartesian split between mind and matter, body and soul, thought and physical reality often prevail, and matter is defined as something that exists independently of mind. A privileging of material reality prevails, even where materialism may not be consciously embraced and even where the existence of mind is acknowledged, it is usually given no place in physical reality. This physicalism reigns, though the emergence of life is mostly unaccounted for (statistically it is improbable if not impossible) and even though science now recognizes that 96% of reality in “dark matter” or “dark energy” is still obscure. Better to believe in infinite parallel universes, all with different laws, then allow for the possibility of a creator God. The prevailing doctrine not only excludes the divine mind, but mind itself – consciousness should not really exist as matter is prime reality. Thus, the materialist philosopher Daniel Dennett can write a book, Consciousness Explained, in which he dismisses consciousness as illusory.

Bad theology guided by materialist assumptions, is actually the historical cause preceding materialism. That is, it was dualistic Christians who first separated mind from matter. As Sheldrake explains, “They downgraded matter, making it totally inanimate and mechanical, and at the same time upgraded human minds making them completely different from unconscious matter.”[6] They assumed they were strengthening arguments for the soul (mind), empowering it over the body (as in Descartes), and they sought to show the superiority of humans over animals. Humans, they would argue, are immortal, completely separate from animals (in their possession of mind and soul), and in the process, they created an unbridgeable gulf between body and soul and between humans and “nature.” Most people, Christian or not, presume this dualism, in spite of its deeply unchristian bias and regardless of the fact that modern physics indicates the fallacy of the materialist worldview.

Bohm (1917-1992), a theoretical physicist who studied under Robert Oppenheimer, has boldly set-forth for an alternative understanding. He argues that quantum physics, due to its interactions with the mind of the observer, spelled the end of both materialism and Cartesian dualism. Mind is not localized in the head of the observer but extends into the world, so that thought shows itself in and through material reality. Human minds can reach to the stars because the world resonates with and can be read and touched by thought and at the same time,  the world seems to look back.  

Bohm’s interpretation overlaps with Maximus’ understanding of logoi, in that the world is penetrated by mind. The materialistic tendency is to separate the physical and mental, or soul (mind, meaning) and body so that the “psychosomatic” is thought to refer to two distinct entities, with “psyche” or mind arising as a result of the material body (soma). Bohm maintains there is a unity between soma (the physical) and significance (the mental) as they are part of “one overall indivisible reality.” [7] The observer is part of the observation, and in turn the observed accounts for and responds to the observation. Like Logos and logoi or creation and incarnation, each “reflects and implies the other (so that the other shows in it) . . . they are both revealing the one unbroken whole of reality, as it were from two sides.”[8]

The letter written in stone or ink does not have its meaning in the medium, and so too in the physical world, DNA or electrical and chemical activity, are not reducible to their medium. A television signal is produced by images from a camera transformed into subtle electrical signals, carried on even more subtle radio waves, but the content is not found in electricity or radio waves per se, but in the images and sound in the television set received by the mind of the viewer.  According to Bohm, “Meanings are thus seen to be capable of being organized into ever more subtle and comprehensive overall structures that imply, contain, and enfold each other, in ways that are capable of indefinite extension.”[9] The depth of subtlety and the extent of their manifestation is infinite.

Meaning is not fixed, and as a result there is an openness toward infinite clarification, deeper understanding, ongoing discrepancies, which all point to a depth of structure or an ever-changing understanding and more comprehensive meaning.[10]   For example, Newton’s laws indicated Einstein’s insights of a conjoined space/time, which indicate a quantum reality. Bohm explains this involves a paradoxical unfolding: “while the quantum theory contradicts the previously existent classical theory, it does not explain basic concepts of this theory as an approximation or as a simplification of itself. Rather, it has to presuppose the classical concepts at the same time that it has to contradict them.”[11] It is not that quantum theory introduces new basic concepts, but it introduces ambiguity into concepts such as position and momentum, which were previously unambiguous. The ambiguity is not simply in the mind of the observer, but there is an ambiguity (openness) built into basic reality.

Matter is open to mindful interaction, which means the world can act back upon us, positively or negatively. In cancerous cells there is replication and duplication, or in neurosis the compulsion to repeat, a sort of miscommunication which damages the body or mind, creating a closed feed-back loop. Misinformation or disinformation is a disease or neurosis that directly impacts the host. “It is evident that this typical form of a runaway feedback loop between the soma- significant and the signa- somatic is deeply involved in a wide range of neurotic disorders.”[12]

The letter kills, or meaning takes on a deadly form precisely because it is stunted and turns in on itself. A deadly relationship to the law (occurring between meaning and embodiment) may infect one individual, interpersonal relations, or relationships with nature, as all involve soma-significance. There may be either a circular feedback which gets stuck in a deadly loop or soma-significance extended and opened to ever-renewed growth. Relationships with Nature or with the Cosmos are affected, on both sides of the relationship, by a meaning that may be rightly or wrongly construed. That is, just as in human relationships there are two sides interacting and affecting the relationship, so too the world in general reflects this interactive relation. “Indeed, insofar as we know it, are aware of it, and can act in it, the whole of Nature, including our civilization which has evolved from Nature and is still a part of Nature, is one movement that is both soma- significant and signa- somatic.”[13]

There is no flat material world, or in Paul’s language, the letter that kills is deceptive and deadly, not because it is a reality, but because it is presumed to be an end in itself. The law, Scripture, or the letter, which is presumed to be a foundation is on the order of a materialism that assigns the fulness of reality to the material order. It is deadly in its finitude, deceptively hiding the eternal. On the other hand, the living letter has the breath and breadth of personhood and access to participation in or even identification with Christ. The letter is part of a word which is part of a structure of meaning but this meaning always exceeds itself in the manner of personhood, not simply referring back to the material or to other letters but resonating with the eternal – an excess of meaning without a definitive closure. As in Maximus, the many logoi have their union in the Logos, containing both a distinct and unconfused particularity with an integrity in the unifying Logos.

There is the continual encounter with Christ in creation, or the filling out of the Logos in the logoi, which may simply specify the mind in Bohm’s description. The name of the universal in the particular, or the union of body and meaning, is specified in the logoi of the Logos. The extension of the incarnation into all creation, is a reality about creation reflected in quantum physics, which is simultaneously sensible and intelligible. There is a singular unbroken reality, which apart from the specificity of the Logos tends to be divided and delimited (the letter that kills). The isolated letter, law, or material nature cut-off from its extended meaning is reductive but the letter or quantum reality as a living process refers to the personal, mindful, eternal, interpenetrating all things.
