High Middle Ages
Late Middle Ages
“Medieval”: “Medieval:” The term “medieval” was coined around 1469 by Giovanni Andrea, the Italian humanist and librarian for the Pope, from the Latin medium aevum, “middle age.” From its invention, the name carried a derogatory tone for something primitive or out of date to differentiate 15th c. modernity, the humanists’ rebirth (renascentia) of the better, illustrious and glowing ancient Greek and Roman culture, from the “middle” or intervening “dark ages,” the gloomy years of barbarism.
When? As the “middle age,” Medieval Philosophy stretches from the end of the Roman Empire to the rise of the Renaissance, roughly the 5th to the 15th centuries (although its currents begin in late antique philosophy, post Aristotle’s death (322 b.c.e.), and persist into modern philosophy to the late 17th c.).
Where? Its intellectual loci were Athens, Rome, Paris, and Alexandria; but significant sites included London, Canterbury, Oxford, Hippo, Carthage, Jerusalem, Constantinople, Chalcaedon, Naples, Ravenna, Florence, Louvain, Cologne, etc.. “Where” is easier to conceive by ideological regions: those lands that became Christian, Jewish, and Islamic, spreading across Europe, North Africa, the Middle East, and Western Asia.
What? In essence, it is a stew of Platonic-Neoplatonic and Aristotelian-Peripatetic philosophies intellectually synthesized and heavily seasoned with esoteric thought (esp. Hermeticism, Gnosticism, and philosophical commentary born from Chaldaean Oracles[1]), and then molded to an Abrahamic monotheistic conceptual framework. Medieval philosophy is primarily religious thought, but such necessitates examination of everything: cosmological and teleological (origin/structures of universe, physics, causes, ends), logical and epistemological (argumentation, grammar/linguistics, knowledge’s possibility/limits), metaphysical and ontological (being, reality, human nature, self/other), ethical, social/political, and aesthetic (art, perceptions).
Key Ideas / Theories that Surface Regularly:
Neoplatonism: Neoplatonism (New-Platonism) establishes a mystical interpretation of Plato as a base for further philosophical work; it was the predominate influence for Abrahamic philosophy until the mid to late middle ages. It relies upon Plato’s Timaeus, Parmenides, and unwritten doctrines (purportedly most discussed). Plato’s nephew, Speusippus (ca. 407-339 b.c.e.), the first diadochus (head successor) for the Academy, codified these teachings into that on what would become the focus of the middle ages; their basis is in Pythagorean theory and expound first principles of the cosmos as the Monad and Dyad (the One above Intellect, beyond being, and the Many); equally important is World-Soul, similar to Plato’s Demiurge, who mediated the ideal and matter to create the elements, which expands the dualism into a tripartite metaphysical system. In essence: there is first the Monad over against the infinite Dyad from which all multiplicity comes; this dichotomy produces Number, “by reason of a certain persuasive necessity,” in order to provide the “principle of infinite divisibility,” which operates by an elaborate geometry to then create all that is.[2] Within multiplicity’s realm of World-Soul, Speusippus claims that goodness become apparent.[3] The good is a creative power, a demiurgic activity of the World-Soul and echoes the Timaeus’ characterization of the goodness of the Demiurge as the “agent of all order and tendency towards perfection in the physical universe. …”[4] The creative infusion of goodness through a tripartite system gives medievals their ground from which to conceptualize variant renderings of hierarchy and agency. Neoplatonism’s cosmology gives, then, the basis to create structures (of meaning, for the sciences, of nature, people, etc.), which allows a narrative plot for ethical, social, political, religious, and aesthetic theories.
Three Conceptions of Soul: The following charts demonstrate three Conceptions of Soul: Plato’s, Aristotle’s, and Aquinas’. All three are tripartite models; their fundamental divisions remain fairly similar while their conception changes from a more mythic explanation to biological characterization. However, the philosophical import to attend to here can be grasped by thinking these three conceptions in relation to Augustine as a preeminent example of Neoplatonism’s synthetic nature. Augustine is Platonist on most matters, but his idea of soul is closest to Aristotle’s and became the model further elaborated by Aquinas, and therefore the canonical exemplar of the Christian conception of soul. Augustine is therefore himself a model of Neoplatonism in the sense of synthesizing diverse inheritances (Platonic and Aristotelian) with developed commitments (Christianity) and bequeathing it to later generations (Aquinas) and thus to Christian dogma and tradition and thereby as the presumptive model for Western (scientific, psychological, spiritual) belief systems. Plato’s Soul: Soul and Body are of two distinct natures (mostly accords with Augustine’s version of soul). Soul is distinct from, not unique to, the mortal body (mostly vs. Augustine’s version of soul, which is personal). Soul is immortal; however, details of the where and how as are ambiguous, e.g., Apology’s two proposals for after bodily death (like an eternal sleep and transmigration of soul to realm where Socrates could interrogate all past heroes) leave questions (sleep: just body, or soul, too, and if soul is distinct, while body sleeps in ground, where does the soul ‘sleep’?; and other realm: either soul is self, and thus personal, yet not same as body, and thus a collective of bodiless selves hang out in this other realm, or else it suggests contradiction of soul’s distinction), and further questions arise comparing these ideas to Republic’s ‘myth of Er’ and Phaedrus’ account of self which suggest a truer transmigration of souls so that who/what one is is determined by who/how one was in one’s previous incarnation. In Phaedo, Socrates proposes at least four arguments affirming soul’s immortality and that its afterlife is a contemplation of truths, although it is uncontroversial to say that the arguments do the opposite of squashing all skepticism. (Both accordances and contradictions to Augustine’s version.)
Rational (Highest) part of Soul Concerns Logos, Reason and Speech Illustrated metaphorically, e.g., in Phaedrus as Charioteer; in Republic: Guardians
Spirited (Middle) Part of Soul Concerns Ethos, Behavior (emotive & moral) E.g., The Noble Horse / Soldiers
Appetitive (Lowest) Part of Soul Concerns Eros, Desires E.g., The Ignoble Horse / Craftspeople Aristotle’s Soul:Three Definitions of Soul: 1. “…the soul must be a substance in the sense of the form of a natural body having life potentially within it” (De Anima, 412a20-1). 2. “The soul is the first actuality of a natural body that is potentially alive” (De Anima, 412a27). 3. “[Soul is] an actuality of the first kind of a natural organized body” (De Anima, 412b4-5).
Rational: exercises all lower powers of soul plus Nous (mind, understanding, or active intellect and passive intellect): Found only in Humans, who also have Sensitive and Nutritive parts. Rational
Sensitive: exercises (1) sense-perception, (2) desire, and (3) locomotion {imagination and memory follow here}: Found in Humans and in Animals /Brutes, who also have Nutritive part. In Between Rational & Non-Rational
Vegetative/Nutritive: governs growth and reproduction: Found alone in Plants, but presupposed in the higher levels of soul. Non-Rational
Aristotle’s soul is the form of the body (i.e., think soul-body : form-matter); intimately related to the body, so likely inseparable, hence may die when the body dies, or, at least, all but Nous will die with the body, freeing Nous back to the unknown. (Augustine’s version is most like Aristotle’s, but he makes it separable from the body so it can be immortal, wholly personal. Augustine also uses Aristotle’s language to name and describe the soul, however makes it more ethically-relevant like Plato.)
St. Thomas Aquinas’ Soul: (development from Augustine’s, and representative of Aristotelian-Christian schema of soul)
Vegetative Level of Life Nutrition Growth Reproduction
Human as union of body and rational soul
Sensitive Level of Life Exterior senses (sight, hearing, taste, touch, smell) Interior senses (Sensus Communis, Imagination, Vis aestimativa, Memory) Locomotion Sensitive appetite
Rational Level of Life Active Intellect Passive Intellect Will
Aquinas’ soul is similar to Aristotle’s except that while the body and soul are united in one, the soul is immortal.
Mysticism: Mysticism: immediate, direct, intuitive knowledge of God or ultimate reality attained through personal religious experience, which may be complete return or via a single or series of brief encounters, dreams, or visions whose continuum of contact proportionate to received knowledge (from indubitable to scant, veiled). Etymology: Greek mysterion (“secret rite or doctrine”) from mýstēs (“one who has been initiated”) from verb mýein (“to close” or “to shut,” i.e., closing of the lips so as to keep a secret, shutting of the eyes because only the initiated allowed at sacred rites, hence its enigmatic ‘knowledge’ neither had as reason or normal sense data).
Mystical Methods of Naming (Knowing): Cataphatic Theology: (affirmative theo) ascription of confirmatory names to God w/o equivocation: God is Light.
Apophatic Theology: (negative theology) ascription of negative names to God or negation of the possibility of affirmative names: God is not Light.
Why?: One seeks to know that something is, what it is, how it is, and why it is; establishing ‘that’ is to establish a name, which then gives insight to ‘what’, from which to induce/deduce ‘how’ and ‘why’ (supported by Emanation Theory). The greatest epistemic challenge is God, who is “nameless and yet has the names of everything that is,” and, “Since the unknowing of what is beyond being is something above and beyond speech, mind, or being itself, one should ascribe to it an understanding beyond being,” hence the focus on naming (Pseudo-Dionysius, Divine Names, 596C, 588A).
Theory of Emanation: Etymology: emanation: “to flow forth or stream;” indicates how causality divinely pours forth; visualized as streams, bubbling water, fountains, cycle of clouds producing rain evaporating back into clouds.
Iamblichus: “ever-flowing and unfailing creativity;” Proclus: “Every effect remains in its cause, proceeds from it, and returns to it;” Damascius: effect “flowing” from its cause; Pseudo-Dionysius: Cherubim as “effusion of wisdom,” God and His attributes as “outpouring” to His creatures, God’s creativity as “bubbling over” and “bubbling forth;” Romans 11:36: “From him and to him are all things.”[5]
History: ancient (pre-Presocratic) Egyptian roots, flourished in pagan Neoplatonism (ca. 204 c.e. (Plotinus’ birth)-529 c.e. (Justinian’s closure of Plato’s Academy)), adopted by Abrahamic traditions.
First principle: all derived things (the dyad, the many) proceed out of an originary source (the monad).
Theory: everything that is (dyad), before it is (before creation), is the One (monad); the One creates by “procession,” an overflowing; the overflow is creation, which, by nature is the one-become-many, hence by nature seeks “reversion,” a return to the One; the procession-reversion cycle is driven by desire:
“Because it [God/The One] is there the world has come to be and exists. All things long for it. The intelligent and rational long for it by way of knowledge, the lower strata by way of perception, the remainder by way of the stirrings of being alive and in whatever fashion befits their condition” (DN 593D).
Philosophically Yields: a metaphysics: Cosmology (account of universe’s origin, power/activity of creation); ontology (gives account of being: everything that is, is of the One); epistemology (gives a way to understand creation & creator by knowing dyad as of the monad); teleology (gives end (purpose, goal): return to the One); ethic (gives duty: make self worthy of return via rational exercise/spiritual practice).
Abrahamic Instantiation: emanation as creation infinitely expands the idea of Adam as “created in His image” (Genesis 1:27) to say everything is created in His image, as His image, by His image, and will end in His image with a return to Him. Piety dictates mental and lived pursuit of God.
Emanation’s Mereological Questions on Hypostasis and Subsistence:
Mereology: the study of wholes and parts, of the one and the many. e.g.: is a human a whole (an essential oneness), or a compositions of parts (collective of attributes, e.g., rational + animal + boned & skinned thing + eye-having + gendered + etc.)? If it is a whole, it must have a discernable unity that is not a mere attribute; if it is a composition, some attributes could define it more essentially than others (e.g., can you be human, but not rational, or human, but without limbs?).
Hypostasis: “underlying state/substance” (translations of the Greek as “substance,” “subsistence,” “that which exists of itself,” are misleading because hypostasis is neither material nor an individual thing); designates something’s fundamental reality, i.e., the X qua X that survives accidental change, e.g., the human-ness of a human unchanged if one’s dress is red or blue, if one is healthy or sick, etc..
Subsistence: translation of “hypostasis” only sometimes & somewhat synonymous: the unity in which a something shares (e.g., the human-ness of humans, not the many different humans as all human).
Emanation’s Mereological Challenge: God is everything and is not everything at once (because what everything is is God (from, by, & of), but God is neither any one part, nor a mere collection of parts, because He is pure simplicity, unity, and oneness).
Christian Examples of this same Mereological Challenge: God as Trinity (three and one at the same time) and Monophysiticism vs. Chalcedonian Christology (monophysiticism (monos- “one, alone;” -physis, “nature”) argues Jesus has only one nature (his humanity is a part of his divinity), eventually deemed heretical; Chalcedonian definition (ca. 451 c.e. Council of Chalcedon) argues Jesus has two natures (humanity distinct from his divinity), caused Church schism, eventually and mostly deemed orthodox by the Western and Eastern Churches).
Earliest explicit source of Subsistence Debates: Proclus’ Elements of Theology:[6] 211 propositions and proofs tracing origin in the One (to Hen) to the instantiation of the Many individual souls in the world through a chain of henads, individuated ones that overflow from the one and carry multiplicity, eventually, to the many through principles of apeiron and peras, the infinite and the limit, which proceed to the Nous, intellect, and then to the Psuche, soul, and finally to the material world (Christianization of this polytheistic system alters the chain so Mind are angels, Soul are humans). This text bears influence of Presocratics (e.g., Pythagoras most known for elaboration of aperion and peras, hence, likely having Pre-Presocratic roots) and was later summarized and attributed to Aristotle as Discourse on the Pure Good (predominately in Arabic) and Book of Causes (Liber de Causis), and had great influence when Neoplatonism waned and Aristotle rediscovered; Thomas Aquinas first notably realized that the Liber de Causis was a summation of Elements of Theology. It is also the book Pseudo-Dionysius attributes to his [likely-fictionalized] teacher, Hierotheus (cf., DN 648A-C).
Ecstasy: Ecstasy: Ekstasis, trance, distraction; from ex- “out” and -stasis “standing,” thus, a standing outside of oneself (existanai phrenon “to drive out of one’s mind”); opposite is enstasis, standing within, interiorized contemplation.
Neoplatonism frequently depicts emanation as ecstasy: procession is God’s standing outside of himself, an ecstatic outpouring of God as creation; reversion is creation’s standing outside of itself so as to return to One.
In Proclus: potency (power of One as Creator to create and the creating) is ecstasy as procession from unity to creation and creation’s return to the One; hence: emanation as ecstasy as (power of) causality.
In Pseudo-Dionysius: emanation as ecstasy in creation and return, but also as a means and goal of return: naming is our function as participation in emanation, our purification by participation, and that which drives us outside of ourselves (beyond reason & materiality) so as to return to God in union.
Ecstasy intimately connected to love as entering a trance, a spiritual communion, with the divine.
In the Canon: Saint Aquinas’Treatise on the Passions [Treatise on Human Acts] cites P-D’s authority that ecstasy is produced by divine love and God suffers ecstasy through His love, but then moderates P-D’s version:
Ecstasy as affliction of power of apprehension: ecstasy when placed outside of one’s proper knowledge is an experience wherein one is raised up (by another) to a higher level of knowledge. This named an “indirect love,” wherein one dwells in contemplation upon another and has mind lifted upward.
Ecstasy as affliction of power of appetite: ecstasy when debased, overcome by passion or madness, is a defilement. Named “direct love” between two people, be it agape (friendship) or eros (erotic love), wherein one is carried outside of oneself, but returns to self with desire for possession, a circling that is not true and full ecstasy.
Johannes Scotus Eriugena (ca. 815-877, Irish Neoplatonist philosopher, Latin translator of P-D’s corpus), explains ecstasy and the ecstatic power of love (re: Song of Songs): “Love [dilectio] surpasses knowledge, and is greater than intelligence. He [the beloved] is loved more than understood, and love enters and approaches where knowledge stays outside” (Periphyseon 175, 1038D). As with P-D, love lets us ‘know’ what we cannot.
Rabbi Dor Baer (1704-1772, Talmudic and Cabala scholar) described experience of ecstasy as a “going out of Egypt,” re: ancient Hebrew’s “Egypt” identical to “limitations,” hence, literally and theoretically a pilgrimaging out of or away from one’s home, a movement beyond one’s limitations.
Jean-François Lyotard (1924-1998, French postmodernist) employs ecstasy aesthetically as a sensation of being (or experience pulling us) outside of ourselves that provides possibility for figuring, thinking, speaking of, or testifying about that which is deemed impossible by empirical reality or logic.
Historical-Philosophical Sketch:
The Medieval period is typically divided by Medievalists in three parts: Early Middle Ages (476-1000), High Middle Ages (1000-1300), and Late Middle Ages (ca. 1300-1453). To make the divisions a bit more revelatory in general, there is a brief time-line below, then, to show more how these divisions are revelatory for philosophy, I think the following historical survey is important.

Philosophical-Historical Sketch:
Cusp between Late Antiquity-Early Middle Ages (ca. 400 b.c.e-400 c.e.): Why these dates? The start is around when Speusippus, Plato’s nephew, was heading the Academy and codified selections and interpretations of Plato into the ground of Neoplatonism that would become the focus of the Middle Ages; this range includes the earliest Patristic (Church Father) philosophers (1st-6th c. c.e.) and the rule by Constantine (324), the first Christian emperor, which ensured the socio-political support of the former; and keeps philosophers like Augustine (354-430) and Boethius (475-524/5/6) from being classified as just ‘ancient,’ when they are clearly of a new breed.
Historically:The Roman Empire: The Hellenistic Period: Roughly between Aristotle (post-322 b.c.e) and Boethius (pre-480 c.e.). Around the 1st c. b.c.e., the Roman Empire technically came to be an empire in the sense of being ruled by emperors, although the growth of the Roman Republic had been happening since the 6th c. b.c.e., most notably when and due to the 4th c. b.c.e.’s Alexander the Great (ca. 356-323 b.c.e.) leading the Greek armies against the Persian Empire and established Greek Kingdoms throughout Egypt, Palestine, Syria, and Asia Minor. The Greeks called themselves “Hellenes,” thus the name we call the period by: the Hellenistic. This period was Greek, but distinct from Classical Greek culture; Greek was a second language for most new-Hellenes, and Alexandria became a new locus of Greek education and culture, especially for science, mathematics, medicine, and philosophy, while Athens remained an educational and cultural center for philosophy and rhetoric. During this time, educated Romans knew Greek and exerted much energy (especially Cicero, Lucretius, and Seneca) translating and commenting on Greek philosophy in Latin, while many other thinkers simply wrote still in Greek (e.g., Epictetus, Plutarch, Marcus Aurelius, and Plotinus). The turbulent transition from the prior to common era saw Julius Caesar fall, the rise of Mark Antony and Octavian, the latter defeating the former and Cleopatra, and hence becoming Augustus and ensuring more political stability and flourishing through many successions (for the most part, some bumps, e.g., Nero, some heights, e.g., Hadrian, Marcus Aurelius) to Commodus around 180 c.e.,, which many mark as its height and beginning of the decline.
Philosophically: The Patristic (Church Fathers) Philosophers (1st c. ff.): Christian philosophers: a minority within the minority of monotheistic philosophers. New Testament doctrines were unexplained, theological concepts undeveloped, responses to pagan arguments unformed. Most early patristic philosophy consisted in defenses of its religious principles using Platonism-Neoplatonism and some support from Aristotle, Stoics, Materialists, and esoteric doctrines. Key issues: relation of Scripture and Greek (i.e. pagan) philosophy and the interplay between faith and reason.
Historically:The Two “Roman Empires:” The empire was too large to be singularly controlled, extending as it did from England to North Africa to Syria, its eastern half speaking Greek, its western half speaking Latin. Many regions were invaded or infiltrated by outsiders, the “barbarians” of the Goths, Vandals, Huns, Franks, etc. The Emperor Diocletian divided the empire in 286 c.e. into two halves: the Eastern and Western [some histories attribute the split to Constantine and others to the death of Emperor Theodosius I in 395], thus, the middle ages had two “Roman Empires” beginning from the 3rd c., the Eastern one in Constantinople (Greek Orthodox) and another in the West declared by Rome and eventually housed in Germany (Latin Catholic).
The Eastern Roman Empire: The Byzantine Empire:
The Byzantine Empire was founded in Late Antiquity by Constantine, who became emperor in 324 c.e., and was the first Christian emperor. In 330, he moved the capital of the Roman Empire from Nicomedia to Byzantium, and it became called New Rome or Constantinople (this new empire is distinguished from the Ancient Roman Empire in several ways, from language to religion to culture). Emperor Heraclius formalized the division of the empires by reforming its administration, army, and declaring Greek the official language. The Eastern, Byzantium empire lasted until about 1453, and was powerful economically, culturally, and militarily, despite several periods of suffering, notably by Turkish invasions (ca. 1071) and the Fourth Crusade (1204), which left it dissolved into different Greek and Latin regions or states, and numerous civil wars (14th c.), which eventually led to the Fall of Constantinople and the conquest of remaining territories by the Ottoman Empire (15th c.).
The Western Roman Empire:
The Western Roman empire existed intermittently between the 3rd and 5th c.. In 410 c.e. came the first major and successful attack on Rome by the Visigoths; they starved Rome for two years before being invited in, the starving citizens preferring servitude to continued starvation. They raided and plundered the city, but found no food, thus after making the streets run in blood and architectural wonders go up in flame, most of the Goths moved on to other cities, eventually settling in Gaul. Following, were numerous invasion by outsiders, including the Vandals and Huns. The Western Roman Empire ended officially in 476 c.e., when the Goths deposed Romulus Augustulus, the last de facto Western Roman emperor [this date is sometimes offered as the end of the Roman empire and the birth of the Middle Ages proper]. After this time, the former empire’s grandeur disintegrated into lawlessness, in “darkness.” Over the next centuries, populations decreased all over, illiteracy spread, as did disease and poverty. The architectural wonders fell into ruins, people scavenged them for building materials. The world was in a disintegration. The very slow ignition of unity came not from a new emperor, but from missionaries and monks with the spread of Christianity. [The Western Roman Empire was reputedly re-founded as the Holy Roman Empire, although the latter was German and contained little of the same territory.]
Philosophically: 4th-5th Centuries: The Council of Nicea (325) concretized Church views on Trinity; legitimacy and clarification of Church position aided the philosophical undertaking. Important 4th c. Greek Philosophers: Eusebius, Gregory of Nazianz, Basil the Great, Nemesius, and, most importantly, Gregory of Nyssa—who undertook the first rational argumentation for all the teachings of the Church (including its mysteries), his Platonism emphasized purification of human soul and humanity’s return to God (deeply influenced 9th c. John Scotus Eriugena and 12th c. Bernard of Clairvaux). Important 4th -5th c. Latin philosophers: Marius Victorinus, Ambrose, and especially Augustine, whose conjunction of Neoplatonism (via Plotinus, Porphyry, Victorinus) with rhetoric (via Virgil, Cicero) and Christian thought (via his mother, St. Ambrose, Scripture) epitomizes the century’s philosophical spirit, and Boethius. The most notable 5th c. Greek-inspired Christian philosopher is Pseudo-Dionysius (coined “mysticism,” profoundly influenced later medievals Eriugena, Hugh of St. Victor, Robert Grosseteste, Albertus Magnus, Bonaventure, and Aquinas).
Augustine (354-430 c.e.):
Saint Augustine of Hippo’s life is itself a work of art, recorded in critical detail by his own hand in his Confessions: his autobiographical exploration of his anxiety-ridden conversions (broadly including the conversion from infancy to adulthood, educationally from a reluctant student to a scholar, intellectually to philosophy and theology, and spiritually and religiously he converts from skepticism to Manichaeism and to Christianity). His biography accounts for some of his intellectual influence: his Greek and Roman education, his Manichaeism, his exposure to skepticism and Neoplatonism, and his Christian exposure and study. More specifically, we can argue that Augustine was firmly intellectually formed by the conjunction of Neoplatonism (through Plotinus, likely through Porphyry and Victorinus), with rhetoric (through Virgil and Cicero), with Christian thought (through his mother, Saint Ambrose, and the Scriptures), to which we can conclude that he as much embodies the merger of pagan Neoplatonism with Christian thought. St. Aquinas wrote of him: “Whenever Augustine, who was saturated with the teachings of the Platonists, found in their writings anything consistent with the faith, he adopted it; and whatever he found contrary to the faith, he amended.” These Platonic currents in his thought can be seen throughout his works. Notable examples in his work On Free Choice of the Will include the stylistic form of the work as a dialogue and his methodological and pedagogical relation he demonstrates to his student Evodius. Further, in its content, the Greek influence can be seen in his relation of faith and reason wherein the former is required as a foundation but the latter is of the utmost importance. Augustine, like Plato, privileged non-dogmatic reason; Plato and Augustine both held that the highest truth was a grasp on the form of the good, only diverging insofar as Augustine’s interpretation of the good is either God. While the forms, as either the Good itself or God, may be universal, knowable truths, this does not mean we have perfect knowledge of them.
Boethius (ca. 475-524/5/6):
Roman born, into important family which included emperors and counsels; thought to have been born into a Christian family, with some scholarly debate on his religiosity and whether he abandoned it for paganism; he was well educated and fluent in Greek; his education led to his hire by King Theodoric the Great, he became a senator by 25 and counsel to the kingdom of the Ostrogoths, then, in 522, appointed magister officiorum, the head of government and court services; one of his notable works was towards trying to reestablish relations between the Churches in Rome and Constantinople, this may have led to his disfavor; in 522, imprisoned and later executed by Theodoric for suspicion of conspiring with the Eastern Empire for his defense of another ex-counsel; while imprisoned, he wrote his famous Consolation of Philosophy; his whole oeuvre was concerned with the preservation of ancient wisdom, especially philosophy; he had intended to translate all of Aristotle and Plato into Latin, but completed only some (but his translation of Aristotle’s works on logic were the only significant pieces of Aristotle available in Europe until the 12th c.); many of his own commentaries were lost, but, in addition to Consolations, his works on Music, the Trinity, and Theological Tractates, and Institution Arithmetica survive.
Pseudo-Dionysius (ca. 471-512/518):
Writing about the power of names, yet, we do not know his real name, we believe Pseudo-Dionysius to have been a Neo-Platonist Christian writing in Syria sometime between 471-512/518 C.E. He adopted the name of Dionysius or Dion (the) Areopagite, who was the distinguished convert of St. Paul from the Acts 22:17 ff.
Pseudo-Dionysius wrote a number of works including Letters, which are predominately exegeses of his thought and moral advice and four surviving treatises: The Celestial Hierarchy delineates the ranks of angels; The Ecclesiastical Hierarchy delineates the ranks of religious figures; The Divine Names studies the intelligible names applied to God (i.e., Goodness, Wisdom, Yearning); The Mystical Theology coins “mysticism” and philosophically promotes abandonment of the sensible and intelligible to experience divine union. Two non-existent treatises, possibly never written, are: Theological Representations (Outlines of Divinity), said to be on the trinity and incarnation, and the Symbolic Theology, which reputedly analyzed the sensible names representing God (i.e. Rock, Right Hand). Pseudo-Dionysius’ work had a great influence, even when his identity and authority began to be questioned and challenged and even after he was declared blasphemous, then accepted as orthodox. Perhaps most impressive is The Divine Names, which synthesizes cataphatic and apophatic theologies to know something of God and enact a spiritual exercise so as to achieve union.
Early Middle Ages (400-1000): The fall of the Western Roman Empire (476) marks the typical start of the Middle Ages, but more formative is Constantine’s Eastern Empire’s rise and land reconquer: made history bloody and bleak, but his holy war spread Christianity everywhere, hence, spread the need for philosophy. With Mohammed’s death (632), Christian-Islam battles began, but Islam’s domination of Middle East and Spain, initiated vast translation projects between Arabic, Persian, Hebrew, Greek, and Latin texts. More massive bloodshed vs. Moors gave rise to Charlemagne, Louis the Pious, & Carolingian Renaissance, benefitting philosophy by establishing schools, inventing Trivium/Quadrivium curricular structure, promoting literacy via reformation of Roman alphabet/Latin script, resulting in massive translation of philosophy into Latin. More bloodshed vs. Vikings wore down everything, leaving most of the 800-900’s with more blood than thought.
Historically: Rise of Christianity & Re-Conquest by the Eastern Empire of the Western: This period is remarkable for its rise and spread of Christianity. In the Western part of the empire, amidst harsh living conditions and no sense of security, Christianity proved the only thread of unity amongst people otherwise divided and quickly combative. It also promised people who lived in constant wariness a hope of everlasting peace.
Constantine, in the East, converted to Christianity, which led many to follow suit. Including Clovis (d.511), in the West, the Barbarian King of the Franks, who converted and used Christianity as a way of converting the people whose territories he took over (then called the Merovingian Dynasty). Christianity also provided him an excuse for his constant invasion: holy war.
In 533 c.e., from Constantinople [Eastern/Byzantine Empire], Roman armies led by Emperor Justinian I (483-565, ruled 527-565) pushed west to reclaim their former lands. The Byzantium warriors from Constantinople surge west to Rome, reconquering lands, leaving immense bloodshed in its wake. His reign saw the rewriting of Roman law, a revival of Byzantine culture, and much building, including the greatest cathedral in Constantinople. He was largely, albeit temporarily successful in his reunion of the Empire. By 542 c.e., his armies had reclaimed most of the Mediterranean, however, at the same time came the bubonic plague. The disease was fierce and deadly. The plague infected one half of the population of Constantinople (it is approximated that 100 million were killed), including the emperor (but, he survived, no matter how scarred both physically and mentally, the disease making him even more ruthless). Following the plague came starvation and a general halting of all work and everyday activity. In 542 the plague mostly died (future centuries had further bouts), but it took centuries to rebuild and repopulate. With the death of Justinian I, the empire could not continue to sustain the lands they had recaptured. The troops began to withdraw, bringing back a deeper darkness to start the 7th c.
Trade ceased, architectural innovation ceased, education was nil, the populations were sparse, culture was sparser. Myth and superstition took over. The Catholic Church condemned these stories, but the villagers paid little heed. Most of life was misery; half of all children died; most children who lived lost at least one parent before they became adults. The only unity at this time was found in the Church; the Churches were the only centers of commerce, light, and diversion.
Without the monks, we would have had almost no ancient works preserved. There was no real education or literacy outside of the clergy and books were being burned constantly when labeled as heretical. Jews in Alexandria were translating the Jewish Scriptures into Greek, and the New Testament was written in Greek, as well. Thus, Christianity spread first through the Greek-speaking residents, then later through the Latin speakers. Its literature (what Christians call the Old and New Testaments, and other religious writing from the 1st to 6th c., called “Patristic” literature, that is, “of the Fathers [patres] of the Church”) accounts for most of the volume of work of this period (see below). The central patristic debates (see below) led to several ecumenical councils at Nicaea, Constantinople, Ephesus, and Chalcedon. Those accepting their decisions were named orthodox (“right-teaching”) or Catholic (“found everywhere”), while those who did not were named heretics (variously, Arians (the Goths), Nestorians, etc.).
Philosophically: Central patristic thinkers & debates 1-6th c.: Some of the most notable patristic thinkers included (Greek writers) Athanasius, Chrysostom, Gregory Nazianzen, Gregory of Nyssa, Origen, (Latin writers) Ambrose, Augustine, Jerome, and Gregory the Great. Trinitarian and Christological controversies. Whether Jesus was both God and man, whether he had two natures and their relation, if so, and whether he had a human soul? How the divinity of Christ and the Holy Spirit can be reconciled with the doctrine that God is One?
Historically: Islamic/Muslim Attacks in the 7th c. and the rise of the Carolingian Dynasty: Followers of the prophet Mohammed (d. 632 c.e.) began attacking the Roman empire from the 7th c. onwards. Islam became the dominant religion (and Arabic the dominant language) in the Middle East, North Africa, and some of Spain, although these lands still were home to Jews and Christians, both heretics and orthodox, and their knowledge of Greek, especially Greek medicine, permitted their favor and survival. This was the period of the Islamic Golden Age and saw the massive advance of science and philosophy. Massive translation projects were undertaken around the 9th c. of Greek medical, scientific, and philosophical texts into Arabic (sometimes also Syriac), as well as Persian and Indian writings. In the 12th c., Spain became a center of translation of these texts, as well as Arabic originals, into Latin, often by Jews who knew both Arabic and Latin.
In 732 there was the massive battle between the Christian Franks and the Muslim Moors. The Moors, rightly, saw that Europe was too busy fighting amongst itself. They entered and tore through France, causing widespread casualties. They turned northward and met the Frankish general Charles “the Hammer” Martel, who had seen the threat coming and enlisted a professional army, funded by the Church (rather unwillingly on their part). Charles Martel was an early member of the Carolings, a Frankish noble family, whose power was consolidated in the late 7th c. (known as the Carolingian Dynasty, which usurped power from the Merovingian Dynasty, the former rulers of the Franks, in 751 with papal consent). Charles Martel defeated the Moors. The general was noted as the defender of Christendom, making this victory into an eventual Christian empire, his grandson being Charlemagne, King of the Franks, the first official Emperor in nearly three centuries.
Historically: Carolingian Renaissance and the rise of Charlemagne: (late 8th – 9th c.): The Carolingian Renaissance is one of three commonly designated medieval renaissances. It was a period of intellectual and cultural revival centering in the reigns of the Carolingian rulers, Charlemagne and Louis the Pious. The period hearkened the original Roman Empire of the 4th c. and saw an increase in educational and cultural practices, from writing to the arts, architecture to religious study and reform.
Charlemagne rose to power strongly, viciously and with ruthless religious fervor, beheading all those who failed to convert or were caught worshiping other gods. He never lost a military conquest, rebirthed education, stabilized and rebirthed the financial importance of Europe in the world, and reawakened culture, his empire spreading (at its largest around 800 c.e.) from France to Switzerland to Poland and to most of Italy. This new Holy Roman Empire is as large as the first Roman Empire, albeit not the same exact territory as the original, but it is beginning from near ruin: its infrastructure is mostly rotted and destroyed, its people mostly ignorant. He tires his best to pull Europe from the darkness.
Establishment of the Schools and Intellectual Growth: While Charlemagne himself was illiterate, although took great effort to learn to read and write, he founded numerous schools for children of all ages and classes throughout the empire to increase literacy and address the increasing problem of the court not having anyone who could be scribes and parishes that had no one who could read the Bible and more and more regions developing dialectics unintelligible to the rest of the empire. With the establishment of schools, Charlemagne called leading scholars to his court. This period also saw the invention, by Alcuin of York, of the Trivium and Quadrivium, the form and ordering of subjects of study. Another invention was the Carolingian Minuscule, a script, called a “book-hand,” that introduced clear uppercase letters, invented lower case letters, added spaces between words, and standardized overall the Roman alphabet. This initiated the mass translation of philosophic works into Latin.
Charlemagne ruled for over three decades before being coroneted as Emperor, as which he ruled for over 14 years. In this time, 793 c.e., he faced a vicious onslaught of heathens from the north: The Vikings. They came in and sacked every Church and monastery they found, finding enormous wealth and no fighting back. They quickly moved further and further south, eventually setting its sight at the heart of the empire. The empire paid bribes to the Vikings to keep them back; this impoverished the empire and fostered the Vikings. They vicious raids pushed back much of the advancement that Charlemagne’s reign had produced. The Carolingian Dynasty saw its decline.
The Vikings plundered and ruled for a quarter of a century, until King Alfred the Great (d.899), in the south of England, eventually defeated them in the British Isles. The Vikings persisted throughout the world for another half century or so.
Philosophically: 8th-10th Centuries: Darkness kept philosophy to a minimum, but Carolingian Renaissance inspired some philosophical work to develop educational curriculum, and solicitation of some philosophers to translate and summarize earlier minds, most notably John Scotus Eriugena (ca. 810-877), who systematically fused Christian and Neoplatonic thought. The more remarkable philosophy being done was Islamic: Al-Kindi (ca. 801-873), a Muslim Peripatetic who synthesized Greco-Roman and Arabic/Islamic philosophy and argued its compatibility with theology, thereby codified much of the philosophical vocabulary and themes for later thinkers; Al-Farabi (ca. 872-951), the “Second Master” (1st: Aristotle), wrote commentaries on Aristotle & Plato, synthesized philosophy and Sufism by minimizing Greek/metaphysical tone and emphasizing methodology; and Ibn Sina (Avicenna) (ca. 980-1037) prolific (240 surviving works of phi. & medicine), notable use/development of Neoplatonic emanation theory to build metaphysics advancing Aristotelian existence/essence division by emphasizing precedence of essence (later influential on 12thc. Kalam, ‘school of theological discourse,’ sort of an Islamic Scholasticism).
Al-Kindi (ca. 801-873):
Muslim Peripatetic; sought synthesis of Greco-Roman and Arabic/Islamic philosophy, and argued for compatibility of philosophy and theology. Codified much of the philosophical vocabulary and themes for later thinkers. Considered first systematic philosopher in Islam. 260+ books (phi, geometry, medicine, logic, physics), approx. 25 survive.
Al-Farabi (ca. 872-951):
The “Second Master” (second after Aristotle); precedent to Ibn Sina. Said to philosophically tend away from Greek influence (and metaphysical influence) to emphasize methodology, but, but what metaphysics and theology is there is so very, deeply Neoplatonic; he sought to synthesize philosophy and Sufism, and wrote commentaries on Aristotle & Plato.
High Middle Ages (1000-1300): From the dark, Anselm (1033-1109) starts & defines this period’s Platonism-cum-Aristotelianism rereading logic into mysticism and embracing empiricism, yielding disparate philosophical schools: some reject Plato; some get even more mystical; birth of scholasticism (Aristotelian based method to synthesize arguments to defend dogma). Key to this is the Crusades (nine, from 1095 to ca.1300); again, holy war bad for history, good for finding new philosophy, esp. Aristotle’s oeuvre.
Historically: By the middle of the 11th century: … 600 years of misfortune had faced the Europeans of the middle ages. The Viking threat faded, but a new threat rose from within: the medieval knights themselves. With the end of the Viking invasions, there were a surplus of Knights who had nothing to do. They allied with local lords and became their thugs; they then attacked the local peasants regularly, terrorizing them, taking from them what they needed. The Catholic Church, which spent this century undergoing immense monastic reform, namely in the advancement of general virtuosity, which also inspired secular reform and the advancement of morality, thus, the Church tried hard to control the knights and ease the violence. Often doing this by bringing the knights together at night in open fields lit by fires before large piles of all the relics of the Saints; they commanded the knights to obey them and cease their violence or else the Saints would haunt them. The Church issued two dictates on their stance on war; the Peace of God and the Truce of God (do not fight against those who cannot defend themselves and there should be truce times at night and holidays).
Historically: The Crusades: A better way, though, to busy the knights was to give them a new cause: a Crusade. The first Crusade was ordered by Pope Urban II at the Council of Clermont in 1095. The Crusades began with a vengeance—they were holy wars declared to reclaim Jesus’ home that had been “defiled by heathens” (i.e., called for the liberation of Jerusalem from Muslim control). Tens of thousands of soldiers were mobilized; Jerusalem was recaptured in 1099, as were other regions. 200 years saw nine crusades and the deaths of millions. By the end of the Middle Ages, all Islamic territories in what is today Spain, Portugal, and Southern Italy were captured and Christianized. While the bloodshed was immense, the push to Jerusalem and beyond resulted in the crusaders bringing back the plunder of knowledge. Over the next couple centuries, it spawned a rebirth of trade and architecture (roads and walls and houses, as well as cathedrals and educational centers). Military supply lines led to building of roads and supply of other commodities and encouragement of travel. Populations started to increase. Nevertheless, as the Crusades proceeded, so did the decline of the Byzantine Empire.
Thus, the High Middle Ages see Europe’s overall revival in urbanization, military expansion, and intellectual pursuits. Infrastructure projects saw roads and rivers connecting growing urban centers and trade began to flourish once more. Political power was consolidated under kings (mainly in France, England, and Spain), instead of papal authority (although, most of the empire was considered to be under Christian authority), while new kingdoms in Central Europe, newly converted to Christianity, began to flourish (until the 16th c. brought invasions of the Ottoman Empire).
There were numerous religious movements in the High Middle Ages. The general increase in wealth and security in the lands led to the endowment of land and building of parishes for the Church, which, in turn, increased its influence on the peasants. But, this time also saw a strong increase in what it deemed heretical notions of religion.
Philosophically: 11th-13th c: The 11th c. saw the rebirth of philosophic work with Anselm of Canterbury defending Neoplatonism (following Augustine’s lead), but honing its form into logical proofs. Following Anselm, the 11th-12th c. philosophers increasingly concerned with the problem of universals: mereological questions of the one and the many and whether genera and species exist only in the mind or in reality, and, if in reality, whether they exist in substances or separate from them. These dialectical investigations were logical exercises that held tremendous philosophic weight for answering broader questions about religious philosophical concerns. Two notable 12th c. thinkers in these areas were Peter Abelard and his student, who took an opposing position, John of Salisbury. This century also saw the rise of a new Platonic influence centered in the school of Chartres, notable for its humanistic studies and interest in science and natural philosophy. In addition to Plato and Boethius, Chartres abounded with the writings of Hippocrates, Galen, and Islamic thought, which had preserved Aristotle throughout the early medieval turmoil. Notable thinkers there included Adelard of Bath, Thierry of Chartres, Clarenbaud of Arras, William of Conches, Gilbert de la Porrée, John of Salisbury, and Alan of Lille. The final important movement in 12th c. medieval philosophy is the mystical movement, notably Bernard of Clairvaux and students at the school of St. Victor, who sought to fuse dialectical and mystical teachings. A thinker who blurs these boundaries is Moses Maimonides.
Ibn Sina (Avicenna) (ca. 980-1037):
Arabic/Islamic philosopher with approx. 240 surviving works (most phi., also many medical texts), he is known for his use and development of Neoplatonic emanation theory (influential on 12thc. Kalam (‘school of theological discourse,’ sort of an Islamic Scholasticism)), and his metaphysics, which advances Aristotelian existence/essence division emphasizing precedence of essence. Some of his key works include: Kitab al-Hidaya; Risalah fi sir al-qudar (Essay on the Secret of Destiny) (collected inReason and Tradition in Islamic Ethics (Cambridge, 1985)); Kitab al-Shifa (The Book of Healing), perhaps his major work; Kitab al-Najat (The Book of Salvation), on psychology; Hayy ibn Yaqdhan, on Persian myth; Danishnama-I Alai (The Book of Knowledge for [Prince] Ala ad-Daulah), onlogic, metaphysics, music theory, sciences (English translation edited by Parwiz Mowewedge, 1977).
Solomon Ibn Gabirol (ca. 1021-1058)
Jewish Neoplatonist writing from Spain, his famous work is The Fountain of Life, working from Jewish and Neoplatonic emanation theory and considering theuniversality of substance.
St. Anselm (1033-1109):
Anselm was enthroned as Archbishop of Canterbury in 1093, approximately fifteen years after writing his most famous work the Proslogion, which contains his ontological proof for the existence of God. The Proslogion seeks a single line of argumentation that will first prove (1) that God exists, (2) will then prove that all other things depend upon Him, and finally (3) prove that all the things that we have been told to think about God’s attributes by the religious tradition make sense in regard to Him. In this way faith may gain understanding through the use of reason to support what we are taught by faith. The essence of his ontological proof is that everyone can understand the statement “something-than-which-nothing-greater-can-be-thought,” this is the definition he gives for God, and in understanding it we must believe it to be true, thus believing in his existence.
Omar Khayyam (ca. 1048-1131):
More known for scientific works (e.g., on Euclid’s elements, cubic equations, astronomy, etc.) and poetry (Rubaiyat of Omar Khayyam) than philosophy. Engaged ideas in skepticism and sufism; taught on Ibn Sina’s Healing; worked in phi of math.
Al-Ghazali (1055/8-1111):
A Persian Muslim mystic philosopher and theologian, he was born into a Sufi family (and eventually died) in Tus, a province in Persia (now Iran) and studied Islamic jurisprudence; he became a chief prosecutor in Baghdad in 1091 and widely lectured to massive audiences. He left his career in 1095 for a spiritual crisis; he made arrangements for his family, then gave away all his wealth and took on the life of a poor Sufi; he travelled widely, then resettled in seclusion in Tus. While a mystic, he strongly refuted Islamic Neoplatonism (c.f., Incoherence of the Philosophers), which borrowed its foundation from Hellenistic philosophy (this was a sharp critique of earlier notable Islamic philosophers Avicenna and Al-Farabi; following his text, Averroes wrote a long rebuttal of Ghazali’s work, howevr it had already made its mark on Islamic philosophy); he brought together orthodox Islam (and Shariah law) and Sufism. He is responsible for developing a systematic view of Sufism and integrating it into mainstream Islam. He left behind over 70 books on Islamic sciences, philosophy, and Sufism (in Arabic and Persian). His work was closely read by Western philosophers, including Aquinas.
Yehuda (Judah) Halevi (ca.1075-1141):
Jewish Neoplatonist writing from Spain, hence rich Islamic and Christian veins in his work; his most notable is Kuzari, a dialogue between a Rabbi and his student on divine names.
Hildegard of Bingen (ca. 1098-1179):
German Christian mystic, Benedictine abbess; wrote numerous theological texts, liturgical songs and drama, botanical and medical texts, letters and poems, illuminations. She was offered as a tithe to the Church as a child (sometime between eight and 14 years old), suffered from visions since early youth (she wrote from the age of three), learned to read and write as a child and play music (between 70-80 compositions survive); was elected magistra and Prioress, she founded two convents, one in Rupertsberg and another in Eibingen; at the age of 42, she had a vision wherein God told her to write down her visions, which led to her penning her Scivias (“Know the Ways,” completed in 1151), she received Papal approval (Pope Eugenius III) to document her visions, which led to their credit and quick consumption by readers. She also invented her own alternative alphabet, which she called her Lingua Ignota, and also coined many original and conflated and abridged words. She left behind nine books and over 100 letters and 70 poems.
Ibn Tufayl (Ibn Tufail; Abubekar) (ca. 1105-1185):
Islamic philosopher and author, his famous work is both literature and philosophy: Hayy ibn Yaqdhan (Philosophus Autodidactus), a romantic and allegorical novel inspired by Ibn Sina and Sufism, also responding to Al-G’s Incoherence of the Philosophers, of autodidactic feral child on desert island.
Ibn Rushd (Averroes) (ca. 1126-1198):
Named “The Commentator” (re: Aristotle); Defender of Aristotle (often vs. Al-Ghazzali), most known for minimizing Neoplatonic influence and popularizing Aristotle in Arabic philosophy. His work spans philosophy, logic, medicine, math, astronomy, theology, and law. In metaphysics (vs. Ibn Sina), made existence contingent (not accidental) to essence, hence primacy of (substantial) existence. Tahafut al-tahafut (The Incoherence of the Incoherence), defense of Aristotle vs. Al-Ghazzali.
Maimonides (1138-1204)
Born in Cordoba, the son of a religious judge; schooled in law and medicine. He and his family were driven from Cordoba when he was 13 by the fundamentalist Almohads; they moved to Fez, Acre, then finally settled in Cairo. Maimonides served as the president of the Jewish community there for five years, and then served as the court physician to the vizier of Saladin in 1185. During his life, he was highly regarded for his rabbinic studies and his definitive list of the divine commandments (instead of ten, he counted 613). But, we remember him for the work we are reading selections from, The Guide for the Perplexed.
As-Suhrawardi (ca. 1154-1191):
Founder of Illuminationism, Islamic mysticism built from Platonism/Neoplatonism and Zoroastrianism. Roots in Ibn Sina’s peripatetic philosophy, illuminationism uses and critiques it; develops emanation cosmology wherein “Light” is divine/metaphysical epistemic and ontological source, and emanations resemble Platonic forms down to substance. Also creates a symbolic language. Main works: Treatise on Illumination / The Philosophy of Illumination (trans. Corbin, 1986); The Temples of Light; The Treatise of the Bird; The Calling of the Simurgh.
Rabbi Azriel of Gerona (ca. 1160-1238)
Jewish philosopher; a key work is his “Explanation of the Ten Sefirot,” merging Neoplatonic Emanation theory with Jewish mystical thought.
Ibn Arabi (ca. 1165-1240):
Islamic mysticism; Sufi. Accord with Al-G on law as only means to higher goal, also similar stress on ‘perfection’/‘purification’/‘spiritual exercise’ (esp. explores idea of “mirror”).
St. Bonaventure (1221-1274):
Doctor of the Church, Cardinal-Bishop of Albano, and Minister General of the Friars Minor; he entered the Order of the Friars Minor in 1238 or 1243 and then was sent to the University of Paris for his education under Alexander of Hales (founder of the Franciscan School); he received his “licentiate” to permit him to teach, which he did until a crackdown on the Friars, which barred them from teaching around 1256; he was readmitted eventually and awarded, along with Aquinas, the degree of Doctor in 1257. In addition to the exclusively recognized life of St. Francis, some of his writings are mystical, concerning the perfection of the soul by discharging vice and ecstatic prayer. His other writings are, variously, ascetic, dialogues on spiritual questions, meditations on the life of Christ, a work on the passion, and a treatise on the virtues.
St. Thomas Aquinas (1225-1274):
Aquinas has strong Platonic aspects, and deep respect for some Neoplatonist thinkers, but his foundation and commitment is clearly to Aristotle, who had been reintroduced to Europe only 100 years before, and to whom he was introduced by the newly formed Order of Dominicans, which he joined. His main project (Summa Theologica, over 3500 pages, but unfinished; its parts are made of treatises which present questions, articles, the doxa, his reconciliations, and then refutations in a very precise, logical style) endeavors to systematize the ideas of the Church fathers and philosophers and work out a consistent theology (though, he incorporates numerous new interests and pieces of knowledge into religion as he reconciles the Christian notions of God with Greek philosophy). He argues that truth can be known both by reason and by faith; thus, reason is a tool for faith.On the nature of humanity, he essentially accords with Aristotle’s De Anima: one is a natural being with natural functions and has natural ends, yet, he adds that each is also a child of God and thus has a supplemental end: loyalty and obedience to God. On the nature of God, he works from Aristotle and argues that He is the supreme: pure actuality, pure intelligence, and a being whose perfection inspires the universe’s movement, yet adds that God is also creative providence, loving father, and exacting ruler.
Aquinas’ Influence on Philosophy and Theology: From the 14th c. on, Aquinas’ thought was widespread tremendously influential (in 1342, the general chapter of the Dominican Order declared his thought to have been deemed sound throughout the world); between his death and the 14th c., however, his thought was shadowed by controversy. By the mid-14th c., his Summa Theologica replaced Lombard’s Sentences as the text book of Catholic theory in the Dominican schools. Its adoption was even wider spread after his being named a Doctor of the Church in 1567. In the 17th-18th c., his influence saw its decline in the general critiques of Scholasticism that were popular (Descartes is often cited as its last destroyer, although the French Revolution’s attack of ecclesiastical studies may have had equal impact). The 19th c. saw the revival of Scholasticism (Pope Leo XIII in 1879 declared Aquinas’ philosophy to be the true Catholic philosophy) and the development of “Neo-Thomism” (the Second Vatican Council, 1962-65, named Aquinas’ thought as the “perennial philosophy”). (Thomism: names the school or system of philosophy that follows Thomas’ teachings, however, it is generally used to refer to a philosophy/theology wherein syntheses of Greek, Jewish, and Islamic philosophy are melded with Christian philosophy and doctrine; predominately Aristotelian-Christian thought; Neo-thomisms span existential to transcendental to analytic veins).
John Duns Scotus (1265/6-1308):
A Scottish philosopher likely educated in England (reputedly Cambridge and Oxford, as well as Paris) and ordained a Franciscan priest in Northampton, England; he lectured in Paris, in between expulsions for political-theological disputes, and in Cologne, where he died in 1308. He was beatified by Pope John Paul II in 1993. He is the founder of “Scotism,” a form of Scholasticism; also dubbed “Doctor Subtilis,” for the delicate nuance of his thought, almost to the charge of sophism. His intellectual legacy includes doctrines on the “univocity of being” (existence is most abstract and applies to all; follows Aristotle’s assertion that the subject matter of metaphysics is being qua being; his doctrine denies a real distinction between essence and existence (contra Aquinas), that is, between whether something is and what it is), the “formal distinction” (distinguish different aspects of same thing), “haecceity” (that which individuates a thing), a proof for the existence of God (an a posteriori proof, proceeding from His effects; uses a causal argument), and argument for Mary’s immaculate conception (which caused tremendous opposition).
William of Ockham (ca. 1287-1347; and following him, the Ockhamist School):
With Duns Scotus and Aquinas, perhaps most notable thinker of this period, but certainly the most famous for his so-called “Ockham’s Razor” principle, which expresses a nominalist desire in its command to ‘not multiply entities beyond necessity’ (albeit this is his sentiment, not actually how he expresses it), meaning that one should not posit the existence of entities without really compelling reasons (that is, knowable and known reasons, so far more than just ‘sufficient reason’) to do so because we humans lack clear, let alone indubitable, knowledge of necessity beyond the fact that God is a truly necessary entity.
Late Middle Ages (ca. 1300-1600): With the former period’s proliferation of schools, philosophy of the 14th c. characterized by most popular schools (all logic-leaning) merely attacking each other and amplifying the schism growing between philosophy and theology in following centuries. Rejecting mysticism and metaphysics, embracing empiricism set the stage for the Scientific Revolution and Renaissance humanism. Most say Middle Ages ends in 1453 (fall of the Byzantine/Eastern Empire), but philosophically, distinctly medieval work written centuries after (e.g., Teresa of Ávila (1515-82), John of the Cross (1542-91), Mulla Sadra (1571-1640)), Renaissance attention to esoteric traditions yielded works more medieval than modern (e.g., Agrippa’s 1533 De occultaphilosophia, Patrizzi’s 1591 Nova de Universis philosophia, John Dee (1527-1608), Pico della Mirandola (1463-94) and Isaac Luria (1534-72) et al on Kabbalah), and distinctly modern philosophers’ reverberations of medieval process/problems (e.g. Descartes (1596-1650) and Copernicus’ 1543 De Revolutionibus’ and Kepler’s 1619 Harmonices Mundi’s considerations of hermetica).
Historically: From the comparatively flush good times of the High Middle Ages, the Late Middle Ages began with crisis. The first factor was the Great Famine (1315-17), the next was the Black Death, which killed a third of the population by the mid-14th c. The increased populations and urbanization from the High Middle Ages permitted the effects of famine and disease to spread rapidly and be felt intensely. The new and sharp decrease of populations led to shortages of workers and popular uprisings. The Church also suffered strongly from internal rifts. Nevertheless, amongst the calamities of these times, innovation and intellectual life continued to be strong.
There was a strong rise of nation-states in this period, especially the Kingdoms of England and France (and others along the Iberian Peninsula), precipitated by the Hundred Years’ War (1337-1453) between those two kingdoms, mainly over claims by the English kings to the French throne. The war led to the decline of the fortunes of both kingdoms, although increased nationalism in each.
The Church suffered from great disarray in the 14th c.: The Avignon Papacy was one initiating disaster: a deadlocked conclave elected Clement V as pope; he was a Frenchman and decided to keep his papal enclave in France, in Avignon, instead of moving to Rome. This was a deep offense to Rome, and persisted 67 years, which the Romans called the “Babylonian Captivity of the Papacy.” Seven popes stayed in Avignon, all of them French, each increasingly under control by the French crown. It was not until 1377 the Gregory XI moved his court to Rome that this period ended. Western Schism: The Avignon Papacy led to the build up of the Western Schism (1378-1417). This schism led to the birth of a second line of popes (now considered illegitimate)—that is, two different men deemed themselves to be pope. Gregory XI died, which ignited the Romans to riot to insist on the election of a Roman pope; the cardinals elected Pope Urban VI in 1378, but he turned out to be a fierce and suspicious man with a violent temper; the cardinals fled to Anagni and elected Robert of Geneva (cum Pope Clement VII) as a rival pope (antipope), who then reestablished court in Avignon. The schism was ended by the Council of Constance in 1414-18. This religious turmoil quickly became a political, diplomatic crisis, splitting the Continent. The Schism continued until after the deaths of both the popes. Force and diplomacy failed to solve the problem; eventually, a Church Council was called in Pisa in 1409. This council only succeeded in making matters worse: they elected a third pope, Alexander V, who ruled for a year before dying, upon which, John XXIII took his position. The Church now had three popes. Finally, the Council of Constance met in 1414 and secured the resignations of John XXIII and the Roman successor, now Pope Gregory XII, and excommunicated the Avignon Pope Benedict XIII, who refused to resign. The council then elected Pope Martin V. Rival factions persisted and a few more antipopes were elected, but the schism was mostly over. (Although it took until well into the 19th c. for the history to be cleared up as to who was real, who was anti-, etc., with some records remaining blurry until the 20th c.) Martin Luther and the Protestant Reformation: The turmoil gave the widespread impression of its clear corruption. While disdain had been building for a while, the turmoil prevented the complete silencing of dissidents; taking advantage of this, Martin Luther (1483-1546) published his objections against the Church, Ninety-Five Theses (mainly against the Catholic practice of Indulgences, payments for holy favor), in 1517. They were translated from Latin into German in 1518, printed, and widely copied and read (first protest aided by the printing press). Students flocked to Wittenberg to hear him lecture. He refused to retract his statements, demanded by Pope Leo X in 1520 and by the Holy Roman Emperor Charles V at the Diet of Worms in 1521, and was excommunicated by the former and condemned as an outlaw by the latter. The Lutherans split from the Church in 1517 (organized by Luther et al in 1526-9), launching the further division of Catholicism from Lutheranism, Calvinism, and Anabaptism.
Historically: 15th Century: By its end, the Ottoman Empire advanced throughout Eastern Europe and conquered the Byzantine Empire and Slavic states. The key battle ground was Hungary, the edge of the Christian world. John Hunyadi, a great military figure, was named its regent-governor, and he succeeded in several massive victories against the Ottomans (these battles were cast as holy wars, Christians versus the Muslims). His son, Matthias, succeeded him as the King of Hungary and continued the campaigns against the Ottomans with papal support, eventually building the largest army of its time (called the Black Army of Hungary, mainly composed of mercenary soldiers), and repelling and stopping all attacks. Literati, artists, and scientists flocked to Hungary (the second site after Italy of the Renaissance), and the largest library of the age, the Bibliotheca Corviniana, was built. After Matthias died, the army disbanded and the Kingdom was left defenseless. They resisted the Ottoman resurgence of attacks until 1526, but then caved before the Ottoman power and the West’s general turmoil and weakening of its support by the Church due to the Protestant split. The fall to the Ottoman Empire generally signals the end of the Medieval period.
Philosophically: 14th-15th c.: Philosophy in the 14th c. is often characterized by its contrast to the earlier centuries, thus as a decline of such philosophy and rise of a destructive critique. There was a more-or-less firm solidification of philosophy into competing schools: Thomism, Scotism, Albertism, and Nominalism. There was also the argument for the divorce of philosophy from theology, which would signal the end of Scholasticism and the end of medieval philosophy. There was also a growing doubt in metaphysical presumptions to knowledge and a more welcoming stance to empiricism (as is notable in Early Modern philosophy). In general, the attention had been turned from the relation of the soul to knowledge as an activity to knowledge as demanding evidence and seeking claim to validity and/or certainty. By the 15th c., philosophical debates had divided the “older way” (via antiqua) from the “modern way” (via moderna) of thinking, the latter predominately nominalism as bolstered by William of Ockham (Ockhamist School) and John Buridan.
Nicholas of Autrecourt (ca. 1295/98-1369):
Probably French born (possibly English) philosopher connected to Sorbonne, although perhaps controversially, as he is most well known for having been tried by Pope Benedict XII in 1340 for ‘false teaching’ and convicted in 1346; there is ambiguity about whether he received a degree, permission from the Holy See for it, or not, although he is known to have taken a license in theology and was given a position as canon then dean of the cathedral in Metz, although the charges were concerning 66 purported claims in his written and oral teachings as being everything from false to heretical. Of the minimal writings we have, there are topics across all areas (theology to natural philosophy to ethics); what is clear is that a main concern was epistemological: evidence necessitates reduction to a first principle (i.e., certain knowledge must be able to be reduced back to the principle of non-contradiction), which reveals an anti-Aristotelian logical position (for Aristotle allows induction to discover the existence of things due causal relations). So, for Autrecourt, logica does not give us proof or even reason to assume that there is an evident relation between substances and attributes or causes and effects (i.e., think Hume’s skepticism).
Marsilius of Inghen (ca. 1340-1396):
Philosopher born, probably in what is now the Netherlands, but is associated with Universities of Paris and Heidelberg; while a defender of Thomism, he worked from Ockham and Buridan’s linguistic-logical bent, hence reveals a mediating voice between realism-nominalism debates. His many works especially cover the old-and-new reconciliations in logic and epistemology, but also commentaries (as summary and questions) on Aristotle’s physical, metaphysical, and ethical works, as well as a more strictly theological work of questions on Lombard’s Sentences.
John Buridan (ca. pre-1300-shortly after 1361):
French philosopher known for his nominalist theories and associated with University of Paris as student, teacher, and rector (and, hence, unusual that his ‘place’ is strictly within the university, and not connected to a religious institution); and while historical fact is scant, the stories and legends are many (was he murdered by the king for an affair with the queen?, is he responsible for the famous memory of Pope Clement VI because he assault him, pre-pope days, in a squabble with a shoe over a shoemaker’s wife?, etc.). His notable works are his commentaries on all the major works of Aristotle and a formidable and highly influential textook on logic (the Summulae de dialectica, Compendium of Dialectic); together, these forged ideas of language and logic for early modern philosophy.
NOTES: [1]Hermeticism, a religious-philosophical dialogic system attributed to the Egyptian Hermes Trismegistus (ca. 200 b.c.e-200 c.e); advocates the One as ultimate source in a tripartite system; entails a mystical doctrine concerning alchemy, astrology, and theurgy. Gnosticism (gnosis, knowledge), attributed to Alexandria, Athens, Rome, and greater Indian empires with affinities to Judaism to Buddhism, promises salvation through mystical knowledge via pantheistic, idealist, and dualistic truth of divine union vs. entrapment in degradations of matter. Chaldean Oracles (surviving fragments), 2nd c. Hellenistic commentary on a mystical poem attributed to Zoroaster (Iranian prophet, arguably ca.1000 b.c.e -7th/6th c. b.c.e), presumed founder of synthetic, oldest extant religion both dualistic/monotheistic emphasizing dichotomies.
[2] Speusippus, quoted in Dillon, Heirs of Plato, 44, and Dillon himself, respectively. All that is includes multiplicity’s creation of the realm of Soul, responsible for geometrical extension, the generation of all other souls in the universe, the physical world, celestial bodies, earthly body, thought, language, instinct and passions, the Good, and motion and repose (Ibid., 40-53).
[3] Goodness, evil, all other Platonic Forms are housed within the World-Soul (such prohibited in highest realms: he “wished to deny ‘goodness’ both to the primal One, and even to the mathematical and geometrical levels of reality, not because they were bad, but simply because he felt that the term had no real meaning at those levels” (Ibid., 53)).

[6]Proclus (412-485 c.e.): ‘Greek’ Neoplatonist philosopher; born in Constantinople, studied in Alexandria, returned home to practice law, abandoned law in 431 to study philosophy at the Plato’s Academy under Plutarch, Syrianus, and Asclepigenia, before becoming the head of the Academy. Spent the rest of his life there, minus one year of exile (his philosophy unfavorable to the Christian rule), when he travelled widely and was reputedly initiated into many different “mystery cults.” Most of his works are commentaries on Platonic dialogues, faithful to them and original; had an influential commentary on Euclid’s Elements of Geometry; his original system in two treatises, the Elements of Theology and the Platonic Theology.
