Preface
"We are like dwarfs," wrote Bernard of Chartres, "seated on the shoulders of giants; we see more things than the ancients and things more distant, but this is due neither to the sharpness of our own sight, nor to the greatness of our stature, but because we are raised and borne aloft on that giant mass."1 In the search for truth, modern Western philosophers stand on the shoulders of the "giant mass" of ancient and medieval thinkers whose ideas they have inherited.
Western civilization lives by the ideas that animate it." This book is written for students
making their first acquaintance with these ideas in the history of philosophy. The author’s chief
purpose is to introduce students to the origin, development, and interconnection of philosophical ideas. To achieve this goal, emphasis has been placed upon making the major ideas of the medieval philosophers accessible to the reader in a direct, clear, and informative manner. This history of philosophy is intended, not as an end, but as a means of introducing the reader to a more extensive
and intensive study of the philosophers’ writings and of their interpretations by specialists in
various fields.
When the student is first acquainted with the myriad ideas of medieval thought, they may appear to him widely elusive, hopelessly incoherent, and even self-contradictory. It is the taunting, tantalizing challenge of the history of philosophy to discover the overall pattern of interrelated meaning. With this insight one can savor the distinctive contribution of each man or movement.
In understanding the meaning of philosophical ideas, one has not only factual information but an appreciation of what philosophizing meant for Augustine, Thomas Aquinas and William of Ockham. What better way is there to learn to philosophize than to observe the great philosophers of the past? This history of philosophy is intended as an introduction to the process of philosophizing itself. With adequate knowledge of the history of philosophy, one can share in the collective enterprise of philosophizing which has occupied the mind of Western man for twentyfive centuries.
To disclose effectively the pattern of meaning in the history of medieval philosophy, the historian of philosophy must keep in mind two aims. First, he must discover the spirit of an age by fathoming.

Chapter I
Augustine: The Lover of Truth
Augustine "was, to a far greater degree than any emperor barbarian war lord, a maker of history and a builder of the bridge which was to lead from the old world to the new."1 He was the bridge between ancient and medieval thought and the founder of philosophy in the Middle Ages. In his passionate pursuit of truth and happiness, Aurelius Augustine’s life spiraled through three spiritual states: conversion, enlightenment, and unity.
Life2 and Works3
- Conversion. Augustine was born in Tagaste (modern Souk Ahras, Tunisia), A.D. 354, of a
Christian mother, Monica, and a pagan father, Patricius. An offspring of the dying ancient civilization and the emerging Christian culture, he experienced a powerful inner conflict of values. During his studies of literature and grammar at Madaura and his higher education in rhetoric at Carthage, he reveled in "the ways of Babylon" and enjoyed the Circes of sensuality. For fifteen years he lived with a mistress by whom he had a son Adeodatus. He taught rhetoric and eloquence at Tagaste, Carthage, and Milan. Outwardly, he was pleased with the ensuing fame, but inwardly, he was discontented as his mind searched for enlightenment.
He embraced the Manichean dualistic teaching that there are two ultimate principles, one responsible for good and for the human soul, the other for evil and matter, including the body.4 Dissatisfied with the materialism of Manichaeism and unable to find a basis for certitude in his experience, he adopted the skeptic attitude of the Platonic New Academy. On reading some "Platonic treatises" in the Latin translation of Victorinus, Augustine overcame his doubt about the possibility of a spiritual reality and found his way toward reconciling the presence of evil in the world with the Christian teaching of divine creation.5
- Enlightenment. Enlightened by the writings of St. Paul and the holy life of St. Anthony of
Egypt, Augustine experienced a strong desire to improve his way of life. To that end he retreated for a year (3861387) with some friends to Cassiciacum outside Milan where he underwent a religious conversion and wrote Against the Academics — a justification of truth and certitude
— On the Happy Life, On Order, the Soliloquies — a discourse on God and the soul — On the
Immortality of the Soul, and On Music. After his spiritual seclusion, Augustine and Adeodatus were baptized by St. Ambrose.
- Union. While residing at Rome (387-388), Augustine composed two philosophical
dialogues, On Free Choice and On the Magnitude of the Soul — on the operations of the soul.
After returning to Tagaste (388), he sold all his inheritance and established a small monastic community. Not long after writing On the Teacher — a study of knowledge — he was ordained a priest (391), and later, by popular acclaim, was consecrated Bishop of Hippo (395/396). His numerous sermons against the Manichaeans, Donatists,6 and Pelagians,7 his many theological treatises and letters, testify to his unceasing concern for the faith of his fellow Christians.
Notwithstanding his pressing episcopal duties, Augustine wrote three magna opera: the
Confessions (400) — an autobiography of his personal relationship to God — On the Trinity (400- 416), and the City of God (413-426) — a defense of Christianity and an exposition of the meaning of history. His work On the Nature of the Good responds to Manichaeism, his treatise On the Soul and Its Origin replies to Donatism. Toward the end of his life, he critically scrutinized his earlier
7
writings in the Retractions which chronologically enumerates his ninety-four works, explaining their purpose and making revisions. Appropriately, his last complete opus was On the Gift of
Perseverance (428), expressing his mind’s and heart’s unceasing search for truth and happiness
which he found ultimately in union with God. Augustine died in 430 as Genseric and his Vandals laid siege to Hippo.
Encounter
Within the cultural crisis of the Roman Empire, Augustine encountered spiritual problems concerning God and the soul, faith and reason, Christianity and history.
Problems
I. Emergence of Problems
The cultural crisis which the Roman Empire experienced during the time of Plotinus intensified in the fourth and fifth centuries as the barbarians increased their pressure on the feeble frontiers and political discontent grew among peoples subjugated by Rome. As the political and
economic order deteriorated, imperial authority became more dictatorial to stabilize the empire’s
vast structure, and the populace in turn lost its time1honored freedoms and civic concern. Military might rather than law bound the body politic together.
The religious element in ancient culture, which had been the inspiration of civic patriotism in the fifth and sixth centuries B.C., had almost disappeared from the cosmopolitan civilization of the imperial age. The temples and gods remained, but they had lost their spiritual significance and had become little more than an ornamental appendage to public life and an occasion for civic ceremonial.8
As the old ideals retrogressed, the new spirit of Christianity emerged to revivify classical civilization.
II. God and the Soul
Like Plotinus, Augustine saw that the core issue of the Roman Empire was not military, or political, or economic, but spiritual, and that the ultimate question concerns God and the soul. "God and the soul, I desire to know. Nothing more? Nothing whatever."9 Augustine added to the ancient Greek maxim, "Know thyself," to make it, "Know God and thyself."
III. Faith and Reason
To gain a deeper insight than ancient philosophy into the spiritual problems surrounding God and the soul, Augustine shifted the philosophical perspective from the purely natural level of Plotinus to the supernatural framework of Christian thought.11 Within this religious context, he was confronted with the relation of faith and reason: Can pure reason operate on its own or does it need faith to relate man to God? Can faith without the companionship of reason pursue wisdom?
8
IV. Truth
Intent on refuting the skepticism of the New Academy, Augustine investigated all the truths
necessary for the soul’s pursuit of God. At the outset, he attempted to determine whether certitude
is possible and what truths the mind can know without doubt. Secure on the arch of certitude, he could inquire into the structure of the universe in which the soul finds itself. Central to his concern was the nature, origin, and destiny of the soul, the conclusions to which would affect his attitude toward the mystery of God and his relation to the world. Underlying all these problems is the metaphysical question of how mutable, temporal, contingent beings are related to God, the unchangeable, eternal, necessary being. How can creatures which are continually becoming "other" in time be related to God who remains unceasingly the same in eternity?
V. History
Viewed historically, the metaphysical problem becomes a question of whether the continually changing phenomena of history show a constant intelligible meaning. The event that occasioned
this historical problem was Alaric the Goth’s sacking (410 A.D.) of Rome, the "eternal city." This
catastrophe shook the western world and demoralized the pagans who blamed the Christians for turning citizens from service by teaching renouncement of the world and for weakening patriotism by inculcating forgiveness of enemies. Besides, the God of Christianity, unlike the traditional gods who have been abandoned, has failed to protect Rome. In the face of this indictment, Augustine became attorney for the defense of Christianity.
Themes
In his encounter with these problems, Augustine unfolded three basic themes: God and soul, knowledge of truth, and love.
I. God and Soul
In developing a Christian philosophy as a plan for the renewal of western thought, he centered human existence around the soul and God. Analysis of his own experience revealed three unfailing drives of existing, knowing, and willing, for being, truth, and goodness — in fine, for happiness. Within this context, philosophy is love of wisdom for the attainment of happiness.11 The soul’s unceasing search for knowledge and love is, in reality, the journey to beatitude in God. As Augustine put it in his response to God, "You have made us for yourself, and our heart is restless until it rests in you."12
II. Knowledge of Truth
The quest for happiness reveals two ways of knowledge, perception and understanding. So mutable and temporal are the outer objects of the senses in the Neoplatonic world of Augustine that the soul finds it better to turn within itself to the intelligible realm where it discovers unchangeable, eternal, necessary truths in which it enjoys certitude. Since "no creature, howsoever rational and intellectual, is lighted of itself, but is lighted by participation of eternal Truth,"13 the soul finds itself illumined by God in its quest for truths.
9
III. Love
By willing the truths which he discloses in knowledge, man attains true wisdom and happiness. However, weak human will wavers from seeking the good it ought to pursue. Mutable man cannot seek unchangeable moral truths, unless his will freely submits to the moral illumination of virtue streaming from the immutable and eternal light of divine virtue in God. All
ethical truths, such as "live virtuously," or "live according to God’s law," are reducible to one truth:
love God. Happiness consists of sharing in the unchangeable, eternal love of God.
Method
Augustine developed his themes according to a religious, affective, personal, introspective, synthetic approach. His approach in general, combines the rational way of Hellenistic philosophy with the volitional way of Judaeo-Christian tradition.
I. Religion
As Augustine wandered from one philosophy to another (Manichaeanism, skepticism, and
Neo-Platonism), he became personally aware of the limitations of human reason. Reason and faith
need to cooperate intimately in the soul’s quest for God. Belief is natural and necessary for intellectual activity which assents to many opinions solely on another’s testimony. "We believe
the things which are not present to our senses, if the evidence offered for them seems sufficient,"14 and the authority "of who may be believed is being considered."15 Religious belief and understanding are complementary: "Understand my word in order to believe, but believe God’s word in order to understand."16 Belief enlightened by understanding becomes a reasoned faith. On account of his close correlation of faith and reason, Augustine often made philosophical reflections in the course of theological inquiry and scriptural exegesis. Within this framework of
philosophy and religion, Augustine’s Christian faith was open to whatever insights Greek and
Roman thinkers had to offer.
II. Affectivity
Like Plato’s integration of love (eros) with wisdom (phronesis) in the pursuit of good,
Augustine’s method is highly affective as well as intellective. Love moves the soul to believe and
to know: "Love it is that asks, love that seeks, love that knocks, love that reveals, love, finally, that assures the permanence of what is revealed."17 Love of God brings the soul’s understanding of faith to fruition in a good life. The vision of truth is the prerogative of him who lives well, prays well, and studies well,18 for God shows himself only to one who seeks truth "piously, chastely and diligently.19 Since the wisdom of man is sanctity," it needs love inasmuch as "no good can be perfectly known unless it be perfectly loved."20
III. Person
Augustine is more concerned about the person than problems of the cosmos. Augustine’s disclosure of the soul’s quest for God is highly personal in its starting point, procedure, and
termination. He often begins by unfolding the evil and misery of the individual human condition
10
to stress the need of turning to God. The Augustinian pattern of the soul’s itinerary to God advances
"from the outer to the inner" forum of the soul and "from the lower to the higher"21 personal center of the Divine. The guiding principle in this far-reaching flight of the Augustinian mind is the causal relation of the mutable to the unchangeable. For instance, Augustine reasoned that immutable Truth or God is the sole sufficient reason for eternal truths in temporal human existence. Augustine’s philosophy is an I-Thou encounter between the self and God.
IV. Interiority
Augustine’s personal approach to truth is a profoundly interior way akin to the route of
Plotinus. "Do not go abroad," he wrote, "return within yourself. Truth dwells in the inward man."22 The outer sensible world is changeable and uncertain. Clarity of thought, depth of understanding, and ardor of heart lie in the inner intelligible realm of the soul.
Thus admonished to return unto myself, I entered into my innermost parts under Thy guidance. I was able, because Thou didst become my helper. I entered in and saw with the eye of my soul the Immutable Light.23
As the Plotinian mind ascends inwardly through three degrees of cognition — discursiveness, intuition and ecstasy, so the Augustinian mind rises through inferior reasoning, superior reasoning, and the beatific vision to God. The similarity is striking, yet there is a world of difference between the climax of these two approaches. For Plotinus, ecstasy is a natural outcome of what precedes whereas, for Augustine, the vision of God is a pure gift of God to which man has no natural claim.
V. Synthesis
Augustine’s method, notwithstanding his genius for analyzing human experience in the Confessions, is generally synthetic in purpose, procedure, and perspective. With the soul’s
quest for God as his guiding principle. Augustine stressed the unity of reality rather than its multiple aspects by collecting his concepts into a unified structure. His eminently theocentric orientation inclined him towards organizing all beings under God rather than in specializing in a detailed analyses of creatures in themselves. Deeply concerned about the meaning of human existence rather than a detached analysis, Augustine communicated the living unity of his own personality by synthesizing his thoughts within the single Christian framework of a believer seeking understanding.
Influences
As he reflected on the relation between the human and the Divine, Augustine was influenced by both philosophical and Christian ideas.
I. Platonism
From the vantage point of faith, Augustine took a definite stance toward Greek and Hellenistic philosophy: he rejected skepticism and Epicureanism, accepted some Stoic teachings,24 admired Aristotle as "a man of eminent abilities, yet unequal to Plato,"25 whom he extolled as "the wisest
and most erudite man of his day . . ."26 Most of Augustine’s acquaintance with the essentials of
Plato’s thought was via Christian Platonists and Neo-Platonists such as Plotinus who exercised an
11
intensive and extensive influence on the content and technique of Augustine’s philosophy.27 No
Father of the Church proved more courageous in Christianizing Platonism and more prudent in Platonizing Christianity than Augustine.
II. Plotinus
Like Plotinus, Augustine centered his thought around God and the soul. Whereas Plotinus reflected upon his own personal religious views, Augustine philosophized within a Christian framework. While the Plotinian mind had moved on the natural order with a rightful claim to reach the divine reality, Augustinian reason, to escape skepticism and to understand Judaeo1Christian
revelation, adopted Plotinus’ interiorism and progressed inwardly and surely within the
supernatural order of divine life gratuitously established by God and manifested by faith. This
drive toward God came from Augustine’s indomitable desire for truth, an enthusiasm inspired by his reading of Cicero’s Hortensius.28
Response
The influences that came to play in Augustine’s development of his main themes as a response
to the problems of creatures and God, were conditioned by his notion of philosophy.
For Augustine, the goal of philosophy is happiness. Since man has been impressed with the natural desire for happiness,29he philosophizes like Socrates to find happiness in the possession of truth. That is why Augustine investigated truth in its different dimensions: knowledge of truth, the existence of divine truth, created truth, love of truth, and the history of the love of truth. "O Truth, Truth — how deeply even then did the marrow of my mind long for Thee, when they sounded Thy Name to me, . . ."30 Whereas Plotinus was concerned with the unity of reality, Augustine focused on its truth.
Knowledge of Truth
Augustine’s theory of knowledge, which refutes Pyrrhonic Skepticism and justifies the soul’s
point of departure to God, progresses through four basic stages: sensation and intellection, inferior and superior understanding, knowledge of truth, and illumination.
I. Sensation and Intellection
In the Platonic tradition, Augustine held that sensation reaches only changing, temporal, contingent phenomena,31 and yields no more than opinion, whereas intellection attains unchanging, eternal necessary objects. Dreams and illusions confirm the limited value of the senses and their powerlessness in distinguishing between reality and its false images. The "judgment of truth" is the work, therefore, not of the senses, but rather of the mind.32
II. Inferior and Superior Understanding
In view of its different objects, Augustine distinguished between inferior and superior intellection. Inferior reason is "rational knowledge of temporal things,"33 whereas superior understanding is "rational knowledge of eternal things."34Lower reason relies on the senses in its
12
orientation towards action, while higher reason operates independently of sensation ln its contemplation of truth. "There is a difference between the contemplation of eternal things and the action by which we use temporal things well; the former is called wisdom, the latter science."35 Augustine preferred contemplating wisdom of divine things to the scientific use of corporeal objects, though the latter is necessary for life.
