Where We Are

Lesson 10 left Plotinus's ladder standing: the soul's ascent from matter toward the One, evil explained away as privation. Augustine climbed it and reported something Plotinus never had: at the top, not an impersonal One but a Person, who had been looking for him all along. In Augustine the ancient world's philosophy flows into Christianity. With him Module 2 ends, and so does antiquity itself.

The Historical Moment

Consider the whiplash. In 303 Diocletian launched Rome's last and worst persecution of Christians: churches demolished, scriptures burned, believers executed. Ten years later Constantine's Edict of Milan (313) made the faith legal; in 380 Theodosius made it the empire's official religion. A child who watched neighbors die for Christianity could have lived to see paganism become the career liability. Augustine, born in 354 at Thagaste in Roman North Africa (modern Algeria), grew up in this turned-over world.

Then, in August 410, Alaric's Visigoths sacked Rome — the city's first foreign capture in eight hundred years. Refugees streaming into Africa carried a pointed question: Rome stood while she honored her old gods, and fell within a generation of banning them. Coincidence? Augustine would spend thirteen years answering. Beneath the politics lay the era's deeper question: now that revelation claimed the throne of truth, what work was left for reason — for the whole Greek inheritance? Augustine's answer was his own life, and he wrote it down.

A Life, Confessed

We know Augustine more intimately than anyone else in antiquity, because around 397 he wrote the Confessions, the first introspective autobiography in Western literature — addressed not to readers but to God. We are eavesdropping on a prayer. Its opening states the thesis:

Thou madest us for Thyself, and our heart is restless, until it repose in Thee.

— Augustine, Confessions 1.1 (trans. E. B. Pusey)

Every desire in the book — sex, applause, philosophy itself — turns out to be this one desire, misaddressed.

The story: a clever boy from an ambitious provincial family — pagan father, relentlessly Christian mother, Monica — is sent at seventeen to study rhetoric in the big city. "To Carthage I came, where there sang all around me in my ears a cauldron of unholy loves" (3.1, trans. Pusey). He took a concubine, who stayed fifteen years and bore his son, Adeodatus. At eighteen, a set text — Cicero's Hortensius, now lost — lit in him the love of wisdom (3.4).

Wisdom's first salesman was Manichaeism, the religion of the Persian prophet Mani: the universe as a war between two eternal powers, Light and Darkness. Its appeal was philosophical: it solves the problem of evil — if God is all-good and all-powerful, why is there evil? — by denying the omnipotence. God is not responsible for evil; He is fighting it, not yet winning. Nine years an auditor (lay hearer), he waited for the celebrated bishop Faustus to tie off the system's loose ends. Faustus arrived: charming, eloquent, unable to answer Augustine's astronomical objections (5.6–7). Drawing the Socratic moral — eloquence is not knowledge (Lesson 3) — he drifted into Lesson 9's Academic skepticism, lived rather than read: perhaps nothing can be known. Meanwhile his career soared: Rome, then Milan in 384, professor of rhetoric to the imperial court.

Monica, who had followed him to Milan, arranged a brilliant marriage; the concubine was sent back to Africa as "a hindrance to my marriage"; "my heart which clave unto her," he writes, "was torn and wounded and bleeding" (6.15). She vowed to know no other man; he took an interim mistress while his child fiancée came of age. He tells this on himself. Say it plainly anyway: his ambition cost an unnamed woman everything, including her name.

Two liberations followed. Bishop Ambrose taught him to read Scripture non-literally, dissolving his cruder objections; and "certain books of the Platonists" — Plotinus's school in Marius Victorinus's Latin (7.9) — gave him what Lesson 10 gave you: immaterial reality, evil as privation. His mind was convinced; his will would not move. The deadlock broke in a Milanese garden in August 386: weeping under a fig tree, he heard a child chanting tolle lege — "take up and read" — opened Paul at random to Romans 13:13 ("not in rioting and drunkenness, not in chambering and wantonness..."), and "instantly... all the darkness of doubt vanished away" (8.12). After a retreat at Cassiciacum he was baptized by Ambrose at Easter 387, Adeodatus beside him. Monica died at Ostia months later, days after a vision they shared (Book 9); Adeodatus died young soon after. Back in Africa a congregation press-ganged him into the priesthood at Hippo in 391; by 396 he was its bishop, for thirty-four years. He died in August 430 with the Vandals besieging the walls — the ancient world ending outside his window as he left it.

Believe, That You May Understand

What is reason for, once you have revelation? Augustine's formula became the medieval West's: crede ut intelligas — "believe, that you may understand" (Sermon 43.7, our close rendering). Not faith instead of thinking: trust comes first in all serious knowing — you trusted parents, teachers, every map you never verified — and understanding grows inside it. Reason is not fired; it is given a home and a job.

First job: explain knowledge itself. How does a changing mind in a changing world know unchanging truths — that seven and three make ten, that justice beats injustice? Augustine's answer is illumination: Plato's Forms (Lesson 4) relocated into the mind of God, known because God's intelligible light shines on the mind as the sun makes objects visible. The sun outside the cave now has a face. Plato, baptized.

But can we know anything? Augustine's answer to the skeptic is a preemptive strike:

If I am deceived, I am. For he who is not, cannot be deceived; and if I am deceived, by this same token I am.

— Augustine, City of God 11.26 (trans. Marcus Dods)

Run the worst case: suppose every appearance is false. Deception still needs a victim; being wrong proves a someone who is wrong. Si fallor, sum. Twelve centuries later, Descartes will set almost this exact stone as the foundation for rebuilding all knowledge, science included (Lesson 21). Mark the difference: for Descartes the certain self grounds physics; for Augustine it is a rung — the soul that finds truth within itself must look above itself, to the unchanging Truth that makes truth possible. Same step, different staircase.

Evil and the Divided Will

The Manichaean question never released him: where does evil come from, if not from a second power? Plotinus supplied half the answer: evil is privation, a hole in goodness, not a substance — blindness is missing sight, not a thing (Lesson 10). So God created no evil thing. But holes do not dig themselves. Augustine supplies the shovel: free choice, the will turning from greater good to lesser. Moral evil originates not in matter, not in Darkness, but in us.

He knew the choosing self from the inside. In the garden crisis he could command his hand and it obeyed, yet command his will and it refused: "two wills" at war in one man (8.9–10) — not, he insists against his old Manichaean self, two souls, but one self divided. Aristotle's akrasia (Lesson 7) was knowledge asleep at the moment of action; Augustine's divided will is darker — the will itself wounded, wanting and not wanting in one breath. He generalized the wound: original sin, the doctrine that humanity inherits a damaged will from its first parents and cannot heal itself. The cure must come from outside: grace, God's unmerited help.

Enter Pelagius, an austere British monk: God commands nothing impossible; we can obey by effort. In Rome he heard a bishop quote one sentence of Augustine's and was scandalized:

Give what Thou enjoinest, and enjoin what Thou wilt.

— Augustine, Confessions 10.29 (trans. E. B. Pusey)

To Pelagius this dissolved morality into waiting for divine assistance. To Augustine it was honesty about the fig tree: effort itself was the broken instrument. Augustine won; councils condemned Pelagianism. But the victory has a hard edge he refused to file down: if grace alone saves and not all are saved, God chooses. This is predestination — God's selection, before time and on no merit, of whom to rescue from the massa damnata, the "condemned mass" of humanity; unbaptized infants, on his mature view, included. Many heirs softened that. Augustine never did.

What, Then, Is Time?

The Confessions ends strangely: autobiography dissolves into philosophy. Hecklers asked what God was doing before creation; he reports the stock joke — preparing hell for people who ask — and declines it (11.12). His serious answer: there is no "before"; time is a creature, made with the world. Which exposes a question never asked so nakedly:

What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not.

— Augustine, Confessions 11.14 (trans. E. B. Pusey)

The past no longer exists, the future does not yet, and the present is a durationless knife-edge — so what are we measuring when we measure time? Something in the mind, he proposes. Memory holds the past present, attention the now, expectation the future: recite a psalm and feel expectation drain through attention into memory. Time is a distension of the soul — the mind stretched across what is not yet and what no longer is. Whether this answers the physicist or changes the subject is still debated; Husserl's analyses of time-consciousness begin here (Lesson 43). Book 10 had already toured "the fields and spacious palaces of my memory" (10.8, trans. Pusey) — an interior vast enough to hold images, skills, moods, and somehow God. Greek philosophy aimed its wonder at the cosmos; Augustine aimed it inward, and found a wilderness.

The Two Cities

The sack of Rome demanded a public answer; from 413 to 426 Augustine wrote it. City of God begins as polemic — Rome suffered worse under the old gods, thank you — and grows into the first philosophy of history: what the whole human story means.

Two cities have been formed by two loves: the earthly by the love of self, even to the contempt of God; the heavenly by the love of God, even to the contempt of self.

— Augustine, City of God 14.28 (trans. Marcus Dods)

The cities are not places or institutions but invisible communities defined by their ultimate loves, their members mingled in every nation and congregation — the church included — until history's end sorts them. The payoff cuts both ways. Against Rome's worshippers: no empire is eternal, no state sacred, no earthly politics final. Against despair: earthly peace is a real good, and the heavenly city's pilgrims should be decent citizens of the earthly one meanwhile. Every later Western quarrel over church and state — and much political realism about what power can deliver — starts on this page.

The Honest Reckoning

Now the part admirers skip. North African Christianity was split by the Donatist schism, a rival church born in the persecution years, holding that clergy who had surrendered Scriptures to Diocletian's police could not validly baptize or ordain. Augustine argued with them for years; then imperial coercion — fines, confiscations — succeeded where argument had not, and he talked himself into blessing it. His proof-text was the parable of the banquet, Luke 14:23: "compel them to come in." A father, he reasoned, may drag his son from a burning house; the church may school her wayward children through fear (Letters 93, 185). He opposed executing them. But the principle now bore the greatest name in Latin Christianity, and for a millennium persecutors — medieval inquisitors among them — cited it on his authority. The bitter irony: this is the man who had written that "no one can believe unless he is willing" (Tractates on John 26.2, our close rendering). Add the late predestinarian hardening — the condemned mass, the infants — and the pattern of the concubine's dismissal recurs at world scale: antiquity's most honest self-examiner could still make other people pay for his certainties. An honest course says so.

Legacy: Who Listened

In the Latin West "the Philosopher" would eventually mean Aristotle — but for eight centuries the authority, cited like Scripture's younger brother, was Augustine. Boethius transmits him; Anselm's motto "faith seeking understanding" is crede ut intelligas under new management (Lesson 12); Aquinas quotes him on nearly every page while rebuilding theology on Aristotle (Lesson 17). When an Augustinian monk named Martin Luther radicalized the grace doctrine, the Reformation followed (Lesson 19) — Europe's wars of religion were, among other things, a custody battle over Augustine.

The philosophical afterlives run as long. Si fallor, sum becomes Descartes' cogito (Lesson 21). Evil-as-privation passes to Leibniz, whose technical name for the defense of God waits for Lesson 24. The confessional turn inward founds a genre: Rousseau lifts the very title for his defiantly unrepentant Confessions (Lesson 27), and Kierkegaard's passionate subjectivity is Augustinian to the bone (Lesson 32). Wittgenstein opens the Philosophical Investigations by quoting the Confessions' picture of how a child learns words (Lesson 38). Husserl builds on Book 11's time analysis (Lesson 43). Hannah Arendt wrote her doctoral dissertation on Augustine's concept of love (Lesson 46). And the two cities frame every later argument about religion and state power.

Within fifty years of his death the Western empire was gone; but his library survived the siege, and his books carried antiquity across the wreckage into the worlds we visit next — Baghdad, Córdoba, Paris. The Great Conversation was about to learn Arabic.

Reflection Questions

  1. Augustine's diagnosis is that all human restlessness is God-hunger misaddressed. Is that a deep insight or an unfalsifiable move? What experience, if any, could count against it?
  2. Replay the Pelagian controversy over a habit you have actually tried to change. Whose picture of the will fits your evidence better: effort that suffices, or a divided will needing help from outside?
  3. "No earthly politics is final." Is that healthy realism, or a license for quietism in the face of injustice — and what does your answer depend on?

Self-Check Quiz

  1. Why did the young Augustine find Manichaeism intellectually attractive?

    • A. Its two eternal powers took evil off God's hands: an all-good God is not responsible for what He is still fighting
    • B. It denied that evil exists at all, teaching that it is an illusion of the senses that the wise can learn to see through
    • C. It taught that evil is a privation of good, a lack of being in things that are in themselves good
    • D. It explained evil as the punishment of souls for sins committed in a former life, to be worked off through rebirth
  2. This lesson calls si fallor, sum and Descartes' cogito the "same step, different staircase." The difference is that:

    • A. Augustine reached the certainty by logical deduction from first principles, while Descartes reached it by a direct intuition that needs no inference
    • B. For Augustine the certain self is a rung toward the unchanging Truth above the mind; for Descartes it is a foundation for rebuilding knowledge and science
    • C. Augustine extended the certainty to the body and the senses as well as the mind, while Descartes confined it to the mind
    • D. Augustine meant it to refute the skeptics, who had doubted the senses, while Descartes meant it to refute the materialists, who had denied the soul
  3. Evil-as-privation tells us what evil is. Why does Augustine still need free choice to complete his answer to the problem of evil?

  4. Why did "Give what Thou enjoinest, and enjoin what Thou wilt" scandalize Pelagius — and what experience of Augustine's own made him stand by the sentence?

  5. Aristotle (Lesson 7) named the experience of knowing the better and doing the worse akrasia — knowledge present but inactive, like a drunk reciting verses he does not mean. How does Augustine's fig-tree account of the "two wills" diagnose the same experience differently?

Show answers
  1. A — Manichaeism solves the problem of evil by denying omnipotence, not goodness: evil flows from an independent power of Darkness, so God is off the hook. (C is the Plotinian view Augustine adopted after leaving the Manichaeans.)
  2. B — The inference is the same; the destination differs. Augustine uses the certainty of self to ascend toward God; Descartes uses it as the foundation stone for a rebuilt edifice of knowledge, science included.
  3. Privation explains evil's status — a lack rather than a substance, so God created no evil thing — but not its origin: holes must be dug. Free choice, the will turning from greater goods to lesser, supplies the origin of moral evil without positing a second eternal power.
  4. Pelagius heard moral responsibility dissolving: if even obedience must be given by God, commanding it seems pointless, and effort becomes waiting. Augustine stood by it because of the garden: he had commanded his own will and it refused — effort itself was the broken instrument, so the help (grace) must come from outside.
  5. For Aristotle the fault is cognitive — knowledge temporarily inactive, while the will itself is not in question. For Augustine the will itself is divided, wanting and not wanting in the same breath; the failure is not a lapse of attention but a wound in willing, which is why he concludes that knowledge alone cannot cure it.
