Augustine

Augustine of Hippo (354-430 CE) is the bridge from antiquity to the medieval West. He wrote in late Roman North Africa as the empire visibly cracked: *The City of God* was prompted by the Visigothic sack of Rome in 410. His work shaped Christian theology, Western political thought, and the philosophical psychology of the inner life for over a thousand years.

The *Confessions* (c. 397-400) is the first real autobiography, and arguably still the best. Augustine traces his own life from infancy through his Manichean phase, his Neoplatonist phase, his sexual restlessness, his conversion in a Milan garden, and his subsequent work as bishop of Hippo. The book is addressed to God throughout — it's prayer and philosophy simultaneously. The famous bits — the stolen pears, "Lord, make me chaste, but not yet," the meditation on time in Book XI — are embedded in a continuous theological project.

*The City of God* (begun 413, finished 426) is the big political-theological work. Two cities run through history: the City of God (oriented toward divine love) and the City of Man (oriented toward self-love). Earthly empires belong to the latter; their rise and fall are not the providential story. This was a serious challenge to the Constantinian fusion of empire and church, and it gave medieval Christianity a way to think about politics that wasn't simply imperial cheerleading.

The philosophical anthropology is dark. Original sin, the deeply broken will, the inability to do good without grace — these are Augustinian innovations that Catholic, Lutheran, Calvinist, and Jansenist traditions would all draw on. The philosophy of time (the past exists in memory, the future in expectation, the present is a knife-edge) anticipated Husserl. The interior turn — taking introspection itself as the route to truth — anticipated Descartes by twelve centuries.
