“The mindset of antiquity lacked economic science and sociological theory. The ancients did rather well with political narrative, although, except for Thucydides, no first-rate political annalist and analyst emerged from the literary populace. But the ancients never showed a capacity, or even an inclination, to examine closely the urban world they themselves inhabited."Neither, however, was the medieval world in the 500s through the 1500s, which succeeded antiquity, much better at economics and sociology. It was only in the eighteenth and early nineteenth centuries that this kind of thinking emerged with Adam Smith and Alexis de Tocqueville in response to industrial and political revolutions."What interested the urban dwellers of antiquity were the gods. During the Hellenistic and Roman eras the theoretical capacity of the literate urban population was given over to thinking about the nature of divinity. The chief theological formats were polytheism (many gods); monotheism (one god); dualism (two dogs, one good, the other evil); and dying and reborn savior gods that could also be fitted into the other three categories of divinity.”

“The classical heritage as shaped by and filtered through Roman culture had two great flaws. First, it prevented the very rich oral cultures of the ancient Mediterranean from surviving from antiquity into later times. All that was left as creative forces were Greek philosophy and Roman law. These were very substantial cultures but they represented a great narrowing of what could be passed on from antiquity to later centuries..."Second, another deficiency of classical culture was its lack of social conscience, its obliviousness to the slavery, poverty, disease, and everyday cruelty endured by more than half of the fifty million people who inhabited the empire. The classical heritage represented a narrow and insensitive social and political theory reinforcing a miserably class-ridden and technologically stagnant society.”

“The Gnostics (also called Manichees) postulated that there were two gods -- the Christian God of goodness and light, and an evil anti-God of darkness. This theory proved an easy explanation of why there was evil in the world. It was rejected by Catholic Christianity in favor of the monotheistic view that there was one God who created only goodness. Evil was sin, a rebellious falling-away from God, a perversion of His goodness. This was the foundation of the evolving Christian concept of Satan.”

“Saint Augustine proliferated central theological and political doctrines of the Church, following Saint Paul closely. History is the scene of the struggle between the Heavenly and Earthly Cities, but only God before the Last Judgment knows the membership rolls. Human nature is so sinful (rebellious and corrupt) that only those who have received grace, i.e., have been chosen by God to love Him, can be saved for eternal life. This theory caused a lot of trouble for the medieval church, which by and large abandoned it. It was revived much later by Martin Luther."By the early fifth century, at a series of church councils, the Christians had hammered out a compromise theory of the Trinity -- God the Father, the Son, and the Holy Spirit (Church) -- more or less of one substance but with three personalities. Those who would not accept this compromise were branded as heretics and sooner or later persecuted by the imperial state.”

“The end of Egypt's isolation turned what had been only occasional and incidental contact with the rest of the Near East into a constant and significant exchange of goods and ideas. The new cosmopolitanism introduced new forms and motifs and a growing naturalism to art. Egypt had always been receptive to immigrants, who had easily been assimilated into its culture; now even the pharaohs could marry foreigners. In addition, the increase of commerce and the emergence of a cosmopolitan urban population -- at Thebes and other cities -- marked the first real urbanization in Egyptian society.”

“The ultimate triumph of Christianity was aided by the internal drive within Roman paganism toward some kind of monotheism. By 150 A.D., whatever vitality had once existed in ancient polytheism had mostly declined, and the gods played little or no role in individual lives. The state temples to the old gods became civic centers rather than religious entities."But paganism went about reforming itself. It drew upon the Alexandrian mystical form of Platonism, taught by Plotinus -- what we call Neoplatonism -- to conjure an image of the deity as a single spiritual fountain of life that fructifies the world."This Neoplatonic monotheism became popular in aristocratic circles in fourth-century Rome and gave such renewed vitality to paganism that the triumph of Christianity had to be bolstered by state proscription of this latter-day monotheistic paganism. By 390, Roman paganism was almost as close to monotheism as was Christianity.”

“When historians and literary scholars talk about the classical heritage, or the legacy to Western civilization from antiquity, they are primarily thinking of four worldviews that were written in Hebrew or Greek among the body of religious, philosophical, and literary texts created before 250 B.C. These are the Hebrew Bible, the philosophies of Plato and Aristotle, and Hellenistic, or Alexandrine, literature.”
