“The Irish are wild, feckless, and charming, or morose, repressed, and corrupt, but not especially civilized.”

Cahill suggests the Irish are an unlikely people to credit with “saving civilization” because of their supposed natural inclinations. Nevertheless, their work in copying surviving classical manuscripts served to preserve the remains of knowledge in the West after the Roman Empire fell apart.

“Without this Service of the Scribes, everything that happened subsequently would have been unthinkable. Without the Mission of the Irish Monks, who single-handedly re-founded European civilization throughout the continent in the bays and valleys of their exiles, the world that came after them would have been an entirely different one—a world without books.”

The monastic institutions became centers of learning and sites of further knowledge preservation. Cahill believes that were it not for these religious men and women’s efforts, the world’s history would be very different, and books would have entirely vanished. Of course, this claim is exaggerated, as Cahill equates the existence of books with classical texts in Christianized Europe and does not acknowledge manuscripts that existed in Asia, for example, or in Muslim Spain.

The Greeks were the first to use the term barbarian, in reference to their inability to understand the languages of others. To the Greeks, the languages sounded like “bar, bar, bar.
