Thomas Cahill Quote

No longer did philosophers aspire to the deep spiritual insights and broad moral vision of Socrates, Plato, and Aristotle. They divided into conflicting schools and wandered through the Greco-Roman world as permanent immigrants, picking up tutoring jobs as they could.... the upshot was a debased intellectual climate, fragmented and agnostic.
