How could poetry and literature have arisen from something as plebian as the cuneiform equivalent of grocery-store bar codes? I prefer the version in which Prometheus brought writing to man from the gods. But then I remind myself that...we should not be too fastidious about where great ideas come from. Ultimately, they all come from a wrinkled organ that at its healthiest has the color and consistency of toothpaste, and in the end only withers and dies.
