Book excerpt: Exploring this theme, Robinson examines Plato's Ion, Philo Judaeus and Augustine on the Septuagint, Paul on inspired interpreters, Joseph Smith on the Book of Mormon, and Schleiermacher, Marx, and Heidegger on translation. He traces the imaginative and historical linkages between twentieth-century conceptions of ideology and ancient conceptions of spirit-channeling, and the performative inversion of power relations by which the "channel" (or translator) comes to wield the source author as his or her tool.
