“Starting out, I imagined a straightforward book in three parts, moving along a taut narrative path with a sturdy foundation of clay undergirding all. Books have their own fates, however, and research—at least the kind of research that I practice—yields to serendipity. If the destination is known beforehand, what’s the point of the journey? A provisional map of the whole allows the woolgathering pilgrim to get a little lost along the way without losing his bearings completely. Meanwhile, coincidences and chance meetings confirm a certain rightness, a fit, in the meandering quest.”
