I was sitting on the train one day chipping away at William T. Vollmann’s latest slab of obsessional nonfiction when my friend Tsia, who incidentally is not an underage Thai street whore, offered to save me time with a blurby one-sentence review based entirely on the book’s cover and my synopsis of its first 50 pages. “Just write that it’s like Robert Caro’s The Power Broker,” she said, “but with the attitude of Mike Davis’s City of Quartz.” This struck me as good advice, and I was all set to take it, but as I worked my way through the book’s final 1,250 pages, I found I had to modify it, slightly, to read as follows: Imperial is like Robert Caro’s The Power Broker with the attitude of Mike Davis’s City of Quartz, if Robert Caro had been raised in an abandoned grain silo by a band of feral raccoons, and if Mike Davis were the communications director of a heavily armed libertarian survivalist cult, and if the two of them had somehow managed to stitch John McPhee’s cortex onto the brain of a Gila monster, which they then sent to the Mexican border to conduct ten years of immersive research, and also if they wrote the entire manuscript on dried banana leaves with a toucan beak dipped in hobo blood, and then the book was line-edited during a 36-hour peyote seance by the ghosts of John Steinbeck, Jack London, and Sinclair Lewis, with 200 pages of endnotes faxed over by Henry David Thoreau’s great-great-great-great grandson from a concrete bunker under a toxic pond behind a maquiladora, and if at the last minute Herman Melville threw up all over the manuscript, rendering it illegible, so it had to be re-created from memory by a community-theater actor doing his best impression of Jack Kerouac. With photographs by Dorothea Lange. (Viking has my full blessing to use that as a blurb.)

The ship spotters do not respond to the objects of their enthusiasm with particular imagination. They traffic in statistics. Their energies are focused on logging dates and shipping speeds, recording turbine numbers and shaft lengths. They behave like a man who has fallen deeply in love and asks his companion if he might act on his emotions by measuring the distance between her elbow and her shoulder blade. But in converting a passion into a set of facts, the spotters are at least following a pattern with an established pedigree, most noticeable in academia, where an art historian, on being stirred to tears by the tenderness and serenity he detects in a work by a fourteenth-century Florentine painter, may end up writing a monograph, as irreproachable as it is bloodless, on the history of paint manufacture in the age of Giotto. It seems easier to respond to our enthusiasms by trading facts than by investigating the more naive question of how and why we have been moved.

They inspired this book, which the author hopes might function a little like one of those eighteenth-century cityscapes which show us people at work from the quayside to the temple, the parliament to the counting house, panoramas like those of Canaletto in which, within a single giant frame, one can witness dockers unloading crates, merchants bargaining in the main square, bakers before their overs, women sewing at their windows and councils of ministers assembled in a palace—inclusive scenes which serve to remind us of the place which work accords to each of us within the human hive. I was inspired by the men at the pier to attempt a hymn to the intelligence, peculiarity, beauty and horror of the modern work place and, not least, its extraordinary claim to be able to provide us, alongside love, with the principal source of life’s meaning.
