In this vivid book, the historian Steven Stoll considers the way people throughout the Atlantic world read wealth into nature during the 1830s and 1840s. Opening among the supersized products and high-stacked shelves of Costco, The Great Delusion weaves past and present together through the life of a strange and brooding German engineer and technological utopian named John Adolphus Etzler, who pursued universal wealth from the inexhaustible forces of nature: wind, water, and sunlight. He was not a major theorist. He did not invent anything we use today. But Etzler absorbed and articulated just about every major materialist idea of the time, using those theories to pursue his own program for abundance and happiness. In Etzler we see a disturbing picture of ourselves. If he seems eccentric—or just plain crazy—he was no less so than the most pragmatic thinkers of his time, and of ours. Eloquent and insightful, The Great Delusion neatly demonstrates that Etzler’s fantasy has become our reality and that we continue to live by some of the same economic assumptions that he embraced.
