Most of Tocqueville’s letters from America, which were written between the spring of 1831 and February 1832, when he sailed for home, have never been published in English, but Frederick Brown, a biographer of Flaubert and Zola, has collected and translated them for a volume that Yale University Press is to release next year. A sample of the letters, roughly 20 percent of the whole, appears in the current issue of The Hudson Review, and they reveal a Tocqueville different from the one we know, or think we know, from “Democracy in America.”
