Michael Kammen's A Machine that Would Go of Itself: The Constitution in American Culture provides some interesting insights into the U.S. constitution as perceived through history. He traces how the constitution was viewed not by Supreme Court justices but rather by the thinkers and opinion leaders of the day. In one interesting example, he notes that earlier commentators referred to the constitution as a machine that fueled economic progress, but during the early 20th century progressives began to refer to it as a living, evolving organism. Of course, each had their own political motives for using those metaphors.Despite the insights, the book seems almost incomplete. First, it has a relatively heavy emphasis on the 19th century, virtually ignoring the constitution in U.S. culture during the crucial 50s and 60s. Second, Kammen's sources are primarily books and articles by elites, not the masses. This is sometimes a critical distinction, as during the 1960s when many people thought the constitution was too light on crime. Given this, the book reads more like a tome on U.S. constitutional culture and political theory rather than one focused on American culture.Recommended for scholars of American or comparative constitutions.
