While it can be a little dry and overly synthetic of others' work at points, Lynn Dumenil's "The Modern Temper" is at its core a strong portrait of the 1920s. She shows how a sense of haltering tension—progress mixed with regression, tradition, and backlash—characterized cultural changes in the arts, social sciences, politics, and religion. I liked the book's kaleidoscopic narrative and emphasis on historical continuities dating back to the Progressive Era. WWI was a generation-shaping event, yes, but there was more to America in the 1920s than disillusionment that turned into hedonism. There were modernist artists duking it out in the press with Southern agrarians, biologists debating creationists, ascendant conservatives fretting about the place of individual autonomy while the last few Progressives tried in vain for reform, and other cultural tensions that predated WWI. I'd have loved some footnotes, but they were sacrificed to the God that is Popular Press Publication. The book's readability makes it useful for college seminars.
