Book excerpt: Irving Babbitt (1865–1933) and Paul Elmer More (1864–1937) were the leading lights of the New Humanism, a consequential movement of literary and social criticism in America. Through their writings on literary, educational, cultural, religious, and political topics, they influenced countless important thinkers, such as T.S. Eliot, C.S. Lewis, Russell Kirk, Benedetto Croce, Werner Jaeger, and George Will. Their work became the source of heated public debates in the 1920s and early 1930s. The belligerent criticisms of Babbitt and More—composed by such famous intellectuals as Ernest Hemmingway and H.L. Mencken—have ensured that the New Humanism has seldom been properly appreciated. Humanistic Letters helps remedy this problem, by providing for the first time the extant correspondence of Babbitt and More, which gets to the heart of their intellectual project.
