Todd Davis: Kurt Vonnegut's Crusade
Davis, Todd. Kurt Vonnegut's Crusade: Or, How a Postmodern Harlequin Preached a New Kind of Humanism (Albany, NY: State University of New York Press, 2006)
Considering the brevity of Kurt Vonnegut's Crusade, Todd Davis spends far too much time (approximately the first fifth of the book) discussing Jean-François Lyotard and postmodernism, leaving scant space for his analyses of Vonnegut's novels.
Davis takes this observation
At the center of postmodern humanism is the assertion that life is precious and that every attempt should be made to improve the condition of our planet in order to preserve life. (p. 138)
and applies it to Vonnegut's work. It's an interesting book, and one which I will likely revisit after reading more of Vonnegut's novels; as yet, I've only read Slaughterhouse-Five and Cat's Cradle.
