Without question A Canticle for Leibowitz is a most remarkable novel. The style is sharp, exact, completely individual, and above all alive. And the scale is huge—embracing life present, life past, and life future. Mr. Miller looks at life from the different angles of God and scientists and poets and priests and the Wandering Jew and—believe it or not—he makes sense out of it, and beauty too. Some critics have talked about this astonishing novel in terms of science fiction. That is an insult. Primarily and essentially it is religious and human.
