I was looking for a biography of Sinclair Lewis. This book has a short bio at the beginning. Most of this book is summaries of Lewis' work and criticism of his work in historical context.
“At the end of (Elmer Gantry), Elmer is on bended knee, praying, ‘We shall yet make these United States a moral nation!’ The irony in Elmer’s last statement underscores the immorality of the kind of enforced morality Elmer has in mind. It also underscores what Lewis saw as one of the greatest dangers in American society—the tendency toward excess not only in religion but also in production, consumption, patriotism, and the proliferation of institutions.”, p. 53
