"This book by Reinhold Niebuhr's last graduate assistant allows us to watch Niebuhr grow, as his students did. Drawing extensively upon Niebuhr's own class notes, it is the best introduction yet to Niebuhr and his thought. A perfect way to celebrate the 100th anniversary of Niebuhr's birth."-Michael Novak, George Frederick Jewett Chair in Religion and Public Policy, American Enterprise Institute for Public Policy Research, Washington, D.C.
