The Nature and Destiny of Man issues a vigorous challenge to Western civilization to understand its roots in the faith of the Bible, particularly in the Hebraic tradition. Niebuhr here lays out his influential understanding of the two poles of human existence: finitude and freedom. Individual human thriving requires that we fully understand and honor both of these aspects of our nature, yet human history demonstrates our penchant for placing one over the other. This book is arguably Reinhold Niebuhr’s most important work. It offers a sustained articulation of Niebuhr’s theological ethics and is considered a landmark in twentieth-century thought.
