One of the theological classics of the twentieth century, Niebuhr's Moral Man and Immoral Society argues that using moral persuasion and shaming to affect the behavior of such collectives as corporations and nation states is fruitless, as these groups will inevitably seek to promote only their self-interest. He calls for a realistic assessment of group behavior and enumerates how individual morality can mitigate social immorality. This edition includes a foreword by Cornel West that explores the continued interest in Niebuhr's thought and its contemporary relevance.
