Book excerpt: Abraham Lincoln's iconic phrase, 'the better angels of our nature', revealed his belief that the noblest qualities of humanity would heal a divided nation. In Frontiers in Spiritual Leadership, an interdisciplinary group of leading scholars from the University of Richmond explore these noble qualities and how leaders such as Lincoln make that expression possible. They review the landscape of spiritual leadership and the spiritual principles that are fundamental to effective and inspired leadership, emphasizing the values of love, forgiveness, purpose, trust, sacrifice, equality, and liberty, among others. Through an analysis of historical examples and contemporary issues, this book celebrates the many gifted and enlightened individuals whose leadership embodies the most exquisite qualities of humanity. It outlines the conceptual linkage between leadership and spirituality within groups and organizations and will appeal to students and scholars of leadership, ethics, religion, philosophy, psychology, and human growth potential.
