The Call looks at the role of the spirit in the life and work of one of the most accomplished American peacebuilders of the 20th twentieth century, Robert Sargent Shriver (1915-2011), founder of the Peace Corps and architect of the War on Poverty. Author Jamie Price knew Shriver personally and served as the Founding Director of several programs dedicated to understanding and advancing Shriver's approach to leadership and peacebuilding. The Call is an imagined dialogue between Sargent Shriver and the character of Didymus about the role of the spirit in Shriver's efforts to build peace. Its title alludes to the pivotal moment when Shriver received the phone call from his brother-in-law, the newly-inaugurated President John F. Kennedy, asking him to be Director of the as-yet-nonexistent Peace Corps. This "true conversation that never happened", informed by Shriver's hundreds of speeches, philosophers and theologians who inspired him, and conversations between Shriver and the author, is an intimate, unique, often funny exchange about the inner workings of a mind always questioning the relationship between spirit and social action. A must-read for aspiring leaders, innovators, and peacebuilders seeking to redress contemporary challenges to human dignity and security, The Call invites readers to navigate conflict and nurture human connection with creativity and compassion.
