To explore this provocative topic in depth, scholars and practitioners gathered at Harvard on March 11–12, 2004 for Misuses of Power: Causes and Corrections, sponsored by the Center for Public Leadership and the Hauser Center for Nonprofit Organizations. Throughout the two days of discussion, the conference heeded the wisdom of John F. Kennedy, who spoke the following words at Amherst College in 1963: “The men who create power make an indispensable contribution to the nation’s greatness. But the men who question power make a contribution that is just as indispensable, for they determine whether we use power or power uses us.”
