How to Change the World: Social Entrepeneurs and the Power of New Ideas, by David Bornstein revolves around Bill Drayton:

James O’Toole, an expert in management and leadership, observes that great thinkers throughout the world agree that “groups resist change with all the vigor of antibodies attacking an intruding virus.” O’Toole examines a number of cases in which a potentially beneficial institutional change was resisted and finds that the resistance occurs when a group perceives that a change in question will challenge its “power, prestige, and satisfaction with who they are, what they believe, and what they cherish.” He asserts: “The major factor in our resistance to change is the desire not to have the will of others forced on us.”
