Body scans at the airport, bikini pics on Facebook, a Twitter account for your stray thoughts, and a surveillance camera on every street corner - today we have an audience for all of the extraordinary and banal events of our lives. The threshold between privacy and disclosure becomes more permeable by the minute. But what happens to our private selves - indeed, the people who we truly are - when our public personas are left on? In this brilliant, penetrating addition to the Big Ideas/Small Books series, Garret Keizer considers the moral dimensions of privacy in relation to choice and equality. Choice not only protects us from violation but also allows social intercourse to be dignified, beautiful, and interesting. At the same time, privacy is most voluntary between persons of equivalent power. In Privacy, Keizer considers the evolution of the quintessentially American struggle to achieve it, which - along with the battles liberty and justice for all - has done much to define our recent history. From Greek and Elizabethan dramas to the histories of the ballot box, the love letter and the immense, overcrowded confessional of the Internet, he examines our ever-changing notions of privacy, all the while asking this central question: If we endanger privacy, do we not also threaten the fundamental nature of human relationships, our will to freely guard and reveal ourselves?
