The powers of political secrecy and social spectacle have been taken to surreal extremes recently. Witness the twin terrors of a president who refuses to disclose dealings with foreign powers while the private data of ordinary citizens is stolen and marketed in order to manipulate consumer preferences and voting outcomes. We have become accustomed to thinking about secrecy in political terms and personal privacy terms. In this bracing, new work, Hugh Urban wants us to focus these same powers of observation on the role of secrecy in religion.With Secrecy, Urban investigates several revealing instances of the power of secrecy in religion, including nineteenth-century Scottish Rite Freemasonry, the sexual magic of a Russian-born Parisian mystic; the white supremacist BruderSchweigen or "Silent Brotherhood" movement of the 1980s, the Five Percenters, and the Church of Scientology. An electrifying read, Secrecy is the culmination of decades of Urban's reflections on a vexed, ever-present subject.
