Historians refer to several Great Awakenings throughout our country’s history. Recently PBS’s “God in America” highlighted these “Awakenings,” but did so in terms of broad, usually fervent evangelical movements. What about the metaphysical, mystical underpinnings of these movements? Have they been largely missed or skirted by historians? And what of Awakenings to follow? Christopher welcomes Mitch Horowitz, author of Occult America, to discuss the vital underpinnings of spiritual movements—and render insight on some American Awakenings of their own.
