In his book, “The Unintended Reformation: How a Religious Revolution Secularized Society,” Notre Dame History Professor Brad Gregory shows how the unsolved doctrinal disagreements and religious and political conflicts of 16th- and 17th-century Europe continue to influence American political, social, intellectual, and economic life today. He asks what propelled the West into a trajectory of pluralism, polarization and consumerism, and finds answers deep in our medieval Christian past. Brad Gregory, a USU alumnus, returns to Logan to give a presentation in the Tanner Talks series from the USU College of Humanities and Social Sciences. The talk is Friday at noon in USU Library room 101.
