Peter Irons is professor emeritus of political science at the University of California, San Diego. A noted constitutional scholar, historian, and lawyer, he is the author of the bestselling May It Please the Court; The Battle for the Constitution; War Powers: How the Imperial Presidency Hijacked the Constitution; and A People's History of the Supreme Court. His newest book is God on Trial: Dispatches from America's Religious Battlefields. In this conversation with D.J. Grothe, Peter Irons discusses the legal issues involved in the church-state court cases detailed in God on Trial, the personalities involved in the various cases and their motivations, and how religion can be so divisive in society. He also explores whether or not atheism is a civil rights issue, and what secularists and religious people alike may do to help secure separation of church and state in the United States.
