I sat down with philosopher and author Peter Boghossian to wrestle with one of the defining questions of modern American life: Can human rights, equality, and morality be justified without a belief in God? As a Catholic, I’ve come to see our 21st-century social breakdown as largely the result of secularization. Without a broadly Christian cultural foundation, the classical liberal approach to government might not work. Peter, who shares many of my classical liberal values, takes the opposite stance—that morality can be grounded in secular reason. We had a great conversation and took it as deep as we could in just two hours: atheist vs. Christian, but more importantly, friend to friend.
