Does God exist? This straightforward question has spawned endless debate, ranging from apologists’ supposed proofs of God’s existence to New Atheist manifestos declaring belief in God a harmful delusion. In Disbelief: The Origins of Atheism in a Religious Species (Prometheus Books, 2024), Will M. Gervais, a global leader in the psychological study of atheism, shows that the ubiquity of religious belief and the peculiarities of atheism are connected pieces in the puzzle of human nature.

Through a firsthand account of breakthroughs in the scientific study of atheism, including key findings from cognitive science, cultural evolution, and evolutionary psychology, Disbelief forces a rethinking of the prevailing theories of religion and reminds both believers and atheists of the shared psychologies that set them on their distinct religious trajectories.

Having grown up in the mountains of Colorado, and going to school there and later in Vancouver, Will Gervais today is a Reader in Psychology in the Centre for Culture and Evolution, Brunel University London, and Programme Lead for Brunel’s Culture and Evolution MSc Programme.

A fascinating, behind-the-scenes look at non-religious funerals in contemporary London, An Honest Death: Life's End and Humanist Funerals (Princeton UP, 2026) is an intimate and moving ethnographic account of funerals for people who don’t believe in God or an afterlife. Focusing on secular funeral celebrants of the British Humanist Association (now called Humanists UK), the book examines how their ritual work is geared toward helping realize a secular world. There is a strong ethical commitment behind this effort, which is to face death with honesty based on the belief that this life is all we have. For the humanist celebrants and those they serve, this is what allows for a life with meaning and purpose. Written in a vivid style, the book centers on the lives and the funerals of particular people, from a three-year-old child to a man in his nineties. Anthropologist Matthew Engelke, who trained as a humanist celebrant as part of his research, describes how these officiants try to craft “sincere” funerals, avoiding language and music that might suggest that the person who died had any religious beliefs. The book also captures the highs and lows for humanist celebrants of working in the funeral business—a business that is, for many of them, a kind of vocational calling. Above all, An Honest Death draws out the tensions in secular humanist thought and practice between reason and the body, rationalism and materialism. Nothing matters more to the humanists than “daring to know” in the Enlightenment tradition, but nothing is so certainly known as the fact that we are finite and embodied creatures.

Matthew Engelke is professor and chair of the Department of Religion at Columbia University.

Today I'm speaking with Steven K. Green, Fred H. Paulus Professor of Law and Affiliated Professor of History and Religious Studies at Willamette University. We are discussing his book, American Infidelity: The Gilded Age Battle Over Freethought, Free Love, and Feminism (Oxford University Press, 2026). Since the first permanent Protestant settlement in Jamestown in 1607, Protestant Christianity has waxed and waned through a series of revivals, migrations, and challenges from alternative faiths like Catholicism and Mormonism. The Gilded Age, from roughly 1870 to 1900, was a unique period for Protestantism in American history. Most Americans still subscribed to a Protestant faith, though threats began to arise not from other confessions, but rather from philosophical and scientific challengers. The so-called freethinkers represented a broad range of beliefs and ideas, being united by a mutual skepticism of religious conservatism and traditional sexual and gender mores. American Infidelity tells the story of this tug-of-war for the soul of a nation, with Christianity on one side and the legacy of thinkers like Thomas Paine on the other.
