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.

In 1656, a young Amsterdam merchant was excommunicated by his Portuguese-Jewish community in the harshest terms it had ever used. Baruch Spinoza was accused of unspecified “horrifying heresies,” but the precise reasons for his expulsion remain a mystery. When he published his Theological-Political Treatise in 1670, which was condemned as “the most atheistic book ever written,” he began to reveal to the world what his heresies may have been. Yet ever since the eighteenth century, most readers and scholars have assumed that Spinoza was a pantheist—even a “God-intoxicated man,” as the poet Novalis put it. After all, how could a person whose books are suffused with talk of God be an atheist? In Spinoza, Atheist (Princeton University Press, 2026), Steven Nadler, one of the world’s leading authorities on the philosopher, aims to settle the question and show that that’s exactly what he was.

Nadler makes a powerful case that there is no real divinity for Spinoza. God is Nature, and isn’t an object of worshipful awe or religious reverence but can only be understood through philosophy and science. There is nothing supernatural—no mystery, ineffability, or sublimity. Spinoza does speak of “blessedness” and “salvation,” but these, too, are to be understood in natural and rational terms, as the peace of mind and happiness that come from understanding ourselves and the world.

Whether Spinoza believed in God is a fascinating and enduring controversy. Spinoza, Atheist promises to transform our understanding of his views and to make clear just how radical a thinker he was and remains. 

Steven Nadler is Vilas Research Professor and the William H. Hay II Professor of Philosophy at the University of Wisconsin–Madison. His many books include Rembrandt’s Jews, which was a finalist for the Pulitzer Prize, Spinoza: A Life, Think Least of Death: Spinoza on How to Live and How to Die, and A Book Forged in Hell: Spinoza’s Scandalous Treatise and the Birth of the Secular Age.

Most of us today would assume that morality and ethics, being value propositions, are questions for inspired leaders, religious creeds, poets—in other words, for the humanities. But what if I told you that we can construct a system of ethics and morality by studying math—more specifically: the laws of thermodynamics? That’s what Professor Drew M Dalton argues in his latest book. Dalton traces a line of metaphysical inquiry from Kant through Spinoza, Nietzsche, and others up to today to show how we get from E=mc2 to a full-throated call to resist evil and alleviate suffering to our very last breath.

By overturning our assumptions about the nature and value of reality, The Matter of Evil: From Speculative Realism to Ethical Pessimism (Northwestern UP, 2024) presents a provocative new model of ethical responsibility that is both logically justifiable and scientifically sound. Dalton argues for “ethical pessimism,” a position previously marginalized in the West, as a means to cultivate an account of ethical responsibility and political activism that takes seriously the unbecoming of being and the moral horror of existence.

Drew M. Dalton is a professor of English at Indiana University, having received his Ph.D. in Philosophy from the University of Leuven in Belgium. His research focuses on the normative implications of different metaphysical systems and, specifically, he’s interested in how questions of right and wrong, good and evil, beauty and pleasure are framed within aesthetics, literary theory, ethics, and political philosophy. He is the author of Longing for the Other: Levinas and Metaphysical Desire (Duquesne University Press, 2009), The Ethics of Resistance: Tyranny of the Absolute (Bloomsbury, 2018), and The Matter of Evil: From Speculative Realism to Ethical Pessimism (Northwestern University Press, 2023).

In recent surveys, one in four Canadians say they have no religion. A century ago, Canada was widely considered to be a Christian nation, and the vast majority of Canadians claimed they were devoutly religious. But some were determined to resist. In the 1920s and ’30s, groups of militant unbelievers formed across Canada to push back against the dominance of religion.

Towards a Godless Dominion: Unbelief in Interwar Canada by Dr. Elliot B. Hanowski (McGill-Queen’s University Press, 2023), explores both anti-religious activism and the organized opposition unbelievers faced from Christian Canada during the interwar period. Despite Christianity’s prominence, anti-religious ideas were propagated by lectures in theatres, through newspapers, and out on the streets. Secularist groups in Montreal, Toronto, Winnipeg, and Vancouver actively tried to win people away from religious belief. Looking at interwar controversies around religion, Hanowski shows how unbelievers were able to use these conflicts to get their skeptical message across to the public. Challenging the stereotype of Canada as a tolerant, secular nation, Towards a Godless Dominion returns to a time when intolerant forms of Christianity ruled a country that was considered more religious than the United States.

Dr. Elliot Hanowski is an academic librarian at the University of Manitoba with a doctorate in Canadian history and one of the founders of the International Society for Historians of Atheism, Secularism, and Humanism. His research focuses specifically on the history of unbelief in Canada.

The open access Bloomsbury Handbook of Religion and Heritage in Contemporary Europe (Bloomsbury, 2025) offers readers a state-of-the-art guide to the public debates and scholarship on religious heritage in contemporary Europe. It contains articles by scholars, policy makers and heritage practitioners, who explore the key challenges facing the organizations, churches, and government bodies concerned with religion and heritage.

Featuring polemics, case studies, and analysis, the volume is united by major themes,
including Jewish, Muslim and Christian heritage, the (post)secular, interreligious heritage, sacred texts, museums, tourism, and contemporary art.

The book explores the shifting significance of Europe's historic churches, synagogues, and mosques, many of which are caught between declining numbers of worshippers, increasing numbers of tourists, and the pressure to find new uses. It also examines the key role religious heritage plays in political discourse, both in the interest of including and excluding religious minorities.

Growing up in Crown Heights, Brooklyn as a member of the Chabad-Lubavitch Hasidic Orthodox Jewish community, Zalman Newfield was raised in an atmosphere of strict gender segregation, rigorous religious education, and nearly all-consuming ritual practices. Trained to be a Lubavitch emissary, he traveled around the world doing Jewish outreach to help usher in the messianic redemption. However, after exposure to the wider world, he abandoned the faith of his youth.

Brooklyn Odyssey: My Journey Out of Hasidism (Temple University Press, 2026) is Newfield's poignant and hopeful memoir about exiting Orthodoxy. He recounts asserting his individuality and taking the radical step of shaving his beard. Reflective about his upbringing, Newfield is open to and curious about a world beyond Brooklyn while also maintaining his profound bond with his family and Jewish tradition. He writes candidly about his emotional, intellectual, and social experiences in and out of the Lubavitch community.

From pivotal moments of devastation, including the illness and death of his younger brother and of his revered spiritual leader Rabbi Menachem Mendel Schneerson, to moments of joyful resolve, including the decision to pursue a doctorate and marry a non-Orthodox Jew, Newfield takes readers on his moving and impactful journey.

Zalman Newfield is Associate Professor of Sociology and Jewish Studies at Hunter College, City University of New York and the author of Degrees of Separation: Identity Formation While Leaving Ultra-Orthodox Judaism (Temple). Visit him online at zalmannewfield.com.
