Albert Einstein remains renowned around the world for revolutionizing our understanding of the cosmos, but very few realize that the celebrated scientist had a deep spiritual side. Einstein believed that one wondrous force was woven through all things everywhere—and this sense of the pervasive sacred influenced every aspect of his existence, from his marvelous science to his passionate pacifism.

Outside of the academics and activists whose ideology came to dominate the West in the second decade of the twenty-first century, arguably no group influenced public discourse as much as the Intellectual Dark Web.

Challenging the intellectual and cultural orthodoxies that engulfed universities, the media, and big tech, this group—a loose collective of politically diverse intellectuals, commentators, and scholars critical of political correctness, identity politics, and cancel culture—relied on alternative platforms like podcasts, digital magazines, and YouTube to promote free speech, universal rights, and individual liberty.

While the term is most commonly identified with Sam Harris, Ben Shapiro, Jordan Peterson, Bret and Eric Weinstein, and Joe Rogan, the group’s concerns and philosophy extended more broadly to include a wide range of individuals who helped mainstream critiques of “woke” culture and a robust defense of free speech, including Steven Pinker, Michael Shermer, Jonathan Haidt, Dave Rubin, Ayaan Hirsi Ali, and Stephen Fry.

The Intellectual Dark Web’s coherence began to unravel in the early 2020s due to internal differences (such as over the response to COVID-19 and climate change), and its full legacy and historical impact are yet to be determined.

In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence.

Matt Ridley revisits Darwin’s revelatory theory of mate choice through the close study of the peculiar rituals of birds, and considers how this mating process complicates our own view of human evolution.

Ridley also explores the scientific research into the evolution of bright colors, exotic ornaments, and elaborate displays in birds around the world. Charles Darwin thought the purpose of such displays was to “charm” females. Though Darwin’s theory was initially dismissed and buried for decades, recent scientific research has proven him newly right—there is a powerful evolutionary force quite distinct from natural selection: mate choice. In Birds, Sex and Beauty, Ridley reopens the history of Darwin’s vexed theory, laying bare a century of disagreement about an idea so powerful, so weird, and so wonderful, we may have yet to fully understand its implications.

Matt Ridley is the bestselling author of The Rational Optimist and Viral: The Search for the Origin of COVID-19 (with Alina Chan). His books have sold over a million copies. Ridley served in the House of Lords from 2013 to 2021 and is a fellow of the Royal Society of Literature, the Academy of Medical Sciences, and an honorary member of the American Academy of Arts and Sciences. His latest book is Birds, Sex and Beauty: The Extraordinary Implications of Charles Darwin’s Strangest Idea.

Phil Tinline, author of the new book Ghosts of Iron Mountain, explores the origins of the infamous Report from Iron Mountain, its role in conspiracy culture, and its lasting influence on perceptions of the military-industrial complex. The conversation also examines Holocaust denial, nativism, and the evolution of deep state conspiracies, highlighting the power of narratives in shaping democracy and public trust.

Tinline is a British freelance writer and documentarian. His book The Death of Consensus: 100 Years of British Political Nightmares was named The Times (London) Politics Book of the Year. Over two decades at the BBC, he has produced and presented acclaimed documentaries on the impact of political history on contemporary life.

Michael and Katherine Stewart discuss the rise of religious nationalism in America, its impact on public education, and the broader implications for democracy. They explore the strategies employed by religious groups to infiltrate public schools, the culture wars surrounding education, and the divisive nature of the New Right.

Katherine Stewart is the author of The Power Worshippers: Inside the Dangerous Rise of Religious Nationalism, the award-winning book upon which the documentary feature, God & Country, produced by Rob Reiner, is based. She has covered the intersection of faith and politics for over 15 years. Her new book is Money, Lies, and God.

Michael Shermer and Jeff Sebo explore moral philosophy, focusing on animal rights, sentience, and consciousness. They discuss the definitions of morality, ethical pluralism, and the divide between consequentialism and deontology. The conversation examines who belongs in our moral circle, the ethics of insect farming, the future of animal agriculture, abortion, and whether advanced AI could be considered sentient beings or even co-citizens.

The guests today are co-authors of a new paper in Science Advances titled: “A reassessment of the ‘hard-steps’ model for the evolution of intelligent life.”

Jennifer Macalady is a Professor of Geosciences at the Pennsylvania State University. Her research is focused on microbial ecology and evolution, and interactions between microorganisms and Earth materials like minerals and water through geologic time.

Daniel B. Mills is a postdoctoral researcher in the Orsi Geomicrobiology Lab at The University of Munich in Germany. His research focuses on the co-evolutionary history of Earth's surface environment and eukaryotic life—a topic he approaches by studying modern marine organisms and environments. He also applies this research to the ongoing search for exoplanetary biosignatures and technosignatures.

Shermer, Mills, and Macalady discuss the Hard Steps model of the evolution of intelligent life, the Drake Equation, the Fermi Paradox, the Great Filter, and the Great Silence. They also cover the Rare Earth hypothesis, major transitions in evolution, the uniqueness of humans, and the search for biosignatures and technosignatures.
