Socrates in the City Eric Metaxas and Jonathan Leaf: Decades of Chimp Propaganda
Apr 24, 2026
Jonathan Leaf, playwright and author of The Primate Myth, challenges the popular link between humans and apes. He traces cultural and scientific reasons for the chimp fascination. Short, punchy segments tackle media myths, violent chimp behavior, flaws in genetic comparisons, and why cooperation, language, and domestication set humans apart.

Chimpanzees Display Brutal Violence
- Leaf highlights extreme chimp violence and filial cannibalism as evidence they are not human-like.
- He cites Jane Goodall's observations of chimps eating infants and frequent deadly attacks, challenging popular tame portrayals.
Humans Fail Basic Primate Classification
- Leaf claims humans don't meet primate order definitions like prehensile feet and thus are misclassified.
- He notes we don't live in trees or eat tree leaves, undermining basic primate criteria.
The 98.6% Similarity Claim Is Misleading
- Leaf disputes the oft-cited 98.6% genetic similarity to chimps, calling the original studies flawed.
- He points to updated genomic work and a 123-author Nature study estimating 13.5–15% genetic difference.

Kinsey Reports
Alfred Kinsey
Wardell Pomeroy
Paul Gebhard
Clyde Martin
The Kinsey Reports, comprising *Sexual Behavior in the Human Male* (1948) and *Sexual Behavior in the Human Female* (1953), are groundbreaking studies on human sexuality conducted by Alfred Kinsey and his team.
These books were based on extensive interviews with thousands of individuals and presented data that challenged widespread beliefs about sexual behavior.
The reports introduced the Kinsey Scale, which described sexual behavior on a continuum rather than in binary terms.
The books were highly controversial due to their frank discussion of sexuality, but they are considered pioneering works that significantly influenced public perception and research in the field of human sexuality.

The Third Chimpanzee
The Evolution and Future of the Human Animal
Jared DIAMOND
María Corniero Fernández
In 'The Third Chimpanzee', Jared Diamond delves into the animal origins of human behavior, discussing how Homo sapiens came to dominate their closest relatives, such as chimpanzees.
The book argues that the dominance of certain human groups over others was not due to genetic superiority but rather to environmental advantages that allowed for larger populations, wider immunities to disease, and superior technologies for agriculture and warfare.
Diamond also explores topics such as sexual selection, language, art, and the potential for environmental degradation leading to extinction.
The book is divided into five parts, each addressing different aspects of human evolution and societal development.

Sex at Dawn
The Prehistoric Origins of Modern Sexuality
Christopher Ryan
Cacilda Jethá
In 'Sex at Dawn', Christopher Ryan and Cacilda Jethá present a compelling argument that human beings evolved in egalitarian groups where food, child care, and sexual partners were shared.
The authors use evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality to debunk the standard narrative of human sexual evolution.
They contend that before the advent of agriculture, human societies were characterized by sexual freedom and promiscuity, which strengthened social bonds and ensured the well-being of the group.
The book challenges modern concepts of monogamy and sexual exclusivity, offering a fresh perspective on human sexuality and its implications for modern relationships.

The Moral Animal
Why We Are the Way We Are
Robert Wright
In 'The Moral Animal', Robert Wright delves into the world of evolutionary psychology to explain human behavior, emotions, and moral conduct.
The book uses Charles Darwin's life and personal conduct in Victorian England as a case study to illustrate how evolutionary forces shape human behavior.
Wright discusses topics such as jealousy, altruism, and social class, arguing that many of our actions are driven by subconscious genetic strategies aimed at survival and the propagation of our genes.
The book also explores the paradox of how moral and responsible actions can emerge from a strictly Darwinian interpretation of human behavior, suggesting that understanding our evolutionary past can help us override our primitive programming and develop a more common moral outlook.

Das Kapital
Karl Marx
What is behind society’s obsession with monkeys? In this thought-provoking conversation, Socrates in the City host Eric Metaxas sits down with author and playwright Jonathan Leaf to explore the ideas behind his provocative new book, The Primate Myth, and to ask what lies beneath the persistent effort to connect humanity and primates. They discuss why this fascination has endured so powerfully across culture, science, and media.
From the mass popularity of Punch the Monkey to a broader cast of famous animals that have captured the public imagination, they examine the historical, cultural, and even political forces shaping this narrative, questioning whether the perceived relationship between humans and primates is grounded in genuine scientific insight or something more constructed. Along the way, they uncover surprising animal behaviors, trace unexpected ideological influences, and grapple with why this idea continues to resonate so strongly, inviting listeners to reconsider what they think they know about human origins, identity, and the stories we choose to believe.
