Dr. Guy Leschziner, a neurologist and bestselling author, dives into the complex interplay between biology and morality. He argues that our so-called 'sins' may have evolutionary roots rather than stemming purely from moral failings. The discussion reveals how genetics and environment shape our behavior, suggesting a more compassionate view of accountability. Leschziner also explores the implications for the criminal justice system and challenges the traditional notions of free will. Expect to ponder the fascinating connections between neuroscience and human ethics.

insights INSIGHT
Evolutionary Roots of Sins
Sins evolved as adaptive traits with evolutionary benefits, still relevant today.
Modern contexts create mismatches where these behaviours become maladaptive.
insights INSIGHT
Free Will Exists On Spectrum
Free will likely exists on a spectrum influenced by genetics, brain structure, and upbringing.
Absolute free will or no free will are oversimplifications of complex human nature.

In this episode, I speak with Professor Guy Leschziner, a consultant neurologist and author of three bestselling books, including: “The Man Who Tasted Words”, “The Secret World of Sleep”, and “The Seven Deadly Sins”, which this interview focuses on.
Drawing on insights from evolutionary biology, genetics, and clinical neurology, Guy makes a compelling case that what we label as “sin” may often have a biological cause, and isn’t necessarily a moral failing.
Expect to learn:
— Why our so-called “sins” evolved as adaptive traits—and why they still serve a purpose
— How free will may be more of a spectrum than a binary
— Why understanding the biology of behaviour could radically change the criminal justice system
— The disturbing story of Robert Alton Harris—and what it reveals about judgment, compassion, and accountability
And more.
