This episode is with Kevin Mitchell. He is an associate professor of Genetics and Neuroscience at Trinity College Dublin, where he investigates how genetic variations influence neural wiring, cognition, and conditions like autism and schizophrenia. Kevin is also the author of Innate: How the Wiring of Our Brains Shapes Who We Are and Free Agents: How Evolution Gave Us Free Will. Here, we discuss the laws of biology and the nature of free will. Kevin also shares insights on agency as a defining feature of life, the meaning of self, and the evolution of perception.
