Robert M. Sapolsky, a Stanford neurobiologist and MacArthur “genius” fellow, challenges our deeply ingrained beliefs about free will. Building on his seminal 2017 work “Behave,” which explored the dynamics of nature and nurture, Sapolsky’s latest book, “Determined: A Science of Life Without Free Will,” suggests that science, medicine, and philosophy may actually support determinism over free will. As societal discourse increasingly embraces a culture of victimhood, he questions the quintessentially Californian belief in personal agency.
