In Determined, Robert M. Sapolsky challenges one of the fundamental assumptions of human existence—free will. Drawing from decades of research in neuroscience, psychology, and behavioral biology, Sapolsky argues that every decision we make is the inevitable result of biological and environmental factors beyond our control. From genetics and hormones to past experiences and social influences, he presents a compelling case that our sense of agency is an illusion. Yet, rather than leading to nihilism, this realization, he suggests, can foster greater empathy, compassion, and a rethinking of societal structures like justice and morality.
