The existence of free will - our ability to choose between one course of action and another, to determine our own destiny - is a foundation stone of Western society, dictating our notions of fairness and justice, punishment and reward, our very identity as individuals and humans. But as world-renowned scientist Robert Sapolsky shows, there is not a shred of evidence to suggest that free will exists, even while everything in our biology leads us to believe that it does.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

We are capable of savage acts of violence but also spectacular feats of kindness: is one side of our nature destined to win out over the other? Every act of human behaviour has multiple layers of causation, spiralling back seconds, minutes, hours, days, months, years, even centuries, right back to the dawn of time and the origins of our species. In the epic sweep of history, how does our biology affect the arc of war and peace, justice and persecution? How have our brains evolved alongside our cultures?

Discover this remarkable account of 21 years in remote Kenya with a troop of Savannah baboons from the New York Times best-selling author of Behave. Brooklyn-born Robert Sapolsky grew up wishing he could live in the primate diorama in the Museum of Natural History. At school he wrote fan letters to primatologists and even taught himself Swahili, all with the hope of one day joining his primate brethren in Africa. But when, at the age of 21, Sapolky's dream finally comes true, he discovers that the African bush bears little resemblance to the tranquillity of a museum. 

En la tradición de Jane Goodall y Dian Fossey, Robert Sapolsky, uno de los divulgadores científicos más reconocidos en la actualidad, cuenta la fascinante historia de cómo dejó las comodidades de la universidad para compartir durante más de dos décadas su trabajo de campo con una tropa de traviesos babuinos en la sabana africana. Sólo un joven idealista podía aterrizar en el corazón de Kenia esperando encontrar ahí una versión animada de lo que había visto y estudiado hasta entonces en el Museo de Ciencias Naturales de Nueva York.

Un examen minucioso del comportamiento humano y una respuesta a la pregunta: ¿por qué hacemos las cosas que hacemos? Sapolsky analiza los factores en juego, desde el momento previo hasta los factores arraigados en la historia de nuestra especie y su legado evolutivo. Partiendo de una explicación neurobiológica -¿qué sucedió en el cerebro de una persona un segundo antes de que se comportara así?, ¿qué visión, sonido u olor hicieron que el sistema nervioso produjera ese comportamiento?-, pasamos a pensar en el mundo sensorial y la endocrinología.
