What if free will is an illusion? In Determined one of the world’s greatest scientists of human behaviour overturns one of our most powerful beliefs – that we are the authors of our own actions – and sets out the disturbing yet liberating implications of accepting this fact.

As Robert Sapolsky shows, everything we think and do is caused by the luck of our biology and the influence of our environment, and ultimately both are beyond our control. In a world without free will, we must completely rethink what we mean by choice, responsibility, morality and justice. Sapolsky’s extraordinary book does exactly this, guiding us toward a profoundly fairer, more humane way of living together.
