One of the world’s greatest scientists of human behaviour, the bestselling author of Behave, shows that free will does not exist - and sets out the disturbing yet liberating implications of accepting this fact. ‘One of the best scientist-writers of our time’ OLIVER SACKSWhat if free will is an illusion? As Robert Sapolsky shows in this masterful account of the science of human behaviour, 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.

‘A joy to read. It's impossible to recommend this book too highly.
