The book is structured around three major revolutions that have shaped our society: the Cognitive, Agricultural, and Scientific revolutions.

Harari challenges conventional historical narratives and explores how our capacity for belief, storytelling, and collective imagination has shaped civilizations. He examines how myths, money, and machine technology have built and altered social orders and moral systems.

A key focus of the book is the exploration of human happiness and suffering throughout history, questioning whether we are better off now than in past eras. Harari uses anthropological, psychological, and philosophical analysis to explore these themes.

The book encourages readers to think about the paths we’ve taken and those we’re yet to choose, providing profound insight into what it means to be human in a rapidly changing world.
