"Sapiens" showed us where we came from. "Homo Deus" looked to the future. "21 Lessons for the 21st Century" explores the present. In this new book, Harari helps us to grapple with a world that is increasingly hard to comprehend. How can we protect ourselves from nuclear war, ecological cataclysms and technological disruptions? What can we do about the epidemic of fake news? Which civilization dominates the world – the West, China, Islam? What can we do about terrorism?

With his trademark clarity and vision, Harari takes us on a thrilling journey into today’s most urgent issues as well as turning to more individual concerns. The golden thread running through this exhilarating new book is the challenge of maintaining our focus and attention in the face of constant and destabilising change. Ultimately what we and our children will need is mental stability, compassion, resilience and reason. This is a crucial part of our ongoing education in the 21st Century.
