21 Lessons for the 21st Century

The bestselling phenomenon returns with 21 bite-sized lessons to help us understand our troubled times.


In twenty-one bite-sized lessons, Yuval Noah Harari explores what it means to be human in an age of bewilderment.

How can we protect ourselves from nuclear war, ecological cataclysms and technological disruptions? What can we do about the epidemic of fake news or the threat of terrorism? What should we teach our children?

Yuval Noah Harari takes us on a thrilling journey through today’s most urgent issues. The golden thread running through his exhilarating new book is the challenge of maintaining our collective and individual focus in the face of constant and disorienting change.
Are we still capable of understanding the world we have created?

‘Truly mind-expanding… Ultra-topical’ Guardian

21 Lessons is, simply put, a crucial book’ Adam Kay

About the Author

Yuval Noah Harari

Prof Yuval Noah Harari has a PhD in History from the University of Oxford and now lectures at the Hebrew University of Jerusalem, specialising in World History.

Praise for 21 Lessons for the 21st Century

“Truly mind-expanding… Ultra-topical… Harari’s big selling point [is] the ambition and breadth of his work, smashing together unexpected ideas into dazzling observations.”


“There is surely no one alive who is better at explaining our world than Yuval Noah Harari - he is the lecturer we all wish we’d had at university. Reading this book, I must have interrupted my partner a hundred times to pass on fascinating things I’d just read. Harari has done it again - 21 Lessons is, simply put, a crucial book.”

Adam Kay

“Erudite, illuminating, vivid. [Harari’s] lessons suggest new ways of thinking about current problems… a splendid, sobering, stirring call to arms.”

Sunday Times

“Fascinating… compelling… [Harari] has teed up a crucial global conversation about how to take on the problems of the 21st century.”

Bill Gates, New York Times

The Times

“Harari… is a rare voice of calm reassurance, slicing through the chaos and uncertainty of the modern age.”

Allan Hunter, Sunday Express

“Harari thrills his readers because he addresses the biggest possible topics with confidence and brio. Compared with the subjects he tackles, anything else we might read looks piffling and parochial.”

Evening Standard

“Harari’s genius at weaving together insights from different disciplines, ranging from ancient history to neuroscience to philosophy to artificial intelligence, has enabled him to respond to the clamour to understand where we have come from and where we might be heading… 21 Lessons is lit up by flashes of intellectual adventure and literary verve.”

Financial Times

“Modern life can seem overwhelming. Fortunately, Yuval Noah Harari's new book, 21 Lessons for the 21st Century, is on hand to guide us through it. Poolside reading with purpose.”


“[Harari’s] purpose is to reveal the hard-learned lessons we have all already encountered this century… the persuasiveness of Harari’s philosophical analysis, and the engaging quality of his writing, is hard to deny.”


“More comprehensible [than Sapiens and Homo Deus]... showing you things you thought you knew about in a completely new way… I find Harari’s writing exhilarating.”

Radio Times

“Written in the author’s trademark lucid prose, the book makes difficult concept comprehensible, and is very much a work for our times… 21 Lessons absorbs from start to finish.”

Ian Thomson, Tablet

“A terrific primer on where we are now and where we might be heading… Harari is a superb global cartographer, and 21 Lessons for the 21st Century is a lucid and essential read.”

Marina Vaizey, Arts Desk

“Bound to be one of the biggest books of the autumn... Exhilarating… compulsively readable and with almost every page providing something juicy to chew on.”

Reader's Digest

“Intelligent, lucid and refreshingly unpretentious.”


“The book contains many gems… compelling… accompany the author as he peers fascinatingly into the future.”


“Harari’s purpose is admirable. He wishes to empower ordinary people with his clear thinking.”

Liz Ryan, UK Press Syndication

“It feels urgent and necessary, as though it is capturing a crucial moment in time… It is a direct call to action and probably the most genuinely impactful of all three Harari books.”

Culture Calling

“Harari effortlessly jumps between diverse topics.”

Dov Greenbaum and Mark Gerstein, Science
