What do we really need to know in today’s world? In twenty-one bite-sized lessons, Yuval Noah Harari explores what it means to be human in an age of bewilderment

Sapiens showed us where we came from. Homo Deus looked to the future. 21 Lessons for the 21st Century explores the present.
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?

The great thinker of our age.

The 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

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

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

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.

John Thornhill, Financial Times

Intelligent, lucid and refreshingly unpretentious.


Harari’s latest epic study covers Brexit, fake news and welfare in terms so lucid your own IQ immediately leaps.

Evening Standard

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.


I’m predicting that 21 Lessons for the 21st Century will complete a Harari hat-trick of classics… The clarity of Harari's vision is astonishing... thanks to him, the world makes better sense to many more of us.

Bookseller *Book of the Month*

[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.


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

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

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

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

Compelling reading.

Daniel Snowman, Jewish Chronicle

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

Allan Hunter, Sunday Express

This is an important book.


21 Lessons is another extremely readable volume [from Harari].

Emily Nicolle, City AM

With Harari's incise vision and measured prose this is a book to convert those dormant anxieties and Evening-News-induced insomnia into a deeper, more empowered comprehension.

Culture Whisper

Harari effortlessly jumps between diverse topics.

Dov Greenbaum and Mark Gerstein, Science

A thought-provoking, provocative, informative, terrifying, fact-filled series of essays which get the reader thinking, worrying and hoping.
