RaveThe Times (UK)\"There is a new and frantic urgency in Harari’s writing, a tone that is quite different from the agreeable, leisured, scholarly tone of Sapiens, or from the cool speculative evaluation of humankind’s long-term future in Homo Deus, the book that followed it. We are running out of time, he says, to deal with the biggest challenge our species has ever confronted ... Harari’s book ranges across a huge territory: the nature of justice, the seductive appeal of identity politics, the failures of liberal democracies. It is erudite, illuminating, vivid. His lessons suggest new ways of thinking about current problems; they are less about answers than pleading with us to recognise and respond to the immediate threats they pose ... a splendid, sobering, stirring call to arms.\
