Currently in Bill Gates;s bookbag and FT Books of 2018Increasingly, the demands of identity direct the world;s politics. Nation, religion, sect, race, ethnicity, gender: these categories have overtaken broader, inclusive ideas of who we are. We have built walls rather than bridges. The result: increasing in anti-immigrant sentiment, rioting on college campuses, and the return of open white supremacy to our politics. In 2014, Francis Fukuyama wrote that American and global institutions were in a state of decay, as the state was captured by powerful interest groups. Two years later, his predictions were borne out by the rise to power of a series of political outsiders whose economic nationalism and authoritarian tendencies threatens to destabilise the entire international order. These populist nationalists seek direct charismatic connection to ;the people;, who are usually defined in narrow identity terms that offer an irresistible call to an in-group and exclude large parts of the population as a whole.Identity is an urgent and necessary book: a sharp warning that unless we forge a universal understanding of human dignity, we will doom ourselves to continual conflict.
