In this wonderfully clarifying essay, Waleed Aly examines what happened to liberalism. As a set of ideas, it offered formal equality and guaranteed freedoms. Yet more and more, we live in a post-liberal world of warring identities.

Aly looks and how and why this has happened. He analyses thorny questions of free speech and equality of opportunity. And he examines the limits of liberalism, the rise of illiberal democracy and the new battles over truth and justice.
