In this episode of UpFront, we challenge author and Harvard professor Steven Pinker on his new book, Enlightenment Now: The Case for Reason, Science, Humanism and Progress, in which he argues that data shows the world is becoming a better place. And in the Arena, we ask journalist Afua Hirsch and Claire Fox, author and director of the UK-based think-tank the Academy of Ideas, about racism in the United Kingdom, and the kind of conversations needed to address it.
