This interview explores the key themes and ideas in Daniel Chernilo's recent book Debating Humanity: Towards a Philosophical Sociology (2017). It is a hugely ambitious book that tackles a range of questions around the notion of humanity and the category of the human. Drawing on a wide range of thinkers, the book pushes at a number of far-reaching issues, problems and questions concerning humanity. It's a rich text that develops themes that are likely to be of interest across the social sciences and humanities, not least because it tackles some of the most difficult and crucial questions that face social theory today. The interview was conducted in October 2017.
