Bernard-Henri Lévy, Edith Hall and Simon Critchley

From people-watching with Aristotle in a London park, to meeting in a luxury hotel at midnight to discuss the fate of a continent, to using a lunchtime five-a-side game as the starting point for a meditation on the human condition, this programme treats 'philosophy' as a verb rather than a noun. Bernard-Henri Lévy is in London to perform a one-man play on Brexit. Simon Critchley's new book is What We Think About When We Think About Football, and Edith Hall's is Aristotle's Way: How Ancient Wisdom Can Change Your Life. Shahidha Bari talks to each of them about bringing philosophy out of the academy. Producer: Luke Mulhall
