Philip Dodd examines whatever happened to the concept of kindness with psychoanalyst Adam Phillips and historian Barbara Taylor, who argue in a new book that it is essential to our emotional and mental health. Plus a discussion of the influence of French writer Pierre-Joseph Proudhon, seen by many as the first ever anarchist thinker, and a review of the Darren Aronofsky film The Wrestler, which stars Mickey Rourke as a retired fighter, and which won the top prize at the 2008 Venice Film Festival.
