The two Johns behind QI, Sandi Toksvig, Jon Ronson and philosopher Simon Blackburn on being good

John Lloyd and John Mitchinson are the minds behind the TV show QI, and in this episode introduce their Book of General Ignorance. 

The original chair of QI was Stephen Fry and he was replaced by Sandi Toksvig. Here she introduces her story Melted into Air.

Journalist Jon Ronson explains how he researched his amazing book 'Them - Adventures with Extremists' and philosopher Simon Blackburn explores the notion of being good.  The interview was recorded 20 years ago but the quandaries remain just the same.
