Here is a fairly long video of a discussion between myself, Richard Swinburne (philosopher), Peter Atkins (chemist), Ard Louis (physicist), and also Richard Dawkins (who was in the audience) at one point. The theme was Life, The Universe and Everything – The Quest for Truth.
My main contribution is at 39 mins 30sec.
(nb. Dawkins is at 1hr 18 min 20 sec [he has a pop at Swinburne and me] and my response to Dawkins at 1hr 24 min 30 sec).I posted on this before, shortly after the recording. Go here.
This included quite a good discussion on the nature and value of philosophy, I thought.
