In this first podcast, presented by Bristol Festival of Ideas and sponsored by the Philosopher's Magazine, George Miller looks back at some of the highlights of the 2008 Bristol Festival of Ideas.

Baroness Susan Greenfield, Professor of Pharmacology at Oxford University, Director of the Royal Institution and a member of the House of Lords, talks about her new book 'ID: The Quest for Meaning in the 21st Century'.

Raymond Tallis, polymath, poet and Emeritus Professor of Gerontology, then discusses what goes on inside our heads with reference to his new book, 'The Kingdom of Infinite Space'.

He is followed by Alan Sokal, Professor of Physics at New York University, who talks about pseudo-science, religion and misinformation in public life.

This podcast is 30 minutes long (28MB), and is the first in a series that will be issued each month from now until autumn. If you would like to hear more interviews with selected speakers from this year's Festival, please visit our website at: www.ideasfestival.co.uk/audio.html.
