Tomorrow morning, at 9 am Sydney/Melbourne time, Radio National's "Life Matters" program will have an episode on disbelief based around 50 Voices of Disbelief: Why We Are Atheists. I'll be a guest on the program, as will some other contributors to the book (Jack Dann, Philip Kitcher, Emma Tom, Sean Williams). I gather that one theme is likely to be what can replace the role of religion (in providing community and a structured understanding of the world) for those who need it. There will be a talk-back component, and the show will go for an entire hour. Do tune in if you have time.
