The 1st October 2009 saw the launch of The Atheist Guide to Christmas. This episode of Little Atoms features Neil and Padraig in conversation with 3 old friends of the show, editor Ariane Sherine, and contributors Natalie Haynes and Josie Long. We discuss the genesis (!) of the book, our contributions, the ideal christmas, and argue over the definitions of atheism, agnosticism and secularism, then the rubbishness of various ex-boyfriends gift buying skills are discussed.
