In the last decade, atheism has leapt from obscurity to the front pages: producing best-selling books, making movies, and plastering adverts on the side of buses. There’s an energy and a confidence to contemporary atheism: many people now assume that a godless scepticism is the default position, indeed the only position for anybody wishing to appear educated, contemporary, and urbane. Atheism is hip, religion is boring. Yet when one pokes at popular atheism, many of the arguments used to prop it up quickly unravel. The Atheist Who Didn’t Exist is designed to expose some of the loose threads on the cardigan of atheism, tug a little, and see what happens. Blending humour with serious thought, Andy Bannister helps the reader question everything, assume nothing and, above all, recognise lazy scepticism and bad arguments. Be an atheist by all means: but do be a thought-through one.
