In 2007 Anthony Grayling wrote Against All Gods, a collection of polemical essays attacking religion. Now in To Set Prometheus Free he develops those themes more comprehensively, unpicking the claims and arguments of religious apologists, summarising the views of his fellow secularist (Bertrand Russell in particular detailing the controversy over \'Intelligent Design\' and outlining his personal, naturalistic world-view. He robustly calls for humanity to choose deliverance from religion because, as he puts it, \'large portions of mankind remain in some degree in thrall to myths dating from an ignorant and illiterate past.\'
