Atheism in a Post-Religious World - Book Review Tremblay labels religion a swindle and mental terrorism and explains, convincingly, why he chose these epithets. He demonstrates the inextricable link between the belief in the afterlife and immorality and castigates religion's intolerance coupled with its ever-shifting philosophical goalposts. Its dogmatism leads to a loss of experiential richness and to negative cognitive consequences to both the believer and his milieu. philosophy • mind • ethics • robot • turing
