Psychologist Cass Seltzer's book, The Variety of Religious Illusion, has become a surprise runaway bestseller. Dubbed 'the atheist with a soul', Cass's sudden celebrity has upended his life and brought back the ghosts of his past. Over the course of one week, Cass's theories about our need to keep faith are borne out in ways he could never have imagined. 36 Arguments for the Existence of God is a stunningly original novel, which explores the varieties of the human religious experience in a story of obsession, consuming love, and divine genius. By turns hilarious, moving and devilishly clever, Goldstein's novel is an exhilarating romance of heart and mind.
