Immediately upon publication, this book "stirred up quite a scandal, and introduced the world to a new athlete, all the harder to beat, since he hit you from all sides at once; he seems to assume different forms, and in this respect he could say, like the devil, 'Our name is Legion'" (Naigeon, 'Memoires'). A scandal, to be sure: the book was promptly banned, burned and its anonymous author was pursued by the authorities.The author later became a guiding mind of the Englightment with his Encyclopedia. In this, his first published book, Diderot launches a sustained attack on his twin enemies: superstition (i.e. Christianity, the Bible, miracles, and revelation) and atheism. The truth, he thought, lies with deism: God is knowable through his masterpiece, the world and all it contains.
