This vital study offers a new interpretation of Humes famous Of Miracles, which notoriously argues against the possibility of miracles. By situating Humes popular argument in the context of the 18th century debate on miracles, Earman shows Humes argument to be largely unoriginal and chiefly without merit where it is original. Yet Earman constructively conceives how progress can be made on the issues that Humes essay so provocatively posed about the ability of eyewitness testimony to establish the credibility of marvelous and miraculous events.
