What do we know about the Book of Job? Not very much. The hero complains endlessly. He has just lost his children all his livestock. He scratches his ulcers. The misfortunes of which he complains are all duly enumerated in the prologue. They are misfortunes brought on him by Satan with God's permission.We think we know, but are we sure? Not once in the Dialogues does Job mention either Satan or anything about his misdeeds. Could it be that they are too much on his mind for him to mention them?Possibly, yet Job mentions everything else, and does much more than mention. He dwells heavily on the cause of his misfortune, which is none of those mentioned in the prologue. The cause is not divine, satanic nor physical, but merely human.
