In Richard Powers’s novel The Echo Maker, a young man suffers a brain injury in an auto accident and is afflicted with Capgras syndrome. When he wakes from a coma, he can see and even recognize family members and friends, but he takes them for impostors.
Samuel, the Billy Graham of his day, was adviser to the political leader Saul, the Pete Rose of ancient Israel. Samuel anointed Saul to be the first king of Israel. But soon (to quote James Thurber), “confusion got its foot in the door” and went through the entire “system.” Samuel observed Saul disobeying the explicit word of God, and it became Samuel’s job to inform Saul that God had rejected him as king.
