  A child has belief \(B\) that Hell is a real place located in the center of the earth. You disagree. This is a case in which you disagree with someone who you recognize to be your epistemic inferior on the question of whether \(B\) is true. You believe that Babe Ruth was the greatest baseball player ever. Then you find out that a sportswriter who has written several books on the history of baseball disagrees, saying that so-and-so was the greatest ever. In this case, you realize that you’re disagreeing with an epistemic superior on the matter, since you know that you’re just an amateur when it comes to baseball. In a third case, you disagree with your sister regarding the name of the town your family visited on vacation when you were children. You know from long experience that your memory is about as reliable as hers on matters like this one; this is a disagreement with a recognized epistemic peer.
