There is some irony to the fact that my blog entry on April Fool's Day did not discuss the theory of humor, much less fools. It is especially ironic, because in the paper that I submitted for the book chapter, I have a section discussing the theory of fools and Ignatius as a fool. So happy foolish May Day, preceded by an April Serious Day.
However, in saying that this situation is ironic, I do not mean the type of irony investigated in Linda Hutcheon's book, Irony's Edge.
