I don't want to say "I told you so," but I was re-reading _The Bloody Chamber_ when I came upon those two words, "wild surmise," which had also appeared in _Under the Volcano_ (anybody remember where?), and I thought: well, they--meaning "you," my students--can say that I warned you that this phrase, and more particularly this idea, would show up in our reading. Please do yourselves and me a favor and think seriously about why this idea/phrase/condition keeps turning up in our reading. It will take you into some interesting cognitive corridors.
And if you want a pop culture parallel, think about those moments in Spielberg's films when someone (often a child) looks at something (usually looks up) and sees something that he/she doesn't understand but which causes his/her jaw to drop open; the word for this (recently corrupted and co-opted by the Bush Administration) is "awe."
