Another attempt on my part to participate in the mundane-language theme. I could not decide if I wanted "Literature is difficult" in focus or "which challenges intellect" and I opted for the latter.
Seeing the discussion about this theme and the back and forth on whether or not language is a mundane "object," I thought perhaps I could point out that some words are objects--direct objects in particular (intellect in this case). Leave it to the English teacher to get all nerdy on this one.
Oh, and nothing more boring or mundane than diagramming sentences or diagramming language! I slay myself. Yes, I'm taking a break from grading and it shows.
