Inexperienced scholars often imagine themselves writing for people more intelligent and knowledgeable than themselves. In other words, they are trying to break into the field or impress their professors. When I read my own sentences I am usually asking another kind of question: will a stupid person understand them?
What I mean is the following: I have trouble understanding the prose of Charles Altieri. Given that I am not excessively stupid, I see that as Altieri's fault, not mine. (Suppose I were average intelligence for an academic: Altieri would be eliminating at least 50% of his audience, by that measure.) I want to get to where the least experienced beginning graduate student could see what i am saying very easily.
I don't see this as condescending because I see myself as someone who doesn't grasp other writers' meaning all that quickly. I am willing to put the time in to understand Lezama Lima, but not Charles Altieri. In other words, there are enough difficult primary texts in m field, so I don't want to spend energy deciphering secondary texts.
