I came across this in my sophomore English class at Buena High School, taught by Mrs. Gloria Roka. She picked it up at something called “A Workshop on Ignorance” (I always thought that whoever named that had a sense of humor). The professor who wrote this was C.A. Kerwin, who I believe teaches at the University of Arizona.
