I was reading through various list serve posts tonight, and came across a thread on the WPA list noting that Joseph Williams has died. Wow. He's the author of several books and what I consider to be the cleverest article in composition/rhetoric: "The Phenomenology of Error."
Without Williams' piece on error, I'd have no way to model for students how invention can function at the level of form in an essay. With his piece, I'm always able to demonstrate how typical essay writing is rhetorically arrested by keeping form free of invention. It's an article that demonstrates just how powerful play can be in academic argumentation.
What a clever, clever man. And what a loss.
