So I've been reading Kenny's book on Wittgenstein. He said he wrote it because he was concerned that important lessons Wittgenstein had to teach were being forgotten (as of the early 70s). Of course, Wittgenstein's star has, if anything, sunk further since then. I was not impressed with the lessons Kenny derived from Wittgenstein; I still think his reputation has declined for good reasons. But it gave me an occasion to ponder what those reasons are, and I have a theory.
