Supposed by whom?

Oh, Roy Harris comes to mind, but mainly because I was just reading an article of his in Linguistic Thought in England: 1914–1945. He mentions it in connection with the British philosopher G. E. Moore, but it's really just a fancy name for what happens during communication. I didn't say I believed it. I think communication is, at best, an epiphenomenon of parole. That's on my good days.
