In his poem "Let Us Consider" Russell Edson is talking about us, our human potential for nuttiness and identification (in the korzybskian sense of the term) not just about some 'strange' wackos. You can read in Korzybski's book Science and Sanity about the continuum that he saw from objectification of higher order abstractions, to delusions, to illusions, to hallucinations. You can also read about the fuzzy continuum from 'sane' (and who is fully sane) to unsanity to insanity. I know many so-called 'normal', so-called 'sane' people who are clearly going in the 'wrong' direction along that continuum and are not as far as they think from frying roses and scraping shadows. Some of them have thought of themselves as 'general semanticists'. I, of course, am not excluded from consideration. "Let Us Consider", indeed.
