A bunch of transparencies that were never used because paper (although eventually published in Polish) was never presented at a conference. The paper was not published in English, but was published under the title "Proste Modele Systemowe Oparte Na Skomplikowanych Zalozeniach: Klucz do Spojnosci w Zlozonym Uniwersum".(Simple System Models Based on Sophisticated Assumptions)1989 Prepared for the 1988 Annual meeting of the American Association for Advancement of Science (AAAS), the paper was to be presented at 2:30 p.m. 12 Feb. at Hynes Convention Center, Boston, as part of the SCIENCE AS A SYSTEM symposium chaired by Russell Ackoff. The paper was never presented, due to a bad snowstorm in Boston on 12 February. Warfield never got to that conference; his flight from La Guardia to Boston circled quite a while, never landed, returned him to New York, and he came back home. Later, Warfield sent the paper to Gasparski, editor of the Polish journal. The article was translated into Polish, and was published in the journal Zagadnienia Naukoznawstwa (Science of Science), published in Warsaw, Polish Academny of Sciences, No. 3-4, 1989, pp. 653-662.
