This material was shipped to Fenwick Library Special Collections, George Mason University, Fairfax, VA on 23 October 2000. This was one of the earliest presentations of the `Domain of Science' graphical design, in a talk given at the American Society for Cybernetics meeting, where the author displayed a transparency of his earlier DOS figure titled " A Model for a Domain of Science", and proposed the use of a Domain of Science model as a means of judging the merit and validity of laws, stating that `laws are legitimized by their relevance in applications'. In Warfield's later papers this figure was elaborated reworded to become the more familiar Domain of Science graphic on the cover of his book, but the concept behind the early figure and the more recent graphic is exactly the same. The paper was never a computer document. Warfield wrote it with an IBM typewriter. Rose Warfield scanned the typewritten version to a PDF file.
