We are developing a model for human cognitive processing which assumes that a major component of the rules for calculating behavior are resident outside the individual, in the inherited, collective phenomena that anthropologists call 'culture'. Our model contains rules of behavior encoded in propositional structures such as frames or scripts, plus a method for calculating behavior by analogy. Propositional rules are transformed into situation state descriptions that are related by transformation operators which are also valid for transforming situations by analogy, and for planning by analogy. This kind of operator has been named "Appositional Transformation Operator' or ATO (1,2,3,4). To explore the ATO concept, we have constructed a computer simulation model of an artificial society, culture & universe-- a world derived from Edwin Abott's 19th-century fantasy, FLATLAND: A Romance of Many Dimensions (1884). The model is written in '[[I]1' (pronounced BAR BAR, for short), a UCSD-Pascal, TERAK based simulation language which allows for dynamic manipulation of the simulation rules. The form of the surface structure is essentially Pascallike; the shallow deep structure is essentially MESSY-like (5,6,7,8,9). The deep deep structure is based roughly on the Von Neumann universe (10). We use. the simulation model as a generator of operas, complete with textual, pictorial and musical output, all derived from a common semantic source. The output is in the medium of a videotape recording, and is generally entitled, REVOLT IN FLATLAND (3). We are currently working on generation of analogically derived variants, including metaphorical and surrealistic versions, through the use of ATO's as a calculting mechanism (4). We are also working on the incorporation of dramatic values in the basic versions of the opera.
