The AARON program has been generating original artworks for almost 30 years, but is denied by its own author to be creative. The author characterizes creativity as a directed movement towards an illdefined but strongly felt end-state for the individual's work as a whole, not as a characteristic of any single work and profoundly knowledge-based in the sense of externalizing the individual's internal worldmodel and system of belief. He suggests that a creative program would be one that was able to modify the belief-based criteria that inform the rule-base in which expert knowledge is represented, not one that is able simply to modify the rule-base itself.
