Lenat has come to the conclusion that his celebrated computer programs, AM and Eurisko, despite impressive achievements, ultimately f ail as creative discovery systems. The paper discusses Lenaťs various attempts to model sustainable creative intelligence, primarily within the paradigm of symbolic processing. Lenaťs current approach requires a larger knowledge base than that of his previous efforts, and in fact Lenat hopes that his new system, Cyc, will have achieved a human breadth and depth of knowledge in the relatively near future. It is concluded that the Cyc project should be extremely important f or future A.I. research, making a significant contribution to the connectionist/symbolist debate.
