In his books on computers and cognition, Hubert Dreyfus claims that 'symbolic AI' is a degenerating research program. In this review John McCarthy, a Professor of Computer Science at Standford University defends symbolic AI. McCarthy focuses mainly on the logic-based approach, a part of the symbolic AI. Within logic-based AI, he emphasizes one development-formalized non-monotonic reasoning, because it illustrates intermittent but definite progress.
