"Programs with Common Sense was probably the first paper on logical AI, i.e. AI in which logic is the method of representing information in computer memory and not just the subject matter of the program. The paper was given in the Teddington Conference on the Mechanization of Thought Processes in December 1958 and printed in the proceedings of that conference. It may also be the first paper to propose common sense reasoning ability as the key to AI" (http://jmc.stanford.edu/articles/mcc59.html).
