... The literature does not include any general discussion of the outstanding problems of this field. In this article, an attempt will be made to separate out, analyze, and find the relations between some of these problems. Analysis will be supported with enough examples from the literature to serve the introductory function of a review article, but there remains much relevant work not described here.Proc. Institute of Radio Engineers 49, p. 8-30

Particular attention is given to processes involving pattern recognition, learning, planning ahead, and the use of analogies or?models!. Also considered is the question of designing "administrative" procedures to manage the use of these other devices. The paper begins with a discussion of what is meant by "Intelligence" and concludes with a sec-- tion concerned with some techniques through which a machine might further improve itself by adding to Its collection of problem--solving methods. I. INTELLIGENCE I feel that it would not be useful to lay down any absolute defini-- tion of "intelligence" or of "intelligent behaviour". For our goals in trying to design "thinking machines" are constantly changing in relation to our ever--increasing resources in this area. Certainly there are many kinds of performances which if exhibited by a man we would all agree, today, require or manifest intelligence. But would we agree tomorrow?
