Stanford technical report number 26 by George E. Forsythe, 1965.

I consider computer science to be the art and science of exploiting automatic digital computers, and of creating the technology necessary to understand their use. It deals with such related problems as the design of better machines using known components, the design and implementation of adequate software systems for communication between man and machine, and the design and analysis of methods of representing information by abstract symbols and of processes for manipulating these symbols. Computer science must also concern itself with such theoretical subjects supporting this technology as information theory, the logic of the finitely constructable, numerical mathematical analysis, and the psychology of problem solving. Naturally, these theoretical subjects are shared by computer science with such disciplines as philosophy, mathematics, and psychology.
