Abstract
Inspired by the idealism embodied in Russell and Whitehead's "Principia Mathematica," Wiener marched along a different and unique path toward sciences of intelligence and behavior which culminated at "Cybernetics: Or Control and Communication in the Animal and the Machine" 70 years ago. Since then, we have witnessed the birth of Cognitive Science, Artificial Intelligence (AI), Computational Intelligence, and many other new research fields and disciplines, all of which have been catalyzed by Cybernetics. The IEEE Systems, Man, AND Cybernetics Society and this Transactions on Cybernetics have become the focal point of the broad cybernetics community by promoting the theory, practice, and interdisciplinary aspects of systems science and engineering, human-machine systems, and cybernetics principles. It is a time of celebration and reflection.
