Abstract
The theme running through these cooperative studies is the relation between automated fields of communication and control, and the various strata of human behavior. The question of the stratification of behavior is beginning to receive serious attention from the standpoints of ecology and cybernetics. One can only welcome the explorations of this imaginative group of authors in areas as promising as those of form, information, and life ; communication, information, and poetic language ; the role of information in the human sciences ; physics and information ; and knowledge and information. Once again E. Paci is the one who scans the largest territory.—A. M.
