Cybernetics has fallen prey to snobs and journalists, who, in dealing with it, tend to mix myth with science. In this study we shall try to sift out the chaff, which a regrettable sensationalism has needlessly mixed with the good grain. Concentrating our attention on the rational bases and some of the lines of force of this new field of study, we shall try to eliminate the element of fable, but we shall not prohibit ourselves from opening windows on any perspectives that seem reasonable.
The notion of “information,” cornerstone of cybernetics, sheds light on the theory of knowledge. What is science, indeed, but an interpretation, which tries to be objective, of the flood of signals with which the universe submerges us? A Protean notion, it permits us to discover a certain unity among the most disparate phenomena. But it is a dangerous notion, too, because of the multiplicity of senses one may give to it.
