This is a much needed book. It helps to build a bridge between The Two Cultures whose separation plagues C.P. Snow and many others. The very word “cybernetics” is a useful clue to the central meaning of the electronic revolution. The speed-up of information movement creates an environment of “information overload” that demands pattern recognition for human survival. It was natural therefore, for the first explorers of this field to use a term from navigation. In economics it has become natural to speak of the decision-making of tomorrow as taking place in a world economy. Instant access to and retrieval of information creates entirely new economic and political situations. The new information environment created by the new electronic technologies is quite imperceptible and can only be discovered by special inventories of changing trends and changing human responses to the new environment.
