as human knowledges.

     The “simultaneous field” of electric information 
structures, today reconstitutes the conditions and need for 
dialogue and participation, rather than specialism and private 
initiative in all levels of social experience. Our present 
involvement in these new kinds of interdependence produces in 
many an involuntary alienation from our Renaissance heritage. 
But for the readers of this book it is hoped that we can deepen 
our understanding both of the typographic and the electronic 
revolutions.
