Scale allows us to give a meaning to the value of urban measure and to grasp the degree of it beyond which it is necessary to update the paradigms by which its new formal extent is understood. If it is that which is placed between man and the world that establishes an agreement between thought and space, then changes in urban magnitude imply a redefinition of the relationship between the measures of man, of his liveable environment and of the total urban context. The changes of scale which lead from the space ‘of contact’ with urban places to expanded spaces, experienceable by means of artificial infrastructures, outline the narration of an ‘urban biography’ composed of the succession of construction dates and types of style. What appears is the knowledge that pierces every historical transformation: the substantive knowledge which identifies a city as a place where the self-education of society is practised.
