“[T]he reality of the public realm relies on the simultaneous presence of innumerable perspectives and aspects in which the common world presents itself and for which no common measurement or denominator can ever be devised. For though the common world is the common meeting ground of all, those who are present have different locations in it, and the location of one can no more coincide with the location of another than the location of two objects. Being seen and being heard by others derive their significance from the fact that everybody sees and hears from a different position.
[the] destruction of the common world [is] usually preceded by the destruction of the many aspects in which it presents itself to human plurality. … Men have become entirely private, that is, they have been deprived of hearing and seeing others, of being seen and been heard by them. They are all imprisoned in the subjectivity of their own singular experience, which does not cease to be singular if the same experience is multiplied in innumerable times. The end of the common world has come when it is seen only under one aspect and is permitted to present itself in only one perspective”.
H. Arendt, The Human Condition, p. 58.
