This great and exceptional writer formulated the above demand as early as 1962 – not in 2020.
However, both for 1962 and in general, there is an immediate justification for this statement: a certain distance is always needed in order to perceive something, including oneself, to observe and to at least potentially comprehend something because only from a distance are we able to understand and experience the other as different (from ourselves).
Wonderful as proximity can be, it equally harbours the danger of devouring each other and, thus, of dissolving both parties. A certain distance is, therefore, also substantial in proximity.
This is similarly true for the relationship of subjects to objects. The latter can only be seen as things, as something that is opposed to humans.
