"Time sheds its qualitative, variable, flowing nature. It freezes into an exactly delineated, quantifiable continuum filled with quantifiable things . . . in short it becomes space".
This concept of time-space fits well into the space of the threshold as stage which appears to be a frozen space, between the temporal based home and street.
The relationship between the objects in this Euclidean threshold space are of a quantifiable continuum with the chair as a quantifiable thing.
