“But the height of city buildings is a purely exterior one. Elevators do away with the heroism of stair climbing so that there is no longer any virtue in living up near the sky. Home has become mere horizontality. The different rooms that compose living quarters jammed into one floor all lack one of the fundamental principles for distinguishing and classifying the values of intimacy”
