Sanderson explains to the guests in Worlds Apart that "Our idea
of space as a vast empty container, like the inside of a packing case,
is really quite artificial. . . . it was simply the first impression
which a newly-awakened, brain-focused thinking had of its situation in
the universe. For the first time it realized itself as a centre in the
fullest possible sense of the word. That is why the study of perspective
only began at about the same time as the scientific revolution . . . "
