in perspective, parallel lines appear
to converge, distant objects appear to
be smaller, closer objects are more distinct.
in linear perspective, things disappear.
they don't really disappear, parallel
lines don't really converge. they stay apart,
forever at a distance and never
do touch. they stare forever at each other,
clearly and distinctly, no matter how far
from the eye they get. an observer
gets it all wrong, lacks perspective.
using perspective, we try to understand
and get it wrong anyway. things seem
to converge and disappear. they go on.
