I often use the metaphor of Perseus and the head of Medusa when I speak of science fiction. Instead of looking into the face of truth, you look over your shoulder into the bronze surface of a reflecting shield. Then you reach back with your sword and cut off the head of Medusa. Science fiction pretends to look into the future but it’s really looking at a reflection of what is already in front of us.

Draw a line. Write a line. There.
Stay in line, hold the line, a glance
between the lines is fine but don't
turn corners, cross, cut in, go over
or out, between two points of no
return's a line of flight, between
two points of view's a line of vision.
But a line of thought is rarely
straight, an open line's no party
line, however fine your point.
A line of fire communicates, but drop
your weapons and drop your line,
consider the shortest distance from x
to y, let x be me, let y be you.
