"Ricochet vision"

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. So you have a ricochet vision, a ricochet that enables you to have fun with it, instead of being self-conscious and superintellectual.

Ray Bradbury, interviewed by The Paris Review

I wonder if Bradbury’s metaphor may be useful in thinking about all art — art is a reflecting shield that allows us to safely glimpse an image of the future.
