Parabolas of Science Fiction

As a geometric term, parabola suggests a narrative trajectory or story arc. In science fiction, parabolas take us from the known to the unknown. More concrete than themes, more complex than motifs, parabolas are combinations of meaningful setting, character, and action that lend themselves to endless redefinition and jazzlike improvisation. The fourteen original essays in this collection explore how the field of science fiction has developed as a complex of repetitions, influences, arguments, and broad conversations.
