Ficiton comes from the space in-between the comprehensible and the incomprehensible.
The incomprehensible has many names: infinity, freeplay, Providence, the unexplained. As the lines are drawn bounding what we know as “reality”, as they are manipulated, drawn back or pushed forward, the incomprehensible remains. To be in a state of incomprehension: this is what is essentially human. No system can circumscribe desire, emotion, the unknown: though systems have been developed to limit our susceptibility, or sensitivity, to each (those of the devout, the solidier, the scientist, the capitalist).
Circumscribe: to calm, to negate, to repair, to grasp, to contain.
