"Hard" science fiction probes alternative possible futures by means of reasoned extrapolations in much the same way that good historical fiction reconstructs the probable past. Even far-out fantasy can present a significant test of human values exposed to a new environment. Deriving its most cogent ideas from the tension between permanence and change, science fiction combines the diversions of novelty with its pertinent kind of realism.

I don't know where the characters are going to go or what's going to happen. I know that something inevitable will happen. I know that they want certain things and they're in a certain room and they smell like this and they look like that. More often than not, an entropy creeps in that strangles me, and then the inevitable happens. I don't know if I have the ability to write an ending like My Fair Lady's, when everyone gets what they want after a few minor conflicts. If I tried to write that it would just be false. Or I'd have someone enter with a machine gun.
