The essence of hard science fiction is hope that given all we know, humanity will triumph in the end. Because the science we know is hopeful in that it presents no requirement for failure, we, certainly I, expect humans to outlast Earth. Reality is what actually happens, of course, but isn’t that what humans do, make things happen? In my fiction, the definition of intelligence is the ability to decide what ought to be and then make it so. To quote my own novel:
“The consequences of the Big Bang should have flowed like rows of falling dominoes; the physical universe should be predictable. But it ain’t, because intelligent life forms are messing with it.”
– Ambrose Phoenix, The Phoenix Diary
We all write our stories from some operational definition of our genre. The above is mine.
Let’s use the Comments section to add more definitions: How do you define your own genre in a way that helps you to write your stories?
