The scientific facts, which were supposed to contradict the faith in the nineteenth century, are nearly all of them regarded as unscientific fictions in the twentieth century.
In fiction writing, I would say there are several different strands that have been woven through my own writing, and each influenced by a different group of writers.
Science fiction is never about the future, in the same way history is rarely about the past: they're both parable formats for examining or commenting on the present.
Truth is more of a stranger than fiction. When in doubt, tell the truth. If you tell the truth, you don't have to remember anything. Most writers regard the truth as their most valuable possession, and therefore are economical in its use.
