I am a big fan of good, literary science fiction. Of course I am thinking of the work of such writers as Harlan Ellison, Ray Bradbury, H.P. Lovecraft, among others. if you reach back to such writers as Jules Verne and H.G. Wells, you will begin to see that good fiction with those keys scientific elements can truly bring out a study and/or critique of humanity and its advancement. Other genres can study the human condition, but not like this.
Of course I have read cross sections of the entire history of the genre, from Verne and Wells, throughout the pulp and early digest magazines, through the "New Wave" Movement spurred by Ellison's Dangerous Visions anthology of tremendously awesome, never-before-published stories, to the work of such great authors today as L. E. Modessitte, jr. I am sure you have of isaac Asimov and Robert Jordan, but have you read any of John Jakes' early writing? this historical novelist started writing science fiction, and it was tremendous stuff, even if it wasn't as groundbreaking as his North & South trilogy.
In my reading, I have come across several authors whine about how they are not taken seriously by mainstream critics, who call them "hacks" and "near-illiterates". this pains me, because to me some of the greatest novels and stories fall under the speculative fiction category (I lump alternate history and fantasy in with this, as well as horror and dystopian literature, because they get lumped together with the negative comments anyway). Have you read "Flowers for Algernon" by Daniel Keyes? Did it make you want to cry? Can you remember anything else this man has written? I believe I have made my point. If not, look to The Hobbit. If you have a problem with that example, then apparently we will not get anywhere in our argument, because we will have no common ground to begin with.
Why is this so? May I draw your attention to the film industry? What with some of the most dreadful schlep put on the screen to try and bring the emotional impact of our beloved words, how can we not want to be blinded so as to not witness it again? I must admit that some of Star Trek was watchable (Harlan Ellison, who is among my favorite authors, wrote one of the show's most memorable episodes, so I have to give reference to the good points about it), but on the whole it was glorified explosions and sex and violence. And not that good science fiction doesn't have any of that, but there's more to the literature than just getting her into bed. There's that address to humanity, getting her to realize where she has steered off-course, and making changes. We are losing that in the film industry.
Take a look at Alien, Independence Day, and the later Roger Corman productions. Note how that no philosophy is discuss in any way besides the superficial. I believe I have made my point. The days of Fahrenheit 451 are over, or maybe what the book predicted was true, and we end up losing something special along the way.
It makes me sad to see it happen. I try to get it to stop, but I am one voice. Those of you who agree with me, we must stand up and fight this, so we do not lose the words that have moved us so many times. Join me, and let's keep the words that God has graced us with through the minds of his writers. Join me, and let's keep good science fiction alive.
