John C. Wright explains why in the midst of delving into literary aelvipology.
We are in the Dark Ages, and the darkness influences all things in society, including speculative literature. I mean the term not as an exaggeration or a metaphor: the technological products of our enlightened forefathers spring from the worldview which says science is a proper way to discover the mind of God by studying His works. Eliminating that God from one’s worldview eventually eliminates the respect for human life, free thought, and reason in law and custom which are necessary precursors to scientific endeavors, and eliminating science eliminates technology. Once the lamps go out, the darkness is everywhere, even in the little corners of society where children read books about spacerockets or elves.
The moderns have been taught to hate and loath their own country, their ancestors, their parents, and been told everything written before the current day is racist, sexist, homophobic, Islamophobic, transcismophobic, and pure evil. These nutbags think that their own standard bearers of the Progressive movement, the founders of their genre, were not Progressives like themselves.
One need only hear sexual libertarian and radical egalitarian nut Bob Heinlein being excoriated as a member of the misogynist phallocratic patriarchy to realize how far off the edge of the world the lunatics have sailed the ship of fools.
This is not some lunatic fringe belief. It is lunacy, of course, but not fringe. It is mainstream. The core institutions and standard bearers of Science Fiction, the largest publishers, the most prestigious awards, our once-respected guild the SFWA, the oldest and most famous magazine: they all buy into the narrative and all support the narrative with a singleminded fury that is Bolshevik in its vehemence, patience, and pettiness.
Progressives hate the past and seek forever to blacken, demean, and obliterate it. Anyone reading the older books would see immediately that the modern works are only merely equal, not as innovative, and that the modern award-winning works are notably inferior.
The notion of progress is the notion that the past is bad and the present is better and the future will be better yet. If you read old books and find that they are either slightly better or remarkably better than modern offerings, you see a decline, not a progress, and the foundation of progressivism, is overthrown.
The reader will probably recognize that while the elves of Selenoth are a blend of Tolkienian and Longaevian, the Faeries of the Eternal Warriors trilogy are explicitly Longaevian.
