Not that this has much relevance to the thread, but I used the term, the literary genre, because I see it being used as such. Let me hint at why this is.
Sometimes we have to accept that things are defined by what they are not as much as what they are. So, if an author (or agent or publisher or critic) says that a work of speculative fiction specifically
isn't a duck SFF (even though it's
waddling about, quacking happily plainly fantasy or SF) but is,
instead, a literary work, I think I see that what is happening is the partitioning of a shared, two-dimensional space,
not the
additional elevation of a work based on those certain qualities. Such elevation would leave the work as being, say, "a work of Fantasy that easily shows its literary mettle." So if said author, agent, publisher and critics said, "Of course it's SFF, but its qualities mark it out as a literary gem," the Wiki definition might be seen to be working in practice rather than just in theory.
And let's face it, the clue is in that Wiki quote:
held qualities to readers outside genre fiction
which seems to assume that the world must inevitably divided into genre fiction (of various types) and something else, the latter of which is the preserve of a self-defined elite**that,
by definition, does not contain those with a wider (though not necessarily shallower) experience of reading fiction***.
Anyway, here's a question: when a piece of fiction has taken on the guise of a literary work, is indeed presented as such by its creator, but signally fails "
to engage with one or more truths or questions, hence relevant to a broad scope of humanity as a form of expression", what is it? Is there a genre for these aspiring literary works that don't make the grade? In the criticism of such a work, is it ever stated that, "though attempting to be literary, and eschewing any of the tropes of <pick a genre>, it remains a work of..." Well, what, exactly? "Literary fiction", perhaps...?
** - Elitism by self-definition/election is not the same as elitism won by the attainment of admired qualities.
*** - Fiction because, let's face it, SFF isn't the genre that
most people would select if they were engaged in writing an autobiography.
