sorry but you’ve phrased her point in a way that makes my brain unable to parse or respond to it bc i’m a dumbass. but i think this is maybe the telling sentence:
if we leave aside any assumptions about what readers will do and focus on what’s implied about the works themselves, all she’s really saying, as far as i can tell, is that tolkien’s writing is pure fiction whereas pynchon’s at least contains elements of nonfiction. so if we assume that she’s trying to point out a weakness in tolkien’s work, then she’s getting close to a sentiment like this: why read some useless made up story when you could actually learn something about the real world.
don’t want to pin this too much on turner, who it looks like has written fiction herself… but the main reason that i find a few passages from that lrb article tiresome (passages that might seem innocuous to most people) is that i think they point toward a viewpoint that’s prevalent in a lot of highbrow circles and has had a really bad influence on art. a viewpoint that amounts to distrust or even fear of the imagination, of the human capacity to just make shit up.
i think a lot of people in or adjacent to academia find themselves in a predicament like this: they first came to love art/lit because of the sense of wonder they got from its immersive, escapist diegetic qualities, but then they went to college and internalized the belief that art is about saying something, commenting on the real world. it's not just that their values change, it's that the old value set becomes actively at odds with the new one. suddenly the qualities they so viscerally appreciated as children appear obfuscatory, cowardly.
so you get fiction writers who, on some level, have very mixed, confused feelings about the concept of fiction. the result is that serious art comes to mean concept art and auto-fiction. this stuff could only be venerated in a cultural environment that values insight far more than imagination. whereas i'm the opposite way. if i wanted insight i'd just read philosophy and i'd only turn to art if i wanted imagination. that's literally, definitionally, the distinguishing quality of fiction, so why act ashamed of it? i'd rate old akira toriyama stuff (let alone tolkien) way higher than some short story about a 27 year old in an mfa program in iowa.
tl;dr i’m a genius and all academics are (in the britsh sense) thick as fuck
