From the correspondence with Orwell he seems to just have wanted to be the one who predicted the dystopian future most accurately. I looked into him a little bit but I'm not obsessed, I did read BNW IIRC It is a warning in some sense, it's been a long time but the main character decries his society and chooses to live with the 'savages' IIRC? I haven't read The Island or Doors of Perception though. Also yeah he literally thought LSD should be the play thing of the wealthy elite and over socialized academics because of his personal desire to continue using it, it's an incredibly pretentious double standard. I just thought it was an interesting parallel and BNW was like one of like 3 books I actually enjoyed being assigned.
