The death of the author as a movement in cultural production had a performative bite – given that it was concerned with authority, simply to doubt from a position of economic or authorial power undid some of the power of the author. It’s an anarchist position in literary studies.
Scripturience is always eschatological in the end.
I read in Luke Kennard’s poem Ghost Story, where he talks about god making the soul pass through all possible human lives as a kind of edification or explanation or challenge or trick or joke, and remembered a very similar thought I’d had since childhood – except I imagined it would be every animal I ever stepped on, every living being including the long and interminable lives of trees, the short and inexplicable lives of mushrooms. I just remembered an ancestor to this idea in my head, or maybe the source of it, in Douglas Adam’s book where there exists a creature that in all of its incarnations is killed by Arthur Dent. Incarnations shares its root with french carné, and carnivore. Lives are the mind made meat, expendable and eaten by god’s great experiment.
I can imagine a Koan based around a similar idea – if you are to live the life of every person you have ever met, every plant you have ever seen, and every animal, fish and vegetable that you have ever eaten, would you agree to live? And then we can go on to include rocks and stars and clouds in this, and the answer might be – but this is how things already are. You are living the last life in the universe.
Art for art’s sake is just a warning not to expect more.
