This is one of the most elegant pieces of media theory I've read in a long time. The throughline from Plato's alphabet-shaped metaphysics to Spare's deliberate dismantling of the same system is quietly devastating, and the framing of technology as irreducibly tricksterish feels exactly right…
It also lands close to what I write about at Maze to Metanoia. So much of what makes anomalous experience so difficult to process culturally is that our inherited frameworks, shaped by exactly the literate rationalism you trace here, have no room for it. The buffered, abstracted self that the alphabet helped create is precisely the self that finds contact experience so destabilizing. Spare's turn downward rather than upward, toward embodied and atavistic knowing, feels like it belongs in the same conversation as what experiencers are actually reporting.
