All this borrowing was purportedly to symbolise the collapse of "grand narratives" by which western civilisation had buttressed its own authority. This problematising of supposed over-confidence was instead a sign of increasing inconfidence, rather like a golfer disassembling his swing pretends he's only improving things rather than trying to make sense of the yips that have destroyed it. Structuralism leading to post-structuralism and the compulsively subversive practice of deconstruction was a similar decline from a practised easy swing of a civilisation in full flow to a nervous picking away at the seams trying to work out why everything is falling apart. Modern art's move to abstraction also traced a decline like a malfunctioning graphics card which no longer has the resource to put textures on its polygons.
