Some believe the modernist movement of the late 19th and early  20th centuries were the final cohesive chapter in the 
culmination of linear history, that post-modernism was ushered 
in following WWII and that philosophical and aesthetic movements ceased to develop according to linear trajectories, and instead diverged into a multifold network of parallel and intersecting paths.  

Ghostmodernism is the end of these paths. A new beginning.
