With the rise of the very general movement of Modernity in the West--riding as it did on the mental worldview, with its replacement of mythic themes with themes dominated by nature, by realism, by impressionism, by subjective expressionism, and by abstract expressionism.  And with the general rise of Postmodernism, we see those trends carried even further into the existential worldspace, where multiple perspectives, at first a source of endless creativity, soon became a paralyzing nightmare of infinite jest, met with infinite irony.
