Postmodern art often focuses on everyday subjects from consumer and popular culture. (Like the Campbell’s soup cans depicted by Warhol.) This burrs the line between high and low culture.
"In postmodernism, the effacement in it of some key boundaries or separations, most notable the erosion of the older distinction between high culture and so-called mass or popular culture. This is perhaps the most distressing development of all from an academic standpoint, which has traditionally had a vested interest in preserving a realm of high or elite culture against the surrounding environment of philistinism."
- Fredric Jameson
Throughout university, when studying English and Mass Communication, I have watched the elitism of 'good art' dissolve and have taken classes where I studied, in depth, Science Fiction, Television, Comic Books, etc.
"It's a way, above all, to justify oneself in preferring less demanding art without being called reactionary or retarded (which is the greatest fear of the newfangled philistines of advancedness)."
- Clement Greenberg
Dang, looks like academics are starting to catch on to my lazy philistine ways.
"Philistine - 1) A person who is lacking in, hostile, or smugly indifferent to cultural values, intellectual pursuits, aesthetic refinement, etc. 2) A person who is contentedly commonplace in ideas and tastes."
