Not sure what this is yet…but I think its going to become something…
Modern art removes, the creation of and interaction with, art from the Academy and the elite and places the production of and interaction with art into the realm of the every day and every one (see Graffiti, Warhol’s Soup Cans and Brillo Boxes, Keith Haring murals, etc.).
Postmodernism takes and removes the Truth from the realm of the elite (the Church, academics, powerful, colonialists) and places it in the hands of all. Subjectivity is not a scattering or shattering of TRUTH but a democratization where the truth is now in the hands of and the responsibility if the masses. In the same way of art.
People like Francis Schaeffer and H.R. Rookmaker were hoping to maintain art/faith/philosophy in the hands of the elite and faithful bourgeois. That is why they rail against Postmodern thinking and Postmodern art. They misunderstand that God for the powerful. When he is for all people.
In both art and culture, and our theo/philosophy, we are responsible now to create, not just view. We are responsible for truth, not just waiting to have knowledge passed down.
Our way of knowing, and what we know, and how we know is no longer handed down to us from the priest or the professor but can be known by all. Subjectivity gives us all a stake in the game. Modern art puts the power to comment, create and beautify in the hands of the everyday folk (not the grand or rich pantheons of culture mostly distant from most).
