How can one view art philosophically?

Philosophy can be defined in many ways, in my opinion it all depends on who you ask and what their views are. It is said that philosophy is a way to think about a topic open mindedly and critically, without subjecting yourself to bias. I believe that in this century many of the bias that we have acquired are due to what we have be taught. So therefore in order to view art philosophically we have to push aside those views and become more open minded. I know this may be hard for many of you out there but trust me it can be done. Anyways, overall in my opinion viewing art philosophically is a way for one to take all views and opinions on a certain work of art and analyze them, and then truly understand the purpose and meaning of the work of art that was produced. So I pose this question, Without a philosophical view on art how would the art world be interpreted by those who are truly ignorant to its purpose?
