What is contemporary art?

What classifies as "good" modern/contemporary art?

• I've seen some of the works of art in modern museums such as moma, or the Tate modern. I've never understood what made the pieces so special (damien Hearst and his dots! Really??). Although I do realize this is a broad question, can anyone explain to me what makes a work of contemporary or modern art museum worthy.

• Answer:

  Nope, the only value that art has is that which is bestowed upon it. Obviously there are techniques and styles - and masters of those styles and the social, political, and historical contexts...blah, blah, blah - art is the manifestation of emotion and feeling. I suppose what makes a particular piece museum worthy would be the social, political, and historical contexts of the work.
