In that case, I believe that the question of whether or not art should have meaning is moot. I feel that once the piece is created, it has fulfilled its purpose as an expression of meaningfulness for the creators .. like a form of "living in the moment". Again though, it's very subjective, and I am just a pleb with my own appreciation for the human condition that is "the journey".

A friend of mine likes to create a piece, he looks at it for a few weeks, then he has to give it away .. for him, the piece represents a part of himself that he doesn't want to recognise, or has moved beyond, and so the meaning he gave to it is now lost to him.
