There is art and then there is art, and standing between them is art.
By this I mean there is art that is created by the artist and there is art that is perceived by the audience. And between those two, the created and the perceived, is the piece of artwork. It can stand alone but always takes on meaning through creation and perception. And the meaning may not be the same for the artist and the audience. The work itself may or may not have an inherent meaning. You would have to ask the piece what it meant, and until a piece of art becomes sentient that question will remain a mystery. Certainly an artist may create with an intention and that intention may come across to the audience, they may “get it.” Artist’s aides such at titles, descriptions, biographies and philosophical methodological ponderings can all help the audience to “get it.” But certainly the audience also has the option to ignore all that and find their own meaning in the piece that has nothing to do with the intention of the artist. The meaning is then derived from their own experiences and psychological profile. But if the piece was wrapped up, stored away for a hundred years, all the descriptors lost from memory and then the piece was rediscovered it would still have meaning for those that found it. That is art.
