We spent many a lunch time walking for exercise, during which time he was my sounding board, that was the price he paid for a walking partner. I wanted to be able to say that because of these criteria this design on a pot produced 20,000 years ago is art and and according to the same criteria this abstract painting produced today is also art. Having spent decades trying to understand art, and having found thousands of egos clashing over turf definitions that have more to do with product marketing than with an attempt to understand art. Acrylic painting is inferior to oil painting and drawing is the most inferior of all. I have seen as much art in an Abstract painting as I have seen in a traditional Representational painting.
Art is absolutly and catagorically independent of media and style.
All differences are promoted by people interested in money and ego.
