Elephants can brush paint onto paper. Some of those painted pieces of paper sell for thousands. Art critics enthuse about some of the items they produce. Is it art because a critic says it's art? Is it art because the elephant had to learn to create an image using paint and brush, gradually making more complex images and developing a distinctive and recognisable style? Or is it art because, for some people, it has an emotional impact?

If those pictures /are/ art, and if those elephants had to learn to use a mouse and pose dials instead, would that mean the images weren't art any more?

As to my own opinion- if a picture, or a play, or a film, or a book, or a piece of music 'speaks' to me, so that I forget what media was used to create it, forget that I'm looking, or listening, or reading, and feel as if I'm actually there, then that's art.
