Back in the 20th century, when I was in college, a friend asked me to write an article for a journal he was starting. He asked me to write on the meaning of art. I didn't feel up to that task, so instead I wrote an essay defining the work of art in its late 20th century context. In it, I concluded that anything can be a work of art, provided you say it's a work of art and give it a title. I illustrated my point with this sculpture, by Picasso, which is my avatar. My essay did not meet with universal acclaim; one person exclaimed "Aw, bull! That's just old bike parts!" Whatever.
