The Barnes Foundation and Intellectual Property

I would like to focus on intellectual property and human rights in my upcoming paper. I will be reading some of the novel Intellectual Property and Human Development and I will be exploring utilitarian arguments concerning intellectual property. While watching The Art of Steal I thought about one of the proponent's (of the move of the Barnes Foundation) arguments: that art should be accessible to large groups of people. Although the film did not emphasize this argument, the argument is a good one, and at the core of it are the issues of intellectual property and human rights. So, is art the property of the person who buys it? Or, is it human property? Since Van Gogh's art influences massive amounts of people, does it belong to humanity or to the sole owner of the Van Gogh? I think it would be a mighty feat to answer these questions and I doubt I'll be able to do it. But, I hope to explore these issues and the questions they raise.
