Duchamp's Fountain

This piece was the subject of a huge debate in class last week, even sparking my interest when I usually find it hard to get engaged during class. The debate was on whether or not Duchamp's Fountain is even art. Some argues that there is no way that it could be art, it took no creativity and he did not intend for it to be art, he just wanted to test the art world and see how many people fell for this.

My argument is that those reasons actually make it art. It looks like it took no creativity to just put some words on a urinal and display it, but in order to come up with the original idea in the first place, it would have taken some creativity. And the fact that he was testing the limits of the art world makes this piece art as well. Just because some people do not like or understand the motives of this piece, does not make it art.

My question for you is whether or not you think Fountain is art? Does the fact that people test the limits of the art world make their pieces lesser or not art?
