He did not create a NEW art form because his life is art.
Everyone's life could be ART.Everyone's work coule be ART.
It's too cruel to be proud of creating a "art-work"and to be an "artist".Also,it's too cruel to discriminate artist/art work from "normal people" and "normal work".
There's no boundary between different genres of art.Because everything in this universe is connected.Everyone,every element is the extension of energy.
Art could be exist even no body knows/cares/sees/documents/record.
Art is an inner power and energy that could be presented/explored/showed/expressed by artists.
Art is the kingdom of freedom,love,happiness...any energy that support human-being to be one element of the whole universe.
Any notion of art form or classification is too catholic.
Duchamp not only provided the possibility of what art could be,also of what life could be in the whole.
That's why he has been mentioned so many times,over and over again.
Because there are so few people in this world can actually come over to break the rules to open the new world to the people.
Because he was the one who didn't care anything and enjoyed the whole life.
There's another sentence made me cry,wrote by Karlheinz Strockhausen
Imagine this,that I could create a work of art now and you all not only surprised,but you would fall down immediately,you would be dead and you would be reborn,because it is simply too insane.Some artists also try to cross the boundaries of what could ever be possible or imagined,TO WAKE US UP,TO OPEN ANOTHER WORLD FOR US!
