Abstract
The community separates the world into the exterior and the interior world, and continuously suppresses and removes what has no meaning into the exterior world. In this thesis, I think of M.Duchamp as a person who would like to be in the exterior world and I also regard the scribbling of a child something in the exterior world. Also, I think the work of Duchamp and the scribbling of a child are impossible to put into words. Furthermore, they require infinite interpretation and should not be regarded as meaningless. I consider them not to be transcendent of this world, but to be familiar to us in our daily life. Moreover, these two sorts of exterior things make the possibility clear that they will nullify the system of community which divides the world into two parts; the interior and the exterior worlds. In other words, they can clearly show the world without the border.
