According to Deleuze, following the footsteps of NIETZCHE, the process of return implies a selection of differences, which must be reduced to "differentiable," that is, elements that differentiate and identify being. It is during this process of spiral movement that being thought, affirming, and effectively is realized. It is in this process that art becomes present, presence and "difference". Art does not replicate itself. It processes its legacy, so that it can become continuously in the present.
