The article aims to highlight the cosmic dimension of Jean-Luc Nancy's thoughts on the sense of the world. It argues that his thought of the world is deeply touched by "cosmic stains." The cosmic dimension is to be understood as "stain" rather than as dimension insofar it is about the moment in which the sentiment that existence is really existing incides upon existence. It is about being touched by the there-is of the there-is itself. The cosmic stain of Nancy's thoughts of the sense of the world has to do with existence being "exscripted" from ontology when, in the state of the acosmism of the world today, the only thing to hold on to is the existence of existence, which opens a transitive sense of existence and being.
