The article compares Kierkegaard’s and Marcel’s comprehension of existence and communication of existence. With reference to the notion of existence, both authors (independently from each other) develop the idea of a second reflection that includes a theory of communication. But whereas Kierkegaard conceives communication strictly within a first person perspective, Marcel establishes a kind of second person perspective. For this reason and despite a strong common basis in their views, different aspects of communication of existence are put forward by them.
