Jaspers’ concept of Dasein is sometimes mistakenly confused with the concept of Dasein in Heidegger, which is better known. This has determined the article purpose – to investigate and to analyze the concept of Dasein in the philosophy of Jaspers who, like Heidegger, has created a new meaning of the word Dasein, which did not exist before in German philosophy. Before being interested in philosophy Jaspers used in his texts the word Dasein in its traditional meaning of the existence of any entity. In his philosophical concept Jaspers generally used the concept of Dasein in the meaning of the way of existence of any living entity. But in periechontology, the doctrine of all-embracing, Jaspers has limited the notion of Dasein by the meaning of only human existence, which along with the consciousness in general, spirit and existence, is one of the ways of the elucidation of all-embracing through a man.
