Wilhelm Dilthey
Dasein as an intertwined subject/object cannot be separated from its objective "historicality," a concept Heidegger credits in the text to Wilhelm Dilthey. Dasein is "stretched along" temporally between birth and death, and thrown into its world; into its future "possibilities" which "Dasein" is charged with assuming. "Dasein's" access to this world and these possibilities is always via a history and a tradition-- or "world historicality".
