"The history of the concept of time is the history of the discovery of time and the history of its conceptual interpretation. ...it is the history of the question of the being of entities, the history of the attempts to uncover entities in their being, borne by the particular understanding of time, by the particular level of conceptual elaboration of the phenomenon of time. Hence, in the end, the history of the concept of time is more accurately the history of the decline and the history of the distortion of the basic question of scientific research into the being of entities. It is the history of the incapacity to pose the question of being in a radically new way and to work out its fundamentals anew—an incapacity which is grounded in the being of Dasein."
