Martin Heidegger employs in Being and time´s section 14 the term depriving the world of its worldhood to characterize the stance adopted by the tradition of philosophy to think about the beings. In this posture, the world is interpreted as being present at hand, based on a privilege of the cognitive mode of relationship with them. Our aim, however, is not restricted to an elucidation of this mode of thinking the world depriving it indicated by Heidegger, but investigate why this mode predominates in philosophy as a whole, in the previous ontology. From the realization that the cognitive attitude has its roots and reasons in an essential way of being that ourselves are, of Dasein, called being-in-theworld, we pose the question: in what sense Heidegger uses the term depriving the world to characterize an approach to the being based on being-in-the world? Through the investigation of issues in Being and time´s division one, we emphasize this question, assuming that it affects the main issue of this Heidegger´s text, the question of the meaning of being.
