" Man obviously is a being. As such he belongs to the totality of Being—just like the stone, the tree, or the eagle. But man's distinctive feature lies in this, that he, as the being who thinks, is open to Being, face to face with Being; thus man remains referred to Being and so answers to it. Man is essentially this relationship of responding to Being, and he is only this. "

― Martin Heidegger , Identity and Difference
