Heidegger put special emphasis on the role of Dasein in enabling the being of entities to come to presence and manifest itself, by providing the 'clearing' in which entities can show up as entities. In case this all sounds a little too anthropocentric however, Zimmerman reminds us that Dasein did not own or produce this clearing, but rather is appropriated as this clearing. Dasein is in this fashion summoned by being and finds itself always already thrown into the world of entities and the ontological play of concealing and unconcealing. Authentic Dasein denotes a kind of embodied being-in-the-world whose essence is 'care', where 'to care' refers not only to ontic intervention but principally to the simple 'letting be' of entities; of not submitting them all the time to the calculating reason of human subjectivity. Authentic Dasein can be seen in this way as the 'shepherd of being'.
