As George Steiner puts it, speaking eloquently of Heidegger: As knower and user, the ego is predator. For Heidegger, on the contrary, the human person and self-consciousness are not the centre, the assessors of existence. Man is only a privileged listener and respondent to existence. The vital relation to otherness is not, as for Cartesian and positivist rationalism, one of ‘grasping’ and pragmatic use. It is a relation of audition. We are trying ‘to listen to the voice of Being’. It is, or ought to be, a relation of extreme responsibility, custodianship, answerability to and for.30
