Abstract
In this article, I establish first the critical role of conscience in Heidegger's Being and Time . As the call of care, conscience attests to the authenticity of Da-sein as it discloses and "accomplishes" Da-sein as the being it is delivered over to be. Heidegger's interpretation of conscience also epitomizes the central aporias of Being and Time , which, with a view to revoking the Western metaphysical tradition, ultimately recalls it. At the heart of such aporias is the hermeneutic circle in the attestation of conscience, whose voice only "reaches him who wants to be brought back." While the language of conscience and attestation was put away in Heidegger's later writings, I argue that the question concerning conscience is a leading question that will continue to guide us to build our way back and forth
