Read part one: 'Being and Time, part 1: Why Heidegger matters'.The relation between thinking things and extended things is one of knowledge and the philosophical and indeed scientific task consists in ensuring that what a later tradition called "subject" might have access to a world of objects. This is what we might call the epistemological construal of the relation between human beings and the world, where epistemology means "theory of knowledge". Heidegger does not deny the importance of knowledge, he simply denies its primacy. Prior to this dualistic picture of the relation between human beings and the world lies a deeper unity that he tries to capture in the formula "Dasein is being-in-the-world". What might that mean?
If the human being is really being-in-the-world, then this entails that the world itself is part of the fundamental constitution of what it means to be human. That is to say, I am not a free-floating self or ego facing a world of objects that stands over against me. Rather, for Heidegger, I am my world. The world is part and parcel of my being, of the fabric of my existence. We might capture the sense of Heidegger's thought here by thinking of Dasein not as a subject distinct from a world of objects, but as an experience of openedness where my being and that of the world are not distinguished for the most part. I am completely fascinated and absorbed by my world, not cut off from it in some sort of "mind" or what Heidegger calls "the cabinet of consciousness".
