‘The world’ examines how Dasein understands the world. Dasein needs a world populated with entities for it to engage with; it sees these entities primarily as objects of use. Different entities relate to each other and form a significant whole. The world is seen in terms of a web of significance in which things have their rightful places. Much of it is normally inconspicuous. Certain features of this understanding, like spatiality and the self, are known a priori and Dasein’s world is a public world accessible to others. Understanding the world displays possibilities, but requires a ‘fore-structure’ to start from. Moods can affect this understanding and reveal the world differently.
