In grappling with the question of being Heidegger chooses to look at the being who has an understanding of being: human being. In so looking, Heidegger asserts that a human being is a being-in-the-world. It is tempting to interpret this as meaning that the world is a container, say a glass, and the human being is in the world, as water is in a glass. Wrong! A more accurate representation is to see a tapestry and a human being is one thread in the tapestry. Notice, there is not a thread isolated from the tapestry – the two are one!
