Being and Time

Even if we join them together, we still do not get anything like the 'world' as their sum. If, then, we start with the Being of these entities, is there any avenue that will lead us to exhibiting the phenomenon of the world?1


¶ 16. How the Worldly Character of the Environment Announces itself in Entities Within-the-world1

The world itself is not an entity within-the-world; and yet it is so determinative for such entities that only in so far as 'there is' a world can they be encountered and show themselves, in their Being, as entities which have been discovered. But in what way 'is there' a world? If Dasein is ontically constituted by Being-in-the-World, and if an understanding of the Being of its Self belongs just as essentially to its Being, no matter how indefinite that understanding may be, then does not Dasein have an understanding of the world—a pre-ontological understanding, which indeed can and does get along without explicit ontological insights? With those entities which are encountered within-the-world-that is to say, with their character as within-the-world-does not something like the world show itself for concernful Being-in-the-world? Do we not have a pre-phenomenological glimpse of this phenomenon? Do we not always have such a glimpse of it, without having to take it as a theme for ontological Interpretation? Has Dasein itself, in the range of its concernful absorption in equipment ready-to-hand, a possibility of Being in which the worldhood of those entities within-the-world with which it is concerned is, in a certain way, lit up for it, along with those entities themselves?

If such possibilities of Being for Dasein can be exhibited within its concernful dealings, then the way lies open for studying the phenomenon which is thus lit up, and for attempting to 'hold it at bay', as it were, and to interrogate it as to those structures which show themselves therein.

[73] To the everydayness of Being-in-the-world there belong certain modes of concern. These permit the entities with which we concern ourselves to be encountered in such a way that the worldly character of what is within-the-world comes to the fore. When we concern ourselves with something, the entities which are most closely ready-to-hand may be met as something unusable, not properly adapted for the use we have decided upon. The tool turns out to be damaged, or the material unsuitable. In each of these cases equipment is here, ready-to-hand. We discover its unusability, however, not by looking at it and establishing its properties, but rather by the circumspection of the dealings in which we use it. When its unusability is thus discovered, equipment becomes conspicuous. This conspicuousness presents the ready-to-hand equipment as in a certain un-readiness-to-hand.
