time this fact of skipping over the phenomenon of worldiness indicates that special measures are necessary in order to gain the correct phenomenal point of departure for access to that phenomenon, a point of departure which does not permit any skipping over.
The methodological directive for this has already been given. Being-in-the-world, and thus the world as well, must be the subject of our analytic in the horizon of average everydayness as the nearest kind of being of Dasein. We shall pursue everyday being-in-the-world. With it as a phenomenal support, something like world must come into view.
The closest world of everyday Dasein is the surrounding world [Umwelt]. Our investigation will follow the path from this existential character of average being-in-the-world to the idea of worldliness as such. We shall seek the worldliness of the surrounding world (environmentality [Umweltlichkeit]) by way of an ontological interpretation of those beings initially encountered within the surroundings. The expression surrounding world [Umwelt] contains a reference to spatiality in its component "around" ["Um"]. The quality of "around" ["Umherum"] which is constitutive for the surrounding world does not, however, have a primarily "spatial" meaning. Rather, the spatial character which uncontestably belongs to a surrounding world can be clarified only on the basis of the structure of worldliness. Here the spatiality of Dasein mentioned in § 12 becomes phenomenally visible. But ontology has tried precisely to interpret the being of the "world" as res extensa on the basis of spatiality. The most extreme tendency toward such an ontology of the "world," an ontology which is oriented in the opposite direction, that is to the res cogitans which is neither ontically nor ontologically identical with Dasein, is to be found in Descartes. The analysis of worldliness attempted here becomes clearer if we show how it differs from such an ontological tendency. It has three stages: (A) An analysis of environmentality and worldliness in general. (B) An illustrative contrast between our analysis of worldliness and Descartes' ontology of the "world." (C) The aroundness [Umhafte] of the surrounding world and the "spatiality" of Dasein.

§ 15. The Being of Beings Encountered in the Surrounding World
The phenomenological exhibition of the being of beings encountered nearest to us can be accomplished under the guidance of the everyday being-in-the-world, which we also call dealings in [Umgang in] [67] the world with innerworldly beings. Such dealings are already dispersed
