Where Heidegger talks about “world” he will often appear to be talking about a pervasive interpretation or point of view which we bring to the things of the world. This, in any case, has been the view of many commentators. But there is little sense in speaking of “a point of view” here since precisely what Heidegger wants to indicate with the concept is that none other is possible. And there is no more sense in speaking of an interpretation when, instead of an interpretation, the “world” is meant to be that which can keep us from seeing, or force us to see, that what we have is one. Heidegger’s concept is quite like Kierkegaard’s “sphere of existence” and Wittgenstein’s “form of life,” and, as with them, it enters his inquiry only at its limits, when a problem moves out of his depth, or jurisdiction.
