What the word for space, Raum, Rum, designated is said by its ancient meaning. Raum means a place cleared or freed from settlement and lodging. A space is something that has been made room for, something that is cleared and free, namely within a boundary, Greek peras. A boundary is not that at which something stops, but as the Greeks recognized, the boundary is that from which something begins its presencing. That is why the concept is that of horismos, that is, the horizon, the boundary. Space is an essence that for which room has been made, that which is let into its bounds, that for which room is made is always granted and hence is joined, that is, gathered, by virtue of a location, that is, by such a thing as the bridge. Accordingly, spaces receive their being from location and not from “space.”
Things which, as locations, allow a site we know in anticipation call buildings. They are so called because they are made by a process of building construction. Of what sort this making—building—must be, however, we find out only after we have first given thought to the nature of those things which of themselves require building as the process by which we are made. These things are locations that allow a site for the fourfold, a site that each case provides for a space. The relation between location and space lies in the nature of these things qua locations, but so does the relation of the location to the man who lives at that location.
