Update: or for a little more substance, p.464:
"Taking place" is not a formality to which an event incidentally submits - it is the event's very being. World history consists of actual concrete happenings in a temporal sequence; it is not necessary or possible that happening should happen to them all over again. The system of the manifold is thus "complete" in something like the technical logical sense, and any attempted addition to it is bound to be either contradictory or supererogatory.
