May I also note (although I hesitate as this is already a full node) that
Nietzsche used this "..." to finish off some statements in his books, as a mark to point out that this train of thought had no real ending, or to state that there was no more he could say about it. He used in a rather strange fashion though, to end a statement on a
ambiguous note.
I just wanted to point out that the use of "..." is not a new invention but was used in the 1800's!
