As soon as I received my note back from the list I find a blunder:
I meant to write:
"To assert that verb forms which make visible the end of an event *in
discourse* are perfective is not to force an issue(if that's what you mean
by "brute
facts") or to lean on analysis of discourse to our hurt. On the contrary,
it is a fact(the "institutional" kind ;-) )."
I forgot the words "are perfective" in my original.
