But I just described two kinds of subject matter that are the only two kinds of subject matter I know about: physical facts and mathematical facts. "What should be done with the universe" invokes a criterion of preference, "should", which compels humans but not Babyeaters. If you look at the fact that the Babyeaters are out trying to make a different sort of universe, and the fact that the humans are out trying to make the universe make the way it should look, and you call these two facts a "disagreement", I don't understand what physical fact or logical fact is supposed to be the common subject matter which is being referred-to. They do the babyeating thing, we do the right thing; that's not a subject matter.
Mm... I can agree that a treaty has subject matter and is talked about by both parties, and refers to subsequent physical events. It has a treaty-kept-condition which is not quite the same thing as its being "true". (Note: in the original story, no treaty was actually discussed with the Babyeaters.) Where does that put it on a fact/opinion chart?
