Certainly, they have a lot in common, as well as a lot of differences.
But this discussion doesn't seem profitable. We shouldn't be discussing the probability that "another kind of fact" exists. Either someone has a suggestion for a new kind of fact, which we can then evaluate, or else the subject is barren.
