Interesting point. But that's very weak evidence (because as I said the two known instances have significant differences). Also, this is a heuristic and produces many false positives.

At best it motivates me to remain open to arguments that there might be more kinds of 'truth', which I am. But the mere argument that there might be is not interesting, unless someone can provide an argument for a concrete example. Or even a suggestion of what a concrete example might be like.
