It would seem rather pedantic for an expert in physics to tell us, first, that our crude generalization about falling bodies is absolutely false because there are facts (as there are) which disagree with it; and, second, that therefore we have no right, on the basis of such falsity, to step aside from the path of the stone. This, however, is just the way that some of the academic experts reason and advise about social matters.
So that was happening even then...
