Actually, early empiricists wanted to consider tautologies just those that were confirmed by any evidence whatsoever. (This enables an empiricist to have a pure evidential base of only empirical events.) It doesn't sound great, but some folks like the conclusion that anything (or anything possible) is evidence for a tautology.
