 Craig responds that Morriston is really attacking his notion of a potential infinite by claiming that no relevant distinction exists between a potential and an actual infinite. But this, he says, rests on confusing an A-theory with a B-theory of time. An infinite directed toward the future would be actual only on a B-theory of time, but not on an A-theory (Craig 2010: 452–53). On an A-theory of time, a change of tense makes a difference. That something actually has happened differs significantly from what may (even if determined) happen.
