  1. In a recent paper in this journal, McCall and Lowe (2003) argue that an understanding of Special Relativity reveals that the A theorist's notion of temporal passage is consistent with the B theory of time. They arrive at this conclusion by considering the twins' paradox, where one of two twins (T) travels to Alpha Centauri and back and upon her return has aged 30 years, while her earth-bound twin (S) has aged 40 years.
  2. Conclusion: What this shows is that we can define up a notion of temporal passage that is consistent with the B theory, but this notion is not one that the A theorist would accept as genuine temporal passage. So we cannot, I am afraid, have our cake and eat it too.
