 Some philosophers object that Leftow’s time-travel analogy is unhelpful because time-travel is impossible (Hasker 2009, 158). Similarly, one may object that Leftow is trying to illuminate the obscure (the Trinity) by the equally or more obscure (the alleged possibility of time travel, and timeless analogues to it). If Leftow’s one-self theory is intended as a literal interpretation of trinitarian language, a “rational reconstruction” (Tuggy 2011a), this would be problematic; but if he means it merely as an apologetic defense (i.e. we can’t rule out that the Trinity means this, and this can’t be proven incoherent) then the fact that some intellectuals believe in the possibility of time travel supports his case.
