 Third, what role, if any, is special relativity playing in the proposal? The intended role is a considerable one. Considerations of the relativity of simultaneity are supposed to show that the difficulties with the notion of ET-simultaneity are “by no means unique” and “cannot be assumed to be difficulties in the concepts of ET-simultaneity or of eternity themselves” (S&amp;K 1981: 439). But it is hard to see how they could show this. Stump and Kretzmann emphasize the finding that simultaneity is a three-place relation and present it as a response to a threat of incoherence (two distant events being both “simultaneous […] and not simultaneous” (S&amp;K 1981: 437)).  But the difficulties with ET-simultaneity arise whether it is two-place or three-place. They pertain to spelling out what an eternal present and the unique eternal frame of reference might be, and how there can be causal relations, including observational ones, between a being in it and us. No comparable difficulties are involved in special relativity (Fales 1997; also Padgett 1992: 71; Craig 2009).
