## Abstract

A slightly modified version of the 1962 critique by philosopher Melbourne Evans (Emeritus, Univ. of New Mexico) shows that (I) in the famous moving train thought experiment he used to introduce his spatial theory of relativity, Einstein reached his result of relative simultaneity only by contradicting himself within the same chain of reasoning; and furthermore that (2) avoiding such a contradiction will lead inevitably to __absolute__ simultaneity, whatever velocity is attributed to light. As shown in a 1968 book by Rosser, another kind of attempt to validate relative simultaneity, a mathematical "proof' based on the Lorentz transformations, rests entirely on an invalid shift in meaning of certain mathematical symbols - which at first designate __lengths__. and then surreptitiously are reassigned to designate __points__.
