Comment on "Comment on Galina Weinstein's article entitled 'Convergences and Divergences: Einstein Poincar\'e and Special Relativity' "

Abstract

This paper provides a systematic response to the criticisms raised by Jean-Marc Ginoux in response to my review of his book on the history of relativity. Whereas my review was written in a strictly academic manner, Ginoux's commentary intermingles mathematical objections with ad hominem insinuations about both Einstein and me. The purpose of this reply is twofold: first, to clarify the historiographical and conceptual issues at stake in the interpretation of Einstein's 1905 paper and Poincar\'e's contributions of 1905--1906; and second, to demonstrate why the conflation of algebraic form with conceptual content leads to distorted conclusions.
