To my disappointment, however, I find that his comment relates to an article entitled “On the origins of Einstein’s light-velocity postulate,” whereas the title of my paper is “On Einstein’s distrust of the electromagnetic theory: The origin of the light-velocity postulate.” The crucial point of my paper is just “Einstein’s distrust of the electromagnetic theory.” In contrast, Darrigol holds in his paper entitled “The electromagnetic origins of relativity theory” that in order to study Einstein’s relativity “the intricate evolution of electrodynamics at the turn of the century is the optimal context.” Darrigol also errs in writing that, “According to Abiko, Einstein expressed a complete rejection of the ether when, in August 1899, he wrote to Maric ...” [italics added]; in fact, I wrote, “Evidently by 1899 Einstein questioned, if he had not already rejected, the existence of the ether” [italics added]. To come to substance, the relevant quotation from Einstein’s letter to Maric reads:
