Today's Einsteinians glorify Einstein's logic ("Constant for one, and thus constant for all"):

"And then Einstein took it to the next level as only Einstein could: not only are the laws of motion the same in every inertial (jargon alert: "non-accelerating") reference frame, but all physics are the same. Including Maxwell's equations. Including Maxwell's speed of light. Which is a constant in one frame. And is thus constant in all frames. And there's our universal speed limit: the speed of light in a vacuum. Constant for one, and thus constant for all, no matter how fast you're moving."

Breathtaking isn't it?
