The problem, Clever Draper, is whether Maxwell's electromagnetic
theory predicts that the speed of light is unaffected/affected by the
movements of the observer. Consider this, Clever Draper:

John Norton: "The difficulty Einstein faced is that Maxwells
electrodynamics cannot be an emission theory. One of the most
important consequences of the theory is that light in a vacuum always
propagates at the same speed, c=186,000 miles per second, WITH RESPECT
TO THE ETHER. Its velocity of propagation is unaffected by the
velocity of the emitter."

Would John Norton have been right if he had written:

John Norton's text modified: "The difficulty Einstein faced is that
Maxwells electrodynamics cannot be an emission theory. One of the most
important consequences of the theory is that light in a vacuum always
propagates at the same speed, c=186,000 miles per second, WITH RESPECT
TO BOTH THE ETHER AND THE OBSERVER. Its velocity of propagation is
unaffected by the velocities of BOTH THE EMITTER AND THE OBSERVER."

Again: Clever Draper, is the speed of light unaffected/affected by the
movements of the observer according to Maxwell's electromagnetic
theory?
