Aram D'Abro, The evolution of scientific thought from Newton to Einstein (1927)
“ When we consider the new views that are forced upon us by the theory [Pg 420] of relativity, we find that certain refinements are necessary. The special theory of relativity has shown that there was no reason to dispute the status of those qualities thought to be primary by classical science so long as we restricted our investigations to the points of view of observers at rest with respect to the object; but that when observers in relative motion were considered, it became impossible to effect a synthesis of all the apparent shapes so as to obtain one sole impersonal or real spatial shape. ”
