So strong was the preconception of absolute space and time in the scientific mentality of those days, that Lorentz did not realize the grand transcendence of what he had discovered, and contented himself with remodeling the edifice of Physics -- instead of rebuilding it with a new foundation.

Truth is not as pompous and romantic as myth ... but it has the immeasurable value of being the Truth.
Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously considers it as a state of higher knowledge.
There is no problem more difficult to solve than that created by ourselves.
To believe in nothing is as ridiculous as to believe in everything. Reason and factual evidence may convert a belief into knowledge.
One of the various theories proposed to explain the negative result of the famous Michelson-Morley experiment with light waves (conceived to measure the absolute space), was based on the ballistic hypothesis, i.e. on postulating that the speed of light predicted by Maxwell's equations was not given as relative to the medium but as relative to the transmitter (firearm). Had that been the case, the experiment negative results would have not caused such perplexity and frustration (as we shall see in forthcoming sections).
The objective and merit of Einstein's theory is to identify those physical magnitudes which are absolute, i.e. common for all Inertial Frames, distinguishing them from those which are a mere perspective, only shared by those observers in repose within a given Inertial Frame.
The notion of Local Inertial Frame is crucial to understanding Nature and, in particular, General Relativity. Notwithstanding, very few popular science books (not even textbooks) emphasize enough its fundamental character.
The existence of both ( and ) depends upon the context created by our thoughts, our language, our theories, and our interaction (experimentation) with our external world.
It is curious that the human mind could blindly accept an infinite speed but had reservations to accept a finite one, simply because it was too large!
It is worth noting that a wrong folkoric definition of an Inertial Frame in the Popular Science literature (even in text books) reads that 'it is a frame in uniform motion'. We know very well by now that the idea of motion requires a frame of reference, so that such a definition of an Inertial Frame has no meaning whatsoever, confusing the reader because it tacitly reaffirms the idea of absolute motion -- when the goal of every didactic exposition of Relativity Theory should be precisely the opposite.
When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!
Swiftness is the enemy of comprehension.
... One can know very much but comprehend very little and, besides, ... different objectives require different levels of knowledge - though always with the maximum possible comprehension suited to the purpose.
The difference between Lorentz's Transformation in Lorentz's theory and Lorentz's Transformation in Einstein's Special Relativity is not mathematical but ontological and epistemological and, being so, it was to be expected the emergence of historians, scientists, and philosophers that, not having understood in depth the philosophical content and transcendence of the theory, would minimize Einstein's contribution.
Teaching the layperson (divulgare) is not distorting (tergiversare) the subject, but educating the public; and it is our duty as scientists to educate without distorting the essence of the scientific knowledge attained by humanity. The future of our society depends upon this premise.
It is not the reverence for words, but for their that determines our deepness of comprehension of a given assertion about Nature.
Subjectivity is strange to Science, while Relativity is an objective part of it.
The command of our language is crucial to focusing our thoughts and communicating them with precision to others.
The past and the future are not a collection of instants shared by all space, but a collection of events that correspond to a possible relation of causal order with the present event.
