Heuristics in Einstein's Special Theory of Relativity

Recently John Norton suggested that "the passage of time is an
illusion" is a mistaken conclusion "from the work of Einstein,
Minkowski and many more" so perhaps he is now going to identify the
exact heuristics that led to this mistaken conclusion:

John Norton: "It is common to dismiss the passage of time as illusory
since its passage has not been captured within modern physical
theories. I argue that this is a mistake. Other than the awkward fact
that it does not appear in our physics, there is no indication that
the passage of time is an illusion. (...) The passage of time is a
real, objective fact that obtains in the world independently of us.
How, you may wonder, could we think anything else? One possibility is
that we might think that the passage of time is some sort of illusion,
an artifact of the peculiar way that our brains interact with the
world. Indeed that is just what you might think if you have spent a
lot of time reading modern physics. Following from the work of
Einstein, Minkowski and many more, physics has given a wonderfully
powerful conception of space and time. Relativity theory, in its most
perspicacious form, melds space and time together to form a four-
dimensional spacetime. The study of motion in space and all other
processes that unfold in them merely reduce to the study of an odd
sort of geometry that prevails in spacetime. In many ways, time turns
out to be just like space. In this spacetime geometry, there are
differences between space and time. But a difference that somehow
captures the passage of time is not to be found. There is no passage
of time."

Norton will surely give the rallying cry "Back to Newton" in the end.
Hopefully he will directly vindicate Newton's emission theory of light
paying no attention to his brother Einsteinian Craig Callender who is
desperately crying "Back to Newton through Lorentz":

Craig Callender: "Einstein mounted the next assault by doing away with
the idea of absolute simultaneity. According to his special theory of
relativity, what events are happening at the same time depends on how
fast you are going. The true arena of events is not time or space, but
their union: spacetime. Two observers moving at different velocities
disagree on when and where an event occurs, but they agree on its
spacetime location. Space and time are secondary concepts that, as
mathematician Hermann Minkowski, who had been one of Einstein's
university professors, famously declared, "are doomed to fade away
into mere shadows." And things only get worse in 1915 with Einstein's
general theory of relativity, which extends special relativity to
situations where the force of gravity operates. Gravity distorts time,
so that a second's passage here may not mean the same thing as a
second's passage there. Only in rare cases is it possible to
synchronize clocks and have them stay synchronized, even in principle.
You cannot generally think of the world as unfolding, tick by tick,
according to a single time parameter. In extreme situations, the world
might not be carvable into instants of time at all. It then becomes
impossible to say that an event happened before or after another."

Einstein, Relativity and Absolute Simultaneity (Routledge Studies in
Contemporary Philosophy)
"Einstein, Relativity and Absolute Simultaneity is an anthology of
original essays by an international team of leading philosophers and
physicists who, on the centenary of Albert Einsteins Special Theory of
Relativity, come together in this volume to reassess the contemporary
paradigm of the relativistic concept of time. A great deal has changed
since 1905 when Einstein proposed his Special Theory of Relativity,
and this book offers a fresh reassessment of Special Relativitys
relativistic concept of time in terms of epistemology, metaphysics and
physics. There is no other book like this available; hence
philosophers and scientists across the world will welcome its
publication."
"UNFORTUNATELY FOR EINSTEIN'S SPECIAL RELATIVITY, HOWEVER, ITS
EPISTEMOLOGICAL AND ONTOLOGICAL ASSUMPTIONS ARE NOW SEEN TO BE
QUESTIONABLE, UNJUSTIFIED, FALSE, PERHAPS EVEN ILLOGICAL."
Craig Callender: "In my opinion, by far the best way for the tenser to
respond to Putnam et al is to adopt the Lorentz 1915 interpretation of
time dilation and Fitzgerald contraction. Lorentz attributed these
effects (and hence the famous null results regarding an aether) to the
Lorentz invariance of the dynamical laws governing matter and
radiation, not to spacetime structure. On this view, Lorentz
invariance is not a spacetime symmetry but a dynamical symmetry, and
the special relativistic effects of dilation and contraction are not
purely kinematical. The background spacetime is Newtonian or neo-
Newtonian, not Minkowskian. Both Newtonian and neo-Newtonian spacetime
include a global absolute simultaneity among their invariant
structures (with Newtonian spacetime singling out one of neo-Newtonian
spacetimes many preferred inertial frames as the rest frame). On this
picture, there is no relativity of simultaneity and spacetime is
uniquely decomposable into space and time."
