A couple of weeks ago I posted on PHILOS-L, a philosophy list with
4,853 subscribers, the following quotation:

http://listserv.liv.ac.uk/cgi-bin/wa?A2=ind0911&L=philos-l&T=0&O=D&P=50126
Peter Hayes "The Ideology of Relativity: The Case of the Clock
Paradox" : Social Epistemology, Volume 23, Issue 1 January 2009, pages
57-78.
"The triumph of relativity theory represents the triumph of ideology
not only in the profession of physics but also in the philosophy of
science."

Philosophers of science remained silent. For the sake of argument, let
us assume that they possess dignity which prevents them from
discussing Peter Hayes quoted by Pentcho Valev. The assumption is
wrong. In 2001 Jos Uffink, an influential philosopher of science,
published a text equivalent to "The triumph of thermodynamics
represents the triumph of ideology not only in the profession of
physics but also in the philosophy of science":

http://philsci-archive.pitt.edu/archive/00000313/
Jos Uffink: "This summary leads to the question whether it is fruitful
to see irreversibility or time-asymmetry as the essence of the second
law. Is it not more straightforward, in view of the unargued
statements of Kelvin, the bold claims of Clausius and the strained
attempts of Planck, to give up this idea? I believe that Ehrenfest-
Afanassjewa was right in her verdict that the discussion about the
arrow of time as expressed in the second law of the thermodynamics is
actually a RED HERRING."

For eight years no philosopher of science has discussed or even
referred to this text. Uffink himself seems to have forgotten it
completely. Another influential philosopher of science, John Norton,
published texts which, combined with a few other texts, suggests that
Einstein's 1905 false light postulate has in fact killed theoretical
physics. Other philosophers of science remained silent:

http://www.pitt.edu/~jdnorton/papers/companion.doc
John Norton: "Einstein could not see how to formulate a fully
relativistic electrodynamics merely using his new device of field
transformations. So he considered the possibility of modifying
Maxwell's electrodynamics in order to bring it into accord with an
emission theory of light, such as Newton had originally conceived.
There was some inevitability in these attempts, as long as he held to
classical (Galilean) kinematics. Imagine that some emitter sends out a
light beam at c. According to this kinematics, an observer who moves
past at v in the opposite direction, will see the emitter moving at v
and the light emitted at c+v. This last fact is the defining
characteristic of an emission theory of light: the velocity of the
emitter is added vectorially to the velocity of light emitted....If an
emission theory can be formulated as a field theory, it would seem to
be unable to determine the future course of processes from their state
in the present. AS LONG AS EINSTEIN EXPECTED A VIABLE THEORY LIGHT,
ELECTRICITY AND MAGNETISM TO BE A FIELD THEORY, these sorts of
objections would render an EMISSION THEORY OF LIGHT INADMISSIBLE."

http://philsci-archive.pitt.edu/archive/00001743/02/Norton.pdf
John Norton: "Einstein regarded the Michelson-Morley experiment as
evidence for the principle of relativity, whereas later writers almost
universally use it as support for the light postulate of special
relativity......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE
WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT
POSTULATE."

"Relativity and Its Roots" By Banesh Hoffmann
p.92: "Moreover, if light consists of particles, as Einstein had
suggested in his paper submitted just thirteen weeks before this one,
the second principle seems absurd: A stone thrown from a speeding
train can do far more damage than one thrown from a train at rest; the
speed of the particle is not independent of the motion of the object
emitting it. And if we take light to consist of particles and assume
that these particles obey Newton's laws, they will conform to
Newtonian relativity and thus automatically account for the null
result of the Michelson-Morley experiment without recourse to
contracting lengths, local time, or Lorentz transformations. Yet, as
we have seen, Einstein resisted the temptation to account for the null
result in terms of particles of light and simple, familiar Newtonian
ideas, and introduced as his second postulate something that was more
or less obvious when thought of in terms of waves in an ether."

Louis de Broglie: "Tout d'abord toute idée de "grain" se trouvait
expulsée de la théorie de la Lumière : celle-ci prenait la forme d'une
"théorie du champ" où le rayonnement était représenté par une
répartition continue dans l'espace de grandeurs évoluant continûment
au cours du temps sans qu'il fût possible de distinguer, dans les
domaines spatiaux au sein desquels évoluait le champ lumineux, de très
petites régions singulières où le champ serait très fortement
concentré et qui fournirait une image du type corpusculaire. Ce
caractère à la fois continu et ondulatoire de la lumière se trouvait
prendre une forme très précise dans la théorie de Maxwell où le champ
lumineux venait se confondre avec un certain type de champ
électromagnétique."

John Stachel: "Einstein discussed the other side of the particle-field
dualism - get rid of fields and just have particles."
Albert Einstein 1954: "I consider it entirely possible that physics
cannot be based upon the field concept, that is on continuous
structures. Then nothing will remain of my whole castle in the air,
including the theory of gravitation, but also nothing of the rest of
contemporary physics."
John Stachel's comment: "If I go down, everything goes down, ha ha,
hm, ha ha ha."

http://www.ekkehard-friebe.de/wallace.htm
Bryan Wallace: "Einstein's special relativity theory with his second
postulate that the speed of light in space is constant is the linchpin
that holds the whole range of modern physics theories together.
Shatter this postulate, and modern physics becomes an elaborate
farce!....The speed of light is c+v."

Recently John Norton suggested that the conclusion that the separation
between past, present and future is an illusion, a conclusion directly
following from Einstein's 1905 false light postulate, should be
abandoned. Other philosophers of science remained silent:

http://www.salem-news.com/articles/june232009/einstein_lessons_dj_6-22-09.php
"For those of us who believe in physics, this separation between past,
present and future is only an illusion, however tenacious" - Albert
Einstein

Brian Greene: "I certainly got very used to the idea of relativity,
and therefore I can go into that frame of mind without it seeming like
an effort. But I feel and think about the world as being organized
into past, present and future. I feel that the only moment in time
that's really real is this moment right now. And I feel [that what
happened a few moments ago] is gone, and the future is yet to be. It
still feels right to me. But I know in my mind intellectually that's
wrong. Relativity establishes that that picture of the universe is
wrong, and if I work hard, I can force myself to recognize the fallacy
in my view or thinking; but intuitively it's still what I feel. So
it's a daily struggle to keep in mind how the world works, and
juxtapose that with experience that [I get] a thousand, even million
times a day from ordinary comings and goings."

"General relativity knits together space, time and gravity.
Confounding all common sense, how time passes in Einstein's universe
depends on what you are doing and where you are. Clocks run faster
when the pull of gravity is weaker, so if you live up a skyscraper you
age ever so slightly faster than you would if you lived on the ground
floor, where Earth's gravitational tug is stronger. "General
relativity completely changed our understanding of time," says Carlo
Rovelli, a theoretical physicist at the University of the
Mediterranean in Marseille, France.....It is still not clear who is
right, says John Norton, a philosopher based at the University of
Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his
instinct - and the consensus in physics - seems to be that space and
time exist on their own. The trouble with this idea, though, is that
it doesn't sit well with relativity, which describes space-time as a
malleable fabric whose geometry can be changed by the gravity of
stars, planets and matter."

http://www.pitt.edu/~jdnorton/Goodies/passage/index.html
John Norton, 1 Mar 2009: "A common belief among philosophers of
physics is that the passage of time of ordinary experience is merely
an illusion. The idea is seductive since it explains away the awkward
fact that our best physical theories of space and time have yet to
capture this passage. I urge that we should resist the idea. We know
what illusions are like and how to detect them. Passage exhibits no
sign of being an illusion....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 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. There are temporal orderings. We can identify earlier and
later stages of temporal processes and everything in between. What we
cannot find is a passing of those stages that recapitulates the
presentation of the successive moments to our consciousness, all
centered on the one preferred moment of "now." At first, that seems
like an extraordinary lacuna. It is, it would seem, a failure of our
best physical theories of time to capture one of time's most important
properties. However the longer one works with the physics, the less
worrisome it becomes....I was, I confess, a happy and contented
believer that passage is an illusion. It did bother me a little that
we seemed to have no idea of just how the news of the moments of time
gets to be rationed to consciousness in such rigid doses.....Now
consider the passage of time. Is there a comparable reason in the
known physics of space and time to dismiss it as an illusion? I know
of none. The only stimulus is a negative one. We don't find passage in
our present theories and we would like to preserve the vanity that our
physical theories of time have captured all the important facts of
time. So we protect our vanity by the stratagem of dismissing passage
as an illusion."
