"Herbert Dingle (2 August 1890 - 4 September 1978), an English
physicist and natural philosopher, who served as president of the
Royal Astronomical Society from 1951 to 1953 (...) He was one of the
founders of the British Society for the History of Science, and served
as President from 1955 to 1957. He founded what later became the
British Society for the Philosophy of Science as well as its journal,
the British Journal for The Philosophy of Science."

Herbert Dingle, SCIENCE AT THE CROSSROADS
p.27: "According to the special relativity theory, as expounded by
Einstein in his original paper, two similar, regularly-running clocks,
A and B, in uniform relative motion, must work at different
rates.....How is the slower-working clock distinguished? The
supposition that the theory merely requires each clock to APPEAR to
work more slowly from the point of view of the other is ruled out not
only by its many applications and by the fact that the theory would
then be useless in practice, but also by Einstein's own examples, of
which it is sufficient to cite the one best known and most often
claimed to have been indirectly established by experiment, viz.
'Thence' [i.e. from the theory he had just expounded, which takes no
account of possible effects of accleration, gravitation, or any
difference at all between the clocks except their state of uniform
motion] 'we conclude that a balance-clock at the equator must go more
slowly, by a very small amount, than a precisely similar clock
situated at one of the poles under otherwise identical conditions.'
Applied to this example, the question is: what entitled Einstein to
conclude FROM HIS THEORY that the equatorial, and not the polar, clock
worked more slowly?"

Another version of the same question:

Theory.  1920.

Reference

What entitled Einstein to conclude FROM LORENTZ TRANSFORMS ALONE
("Section XII") that the clock at the centre of the disc runs faster
than the clock at the edge of the disc? How can Lorentz transforms
predict both reciprocal and non-reciprocal time dilation?
