One such test is the test for paradoxes arising from one or more
postulates. For example, the following two postulates lead to a
paradox, meaning that not all the postulates are correct:

1. Statement 2 is true.
2. Statement 1 is false.

The paradox that arises from the postulates of Einstein's
"Electrodynamics of Moving Bodies" can be described as follows:

"Examples of this sort, together with the unsuccessful attempts to
discover
any motion of the earth relatively to the ?light medium,? suggest that
the
phenomena of electrodynamics as well as of mechanics possess no
properties
corresponding to the idea of absolute rest. They suggest rather that,
as has
already been shown to the first order of small quantities, the same
laws of
electrodynamics and optics will be valid for all frames of reference
for which the
equations of mechanics hold good.1 We will raise this conjecture (the
purport
of which will hereafter be called the ?Principle of Relativity?) to
the status
of a postulate, and also introduce another postulate, which is only
apparently
irreconcilable with the former, namely, that light is always
propagated in empty
space with a definite velocity c which is independent of the state of
motion of the
emitting body."

Einstien, Electrodynamics of Moving Bodies (Introduction)

This text describes Einstein's postulate that there is no preferred
inertial frame of reference.

"If at the points A and B of K there are stationary clocks which,
viewed in the stationary system, are synchronous; and if the clock at
A is moved with the velocity v along the line AB to B, then on its
arrival at B the two clocks no longer synchronize, but the clock moved
from A to B lags behind the other which has remained at B ..."

Einstien, Electrodynamics of Moving Bodies (Section 4)

The text describes the time dilation of a clock that moves from point
A to point B. If there is no preferred frame of reference then it is
just as true to say that
the clock is viewed as part of a stationary system and the points A
and B are in a moving system which moves at velocity -v. The
conclusion that time for both systems can be dilated with respect to
