Clifford Will explains Divine Albert's attitude:

Clifford Will: "While the great physicists of the day, such as
Lorentz, Poincare and others were struggling to bring all these facts
together by proposing concepts such as "internal time", or postulating
and then rejecting "aether drift", Einstein's attitude seems to have
been similar to that expressed in the American idiom: "if it walks
like a duck and quacks like a duck, it's a duck". If light's speed
seems to be constant, then perhaps it really is a constant, no matter
who measures it."
