I find "THE MOON IS IN FACT A PERFECT SPHERE" a declaration of exquisite

Famous in the history of science is the argument _ad ignorantiam_ given
in criticism of Galileo, when he showed leading astronomers of his time
the mountains and valleys on the moon that could be seen through his
telescope. Some scholars of that age, absolutely convinced that the
moon was a perfect sphere, as theology and Aristotelian science had
long taught, argued against Galileo that, although we see what appear
to be mountains and valleys, THE MOON IS IN FACT A PERFECT SPHERE,
because all its apparent irregularities are filled in by an invisible
crystalline substance. And this hypothesis, which saves the perfection
of the heavenly bodies, Galileo could not prove false!
