The book by Nicholas Copernicus of Torun was printed not long ago and published in recent days. In it he tries to revive the teaching of certain Pythagoreans concerning the Earth’s motion, a teaching which had died out in times long past.
Nobody accepts it now except Copernicus. [Copernicus is] an expert in mathematics and astronomy, but he is very deficient in physics. … Hence, since Copernicus does not understand physics … it is not surprising if he is mistaken in this opinion and accepts the false as true, through ignorance of those sciences … it is stupid to contradict a belief accepted by everyone over a very long time for extremely strong reasons, unless the naysayer uses more powerful and incontrovertible proofs, and completely rebuts the opposed reasoning.
Copernicus does not do this at all. For he does not undermine the proofs, establishing necessary conclusions, advanced by Aristotle the philosopher and Ptolemy the astronomer.Aristotle absolutely destroyed the arguments of the Pythagoreans. Yet this is not adduced by Copernicus in his ignorance of it.
Almost all the hypotheses of this author Copernicus contain something false, and very many absurdities follow from them. … For by a foolish effort [Copernicus] tries to revive the contrived Pythagorean belief, long since deservedly buried, since it explicitly contradicts human reason.
