the system of the universe would shortly be pronounced heretical by the highest authorities. Galileo then points out that Copernicus, the originator of these doctrines, was not only a good Catholic, but a priest highly esteemed by the Roman curia, both for his learning and piety. He had dedicated his famous work: “De Revolutionibus Orbium Cœlestium,” to Pope Paul III., and no one had felt any scruples about his doctrines, although some ill-disposed persons want to have the book pronounced heretical, without ever having read, to say nothing of studied it. As an adherent of the Copernican theory, Galileo now feels compelled, in order to justify himself, to discuss in detail these arguments from Scripture brought forward by his opponents, and he hopes to prove that he is animated by a greater zeal for true religion than his adversaries; for he by no means demands that the book should not be condemned, but that it should not be condemned without being understood or even looked at. Before proceeding to discuss these arguments, he protests that he will not only always be ready publicly to rectify the errors he may from ignorance have fallen into on religious matters in this treatise, but that it was not in the least his intention to enter into dispute with any one on such subjects; it is rather his desire, by these remarks, to incite others to deliberations useful to the Church. As to the decision about the Copernican system, we must bow to the opinions of the ecclesiastical authorities, and should it be adverse to him, let his work be torn up and burnt, for he had neither wish nor intention to promote results that were not catholic and pious.
