The Warfare of Science

by Andrew Dickson White

The war on the Copernican theory, which up to that time had been carried on quietly, now flamed forth. It was declared that the doctrine was proved false by the standing still of the sun for Joshua; by the declarations that "the foundations of the earth are fixed so firm that they cannot be moved," and that the sun "runneth about from one end of heaven to the other." [40]

The Dominican father, Caccini, preached a sermon from the text, "Ye men of Galilee, why stand ye gazing up into heaven?" and this wretched pun was the first of a series of sharper weapons; for before Caccini finishes, he insists that "geometry is of the devil," and that "mathematicians should be banished as the authors of all heresies;" and, for this, the Church authorities gave Caccini promotion. [41]

Father Lorini proved that the doctrine was not only "heretical," but "atheistic," and besought the Inquisition to intervene. The Bishop of Fiesole screamed in rage against the Copernican system, and proposed to denounce Galileo to the grand-duke. The Archbishop of Pisa secretly sought to entrap Galileo and deliver him to the Inquisition at Rome. The Archbishop of Florence solemnly condemned the doctrines of Kopernik and Galileo as unscriptural.

But by far the most terrible champion who appeared against him was Bellarmin, one of the greatest of theologians, and one of the poorest of scientists. He was earnest, sincere, learned, but made the fearful mistake for the world of applying to science, direct, literal interpretation of Scripture. [42]

The weapons which men of Bellarmin's stamp used were theological. They held up before the world the dreadful consequences which must result to Christian theology were the doctrine to prevail that the heavenly bodies revolve about the sun, and not about the earth. Their most tremendous theologic engine against Galileo was the idea that his pretended discovery "vitiated the whole Christian plan of salvation." Father Lecazre declared that it "cast suspicion on the doctrine of the Incarnation." Others declared that it "upset the whole basis of theology; that, if the earth is a planet, and one among several planets, it cannot be that any such great things have been done especially for it, as the Christian doctrine teaches. If there are other planets, since God makes nothing in vain, they must be inhabited; but how can these inhabitants be descended from Adam? How can they trace back their origin to Noah's ark? How can they have been redeemed by the Saviour?" [43]

Nor was this argument confined to the theologians of the Roman Church; Melanchthon, Protestant as he was, had already used it in his attacks upon the ideas of Kopernik and his school. [44]

In addition to this prodigious engine of war, there was kept up a terrific fire of smaller artillery in the shape of texts and scriptural extracts.

But the little telescope of Galileo still swept the heavens, and the next revelation announced was the system of mountains and valleys in the moon. This was a signal for another attack. It was declared that this, coupled with the statement that the moon shines by light reflected from the sun, was a contradiction of the statement in Genesis that the moon is a "great light" like the sun. To make the matter worse, a painter, placing the moon in a religious picture in its usual position beneath the feet of the Blessed Virgin, outlined on its surface mountains and valleys; this was denounced as a sacrilege logically resulting from the astronomer's heresy.

The next struggle was aroused when the hated telescope revealed spots upon the sun, and their motion, which indicated the sun's rotation. Monsignor Elci, head of the University of Pisa, forbade the Professor of Astronomy, Castelli, to mention these spots. Father Busaeus, at the University of Innspruck, forbade the astronomer Scheiner to allow the new discovery to be known there. At the College of Douay and the University of Louvain it was expressly placed under the ban, and this became the general rule among the Catholic universities and colleges of Europe. The Spanish universities were specially intolerant of this and similar ideas, [45] and up to a recent period they were strictly forbidden in the most important university of all—that of Salamanca. In 1820 the Abbé Settele, professor at the College of Rome, having announced a work on Optics and Astronomy, the master of the sacred palace, under the authority of the old decrees against the teachings of Kopernik and Galileo, forbade the publication, and it was not until 1822 that Pope Pius VII. sanctioned a decision of the Inquisition permitting such teachings. [46]

Such are the consequences of placing the instruction of men's minds in the hands of those mainly absorbed in the work of saving men's souls. [47] Nothing could be more in accordance with the idea recently put forth by the Bishop of Montpellier, that the Church is alone fully empowered to promulgate scientific truth or direct university instruction; but science gained the victory here also. News came of observations of the solar spots, not only from Galileo in Italy, but from Fabricius in Holland. Father Scheiner then endeavors to make the usual treaty; he promulgates a pseudo-scientific theory—a statement based on a "religious science"—which only provokes derision.
