We do not see this sublime repose in the attitude of Galileo,—this falling back on his own conscious greatness, willing to let things take their natural course; but rather, on the other hand, an impatience under contradiction, a vehement scorn of adversaries, and an intellectual arrogance that gave offence, and impeded his career, and injured his fame. No matter how great a man may be, his intellectual pride is always offensive; and when united with sarcasm and mockery it will make bitter enemies, who will pull him down.
Galileo, on his transfer to Padua, began to teach the doctrines of Copernicus,—a much greater genius than he, and yet one who provoked no enmities, although he made the greatest revolution in astronomical knowledge that any man ever made, since he was in no haste to reveal his discoveries, and stated them in a calm and inoffensive way. I doubt if new discoverers in science meet with serious opposition when men themselves are not attacked, and they are made to appeal to calm intelligence, and war is not made on those Scripture texts which seem to controvert them. Even theologians receive science when science is not made to undermine theological declarations, and when the divorce of science from revelation, reason from faith, as two distinct realms, is vigorously insisted upon. Pascal incurred no hostilities for his scientific investigations, nor Newton, nor Laplace. It is only when scientific men sneer at the Bible because its declarations cannot always be harmonized with science, that the hostilities of theologians are provoked. And it is only when theologians deny scientific discoveries that seem to conflict with texts of Scripture, that opposition arises among scientific men. It would seem that the doctrines of Copernicus were offensive to churchmen on this narrow ground. It was hard to believe that the earth revolved around the sun, when the opinions of the learned for two thousand years were unanimous that the sun revolved around the earth. Had both theologian and scientist let the Bible alone, there would not have been a bitter war between them. But scientists were accused by theologians of undermining the Bible; and the theologians were accused of stupid obstinacy, and were mercilessly exposed to ridicule.
That was the great error of Galileo. He made fun and sport of the theologians, as Samson did of the Philistines; and the Philistines of Galileo’s day cut off his locks and put out his eyes when the Pope put him into their power,—those Dominican inquisitors who made a crusade against human thought. If Galileo had shown more tact and less arrogance, possibly those Dominican doctors might have joined the chorus of universal praise; for they were learned men, although devoted to a bad system, and incapable of seeing truth when their old authorities were ridiculed and set at nought. Galileo did not deny the Scriptures, but his spirit was mocking; and he seemed to prejudiced people to undermine the truths which were felt to be vital for the preservation of faith in the world. And as some scientific truths seemed to be adverse to Scripture declarations, the transition was easy to a denial of the inspiration which was claimed by nearly all Christian sects, both Catholic and Protestant.
