They attacked the astronomers as though they were criminals—the geologists as though they were assassins. They regarded physicians as the enemies of God—as men who were trying to defeat the decrees of Providence. The biologists, the anthropologists, the archaeologists, the readers of ancient inscriptions, the delvers in buried cities, were all hated by the theologians. They were afraid that these men might find something inconsistent with the Bible.

Galileo’s own description of his ecclesiastical travails is contained in a letter he wrote in the year 1615 to the Grand Duchess Christina: Some years ago as Your Serene Highness well knows, I discovered in the heavens many things that had not been seen before our own age. The novelty of these things, as well as some consequences which followed from them in contradiction to the physical notions commonly held among academic philosophers, stirred up against me no small number of professors [many of them ecclesiastics] — as if I had placed these things in the sky with my own hands in order to upset Nature and overturn the sciences. They seemed to forget that the increase of known truths stimulates the investigation, establishment, and growth of the arts.

The Reformation was a popular uprising, and for a century and a half drenched Europe in blood. The beginnings of the Scientific movement were confined to a minority among the intellectual elite.… [T]he worst that happened to men of science was that Galileo suffered an honorable detention and a mild reproof, before dying peacefully in his bed. The way in which the persecution of Galileo has been remembered is a tribute to the quiet commencement of the most intimate change in outlook which the human race had yet encountered. Since a babe was born in a manger, it may be doubted whether so great a thing has happened with so little stir.

Some ancients speculated that the stars were small holes in a black sphere through which distant light shone through. ...Giordano Bruno suggested that they were... like our Sun, just much farther away, perhaps with their own planets and civilizations... the Catholic Church had him burned at the stake in 1600.

If we are to discuss the idea of God and be restricted to rational arguments, then it is probably useful to know what we are talking about when we say “God.” This turns out not to be easy. The Romans called the Christians atheists. Why? Well, the Christians had a god of sorts, but it wasn’t a real god. They didn’t believe in the divinity of apotheosized emperors or Olympian gods. They had a peculiar, different kind of god. So it was very easy to call people who believed in a different kind of god atheists. And that general sense that an atheist is anybody who doesn’t believe exactly as I do prevails in our own time.

Perhaps I am a crank, Martin. There are many who hate me. There are plots against me—oh, you t'ink I imagine it, but you shall see! I make many mistakes. But one thing I keep always pure: the religion of a scientist. To be a scientist—it is not just a different job, so that a man should choose between being a scientist and being an explorer or a bond-salesman or a physician or a king or a farmer. It is a tangle of ver-y obscure emotions, like mysticism, or wanting to write poetry; it makes its victim all different from the good normal man. The normal man, he does not care much what he does except that he should eat and sleep and make love. But the scientist is intensely religious—he is so religious that he will not accept quarter-truths, because they are an insult to his faith. He wants that everything should be subject to inexorable laws. He is equal opposed to the capitalists who t'ink their silly money-grabbing is a system, and to liberals who t'ink man is not a fighting animal; he takes both the American booster and the European aristocrat, and he ignores all their blithering. Ignores it! All of it! He hates the preachers who talk their fables, but he iss not too kindly to the anthropologists and historians who can only make guesses, yet they have the nerf to call themselves scientists! Oh, yes, he is a man that all nice good-natured people should naturally hate! ~ Gottlieb, Ch. 26

In the history of science, ever since the famous trial of Galileo, it has repeatedly been claimed that scientific truth cannot be reconciled with the religious interpretation of the world. Although I an now convinced that scientific truth is unassailable in its own field, I have never found it possible to dismiss the content of religious thinking as simply part of an outmoded phase in the consciousness of mankind, a part we shall have to give up from now on, Thus in the course of my life I have repeatedly been compelled to ponder on the relationship of these two regions of though, for I have never been able to doubt the reality of that to which they point.

Although not a single leader of the Third Reich — not even Hitler himself — was ever excommunicated, Galileo was not absolved of heresy until 1992.

On June 22nd, [1633,] in the morning, in the great hall of the Convent of Santa Maria Sopra Minerva, Galileo was found guilty of holding a false doctrine. He went down on his knees and both abjured and condemned his own errors. He swore never to argue such doctrines again. It was thus definitely confirmed that the sun did rotate around the earth...Santa Maria Sopra Minerva. Saint Mary Over Minerva. Power over wisdom.

Expressions of sharp and even violent criticism of religion and the church have been welcomed, for they usually imply sincerity of thought. If caustic criticism of religious institutions and practices is irreligious, then Amos, Isaiah, and Jesus were very irreligious men. In fact, that is exactly what many of their contemporaries took them to be.

The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image ; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.

"Maria Mitchell, ... - having long considered Galileo "not a mere observer and discoverer, but a philosopher," she sees not only the tragedy of his truth but also its triumph: “I knew of no sadder picture in the history of science than that of the old man, Galileo, worn by a long life of scientific research, weak and feeble, trembling before that tribunal whose frown was torture, and declaring that to be false which he knew to be true. And I know of no picture in the history of religion more weakly pitiable than that of the Holy Church trembling before Galileo, and denouncing him because he found in the Book of Nature truths not stated in their own Book of God-forgetting that the Book of Nature is also the Book of God. It seems to be difficult for anyone to take in the idea that two truths cannot conflict."

Most historians merely mention that Bruno was charged with the heresy of teaching Copernican astronomy, but Frances Yates, a historian who specialized in the occult aspects of the scientific revolution, points out that Bruno was charged with 18 heresies and crimes, including the practice of sorcery and organizing secret societies to oppose the Vatican. Yates thinks Bruno may have had a role in the invention of either Rosicrucianism or Freemasonry or both. Bruno's teachings combined the new science of his time with traditional Cabalistic mysticism. He believed in a universe of infinite space with infinite planets, and in a kind of dualistic pantheism, in which the divine is incarnate in every part but always in conflicting forms that both oppose and support each other. Whatever his link with occult secret societies, he influenced Hegel, Marx, theosophy, James Joyce, Timothy Leary, Discordianism, and Dr. Wilhelm Reich.
