“You cannot teach a man anything you can only help him to find it within himself.”

“Actually, what we really need to remember about Galileo is that most of the people who use his name in argument could barely spell it, let alone tell us what actually happened to the man. His case is used over and over again because critics can't think of any other scientists who were mistreated by the Church. And in this instance they're right. There may have been some people in the scientific world who did not enjoy Church support and were even challenged by Catholicism but, sorry to disappoint, there weren't very many of them. The Church has been the handmaiden of science and scientific discovery, and those who refer to Galileo tend to forget that Louis Pasteur, the inventor of pasteurization, was a devout Catholic, as was Alexander Fleming, who gave us penicillin. Or Father Nicolaus Copernicus, who first proposed the theory of the earth revolving around the sun - this was precisely what Galileo stated, but Copernicus taught it as theory and not fact. Or Monsignor Georges Henri Joseph Édouard Lemaître, a Belgian Roman Catholic priest and professor of physics at the Catholic University of Leuven, who proposed what became known as the Big Bang theory of the origin of the Universe. In the field of acceleration, Fr. Giambattista Riccioli changed the way we understand that particular science; the father of modern Egyptology was Fr. Athanasius Kircher, and the Yugoslavian Fr. Roger Boscovich was the founder of modern atomic theory.”

“What Galileo and Newton were to the seventeenth century, Darwin was to the nineteenth.”

“Galileo, yet men turn around women!”

“BERENGER: And you consider all this natural? 

DUDARD: What could be more natural than a rhinoceros? 

BERENGER: Yes, but for a man to turn into a rhinoceros is abnormal beyond question. 

DUDARD: Well, of course, that's a matter of opinion ... 

BERENGER: It is beyond question, absolutely beyond question! 
DUDARD: You seem very sure of yourself. Who can say where the normal stops and the abnormal begins? Can you personally define these conceptions of normality and abnormality? Nobody has solved this problem yet, either medically or philosophically. You ought to know that. 

BERENGER: The problem may not be resolved philosophically -- but in practice it's simple. They may prove there's no such thing as movement ... and then you start walking ... [he starts walking up and down the room] ... and you go on walking, and you say to yourself, like Galileo, 'E pur si muove' ... 

DUDARD: You're getting things all mixed up! Don't confuse the issue. In Galileo's case it was the opposite: theoretic and scientific thought proving itself superior to mass opinion and dogmatism. 

BERENGER: [quite lost] What does all that mean? Mass opinion, dogmatism -- they're just words! I may be mixing everything up in my head but you're losing yours. You don't know what's normal and what isn't any more. I couldn't care less about Galileo ... I don't give a damn about Galileo. 

DUDARD: You brought him up in the first place and raised the whole question, saying that practice always had the last word. Maybe it does, but only when it proceeds from theory! The history of thought and science proves that. BERENGER: [more and more furious] It doesn't prove anything of the sort! It's all gibberish, utter lunacy! 

DUDARD: There again we need to define exactly what we mean by lunacy ... 

BERENGER: Lunacy is lunacy and that's all there is to it! Everybody knows what lunacy is. And what about the rhinoceroses -- are they practice or are they theory?”

“We're better than Galileo. Because he's dead.”

“After a duration of a thousand years, the power of astrology broke down when, with Copernicus, Kepler, and Galileo, the progress of astronomy overthrew the false hypothesis upon which the entire structure rested, namely the geocentric system of the universe. The fact that the earth revolves in space intervened to upset the complicated play of planetary influences, and the silent stars, related to the unfathomable depths of the sky, no longer made their prophetic voices audible to mankind. Celestial mechanics and spectrum analysis finally robbed them of their mysterious prestige.”

“If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of inspiration. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.”

“But it does move.”

“You cannot teach a man anything you can only help him to find it within himself.”

“Surely it is a great thing to increase the numerous host of fixed stars previously visible to the unaided vision, adding countless more which have never before been seen, exposing these plainly to the eye in numbers ten times exceeding the old and familiar stars.”
