“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 In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler.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.”

“How did Biot arrive at the partial differential equation? [the heat conduction equation] . . . Perhaps Laplace gave Biot the equation and left him to sink or swim for a few years in trying to derive it. That would have been merely an instance of the way great mathematicians since the very beginnings of mathematical research have effortlessly maintained their superiority over ordinary mortals.”

“The ingenious method of expressing every possible number using a set of ten symbols (each symbol having a place value and an absolute value) emerged in India. The idea seems so simple nowadays that its significance and profound importance is no longer appreciated ... The importance of this invention is more readily appreciated when one considers that it was beyod the two greatest men of antiquity, Archimedes and Apollonius.”

“Probability theory is nothing more than common sense reduced to calculation. -1819”

“We ought to regard the present state of the universe as the effect of its antecedent state and as the cause of the state that is to follow. An intelligence knowing all the forces acting in nature at a given instant, as well as the momentary positions of all things in the universe, would be able to comprehend in one single formula the motions of the largest bodies as well as the lightest atoms in the world, provided that its intellect were sufficiently powerful to subject all data to analysis; to it nothing would be uncertain, the future as well as the past would be present to its eyes. The perfection that the human mind has been able to give to astronomy affords but a feeble outline of such an intelligence.”

“Your Excellency, I have no need of this hypothesis.”

“The cosmos does not require God, Laplace said to himself. But Emperors require Him. All those who seek to subjugate human beings in one form or another require Him. Science does not need God.”

“I compared what was really known about the stars with the account of creation as told in Genesis. I found that the writer of the inspired book had no knowledge of astronomy -- that he was as ignorant as a Choctaw chief -- as an Eskimo driver of dogs. Does any one imagine that the author of Genesis knew anything about the sun -- its size? that he was acquainted with Sirius, the North Star, with Capella, or that he knew anything of the clusters of stars so far away that their light, now visiting our eyes, has been traveling for two million years?If he had known these facts would he have said that Jehovah worked nearly six days to make this world, and only a part of the afternoon of the fourth day to make the sun and moon and all the stars?Yet millions of people insist that the writer of Genesis was inspired by the Creator of all worlds.Now, intelligent men, who are not frightened, whose brains have not been paralyzed by fear, know that the sacred story of creation was written by an ignorant savage. The story is inconsistent with all known facts, and every star shining in the heavens testifies that its author was an uninspired barbarian.I admit that this unknown writer was sincere, that he wrote what he believed to be true -- that he did the best he could. He did not claim to be inspired -- did not pretend that the story had been told to him by Jehovah. He simply stated the "facts" as he understood them.After I had learned a little about the stars I concluded that this writer, this "inspired" scribe, had been misled by myth and legend, and that he knew no more about creation than the average theologian of my day. In other words, that he knew absolutely nothing.And here, allow me to say that the ministers who are answering me are turning their guns in the wrong direction. These reverend gentlemen should attack the astronomers. They should malign and vilify Kepler, Copernicus, Newton, Herschel and Laplace. These men were the real destroyers of the sacred story. Then, after having disposed of them, they can wage a war against the stars, and against Jehovah himself for having furnished evidence against the truthfulness of his book.”

“Give me the positions and velocities of all the particles in the universe, and I will predict the future.”
