Copernicus not only moved the Earth but also set in motion the minds of men

In 1473 Copernicus was born. In 1543 his great work appeared. In 1616 the system of Copernicus was condemned by the pope, by the infallible Catholic Church, and the church was about as near right upon that subject as upon any other. The system of Copernicus was denounced. And how long do you suppose the church fought that? Let me tell you. It was revoked by Pius VII. in the year of grace 1821. For two hundred and seventy-eight years after the death of Copernicus the church insisted that his system was false, and that the old Bible astronomy was true.

In the history of thought... objectivity was sometimes on the side of one man against the rest of humankind. For example, in Copernicus' time the objective astronomical reality existed only for him, while hundreds of millions of people were mistaken in this regard... Copernicus alone embraced the accumulated astronomical experience up to that time in its entirety and was able to organize it harmoniously with the methods which corresponded to the level achieved by the collective efforts of humankind; other people possessed only parts and fragments of this experience, so that it remained unorganized in all its fullness.

Copernicus published his manuscript in 1543 just in time for the council of Trent. So you're a church father and what this new system of Copernicus is saying is this: The Earth moves, although the Bible says it doesn't. It's no longer at the center of God's universe, although the Bible says it is. It's a planet, so heaven and Earth are no longer separate. And Aristotle was wrong, although church authority depends on his being right. You're a church father and you pick up this subversive, heretical, revolutionary piece of lunacy and you start foaming at the mouth, right? Wrong. When the council finally got around to reading Copernicus they were delighted. His new system had made calendar reform more precise. And the business of it turning every basic belief about the universe on its head? A mere fairytale since from the church's viewpoint he was talking nonsense. Astronomy drew lines and circles in the sky but they weren't really there, they're a mathematical convenience for measuring or teaching astronomy. While the Copernicus system might well have been brilliant mathematics, no one thought for a minute that he was actually suggesting the earth was whizzing around the sun. That kind of talk would blow holes in everything.

Copernicus and Darwin undermined man’s image of himself as the ‘measure of all things’. Newton provided him with a new hope … that of ‘man as the measurer of all things’. Thus the possibility was revealed to man, who had been disinherited from being at the center of the universe, that he might be able know how to work himself back there. Science, at the same time it destroyed his ontological security, gave him the tools for reapproaching Eden.

In effect what Luther said in 1517 was that we may appeal to a demonstrable work of God, the Bible, to override any established authority. The Scientific Revolution begins when Nicolaus Copernicus implied the bolder proposition that there is another work of God to which we may appeal even beyond this: the great work of nature. No absolute statement is allowed to be out of reach of the test, that its consequence must conform to the facts of nature. The habit of testing and correcting the concept by its consequences in experience has been the spring within the movement of our civilization ever since. In science and in art and in self-knowledge we explore and move constantly by turning to the world of sense to ask, Is this so? This is the habit of truth, always minute yet always urgent, which for four hundred years has entered every action of ours; and has made our society and the value it sets on man.

Modern science was born in the period beginning with Copernicus's work De Revolutionibus Orbium Coelestium (1543) and ending with Newton's Philosophia Naturalis Philosophiae Mathematica.

Copernicus' picture did more than picture the solar system correctly: it painted a new world picture.

As Voltaire once remarked, "It is the privilege of the real genius, especially one who opens up a new path, to make great mistakes with impunity." The Copernican revolution brought about by Kant was, I think, the most important single turning point in the history of philosophy. For that reason there has been, ever since, a watershed in understanding between those who have taken his work on board and those who have not. For a good many of the problems he uncovered, the solutions he put forward have not stood the test of time, but his uncovering of the problems remains the most illuminating thing a philosopher has ever done. Because of the fundamental character of these problems, and because Kant did not solve them, confronting them has been the most important challenge to philosophy ever since.

That goes a step too far, I think. Leonardo did not invent the scientific method, nor did Aristotle or Alhazen or Galileo or any Bacon. But his uncanny abilities to engage in the dialogue between experience and theory made him a prime example of how acute observations, fanatic curiosity, experimental testing, a willingness to question dogma, and the ability to discern patterns across disciplines can lead to great leaps in human understanding.

But among all the discoveries and corrections probably none has resulted in a deeper influence on the human spirit than the doctrine of Copernicus…. Possibly mankind has never been demanded to do more, for considering all that went up in smoke as a result of realizing this change: a second Paradise, a world of innocence, poetry and piety: the witness of the senses, the conviction of a poetical and religious faith. No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown indeed not even dreamed of.

One man I know, and one only, who can be praised for his achievements in this science. Of discourses and battles of words he takes no heed: he follows the works of wisdom, and in these finds rest. What others strive to see dimly and blindly, like bats in twilight, he gazes at in the full light of day, because he is a master of experiment. Through experiment he gains knowledge of natural things, medical, chemical, indeed of everything in the heavens or earth. He is ashamed that things should be known to laymen, old women, soldiers, ploughmen, of which he is ignorant. Therefore he has looked closely into the doings of those who work in metals and minerals of all kinds; he knows everything relating to the art of war, the making of weapons, and the chase; he has looked closely into agriculture, mensuration, and farming work; he has even taken note of the remedies, lot casting, and charms used by old women and by wizards and magicians, and of the deceptions and devices of conjurors, so that nothing which deserves inquiry should escape him, and that he may be able to expose the falsehoods of magicians. If philosophy is to be carried to its perfection and is to be handled with utility and certainty, his aid is indispensable. As for reward, he neither receives nor seeks it. If he frequented kings and princes, he would easily find those who would bestow on him honours and wealth. Or, if in Paris he would display the results of his researches, the whole world would follow him. But since either of these courses would hinder him from pursuing the great experiments in which he delights, he puts honour and wealth aside, knowing well that his wisdom would secure him wealth whenever he chose. For the last three years he has been working at the production of a mirror that shall produce combustion at a fixed distance; a problem which the Latins have neither solved nor attempted, though books have been written upon the subject.

[T]radition links us with the revolutionary science of the Renaissance... we can distinguish... four major periods of advance. [C]entred in Italy... the renewal of mechanics, anatomy, and astronomy with Leonardo, Vesalius, and Copernicus, destroying the authority of the Ancients in their central doctrines of man and the world. [S]preading to the Low Countries, France, and Britain, beginning with Bacon, Galileo, and Descartes, and ending in Newton, hammered out a new mathematical mechanical model of the world. [C]entred in industrial Britain and revolutionary Paris, opened... areas of experience... as... electricity... It was then that science could help... with power, machinery, and chemicals, to transform production and transport. [T]he scientific revolution of our own time. ...[T]he beginning of a world science, transforming old and creating new industries, permeating every aspect of human life. ...[N]ow... we find science directly involved in the violent and terrible drama of wars and social revolution.

Copernicus stuck very closely to the facts, but in Kepler I invented freely, and it's a much better book because of that.
