Galileo Quotes

Galileo - the father of modern physics - indeed of modern science.

I have been judged vehemently suspect of heresy, that is, of having held and believed that the sun in the centre of the universe and immoveable, and that the earth is not at the center of same, and that it does move. Wishing however, to remove from the minds of your Eminences and all faithful Christians this vehement suspicion reasonably conceived against me, I abjure with a sincere heart and unfeigned faith, I curse and detest the said errors and heresies, and generally all and every error, heresy, and sect contrary to the Holy Catholic Church. (Quoted in Shea and Artigas 194)

Galileo had already made a significant beginning toward a knowledge of the law of motion. He discovered the law of inertia and the law of bodies falling freely in the gravitational field of the earth.

Galileo was no idiot. Only an idiot could believe that science requires martyrdom - that may be necessary in religion, but in time a scientific result will establish itself.

Those who believe that there are men on the other side of the earth fail to observe that even if the world is held to be global or rounded in shape, or if some process of reasoning should prove this to be the case, it would still not necessarily follow that the land on the opposite side is not covered by masses of water.

A Galileo could no more be elected president of the United States than he could be elected Pope of Rome. Both high posts are reserved for men favored by God with an extraordinary genius for swathing the bitter facts of life in bandages of self-illusion.

Galileo, perhaps more than any other single person, was responsible for the birth of modern science.

The Church has opposed every innovation and discovery from the day of Galileo down to our own time, when the use of anesthetics in childbirth was regarded as a sin because it avoided the biblical curse pronounced against Eve.

It is astonishing to realize that until Galileo performed his experiments on the acceleration of gravity in the early seventeenth century, nobody questioned Aristotle's falling balls. Nobody said, Show Me!

One of the things that always fascinated me about the Renaissance was that it was a time both of great scientific discovery and also of superstition and belief in magic. And so it was a period in which Galileo invented the telescope, but also a time when hundreds were burned at the stake because people thought they were witches.

After Galileo was convicted (for heresy by the Spanish Inquisition) for his theory that the Earth revolved around the sun, ... he replied, 'Still, the Earth is moving.'

Throughout history, humankind has been resistant to change and to the acceptance of new ideas... When Galileo discovered the moons of Jupiter, the astronomers of that time refused to accept or even to look at these satellites because the existence of these moons conflicted with their accepted beliefs. So it is now with psychiatrists and other therapists, who refuse to examine and evaluate the considerable evidence being gathered about survival after bodily death and about past life memories. Their eyes are tightly shut.

Imagine how they would have mocked you if you proclaimed, 'Not only is the world a sphere, but there is an invisible, mystical force that holds everything to its surface'!

The Egyptians saw the sun and called him Ra, the Sun God. He rode across the sky in his chariot until it was time to sleep. Copernicus and Galileo proved otherwise, and poor Ra lost his divinity.

Oh, my dear Kepler, how I wish that we could have one hearty laugh together. Here, at Padua, is the principal professor of philosophy, whom I have repeatedly and urgently requested to look at the moon and planets through my glass, [telescope] which he pertinaciously refuses to do. Why are you not here? what shouts of laughter we should have at this glorious folly! and to hear the professor of philosophy at Pisa laboring before the grand duke with logical arguments, as if with magical incantations, to charm the new planets out of the sky.

I have been enjoined by this Holy Office altogether to abandon the false opinion which maintains that the sun is the center and immovable, and forbidden to hold, defend, or teach the said false doctrine in any manner, and after it hath been signified to me that the said doctrine is repugnant with the Holy Scripture, I have written and printed a book, in which I treat of the same doctrine now condemned, and adduce reasons with great force in support of the same, without giving any solution, and therefore have been judged grievously suspected of heresy; that is to say, that I held and believed that the sun is the center of the universe and is immovable, and that the earth is not the center and is movable; willing, therefore, to remove from the minds of your Eminences, and of every Catholic Christian, this vehement suspicion rightfully entertained toward me, with a sincere heart and unfeigned faith, I abjure, curse, and detest the said errors and heresies, and generally every other error and sect contrary to Holy Church; and I swear that I will never more in future say or assert anything verbally, or in writing, which may give rise to a similar suspicion of me; but if I shall know any heretic, or anyone suspected of heresy, that I will denounce him to this Holy Office, or to the Inquisitor or Ordinary of the place where I may be; I swear, moreover, and promise, that I will fulfill and observe fully, all the penances which have been or shall be laid on me by this Holy Office.

A man does not attain the status of Galileo merely because he is persecuted; he must also be right.

I don't think I'm as revolutionary as Galileo, but I don't think I'm not as revolutionary as Galileo.

Galileo probably would have escaped persecution if his discoveries could have been disproved.

While most of those who hold that the whole heaven is finite say that the earth lies at the center, the philosophers of Italy, the so-called Pythagoreans, assert the contrary. They say that in the middle there is fire, and that the earth is one of the stars, and by its circular motion round the center produces night and day

It took the Church until 1832 to remove Galileo 's work from its list of books which Catholics were forbidden to read at the risk of dire punishment of their immortal souls.

For the pre-Darwinian age had come to be regarded as a Dark Age in which men still believed that the book of Genesis was a standard scientific treatise, and that the only additions to it were Galileo'a demonstration of Leonardo da Vinci's simple remark that the earth is a moon of the sun, Sir Humphrey Davy's invention of the safety lamp, the discovery of electricity, the application of steam to industrial purposes, and the penny post.

I think it's time we recognized the Dark Ages are over. Galileo and Copernicus have been proven right. The world is in fact round; the Earth does revolve around the sun. I believe God gave us intellect to differentiate between imprisoning dogma and sound ethical science, which is what we must do here today.

The earth is not in the centre of the Sun's orbit nor at the centre of the universe

Between their rise in the thirteenth century and their sudden fall in the seventeenth, when the line abruptly ended, the Medicis produced three popes, two queens, and many Florentine rulers, and they supported the work of Galileo, Michelangelo, Leonardo, and Botticelli - a veritable parade of geniuses.
