More quotes by Galileo Galilei

Image
I am inclined to think that the authority of Holy Scripture is intended to convince men of those truths which are necessary for their salvation, which, being far above man's understanding, can not be made credible by any learning, or any other means than revelation by the Holy Spirit.
Galileo Galilei
Image
I am certainly interested in a tribunal in which, for having used my reason, I was deemed little less than a heretic. Who knows but men will reduce me from the profession of a philosopher to that of historian of the Inquisition!
Galileo Galilei
Image
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo Galilei
Image
Who would dare assert that we know all there is to be known?
Galileo Galilei
Image
Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.
Galileo Galilei
Image
I have never met a man so ignorant that I couldn't learn something from him.
Galileo Galilei
Image
One can understand nature only when one has learned the language and the signs in which it speaks to us but this language is mathematics and these signs are methematical figures.
Galileo Galilei
Image
They know that it is human nature to take up causes whereby a man may oppress his neighbor, no matter how unjustly. ... Hence they have had no trouble in finding men who would preach the damnability and heresy of the new doctrine from the very pulpit.
Galileo Galilei
Image
To excite in us tastes, odors, and sounds I believe that nothing is required in external bodies except shapes, numbers, and slow or rapid movements. ... if ears, tongues, and noses were removed, shapes and numbers and motions would remain, but not odors or tastes or sounds.
Galileo Galilei
Image
Some, merely to contradict what I had said, did not scruple to cast doubt upon things they had seen with their own eyes again and again.
Galileo Galilei
Image
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
Galileo Galilei
Image
They seemed to forget that the increase of known truths stimulates the investigation, establishment and growth of the arts not their dimination or destruction.
Galileo Galilei
Image
I believe that the intention of Holy Writ was to persuade men of the truths necessary to salvation such as neither science nor other means could render credible, but only the voice of the Holy Spirit.
Galileo Galilei
Image
The vain presumption of understanding everything can have no other basis than never having understood anything. For anyone who had ever experienced just once the perfect understanding of one single thing, and had truly tasted how knowledge is accomplished, would recognize that of the infinity of other truths he understands nothing.
Galileo Galilei
Image
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.
Galileo Galilei
Image
The greatest wisdom is to get to know oneself.
Galileo Galilei
Image
It is necessary for the Bible, in order to be accommodated to the understanding of every man, to speak many things which appear to differ from the absolute truth so far as the bare meaning of the words is concerned.
Galileo Galilei
Image
See now the power of truth.
Galileo Galilei
Image
But some, besides allegiance to their original error, possess I know not what fanciful interest in remaining hostile not so much toward the things in question as toward their discoverer.
Galileo Galilei
Image
Showing a greater fondness for their own opinions than for truth, they sought to deny and disprove the new things which, if they had cared to look for themselves, their own senses would have demonstrated to them.
