More quotes by Galileo Galilei
Nature is written in mathematical language.
Galileo Galilei
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
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo Galilei
By denying scientific principles, one may maintain any paradox.
Galileo Galilei
Science proceeds more by what it has learned to ignore than what it takes into account.
Galileo Galilei
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
Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.
Galileo Galilei
If experiments are performed thousands of times at all seasons and in every place without once producing the effects mentioned by your philosophers, poets, and historians, this will mean nothing and we must believe their words rather than our own eyes?
Galileo Galilei
Nonetheless, it moves.
Galileo Galilei
It is a beautiful and delightful sight to behold the body of the Moon.
Galileo Galilei
Long experience has taught me this about the status of mankind with regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them, while on the other hand to know and understand a multitude of things renders men cautious in passing judgment upon anything new.
Galileo Galilei
It is surely harmful to souls to make it a heresy to believe what is proved.
Galileo Galilei
Who would dare assert that we know all there is to be known?
Galileo Galilei
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.
Galileo Galilei
I abjure with a sincere heart and unfeigned faith, I curse and detest the said errors and heresies, and generally all and every error and sect contrary to the Holy Catholic Church.
Galileo Galilei
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
It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand.
Galileo Galilei
To be humane, we must ever be ready to pronounce that wise, ingenious and modest statement 'I do not know'.
Galileo Galilei
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
The laws of Nature are written in the language of mathematics...the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word.
