More quotes by Galileo Galilei

Image
When the moon is ninety degrees away from the sun it sees but half the earth illuminated (the western half). For the other (the eastern half) is enveloped in night. Hence the moon itself is illuminated less brightly from the earth, and as a result its secondary light appears fainter to us.

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
By denying scientific principles, one may maintain any paradox.
Galileo Galilei
Image
I have never met a man so ignorant that I couldn't learn something from him.
Galileo Galilei

There are those who reason well, but they are greatly outnumbered by those who reason badly.
Galileo Galilei
Image
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
Image
I do not know what to say in a case so surprising, so unlooked for and so novel.
Galileo Galilei
Image
Philosophy itself cannot but benefit from our disputes, for if our conceptions prove true, new achievements will be made if false, their refutation will further confirm the original doctrines.

Image
I, Galileo, son of the late Vicenzo Galilei, swear that I never said that the prime numbers are useless. What I said was that you cannot count lunar craters by counting 2, 3, 5, 7.

Image
Knowing thyself, that is the greatest wisdom.
Galileo Galilei
Image
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo Galilei
Image
The number of people that can reason well is much smaller than those that can reason badly. If reasoning were like hauling rocks, then several reasoners might be better than one. But reasoning isn't like hauling rocks, it's like, it's like racing, where a single, galloping Barbary steed easily outruns a hundred wagon-pulling horses.
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.

To be humane, we must ever be ready to pronounce that wise, ingenious and modest statement 'I do not know'.
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!

Image
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.

The Universe is a grand book which cannot be read until one first learns to comprehend the language and become familiar with the characters in which it is composed. It is written in the language of mathematics.
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
All truths are easy to understand once they are discovered the point is to discover them.

Surely, God could have caused birds to fly with their bones made of solid gold, with their veins full of quicksilver, with their flesh heavier than lead, and with their wings exceedingly small. He did not, and that ought to show something. It is only in order to shield your ignorance that you put the Lord at every turn to the refuge of a miracle.
