More quotes by Galileo Galilei
My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?
Galileo Galilei
There are those who reason well, but they are greatly outnumbered by those who reason badly.
Galileo Galilei
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
Galileo Galilei
Nothing physical which sense-experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called in question (much less condemned) upon the testimony of biblical passages...
Galileo Galilei
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
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
Nonetheless, it moves.
Galileo Galilei
I would beg the wise and learned fathers [of the church] to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration.
Galileo Galilei
Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.
Galileo Galilei
By denying scientific principles, one may maintain any paradox.
Galileo Galilei
In time you may discover everything that can be discovered, and still your progress will only be progress away from humanity. The distance between you and them can one day become so great that your joyous cry over some new gain could be answered by an universal shriek of horror.
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
With regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them.
Galileo Galilei
You can't teach anybody anything, only make them realize the answers are already inside them.
Galileo Galilei
See now the power of truth.
Galileo Galilei
Philosophy is written in that great book which ever lies before our eyes — I mean the universe — but we cannot understand it if we do not first learn the language and grasp the symbols, in which it is written.
Galileo Galilei
The Bible shows the way to go to heaven, not the way the heavens go.
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.
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
I have never met a man so ignorant that I couldn't learn something from him.
Galileo Galilei
