More quotes by Galileo Galilei
Who would dare assert that we know all there is to be known?
Galileo Galilei
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
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
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
It is surely harmful to souls to make it a heresy to believe what is proved.
Galileo Galilei
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
I do not know what to say in a case so surprising, so unlooked for and so novel.
Galileo Galilei
But, because my private lectures and domestic pupils are a great hinderance and intteruption of my studies, I wish to live entirely exempt from the former, and in great measure from the latter. ... in short, I should wish to gain my bread from my writings.
Galileo Galilei
Nonetheless, it moves.
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
They who depend upon manifest observations will philosophize better than those who persist in opinions repugnant to the senses.
Galileo Galilei
Wine is sunlight, held together by water.
Galileo Galilei
The surface of the Moon is not smooth, uniform, and precisely spherical as a great number of philosophers believe it to be, but is uneven, rough, and full of cavities and prominences, being not unlike the face of the Earth, relieved by chains of mountains and deep valleys.
Galileo Galilei
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
See now the power of truth.
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
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
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
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.
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
