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
I truly believe the book of philosophy to be that which stands perpetually open before our eyes, though since it is written in characters different from those of our alphabet it cannot be read by everyone.
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

Knowing thyself, that is the greatest wisdom.

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.

See now the power of truth.

By denying scientific principles, one may maintain any paradox.

It is surely harmful to souls to make it a heresy to believe what is proved.

Measure what can be measured, and make measureable what cannot be measured.
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.

The Bible shows the way to go to heaven, not the way the heavens go.
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
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.

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?

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.

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...
