More quotes by 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
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 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
[Copernicus] did not ignore the Bible, but he knew very well that if his doctrine were proved, then it could not contradict the Scriptures when they were rightly understood.
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
There are those who reason well, but they are greatly outnumbered by those who reason badly.
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
Well, since paradoxes are at hand, let us see how it might be demonstrated that in a finite continuous extension it is not impossible for infinitely many voids to be found.
Galileo Galilei
Knowing thyself, that is the greatest wisdom.
Galileo Galilei
Nonetheless, it moves.
Galileo Galilei
To be humane, we must ever be ready to pronounce that wise, ingenious and modest statement 'I do not know'.
Galileo Galilei
Wine is sunlight, held together by water.
Galileo Galilei
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo Galilei
You cannot teach a person something he does not already know, you can only bring what he does know to his awareness.
Galileo Galilei
Mathematics is the language with which God has written the universe.
Galileo Galilei
And believe me, if I were again beginning my studies, I should follow the advice of Plato and start with the mathematical sciences, which proceed very cautiously and admit nothing as established until it has been rigorously demonstrated.
Galileo Galilei
Facts which at first seem improbable will, even on scant explanation, drop the cloak which has hidden them and stand forth in naked and simple beauty.
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
Showing a greater fondness for their own opinions than for truth, they sought to deny and disprove the new things which, if they had cared to look for themselves, their own senses would have demonstrated to them.
Galileo Galilei
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.
Galileo Galilei
