Galileo Galilei Quotes

All truths are easy to understand once they are discovered; the point is to discover them.
Galileo
Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not.
Galileo
I would say here something that was heard from an ecclesiastic of the most eminent degree; "That the intention of the Holy Ghost is to teach us how one goes to heaven, not how the heaven goes."
Variant: The Bible shows the way to go to heaven, not the way the heavens go.
Galileo (Letter to Grand Duchess Christine, 1615)
Mathematics is the language with which God has written the universe.
Galileo
If I were again beginning my studies, I would follow the advice of Plato and start with mathematics.
Galileo
By denying scientific principles, one may maintain any paradox.

Galileo (Letter to Grand Duchess Christine, 1615)
Where the senses fail us, reason must step in.
Galileo
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

Galileo
And yet it does move.
Galileo (Famous words according to legend - Referring to the Earth's movement)
I have never met a man so ignorant that I couldn't learn something from him.
Galileo
And who can doubt that it will lead to the worst disorders when minds created free by God are compelled to submit slavishly to an outside will? When we are told to deny our senses and subject them to the whim of others? When people devoid of whatsoever competence are made judgesover experts and are granted authority to treat them as they please? These are the novelties which are apt to bring about the ruin of commonwealths and the subversion of the state.
Galileo
The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.
Galileo
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations
Galileo
Count what is countable, measure what is measurable, and what is not measurable, make measurable.
Galileo
I've loved the stars too fondly to be fearful of the night.
Galileo
It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.
Galileo
Philosophy is written in this grand book—I mean the universe—
which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it.
Galileo (Il Saggiatore - Rejecting the qualitative sciecne of Aristotle, 1623)
You cannot teach a man anything; you can only help him discover it in himself.
Galileo
