Galileo Galilei quotes about
Nothing physical which sense-experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called into question (much less condemned) upon the testimony of biblical passages.
To command the professors of astronomy to confute their own observations is to enjoin an impossibility, for it is to command them not to see what they do see, and not to understand what they do understand, and to find what they do not discover.
Mathematics is the key and door to the sciences.
We cannot teach people anything; we can only help them discover it within themselves.
Mathematics is the language with which God has written the universe.
We see only the simple motion of descent, since that other circular one common to the Earth, the tower, and ourselves remains imperceptible. There remains perceptible to us only that of the stone, which is not shared by us; and, because of this, sense shows it as by a straight line, always parallel to the tower, which is built upright and perpendicular upon the terrestrial surface.
I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forego their use.
All truths are easy to understand once they are discovered; the point is to discover them.
The greatest wisdom is to get to know oneself.
Among the great men who have philosophized about [the action of the tides], the one who surprised me most is Kepler. He was a person of independent genius, [but he] became interested in the action of the moon on the water, and in other occult phenomena, and similar childishness.
By denying scientific principles, one may maintain any paradox.
Science proceeds more by what it has learned to ignore than what it takes into account.
Wine is sunlight, held together by water.
If you could see the earth illuminated when you were in a place as dark as night, it would look to you more splendid than the moon.
