Galileo Galilei quotes

“All truths are easy to understand once they are discovered; the point is to discover them.”

“I have never met a man so ignorant that I couldn't learn something from him.”

“In the sciences, the authority of thousands of opinions is not worth as much as one tiny spark of reason in an individual man.”

“The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.”

“We cannot teach people anything; we can only help them discover it within themselves.”

“Where the senses fail us, reason must step in.”
