galileo Galilei
“All truths are easy to understand once they are discovered; the point is to discover them.”
“I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.”
“I have never met a man so ignorant that I couldn't learn something from him.”
“It is surely harmful to souls to make it a heresy to believe what is proved.”
