Nicolaus Copernicus — "The Universe has been wrought for us by a supremely good and orderly Creator."

"For the mind, which is created in the image of God, is capable of understanding the divine order of the universe."

"It is the duty of a good astronomer to seek for truth in all things, and to follow it wherever it may lead."

"For it is clear that the earth performs a double motion: one about its axis, and another about the sun."

"To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge."

"For if the earth should move from west to east, the fixed stars would appear to move from east to west."
