“For, the sun is not inappropriately called by some people the lantern of the universe, its mind by others, and its ruler by still others.”

“But if one believed that the earth revolved, he would certainly be of the opinion that this movement was natural and not arbitrary.”

“I am not so enamored of my own opinions that I disregard what others may think of them.”

“Thus indeed, as though seated on a royal throne, the sun governs the family of planets revolving around it.”

“For my part I believe that gravity is nothing but a certain natural desire, which the divine providence of the Creator of all things has implanted in parts, to gather as a unity and a whole by combining in the form of a globe.”
