Theories of the Medicean Planets Deduced from Physical Causes

if my hope has been frustrated, such that I have not reached the designated goal, I know that great things are to be desired rather than achieved by human weakness original: "humana imbecillitate." Borelli uses this traditional modest phrasing to acknowledge the limitations of human intellect when compared to the vastness of the universe..
And I do not doubt that you, best and most renowned Prince, will look with favor upon my effort, whatever it may be. You know best how deeply truth itself lies hidden, which Plato granted only to the Gods, while allowing us merely to handle shadows This refers to Plato's "Allegory of the Cave," where humans only see the shadows of true forms. Borelli suggests his scientific discoveries are these "shadows" of a higher divine truth.. But whatever those shadows may be, I do not despair that a most merciful and kind Prince will deign to receive this as a lasting monument of my gratitude and devotion. For you, I wish and vow eternal glory and happiness. Florence, October 20, 1665.
