"In my opinion, therefore, sight is the basis of our greatest benefits as we could not have said anything about the universe if we had never seen the sun, the stars, and the sky. Moreover, it is the perception of day and night, of solstices and equinoxes, of months and years that follow one another, which has led to the invention of numbers and has given us the notion of time and the nature of reality, from which we have drawn every philosophy, a heavenly gift greater than which man has never had nor will ever have."
