Philosophy is written in this grand book-I mean the universe-which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth.

Galilei, Galileo. "Giornata Prima [First Day]." Discorsi e dimostrazioni matematiche intorno a due nuove scienze [Discourses and Mathematicals Demonstrations Relating to Two New Sciences]. Leiden: Ludovico Elzeviro, 1638.

In disputes about natural phenomena one must begin not with the authority of Scriptural passage but with sensory experience and necessary demonstrations. For the Holy Scripture and nature derive equally from the Godhead, the former as the dictation of the Holy Spirit and the latter as the most obedient executrix of God's orders.
