Philosophy is written in this grand book - I mean universe - which stands continuously open to our gaze, but which cannot be understood unless one first learns to comprehend the language in which it is written. It is written in the language of mathematics, and its characters are triangles, circles and other geometric figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth.Galileo (1623)
Good quote, showing how Galileo undertood the universe cannot be comprehended apart from intelligent design, which is to be expected since the ultimate source of Truth has told us as much in the biblical texts.
