“So, when they are all included in one, they are hidden and useless, as in a chest, and never appear save in their natural confusion. Nature has established them all without including one in the other.
21 Nature has made all her truths independent of one another. Our art makes one dependent on the other.
But this is not natural. Each keeps its own place.
22 Let no one say that I have said nothing new; the arrangement of the subject is new. When we play tennis, we both play with the same ball, but one of us places it better.”
