13. That is, “In this limitless universe, He has created countless numbers of things, but none of them is ugly and ill-shaped: everything has its own special beauty: everything is proportionate and symmetrical in its own way. Whatever He has made for a particular purpose, He has given it the most appropriate form and invested it with the most suitable qualities for it. No better and more appropriate structure could be conceived, for example, for the eye and the ear which have been made for seeing and hearing. The air has precisely the same qualities which it should have for the purpose for which it has been made, and the water precisely the same qualities for the purpose for which it has been made. No one can point out any defect or flaw in the design of anything made by God; nor can anyone offer an alteration or modification in it.”
