Man is a marvelous curiosity. . . he thinks he is the Creator's pet. . . he even believes the Creator loves him; has passion for him; sits up nights to admire him; yes and watch over him and keep him out of trouble. He prays to him and thinks he listens. Isn't it a quaint idea.
Pierre Duhem
Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.
