According to 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

According to 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."
Newton disagrees. Explain why Duhem claims what he does and indicate how Newton would criticize Duhem. How would Duhem respond? Who do you think has the correct position and why?
