The Insufficiency of Nature to Explain Nature

60. The second objection is from the sufficiency of nature to explain everything we observe.
     A. What is able to be completed by fewer principles is not done by many.
     B. Supposing God does not exist, natural things can be reduced to natural principles, and intentional things are reduced to principles that are human or voluntary.
     C. Thus it is not necessary to suppose that God exists.

61. His response to the second objection appeals primarily to the fifth way: the determinacy of natural ends depends on the direction of something supernatural, i.e. God.

62. However, the second half of his reply is in a way a summary of all five ways put together: all things mobile and defectible must be reduced to some immobile and necessary first principle.
