 The third proof of this universal law of nature is based upon its agreement with the final purpose of creation. From the assumption of a creator of the world who acts with wisest of intentions, it follows that promotion of the perfection of the creation must be God’s will. To be sure, might never makes right and Mendelssohn accordingly stresses that law is a consequence not of divine power but of the right of a divine will. Nonetheless, from (i) the fact that God can only want what is best and (ii) the fact that “a right is nothing other than a moral capacity to do what conforms to the rule of perfection,” it follows that God possesses the right to prescribe to his creation laws that are necessarily rules of its perfection. This third proof arguably represents a further departure from Wolff who rejects the equivalence of the natural law with a divine command. For Wolff, only someone lacking reason has need of motivations other than natural obligatoriness (Klemme 295f).
