Necessarily opposable wills undermine the claim that two distinct beings could have necessarily harmonious wills

Another possible problem concerns the truth of 10. Thus, Thomas Morris has objected that one could be unconditionally committed to each of two distinct beings provided that their wills were necessarily harmonious. For if their wills were necessarily harmonious, they could not require of us conflicting acts. This objection should be discounted, however, because the wills of distinct persons are necessarily opposable. (See discussion in section 5 above.)
