  But this aside, it is doubtful that the wills of two essentially omnipotent beings, at least, could differ in the manner Morris suggests. For suppose they can. Then, where x and y are both essentially omnipotent, and s is some contingent state of affairs that is within the range of omnipotence, x can make y impotent with respect to s (and vice versa). For even though it is intrinsically possible for y to determine whether or not s will occur, x, merely by willing s, makes it impossible for y to will not-s. That is, x, as it were, takes power over s out of y’s hands. Whether or not s occurs, in other words, is no longer up to y. Yet surely, if y is essentially omnipotent, and s is within the range of its power (as it must be if y is essentially omnipotent), no contingent circumstance of this sort could make it impotent with respect to s. (For a similar argument see Scotus’s seventh proof of unicity [Scotus, 90–1].)
