To present the conflict between Good and Evil as a war in which the good side is ultimately victorious is a ticklish business. Our historical experience tells us that physical power and, to a large extent, mental power are morally neutral and effectively real: wars are won by the stronger side, just or unjust. At the same time most of us believe that the essence of the Good is love and freedom so that Good cannot impose itself by force without ceasing to be good.
The battles in the Apocalypse and “Paradise Lost,” for example, are hard to stomach because of the conjunction of two incompatible notions of Deity, of a God of Love who creates free beings who can reject his love and of a God of absolute Power whom none can withstand. Mr. Tolkien is not as great a writer as Milton, but in this matter he has succeeded where Milton failed. As readers of the preceding volumes will remember, the situation n the War of the Ring is as follows: Chance, or Providence, has put the Ring in the hands of the representatives of Good, Elrond, Gandalf, Aragorn. By using it they could destroy Sauron, the incarnation of evil, but at the cost of becoming his successor. If Sauron recovers the Ring, his victory will be immediate and complete, but even without it his power is greater than any his enemies can bring against him, so that, unless Frodo succeeds in destroying the Ring, Sauron must win.
Evil, that is, has every advantage but one-it is inferior in imagination. Good can imagine the possibility of becoming evil-hence the refusal of Gandalf and Aragorn to use the Ring-but Evil, defiantly chosen, can no longer imagine anything but itself. Sauron cannot imagine any motives except lust for domination and fear so that, when he has learned that his enemies have the Ring, the thought that they might try to destroy it never enters his head, and his eye is kept toward Gondor and away from Mordor and the Mount of Doom.
Further, his worship of power is accompanied, as it must be, by anger and a lust for cruelty: learning of Saruman’s attempt to steal the Ring for himself, Sauron is so preoccupied with wrath that for two crucial days he pays no attention to a report of spies on the stairs of Cirith Ungol, and when Pippin is foolish enough to look in the palantir of Orthanc, Sauron could have learned all about the Quest. His wish to capture Pippin and torture the truth from him makes him miss his precious opportunity.
Read it all (my emphasis).
