Letters reveal that Tolkienās conception of Orcs is fundamentally human, albeit humans that represent the worst sort of infantryman. In one 1954 letter, in fact, Tolkien goes so far as to describe orcs as fundamentally āārational incarnate' creatures, though horribly corrupted, if no more so than many Men to be met today.ā In another, he remarks that in real life, orcs would be present on both sides of any conflict. ButĀ Lord of the Rings,Ā after all, is intended to be romantic fantasy in the classical sense, akin to Arthurian sagas or mythology, and in such stories āgood is on one side and various modes of badness on the other. In real (exterior) life men are on both sides: which means a motley alliance of orcs, beasts, demons, plain naturally honest men, and angels.ā
Yet if orcsĀ areĀ essentially people, then that opens up a serious can of worms. Tolkien was a devout Catholic, and while he professed himself allergic to the sorts of didactic Christian allegories produced by his friend C.S Lewis, he was deeply interested in the moral dimensions of his work. And as a Catholic, the notion of an entirely irredeemable species bothered him.
Tolkienās dilemma was this: The world of Middle Earth, though full of various minor gods and spirits, is organized along roughly monotheisticāand thus, for Tolkien, Christianālines, with an Creator God, angels both ethereal and fallen, and a devil. This devil could not have created orcs evil out of whole cloth, Tolkien decided, because according to his understanding of Catholicism, evilĀ canātĀ truly create anything of its own: it can only pervert and ruin existing materials. Similarly, by being of the world created by God and with the tacit permission of God, orcs therefore are his children as muchĀ as anyone elseās ā meaning that salvation is as possibleĀ for them as anyone else.
