The real surge of interest in Tolkien's writing has been among high school and college students. Students make strange and varied works their own, and if there is any significance to their adoption of The Lord of the Rings—beyond the fact that it's a good book—the hell with it; one or another of our explainers of the young will take note of it pretty soon. But there is one possible reason for Tolkien's popularity that I would like to put forward, because it concerns the real strength of The Lord of the Rings. Young people in general sense the difference between the real and the phony. They don't know it—when they begin to know that difference, and to try to articulate it, then they are adults and subject to all the pains and fallibilities of that state. They can be misled by fools or madmen, but they sense the preacher who doesn't feel a word of his sermon, the mountebank who is putting them on, the society that does not believe in itself. They rarely take a phony of any sort to their hearts.

Tolkien believes in his world, and in all those who inhabit it. This is, of course, no guarantee of greatness—if Tolkien weren't a fine writer, it could not make him one—but it is something without which there is no greatness, in art or in anything else, and I find very little of it in the fiction that purports to tell me about this world we all live in. This failure of belief on the authors' part is, I think, what turns so many books that mean to deal with the real things that really happen to the real souls and bodies of real people in the real world into the cramped little stages where varyingly fashionable marionettes jiggle and sing. But I believe that Tolkien has wandered in Middle-earth, which exists nowhere but in himself, and I understand the sadness of the Elves, and I have seen Mordor.

And this is the source of the book's unity, this deep sureness of Tolkien's that makes his world more than the sum of all its parts, more than an ingenious contrivance, more than an easy parable of power. Beyond the skill and invention of the man, beyond his knowledge of philology, mythology and poetry, The Lord of the Rings is made with love and pride and a little madness. There never has been much fiction of any sort made in this manner, but on some midnights it does seem to me that my time is cheating itself of even this little. So I have read the tale of the Ring and some other books many times, and I envy my children, who have not yet read any of them, and I envy you if you have not, and wish you joy. (pp. xv-xvi)
