Chesterton predicts Tolkien

All Christianity concentrates on the man at the cross-roads. The vast and shallow philosophies, the huge syntheses of humbug, all talk about ages and evolution and ultimate developments. The true philosophy is concerned with the instant. Will a man take this road or that? -- that is the only thing to think about, if you enjoy thinking. The aeons are easy enough to think about, anyone can think about them. The instant is really awful: and it is because our religion has intensely felt the instant, that it has in literature dealt much with battle and in theology dealt much with hell. It is full of danger, like a boy's book: it is at an immortal crisis. There is a great deal of real similarity between popular fiction and the religion of the western people.

-- G. K. Chesteron, Orthodoxy
