A snippet from Tolkien: A Biography, by Humphrey Carpenter.
This is from his account of the long night’s conversation among Tolkien, C.S. Lewis, and Hugo Dyson at Oxford in 1931, which bore fruit a few days later in Lewis’s conversion. It’s tremendously important.
We have come from God (continued Tolkien), and inevitably the myths woven by us, though they contain error, will also reflect a splintered fragment of the true light, the eternal truth that is with God. Indeed only by myth-making, only by becoming a ‘sub-creator’ and inventing stories, can Man aspire to the state of perfection that he knew before the Fall. Our myths may be misguided, but they steer however shakily towards the true harbour, while materialistic ‘progress’ leads only to a yawning abyss and the Iron Crown of the power of evil….
Lewis listened as Dyson affirmed in his own way what Tolkien had said. You mean, asked Lewis, that the story of Christ is simply a true myth, a myth that works on us in the same way as the others, but a myth that really happened? In that case, he said, I begin to understand.
