You call a star a star, and say it is just a ball of matter moving on a mathematical course. But that is merely how you see it. By so naming things and describing them you are only inventing your own terms about them. And just as speech is invention about objects and ideas, so myth is invention about truth.
But, said Lewis, myths are lies, even though lies breathed through silver. No, said Tolkien, they are not.. Just as speech is invention about objects and ideas, so myth is invention about truth. 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. 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.
