The Christian and the Materialist hold different beliefs about the universe. They can't both be right. The one who is wrong will act in a way which simply doesn't fit the real universe. Consequently, with the best will in the world, he will be helping his fellow creatures to their destruction.

C. S. LewisThe value of the myth is that it takes all the things we know and restores to them the rich significance which has been hidden by โthe veil of familiarity.โ The child enjoys his cold meat, otherwise dull to him, by pretending it is buffalo, just killed with his own bow and arrow. And the child is wise. The real meat comes back to him more savory for having been dipped in a storyโฆby putting bread, gold, horse, apple, or the very roads into a myth, we do not retreat from reality: we rediscover it.
