No civilization has ever been entirely able to delete rumors of land beyond. These rumors of a lost Eden come to us in stories, poetry, flashes of joy, aching desire which are, as CSL recognized: “the sent of a flower we have not found, the echo of a tune we have not heard” (Weight of Glory)
Lewis speaks about this aching desire in Mere Christianity, when he writes:
“If I find in myself a desire for which no experience in this world can satisfy, the most probable explanation is that I was made for another world… Probably earthly pleasures were never meant to satisfy it, but only to arouse it. If that is so, then I must take care, on the one hand, never to despise or be unthankful for these earthy blessings, but on the other hand never to mistake them for something else of which they are only a copy, or echo, or mirage. I must keep alive my desire from my true county which I shall never find until after death.” (Mere Christianity)
