"These things—the beauty, the memory of our own past—are good images of what we really desire; but if they are mistaken for the thing itself they turn into dumb idols, breaking the hearts of their worshippers.  For they are not the thing itself; they are only the scent of a flower we have not found, the echo of a tune we have not heard, news from a country we have never yet visited.  Do you think I am trying to weave a spell?  Perhaps I am; but remember your fairy tales.  Spells are used for breaking enchantments as well as for inducing them.  And you and I have need of the strongest spell that can be found to wake us from the evil enchantment of worldliness which has been laid upon us for nearly a hundred years."    —C. S. Lewis, The Weight of Glory
