Does poetry exist?

Suitable for Mixed Company posted a quote today from C.S. Lewis's Reflections on the Psalms.

I liked the end of the quote best:

"analyse the printer's ink and the paper, study it (in that way) as long as you like; you will never find something over and above all the products of analysis whereof you can say "This is the poem". Those who can read, however, will continue to say the poem exists."
