On correspondence........................

We begin in infancy by establishing correspondence of eyes with eyes.  We recognized that we could do the same things with them.  We went on to the visible motion of the lips - smile answered smile....So far so good.  From here all the wonder grows.  It has been said that recognition in art is all.  Better say correspondence is all.  Mind must convince mind that it can uncurl and wave the same filaments of subtlety, soul convince soul that it can give off the same shimmers of eternity.  At no point would anyone but a brute fool want to break off this correspondence.  It is all there to satisfaction; and it is salutary to live in the fear of its being broken off.

-Robert Frost, from his introduction to E. A. Robinson's 1935 poem, King Jasper
