. . . let me illustrate what full dimensionality is by stepping away from poetry for a moment.
Think instead of pop music: why did Sinatra have the impact that other singers didn’t, and why did the Beatles spur Beatlemania—why is there no Gerry and the Pacemakers-mania? It’s because the Beatles’ work was fully dimensional. Those songs contain every emotion we’ve ever felt, and they hint at mysteries we can’t articulate; in other words, you get the whole roller coaster ride.
