I have an alternate view. First, I would dispense with the following.
Written poetry has almost always been a preserve of the elite. Even popular literacy has hardly ameliorated this. Through poetry, poets speak to each other and about each other to educated audiences. The dialogue between poets crosses milennia, and it is truly an astonishing thing to watch if you know what to look for.
It helps to learn how to understand the language. Traditionally, only elites or those who pretend to be elite have had the time or the inclination to do the above. Unfortunately, this hasn’t changed enough. A lot of people miss out on some great stuff because teachers, critics, and others don’t make it very accessible.
But as others mentioned, like prose, there are many poets who do violence to this poetic language and who simply lack skill. Understandably this puts a lot of people off. However, if you make an effort to hear the music of the verse or to interpret some of the language, even reading a mediocre or poor poem is a worthwhile experience.
I read poetry. I had a fairly literary education and I read on the train every day. I translate from Latin, Greek, Occitan, Old English, and a few other flavors of French and German thrown in there. I am learning Sanskrit now. My favorite poets in English are Pound and Keats, neither exactly obscure or recherche. I love them both for very different reasons.
I read poetry for a lot of reasons. I love the feeling of reading words aloud that I find beautiful. I love the refinement of expression and the perfection of Vergil’s form along with the chaos and malevolence of Ezra Pound. I love the way Pound creates incredible tapestries of meaning that tie together countless times, places, and languages in a few terse phrases. I cannot get enough of Keats’ dreamy imagination and relentless high-mindedness. Horace’s complex blend of suavity, urbanity, and simplicity are confounding and exquisite.
Poetry is not refuge in obfuscating language. The language is the meaning, it does not conceal the meaning. Poetry can be hermetic on purpose, because there is learning and discovery in the act of dissecting poetry. The goal is not arriving at a predetermined meaning but expanding one’s capability for thought by responding to something on the page.
Reading good, I mean, really good poetry is like dropping a little depth charge in your brain. You read it, and perhaps it makes a favorable impression. It sits there in the murk, waiting for the right time. Then something happens in your life that calls to mind a word, a phrase, even a couplet. The verse then takes on a meaning of its own, or perhaps you understand it in a new or unexpected way. In these moments of realization, life is truly enhanced by art.
I treasure these kinds of moments. I treasure the times when I am living my prosaic life and something reminds me of a few words Catullus wrote two thousand years ago. Perhaps I gain some new insight into my own life or regarding the way I view myself. Sometimes I just like to hear the words bounce around in my head.
I couldn’t get the phrase, “Cabestan’s heart in a dish! Tis, tis, ytis!” out of my head in the shower the other day. It is a moment of extreme pathos in Pound’s Cantos. Though the scene is not exactly uplifting, it made me smile while I was brushing my teeth. There aren’t a whole lot of other art forms that you can take around with you wherever you go.
