Let me add that the line “The question may arise: ‘Why can’t a set of powerful, memorable lines be called a poem, even if they don’t rhyme?’” which you quoted from my post was in fact your own text, accidentally left undeleted. Now then…
That really is the point, isn’t it? I have defined poetry as rhyming, and Dr. Peikoff has defined it as “the art whose medium is the sound of concepts.”
The essential point here is that Peikoff is right and you are wrong. Peikoff correctly grasps the fact that rhyming is just one of a number of forms that embody the definition of poetry, and you, rationalistically, do not accept the error of your definition. It’s bad analogy, although not unforgivable, because Modern English poetry is rhyming. You are apparently unaware of the existence of other poetry (I should say that I think haiku stinks unless it is written in Japanese).
I was thrown off by, among other things, the fact that he gave no examples of non-rhyming poetry, and he insisted that half-rhymes (like food-good) were “junk” as he put it. But what would a non-rhyming poem be?
My god, have you not been reading the posts in this thread? Virtually every piece of poetry that does not descend from Arabic tradition – Arabic poetry, and Western European posetry since the Middle Ages. The entirety of Classical Greek and Latin poetry, Biblical Hebrew poetry, the Kalevala, Beowulf, the Niebelungenlied, every frigging sloka of Sanskrit poetry. You’ve had a dose of Greek, Latin, Old English. Here, for chuckles, is the opening of the Kalevala:
Mieleni minun tekevi, aivoni ajattelevi
lähteäni laulamahan, saa’ani sanelemahan,
sukuvirttä suoltamahan, lajivirttä laulamahan.
Sanat suussani sulavat, puhe’et putoelevat,
kielelleni kerkiävät, hampahilleni hajoovat.
Veli kulta, veikkoseni, kaunis kasvinkumppalini!
Lähe nyt kanssa laulamahan, saa kera sanelemahan
yhtehen yhyttyämme, kahta’alta käytyämme!
Harvoin yhtehen yhymme, saamme toinen toisihimme
näillä raukoilla rajoilla, poloisilla Pohjan mailla.
Free verse is not poetry because it lacks any formal sound-based structure – no metrical pattern, no alliteration, no rhymes.
