Even poets will often have difficulty defining exactly what a poem is. As if there’s a single measure for poetry to begin with.
To call it “slow prose” seems to me to slight both poetry and prose. Robert Bly once faulted traditional English-language poetry for the way it’s commonly functioned in the role of sermons, with any inherent wildness diluted or tamed. How much politeness can a poem contain, anyway?
One distinction might arise in parallels to music. There are good reasons composers set poetry and not prose to a score – and not all of them have to do with metrics or form. A good poem has much of the indefinable emotional sensation of listening or performing music, apart from any linear explanation. Both somehow take us into the darkened recesses of our soul.
Maybe I’ve come too much under the spell of what Bly instead calls “leaping poetry,” which can be found throughout the oral traditions of so-called primitive peoples or in many pages of Scripture, including the Bible, or in the visions of Asian, Latin American, or French poetic seers.
Not that it’s easy to veer far from our roots in linear composition, or at least speech. Many contemporary poems obviously arise as a strand of journaling or even confession – and I’ll plead guilty there, too, though hopefully I’ve compressed, distilled, and transformed my material into something, well, full of imagery and free flight that makes a particular become universal as well.
There’s also the continuing struggle of just how far a poem can run from the very basis of language itself and still communicate some underlying sensation or experience. Choosing pieces to read before an audience, as I’ve found, can lead to a much different selection than I’d have for on-page presentation, where more linguistically fragmented work might be more engaging.
Could it be, then, that the question then isn’t so much what a poem is but rather what it are? And then, how many of those elements exist in this work or that?
More to the point: Can a computer READ poetry? Metaphor really is a different way of thinking, one based on feeling and emotion.
