Poetry: The art of making writing extremely convoluted and obfuscated. Hell, sometimes writers themselves don't even know how to "interpret" those beasts.
I understand. I feel that way with music, some good films and good books. But can poetry (which for most people you have to fight your way through a dictionary to get a glimpse about the actual meaning of the poem) really replicate the same feeling?
1. Your brain is some mesh of neurons that is approximately structured to process everyday information (normal vision, standard language, etc)
2. Art is non-everyday information that flows through your brain in an atypical way.
3. This atypical information flow can trigger mental states that would be hard to achieve with typical information flow.
That said, whether that achieved mental state is valuable to the observer is a matter of taste.
