"Some of the most expressive uses of the language, however, result from the inspirations that break the rules and, in doing so, create an impression or "feel" that is beyond the rational. I'm alluding, of course, to poetry."

In a "poetic" sense, there is truth in what you say, leveller, but, having studied poetry, it strikes me that there tend to be even more rules about structure and the assignment of meaning than in regular language.
