Poetry is frequently characterized as a rhythmical poem meant to communicate pleasure through attractive, inventive, or elevated concepts. While this definition is accurate, it leaves out an important aspect of poetry: meaning. Poetry with meaning is called "poetic prose." Poetry can also be defined as the art of making sounds meaningful. Dialectic verse is a term used to describe a type of poetry that uses logic and argumentation as its principal tools for interpretation. It is often associated with Aristotle's Poetics, which was written about 350 B.C. This kind of poetry attempts to understand what is implied rather than simply describing what is seen. As Aristotle says in the book: "The poet should appeal to the intellect of his audience more than their emotions; he should make them think as well as feel." Many great poets have been considered dialecticians including Alexander Pope, John Milton, George Herbert, and William Wordsworth. Today, these are just some of the many poets known as "dialectists." Pope is probably the most famous modern-day dialectician because of his three-part epic poem The Iliad. The Iliad is composed of 14 books that explain how and why war began between Greeks and Trojans.
