It has been said that a poem should not mean but be. This is not quite accurate. In a poem, as distinct from many other kinds of verbal societies, meaning and being are identical. A poem might be called a pseudo-person. Like a person, it is unique and addresses the reader personally. On the other hand, like a natural being and unlike a historical person, it cannot lie.
