Here is an unavoidable question raised by Bloom:
"INEVITABILITY," unavoidable phrasing, seems to me, then, a crucial attribute of great poetry. But how can a reader tell, for herself, whether a poem she has never seen before possesses the quality of authentic poetry? As you read a poem, there should be several questions in your mind. What does it mean, and how is that meaning attained? Can I judge how good it is? Has it transcended the history of its own time and the events of the poet's life, or is it now only a period piece?
