The promising young poets, the hopefuls? I'd name Richard Wilbur, Peter Viereck, Karl Shapiro, Elizabeth Bishop, Robert Lowell, John Ciardi...Leonard Bacon...but it is still too early to assertions. They're all 'in the field.' It remains to be seen how many will cross the finish line.
There are no two things as important to us in life and in art as being threatened and being saved. What are ideals of form for if we aren't going to be made to fear for them? All our ingenuity is lavished on getting into danger legitimately so that we may be genuinely rescued.
The figure a poem makes. It begins in delight and ends in wisdom... in a clarification of life - not necessarily a great clarification, such as sects and cults are founded on, but in a momentary stay against confusion.
