What is the author's style in Ways to Live by William Stafford?

It is not very unusual for a poem to be broken down into numbered sections the way that "Ways to Live" is. The most frequent observation about such poems is that each of the four segments, each of which has its own individual title, could stand by itself as an independent poem. This may be true, but once that is established, it helps to consider why Stafford decided to present them as one entire unit. There are similar themes that run through all of the sections of this poem, drawing relationships between them even when the subject matter of each might seem unrelated to the rest.
