"You were saying that once when visiting Yale, you were struck that unlike Pound, Williams's thinking was volatile, I mean, did not stay locked into a pattern of concepts that then defined his subsequent necessary behavior, whereas Pound did"

This quote by Robert Creeley is describing the distinction between the thinking about Ezra Pound and William Carlos Williams. When Creeley visited Yale, he discovered that Williams' thinking was not fixed and did not stay locked into a pattern of concepts that then defined his subsequent behavior. In contrast, Pound's thinking was more rigid and remained locked into a pattern of ideas that then defined his subsequent habits. This recommends that Pound was more likely to stick to a set of beliefs and ideas, while Williams was more available to change and new ideas. This quote highlights the differences between the 2 poets and their particular techniques to thinking. It likewise recommends that Pound was more likely to be consistent in his thinking, while Williams was most likely to be available to new ideas and change.
