What is the author's style in The Promise of American Life by Herbert Croly?

In The Promise of American Life,Croly presents his political ideas in the form of a narrative. He relates the political history of the United States and of several European nations as a story. He also tells the stories of a large number of statesman who have been influential throughout the course of American politics. In putting forth his ideas in the form of a story, one might think it would make Croly's book more accessible to the average reader. Unfortunately, this is not the case.
