From Columbia University Press:

Question: Let’s talk about the structure of the book. Among the first things that come to mind looking at the table of contents is the balance among the two parts, four chapters, and twelve sections. Also, although all sections are the same length, chapters 2 and 4 contain many more notes than the other two chapters. Why is this?

61Ru7PWavKL GV: The last systematic book I wrote was Il soggetto e la maschera [The Subject and the Mask] (1974). There are various reasons why I stopped taking so much care in explicating my thesis though balanced order and style: perhaps for the same reasons as Derrida, Rorty, and so many other postmetaphysical philosophers, that is, the end of grand narratives, truth, and ideology? I’m glad Santiago persuaded me to follow this structure because it certainly helps the reader, who, in this case, we hope will be not only philosophical but also political.

SV: Those chapters contain many more notes because we needed to justify with documents, articles, and other information some of our theses, for example, how Obama has increased military spending or Chávez has forced the oil industry to finance free health care for the poorest citizens of Venezuela. But if these chapters had to have more notes it’s also because they are the “ontic” sections of the book; that is, while chapters 1 and 3 are philosophical or ontological, chapters 2 and 4 are ontic or political. I’m not saying they could be read independently, but they correspond to each other. While part 1, “Framed Democracy,” is really a deconstruction of the “winners’ history,” that is, of the conservative realist positions of John Searle, Robert Kagan, and Francis Fukuyama, part 2, “Hermeneutic Communism,” outlines (through the work of Jacques Derrida, Richard Rorty, and others) how the “anarchic vein of hermeneutics” points toward a weakened communism.
