This basically amounts to 200+ pages of DeLillo excerpts, organized by theme. The material is mostly left to speak for itself; the commentary mostly just rearticulates the concerns in each passage. But that's by design.

The thesis here should be pretty obvious to readers. DeLillo is interested in exploring the interconnectedness of things. 

When reading just about any DeLillo, you get a sense that everything is a manifestation of a larger process or system. At one extreme, we have the small, day-to-day concerns. Waste, sport, haircuts. At the other, we have nuclear disaster, terrorism, commerce, and death.  Naas refers to this as "contrabanding," or the reconciliation (or juxtaposition) of these extremes. 

I'm oversimplifying, but it sounds about right to me.

And again, 200+ pages of DeLillo quotes. What more could you want?
