I have a burning and probably not immediately answerable question: Who is Dr. Lazlo Jamf?
Almost every thread of GR links back to him, yet I feel I don't really know him. We know a fair amount of details about him and his work, but I only feel that I've "heard of him" but not "met" him like I have with Pynchon's other characters.
With that out of the way, I particluarly liked the use of yin-Yang at the end of part 2 to illustrate the inexorable connection between Roger and Pointsman. The system of Yin and Yang is a binary one like Pointsman who may only exist at zero or one. However, regardless of their contrast to each other, they exist as a blended entity in nature. By that token, Roger, lying in the infinite domain from zero to one, provides the necessary link between Pointsman's binary universe and the far more complex real world of a war. In that same real world of a war where man's law and nature's law stand in open conflict, Roger faces the loss of Jessica, his salvation. Roger is among elect, the war has not passed him by costing him his salvation. "Lord Acton always sez, History is not woven by innocent hands" (281).
On the lighter side of things, I can't ever recall reading a book where a character smokes a joint and then proceeds to get the munchies (p372 "'I'm really hungry,' it occurs to Slothrop")
