I find myself, like many of you, enjoying this book despite the density of every paragraph. Pynchon has done an amazing amount of research and frankly I'm a little embarrassed at the effort it takes me to read his book: I can't even imagine writing it.
One of the most rewarding things about reading this are the simple descriptions Pynchon provides. Often he couples a noun with an adjective that fits so perfectly that you wonder why the two words aren't used together more often. "A cold smear of sun", "slate shadows", "a silly bleeding smile".....they sound so natural and describe something so perfectly that I sometimes have to stop and think if I've heard them before.
I'm echoing others of you again when I say that I've found Roger and Jessica's relationship the most interesting aspect of the novel so far. My favorite part was in the "They are in love. Fuck the war" section. Just before this much-loved quote is "It is marginal, hungry, chilly--most times they're too paranoid to risk a fire-but it's something they want to keep, so much that to keep it they will take on more than propaganda has ever asked them for." In short, when they go to this house they subject themselves to conditions that are much worse than the conditions that the war forces them into, and they're happy they get the chance to do so. In the rest of the novel war is the defining blackness-and-all-that-is-bad in the world, so much so that Jessica can't remember what life was like before the war and Roger assures her that it was "damned silly, that's all. Worrying about things that don't..."(60). The war completely changed life to be altogether more depressing, and still R&J voluntarily seek out war-like conditions, all in the name of love. This is an interesting study of motivation, which is another recurrent theme in this novel, especially as it relates to Pavlov.
