Ouch.

I think that "Sound and Complete Models of Contracts" might be the most difficult paper I've ever tried to read. I feel like I'm drowning in an ocean of stuff I don't understand, and every now and then a piece of driftwood (representing the occasional part that I do understand) floats up and I clutch at it for a while, and just when I'm starting to catch my breath, a giant wave comes along and rips it out of my grasp. Then the piece of driftwood comes back and bonks me on the head.
